Each equipment controller 2 includes a GPS receiver 21, a PHS transceiver 22, a communication controller 23 that communicates with the host controller 3, a communication controller 24 that communicates with the equipment 1 under management, and the entire controller. A control unit 25 for controlling and a storage unit 26 for storing the program of the control unit 25 and the communication address assigned to the own device are provided.

The user terminal device 6 includes a PHS transceiver 61.
A display unit 62 for presenting information to the user, an operation unit 63 for giving an instruction to the terminal device 6 by the user,
A control unit 64 that controls the entire apparatus and a storage unit 65 that stores the program of the control unit 64 are provided.

The communication address setting method in the building management system will be described below. FIG. 4 is a flow chart showing the communication address setting method. First, the GPS receiver 21 of each equipment controller 2 is a GP (not shown).
The position of the own device (equipment controller 2) is detected by receiving the radio wave from the S satellite, and the PHS transceiver 22 communicates with the PHS base station (not shown) through the PHS network 7 to determine the position of the own device. It is detected (step 101 in FIG. 4). P
When using the HS transceiver 22, the PHS transceiver 2
Paying attention to that 2 always communicates with the nearest PHS base station and holds nearby base station information, the position of its own device is estimated from this base station information.

GPS receiver 21 or PHS transceiver 22
Passes the detected position information to the control unit 25. Control unit 25
If the communication address of the own device is not set in the storage unit 26, the communication address setting request including the position information is sent to P
The communication address setting request is sent to the HS transmitter / receiver 22 and is transmitted from the PHS transmitter / receiver 22 to the user terminal device 6 (step 102). In this way, the equipment controller 2
The position information of is notified to the user terminal device 6 via the PHS network 7.

Next, the PHS transceiver 61 of the user terminal device 6 receives the communication address setting request transmitted from the PHS transceiver 22 of the equipment controller 2 and receives the control unit 64.
Then, the control unit 64 extracts the position information of the equipment controller 2 from this communication address setting request and displays it on the display unit 62.
Is displayed (step 103). Then, the control unit 64
Identifies the requesting facility controller 2 based on the received position information (step 104).

Next, the control unit 64 generates a communication address unique to the identified equipment controller 2 (step 1
05). As will be described later, since the set communication address is registered and managed in the database of the storage unit 65, an unregistered communication address may be generated in this database. The communication address is the equipment controller 2
It is not necessary to separately set each system.

Subsequently, the control unit 64 registers the generated communication address in the database, passes the communication address to the PHS transceiver 61 to notify the equipment controller 2 of the request source, and requests from the PHS transceiver 61. It is transmitted to the original equipment controller 2 (step 106).
FIG. 5 is a diagram showing the structure of the database stored in the storage unit 65. In FIG. 5, "Adr ○○○" indicates a communication address. In the database stored in the storage unit 65, the position information of each equipment controller 2 and the communication address are registered in association with each other.

Next, the PHS transmitter / receiver 22 of the equipment controller 2 receives the communication address transmitted from the PHS transmitter / receiver 61 of the user terminal device 6 to the controller itself, and receives the communication address.
5, and the control unit 25 sends this communication address to the storage unit 2
6 (step 107). In this way, the communication address unique to the equipment controller 2 is set. The control unit 25 of the equipment controller 2 uses this communication address to exchange data with the host controller 3 and the central monitoring device 4.

Next, a confirmation test method for confirming whether the communication address is correctly set in the equipment controller 2 will be described. FIG. 6 is a flowchart showing the confirmation test method. First, the user operates the operation unit 63 of the user terminal device 6 to select the communication test mode,
Specify the communication address to be tested (step 20)
1). When the communication test mode is selected, the control unit 64 of the user terminal device 6 issues a predetermined processing command to the communication device having the specified communication address (step 2).
02). The processing command transmitted from the PHS transceiver 61 of the user terminal device 6 is received by the PHS-communication line protocol conversion means (not shown) connected to the communication line 5, and converted into a format conforming to the protocol of the communication line 5. It is sent to the communication line 5 (step 203). When the communication device of the transmission destination receives the processing command addressed to itself from the communication line 5, the communication device returns a response according to the processing command.
This response is received by the PHS-communication line protocol conversion means, converted into a format conforming to the protocol of the PHS network 7, and sent to the PHS network 7.

Subsequently, the control unit 64 confirms through the PHS transceiver 61 whether or not a normal value has been returned from the transmission destination communication device in response to the transmitted processing command, and the confirmation result is displayed on the display unit 62. (Step 204). At this time, when a normal value is received within a predetermined time, it is displayed as normal, and when an abnormal value is received or there is no response from the communication device within the predetermined time, it is displayed as abnormal. If the confirmation result is abnormal, the control unit 64 proceeds to step 1
The processing after step 05 is performed again to reset the communication address (step 205).

As described above, according to the present embodiment, the position information of the communication device (facility controller 2) is used to
By setting the communication address of each communication device, the installation location and communication address of the communication device can be managed collectively. This can reduce the possibility of duplicated setting of communication addresses. In addition, it will be possible to build a tool that performs all remote site construction and adjustments.

As a method for identifying the requesting equipment controller 2 in step 104, the received position information is collated with the position information registered in advance in the database, and the requesting equipment controller 2 is identified. There is a way to identify. In this case, the generated communication address is registered in the database in association with the registered position information.

If the position information is not registered in the database, based on the number (telephone number) peculiar to the PHS transmitter / receiver 22 of the requesting equipment controller 2 on the wireless line (PHS network 7), The requesting facility controller 2 is identified. In this case, the generated communication address and the received position information are associated with each other and registered in the database.
