Description

[Detailed description of the invention] This invention relates to an evacuation guidance system.

Evacuation exit guide lights are installed in buildings and underground malls to direct people to the evacuation exit in the event of a fire occurring inside the building, but conventional indicator lights indicate the location of the evacuation exit. This is inconvenient because, for example, dangerous evacuation exits in the vicinity of a fire are also displayed. Therefore, an object of the present invention is to be able to distinguish between danger and safe evacuation exits and provide a warning using a simple configuration.
It is an object of the present invention to provide an evacuation guidance system that gives priority to notification that evacuation is impossible when a fire breaks out in the above locations.

FIG. 1 shows an evacuation suitability warning means using an evacuation exit guidance indicator light according to the present invention as an embodiment, FIG. 2 shows a circuit of the embodiment, and FIG. 3 shows an example of its installation.

In those figures, 1 is a guide light section that marks the normal evacuation exit position, 2 is a compliance display section, and an O mark display section 3 and an X mark display section 4 are provided above the guide light section 1. The evacuation suitability warning means 5 is structurally constituted by these parts. 6
7 is the first notification means for notifying that evacuation is not possible, using the lamp corresponding to the × mark display section 4 as an example, and 7 indicates that evacuation is possible, using the lamp corresponding to the O mark display section 3 as an example. 8 is a fire detection relay connected in parallel with the lamp 6; 9 and 10 are contact portions of the relay 8; a normally open contact portion and a contact portion of the contact portion 9; 10 normally closed contact portions form a series circuit and are connected in series with the lamp 7, and these parts constitute the evacuation suitability warning means 5 in a circuit form.

A and B are power bus lines, and C is a control line. Between the power bus lines A and B, the relay 8 and lamp 6 of the evacuation suitability warning means 5 described above are connected via the fire detector 5, and the lamp 7 and A series circuit of contact portions 9 and 10 is connected. Further, the normally open contact of the contact portion 9 described above is connected between the power bus A and the control line C. On the other hand, inside buildings and underground malls are divided into multiple warning areas into 9 blocks, and evacuation suitability warning means 5 are installed in each of blocks K1 to K4, which include evacuation exits H1 to H1. It is connected to the fire detectors S1 to S4 arranged therein. Block K5 without evacuation exit H
~K9, only the fire detectors S5~S9 are arranged, and are connected between the power supply bus A and the control line C. In such equipment, when a fire occurs in block K1, fire detector S1 is activated. When the fire detector S operates, the first notification means 6 of the evacuation suitability warning means 5 lights up and an X mark is displayed on the X mark display section 4, indicating that it is dangerous to evacuate through the evacuation exit H1. is displayed. At this time, the relay 8 is also energized, so the normally open side of the contact part 9 is closed, the control line C is connected to the power bus A through the contact part 9, and a voltage is generated between the power bus B and the control line C. , the contact portion 1 in the evacuation suitability warning means 5 of the other blocks K2 to K4.
Electric power is supplied to the lamp 7 through 0, the second notification means 7 lights up, the O mark display section 3 is activated, and the evacuation exit H2~
It is marked that it is safe for H4 to escape. In this way, if a fire breaks out in any of the blocks K1 to K1, it is displayed that only the evacuation exit of the block where the fire occurred is dangerous, and that the others are safe. Also, Fig. 2 shows blocks K1 to K.
Even if a fire occurs in two or more of 4, even if the O mark display part 3 is activated due to the fire that occurred first in the block where the fire occurred later, it will be switched to the × mark display part 4. It has become a priority circuit. Next, when a fire breaks out in block K9, fire detectors S5 to S9 are activated, control line C and power bus A are connected, and voltage is generated between power bus B and control line C. Then, in each evacuation suitability warning means 5, the second notification means 7 is energized via the contact portion 10, the O mark display portion 3 is activated, and it is displayed that the evacuation exits H1 to H4 are safe. In this way, whether or not each evacuation exit H is safe for escape is appropriately displayed, and evacuation of people can be carried out effectively.
In addition, in the embodiment, one marker light is provided for each block, but a plurality of marker lights may be provided, or a plurality of display portions including lamps may be prepared and distributed in one marker light. .

In addition, the suitability display section is not limited to the Ox display, but also the green light and
It may also be a red light display, etc. FIG. 4 shows another embodiment according to the present invention, in which the visual suitability display section 2 in FIG. 2 is shown.
Instead, tape recorders 11 and 12 and a speaker 13 which are embodiments of the first notification means 6 and the second notification means 7 are used.
, 14 is provided, and
The contact part 9 is removed and a diode 16 for control transmission is connected between the control line C and the power supply bus A via the fire detector S, and the tape recorder 11 is activated by the fire detector S and zeros. The tape recorder 12 broadcasts that this evacuation exit cannot be used, and the tape recorder 12 closes the other fire detection contact S.
It is activated by connecting the power supply bus A and the control line C directly or through the diode 16 of the suitability display section 15 of another component, and by broadcasting the message "Please evacuate from this evacuation exit", the evacuation exit is activated. Notify the suitability of the

As described above, according to these embodiments, the inside of a building is divided into a plurality of blocks, a fire detector is placed in each block, and the evacuation exit of the block where the fire detector is activated due to a fire outbreak cannot be used for evacuation. We are trying to notify people that evacuation exits in other blocks are possible, so we can designate evacuation exits that are in danger and safe evacuation exits, and guide and evacuate people safely. In addition, as a means of notification, the configuration in which a suitability indicator is added to the guidance light section for the evacuation exit position marker, which has been conventionally used as shown in Figure 1, has an extremely simple structure and can be used in normal times. This has the effect of displaying only the location of the evacuation exit, and displaying only the suitability of evacuation in the event of a fire. With this circuit configuration, a single control line controls all compliance display parts,
The effect is that the desired function can be satisfactorily achieved with simple wiring.

As described above, according to the evacuation guidance system of the present invention, a fire detector is installed in each block divided into predetermined sections, and a fire detector is installed in a predetermined block among the blocks. , a first notification means for notifying that evacuation is impossible and a fire detection relay connected between the power bus bars via the fire detector of the block, and between one of the power bus bars and the control line. and a second notification means for notifying that evacuation is possible, which is connected via the normally closed contact of the fire detection relay;
Due to the operation of the fire detector of the block having the evacuation suitability warning means, the first notification means is activated and at the same time the connection between the second notification means and the control line is disconnected;
and the other of the power busbars is connected to a control line, so that the second notification means of the evacuation suitability warning means of the other block is connected to the power supply busbar through the control line and supplied with power. With this feature, it is possible to distinguish between dangerous and safe evacuation exits with a simple configuration, and to notify the user that it is impossible to evacuate to that location even if a fire occurs in two or more locations. It has the effect of being safe.
