Thereby, the worker in the common groove 18 can be accurately grasped at the monitoring center 30. Of course, the display does not have to be a graphic display, and for example, only the area where the worker is present may be displayed in the form of a list 83 in which the worker name and the telephone number are associated with each other. It can be said that the graphic display is excellent in that it can be visually recognized.

Next, claim 3, claim 13 and claim 1
An embodiment of the invention described in 4 will be described. In each slave station 23 in the common groove 18, the output states of the fire detector 24, the gas leak detector 25, and the oxygen deficiency sensor 26 are constantly scanned at regular intervals to collect information on the occurrence of a disaster, and the disaster occurrence. The presence / absence information to which the identification number (area number) of the own station is added is transmitted to the parent station 31 at predetermined intervals.

At this time, the fire detector 24, the gas leak detector 25, and the oxygen deficiency sensor 26 are set at a plurality of locations, so that in each slave station 23, the physical arrangement positions of these disaster detection ends are set. And the content (type) of the disaster detection end will be collected in association with each other. In the master station 31, the disaster occurrence information sent from each slave station is edited for each area and a disaster management table is generated to prepare for a disaster occurrence. The presence or absence of a worker can be determined by searching the above-mentioned grooved person management table by the area number. FIG. 18 is an example of the disaster management table. As shown in FIG. 18, the disaster management table shows the disaster occurrence place and the disaster contents associated with each other in each area, but is simplified in FIG. 18.

That is, as described above, since each disaster detection end is set in a plurality of places in the same area, the disaster management table actually sets the location of each disaster detection end (disaster occurrence) for each area. The location and the output state (contents of the disaster) of the disaster detection end are generated so that they can be grasped in a one-to-one correspondence. When the disaster actually occurs, the master station 31 sounds the buzzer 34 and updates and sets the location and contents in the relevant area of the disaster management table, and searches the in- groove person management table to work in that area. It is confirmed that there is a person, and the measures of each embodiment described below are taken.

Next, an embodiment of the invention described in claims 4 and 14 will be described. In this embodiment, the guide light 27 guides the worker to evacuate. As mentioned above, the guide light 27
Are also arranged in the same area, but this is because each area is large and the evacuation route can be selected according to the disaster occurrence place. In the master station 31, for example, FIG.
A guide light control table as shown in FIG. 9 is provided to guide the people in the ditch to evacuate.

In FIG. 19, in the illustrated example, if three disaster detection ends (disaster occurrence locations) A, B, and C are provided in area 1, for example, if the disaster occurrence location is A, then a1 , A2, a3 are controlled by blinking lights and the disaster occurrence location is B, b
If the guide lights at the positions defined as 1, b2, and b3 are controlled by blinking lights and the disaster occurrence place is C, c1, c
The guide lights at the positions defined as 2 and c3 are controlled by blinking lights, and the guide lights for which the blinking lights are controlled are set in advance in groups according to the disaster occurrence place.

Since the person in the groove can be grasped by the person in the groove management table as described above, when the disaster actually occurs, the guide light control table is searched by the area number where the worker is and the disaster occurrence place. Then, the control target guide light is specified, the control target guide light is transmitted to the slave station 23 in the area, and the target guide light is controlled to blink. If you need
The guide lights are controlled to blink over a plurality of areas.

If the disaster management table is searched and there is another area where the disaster has occurred, the guide lights are controlled as described above for the disaster occurrence location in that area. Next, an embodiment of the invention described in claim 5 will be described. In this example,
The mobile phone 29 notifies the worker of the occurrence of the disaster and guides the evacuation. Therefore, the master station 31 has an automatic notification table as shown in FIG. 20, for example.

In FIG. 20, this automatic notification table is prioritized to the areas to be notified according to the number of the disaster occurrence area, the mounting position and type of the disaster detection end that has detected the disaster occurrence (location / content of the disaster occurred). And the type (voice number) of the voice message to be reported. This voice message is generated by voice synthesis.

For example, if A indicates a fire, B indicates a gas leak, C indicates oxygen deficiency, and each disaster detection end is 3
If it is set in one place, A1 in area 1
When the fire detector 24 of detects a fire, the priority is set to 1, 2, ...
The number 1 indicating the message of fire occurrence is set as the voice number. The same applies hereinafter.

When the disaster actually occurs, the master station 31
