  The present invention will be described in detail with reference to the accompanying drawings. In each drawing, the same or corresponding parts are denoted by the same reference numerals. The overlapping description will be simplified or omitted as appropriate.

Embodiment 1 FIG.
FIG. 1 is a diagram showing a configuration of an entrance / exit management system according to Embodiment 1 of the present invention. FIG. 2 is a plan view for explaining the function of the entrance / exit management system according to Embodiment 1 of the present invention. FIG. 2 shows an example of the interior of a building equipped with the entrance / exit management system.

  The main part of the entrance / exit management system is composed of the center device 1 and the plurality of local controllers 2. The local controller 2 is connected to the center device 1 via a predetermined communication line 3. The local controllers 2 are connected to each other (to other local controllers 2) via the communication line 3.

  In buildings equipped with this entrance / exit management system (entire or part of a building or group of buildings), lock it in the entrance / exit of a room where you want to restrict entry / exit to a designated person or a passage where you want to restrict access to a designated person. A door 5 with a device 4 is installed. The door 5 is a door provided for restricting passage of a predetermined place. The lock device 4 is composed of, for example, an electric lock or an electronic lock.

  The local controller 2 in the system may be provided for each door 5 or may be provided for a plurality of doors 5. Further, only some local controllers 2 in the system may be provided corresponding to one door 5, and the other local controllers 2 may be provided corresponding to a plurality of doors 5.

In addition to the lock device 4, a receiver 6 and a notification device 7 are connected to the local controller 2.
The receiver 6 and the notification device 7 are provided for each door 5. The receiver 6 and the notification device 7 are installed near the corresponding door 5 (for example, a wall surface adjacent to the door 5). The receiver 6 and the notification device 7 may be configured as one device. For example, the notification device 7 may be built in the receiver 6.

  The receiver 6 is a device for receiving ID information from the IC tag 8 (not shown in FIG. 1). The ID information is information for specifying the IC tag 8 (or the owner of the IC tag 8). The receiver 6 receives ID information from the IC tag 8 existing in a predetermined detection range 9 (not shown in FIG. 1). When receiving the ID information from the IC tag 8, the receiver 6 outputs the received ID information to the local controller 2 together with device information for specifying the own device.

  The notification device 7 is for reporting predetermined information to a person around the door 5. The notification device 7 is composed of, for example, a speaker.

The local controller 2 includes information control means 10, storage means 11, authentication means 12, lock control means 13, determination means 14, measurement means 15, and warning control means 16. In addition, about the local controller 2 on the right side of FIG. 1, description of each means shown to 10 thru | or 16 is abbreviate | omitted.
The information control means 10 controls transmission / reception of information in the local controller 2.

  In the storage means 11, information of a person who is permitted to pass through the door 5 (passer permitted) assigned to the local controller 2 is stored for each door 5 (receiver 6). For example, the storage unit 11 includes ID information (personal information) and device information as authentication data. In other words, the ID information of the IC tag 8 assigned to the permitted person (hereinafter, also simply referred to as “permitted person ID information”) is registered in advance in the storage unit 11 for each door 5 (receiver 6). ing.

  The authentication unit 12 determines whether the person (passerby) who is going to pass through the door 5 is a passer. Specifically, when the information control unit 10 receives the ID information and the device information from the receiver 6, the authentication unit 12 uses the ID information received by the receiver 6 as the person permitted to pass through the door 5 (receiver 6). Whether the ID information is registered in the storage unit 11 is determined. When the ID information received by the receiver 6 matches the registered ID information, the authentication unit 12 determines that the passerby who carries the IC tag 8 is a passer of the door 5. .

  The lock control means 13 controls the lock device 4. At normal time, the lock control means 13 performs normal control. In the normal control, the lock control means 13 basically locks the lock device 4 and prevents the door 5 from being opened. When the authentication means 12 determines that the passer is a passer, the lock control unit 13 allows the passerby who carries the IC tag 8 to pass, and the lock device 4 of the corresponding door 5 is locked. To unlock. When normal control is implemented, employees who are permitted to pass in advance, such as employees, will be automatically determined to be allowed to pass if they carry their IC tag 8 and approach the receiver 6. The door 5 is opened (or the corresponding door 5 is openable).

Based on the ID information received by the receiver 6, the determination unit 14 performs a predetermined determination regarding the passage of a place where passage is restricted (including entry / exit to a room where entry / exit is restricted). For example, the determination unit 14 determines whether the IC tag 8 (who carries the vehicle: that is, the person who is not allowed to pass) who is not permitted to pass is allowed to pass through the restricted passage based on the ID information received by the receiver 6. Determine whether or not. Further, the determination unit 14 determines whether or not the IC tag 8 that is not permitted to pass has passed through the restricted traffic location based on the ID information received by the receiver 6.
Hereinafter, the function of the determination unit 14 will be described in detail with reference to the example shown in FIG.

  In FIG. 2, reference numeral 18 denotes a room in which entry / exit is restricted to a predetermined person (for example, some employees). Reference numeral 19 denotes a passage adjacent to the room 18. A door 5 is provided at the entrance of the room 18. The door 5 is unlocked and locked by the locking device 4. A receiver 6 and a notification device 7 are installed in the vicinity of the door 5.

  When the IC tag 8 is present within the detection range 9 of the receiver 6, the determination unit 14 determines whether the IC tag 8 exists outside the room 18 (that is, the passage 19 side from the door 5), or And a function of determining whether or not it exists inside the room 18 (the room 18 side of the door 5).

In order to realize such a function, the receiver 6 includes, for example, an antenna 6a (first receiving means) and an antenna 6b (second receiving means). The antenna 6 a receives the ID information from the IC tags 8 existing outside the room 18 among the IC tags 8 existing within the detection range 9. The antenna 6 b receives the ID information from the IC tag 8 existing inside the room 18 among the IC tags 8 existing in the detection range 9. When the antenna 6 a receives the ID information, the determination unit 14 determines that the IC tag 8 exists outside the room 18. In addition, when the antenna 6b receives the ID information, the determination unit 14 determines that the IC tag 8 exists inside the room 18.
The configuration of the receiver 6 is not limited to the above.

As an example, consider a case where a passer-by A shown in FIG.
When the passer A (the IC tag 8 carried by) enters the detection range 9 of the receiver 6 in the passage 19, the ID information of the IC tag 8 is received by the antenna 6a. Thereby, the determination means 14 determines that the passerby A (the IC tag 8 carried by the person) is about to enter the room 18. Thereafter, when the passer-by A passes through the doorway and enters the room 18, the ID information of the IC tag 8 to be carried is received by the antenna 6b. Accordingly, the determination unit 14 determines that the passer A (the IC tag 8 carried by the person) has entered the room 18.

  When the passer-by B shown in FIG. 2 exits from the room 18 to the passage 19, when the passer-by B (the IC tag 8 carried by the person) enters the detection range 9 of the receiver 6 in the room 18, the IC tag 8 ID information is received by the antenna 6b. Thereby, the determination means 14 determines that the passer-by B (the IC tag 8 carried by the person) is about to leave the room 18. Thereafter, when the passer-by B passes through the entrance and exits the room 18, the ID information of the IC tag 8 to be carried is received by the antenna 6a. Accordingly, the determination unit 14 determines that the passer-by B (the IC tag 8 carried by the person) has left the room 18.

  By considering the reception results of both the antennas 6a and 6b, it can be determined more accurately whether the IC tag 8 is about to enter the room 18 or has left the room 18. For example, when the antenna 6a receives the ID information and the antenna 6b receives the same ID information within a predetermined time immediately before the determination unit 14 receives the ID information, the IC tag 8 having the ID information It is determined that the user has left the room 18. On the other hand, when the antenna 6a receives the ID information and the antenna 6b does not receive the same ID information within the predetermined time immediately before the determination unit 14 receives the ID information, the IC tag 8 having the ID information Determine that you are about to enter room 18.

  The measuring means 15 measures the time during which the IC tag 8 (the person who carries it) stays in a room (that is, a restricted area) where entry / exit is restricted to a predetermined person. For example, in the example shown in FIG. 2, when the determining unit 14 determines that the IC tag 8 has entered the room 18, the measuring unit 15 starts measuring the staying time for the IC tag 8. Moreover, the measurement means 15 will complete | finish the measurement of the said stay time, if the determination means 14 determines that the IC tag 8 came out of the room 18. FIG. The information control unit 10 transmits information related to the stay time measured by the measurement unit 15 to the center device 1. The center device 1 manages the received stay time information as occupancy information for each IC tag 8 (ID information). For example, as occupancy information, ID information, information for identifying the room where the user stayed, and the staying time are associated and stored.

  The warning control means 16 is for giving a predetermined warning. For example, when a predetermined condition is established, the warning control means 16 makes an announcement from the notification device 7 and notifies a person near the door 5 of the predetermined content. Further, the warning control means 16 makes a predetermined report to the center apparatus 1 via the information control means 10. The center device 1 manages the received notification as an alarm history for each IC tag 8 (ID information).

In addition to the lock device 4, the receiver 6, and the notification device 7, a fire detection device 17 is connected to some local controllers 2.
The fire sensing device 17 senses heat and smoke, for example, and detects the occurrence of a fire. When the fire detection device 17 detects the occurrence of a fire, the fire detection device 17 outputs fire occurrence information to the connected local controller 2. In the local controller 2 that directly receives the fire occurrence information from the fire detection device 17, the information control means 10 distributes the fire occurrence information to the center device 1 and other local controllers 2.

  The fire detection device 17 is shown as an example of a device (disaster detection device) that detects the occurrence of a disaster. When this system is provided with another type of disaster detection device, control similar to the control in the present embodiment may be performed based on the disaster occurrence information output from the disaster detection device.

  When the local controller 2 receives the fire occurrence information from the fire detection device 17, the normal control for restricting traffic to a predetermined person is terminated and evacuation control for evacuating the person inside the building to the outside of the building is started. .

In the evacuation control, for example, the lock control unit 13 always holds the lock device 4 in an unlocked state. Thereby, the person in the building can freely pass through the building without being restricted by the door 5. Even after the evacuation control is started, some of the lock devices 4 may request authentication by the authentication means 12 for unlocking, as in the case of the normal control. Moreover, about some locking devices 4, you may control unlocking | locking and locking of the locking device 4 according to a passing direction, elapsed time, etc. FIG.
Specific contents when the evacuation control is performed will be described later.

The center device 1 manages each local controller 2.
The center device 1 has a function of newly registering ID information. For example, when new registration information is input from a predetermined input device (not shown), the center device 1 updates internal ID information and device information in accordance with the input new registration information. The center device 1 distributes the new registration information to the corresponding local controller 2. The local controller 2 that has received the new registration information from the center device 1 rewrites the storage contents of the storage unit 11 based on the received new registration information, and updates the information on the permitted person.
The center device 1 manages traffic authority, occupancy information, and alarm history.

  Next, the operation of the entrance / exit management system (particularly, the operation after the occurrence of a fire is detected) will be specifically described with reference to FIG. FIG. 3 is a flowchart showing the operation of the entrance / exit management system according to Embodiment 1 of the present invention.

  In the local controller 2, the information control means 10 determines whether or not the fire occurrence information is received from the fire detection device 17 (S101). If the fire detection device 17 does not detect the occurrence of a fire, the information control means 10 does not receive the fire occurrence information (No in S101). In such a case, the local controller 2 performs normal control (S102). When the normal control is performed, the lock control unit 13 controls the lock device 4 based on the authentication result of the authentication unit 12, for example.

  When detecting the occurrence of a fire, the fire detection device 17 transmits fire occurrence information to a specific local controller 2 (Yes in S101). In the local controller 2 that directly receives the fire occurrence information from the fire detection device 17, the information control means 10 informs the center device 1 and the other local controller 2 that the fire occurrence information (or fire occurrence information has been received). Information).

  When receiving the fire occurrence information (or information to that effect), the local controller 2 ends the normal control and starts predetermined evacuation control (S103). When the evacuation control is started, the lock control means 13 keeps the lock device 4 in an unlocked state, for example.

  Even after the evacuation control is started, the receiver 6 receives the ID information from the IC tag 8 existing in the detection range 9. When receiving the ID information from the IC tag 8, the receiver 6 outputs the received ID information and its own device information to the local controller 2. In the local controller 2, after the fire occurrence information is received, when the information control means 10 receives the ID information from the receiver 6, the determination means 14 performs a specific determination that is not performed during normal control.

  For example, in the example shown in FIG. 2, when the information control unit 10 receives ID information from the receiver 6 after the evacuation control is started, the determination unit 14 determines that the IC tag 8 having the ID information is outside the room 18. Whether it exists in the room 18 or in the room 18. This determination is made based on, for example, whether the ID information is received by the antenna 6a (S104). When the antenna 6a receives the ID information (Yes in S104), the determination unit 14 determines that the IC tag 8 (person who carries it) is about to enter the room 18.

  In the local controller 2, when the information control means 10 receives the ID information from the receiver 6 after the evacuation control is started, the authentication means 12 confirms that the IC tag 8 is permitted to enter the room (that is, the passerby). (S105). Even if the IC tag 8 permitted to enter the room (the person carrying it) enters the room 18 in the event of a fire, there is no particular problem. For this reason, if the ID information received by the receiver 6 in S104 matches the registered ID information (Yes in S105), the local controller 2 ends the process.

  On the other hand, while the evacuation control is being performed, for example, anyone can open the door 5 for entering the room 18. For this reason, when the ID information received by the receiver 6 in S104 does not match the registered ID information (No in S105), the determination unit 14 determines that the IC tag 8 that is not permitted to enter the room (person who carries it). Determines that there is a risk of entering the room 18. In such a case, the warning control means 16 gives a predetermined warning (S106). For example, the warning control means 16 notifies the notification device 7 corresponding to the receiver 6 that received the ID information in S104 that entry is not permitted.

  In S104, when the antenna 6a receives the ID information from the IC tag 8 that is not permitted to enter the room (No in S105), the determination unit 14 determines whether the antenna 6a no longer receives the ID information ( S107). When the IC tag 8 (the person carrying it) is out of the reception range of the antenna 6a (part of the detection range 9), the antenna 6a does not receive the ID information (Yes in S107). In such a case, the determination unit 14 determines whether or not the IC tag 8 (the person who carries the ID: the person not permitted to enter the room) having entered the ID information has entered the room 18 (S108).

  When the IC tag 8 (person carrying it) passes through the entrance / exit of the room 18 from the passage 19 side, the ID information received by the antenna 6a in S104 is received by the antenna 6b immediately after S107. For this reason, when the antenna 6b receives the ID information in S108, the determination means 14 determines that the IC tag 8 that is not permitted to enter the room (the person who carries the person: the person who is not allowed to enter the room) has entered the room 18. (Yes in S108).

  In such a case, the warning control means 16 issues a warning having a content different from the warning given in S106. For example, the warning control means 16 notifies the center device 1 (S109). The center device 1 updates the alarm history based on the received notification information.

  If the IC tag 8 (the person who carries it) simply passes in front of the room 18, the ID information of the IC tag 8 is not received by the antenna 6b. For this reason, if the ID information that is no longer received by the antenna 6a in S107 is not received by the antenna 6b after that, the determination means 14 determines that the IC tag 8 (who carries the entry is not permitted to enter the room: the person who is not allowed to enter the room) ) Is not in the room 18 (No in S108). In such a case, the warning control means 16 stops the warning started in S106 (S110).

  If it is determined in S108 that the unauthorized person has entered the room, the warning started in S106 is continued thereafter. In such a case, for example, when the determination unit 14 subsequently determines that the person not permitted to enter the room has left, the warning control unit 16 stops the warning.

  If it is determined in S108 that the IC tag 8 that is not permitted to enter the room has entered the room 18, the measuring means 15 measures the time during which the IC tag 8 stays in the room 18. The measuring means 15 ends the stay time measurement when the IC tag 8 leaves the room 18. The information control means 10 transmits the measurement result to the center apparatus 1 when the measurement means 15 finishes the measurement of the staying time.

  With the entrance / exit management system having the above configuration, when a fire occurs in the building, warning and guidance can be appropriately performed using the receiver 6 installed in the vicinity of the door 5.

  For example, when a person in a building is evacuated due to a fire, if an unauthorized person tries to enter a room where entry / exit is restricted to a specified person, the unauthorized person must enter the door. Just approaching 5, the notification device 7 notifies that entry is not permitted. For this reason, it is possible to prevent fraudulent acts that take advantage of confusion.

  Further, when a person who is not permitted to enter a room enters a room where entry / exit is restricted to a predetermined person after the occurrence of a fire, a predetermined report is sent to the center apparatus 1. Further, the notification (warning) from the notification device 7 is continued even after the person who is not permitted to enter the room enters the room. For this reason, fraud can be detected early and damage can be minimized.

Embodiment 2. FIG.
In the present embodiment, a configuration for providing appropriate guidance to an evacuated person using the entrance / exit management system configured as described above will be described.

In the entrance / exit management system according to the present embodiment, in addition to the configuration shown in FIG. 1, the center apparatus 1 is provided with a device determination means (not shown). The device determination means has a function of determining whether or not each device is operating normally. Each local controller 2 includes an evacuation route determination unit (not shown). The evacuation route determination means has a function of determining whether or not the evacuation destination is closed when a fire occurrence is detected by the fire detection device 17 and evacuation control is performed.
Other configurations are the same as those in the first embodiment.

  In the following, the functions of the entrance / exit management system (particularly, the operation after the occurrence of a fire is detected) will be specifically described with reference to FIGS. FIG. 4 is a plan view for explaining the function of the entrance / exit management system according to Embodiment 2 of the present invention. FIG. 4 shows an example of the inside of a building provided with the present entrance / exit management system. FIG. 5 is a flowchart showing the operation of the entrance / exit management system according to Embodiment 2 of the present invention.

  In FIG. 4, reference numerals 20 and 21 denote passages in the building, and reference numerals 22 to 24 denote rooms that can be directly accessed from the passage 20. A door 5 with a lock device 4 is installed at each entrance for entering and exiting the rooms 22 to 24 from the passage 20. 25 and 26 are rooms that can be directly accessed through the passage 21. A door 5 with a lock device 4 is installed at each entrance for entering and exiting the rooms 25 and 26 from the passage 21. Rooms 23 and 25 are adjacent and can be reached directly through the doorway. Rooms 24 and 26 are also adjacent and can be reached directly through the doorway. A door 5 with a lock device 4 is also installed at these doorways.

  In addition, when it is necessary to specify individually about the said door 5, as shown in FIG. For example, a door that opens and closes an entrance for entering and exiting the room 22 from the passage 20 is denoted as 5a, and a door that opens and closes the entrance and exit for traveling between the rooms 24 and 26 is denoted as 5g. For ease of explanation, it is assumed that the doors 5 shown in FIG. 4 are managed by different local controllers 2. That is, the local controller 2 is provided for each door 5. Moreover, the other door 5 does not exist in the area shown in FIG.

  In the vicinity of each door 5, a receiver 6 (not shown) with a built-in notification device 7 is installed.

  Each local controller 2 determines whether or not a fire has occurred (S201). If the fire detection device 17 has not detected the occurrence of a fire (No in S201), the local controller 2 performs normal control (S202).

  When detecting the occurrence of a fire, the fire detection device 17 transmits fire occurrence information to a specific local controller 2 (Yes in S201). In the local controller 2 that directly receives the fire occurrence information from the fire detection device 17, the information control means 10 distributes the fire occurrence information to the center device 1 and the other local controllers 2. Upon receiving the fire occurrence information, the center device 1 and each local controller 2 end the normal control and start predetermined evacuation control (S203).

  In the center apparatus 1, when the fire occurrence information is received, the device determination unit determines whether or not each connected device is operating normally (S204). For example, when the center device 1 receives predetermined failure information from the local controller 2, the device determination unit identifies a device that does not operate normally (that is, the door 5 that cannot be controlled) based on the received failure information. In addition, when there is a local controller 2 that cannot communicate with the center apparatus 1, the device determination unit identifies the door 5 managed by the local controller 2 as an uncontrollable door (device that does not operate normally). . When the device determination unit specifies a device that does not operate normally, the device determination unit transmits the specification result (abnormal information) to each local controller 2.

  If all the doors 5 are operating normally and there is no uncontrollable door 5, the center device 1 and each local controller 2 end the processing (No in S204).

  Even after the evacuation control is started, the receiver 6 receives the ID information from the IC tag 8 existing in the detection range 9. When receiving the ID information from the IC tag 8 (Yes in S205), the receiver 6 outputs the received ID information and its own device information to the local controller 2.

  In the local controller 2, after receiving the fire occurrence information, the determination unit 14 determines whether or not the IC tag 8 (person who carries it) is going to pass through the corresponding door 5 (traffic restriction place).

  Specifically, when the information control unit 10 receives the ID information from the receiver 6 after receiving the fire occurrence information, the determination unit 14 first has an IC tag 8 having the ID information on one side of the door 5. Or whether it exists on the other side of the door 5. For example, when the local controller 2 that manages the door 5a receives the ID information from the receiver 6, the determination unit 14 of the local controller 2 determines whether the IC tag 8 exists on the room 22 side of the door 5a. It is judged whether it exists in the channel | path 20 side rather than 5a.

  Such a determination can be easily realized by, for example, the receiver 6 including the antennas 6a and 6b. In the receiver 6 corresponding to the door 5a, the detection range 9 is set around the door 5a. The antenna 6a receives the ID information from the IC tag 8 existing in the room 22 side of the door 5a among the IC tags 8 existing in the detection range 9. The antenna 6b receives the ID information from the IC tag 8 present in the passage 20 side of the door 5a among the IC tags 8 present in the detection range 9.

  For the IC tag 8 for which the receiver 6 has received ID information for the first time within the predetermined time immediately before, the determination means 14 determines that it is going through the corresponding door 5. For example, when the antenna 6a receives the ID information, the determination unit 14 determines that the IC tag 8 is about to pass from the room 22 to the passage 20 side. Further, when the antenna 6b receives the ID information, the determination unit 14 determines that the IC tag 8 is about to pass from the passage 20 to the room 22 side.

  In addition, when the local controller 2 receives the abnormality information from the center device 1 (equipment determination unit), is the evacuation route continuing after the evacuation route determination unit passes through the door 5 (traffic restriction place) managed by the local controller 2 closed? It is determined whether or not (S206).

For example, let us consider a case where abnormality information indicating that the door 5g cannot be controlled is distributed from the center device 1.
In such a case, even if an evacuated person enters the room 24 from the passage 20, the refugee cannot proceed beyond that (room 26). That is, the refugee again passes through the door 5c and passes through the passage 20. I have to go back to For this reason, when the local controller 2 managing the door 5c receives abnormality information indicating that the door 5g cannot be controlled, the evacuation route determination means confirms that the evacuation route continuing from the room 24 side of the door 5c is closed. judge. In addition, when an evacuee passes the door 5c (traffic restriction place) from the room 24 and goes to the passage 20 side, the refugee can then pass through the doors 5a and 5b and go to another place. For this reason, the evacuation route determination means determines that the evacuation route continuing from the passage 20 side of the door 5c is not closed even if the abnormality information indicating that the door 5g cannot be controlled is received.

  The warning control means 16 of the local controller 2 gives a predetermined warning (guidance) based on the determination results of the determination means 14 and the evacuation route determination means. Specifically, the warning control means 16 determines that the IC tag 8 is about to pass through the corresponding door 5 (traffic restriction place) by the judgment means 14 and passes the door 5 (traffic restriction place). When the evacuation route determination unit determines that the subsequent evacuation route is closed (Yes in S206), the notification device 7 informs that the door 5 (traffic restriction place) is not passed. (S207).

  For example, when abnormality information indicating that the door 5g cannot be controlled is distributed from the center device 1, the local controller 2 that manages the door 5c, as described above, allows the evacuation route determination means to start from the room 24 side of the door 5c. It is determined that the subsequent evacuation route is closed. In such a case, in the local controller 2 that manages the door 5c, when the antenna 6b receives the ID information and the determination unit 14 determines that the IC tag 8 is about to pass from the passage 20 to the room 24 side. The warning control means 16 announces from the notification device 7 that the route after passing through the door 5c is closed.

  In the above example, it is assumed that the receiver 6 provided corresponding to the door 5c includes antennas 6a and 6b. The antenna 6a receives ID information from the IC tag 8 present on the room 24 side of the door 5c, and the antenna 6b receives ID information from the IC tag 8 present on the passage 20 side of the door 5c. And

  Further, in the local controller 2 that manages the door 5c, the same control is performed based on the determination result of the evacuation route determination means even when the evacuee approaches the door 5c from the opposite side (inside the room 24). Do.

  In the local controller 2, after the warning control means 16 starts the warning in S207, the warning is continued until the receiver 6 does not receive the ID information received in S205. When the ID information received in S205 is no longer received by the receiver 6, the warning control unit 16 stops the warning started in S207 (S209).

  Each local controller 2 may perform the control shown in FIG. 3 in parallel with the above control.

  In the entrance / exit management system having the above-described configuration, it is possible to appropriately guide the evacuated person in the event of a fire by using the receiver 6 installed in the vicinity of the door 5. For example, an evacuated person can know that the evacuation route after entering the room is closed before entering the room. For this reason, it is possible to significantly reduce the time required for evacuation.

  A person who is registered as a permitted person (for example, an employee or the like) moves freely in the building, and therefore often carries his own IC tag 8 in the building. For this reason, if the IC tag 8 is used, appropriate guidance can be given to people in the building even in the event of a fire.

  In the present embodiment, the case where the device determination unit is provided in the center device 1 has been described. However, this is just an example. The local controllers 2 in the system can transmit and receive information to and from each other via the communication line 3. For this reason, a predetermined local controller 2 (or each local controller 2) may be provided with a function of a device determination unit.

  The entrance / exit management system according to the present invention can be applied to a system that manages entrance / exit using an IC tag.
