The fire receiver 2 receives the fire detection signal from the sensor 1,
The fire occurrence is transmitted to the central control terminal 3. Upon receiving the output from the fire receiver 2, the centralized management terminal 3 determines the fire / flame occurrence location according to the signal reception, and determines the optimal evacuation route for each room based on the determination, A fire / flame occurrence location and an optimal evacuation route are transmitted to each karaoke terminal 4. When the karaoke terminal 4 receives the output from the centralized management terminal 3, the karaoke terminal 4 displays the fire / flame occurrence location and the evacuation route on the monitor 12. FIG. 4 shows a display screen of the monitor 12 installed in room 303 as an example of the evacuation route display screen of the monitor 12. There is a fire on the monitor 12.
The optimal evacuation route corresponding to each room is displayed along with the flame occurrence location.

FIG. 5 shows the relationship between the evacuation route and the sensor. This example is for room 303. A sensor 301 is arranged in the corridor in front of the elevator 16, and the rooms 301 to 305
Sensors 302 to 30 are provided in each room of the room No.
6 are arranged. Each room is an evacuation route with stairs 17
It has an evacuation route 1 for evacuating to and an evacuation route 2 for evacuating to the emergency stairs 18, and one of the evacuation routes can be selected depending on the place where the fire or flame occurs.

FIG. 6 shows an example of a sensor group for deciding which evacuation route to select, which is 303 in this example.
This is the case for room number. The sensors 301, 302 and 303 are assigned as the evacuation route 1 adjacent group, the sensors 305 and 306 are assigned as the evacuation route 2 adjacent group, and the sensors 304 are assigned as other groups.
The grouping of the adjacent sensors for each evacuation route is performed for all rooms, and the data regarding these evacuation routes is stored in the centralized management terminal 3. FIG. 7 shows an example of the data. When a fire occurs, the centralized management terminal 3 selects an optimal evacuation route for each room based on the data shown in FIG. 7 and installs it in each room. It is displayed on the monitor 12.

Details of the evacuation route selection operation in the centralized management terminal 3 will be described with reference to the flowchart of FIG. First, it is checked whether or not the evacuation route 1 includes a sensor of a fire / flame generation point (S1), and if it does (YE in S1).

No), and in S3, it is checked whether or not the evacuation route 2 includes a sensor at a fire / flame generating point.

For example, in FIG. 5, assuming that a fire has occurred in room 302 and the sensor 303 has operated,
As shown in FIG. 7, since the sensor 303 belongs to the evacuation route 2, the selection operation corresponding to the room 1 is NO in S1 and YES in S3. In this case, the process proceeds to S6 and the evacuation route 1 is selected. It In addition, as a selection operation corresponding to room 302, which is a place where a fire or flame is generated, the sensor 30
Since 3 belongs to the others, NO in S1 and NO in S3. In this case, the process proceeds to S7 and the evacuation route 1 and the evacuation route 2
Is selected. As for the selection operation corresponding to the room No. 303, the sensor 303 belongs to the evacuation route 1, so S1
And YES in S2 and NO in S2, in this case, proceed to S5,
Evacuation route 2 is selected. If the sensor of the fire / flame generation location belongs to the evacuation routes 1 and 2, YE in S1.
If S and S2 are YES, in this case, the process proceeds to S4, no evacuation route is selected, and all the fires and flames and all evacuation routes are displayed on the monitor 12 together with the fact that the evacuation is being performed with sufficient caution.

The present invention is not limited to the above embodiment, but various modifications can be made without departing from the spirit of the invention.
