Description

Unique information setting system and unique information setting device

technical field

The present invention relates to an inherent information setting system and an inherent information setting device. In the inherent information setting system, the inherent information setting device sets inherent information such as addresses for management and various parameters for wireless equipment through wireless communication. the

Background technique

Currently, equipment used to control air conditioners in buildings (for example, controllers, sensors, and actuators) is moving toward wireless for ease of construction. In order to operate the air-conditioning control system, it is necessary to set specific information such as addresses for management and various parameters in these wireless devices (hereinafter referred to as wireless devices). the

In the prior art, there are the following two ways of setting intrinsic information for wireless devices. the

(1) Set a switch for setting inherent information on the wireless device;

(2) Connect the unique information setting device and the wireless device with a communication line, and write the unique information into the nonvolatile memory inside the wireless device by operating the unique information setting device connected with the communication line. the

When the method (1) is adopted, a switch and a reading circuit need to be provided. When adopting the method (2), it is necessary to install a wired communication circuit connected to the unique information setting device. In addition, regardless of the method (1) or the method (2), when setting unique information to a wireless device installed in a ceiling, etc., it is necessary to use a ladder or the like to approach the wireless device. Therefore, this setting work is troublesome and time-consuming. Although it is also possible to set the management address of the wireless device before installing the wireless device, even in this case, when the unique information changes, it is still necessary to use a ladder or the like to approach the wireless device. the

In view of this, if the unique information is set for the wireless device by the unique information setting device and the wireless communication method, the unique information of the wireless device can be set without using a ladder or the like to approach the wireless device, and the setting operation is relatively simple. As described in Patent Document 1: a wireless address setter (proper information setting device) is used to set an address (proper information) to a terminal (wireless device) installed at the work site through a wireless communication method. Hereinafter, the form described in this patent document 1 is called form (3). the

According to the method (3), when using the wireless address setting device, it is necessary to input the physical identification code (identification information) of each terminal device and the address assigned to the terminal device through the operation part for setting. Therefore, the corresponding relationship between the physical identification code of each terminal machine and the address allocated to the terminal machine needs to be input in the wireless address setting device. When setting an address for a terminal, the wireless address setting device is carried to a place where a desired terminator is installed, and the physical identification code is input to the terminal through the operating part for setting. At this time, the signal transmission and reception unit of the wireless address writer faces the signal transmission and reception unit of the terminal device. Thus, the address corresponding to the input physical identification code is read and sent to the desired terminal. Thus, the address corresponding to the physical identification code of the terminal set in the wireless address setting device is set in the terminal. the

Patent Document 1: Japanese Invention Patent Laid-Open Gazette, Japanese Patent Application Laid-Open No. 8-140169

However, when the method (3) is adopted, the corresponding relationship between the identification code of each terminal and the address assigned to the terminal needs to be input into the wireless address setting device in advance, so the input operation is cumbersome. the

In addition, the method (3) is based on the premise that the installation location of the terminal has been determined. If the installation location of the terminal is uncertain, it is difficult to set an address for the terminal. the

In addition, when the method (3) is adopted, if there are multiple terminal machines within the communication range of the wireless address setting device, the address of the desired terminal machine may be set in other terminal machines. the

Contents of the invention

The present invention was made to solve the above problems, and an object of the present invention is to provide a unique information setting system and a unique information setting device. By adopting the present invention, there is no need to input the corresponding relationship between the identification code of each wireless device and the inherent information assigned to the wireless device into the inherent information setting device, and even if you do not know the installation position of the wireless device, you can find the required information. wireless devices, and the management address can be correctly set only for the required wireless devices. the

In order to achieve the above object, the present invention provides a unique information setting system, which has a wireless device and a unique information setting device. The setting device includes: a layout drawing display mechanism for displaying the layout drawing of the specified area; a loopback instruction sending mechanism, in the layout drawing displayed by the layout drawing display mechanism, when the current position of the inherent information setting device is used as the measurement location When the measurement is started, the loopback instruction sending mechanism sends a loopback instruction to the wireless device within the communication range, instructing the wireless device to send back the identification information provided therein; the measurement result storage mechanism, the wireless device sends back the identification information according to the loopback instruction, the said The measurement result storage means stores the received identification information and the signal strength at the time of receiving the identification information as a pair of measurement results measured at the measurement location; For the stored measurement results of at least three different measurement locations, for each identification information contained in the measurement results, determine the position of each wireless device that sent back the identification information, and determine the position of the wireless device after the position is determined. The location is shown in the layout diagram; the wireless device includes: an identification information return mechanism, which returns the identification information set in the wireless device to the inherent information according to the identification information return instruction sent by the inherent information setting device. in the information setting device. Besides the inherent information setting system, the present invention also provides an inherent information setting device. the

According to the present invention, for example, if it is desired to set unique information such as management addresses and parameters for wireless equipment installed on a floor, a floor layout is displayed on the screen of the unique information setting device. Next, the measurement is started using the current position of the inherent information setting device on the first floor as the first measurement point. Next, the inherent information setting device sends an identification information return instruction to the wireless equipment within the communication range, requesting the wireless equipment to return the internally set identification information. The wireless equipment within the communication range returns the identification information set inside it to the inherent information setting device according to the identification information return instruction sent by the inherent information setting device. The identification information at this time is information that can distinguish wireless devices such as product serial numbers. When a wireless device within the communication range sends back identification information, the inherent information setting device stores the returned pair of identification information and the signal strength when receiving the identification information as the measurement result measured at the first measurement point. the

Next, the measurement point is changed within one floor, and the measurement is started using the current position of the unique information setting device after the position change as the second measurement point. Next, the inherent information setting device sends an identification information return instruction to the wireless equipment within the communication range, requesting the wireless equipment to return the internally set identification information. The wireless equipment within the communication range returns the identification information set inside it to the inherent information setting device according to the identification information return instruction sent by the inherent information setting device. When a wireless device within the communication range sends back identification information, the inherent information setting device stores the returned pair of identification information and the signal strength when receiving the identification information as the measurement results measured at the second measurement location. the

Next, the measurement point is changed again within one floor, and the measurement is started using the current position of the unique information setting device after the position change as the third measurement point. Next, the inherent information setting device sends an identification information return instruction to the wireless equipment within the communication range, requesting the wireless equipment to return the internally set identification information. The wireless equipment within the communication range returns the identification information set inside it to the inherent information setting device according to the identification information return instruction sent by the inherent information setting device. When a wireless device within the communication range sends back identification information, the inherent information setting device stores the returned pair of identification information and the signal strength when receiving the identification information as the measurement result measured at the third measurement location. the

Thus, in the present invention, at least three different measurement locations receive the identification information sent back by the wireless devices within the communication range, and each pair of identification information sent back and the signal strength when receiving the identification information are used as measurements at each measurement location. The measurement results are stored. At this time, for example, there are three different measurement locations, and when the measurement results measured at the three different measurement locations are stored, the loopback can be determined according to algorithms such as triangulation for each identification information contained in the measurement results. The location of the wireless device that has the identifying information. the

That is, the distance between the wireless device that sent back the identification information and each measurement point can be estimated based on the signal strength when receiving the identification information, and the wireless device that sent back the identification information can be determined by using the estimated distance and algorithms such as triangulation. The location of the wireless device. In the present invention, the number of measurement locations can also be increased to improve the positioning accuracy of the wireless device. The present invention determines the position of the wireless device in the above manner, and displays the determined position of the wireless device in the layout diagram. Thus, even if the location of the wireless device is uncertain, the desired wireless device can be found. the

In the present invention, a setting information input unit display mechanism may also be provided in the inherent information setting device. When the slave position has been determined and displayed in the wireless device in the layout diagram, the desired wireless device is designated as the setting. When the target is set, the setting information input unit display unit displays an input unit for inputting setting information with respect to the specified wireless device as a setting target. the

For example, the location of wireless devices A, B, C has been determined and shown in a layout diagram. When the wireless device A is designated as a setting object among these wireless devices, the setting information input unit display means displays an input unit for inputting setting information to the wireless device A. In this case, the input unit for the setting information of the wireless device A is, for example, one that obtains a default value of the setting information from the storage unit of the actual wireless device A and displays various setting information including the default value. An input window; or, the default value of the setting information corresponding to the type of the wireless device A is obtained from the storage unit of the specific information setting device, and an input window of various setting information including the default value is displayed. the

In this way, it is possible to designate a desired wireless device as a setting target from among the wireless devices displayed on the floor plan, and then display an input section for inputting setting information for the wireless device as a setting target. The fixed information input unit inputs necessary setting information (unique information) to a wireless device to be set. the

In addition, in the present invention, a setting information sending mechanism may be provided in the unique information setting device. The setting information sending mechanism sends the identification information of the wireless device as the setting object together with the determined setting information to the wireless devices within the communication range. In addition, the present invention can also be provided with an inherent information storage mechanism in the wireless device. When the identification information sent together with the setting information is consistent with the identification information set inside a certain wireless device, the inherent information storage mechanism The setting information is then stored as inherent information assigned to the wireless device. the

For example, wireless device A is designated as the setting object, the required setting information is input into the input part of the setting information of the wireless device A, and the input of the setting information is confirmed (that is, the confirmation button is clicked to confirm the input). the setting information). At this time, the unique information setting device transmits the identification information of the wireless device A together with the determined setting information to the wireless devices within the communication range. At this time, since the identification information "#1" sent together with the setting information sent by the unique information setting device matches the identification information "#1" of the wireless device A, the wireless device A within the communication range will set the setting information. Information is stored as inherent information assigned to itself. Thereby, unique information can be correctly set only for the wireless device to be set.

In this embodiment, the wireless device (wireless device to be set) for which specific information needs to be set is set as the wireless device 1-2. the

[Step 1: Display of layout plan] 

The operator activates the specific information setting device 2 to display a floor layout of the first floor (hereinafter, simply referred to as "floor layout") on the display 2-8 (arrow (1) in FIG. 4 ). Figure 5 illustrates a floor plan in displays 2-8. As shown in the figure, the floor plan G1, the measurement start button BT1, the determination button BT2, the message display column MS, the measurement point input column PW, etc. are displayed on the display 2-8. the

The measurement results of the first measurement point PA measurement are stored. Next, the user is notified through the message display column MS that the measurement at the first measurement location PA has ended. the

[Step 3: Measurement at the second measurement location] 

Next, the operator changes the measurement location on the 1st floor. At this time, an arbitrary position apart from the first measurement point PA is set as the second measurement point PB, and the inherent information setting device 2 is moved to the second measurement point PB. Next, the position of the second measurement point PB is marked on the floor plan G1 (arrow (5) in FIG. 4 ). Thus, as shown in FIG. 7 , the position mark MB of the second measurement point PB is displayed in the floor plan G1 . the

Next, the operator inputs "site PB" in the measurement site input column PW, and clicks the measurement start button BT1 with the mouse. Then, the inherent information setting device 2 transmits the physical identification code echo command to the wireless devices 1 (1-1, 1-2, 1-3) within its communication range (arrow (6) in FIG. 4 ). According to the physical identification code feedback command issued by the inherent information setting device 2, the wireless equipment 1-1, 1-2, 1-3 within the communication range will send the physical identification codes "#1" and "#" set inside it. 2", "#3" are returned to the unique information setting device 2 (arrow (7) in FIG. 4). the

Next, the user is notified through the message display column MS that the measurement at the second measurement location PB has ended. the

[Step 4: Measurement at the third measurement location] 

Next, the operator changes the measurement location on the 1st floor again. At this time, an arbitrary position away from the first measurement point PA and the second measurement point PB is set as the third measurement point PC, and the inherent information setting device 2 is moved to the third measurement point PC. Next, the position of the third measurement point PC is marked on the floor plan G1 (arrow (8) in FIG. 4 ). Thus, as shown in FIG. 8, the position mark MC of the third measurement point PC is displayed in the floor plan G1. the

Next, the operator inputs "site PC" in the measurement site input column PW, and clicks the measurement start button BT1 with the mouse. Then, the inherent information setting device 2 transmits a physical identification code echo command to the wireless devices 1 (1-1, 1-2, 1-3) within its communication range (arrow (9) in FIG. 4 ). According to the physical identification code feedback command issued by the inherent information setting device 2, the wireless equipment 1-1, 1-2, 1-3 within the communication range will send the physical identification codes "#1" and "#" set inside it. 2", "#3" are returned to the unique information setting device 2 (arrow (10) in FIG. 4). the

When the wireless devices 1-1, 1-2, 1-3 within the communication range return their physical identification codes "#1", "#2", and "#3" to the inherent information setting device 2, the inherent information The setting device 2 measures the radio wave strength (signal strength) V1C, V2C, V3C when receiving the physical identification codes "#1", "#2", and "#3", and uses the physical identification code "#1" and signal strength V1C as a pair; physical identification code "#2" and signal strength V2C as a pair; physical identification code "#3" and signal strength V3C as a pair, each pair of physical identification code and signal strength as The results of the PC measurement at the third measurement location are stored. Next, the user is notified through the message display column MS that the measurement at the third measurement location PC has ended. the

[Step 5: Determine the location of the wireless device] 

When the measurement at the third measurement location PC is completed, the inherent information setting device 2 automatically sets the physical identification code "#1" included in the measurement results according to the measurement results at the measurement locations PA, PB, and PC. , "#2", "#3", respectively to determine the position of the wireless device 1-1, 1-2, 1-3 that has returned the physical identification code, and the wireless device 1-1, 1-2 , 1-3 are shown in the floor plan G1 (arrow (11) in Fig. 4). FIG. 9 shows the positions of the wireless devices 1-1, 1-2, 1-3 shown in the floor plan G1. The positions of the wireless devices 1-1, 1-2, 1-3 are denoted by marks M1, M2, M3, respectively. the

At this time, the position of the wireless device 1 - 1 that sent back the physical identification code "#1" is specified, for example, as follows. For the physical identification code "#1", the signal strength V1A measured at the first measurement point PA, the signal strength V1B measured at the second measurement point PB, and the signal strength V1C measured at the third measurement point PC are stored. From the signal strengths V1A, V1B, V1C, the distances R1A, R1B, and R1C between the wireless device 1 - 1 that sent back the physical identification code "#1" and the measurement points PA, PB, and PC are estimated. the

Next, the position of the wireless device 1-1 is determined using the estimated distances R1A, R1B, and R1C according to an algorithm such as triangulation (see FIG. 10 ). Next, the same method is used to determine the positions of the wireless device 1-2 which sent back the physical identification code "#2" and the wireless device 1-3 which sent back the physical identification code "#3". the

[Step 6: Designation of wireless devices to be set up] 

The operator designates a desired wireless device as a setting object from among the wireless devices 1-1, 1-2, 1-3 whose positions have been displayed on the floor plan G1. In this embodiment, the wireless device 1-2 is designated as the setting object, and the position mark M2 of the wireless device 1-2 is clicked with the mouse (arrow (12) in FIG. 4 ). When the mark M2 is clicked with the mouse, the color of the mark M2 will change. the

[Step 7: Obtain the default value of the setting information from the wireless device targeted for setting] 

Next, the inherent information setting device 2 sends a signal for sending the default value of the setting information to the wireless devices 1 (1-1~1-3) within the communication range: that is, it requests the wireless devices 1 (1-1~1-3) ) to send the default value of its setting information. At the same time, it also sends the physical identification code "#2" of the wireless device 1-2 as the setting object to the wireless device 1 (1-1～1-2) along with the signal. 3) (arrow (13) in Fig. 4). the

The wireless devices 1 (1-1 to 1-3) within the communication range receive a signal from the inherent information setting device 2 to send the default value of the setting information, and judge whether the physical identification code "#2" sent together with the signal is It is consistent with the physical identification code set inside it. the

At this time, the wireless device 1-2 as the setting object judges that the physical identification code "#2" transmitted with this signal matches the identification code set inside it. As a result, the wireless device 1-2 as the setting object transmits the signal of the default value of the setting information sent by the inherent information setting device 2, and the various setting information items stored in it and the setting information items contained in the setting information item The default value of the corresponding setting information is sent back to the inherent information setting device 2 (arrow (14) in FIG. 4 ). the

The inherent information setting device 2 obtains the returned various setting information items and the default value of the setting information corresponding to the setting information item from the wireless device 1-2 as the setting object, and sets each setting information including the default value.
