Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a private branch exchange system with a position display function according to the present invention. FIG.
Indicates a mobile station in a mobile private branch exchange network (PHS or the like) superimposed on a floor plan of the premises.

Reference numeral 10 denotes a mobile station to be guided owned by a guided person (a guest at a hotel, a patient at a hospital, etc.), and 11 denotes a mobile station owned by a guide (an employee at a hotel, a nurse at a hospital, etc.). And 20 is a base station, 2
1 is a private branch exchange, 30 is a position display device, 40 is a disaster occurrence location, and 51 is a disaster monitoring system in the premises. 2
2 is a private branch exchange operator, 31 is a database, 3
Reference numeral 2 denotes a position display management unit.

The database 31 stores the disaster monitoring system 5
It has the position information of the sensor unit 50, the base station 20, the evacuation tool 60, the evacuation exit 61, and the individual information (personal name, assigned duties, etc.) of the mobile station 10 and the mobile station 11. The disaster occurrence location 40, the base station 20, the mobile station 10, the mobile station 11, the evacuation tool 60, and the evacuation exit 61 are displayed by the position display device 30 in respective colors and shapes. Also, individual information of the mobile station 10 and the mobile station 11 can be displayed.

The private branch exchange system shown in FIG.
0 and the position of the mobile station 11 are specifically specified, the individual identification of the mobile station 10 and the mobile station 11 is enabled by the management number of the mobile station, and a broadcast notification function to the mobile station 10 or the mobile station 11 is provided.

If the location 40 where a disaster such as a fire has occurred is clear, it is displayed in accordance with the position display device 30, and it is possible to instruct the mobile station 10 and the mobile station 11 to move to a nearby evacuation exit 61. To

Next, the operation of this embodiment will be described in detail with reference to FIGS. FIG. 2 is a flowchart for explaining the operation of this embodiment.

When a disaster such as a fire occurs at the disaster occurrence location 40, the position of the disaster occurrence location specified by the disaster monitoring system 51 is notified to the position display management unit 32 (step 1).

The position display management unit 32 displays the notified position on the position display device 30 using the database 31 (step 2).

At the same time as the occurrence of the disaster, the private branch exchange 21 requests the mobile station 10 and the mobile station 11 for location registration (step 3). If a disaster location such as an earthquake cannot be identified, the process is executed from step 3.

In response to the location registration request returned from mobile station 10 and mobile station 11, location display management section 32
Specifies each position with reference to the database 31,
The information is displayed on the position display device 30 (step 4).

The response may be made automatically or may be made by the operation of the mobile station owner. The specification of the position is accurately performed by using data collected by a plurality of base stations and calculating by a method (for example, trigonometry or the like) that specifies the position in more detail than data received by a single base station.

The operator 22 broadcasts disaster information to the mobile stations 10 and 11 by broadcast notification. In addition, the operator 22 may only operate the mobile station 10 if necessary.
Alternatively, a broadcast notification is sent only to the mobile station 11 (step 5).
Further, the operator 22 communicates with a specific mobile station 10 or mobile station 11, and gives an evacuation instruction and a guidance instruction by communication (step 6).

It is to be noted that the premises refers to a certain specific area, and may be outdoors. The position of the mobile station can be determined more accurately by calculation by trigonometry or the like. In the case of a wide area such as a wildfire, it is possible to use a telephone exchange system having a wider radio wave range than the PHS. In a place where a large number of people gather, such as a stadium, the attendant may have the mobile station 11 and the operator may give only instructions to the attendant.

Since the system uses a private branch exchange, the position display function of the mobile station can be used in normal times, and a function as a private branch exchange network can be used. Cooperation with disaster monitoring systems is not always necessary.

Further, it is possible to give priority to communication between the operator and the mobile station and between the mobile station and the mobile station by a broadcast notification or a communication direction.

[0026]

As described above, according to the present invention, evacuation and evacuation guidance at the time of disaster can be individually performed.
In addition, since the position of the guide requiring rescue and the position of the rescuer required can be specified, quick rescue is possible. By using the mobile station telephone network, it is possible to confirm the situation by communication. Because it is on the premises, geographic information can be accurately reflected and more accurate evacuation instructions can be made.
