Description

A vortex fan control method, system, storage medium and intelligent terminal

Technical Field

The present application relates to the field of vortex blowers, and in particular to a vortex blower control method, system, storage medium and intelligent terminal.

Background technique

Vortex blower is a kind of high pressure blower, also called ring blower, which is widely used in aquaculture, injection molding machine, welding equipment, air dust removal, environmental water treatment and air flow transportation industries.

When the impeller of the vortex air pump rotates, the air between the impeller blades is affected by the centrifugal force and moves toward the edge of the impeller, where the air enters the annular cavity of the pump body, and then returns to the impeller, and circulates again from the starting point of the blades in the same way. Since the air is evenly accelerated, the circulating airflow generated by the rotation of the impeller causes the air to rush out in the form of a spiral, so the air leaves the pump body with extremely high energy for use.

With respect to the above-mentioned related technologies, the inventors believe that in order to prevent dust from entering, filters are often used to prevent dust from being sucked in during the suction working state. However, the filters are prone to impurities being attached after long-term use, which affects the air outlet efficiency, and there is still room for improvement.

Summary of the invention

In order to improve the problem that the filter is prone to impurities being attached to it during long-term use, thus affecting the air outlet efficiency, the present application provides a vortex blower control method, system, storage medium and intelligent terminal.

In a first aspect, the present application provides a vortex fan control method, which adopts the following technical solution:

A vortex fan control method, comprising:

The wind pressure on both sides of the filter is obtained, the inner wind pressure is defined as the inner pressure information, and the outer wind pressure is defined as the outer pressure information;

Calculate the wind pressure difference information between the internal pressure information and the external pressure information;

Determining whether the wind pressure difference information exceeds the preset critical wind pressure difference information;

If the critical wind pressure difference information is exceeded, a matching analysis is performed based on the congestion degree information and wind pressure difference information stored in the preset congestion database to determine the congestion degree corresponding to the wind pressure difference information, and the congestion degree is defined as the total congestion degree information;

Acquire the blocked surface image information and identify the blocked feature information in the blocked surface image information;

Perform matching analysis on the flapping frequency information, the total congestion degree information and the congestion characteristic information stored in the preset cleaning database to determine the flapping frequency corresponding to the total congestion degree information and the congestion characteristic information, and define the flapping frequency as the cleaning flapping frequency information;

Perform matching analysis based on the fan power information and the cleaning and flapping frequency information stored in the preset power database to determine the fan power corresponding to the cleaning and flapping frequency information, and define it as the cleaning power information;

The fan blows the blades on the wind wheel installed inside the filter with the power corresponding to the cleaning power information until the wind pressure difference information does not exceed the preset critical wind pressure difference information;

If it does not exceed, it works normally.

By adopting the above technical solution, a flapping wind wheel is arranged on the rear side of the corresponding filter. When the filter is blocked due to suction, the blades on the wind wheel flap the filter. The filter has a certain elasticity. When the impeller flaps at a fixed frequency, the filter also resonates, thereby separating the blockage on the filter from the filter and then blowing it out of the air outlet with the high-pressure wind at the rear. There is no need to manually disassemble the filter, and there is no need to set an interval time to clean the filter, which improves the efficiency and timeliness of filter cleaning.

Optionally, the method of blowing the blades on the wind wheel installed inside the filter screen with the power corresponding to the cleaning fan power information includes:

Filter out the blocked area information in the blocked surface image information according to the blocked feature information;

Performing a matching analysis based on the wind rotor number information and the blocked area information stored in the preset wind rotor database to determine the wind rotor number corresponding to the blocked area information, and defining the wind rotor number as the driving wind rotor number information;

Calculate regional congestion degree information based on the congestion area information and the preset regional area information;

Perform matching analysis on the flapping frequency information, regional congestion degree information and congestion characteristic information stored in the cleaning database to determine the flapping frequency corresponding to the regional congestion degree information and the congestion characteristic information, and define the flapping frequency as regional flapping frequency information;

Perform matching analysis based on the inner windshield angle information, the cleaning and flapping frequency information, and the regional flapping frequency information in the preset windshield database to determine the inner windshield angle corresponding to the cleaning and flapping frequency information and the regional flapping frequency information, and define the inner windshield angle as the regional windshield angle information;

The inner wind shield plates at the corresponding driving wind wheel number information are used to shield the wind according to the wind shield angle information in the area, and the inner wind shield plates with other numbers are used to shield the wind according to the preset full shield angle information.

By adopting the above technical scheme, the wind driving the wind wheel to rotate is partially blocked so that the frequency of the driving wind wheel rotation reaches the optimal state, so that the flapping frequency suitable for the area is targeted in each area, which will neither damage the blades due to excessive flapping nor achieve the cleaning effect due to weak flapping force, thereby improving the accuracy of flapping; on the other hand, other unblocked areas do not need to be flapped, so that the contact between the driving wind wheel and the filter is less here, thereby increasing the service life of the driving wind wheel.

Optionally, if the wind pressure difference information continues to decrease and the value remains unchanged and is greater than the critical wind pressure difference information, the method for controlling the fan includes:

Obtaining the blocked surface image information when the value of the wind pressure difference information remains unchanged and filtering out the corresponding blocked area information, defining the blocked surface image information at this time as abnormal surface image information, and defining the blocked area information at this time as abnormal area information;

Perform matching analysis on the wind rotor number information and the abnormal region information stored in the wind rotor database to determine the wind rotor number corresponding to the abnormal region information, and define the wind rotor number as the abnormal wind rotor number information;

The outer wind shield plates corresponding to the abnormal wind wheel number information are used to shield the wind at the preset half wind shield angle information, and the outer wind shield plates with other numbers are used to shield the wind at the preset full wind shield angle information;

The fan is driven in reverse according to the preset corrected power information to draw wind into the fan;

After the preset interval time information, the blades on the wind wheel installed inside the filter are blown again with the power corresponding to the cleaning power information to determine whether the value of the wind pressure difference information remains unchanged;

If it still remains unchanged, continue to reversely suction and obtain information on the number of reverse suction times;

Determine whether the reverse air suction frequency information is greater than the preset frequency threshold information;

If it is greater, the abnormal wind rotor number information and wind rotor damage information are output;

If it is less than, continue to obtain the reverse suction times information;

If the value of the wind pressure difference information decreases, the blades on the wind wheel installed inside the filter are blown with the power corresponding to the cleaning power information until the wind pressure difference information does not exceed the critical wind pressure difference information.

By adopting the above technical solution, since long-term flapping is likely to bend the blades of the wind wheel, causing the wind wheel to lose its cleaning effect, the wind wheel blades can be corrected by reverse suction to rotate in the opposite direction, thereby restoring the wind wheel's flapping ability. When the wind wheel is completely damaged, the wind wheel damage information and abnormal wind wheel number information are output to remind the user to replace it immediately, thereby improving the service life and replacement efficiency of the wind wheel.

Optionally, after the preset interval time information, the blades on the wind wheel installed on the inner side of the filter are blown again with the power corresponding to the cleaning power information. If the value of the wind pressure difference information remains unchanged, the method of continuing the reverse suction and obtaining the reverse suction number information includes:

The outer wind shield corresponding to the abnormal wind wheel number information is used to shield the wind at the half wind shield angle information and the outer wind shields with other numbers are closed according to the preset closing angle information, and then the internal pressure information is obtained, and the internal pressure information is defined as the detection internal pressure information;

Determine whether the detected internal pressure information is equal to the preset atmospheric pressure information;

If it is equal to the atmospheric pressure information, the fan is driven forward according to the preset impact power information and impact frequency information to squeeze and blow out the wind;

After the preset impact interval time information, the air is sucked back again and the internal pressure information is obtained again;

If the internal pressure information is still equal to the atmospheric pressure information, the impact number information is obtained;

Determine whether the impact number information is greater than the preset impact threshold information;

If it is greater, invalid impact information is output;

If it is less than, continue to impact until the internal pressure information is greater than the atmospheric pressure information or the impact number information is greater than the impact threshold information;

If it is not equal to the atmospheric pressure information, the abnormal wind wheel number information and wind wheel damage information are output.

By adopting the above technical solution, if the wind pressure difference information is not reduced after multiple corrections, it is also possible that the blockage just blocks the part of the area where the inner baffle is facing the wind at a semi-wind-shielding angle, so that the wind wheel will not rotate in the opposite direction. Therefore, by closing other areas and then blowing in the opposite direction to detect whether the internal air pressure is greater than the atmospheric pressure, it is detected whether this part of the area can be ventilated. If not, the remaining areas are closed and then subjected to a high-pressure shock to the area to flush out the blockage in the area, thereby removing the blockage and reducing the misjudgment of abnormal wind wheels, thereby improving the detection accuracy of abnormal wind wheels.

Optionally, if the impact number information is greater than the impact threshold information, the method for outputting the abnormal wind rotor number information and the wind rotor damage information includes:

Matching analysis is performed based on the impact angle information and abnormal wind wheel number information stored in the preset angle database to determine the impact angle of the area corresponding to the abnormal wind wheel number information that can impact the outer wind shield plate after the wind is shielded by the preset half wind shield angle information, and the impact angle is defined as water flow impact angle information;

After the water flow impacts from the outside at the angle of the water flow impact angle information, the fan is driven forward according to the preset impact power information and impact frequency information to squeeze and blow out the wind and repeat the impact;

When the internal pressure information is still equal to the atmospheric pressure information, the repetition number information is obtained;

Determine whether the repetition number information is greater than the preset repetition threshold information;

If it is greater, the abnormal wind rotor number information and wind rotor damage information are output;

If it is less than, the impact will continue to be repeated until the number of repetitions is greater than the repetition threshold or the internal pressure is greater than the atmospheric pressure.

By adopting the above technical solution, when the number of impacts is greater than the impact threshold information, if there is a blockage, the adhesion capacity of the blockage is large and it cannot be cleared by air pressure. Therefore, water flow is used to clean the area, thereby further reducing the impact of the blockage on the final wind wheel judgment result in the area, thereby improving the detection accuracy of the abnormal wind wheel.

Optionally, the method for checking the output abnormal wind rotor number information and wind rotor damage information includes:

Find out the normal wind wheel number information from the preset number database;

Calculate the rotation angle information according to the normal wind wheel number information and the abnormal wind wheel number information;

The filter is rotated according to the rotation angle information to obtain the wind pressure difference information again;

Determine whether the wind pressure difference information begins to decrease;

If yes, then output the abnormal wind rotor number information and wind rotor damage information;

If not, the filter abnormality information is output.

By adopting the above technical solution, by rotating the angle of the filter, the abnormal area is made to face the normal wind wheel, so as to determine whether the abnormality is caused by the filter or the wind wheel, thereby improving the detection accuracy of the abnormal wind wheel.

Optionally, a method for cleaning dust and water accumulated between the outer wind shield and the inner wall of the air duct is also included, the method comprising:

Obtain the maximum rotation angle information of the outer windshield;

Determine whether the maximum rotation angle information is greater than the preset maximum ventilation angle information;

If it is greater, it works normally;

If it is less than, all numbered outer wind shields are closed with full-closed angle information and all numbered inner wind shields are blocked with full-blocking angle information, and then the fan is driven forward according to the impact power information and impact frequency information to squeeze and blow out the wind and open the drain valve;

Re-obtain the maximum rotation angle information of the outer wind shield and re-determine whether it is greater than the maximum ventilation angle information;

If so, close the drain valve and work normally;

If not, an alarm message is output.

By adopting the above technical solution, due to the existence of the outer baffle, impurities and moisture will accumulate to a certain extent between the outer baffle and the air duct, and there is an outer baffle between this moisture and impurities and the air outlet, and it is not easy to clean them out from the air outlet. Therefore, by judging the rotation angle of the outer baffle, it is determined whether the internal impurities will affect the outer baffle to achieve full shielding or complete non-shielding functions. If it does, it will be discharged, thereby improving the functional integrity of the baffle.

In a second aspect, the present application provides a vortex fan control system, which adopts the following technical solution:

A vortex fan control system, comprising:

A wind pressure acquisition module is used to acquire the wind pressure on both sides of the filter, define the inner wind pressure as the inner pressure information, and define the outer wind pressure as the outer pressure information;

A processing module, connected to the wind pressure acquisition module and the judgment module, for storing and processing information;

The processing module calculates the wind pressure difference information between the internal pressure information and the external pressure information;

A judgment module, used to judge whether the wind pressure difference information exceeds the preset critical wind pressure difference information;

If the judgment module determines that the critical wind pressure difference information is exceeded, the processing module performs matching analysis based on the congestion degree information and wind pressure difference information stored in the preset congestion database to determine the congestion degree corresponding to the wind pressure difference information, and defines the congestion degree as the total congestion degree information;

An image acquisition module, connected to the processing module, is used to acquire the blocked surface image information and identify the blocked feature information in the blocked surface image information;

The processing module performs matching analysis on the flapping frequency information, the total congestion degree information and the congestion characteristic information stored in the preset cleaning database to determine the flapping frequency corresponding to the total congestion degree information and the congestion characteristic information, and defines the flapping frequency as the cleaning flapping frequency information;

The processing module performs matching analysis based on the fan power information and the cleaning and flapping frequency information stored in the preset power database to determine the fan power corresponding to the cleaning and flapping frequency information, and defines it as the cleaning power information;

The processing module controls the fan to blow the blades on the wind wheel installed inside the filter with the power corresponding to the cleaning power information until the wind pressure difference information does not exceed the preset critical wind pressure difference information;

If the judging module determines that it does not exceed, the processing module controls the fan to work normally.

By adopting the above technical solution, a flapping wind wheel is arranged on the rear side of the corresponding filter. When the filter is blocked due to suction, the blades on the wind wheel flap the filter. The filter has a certain elasticity. When the impeller flaps at a fixed frequency, the filter also resonates, thereby separating the blockage on the filter from the filter and then blowing it out of the air outlet with the high-pressure wind at the rear. There is no need to manually disassemble the filter, and there is no need to set an interval time to clean the filter, which improves the efficiency and timeliness of filter cleaning.

Detailed ways

In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with Figures 1-9 and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

The embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings.

Referring to FIG. 1 , an embodiment of the present invention provides a vortex fan control method. The main process of the vortex fan control method is described as follows:

Step 100: Obtain wind pressures on both sides of the filter, define the inner wind pressure as inner pressure information, and define the outer wind pressure as outer pressure information.

The internal pressure information is the information of the wind pressure on the side of the filter screen close to the inside of the fan. The external pressure information is the information of the wind pressure on the side of the filter screen close to the outside of the fan. The way to obtain it is a wind pressure sensor. When the fan starts to blow, the wind pressure sensor starts to obtain it.

Step 101: Calculate the wind pressure difference information between the internal pressure information and the external pressure information.

The wind pressure difference information is the difference between the internal and external wind pressures. The calculation method is numerical subtraction. Due to the existence of the filter, when the filter is subjected to resistance, there is wind pressure difference information between the internal pressure information and the external pressure information.

Step 102: Determine whether the wind pressure difference information exceeds the preset critical wind pressure difference information.

The critical wind pressure difference information is the information of the wind pressure difference value within the normal range, that is, when the value is greater than the difference, it is generally assumed that the wind pressure difference is generated after the blockage. This value is set by the staff and is the most reasonable result obtained by the staff based on the test of each fan. In this embodiment, it specifically refers to the wind pressure difference caused by the filter being seriously blocked and seriously affecting the operation of the fan and needing to be cleaned.

Step 1021: If the critical wind pressure difference information is exceeded, a matching analysis is performed based on the congestion degree information and wind pressure difference information stored in the preset congestion database to determine the congestion degree corresponding to the wind pressure difference information, and the congestion degree is defined as the total congestion degree information.

The total congestion degree information is the information of the congestion degree corresponding to the wind pressure difference information. Due to different congestion degrees, the corresponding wind pressure difference information is different, so one wind pressure difference information corresponds to one total congestion degree information. The database stores the mapping relationship between the total congestion degree information and the wind pressure difference information. It is summarized by the staff in this field after many experiments. When the wind pressure difference information is calculated and input, the system automatically finds the corresponding total congestion degree information from the database and outputs it.

When the wind pressure difference information exceeds the critical wind pressure difference information, it means that the filter is seriously blocked at this time, which seriously affects the operation of the fan, so it is necessary to find the corresponding blockage degree according to the database.

Step 1022: If not exceeded, then operate normally.

If it does not exceed, it means that it does not affect the operation of the fan at this time, so it can operate normally.

Step 103: Obtain the blocked surface image information and identify the blocked feature information in the blocked surface image information.

The blocked surface image information is the image information of the filter net seen from the outside. The acquisition method can be to shoot with a pinhole camera. That is, when the wind pressure difference information exceeds the critical wind pressure difference information, the system automatically turns on the camera to shoot. The blocked feature information is the feature information of the object blocked on the filter net, such as dust, soil, etc. The recognition method is to identify different colors from the image, and then identify the corresponding features and the area occupied by the features according to the color depth and transmittance. The purpose of recognition is also to determine the type of adsorption for subsequent cleaning.

Step 104: Perform matching analysis based on the flapping frequency information, total congestion degree information and congestion characteristic information stored in the preset cleaning database to determine the flapping frequency corresponding to the total congestion degree information and the congestion characteristic information, and define the flapping frequency as the cleaning flapping frequency information.

The cleaning and flapping frequency information is the cleaning and flapping frequency taken according to the blockage situation and the type of blocking object. As shown in Figure 2, a wind wheel is provided on the side of the filter away from the air outlet, and the number of wind wheels is several. The wind wheels are arranged along the circumference of the air duct. Here, the wind wheel is only defined as a flapping object, that is, the wind wheel is only provided with blades and a rotating shaft, without any driving source and retaining edge. When the blower blows air onto it, the blades of the wind wheel will be driven by the wind and flap the filter. It should be noted that the proportion of the wind wheel in the air duct is relatively small, and the channel in the middle is relatively large, which does not affect the working efficiency of the fan. The mapping relationship between the total blockage degree information, the blockage characteristic information and the cleaning and flapping frequency information is stored in the database, which is obtained by the staff in this field after multiple experiments and recording of relevant data to form a curve image, that is, several test points are used as accurate values here, and the remaining values are scientific simulation values, and the results of continuous neural network learning in subsequent work. When the total congestion degree information and congestion characteristic information are obtained, the system automatically searches the database for the corresponding cleaning and flapping frequency information and outputs it. It should be noted that this is the total cleaning and flapping frequency information. Even if less congestion characteristic information is identified in some areas, subsequent processing will still be carried out according to the cleaning and flapping frequency.

Step 105: Perform matching analysis based on the fan power information and the cleaning and flapping frequency information stored in the preset power database to determine the fan power corresponding to the cleaning and flapping frequency information, and define it as the cleaning power information.

The cleaning power information is the power information that the fan will cause the wind wheel to flap according to the cleaning flapping frequency information after the fan blows according to the cleaning power information. The database stores the mapping relationship between the cleaning flapping frequency information and the cleaning power information, and the staff in this field records it according to the actual cleaning flapping frequency information and the actual fan power. When the system finds the cleaning flapping frequency, it automatically finds the corresponding cleaning power information from the database and outputs it.

Step 106: The fan blows the blades on the wind wheel installed inside the filter with the power corresponding to the cleaning power information until the wind pressure difference information does not exceed the preset critical wind pressure difference information.

After obtaining the cleaning power information, the fan blows air from the inside to drive the wind wheel to rotate and continuously beat the filter in a counterclockwise direction (as shown in Figure 2). The filter here is a thin film with certain elasticity and relaxation. After beating, the impurities falling from the filter are blown out of the air duct along with the high-pressure wind and cleaned up. When the impurities on the filter are cleaned up, the wind pressure difference information does not exceed the critical wind pressure difference information.

3 , the method of blowing the blades on the wind wheel installed inside the filter screen with the power corresponding to the cleaning fan power information includes:

Step 200: filtering out blocked area information in the blocked surface image information according to the blocked feature information.

The blocked area information is the area information where the blocked characteristic information exists in the blocked image information, that is, the filter is divided into several areas. Here, the center point of the filter is the center of the circle and divided according to the angle, for example, every 60 degrees is a area. When the blocked characteristic information exists in the area, it is recorded as the blocked area information. If necessary, the areas are numbered to distinguish the location and range of the area corresponding to each number.

It should be noted that there is a wind wheel in an area to flap the area, so the area is divided according to the best flapping effect, which can be the best result obtained by the staff through a limited number of tests.

Step 201: performing a matching analysis based on the wind rotor number information and the blocked area information stored in the preset wind rotor database to determine the wind rotor number corresponding to the blocked area information, and defining the wind rotor number as the driving wind rotor number information.

The driving wind wheel number information is the number information of the wind wheel that flaps the area when there is a blockage in the area. The database stores the mapping relationship between the driving wind wheel number information and the blocked area information, that is, when the blocked area information is known, the corresponding flapping wind wheel is naturally known, so the corresponding number can be found from the database. The staff in this field will number the corresponding area during installation, and then record the two in one-to-one correspondence. When the system analyzes the blocked area information, it will automatically find the corresponding driving wind wheel number information from the database and output it.

Step 202: Calculate regional congestion degree information based on the congested region information and preset regional area information.

The regional blockage degree information is the blockage degree information in the region. Since the front image of the filter is taken, the blockage degree can be expressed to a certain extent by the ratio of the area occupied by the blockage in the region. In this embodiment, the corresponding area can be divided into several areas of the same area as small as possible. The image of the feature in the small area is defined as the area occupied by the feature, and then all occupied areas are calculated to obtain the blockage area information. The regional area information is the information of the area occupied by each area, which is set in advance, that is, after the area is divided into regions, the area of each area can be known. Here, the default is an equal division state, and the area and shape of each area are consistent. The calculation method is to divide the area value corresponding to the blockage area information by the regional area information.

Step 203: Perform matching analysis based on the beating frequency information, regional congestion degree information and congestion feature information stored in the cleanup database to determine the beating frequency corresponding to the regional congestion degree information and congestion feature information, and define the beating frequency as the regional beating frequency information.

The regional beating frequency information is information on the beating frequency of impurities corresponding to the blockage characteristic information in the region that can be removed from the filter by beating them according to the regional blockage degree information. The cleaning database stores the regional blockage degree information and the mapping relationship between the blockage characteristic information and the regional beating frequency information, which is obtained in the same manner as step 104. The difference between the two regions is that one is a test within the region and the other is a test as a whole. When the system learns the regional blockage degree information and the blockage characteristic information, it automatically finds the regional beating frequency information that can meet the requirements from the database and outputs it.

Step 204: Perform matching analysis based on the inner windshield angle information, cleaning and flapping frequency information, and regional flapping frequency information in the preset windshield database to determine the inner windshield angle corresponding to the cleaning and flapping frequency information and the regional flapping frequency information, and define the inner windshield angle as the regional windshield angle information.

The wind shield angle information in the area is the information of the angle after the wind shield in the area is rotated. Since the cleaning and flapping frequency information is obtained from the overall total blockage degree information, the wind pressure in each area is fixed. In order to make the rotation of different wind wheels targeted, an inner baffle is set. When the angle after the inner baffle is rotated is different, the contact surface between the wind wheel and the wind is different, thereby forming different rotation speeds of the wind wheel. Therefore, different wind wheel flapping frequencies can be generated by different inner baffles. The mapping relationship between the cleaning and flapping frequency information, the regional flapping frequency information and the internal wind shield angle information is stored in the database. It is obtained by theoretical calculations and multiple experiments by staff in this field and recorded in the database. When the system obtains the cleaning and flapping frequency information and the regional flapping frequency information, it automatically searches the database for the corresponding regional wind shield angle information.

Step 205: The inner wind shield plates corresponding to the driving wind wheel number information shield the wind according to the wind shield angle information in the area, and the inner wind shield plates with other numbers shield the wind according to the preset full shield angle information.

The full blocking angle information is to completely block the wind wheel so that the wind wheel will not rotate due to the horizontal wind force directly acting on it. In this embodiment, when the system knows the regional blockage degree information of all areas, the system automatically outputs the wind blocking angle information in the area, and then uses the inner wind shield plate at the corresponding regional wind wheel number information to block the wind according to the regional wind shield angle information. Then, since the remaining ones have no blockage feature information, the inner shield plate is arranged according to the full blocking angle information to make the wind wheels with other numbers less likely to rotate and be damaged, thereby increasing the service life of the wind wheel.

It should be noted that the height occupied by the wind wheel is not very large, and the rotation of the baffle has little effect on the flow rate of the wind in the air duct, so the drive of the wind wheel is mainly driven by horizontal wind force.

4 , if the wind pressure difference information continues to decrease and the value remains unchanged and is greater than the critical wind pressure difference information, the method for controlling the fan includes:

Step 300: Obtain the blocked surface image information when the value of the wind pressure difference information remains unchanged and filter out the corresponding blocked area information, define the blocked surface image information at this time as abnormal surface image information, and define the blocked area information at this time as abnormal area information.

The abnormal surface image information is the image information of the filter mesh surface obtained by shooting when the value of the wind pressure difference information remains unchanged and the wind pressure difference information is still greater than the critical wind pressure difference information. The acquisition method is to acquire it with a camera. The abnormal area information is the information of the area where the blocking feature is located in the abnormal surface image information. The acquisition method is the same as step 200. When the value of the wind pressure difference information remains unchanged and no longer decreases, and the wind pressure difference information at this time is still higher than the critical wind pressure difference information, turn on the pinhole camera to shoot and obtain the abnormal surface image information, and then identify the abnormal features and the abnormal area information according to the recognition function.

Step 301: Perform matching analysis based on the wind rotor number information and abnormal area information stored in the wind rotor database to determine the wind rotor number corresponding to the abnormal area information, and define the wind rotor number as abnormal wind rotor number information.

The abnormal wind rotor number information is the number information of the wind rotor at the abnormal area information. When the area is known, the number of the wind rotor can also be automatically found. The establishment and search process of the database is consistent with step 201, and will not be repeated here.

Step 302: The outer wind shield plates corresponding to the abnormal wind wheel number information are used to shield the wind at the preset half wind shield angle information, and the outer wind shield plates with other numbers are used to shield the wind at the preset full wind shield angle information.

The half wind shield angle information is the angle information of the outer wind shield plate that shields half of the wind rotor, so that the wind can have the maximum contact area with the wind rotor blades. The purpose of the operation here is to make the wind rotor corresponding to the abnormal wind rotor number information rotate so as not to waste the service life of other wind rotors.

Step 303: Drive the fan in reverse according to the preset corrected power information to draw wind into the fan.

The correction power information is the power information that can correct the wind wheel. This value is set manually so that the wind wheel can be corrected faster. The purpose of reverse drive is to correct the blades of the wind wheel so that the wind wheel rotates in the opposite direction. The correction can be performed by a correction plate, where the contact surface between the correction plate and the blade is larger than the contact surface between the blade and the filter, so that when the filter cannot be contacted, the correction plate contacts. The correction plate can be installed manually in the corresponding position. It can be disassembled when correction is not required.

Step 304: After the preset interval time information, the blades on the wind wheel installed inside the filter are blown again with the power corresponding to the cleaning power information and it is determined whether the value of the wind pressure difference information remains unchanged.

The interval information is a manually set time interval, such as 1 minute. After the interval, the system restarts forward to detect whether the correction is made.

Step 3041: If it remains unchanged, continue reverse suction and obtain reverse suction times information.

The reverse suction times information is the information of the reverse suction times, with the middle forward blowing as the cutoff point, that is, the reverse blowing between two forward blowings is counted as one time. If the value of the wind pressure difference information remains unchanged, it means that the correction is not successful at this time, then continue the reverse correction, and then obtain the reverse suction times information.

Step 3042: If the value of the wind pressure difference information decreases, the blades on the wind wheel installed inside the filter are blown with the power corresponding to the cleaning power information until the wind pressure difference information does not exceed the critical wind pressure difference information.

If the value of the wind pressure difference information decreases, it means that it has been corrected at this time, and normal cleaning begins, and the blades on the wind wheel installed on the inner side of the filter are blown according to the power corresponding to the cleaning power information.

Step 305: Determine whether the reverse air suction frequency information is greater than the preset frequency threshold information.

The number threshold information is the maximum number of times corresponding to the reverse suction number information, that is, after exceeding this number, it can be basically determined that the abnormality is not caused by filter clogging. This value is set manually by the staff based on long-term test results. The purpose of judgment is to determine whether it is caused by blade bending.

Step 3051: If it is greater than, output the abnormal wind rotor number information and wind rotor damage information.

The abnormal wind rotor number information is the information of the wind rotor number where the abnormality occurs. The wind rotor damage information is the information that the wind rotor has been damaged, which can be displayed in text. If it is greater than, it means that it is not a problem of correction, so it means that the blade is damaged and cannot be corrected at this time. At this time, the abnormal wind rotor number information and wind rotor damage information are output to remind the staff to quickly find the abnormal wind rotor for replacement.

Step 3052: If it is less than, continue to obtain the reverse suction times information.

If it is less than, it means that the number threshold has not been reached at this time, and it is impossible to determine whether the abnormality is caused by the filter clogging problem. Therefore, continue to observe until the reverse suction number information is greater than the preset number threshold information or the value of the wind pressure difference information decreases.

5 , after the preset interval time information, the blades on the wind wheel installed inside the filter are blown again with the power corresponding to the cleaning power information. If the value of the wind pressure difference information remains unchanged, the method of continuing to reversely suck air and obtaining the reverse suction number information includes:

Step 400: Obtain internal pressure information after the outer wind shield plate corresponding to the abnormal wind wheel number information blocks the wind at half the wind shield angle information and the outer wind shield plates with other numbers are closed according to the preset closing angle information, and the internal pressure information is defined as the detected internal pressure information.

The detected internal pressure information is the air pressure information located inside the filter after the outer windshield at the corresponding abnormal wind wheel number information blocks the wind with the half windshield angle information and the outer windshields with other numbers are closed according to the preset closing angle information. The closing angle information here is the information of the angle at which the corresponding area of the filter is closed. When the outer windshield adopts the closing angle information, the elastic soft plates behind and on both sides of the outer windshield are freed from the restraint and unfolded, resting on the filter, and closing the corresponding area. When the closing operation is completed, only the local area at the abnormal wind wheel number information is exposed, so that the wind only rushes to this area.

Step 401: Determine whether the detected internal pressure information is equal to the preset atmospheric pressure information.

The purpose of the judgment is to determine whether the local area in the corresponding filter is blocked.

Step 4011: If it is equal to the atmospheric pressure information, the fan is driven forward according to the preset impact power information and impact frequency information to squeeze and blow out the wind.

The impact power information is the information of the fan power that impacts the area when the area exposed after the outer wind shield is blocked by the half wind shield angle information. The impact frequency information is the information of the impact frequency at the interval time corresponding to the impact power information. Both data are artificially set values, and the impact power and frequency with the best test results within the maximum power shall prevail. If it is equal to the atmospheric pressure, it means that there is no wind passing through the area exposed after the outer wind shield is blocked by the half wind shield angle information, so this area is blocked by an obstruction, and the fan is driven forward according to the preset impact power information and impact frequency information to squeeze and blow out the wind, and impact the obstruction with impact force.

Step 4012: If it is not equal to the atmospheric pressure information, then output the abnormal wind wheel number information and wind wheel damage information.

If it is not equal to the atmospheric pressure, it means that the blockage in the area has been ruled out and the wind rotor cannot rotate in the opposite direction. Therefore, in the absence of other external factors, the remaining reason is the wind rotor damage. Therefore, the abnormal wind rotor number information and wind rotor damage information are output. The output method is the same as step 3051.

Step 402: After the preset impact interval time information, reverse air suction is resumed and the internal pressure information is re-obtained.

The impact interval information is a time interval set manually, such as 1 minute. After the impact interval, the reverse start is restarted to detect whether the blockage in the corresponding area is flushed out.

Step 403: If the internal pressure information is still equal to the atmospheric pressure information, the impact number information is obtained.

The impact times information is the number of impacts according to the impact interval time information, and the time of each impact is the impact interval time. If the internal pressure information is still equal to the atmospheric pressure information, it means that it has not been flushed out at this time, which means that it is still blocked at this time. In order to prevent useless work, the record of the impact times information is set.

Step 404: Determine whether the impact number information is greater than the preset impact threshold information.

The impact threshold information is a manually set critical value, that is, when it exceeds this value, it means that the impact has no effect. The purpose of judgment is to determine whether the impact is effective.

Step 4041: If it is greater than, output invalid impact information.

The invalid impact information is information that the blockage cannot be impacted to break through the filter. If it is greater than, it means that the impact with gas is ineffective at this time, and the invalid impact information is output.

Step 4042: If it is less than, continue the impact until the internal pressure information is greater than the atmospheric pressure information or the impact number information is greater than the impact threshold information.

If it is less than, it means that it is still impossible to determine whether the impact is effective at this time, so the impact will continue until the internal pressure information is greater than the atmospheric pressure information or the impact number information is greater than the impact threshold information.

6 , if the impact number information is greater than the impact threshold information, the method for outputting abnormal wind rotor number information and wind rotor damage information includes:

Step 500: Perform a matching analysis based on the impact angle information and abnormal wind wheel number information stored in the preset angle database to determine the impact angle corresponding to the abnormal wind wheel number information that can impact the area after the outer wind shield plate is shielded by the preset half wind shield angle information, and define the impact angle as the water flow impact angle information.

The water flow impact angle information is the angle corresponding to the area exposed after the water flow can impact the outer wind shield with half wind shield angle information. The database stores the mapping relationship between the water flow impact angle information and the abnormal wind wheel number information. It is obtained and input by the staff after installing the sprinkler head, filter screen and outer wind shield. When the system obtains the abnormal wind wheel number information, it automatically finds the corresponding water flow impact angle information from the database.

Step 501: After the water flow impacts from the outside at the angle of the water flow impact angle information, the fan is driven forward according to the preset impact power information and impact frequency information to squeeze and blow out the wind and repeat the impact.

After knowing the water flow impact angle, the water flow is impacted according to the impact angle to weigh down the impurities, and then the fan is driven forward according to the preset impact power information and impact frequency information to squeeze and blow out the wind. Due to the characteristics of the filter and the fan and the working environment, the particles attached to the filter are generally dust or soil, so the water flow can mix with them and increase their gravity and lose adhesion with the filter, thus detaching from the filter. Then, in order to flush it out, the fan is driven forward according to the preset impact power information and impact frequency information to squeeze and blow out the wind, so that the impurities attached to the water fly out from the air outlet.

Step 502: When the internal pressure information is still equal to the atmospheric pressure information, obtain the repetition number information.

The repetition number information is the number of times the water flow impacts for a preset time and then is blown out by the positive wind force. When the internal pressure information is still equal to the atmospheric pressure information, it means that the impact strength is insufficient, the water flow cannot mix with the impurities or the attached impurities are not completely washed off.

Step 503: Determine whether the repetition number information is greater than the preset repetition threshold information.

The repetition threshold information is a manually set critical value, that is, when it exceeds this value, it means that the water flow impact has no effect. The purpose of the judgment is to determine whether the water flow impact is effective.

Step 5031: If it is greater than, output invalid water flow impact information.

The invalid water flow impact information is the information that the blockage cannot be impacted by water flow to break through the filter. If it is greater than, it means that the impact by water flow has no effect at this time, and the invalid water flow impact information is output.

Step 5032: If it is less than, continue to repeat the impact until the number of repetitions is greater than the repetition threshold or the internal pressure is greater than the atmospheric pressure.

If it is less than, it means that it is still impossible to determine whether the water flow impact is effective at this time, and it is necessary to continue observing until the number of repetitions is greater than the repetition threshold or the internal pressure is greater than the atmospheric pressure.

Referring to FIG. 7 , the method for checking the output of abnormal wind rotor number information and wind rotor damage information includes:

Step 600: Find out normal wind wheel number information from a preset number database.

The normal wind rotor number information is the number information of the wind rotors that are working normally and whose blocking features in the area can be knocked off. The number database is a database that stores the numbers of all wind rotors and the corresponding areas. When the abnormal wind rotor number information is known, the remaining numbers that do not meet the abnormal wind rotor number information are automatically screened out, that is, the normal wind rotor number information.

Step 601: Calculate the rotation angle information according to the normal wind rotor number information and the abnormal wind rotor number information.

The rotation angle information is information about the angle required to rotate the area on the filter net corresponding to the abnormal wind wheel number information to the area on the filter net corresponding to the normal wind wheel number information. The calculation method is to multiply the difference between the two by the angle range value of each area.

Step 602: Rotate the filter according to the rotation angle information and reacquire the wind pressure difference information.

After knowing the rotation angle, the filter is rotated according to the rotation angle information. At this time, the area corresponding to the abnormal wind wheel number information has been aligned with the wind wheel with the normal wind wheel number information. Then the wind pressure difference information is obtained again. It should be noted that at this time, the wind wheel will flap the filter after operating according to steps 200-205.

Step 603: Determine whether the wind pressure difference information begins to decrease.

The purpose of the judgment is to determine whether the abnormality is on the wind wheel or on the filter.

Step 6031: If yes, output the abnormal wind rotor number information and wind rotor damage information.

If it starts to decrease, it means that the blockage features on the filter can be knocked off, which means that the area where the abnormality occurs is on the wind wheel, and the abnormal wind wheel number information and wind wheel damage information are output.

Step 6032: If not, output filter abnormality information.

The filter abnormality information is the information that the filter cannot be cleaned due to the presence of blockage. The output is in the form of text display. If it does not decrease, it means that the wind pressure difference information is on the filter at this time, and the filter abnormality information is output.

It should be noted that the method here is simpler and more effective than using air pressure shock and water flow shock, but it cannot deal with the abnormal effects of the filter; although the previous method is more complicated to handle, it can effectively deal with the results of abnormal filters.

8, a method for cleaning dust and water accumulated between the outer wind shield and the inner wall of the air duct is also included, the method comprising:

Step 700: Obtain the maximum rotation angle information of the outer wind shield.

The maximum rotation angle information is information about the maximum angle that the outer wind shield plate can rotate when rotating toward the wind duct, and is obtained by an angle sensor.

Step 701: Determine whether the maximum rotation angle information is greater than the preset maximum ventilation angle information.

The maximum ventilation angle information is the angle information that allows the wind to completely pass through the filter, that is, at this ventilation angle, the wind passes through the filter normally and the internal and external wind pressure difference is 0. The purpose of the judgment is to determine whether the impurities between the outer wind shield and the air duct affect the normal operation of the outer wind shield.

Step 7011: If greater than, then work normally.

If it is greater, it means that although there are impurities, it does not affect the normal operation of the outer wind shield, so it can work normally.

Step 7012: If it is less than, all numbered outer wind shields are closed with full-closed angle information and all numbered inner wind shields are blocked with full-blocking angle information, and then the fan is driven forward according to the impact power information and impact frequency information to squeeze out the wind and open the drain valve.

When all the numbered outer wind shields are closed at the full-closed angle information and all the numbered inner wind shields are blocked at the full-blocking angle information, the pipe outside the filter is blocked. Then the fan is driven forward according to the impact power information and impact frequency information to form a high-pressure environment when the wind is squeezed out, and finally the drain valve is opened to discharge the impurities between the filter and the outer wind shield from the drain valve. If it is less than, it means that the impurities between the outer wind shield and the air duct need to be discharged.

Step 702: reacquire the maximum rotation angle information of the outer wind shield plate and re-determine whether it is greater than the maximum ventilation angle information.

The purpose of re-acquisition is to determine whether the cleanup is complete.

Step 7021: If yes, close the drain valve and operate normally.

If the maximum angle is greater than the maximum ventilation angle information, it means that it can work normally, then it starts to work normally and closes the drain valve to seal the wall of the air duct.

Step 7022: If not, output an alarm message.

The alarm information is the alarm information that the internal impurities cannot be cleaned and affect the normal operation of the fan. The output method can be any method, such as a red light. If there is no alarm, it means that the internal impurities cannot be automatically discharged by the system, and the staff can be alerted to perform manual cleaning. If necessary, the number of repetitions can also be calculated here to determine the results of multiple cleanings to ensure the accuracy of the results.
