Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an evacuation guidance device that can appropriately guide people inside a building to evacuate.

[Prior Art] Buildings such as offices and hotels are equipped with evacuation guidance devices, so that evacuation guidance routes such as emergency exits can be displayed even in emergencies such as power outages and fires.

However, with such conventional evacuation guidance systems, when an emergency situation is detected, all the guidance devices (evacuation guidance indicators, etc.) installed in the building are immediately controlled. Even when a large number of visitors are gathered at a specific location within a building, such as a predetermined floor, only the location of an evacuation route is notified at a time. As a result, a large number of visitors may rush to a single emergency exit, making it impossible to evacuate quickly.

In this way, with conventional equipment, the number of people remaining in the building,
Since the location cannot be detected, evacuation guidance may not be appropriate, and appropriate rescue operations may not be possible or it may not be possible to determine whether rescue operations are necessary.

[Problems to be Solved by the Invention] Taking the above facts into consideration, the present invention provides an evacuation guidance device that is capable of providing appropriate evacuation guidance by ascertaining the location of entry and the number of people entering the building in the event of an emergency. The purpose is to

[Means for Solving the Problems] The evacuation guidance device according to the present invention includes a transponding card possessed by a visitor, which is equipped with a transmitter that transmits a specific code signal for self-identification, and a plurality of structures. A receiving means is installed at a location to receive the code signal of the transponding card, and in response to the transmitted confirmation signal, the location of each transponding card is ascertained by the signals from these receiving means, and each entry point is detected in the event of an emergency. It has a general calculation means for determining the optimal evacuation route for people entering the building, a display means for receiving a signal from the calculation means and notifying the evacuation route for each person entering the building, and an in-house broadcasting means for making an announcement within the building in case of an emergency. .

[Function] When a fire or the like occurs, a confirmation signal is transmitted from the general calculation means to the transponding card holder, and in response, a code signal is automatically transmitted from the transponding card, so that
It is possible to appropriately grasp the number of people entering the building in each part of the structure, make evacuation guidance announcements, and use indicator lights to indicate evacuation routes according to the number of people, thereby quickly and safely guiding the visitors to evacuate. Therefore, even when a large number of visitors are gathered in a specific area, these visitors can be appropriately dispersed and evacuated quickly and safely.

[Embodiment] FIG. 1 shows an embodiment in which the present invention is applied to an in-building central control device installed in an intelligent building.

The in-house central control device receives the code signal from the transponding card 12 and calculates the number of visitors,
It is a comprehensive centralized management system that grasps the location of visitors and automatically controls elevator operation management, indoor air conditioning control, etc. based on computer calculation results. In the Intelligent Building, visitors are required to enter the building with a transponding card 12 shown in FIG. 3 in advance. The transponding card 12 is formed, for example, from a thin board made of synthetic resin, and has a photograph 14 of the visitor affixed to its surface, and a display column 16 corresponding to the photograph 14 for displaying the name of the affiliation and the like. Transponding card 1
This transponding card 1 is on the back of 2.
A clip 18 is provided so that the item 2 can be attached to a chest pocket or the like.

The transponding card 12 has a built-in circuit shown in FIG. It is determined whether the signal from the transponding card 12 is a calling signal for the own transponding card 12, and when necessary, the signal is sent to the notifying unit 28 and the transmitting unit 3.
0 is activated and notifications and transmissions are made to the outside.

Furthermore, in this transponding card 12, the main circuit of the arithmetic unit 24 is not energized at all times, and the power switching unit 20 is activated only when the receiving unit 26 receives a call signal from the outside. By activating the main circuit of the arithmetic unit 24 using the power supply unit 22, the life of the power supply unit 22 can be extended.

As an example, the power supply section 22 can be a thin card-shaped battery having a structure in which two conductive plastic films are coated with manganese dioxide powder on one side and zinc powder on the other, stacked on top of each other with a non-woven fabric sandwiched between them. Further, as the calculation section 24, the reception section 26, the notification section 28, and the transmission section 30, for example, an IC card in which an IC device is built into a thin plastic card can be used.

The transmitter 30 can transmit a signal for identifying itself, such as a different frequency, for each transponding card 12 produced in plurality. In addition, with the same frequency, the radio (TRT) 42
The time for each transponding card 12 to respond to a polling signal from A to 42C may be made different for each transponding card 12 to identify each transponding card. The notification section 28 can issue different types of notification signals depending on the different types of reception signals received by the reception section 26. For example, when transmitting a call signal to a visitor who has a transponding card 12, a call signal to a specific room,
The output signal to the speaker may be controlled so as to emit a signal depending on the type of call, such as a call signal to an in-house telephone, by changing the tone, frequency, signal period, etc.

A switching antenna is installed at the entrance of the Intelligent Building, and the transponding card 1 is
The power switching section 2 is activated and the calculation section 24 starts operating.

The evacuation guidance device shown in FIG. 1 functions as part of the above-mentioned centralized management system. Multiple antennas 4 are installed on the ceilings and walls of hallways, stairs, etc. in the building.
0A, 40B... are installed, the code signal transmitted from the transponding card 12 is received by these antennas 40A, 40B..., and the received code signal is transmitted to radio equipment (TRT) 42A, 4.
2B... operates, and the code signal is transmitted to local radio control equipment (LRC) 44A, 44B.
. . . The code signal is transmitted to a central wireless control device (CRC) 48 via a transmission line 46 such as a local network (LAN), and the CRC 48 that receives the code signal is a building management processor (GP) that functions as a general calculation means. 50 and a distributed processing processor (DDP) 52.

In the GP 50, data processing is executed based on the code signal, such as the transmission location of the code signal, the number of card holders, etc., and the data is displayed on the display 50 as necessary.
The location of entry into the museum, the number of people there, etc. are displayed.

Note that 72 is an electronic exchange (EPBX), and in an emergency, the EPBX 72 is controlled based on commands from the GP 50 or DDP 52, so that, for example, a specific telephone line can be secured.

Additionally, the GP 50 is supplied with sensor outputs detected by disaster prevention sensors 56 installed at multiple locations within the building. As the disaster prevention sensor 56, a well-known sensor such as a fire and smoke detection sensor is used.

In the GP50, by inputting this sensor output, it is detected where in the building a fire, etc. has occurred, and when the sensor output is input, the in-building automatic broadcasting device 58 is immediately activated to broadcast information installed at multiple locations. The evacuation guidance signal is supplied to all of the speakers 60 or to the speakers at the location where the fire or the like has occurred, and is broadcast in the building.

In addition, in such an emergency, evacuation guidance indicators 64A, 64B,... installed in the hallway etc.
The lighting signal is transmitted from the DDP 52 to the CRC 48, the transmission line 46, and the indicator light controllers 62A, 62B,
It is sent via... In this case, the lighting signal is displayed on the necessary indicators 64A, 64, etc. at the location where the fire occurred.
In order to selectively supply only to TRTs 42A, 42B, .
A confirmation signal is provided to check whether the person is present in the room.

When the plurality of transponding cards receive this confirmation signal, a code signal is transmitted. Based on this, GP50 checks whether the person is in the library or in the room.

Figure 5 shows indicators 64A and 64 in case of emergency.
An example of B,... is shown. This display 64A is provided in each floor corridor, each floor branch path, stairs, etc. This includes guidance displays 66, 68 indicating different evacuation routes,
70 are provided.

In addition, a light source corresponding to these guidance displays 66, 68, and 70 is provided in this display 64A, and according to a command from the DDP 52, any one of the guidance displays 66, 68, and 70 is illuminated to illuminate each floor. It is now possible to display the optimal taxi route for each day and a different taxi route for each time.

In other words, when there are many people entering the building on each floor, these people can be dispersed and guided safely to multiple emergency exits, and in the event of a fire, the safe evacuation route can be sequentially changed depending on the progress of the fire. (In FIG. 5, the guidance display 66 is illuminated.)

Figure 2 is a flowchart showing evacuation guidance in the event of an emergency such as a fire outbreak.

The control program starts, and in step a, the presence or absence of a fire or the like is checked. This is determined based on the presence or absence of the output from the sensor 56 mentioned above. If there is an output from any of the disaster prevention sensors 56, the location of the disaster occurrence is determined in step b.
Detected by GP50 and step c
A confirmation signal is sent to all TRT42A, 42B...

Therefore, if there are visitors only in the area where the antenna 40A is installed, the transponding card 1 held by the visitor in that area
2 receives this confirmation signal, and in response, the transponding card 12 transmits a code signal. This code signal is antenna 40A
Therefore, in step d, the input status of the code signal is checked, and if no code signal is input, the display 64A installed at that location is not controlled in any way, and evacuation guidance control is performed. mode ends.

However, as shown in FIG. 1, if there are several people entering the building, the code signal is input. Along with this, evacuation guidance broadcasting starts at step f.

The content of the broadcast includes, for example, the type of disaster, the location of the disaster, etc., and if visitors follow the direction of the evacuation guide lights, they will be able to evacuate in the safest, quickest, and safest place (outside the building, (any place in the building)
Broadcast that you can evacuate.

In DDP52, the entrance location detected in step e,
An optimal evacuation route is calculated by comprehensively considering the number of visitors, the location where the disaster occurred, etc., and a control signal based on this calculates the lighting of the indicator light of the predetermined indicator 64A (step g).

After the display 64A lights up, the input state of the code signal is checked again in step h, and the whereabouts of the visitor is constantly checked. If the code signal is being input, the process returns to step e and the control operation described above is performed. is repeated.

When the visitor evacuates to a safe place, the code signal is no longer input, and the control program ends.

[Effects of the Invention] As explained above, the evacuation guidance device according to the present invention includes a transponding card held by a visitor, which is equipped with a transmitter that transmits a specific code signal for identifying the user, and a transponding card that is attached to a building. Receiving means installed at multiple locations to receive the code signals of the transponding cards, and signals from these receiving means in response to the transmitted confirmation signal are used to ascertain the location of each transponding card. It has a general calculation means for determining the optimal evacuation route for the building's occupants, a display means for receiving a signal from the calculation means and informing the evacuation route for each visitor, and an in-house broadcasting means for broadcasting the building in case of an emergency. It is possible to accurately grasp the location of the person entering the building, determine the most suitable evacuation route according to the place of entry, and control the display means for the corresponding evacuation guidance.

This allows visitors to evacuate to a safe location in a short time by simply relying on the display means to evacuate.
Damage can be kept to a minimum.

Furthermore, since the disaster situation can be ascertained through the in-house broadcast system, visitors can also take calm actions.
