Description

  The present invention relates to a management address setting method and system for a wireless device that sets a management address by wireless communication from a management address setting device to the wireless device.

For the purpose of simplifying the construction, etc., building air conditioning control devices (for example, controllers, sensors, actuators) are becoming wireless. It is necessary to set a management address for these wireless devices to function as an air conditioning control system.
As a method for setting a management address for this wireless device,
(1) Method of providing a management address setting switch in a wireless device (2) The management address setting device is connected to the wireless device with a communication line, and the operation of the management address setting device via the communication line allows the nonvolatile in the wireless device There is a method to write the management address to the memory.

  In the method (1) described above, a switch and a reading circuit are required, and in the method (2) described above, a wired communication circuit with a management address setting device is required. In addition, in both methods (1) and (2), when setting a management address for a wireless device installed on the ceiling or the like, it is necessary to approach the wireless device using a ladder or the like. Is cumbersome and time consuming. Even if the management address is set before installation, if the management address is changed, it is necessary to use a ladder or the like to approach the wireless device.

  On the other hand, if the management address is set for the wireless device by wireless communication from the management address setting device, it is not necessary to approach the wireless device using a ladder or the like, and the setting work is simplified. For example, in Patent Document 1, a wireless address setting device (management address setting device) is used to set an address (management address) to a terminal device (wireless device) installed in the field by wireless communication. . Hereinafter, the system disclosed in Patent Document 1 is referred to as system (3).

  In method (3), when using a wireless address setting device, an identifier of each terminal device and an address assigned to the terminal device are input in advance through the setting operation unit. Thereby, the correspondence between the identifier of each terminal and the address assigned to the terminal is registered in the wireless address setting device. When setting an address for a terminal, take the wireless address setter where the desired terminal is installed and use the terminal's identifier instead of the abstract and confusing address of the terminal. Is input via the selection operation unit. At this time, the transmitter / receiver of the wireless address setter is directed to the transmitter / receiver of the desired terminal. Then, an address corresponding to the input identifier is read out and sent to a desired terminal. Thereby, an address registered in association with the identifier of the terminal is set in the desired terminal.

JP-A-8-140169

However, in the above-described method (3), the correspondence relationship between the identifier of each terminal and the address assigned to the terminal must be registered in advance in the wireless address setter, and the registration work for this is troublesome. .
Further, in the method (3) described above, it is premised that the installation location of the terminal is clearly known, and it is difficult to set an address when the installation location of the terminal is unclear.
In the method (3) described above, when a plurality of terminals are mixed within the communication range of the wireless address setter, there is a possibility that the address for the desired terminal is set to another terminal. It was.

  The present invention has been made to solve such a problem, and the object of the present invention is to pre-register the correspondence between the identifier of each wireless device and the management address assigned to the wireless device in the management address setting device. Even if the installation location of the wireless device is not clear, it is possible to find a desired wireless device and set a management address correctly only for the wireless device. Is to provide.

In order to achieve such an object, the present invention allows a management address setting device to specify a partner in a management address setting method for a wireless device that sets a management address for the wireless device by wireless communication from a management address setting device. First, as the desired transmission radio field strength selected and specified from multiple types of transmission radio field strengths, the model of the wireless device for which the management address is desired is selected and specified from a plurality of predetermined model types. As a desired model, a first step of transmitting a return command of identification information preset in each wireless device to each wireless device, and a wireless within a communicable area that has returned the identification information in response to the return command The second step of creating a list of devices in the management address setting device and the identification information of the wireless device selected and designated from the list of wireless devices in the communicable area that returned the identification information The third step of transmitting to each wireless device without identifying the other party from the address setting device, and the location of the wireless device in which the identification information matching the identification information transmitted from the management address setting device is set The management address designated for the desired wireless device in the list of wireless devices in the communicable area that returned the identification information together with the identification information of the wireless device from the management address setting device. 5th step transmitted to the wireless device, and the management address transmitted together with the identification information in the wireless device in the communicable area where the identification information matching the identification information transmitted from the management address setting device is set Is stored as a management address assigned to itself. Note that the present invention can be realized not only as a management address setting method for a wireless device but also as a management address setting system for a wireless device.

In the present invention, the management address setting device specifies a transmission address intensity of a wireless device that desires to set a management address as a desired transmission signal intensity selected and specified from a plurality of predetermined types without specifying a partner . As a desired model selected and specified from a plurality of models determined in advance, an identification information return command set for the wireless device is transmitted to each wireless device. For example, a desired transmission radio wave intensity selected and specified from a plurality of types is set to “weak”, and a desired model selected and specified from a plurality of models is set to “a”. Send a return command for the identification information. In this case, the wireless device A and the wireless device B of the model “a” are within the communicable range with the transmission field strength “weak” of the management address setting device, and the identification information # 1 is preset in the wireless device A. When the identification information # 2 is set in advance in the wireless device B, the wireless devices A and B receive the identification information return command transmitted by the management address setting device, and the respective identification information # 1 and # Return 2

  When the identification information # 1 and # 2 are returned from the wireless devices A and B, the management address setting device creates a list of the wireless devices A and B that have returned the identification information # 1 and # 2. For example, identification information # 1 and # 2 are displayed on the screen as a list of wireless devices that have returned identification information. It is not always necessary to display the identification information on the screen, and the wireless device that has returned the identification information may be displayed with a temporary number or an icon (pictogram) may be displayed. . If, for example, wireless device A is selected and specified from the list of wireless devices that have returned this identification information, identification information # 1 of wireless device A does not identify the partner from the management address setting device, and each wireless device is identified. Sent. Here, only the wireless device A in the communicable area is informed of the presence of the self because the identification information # 1 transmitted from the management address setting device matches the identification information # 1 set in advance in itself. . For example, the presence of oneself is notified by sounding a buzzer, or the presence of oneself is notified by turning on a lamp. If the wireless device is an air-conditioning control device, the presence of itself may be notified by a function inherent to the device, for example, a method of blowing out wind by starting a fan.

  When the wireless device A that has notified the presence of the wireless device A is not the desired wireless device, the operator selects and designates the wireless device B from the list of wireless devices that have returned the identification information. Then, the identification information # 2 of the wireless device B is transmitted to each wireless device without specifying the other party from the management address setting device. Here, only the wireless device B in the communicable area is informed of its existence because the identification information # 2 transmitted from the management address setting device matches the identification information # 2 set in advance in itself. .

  When the wireless device B that has notified the presence of itself is the desired wireless device, the operator designates a management address for the wireless device B in the list of wireless devices that have returned the identification information. For example, the address AD2 is designated as the management address. Then, the management address setting device transmits the designated management address AD2 to each wireless device together with the identification information # 2 of the wireless device B. Here, since only the wireless device B within the communicable area has the identification information # 2 transmitted from the management address setting device and its own identification information # 2, the management address AD2 transmitted together with the identification information. Is stored as the management address assigned to itself.

According to the present invention, a wireless device that wishes to set a management address as a desired transmission radio wave intensity selected and designated from a plurality of predetermined types without specifying a partner from a management address setting device. As a desired model selected and specified from a plurality of predetermined models, an identification information return command set in advance for each wireless device is transmitted to each wireless device, and this return command is answered. The management address setter creates a list of wireless devices that have returned identification information, and the identification information of the wireless device selected and specified from the list is not specified by the management address setter for each wireless device. transmitted, since the identification information matching the identification information transmitted from the management address setter is adapted to broadcast its own location in a wireless device that is set in advance, down the number of wireless devices to respond After having a thing, even if the location of the wireless device is unclear, select the wireless device from the list of wireless devices to request the return of the identification information about the wireless devices, has returned the identification information It is possible to search for a desired wireless device while designating it and set a management address for the wireless device.

  Further, according to the present invention, the management address designated for the desired wireless device in the list of wireless devices that have returned the identification information is sent to each wireless device from the management address setting unit together with the identification information of the wireless device. The management address is stored as the management address assigned to itself in the wireless device in which the identification information that matches the transmitted identification information is set in advance. Correspondence between the identifier and the management address assigned to the wireless device need not be registered in advance, and troublesome registration work is not required. In addition, since the management address is stored in the wireless device after confirming that the identification information matches, even if there are multiple wireless devices in the communicable area of the management address setting device, only the desired wireless device can be used. The management address can be set correctly.

It has a model selection function that can be specified .

[Management address setting]
The processing operation according to the management address setting program executed by the wireless device 1 (CPU 1A) and the management address setting device 2 (CPU 2-1) will be described below with reference to the sequence diagram shown in FIG. In this example, a desired wireless device 1 for which a management address is to be set is a wireless device 1-2.
[Procedure 1]
The operator activates the management address setting device 2 at a place where the desired wireless device 1-2 is considered to be installed. Here, in order to reduce the number of responding wireless devices 1, the transmission radio wave intensity is set to “weak”, and the wireless device model for which the management address is desired to be set is set to “a”. FIG. 5 shows a display screen example in the management address setting device 2. In this case, “weak” is selected and designated in the transmission radio wave intensity selection unit BL1 at the top of the screen. In addition, “a ***” is selected and specified in the model selection section BL2 at the top of the screen.

[Procedure 2]
Then, the operator clicks the transmission button BT1 in the identification code return command unit BL3 on the screen (FIG. 4A). Then, the management address setting device 2 returns the identification code to each wireless device 1 without specifying the other party with the transmission radio wave intensity set to “weak” and the model of the wireless device to which the identification code is desired to be returned “a”. A command is transmitted (FIG. 4B). In this example, it is assumed that the wireless devices 1-1 to 1-6 are located within the communicable area of the management address setting device 2 as shown in FIG.

  When the wireless device 1 (1-1 to 1-6) in the communicable area receives the identification code return command from the management address setting device 2, it is the model “a” for which it is desired to return the identification code. Check whether or not. In this case, since the wireless devices 1-1 to 1-5 are the model “a” and the wireless device 1-6 is the model “b”, the wireless devices 1-1 to 1-5 of the model “a” identify themselves. The code is returned to the management address setting device 2 (FIG. 4C). In addition, in response to each identification code return command that does not specify the other party, it is known that a plurality of wireless devices 1 return identification codes while avoiding collisions, or detect and retransmit collisions. Is possible.

  The management address setting device 2 displays a list of identification codes returned from the wireless devices 1-1 to 1-5 on the identification code selection unit BL4 in the screen (FIG. 4 (d)). In this example, the received radio wave intensity is checked, and the identification codes are arranged and displayed from the top in descending order of the received radio wave intensity. Corresponding to the identification code, the received radio wave intensity (strong, medium, weak) is displayed. As a result, the wireless device closer to the management address setting device 2 displays its identification code at the upper level. This list of identification codes corresponds to the “list of wireless devices that have returned identification information” in the present invention. Instead of the identification code, the wireless device that has returned the identification code may be displayed with a temporary number or an icon (pictogram) may be displayed.

[Procedure 3]
The operator selects and designates, for example, the wireless device indicated by the highest identification code “a1234” in the list of identification codes of the identification code selection unit BL4 (FIG. 4E). In this case, as shown in FIG. 6A, the identification code selection button PA1 displayed corresponding to the identification code “a1234” of the identification code selection unit BL4 is clicked. Then, the management address setting device 2 transmits the identification code “a1234” to each wireless device 1 without specifying the other party (FIG. 4F).

  When the wireless device 1 (1-1 to 1-6) within the communicable area receives the identification code “a1234” from the management address setting device 2, whether or not the identification code “a1234” matches its own identification code. To check. In this case, the identification code “a1234” is set in advance in the wireless device 1-1 and matches the identification code “a1234” transmitted from the management address setting device 2. When the wireless device 1-1 confirms that the identification code “a1234” from the management address setting device 2 matches its own identification code “a1234”, the wireless device 1-1 rings the buzzer 1H (FIG. 4G). Announce the whereabouts. In this case, the operator determines that the wireless device 1-1 is not a desired wireless device from the location where the buzzer sounds.

  In this example, the buzzer 1H is sounded, but the lamp 1I may be turned on, and the location of the user may be notified by both the sounding of the buzzer 1H and the lighting of the lamp 1I. . Further, the buzzer may be stopped by an operation from the management address setting device 2 or may be stopped when a certain time has elapsed after the start of the sound. Further, the buzzer may be intermittent sounding instead of continuous sounding. Intermittent ringing makes it easier to grasp the ringing position over the ceiling. Further, the tone, pitch, intermittent ringing pattern, etc. may be set from the management address setting unit 2 side so as not to be confused with ringing sounds by other workers in the vicinity. In addition, you may alert | report presence of the self by the method of blowing out wind by the function of the air-conditioning control apparatus original function, for example, starting of a fan.

[Procedure 4]
Next, the operator selects and designates the wireless device indicated by the next identification code “a2345” in the list of identification codes of the identification code selection unit BL4 (FIG. 4 (h)). In this case, as shown in FIG. 6B, the identification code selection button PA2 displayed corresponding to the identification code “a2345” of the identification code selection unit BL4 is clicked. Then, the management address setting device 2 transmits the identification code “a2345” to each wireless device 1 without specifying the other party (FIG. 4 (i)).

  When the wireless device 1 (1-1 to 1-6) within the communicable area receives the identification code “a2345” from the management address setting device 2, whether or not the identification code “a2345” matches its own identification code. To check. In this case, the identification code “a2345” is preset in the wireless device 1-2 and matches the identification code “a2345” transmitted from the management address setting device 2. When the wireless device 1-2 confirms that the identification code “a2345” from the management address setting device 2 matches its own identification code “a2345”, the wireless device 1-2 sounds the buzzer 1H (FIG. 4 (j)). Announce the whereabouts. In this case, the operator determines that the wireless device 1-2 is a desired wireless device from the location where the buzzer sounds.

[Procedure 5]
When the operator determines that the wireless device 1-2 is the desired wireless device from the location where the buzzer rings, the wireless device 1-2 is displayed in the management address designating unit BL5 displayed on the screen of the management address setting device 2. Select and specify the management address you want to assign to. In this case, “003”, “004”, “005”, and “007” remain as management addresses that can be assigned in the management address designating part BL5. If, for example, “003” is to be assigned as a management address, the management address designation button PB1 corresponding to the management address “003” is clicked (FIG. 7, FIG. 4 (k)).

Then, the management address setting device 2 is selected and specified by the management address specifying unit BL5 and the identification code “a2345” of the wireless device being selected and specified (FIG. 6B) in the list of identification codes of the identification code selecting unit BL4. management addresses "003", ie, the identification with the code "a2345" of the wireless device to "003" specified management address for the desired wireless devices in the list of wireless devices which have returned the identification code, the wireless device 1 (FIG. 4 (l)).

  The wireless devices 1 (1-1 to 1-6) in the communicable area confirm whether or not the identification code “a2345” transmitted from the management address setting unit 2 matches the own identification code. In this case, the identification code “a2345” is preset in the wireless device 1-2 and matches the identification code “a2345” transmitted from the management address setting device 2.

  When the wireless device 1-2 confirms that the identification code “a2345” from the management address setting device 2 matches its own identification code “a2345”, the wireless device 1-2 changes the management address “003” sent together with the identification information. Extracted and stored as a management address assigned to itself (stored in the non-volatile memory 1D). After setting the management address, a confirmation response is returned to the management address setting device 2 (FIG. 4 (m)). Upon receiving the confirmation response from the wireless device 1-2, the management address setting unit 2 updates the management address assignment display in the management address designating unit BL5 from “not yet” to “done”.

As can be seen from the above description, according to the present embodiment, even when the installation location of the wireless device is unclear, it has requested the surrounding wireless device to return the identification code and has returned the identification code. A desired wireless device can be found while selecting and specifying a wireless device from the list of wireless devices, and a management address can be set for the wireless device.
Further, the correspondence relationship between the identifier of each wireless device and the management address assigned to the wireless device does not have to be registered in advance in the management address setting device, and troublesome registration work is not required. In addition, since the management address is stored in the wireless device after confirming the match of the identification code, even if there are multiple wireless devices in the communicable area of the management address setting device, only the desired wireless device The management address can be set correctly.

  In this embodiment, the wireless devices are sequentially selected and specified from the list of wireless devices that returned the identification code (list of identification codes), but the sequential selection and specification of the wireless devices is not necessarily performed by the operator. May be. For example, a function for selecting and specifying a wireless device in order from the list of wireless devices that have returned the identification code is provided in the management address setting device, and the identification code of the wireless device selected and specified by this function is assigned to a wireless device within a communicable area Alternatively, it may be transmitted. In this case, if the wireless device selected and specified reports its own location and the wireless device that has notified its location is not the desired wireless device, the selection and selection of the next wireless device is automatically performed at the discretion of the operator.
