By specifying an individual with such a display function, it is possible to grasp the presence of a person with difficulty in walking separately from a healthy person, and to obtain information useful for evacuation activities.

  Next, a specific operation of the evacuation support facility according to the first embodiment having the technical features described above will be described in detail with reference to FIG. FIG. 1 is a layout diagram showing a part of one floor in a building for explaining an evacuation support facility according to Embodiment 1 of the present invention.

  The layout of the evacuation support facility shown in FIG. 1 includes a corridor 1, each room 2, a temporary evacuation area 3 that is a temporary shelter, an ancillary room 4 provided in front of a vertical evacuation route, and an evacuation area 3 and an ancillary room 4. Are included as a balcony 5 serving as a horizontal evacuation route, an emergency elevator 11 serving as a vertical evacuation route, and an evacuation staircase 12.

  Moreover, in FIG. 1, the entrance / exit 20 of each room 2 and the other five entrances 21-25 are arrange | positioned. Further, in order to perform entrance / exit management or occupancy management in the temporary evacuation area 3, the information of the identification tag possessed by the individual is not contacted to each of the entrances 20 and the other entrances 21 to 25 of each room. RFID sensors 27, 27 (1) to 27 (5) that are reading units that are read in the above are provided, and a monitoring camera 28 is provided in the hallway 1. Furthermore, an occupancy indicator 29 indicating the occupancy status is provided outside the entrance / exit 20 portion of each room 2.

Based on the configuration of FIG. 1, requirements A to E will be specifically described.
(1) About Requirement A (Temporary Evacuation Area 3) The temporary evacuation area 3 is connected to the corridor 1 which is a horizontal evacuation route via the entrance 21 and can enter and exit from the corridor 1, and via the entrance 22 It can be connected to the balcony 5 to enter and exit from the balcony 5. As shown in FIG. 1, the temporary evacuation area 3 is provided on a part of the floor, and is provided at a position accessible to the emergency elevator 11 or the evacuation stairs 12 that serves as an evacuation route in the vertical direction of the building. It has been.

  Furthermore, the temporary evacuation area 3 is covered with a fire wall W, and a structure that can protect people temporarily evacuated in the temporary evacuation area 3 from a fire is adopted. And it is desirable for the temporary evacuation area 3 to be configured to be able to block flame, smoke, or toxic gas generated by a fire by being partitioned by the fire wall W. The size of the temporary evacuation area 3 is appropriately determined in consideration of the space occupied by disaster vulnerable persons preliminarily assumed in a fire fighting plan or the like. In this manner, by temporarily securing the temporary evacuation area 3 as a protective space in a part of the floor specified in advance, temporary evacuation in the horizontal evacuation can be reliably performed.

  Further, the temporary evacuation area 3 is provided at a position accessible to the emergency elevator 11 or evacuation stairs 12 that is a vertical evacuation route, and a protected route that leads to the emergency elevator 11 or evacuation stairs 12 that is a vertical evacuation route. For example, it is possible to reliably protect disaster victims from fire until evacuation from the emergency elevator 11 becomes possible.

  Further, although not shown, a smoke CO combined sensor with a sound alarm that operates when the temporary evacuation area 3 is affected by a fire can be installed in the temporary evacuation area 3. When the smoke CO combined sensor with voice alarm is activated, the people who are temporarily evacuated in the temporary evacuation area 3 are informed immediately of the situation that evacuation is necessary. ) Can be prioritized to be prompted to escape from the temporary evacuation area 3.

(2) Requirements B and C (entrance / exit identification unit, monitoring unit) The shared temporary evacuation area 3 is used as a temporary refuge place for evacuees in the event of a fire. Therefore, in order to smoothly carry out evacuation activities in the event of a fire, it is important to accurately grasp the occupant information in the temporary evacuation area 3 of evacuees (particularly those who are vulnerable to disasters).

  It is desirable that the RFID sensors 27 (1) and (2) corresponding to the entrance / exit identification units provided at the entrances 21 and 22 can detect the direction of passage at the entrances 21 and 22. As long as the direction of passage can be detected and an individual can be identified without contact, the present invention is not limited to occupancy management composed of a combination of the RFID sensors 27 (1) and (2) and the recognition tag (RFID tag). For example, a camera is installed in place of the RFID sensors 27 (1) and (2) at the entrances 21 and 22, and an individual is identified by performing face recognition processing on an image captured by the camera, and further moved. By determining the direction, it is also possible to determine whether the person has entered or left the temporary evacuation area 3.

  Further, even if the RFID sensor 27 (1), (2) detects the information of the recognition tag through which the RFID sensor 27 (1), (2) passes and the direction of passage cannot be grasped, the number of passes for each detected recognition tag can be calculated. It is possible to perform occupancy management by counting, and determining that the room is present if the counted value is an odd number and that the person is leaving if the counted value is an even number.

  A person who is not registered in the database of the monitoring unit, for example, difficult to evacuate by installing a camera in place of the RFID sensors 27 (1) and (2) and performing image processing on an image captured by the camera. It is also possible to ascertain the situation and the number of people who are in the room, who support the evacuation of the person. It is also possible to predict whether or not the person is a person with difficulty in evacuation based on gender, age, walking motion, and the like. Then, it becomes possible to grasp those who have difficulty in evacuation who are present in the temporary evacuation area 3 at a disaster prevention center or the like where the monitoring unit is installed, and to perform appropriate evacuation support.

The RFID sensor 27 (1), (2), or a camera installed in place of them is not described in detail, but is connected to the transmission line between the fire detector and the fire receiver and is similar to the fire sensor and the like. In addition, the fire receiver may collect information from the RFID sensor 27 (1), (2), or a camera installed in place of them, and when a fire breaks out, based on the result, an overall information display to be described later You may control based on the control signal from a fire receiver so that the display by a vessel may be started.

  In the following, for simplification of explanation, the evacuees enter the temporary evacuation area 3 from the corridor 1 via the entrance 21 and exit from the temporary evacuation area 3 to the balcony 5 via the entrance 22. The occupancy management will be described using a case as an example.

  A recognition tag (RFID tag) in which personal identification information is stored is distributed in advance to those who should perform personal identification. The RFID sensor 27 (corresponding to the entrance / exit identification unit) provided in the vicinity of the entrance / exit 21 is stored in the RFID tag when the person entering the temporary evacuation area 3 has the RFID tag. Read personal identification information without contact. Similarly, an RFID sensor 27 (corresponding to an entrance / exit identification unit) provided in the vicinity of the entrance / exit 22 is stored in the RFID tag when a person leaving the temporary evacuation area 3 has the RFID tag. Read personal identification information without contact.

  Then, the monitoring unit (not shown in FIG. 1) identifies an individual who has entered the temporary evacuation area 3 based on the personal identification information read by the RFID sensor 27 provided in the vicinity of the entrance 21. The occupant information in the evacuation area 3 is updated. Similarly, the monitoring unit identifies an individual who has left the temporary evacuation area 3 based on the personal identification information read by the RFID sensor 27 provided in the vicinity of the entrance 22, and Update occupant information for.

  The monitoring unit counts the personal identification information read by the RFID sensors 27 (3) to 27 (5) installed in the vicinity of the entrances 23 to 25 in a time series, so that the inside of the temporary evacuation area 3 In addition to occupant information, it is also possible to identify an individual who has escaped via an evacuation route. That is, it is possible to specify the evacuation route and the current location for each individual by counting and displaying the RFID sensors from which the personal identification information is read in time series for each individual.

  Although not described in detail, the RFID sensor 27 is connected to a transmission line between a fire detector or the like and a fire receiver, and the fire receiver may collect information from the RFID sensor 27 in the same manner as the fire detector or the like. Based on the result, on / off of the occupancy indicator 29 in each room may be controlled based on a control signal from the fire receiver.

(3) Requirement D (individual occupancy status identification unit) When an RFID sensor 27 (corresponding to the individual occupancy status identification unit) is also provided in the vicinity of each entrance / exit 20 of each room 2, a monitoring unit Can generate and update the occupant information of each room 2 in each room 2 based on the personal identification information of the recognition tag (RFID tag) read by these RFID sensors 27. .

  As a result, the monitoring unit can identify and identify persons who have not yet reached the temporary evacuation area 3 and are still out of the room 2 and who are in the room. In addition, the monitoring unit can grasp the situation where the evacuees who have left the room 2 have not reached any of the routes for evacuation, for example, the temporary evacuation area 3, the attached room 4, or the evacuation stairs 12. For example, an evacuee who has left the room 2 is late to escape because the evacuee has not passed the RFID sensors 27 (1) and 27 (3) even after a predetermined upper limit time has elapsed. Or it can be judged that it is missing. As described above, the monitoring unit is based on the detection results by the RFID sensors 27 (1) and 27 (2) as the entrance / exit identification unit and the detection results by the RFID sensor 27 as the individual occupancy status identification unit. By collecting the identification information in time series, the evacuation situation and the latest location can be displayed for each individual. And an evacuee who has left the room 2 at a disaster prevention center or the like where a monitoring unit is installed can be grasped and appropriate evacuation support can be performed.

  The RFID sensor 27 provided at the entrance / exit 20 is preferably one that can detect the direction passing through the entrance / exit 20. As long as the direction of passage can be detected and an individual can be identified without contact, the present invention is not limited to occupancy management consisting of a combination of the RFID sensor 27 and the recognition tag. For example, a camera is installed in place of the RFID sensor 27 at the entrance / exit 20, an individual is identified by performing face recognition processing on an image captured by the camera, and the person is further identified by determining the moving direction. It is also possible to determine whether the user has entered or left the room 2.

  In addition, even if the RFID sensor 27 detects the information of the recognition tag that passes, and the direction of passage cannot be grasped, the number of times of passage for each detected recognition tag is counted. It is possible to perform occupancy management by determining that the room is occupying an odd number and leaving the room if the number is even.

  A person who is not registered in the database of the monitoring unit, for example, a person who has difficulty in evacuation, by installing a camera in place of the RFID sensor 27 provided at the entrance 20 and performing image processing on an image captured by the camera. It is also possible to ascertain the situation and the number of people who are present in the room. It is also possible to predict whether or not the person is a person with difficulty in evacuation based on gender, age, walking motion, and the like. And in the disaster prevention center etc. in which the monitoring part was installed, the person who has difficulty in evacuation in the room 2 can be grasped, and appropriate evacuation support can be performed.

  Further, the monitoring unit identifies from the result of the occupant information updated based on the RFID sensor 27 by turning on the occupancy indicator 29 when there is a person in the room 2. Can be displayed. As a result, in the event of a fire, the rescue worker can quickly grasp the occupant information in each room 2, which helps to facilitate evacuation activities in the event of a fire.

(4) About Requirement E (Overall Information Display) The monitoring unit displays the occupant information in the temporary evacuation area 3 updated based on the identification result by the entry / exit identification unit and the identification result by the individual occupancy status identification unit. The occupant information of each room 2 updated based on the information can be displayed on the general information display 30 provided near the temporary evacuation area 3.

  Here, the general information display 30 can be installed in the temporary evacuation area 3 or one or both outside the temporary evacuation area 3. In FIG. 1, the general information display 30 (1) is installed on the wall surface of the ancillary room 4 outside the temporary evacuation area 3, and the general information display 30 (2) is installed on the wall surface in the temporary evacuation area 3. The state is illustrated.

  Further, the information displayed on the general information display 30 is not limited to the occupant information updated by the monitoring unit, but the occupancy status can be displayed in accordance with the floor layout display as shown in FIG. It can also be displayed.

  The occupant information generated by the monitoring unit can be transmitted not only to the building management center but also to other security centers. Therefore, in the event of a fire, it is possible to accurately grasp occupant information that identifies an individual even outside.

  The general information display 30 may be controlled so as to start display from a monitoring unit that has received a fire signal from a fire receiver not described in detail when a fire occurs. Further, the general information display 30 may display information transmitted from a fire receiver that will not be described in detail. At this time, the fire receiver plays the role of a monitoring unit, and the entrance / exit is performed. The fire receiver collects information from the identification unit and creates occupant information. The same information as the temporary evacuation area is displayed in the disaster prevention center.

  As described above, according to the first embodiment, it is possible to identify and manage the occupancy status of the temporary evacuation area that is a temporary refuge place for disaster vulnerable persons. As a result, it is possible to realize an evacuation support facility capable of facilitating evacuation activities in consideration of vulnerable people in the event of a fire.

  In addition, by managing the occupancy status of each room other than the temporary evacuation area, it is possible to identify and accurately grasp the status of the people left behind on the entire floor or the entire building, and further evacuate activities.
