This invention relates to an evacuation guidance system. The applicant for this patent filed a patent application for the evacuation guidance system that is the basis of this invention on May 31, 1975 (patent application No. 5O-662).
77) I did. In this evacuation guidance system, 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. 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 received from the opposite direction. In addition, an emergency detector such as a fire detector is installed in the passageway, and when an emergency situation occurs, the sensor at the point of occurrence emits a detection signal, and the control unit corresponding to the passageway at the point of occurrence has a signal transmission function and instructions. Stop the device control function. 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 control unit corresponding to the path at the point of occurrence. In this way, by sequentially shifting the emergency exit signal to the control unit installed corresponding to each aisle and setting the direction opposite to the direction in which the signal is transmitted as the evacuation direction, people can be directed to the emergency exit closest to the point where the emergency occurs. This is to provide evacuation guidance. Next, an evacuation guidance system, which is the basis of this invention, will be explained based on the drawings. FIG. 1 is a block diagram of an embodiment of the evacuation guidance system that is the basis of this 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 80 to S10 are installed in the warning zones 1 to 10.
and evacuation direction indicators H1 to H□. Set up. The evacuation direction indicators H1 to H1o each include a pair of indicator lights H1A, H1a-H1oA, and H1oa. Figure 2 is a control system diagram of Figure 1, with control units U1 to U.
1o are placed corresponding to each passageway in Figure 1, and each control unit is connected to each other by an emergency exit signal transmission line, and each control unit U, ~U1o is a fire detection unit installed in the passageway corresponding to its location. 81 to S1o are 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. FIG. 3 shows the basic configuration of the control units U1 to U1° shown in FIG. In the figure, the sensing signal V from the fire detector S corresponding to the control unit U is the input terminal wA of the AND circuit GA, Ga.
, wa. When a fire occurs, the detection signal V from the fire detector is given to the control unit of the warning area, and the AND circuit GA
, Ga's input terminals WA, Wa become [1]. Therefore, the outputs of the AND circuits GA, Ga are the terminals XA,
No matter what signal is applied to Xa or the other input terminals YA, Ya of the AND circuit GA, Ga.

becomes. Therefore, even if a clock pulse arrives from a clock pulse generator (not shown), the flip-flops FA and Fa are not set, and the evacuation guidance indicator H is not driven. Further, even if an emergency exit signal is given to the left terminal A, the signal is not sent to the right terminal a, and even if an emergency exit signal is given to the right terminal a, the signal is not sent to the left terminal A. That is, the control unit in the caution area where the fire occurred is 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, , E2. In this case, a control unit other than the point where the fire occurred,
For example, considering the control unit U shown in FIG. 2, when an emergency exit signal is applied to its left terminal A (FIG. 3), the output of the AND circuit GA shown in FIG. 3 becomes [1]. At this time, the clock pulse is applied to the flip-flops FA and F.
a, the output of the AND circuit Ga is

Since it is [0], only flip-flop Fa is set. When flip-flop Fa is set, relay Ra is activated and the evacuation direction indicator connected thereto is driven. At the same time, the output of the flip-flop Fa is applied to the right terminal a through the diode Da, and is sent as an emergency exit signal to the control unit adjacent to this control unit. In this way, the control units are sequentially controlled while taking timing with the clock pulse, and the evacuation direction indicators H1 to H0o are controlled.
control 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 unit of the restricted area where the fire occurred is deactivated and the emergency exit signal is transmitted bypassing the restricted area, so the evacuation direction indicators H1 to H1o bypass the restricted area and indicate the evacuation direction. Instruct. As a result, people are not directed to the location of the fire. Referring again to Figures 1 and 2, for example, in Figure 1, when a fire occurs in warning area 1, both indicator lights HIA and H1a of the evacuation direction indicator H□ in warning area 1 are turned off. At this time, the alert areas 3, 4, 7, and 8 are equipped with evacuation direction indicators H3, H4, H7, and H that indicate the direction of the emergency exit using the emergency exit signal from the terminal E0°H2 corresponding to the emergency exit.
Only the 8 indicator lights H3A, H4A, H7a, and H8a operate. Then, in the next step, evacuation direction indicators H2, H5, H6, H9, and Hl for caution areas 2, 5, 6, 9, and 10. is controlled. That is, the control units U3 and U3 correspond to the control area 2, the control area 3, the control area 6, the control area 3, the control areas 5 and 9, the control area 8, and the control area 10 to the control area 7, respectively.
, H8, and H7 will send emergency exit signals, so use the evacuation direction indicators H2, H in restricted areas 2, 5, and 6°9.10.
5, H6, H9゜Hlo indicator light H2A) H5A
t H6a, Hga, and Hlo A are driven. As a result, as shown in Fig. 4, 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 to guide people to the emergency exit. However, in this case, when the width of the emergency exits and passageways inside the building is not uniform, the inside of the building is divided into two parts as shown by the dotted line in Figure 4, and the people inside are guided to the first and second emergency exits respectively. As a result, a large number of people gather in narrow emergency exits and passageways, resulting in a high density of people and the problem that evacuation speed rapidly decreases and smooth evacuation is not possible. Therefore, an object of the present invention is to provide an evacuation guidance system that allows people to evacuate in the shortest possible time. In summary, the evacuation guidance system of the present invention includes an evacuation direction indicator provided in an evacuation guidance path, system wiring corresponding to the evacuation guidance path, selectively transmitting an emergency exit signal in one direction, and A control unit that instructs and drives a corresponding evacuation direction indicator in a direction opposite to the emergency exit signal transmission direction, a plurality of emergency exit equivalent locations provided at locations corresponding to the emergency exits in the system wiring of the control unit, and supplies an emergency exit signal. The emergency exit signal source is provided with a plurality of emergency exit signal sources connected to the location corresponding to the emergency exit, and a timing means for activating the emergency exit signal source at a predetermined timing when an emergency situation occurs. A control system diagram of an embodiment of the present invention is shown in FIG. This control system diagram shows an AND circuit Gb and a shift register T.
The control system diagram is the same as the control system diagram in FIG. 2 except that . That is, the AND circuit Gb is opened by the fire signal given from the fire signal source F via the switch Q1 which closes at the same time as the fire occurs, and the clock pulses from the clock pulse generator P are input to the shift register T, and each control unit U1 ~ Also supplied to UIO. This shift register T operates at the rising edge of the clock pulse as shown in Fig. 6a, and sequentially outputs emergency exit signals from stage numbers 1 to n as shown in Fig. 6c and d. It is supplied to the terminal E1 corresponding to the emergency exit 1 and the terminal E2 corresponding to the emergency exit 2 with a narrow evacuation route. Further, the control units U1 to U1o are configured to operate at the falling edge of the clock pulse. Before the fire occurs, the shift register T has been reset and no clock pulses are given to the control units U1 to U1o, so they stop operating. When a fire occurs, switch Q1 closes and circuit Gb
A clock pulse appears at the output of and is sent to the clock input of the shift register T and to each control unit U1 to U1o. At this time, the data input of the shift register T has already been given (+V), so every time a clock is input, an emergency exit signal synchronized with the clock pulse is output to the output terminal of the shift register T as shown in Figure 6. be done. This signal is sent to terminals E1 and E2 corresponding to the emergency exits in Figure 5.
supplied to For example, in FIG. 5, when a fire occurs in the warning area 1 corresponding to the control unit U1, a clock pulse is output from the AND circuit Gb, and an emergency exit signal is set in the stage number 1 of the shift register T, and the emergency exit signal is output from there. It is sent to terminal E1, which corresponds to the wide emergency exit of the evacuation route. This emergency exit signal is sent to control unit U3. Sent to U7,
The evacuation direction indicators controlled by these control units U3 and U7 indicate the direction of the first emergency exit. And the emergency exit signal is from control unit U3 to U2 7U6
and from the control unit U7 to Ulo. Next, when a clock pulse numbered 2 is applied to the shift register T from the AND circuit Gb, emergency exit signals are set in stage numbers 1 and 2 of the shift register T. Then, the control units U2, U6 and UTO operate, and the evacuation direction indicators controlled by the control units U2, U6 and ULO respectively indicate the direction opposite to the arrival direction of the emergency exit signal. Then from control unit U2 to Ul. An emergency exit signal is sent to U5 and from control unit U6, Ulo to U. Next, when the third clock pulse is given to the shift register T from the AND circuit Gb, the emergency exit signal is set to stage numbers 1, 2, and 3 of the shift register T, and the emergency exit signal from stage number 3 is sent to the control units U4 and U8. Sent. The evacuation direction indicators controlled by the control units U4 and U8 indicate the direction opposite to the direction of arrival of the emergency exit signal. At the same time the control unit U,. When U9 operates, the evacuation direction indicator of the control unit U5 instructs the direction of the control unit U2, and the control unit U9 instructs the direction of the control units U6 and U1o. At this time, the control unit U1 is also controlled, but since the control unit U1 is the control unit at the location where the fire occurred, it is inactivated and does not operate. As a result of controlling the evacuation direction indicator in this way,
As shown in the figure, evacuation direction indicators in a wide area within the building indicated by dotted lines instruct people to evacuate to the first emergency exit with a wide evacuation route. Therefore, most of the people in the building evacuate through the first emergency exit, which has a wide evacuation route, and a small number of people evacuate through the second emergency exit, which has a narrow evacuation route. As a result, the density of people evacuating from the first and second emergency exits is averaged, and evacuation is performed smoothly. FIG. 8 is a block diagram of a main part of another embodiment of the present invention, in which the parallel outputs of the shift register T shown in FIG. 5 and terminals E1. E2 can be selectively connected using a pin board J. With this configuration, if the location where people are concentrated changes from day to day (for example, a bargain sale venue at a department store)
But it can be easily rearranged. As described above, the evacuation guidance system of the present invention includes an evacuation direction indicator provided in an evacuation guidance path, system wiring corresponding to the evacuation guidance path, and selectively transmitting an emergency exit signal in one direction. a control unit that instructs and drives the corresponding evacuation direction indicator in a direction opposite to the emergency exit signal transmission direction; a plurality of emergency exit equivalent locations provided at locations corresponding to the emergency exits in the system wiring of the control unit; Since the emergency exit signal source is provided with a plurality of emergency exit signal sources connected to the point corresponding to the emergency exit and a timing means for activating the emergency exit signal source at a predetermined timing when an emergency situation occurs, it is possible to evacuate people at an optimal time. can. Furthermore, when the timing means is constructed from a shift register, timing can be easily adjusted.
