Description

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

When a fire breaks out in an underground mall or inside a building, many people die as a direct result of the smoke and toxic gas.

In most cases, this is because people are unable to find their way and are unable to escape, leading to people panicking and being pushed or trampled to death.

What's more, most people will be surrounded by smoke or toxic gas and die, creating an extremely dangerous situation.

Guidance lights are normally installed in underground malls and passageways inside buildings, but these simply indicate nearby emergency exits and do not indicate the safe direction for evacuation in the event of a fire.

Therefore, the applicant of this patent proposed an evacuation guidance method for guiding evacuation to the nearest emergency exit without passing through the point of fire occurrence, and filed a patent application (Japanese Patent Application No. 1983-66277).

However, not all passageways are safe to pass through.

For example, if a passageway is under construction or contains explosive or flammable hazardous materials, it is extremely dangerous to evacuate through that passageway in an emergency.

Therefore, an object of the present invention is to provide an evacuation guidance system that can guide evacuation to the nearest emergency exit while avoiding dangerous passages.

In the evacuation guidance system of the present invention, a control unit for controlling signal transmission and evacuation direction indicators is provided corresponding to each passage, and the signal transmission lines of the control unit are connected in the same pattern as the passage.

Passage closure designating means for blocking the passage depending on the dangerous state of the passage are connected to the control unit.

An emergency exit signal source is provided to supply an emergency exit signal to the signal transmission line corresponding to the emergency exit when an emergency situation occurs.

Evacuation direction indicators will be installed in each aisle.

The control unit transmits an emergency exit signal, uses an evacuation direction indicator to indicate the direction opposite to the direction in which the signal is transmitted, and maintains that state even if an emergency exit signal is generated from the opposite direction.

Additionally, an emergency detector such as a fire detector may be provided in the passageway.

In this case, when an emergency situation occurs, the sensor at the occurrence point emits a sensing signal, and the signal transmission function and indicator control of the control unit corresponding to the passage at the occurrence point and the control unit driven by the missed signal generation means stop functioning.

On the other hand, when an emergency situation occurs, an emergency exit signal is sent from the emergency exit signal source to the control unit corresponding to the passage closest to the emergency exit.

Next, the signal is sent from that control unit to a control unit provided corresponding to another passage adjacent to that passage.

In this case, the signal is sent bypassing the path at the generation point and the control unit driven by the missed signal generating means.

In this way, dangerous passages can be avoided from the point where an emergency situation occurs by sequentially shifting the emergency exit signal to the control unit installed corresponding to each passage and setting the direction opposite to the direction in which the signal is transmitted as the evacuation direction. Direct people to the nearest emergency exit.

FIG. 1 is a block diagram of an embodiment of the evacuation guidance system of the present invention.

The figure shows passages inside underground malls, buildings, etc. The passages between intersections are designated as fire warning zones 1 to 10, and fire detectors 81 to SIO are located within the warning zones 1 to 10.
and evacuation direction indicators H1 to H1o will be installed.

Each of the evacuation direction indicators H1 to H1o is a pair of indicator lights HIA and Hta.

- Consists of H1oA and H1oa.

Figure 2 is a control system diagram of Figure 1, with control units U1 to U.
1o are arranged corresponding to each passage in Fig. 1, and each control unit is connected to each other by an emergency exit signal transmission line, and each control unit U1 to UIO is a fire detector installed in the passage corresponding to its placement location. S1 to StO and passage interruption designation switch R1
~RIO is connected.

The emergency exit signal source also includes a terminal E1. Connected to E2.

And this terminal E1. E2 is connected to the emergency exit signal transmission line.

3 is a plan view of the monitor display panel of the control system circuit of FIG. 2. FIG.

In the figure, arrows M1 to M1o indicate indicator lights H1A and H1a to H1 of the evacuation direction indicators H1 to H10 shown in FIG.
oA and H1oa monitor indicator lights, F1 to F10 are fire occurrence point indicator lights, and R1 to R1o are passage closure designation switches.

FIG. 4 shows the basic configuration of the control units U1 to U1° shown in FIG.

In the figure, a sensing signal B from a fire detector (not shown) corresponding to a control unit U is supplied to input terminals WA and Wa of AND circuits GA and Ga.

In addition, if a fire occurs somewhere in the building while the passageway closure designation switch R connected to the control unit U is turned on, the signal ■ of the passageway closure designation switch R will be activated in response to the fire signal C. AND circuit GA.

It is designed to be supplied to input terminals WA and Wa of Ga.

When a fire occurs, if the detection signal B from the fire detector or the path closure designation switch R is turned on, that signal is given to the control unit of each warning area,
The input terminals WA and Wa of the AND circuits GA and Ga become [1].

Therefore, the outputs of the AND circuits GA, Ga are the terminals XA,
Xa or AND circuit GA, the other input terminal YA of Ga.

No matter what signal is given to Ya, (9) will result.

Therefore, the evacuation direction indicator H is not driven, and even if the emergency exit signal is given to the left terminal A, the signal is not sent to the right terminal a, and even if the emergency exit signal is given to the right terminal a, the left terminal That signal is never sent to A.

That is, the control units of the guarded area where the fire has occurred and the guarded area where the passage closure designation switch R is turned on are inactivated.

On the other hand, at the same time as the fire occurs, the switch Q shown in FIG. 2 is closed, and the emergency exit signal source K is transmitted to the terminal E1 corresponding to the emergency exit.
An emergency exit signal is given to E2.

This emergency exit signal is then sent to the emergency exit signal transmission line from terminals E□ and E2.

In this case, if we consider a control unit other than the fire outbreak point and the restricted area where the passage closure designation switch R is turned on, for example, the control unit U1 shown in Fig. 2, an emergency exit signal is sent to the left terminal A (Fig. 4). is given, the input terminal YA of the AND circuit GA shown in FIG. 4 becomes 0]
becomes.

Since the input terminals xA and wA are O], the output of the AND circuit GA becomes [1], and the indicator light Ha is driven to light up.

At the same time, the emergency exit signal at output terminal zA is transmitted to the control unit next to it (
(not shown), and similarly gives an evacuation guidance instruction in the direction of the nearest emergency exit, that is, in the direction opposite to the transmission direction of the emergency exit signal.

Note that when the output terminal zA becomes 0], the AND circuit G
The input terminal Xa of a also becomes 0], so no matter what signal is input to the input terminal Ya, the output terminal z of the AND circuit Ga
a is ■].

Therefore, the indicator light HA is not driven to turn on. In this case, the following should be noted.

That is, the diode DA (Da) is connected to the AND circuit Ga
The emergency exit signal at the output terminal Za (zA) of (GA) is transmitted to the terminal A (a), but the incoming emergency exit signal to the terminal A (a) is prevented from driving the indicator lamp HA (Ha) to light up. are doing.

In this way, control units U1 to UIO (Fig. 2)
operates based on the emergency exit signal given earlier by the emergency exit signal transmission line, and controls the evacuation direction indicators H1 to H1o so that the indicated direction is opposite to the direction of the nearest emergency exit, that is, the transmission direction of the emergency exit signal. .

In this case, the control units for the restricted area where the fire occurred and the restricted area where the passageway closure designation switch R was turned on are deactivated, and the emergency exit signal is transmitted bypassing the restricted area, so the evacuation direction indicators H1 to H1o instructs the evacuation direction to bypass those caution areas.

As a result, people can avoid dangerous passages and evacuate to the nearest emergency exit.

Referring again to FIGS. 1 and 2, for example, in FIG.
When a fire occurs in the warning area 2 with none of the -R1o turned on, both indicator lights H2A and H2a of the evacuation direction indicator H2 in the warning area 2 remain off.

At this time, the guard areas 3, 4, 7, and 8 are connected to the terminals E1. Evacuation direction indicators H3, H4j that indicate the direction of the emergency exit with the emergency exit signal from E2; indicator lights H for H7 and H8;
3A, H4A, H7a, and H8a only work.

Then, in the next step, the evacuation direction indicators H1, H5, H6, H9, and Hlo in the caution areas 1, 5, 6, 9, and 10 are controlled.

In other words, guard area 1 corresponds to guard area 4, guard area 6 corresponds to guard area 3, guard areas 5 and 9 correspond to guard area 8, and guard area 10 corresponds to guard area 7) (H4, U3).
t UB t Since the emergency exit signal is sent from H7, evacuation direction indicator H1 for restricted areas 1, 5, 6, 9° 10
, H5, H6, H9, Hl.

Indicator lights H1a, H5A, H6a, H0, and HloA are driven.

As a result, as shown in FIG. 5, it is possible to instruct the shortest course to the emergency exit without passing through the caution area 2 at the fire outbreak point, and it is possible to guide people to the emergency exit.

Next, if a fire breaks out in restricted area 2, and restricted area 3 is under construction, etc., and the passage closure designation switch R3 of the control unit U3 is turned on, the indicator light H2A of the evacuation direction indicator H2tHs of restricted area 2°3 is turned on. , H2a.

Both H3A and H3a remain off.

At this time, the guard areas 4, 7, and 8 are connected to the terminal E1. Indicator lights H4A, H7a of evacuation direction indicators H4, H7, H8 that indicate the direction of the emergency exit with the emergency exit signal from E2
, only H8a works.

Then, in the next step, the evacuation direction indicators H1, H6, H0, and H1o in the warning areas 1, 5, 9, and 10 are controlled.

That is, the warning area 1 is 4, the warning areas 5 and 9 are 8,
The guard area 10 is controlled by a control unit U4.
U8. Since the emergency exit signal is sent from U7, indicator lights H1a, H6A, H0a, and H1oA of H1, H5°H9, and Hlo in warning areas 1, 5, 9, and 10 are driven.

Furthermore, the guard area 6 is controlled in the next step.

Security area 6 is security area 9, 100 control unit U0. U
The emergency exit signal is sent from lo, so turn on the H6 indicator light H.
aA is driven.

As a result, as shown in FIG. 6, it is possible to indicate the shortest course to the emergency exit without passing through the warning zone 2 at the fire outbreak point and the dangerous warning zone 30 due to construction.

Note that the evacuation direction indicators H1 to H1o may be not only indicator lights (guide lights) as in the embodiment but also audio equipment.

Furthermore, in the example, only the case of fire was described;
Using a gas detector instead of a fire detector can also provide evacuation guidance in the event of a gas leak.

As described above, the evacuation guidance system of the present invention can avoid dangerous passages and guide evacuation to the nearest emergency exit.
