, 1-n-1-2 and the base station 5-n-2 for the environment control unit 1
-N-2-1 and 1-n-2-2 are controlled.

Next, referring to FIG. 4 together with FIGS. 1 and 2, the environmental control associated with the operation and movement of the PS6-p will be described.

First, PS6-with the switch turned on
If p enters the second floor of building 10, PBX30 will be PS6
Since -p is detected based on the information from the base station 5-2, the gateway device 21 receives from the CPU 31 the occurrence information "PS6-p occurs in the base station 5-2" (step S1). Upon receiving this information, the gateway device 21 enters PS6- in the stay PS area corresponding to the base station 5-2 in the stay PS table.
Register p (step S2).

Next, the gateway device 21 checks the registration status of the staying PS area of the base station 5-2, and if this registration is the first time in the staying PS area of the base station 5-2 (YES in step S3), the grouping table is displayed. To check the environment control unit 1-2 within the environment control range of the base station 5-2, and notify the building management device 20 that the control of the environment control unit 1-2 is required. Upon receiving this notification, the building management device 20 checks the operating state of the environment control unit 1-2, and if the environment control unit 1-2 is stopped, activates the environment control unit 1-2 (step S
4).

If the step S3 is "NO" or the environment control section 1-2 is operating in the step S4, the gateway device 2
1 waits for operation information for environmental control from PS6-p (step S5).

The PS6-p holder on the second floor can activate the PBX 30 by a predetermined special transmission code and perform the same environmental control operation with the gateway device 21 according to a predetermined protocol. , Can control the environment control unit 1-2 on the second floor.

Next, referring also to FIG. 5, PS6-p is 2
The case of moving from the first floor to the nth floor will be described.

First, since PS6-p moves from the second floor, the CPU 31 in the PBX 30 receives the disappearance information of PS6-p from the base station 5-2 on the second floor. Therefore, the gateway device 21 causes the CPU 31 to display "PS6-p is the base station 5-
The disappearance information "Disappear from 2" is received (step S11).
Upon receiving the disappearance information, the gateway device 21 deletes PS6-p from the corresponding area of the base station 5-2 in the stay PS table (step S12).

As a result, the PS in the corresponding area of the base station 5-2 is
When the registration of No. 6 is lost (YES in step S13), the gateway device 21 searches the grouping table to check the environment control unit 1-2 within the environment control range of the base station 5-2, and checks the environment control unit 1- The building management device 20 is notified that the control of 2 is required. The building management device 20 receiving this notification checks the operating state of the environment control unit 1-2, and if the environment control unit 1-2 is in operation, stops the operation of the environment control unit 1-2 (step S14). , End the procedure.

On the other hand, if the step S13 is "NO", the base station 5-
If the PS6 is still registered in the corresponding area of 2, the operation information of the environmental control is awaited (step S15).

Next, the PBX 30 has the base station 5- on the nth floor.
The PS 6-p is detected from the information from n, and the CPU 31 notifies the gateway device 21 that “PS 6-p is the base station 5-
Occurrence information of "occurs in n" is transferred. Upon receiving this information, the gateway device 21 repeats the above-described operation procedure described with reference to FIG. 3, that is, registering PS6-p in the staying PS area of the base station 5-n in the staying PS table.

That is, in the illustrated example, the gateway apparatus 21 checks the registration status of the staying PS area of the base station 5-n, and PS6-q has already been registered in the staying PS area of the base station 5-n. Therefore, it waits for the operation information of the environmental control received from the registered PS6.

In the above description, in the conference room, the reception room, etc., as an embodiment which is effective for the environment control of each room, the environment controller is powered on / off depending on the presence / absence of PS within the communication range of the base station. Although the control for immediately performing the operation is illustrated and described, with this configuration, a temporary office is not used in a normal office.
In the S state, the power supply to the environment control unit is cut off, and for example, the temperature was lowered in winter, the power supply was restarted because the PS entered the room, and due to rapid heating, a large amount of power was consumed compared to the power for maintaining an appropriate temperature. The opportunity arises.

In order to solve this problem, there may be a function of turning off the power after an appropriate predetermined time has passed.
Needless to say, it is still convenient if this elapsed time is variable. Specifically, the delay time may be variably set for each PS, or the power supply cutoff time may be delayed by concentrating or dispersing on the environment control means side.

As described above, further convenience can be obtained by combining the functions according to the well-known technique in the present invention.

Further, in the above description, it was explained that the environment control unit at the location where the PS is present is brought into the operating state and then the environment is controlled by operating the PS again, but the environment information is preset for each PS. Incidentally, when a new stay is registered in the communication range of the base station, the gateway device managing the stay PS table may have a function of requesting and fetching the environmental information set in the corresponding PS.

In the above description, the connection between the PBX, the gateway device, and the building management device is RS232C.
Although the interface and the LAN interface are used, another interface may be used. Further, although the stay PS table or the grouping table is provided in the gateway device, it may be provided in another device such as a building management device.

Although the present invention has been illustrated and described in this way, the distribution by separating and merging functions is free as long as the above functions are satisfied, and the above description does not limit the present invention.

[0039]

As described above, according to the present invention, a floor environment control system using a private branch exchange that uses a mobile telephone as a telephone for controlling the floor environment and uses the mobile telephone as a remote controller can be obtained.

With this configuration, since the mobile phone of the remote controller can send and receive control information to and from the antenna of the base station by radio waves, the mobile phone at hand can control the floor environment even when the user leaves the seat and the cabinet environment of the cabinet can be controlled. It is possible to avoid the uncontrollability due to the shield below the line of sight.

Further, the private branch exchange identifies a mobile phone with which each base station can communicate and sends a notification, and the environment control means of the environment control unit corresponding to the base station with no stay information of the mobile phone. Since the power is controlled to be turned off (off), it is possible to automatically turn off the power of an unattended floor or room without the operation of turning off the power.

Further, when the mobile phone has a predetermined environmental condition set in advance and has a function of receiving a predetermined control information request in a switch-on state and transmitting the set environmental condition according to a predetermined protocol, By setting the conditions according to the season in advance, it is possible to make daily operation of each mobile phone almost non-operational.

If the environment control unit has a function of controlling the power supply to be cut off after a predetermined time has elapsed when the power supply or the switch is turned off (off), an appropriate time is required. The settings help save operating power for the environmental controls.
