DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of an evacuation guidance device in the event of a fire according to the present invention. In the drawing, reference numeral 1 is installed on a ceiling or a wall in a building, and the occurrence of a fire and the situation thereof. The fire detection sensor 2 for detecting the fire is installed in the ceiling or in the wall, and when the power is not supplied from the commercial power source to the fire detection sensor 1 due to a fire occurrence or a power failure due to the fire, the power is automatically supplied instead. The battery 3 to be supplied to the antenna 3 is installed on the ceiling or the like, the antenna for transmitting the information signal regarding the fire from the fire detection sensor 1, and the reference numeral 4 is driven by the information signal transmitted from the antenna 3 and this information It is an evacuation guidance vehicle that guides evacuees to a safe place while selecting a safer evacuation route based on signals.

The evacuation guidance vehicle 4 has a receiver 6 for receiving the information signal from the antenna 3 through the antenna 5, an arithmetic unit 7 for calculating the information signal received by the receiver 6, and a driving device for running. A battery 8 for supplying electric power is provided.

The evacuation guidance vehicle 4 is also provided with a rope 9 for directly pulling and guiding the evacuee, a display 10 for displaying the fire situation to the evacuee, an oxygen mask 11 used by the evacuee during evacuation, and the like. ing.

Further, the evacuation guidance vehicle 4 is constructed so that it can freely travel on a passage such as a staircase other than a flat place by means of a caterpillar.

The fire detection sensor 1 is installed in a grid pattern on the ceiling or wall of a building at predetermined intervals in front, back, left and right (see FIG. 2). In addition to information signals related to the occurrence and status of a fire, a recognition signal unique to each fire detection sensor is transmitted from 1, and the evacuation guidance vehicle 4 can grasp the current position by the recognition signal when approaching the fire detection sensor. It is like this.

Further, a map of the relevant floor is input to the arithmetic unit 7 in advance, and when a fire occurs, the evacuees are safed while selecting the route with the least risk based on the information signal from the fire detection sensor 1. It has a structure that can be guided to.

The evacuation guidance vehicle 4 is individually equipped with a processing system for processing the information signal from the fire detection sensor 1 and an operation system for operating the evacuation guidance vehicle 4 based on the information signal. Even if the function of one system is stopped, it is considered that the other system does not function and the whole system does not go down.

Explaining how to select an evacuation route, a numerical value indicating the risk of ignition (hereinafter referred to as "danger value") is set for each fire detection sensor, and this danger value is set higher as the possibility of ignition increases. . For example, when a fire occurs in a certain place, the dangerous value of the installation point of the fire detection sensor facing the fire occurrence point without any shielding member is the value of the fire installation sensor facing the shielding member such as a fire door. Set higher than the dangerous value at the installation point. In addition, a coefficient (hereinafter referred to as "fire spread value") indicating the ease of fire spread is set for each fire detection sensor, and the fire spread value is set to be high according to the ease of fire spread, similar to the dangerous value.

When a fire occurs near the installation point of a certain fire detection sensor, the danger value and the spread value of the surrounding fire detection sensor installation points increase in accordance with the set coefficient. Then, the evacuation guidance vehicle guides the evacuees by selecting the route in which the sum of the dangerous value and the fire spread value is the minimum as the safest evacuation route.

For example, in FIG. 2, reference numeral 12 is a fireproof partition wall for partitioning the interior of the building into a plurality of parts, 13a, 13b, 1
3c and 13d are living rooms formed by further partitioning the interior of the fireproof partition defined by the fireproof partition wall 12 with a partition wall 14, and reference numeral 15 is each living room 13a, 1
It is a passage for going back and forth between 3b, 13c, and 13d.

In such a plane, for example, the living room 1
When a fire occurs in 3a, the danger value of the fire detection sensor 1 installed on the ceiling or wall of the living room 13a is high,
Moreover, the value increases as the location of the fire approaches.
Also, the fire spread value increases as it nears the point of fire.

On the other hand, the fire detection sensor 1 installed on the ceiling or the wall of the passage 15 has a low danger value and a fire spread value because the partition wall 14 is interposed, and the value becomes smaller as the distance from the fire starting point increases. Become. Further, the fire detection sensor 1 installed outside the fireproof partition wall 12 has a further smaller danger value and spread value.

Therefore, in this case, the evacuation guidance vehicle 4 is installed in the living room 1.
Residents left behind in 3a are guided directly from this room 13a to the passage 15 and further to the outside of the fireproof partition wall 12 for evacuation. A flowchart of the evacuation method in this case is shown in FIG.

When a fire occurs in the living room 13a (step S1), all the fire detection sensors 1 installed on the wall or ceiling in the building are activated (step S2), and the dangerous value and the spread value of fire at the respective places are detected. Show. Then, the information signal regarding the fire in the living room 13a is transmitted to the evacuation guidance vehicle 4 via the antenna 3 (step S3).

Next, in the evacuation guidance vehicle 4, in the arithmetic unit 7, based on the information signal from each fire detection sensor 1,
The safest evacuation route, that is, the route where the sum of the dangerous value and the spread value is the smallest is calculated (step S4).

Next, when the evacuation route is determined, the evacuation guidance vehicle 4 directly leads the occupants left behind in the living room 13a to the passage 15 and further to the outside of the fireproof partition wall 12 based on this. And evacuation guidance (step S5). In this way, the evacuation guidance vehicle 4 guides the evacuees to the outside of the fireproof partition wall 12 while selecting the safest evacuation route.

[0022]

The present invention is constructed as described above, and the evacuation guidance vehicle is based on the information signal regarding the fire from the fire detection sensor installed on the ceiling, wall, etc. in the building.
Evacuation guides evacuees directly to safe places while selecting the safest evacuation route, so evacuees are guided very safely even if there is no visibility at all due to smoke or darkness, or if the evacuation route is completely unknown. There is an effect that can be done.
