The working process of the anti-blocking alarm system can specifically comprise the following steps:
and the PLC is used for determining a first blocking signal uploaded by the sensor when a probe of the sensor is covered by powdered sugar in the first monitoring area, and determining a second blocking signal uploaded by the visual recognition module when the visual recognition module recognizes that powdered sugar accumulation in the second monitoring area exceeds a set amount.
Specifically, can confirm the position of sensor installation according to the pile volume of powdered sugar among the actual production environment, when powdered sugar covers the probe of sensor, can regard the first monitored area at sensor place to have the jam risk this moment, and powdered sugar covers the probe of sensor and can make the sensor switch-on, and the sensor can be uploaded PLC to the first jam signal that obtains with the switch-on this moment, and then PLC can control the first machine bring to rest of first monitored area.
In addition, because powdered sugar has viscosity and may be adhered to form lumps, in some production line sections with large fall, in order to prevent the powdered sugar from accumulating and sliding down to damage sensors or other equipment, the monitoring area of the type mentioned above can be used as a second monitoring area for monitoring by using a visual identification module. When the powdered sugar accumulation amount of the second monitoring area is identified by the visual identification module to exceed the set amount, the second monitoring area can be considered to have a blocking risk, so that a second blocking signal is uploaded to the PLC, and the PLC can control the second machine of the second monitoring area to stop running.
Specifically, in order to ensure production safety, the operation of the relevant machine can be temporarily stopped when the blockage occurs, and the operation can be carried out after the blockage is eliminated. After the switch receives the first blocking signal or the second blocking signal, the corresponding monitoring area where the blocking occurs can be determined according to the blocking signal, and the machine in the monitoring area is stopped in time, so that the larger loss is avoided.
And the upper computer is used for displaying a blockage alarm prompt according to at least one of the first blockage signal and the second blockage signal.
Specifically, when receiving a first blocking signal or a second blocking signal transmitted by the PLC, the upper computer can display a warning prompt of blocking on a display interface of the upper computer, wherein the warning prompt can comprise a text prompt for a region of blocking or a flashing light and other obvious modes, and timely prompts a detector to have the region of blocking and rapidly process the region.
Further, a plurality of sensors can be provided, and in the embodiment of the invention, two sensors are taken as an example, the two sensors are respectively installed in the first monitoring area, the feeding area and the discharging area of powdered sugar, when a first probe in the feeding area of the first monitoring area is covered by powdered sugar, a feeding area blocking signal can be uploaded to the PLC, and when a second probe in the discharging area of the first monitoring area is covered by powdered sugar, a discharging area blocking signal can be uploaded to the PLC.
In order to reduce the blocking risk of the second monitoring area, the vision recognition module can shoot real-time images of the second monitoring area according to a set time interval, and recognize whether powdered sugar of the second monitoring area in the real-time images exceeds a set amount, when the second monitoring area is blocked, the vision recognition module uploads a second blocking signal to the PLC, the PLC can control the vibrating conveyor, the bucket elevator and the screw conveyor to stop running according to the second blocking signal, and secondary accidents are avoided.
In order to help the detection personnel to check the blocking condition more clearly, the visual identification module in the embodiment of the invention can also shoot a real-time video for the second monitoring area when the powdered sugar accumulation in the second monitoring area is identified to exceed the set amount, the visual identification module can upload the real-time video to the upper computer through the switch, and the upper computer can watch the specific situation of the site in real time.

step S110: and controlling a first machine of the first monitoring area to stop running according to the first jam signal, or controlling a second machine of the second monitoring area to stop running according to the second jam signal.
For a specific implementation process, reference may be made to the description of the foregoing embodiments, which are not described herein again.
The following describes an implementation of the anti-jamming alarm of the present invention with specific examples, and specifically refers to fig. 3 and 4 and the following description.
Fig. 3 is a scene schematic diagram of an application example of an anti-clogging alarm system provided by the present invention, and fig. 4 is a system framework diagram of the anti-clogging alarm system provided by the present invention.
An anti-jamming alarm system of an embodiment of the present invention may include: host computer (wincc), switch, plc controller, capacitanc inductive switch, vision AI system, camera.
The host computer can monitor the operation of jam alarm system, can realize the control of universe, accepts the alarm information of jam alarm system. The sensor normally displays green color, senses the occurrence of blockage and displays red alarm on the interface. Visual system can be through camera control fixed area, and normal conditions is lower than the background operation, when detecting the jam, sends out the police dispatch newspaper, through blockking up alarm system linkage production industrial control system, stops upstream equipment operation, and the on-the-spot video can be popped out to the host computer simultaneously, the picture, the jam scene of looking over directly perceived, raise the efficiency.
The switch can realize the communication between the blockage alarm system and an upper computer (wincc) and other industrial control systems for production, the blockage alarm signal transmits the alarm signal to the upper computer (wincc) and other industrial control systems through Ethernet, so that the conveying equipment in linkage production is controlled to start and stop through reasonable logic under the condition of blockage, the equipment is protected, and the time and the workload of personnel for processing materials scattered on a production site are reduced.
If the bucket elevator breaks down, the sugar cannot be conveyed to the vibration conveyor at a high position through the bucket, and the sugar is accumulated in the area A, so that the sugar can be stuck and burnt by the motor of the bucket elevator after a long time, and the machine is damaged. And a capacitive solid sensor is arranged in the area A, if the white granulated sugar in the area A is accumulated to trigger alarm, the blocking system uploads an alarm signal to an interface of an upper computer to display red, and meanwhile, the signal is transmitted to an industrial control system to control the screw conveyor to stop.
If the drive belt of the vibrating conveyor falls off, sugar is accumulated in the area of the pipeline B and finally falls into the area A, and the fault damage of the bucket elevator can also be caused. Therefore, a capacitive solid sensor is installed in the area B, white granulated sugar is accumulated to trigger alarm, the blocking system uploads an alarm signal to an interface of an upper computer to display red color, and meanwhile, the signal is transmitted to an industrial control system to control the screw conveyor and the bucket elevator to stop.
If the belt feeder off tracking, lead to the unable transport of sugar, the white granulated sugar is piled up C region through the pipeline, spill over ground D district even, because the pipeline is perpendicular, the white granulated sugar damages the sensor to capacitanc solid sensor friction easily, consequently install the camera here, a picture is taken every interval 1 minute to the camera, visual system judges here through picture AI mode whether to take place to block up, if take place to block up, send alarm signal to blocking up alarm system, alarm system sends alarm signal to the host computer again, open the video at visual system simultaneously, look over the condition of confirming the scene, send alarm signal to industrial control system in addition, control vibration conveyer, bucket elevator and screw conveyer shut down.
The vision AI system is a small-sized industrial computer, carries a CPU, an internal memory, runs a Linux operating system, configures a USB port for connecting a camera, configures an input/output IO point, is used for outputting an image judgment result, namely outputting an alarm signal, configures a network protocol of a network port TCP, and can remotely call the camera image. The operating system is provided with an artificial intelligence software library, a machine vision software library and the like.
Before the system is started, a normal state picture and a picture with a white granulated sugar accumulation state which are marked in the area C and the area D are used for training an artificial intelligence recognition model.
Normal state of CD area: the white granulated sugar appeared in the picture is very little.
State of CD area stacking: a large amount of white granulated sugar appears in the picture.
During training, two data sets are generally divided, one is a training set (70 percent) and the other is a verification set (30 percent).
And then, running a script program to realize that a camera is used for capturing a scene picture every 1 minute, calling a trained artificial intelligence recognition model for judgment, setting an output IO point position in the model to be 1 if white granulated sugar is accumulated, and connecting the signal to an input point DI of the PLC to serve as an alarm signal of the visual AI. The PLC receives the signal and transmits the signal to the upper computer. And sending out a sparkling warning by the winc interface of the upper computer. The upper computer runs a script file at the same time, after receiving the alarm signal of the PLC, the interface of the camera is automatically popped up, and an operator can directly observe the field condition through the interface video of the camera.
The artificial intelligence recognition model can be simply understood as a mathematical formula: y = f (X). The training of the model, i.e. the validation of the parameter a, finds a mathematical function f (x). The CD picture labeled "pile up", understood as x1, is input to the model, at which point the result of the operation is y1; the CD area labeled "Normal", understood as x2, is entered into the model, where the result is y2; through a certain number of training pictures, a "pile-up" constant Y1 and a "normal" constant Y2 are identified.
When the artificial intelligence recognition model is called, a newly-captured picture input into the model is equivalent to x0, a calculated Y0 value is obtained, when Y0 is within a certain range of a 'stacking' constant Y1, the picture x0 is judged to be stacked, and an output IO point is set to be 1 and serves as an alarm signal; and when the y0 is within a certain range of the normal constant, judging that the picture x0 is normal.
