In the first embodiment, a case where a user who owns the IC card 13 as the recording medium enters the room 10 will be described.

  First, in step S101 of FIG. 3, it is determined whether or not the IC card 13 has been read by the card reader 23 for room entry. Here, when there is no user entering the room and the IC card 13 is not read and the read information is not input from the room card reader 23, the determination of No is repeated in step S101. At this time, if a reading error occurs such as the expiration date of the IC card 13 is expired, it is similarly determined No in step S101.

  In such a state, when the user causes the card reader 23 to read the IC card 13 (Yes in S101), information acquisition processing is performed in step S103, and the predetermined information recorded on the IC card 13 is Obtained as read information. Next, in step S105, it is determined whether or not the permitter information is included in the read information acquired in step S103. If the permitter information is not included in the read information, it is determined No. . Then, a locking process is performed in step S117, controlled by the control device 25, the electric lock 21 is locked, and the door 11 is not allowed to enter the room.

  On the other hand, if permitter information is included in the read information (Yes in S105), it is determined in step S107 whether the permitter information includes the second permission level. Here, when the second permission level is included in the permitter information (Yes in S107), it is determined that the manager Pm has entered the room, and the room is entered in step S113 without detecting the room entry state described later. History update processing is performed. The entry history is a reading history in which the current occupants and their permission levels are stored in the memory 27. When the administrator Pm enters the room as described above, the entry of the administrator Pm with respect to the entry history. Information about is reflected. Then, unlocking processing is performed in step S115, and the electric lock 21 is unlocked and controlled by the control device 25, and the door 11 is allowed to enter the room.

  That is, as illustrated in FIG. 4A, when the manager Pm enters the room 10, entry is permitted regardless of the room 10 entry state.

  On the other hand, when the second permission level is not included in the permitter information and the first permission level is included in the permitter information in the step S107, it is determined as No for the worker Pe entering the room. . Next, in step S109, a room entry state detection process is performed. In this process, based on the room entry history stored in the memory 27, the current person entering the room and its permission level are detected. Subsequently, in step S111, it is determined whether or not the manager Pm is entering the room, and if it is determined from the entry history that the manager Pm is entering the room (Yes in S111), the above-described step S113 and subsequent steps. This process is performed, and the door 11 enters the room ready state.

  That is, as illustrated in FIG. 4B, when the worker Pe enters the room 10, entry is permitted only when the manager Pm enters the room 10.

  If it is determined in step S111 that the manager Pm is not entering the room from the room entry history (No in S111), a locking process is performed in step S117, and the door 11 is not allowed to enter the room.

  That is, as illustrated in FIG. 4C, when the worker Pe enters the room 10, if the manager Pm does not enter the room 10, the entry is not permitted.

  Next, the locking / unlocking process at the time of leaving the room by the CPU 26 in the first embodiment will be described with reference to FIGS. FIG. 5 is a flowchart illustrating the flow of the locking / unlocking process when the CPU 26 leaves the room according to the first embodiment. FIG. 6 is an explanatory diagram for explaining the locked / unlocked state when leaving the room, FIG. 6 (A) shows the state when the worker Pe leaves the room, and FIG. 6 (B) shows another manager Pm. 'Shows the state when the manager Pm leaves the room where the room is entered, and FIG. 6C shows the state when the manager Pm leaves the room where no other manager is entering.

  First, in step S201 of FIG. 5, it is determined whether or not the IC card 13 has been read by the leaving card reader 24. If no IC card 13 is read and no reading information is input from the leaving card reader 24 because there is no user leaving the room, the determination of No is repeated in step S201.

  In this state, when the user causes the exit card reader 24 to read the IC card 13 (Yes in S201), information acquisition processing is performed in step S203, and the predetermined information recorded in the IC card 13 is Obtained as read information. Next, in step S205, it is determined whether or not the permitter information is included in the read information acquired in step S203. If the permitter information is not included in the read information, it is determined No. . Then, in step S219, a locking process is performed, and the door 11 enters a room unacceptable state.

  On the other hand, if permitter information is included in the read information (Yes in S205), it is determined in step S207 whether the permitter information includes a second permission level. If the second permission level is not included in the permitter information (No in S207), it is determined that the worker Pe has left the room, and the entry history is updated in step S215 without detecting the entry state. Processing is performed, and information related to leaving of the worker Pe is reflected in the entry history. Then, unlocking processing is performed in step S217, and the electric lock 21 is unlocked and controlled by the control device 25, and the door 11 is allowed to leave.

  That is, as illustrated in FIG. 6A, when the worker Pe leaves the room 10, leaving the room 10 is permitted regardless of the entering state of the room 10.

  On the other hand, when the second permission level is included in the permitter information in step S207, it is determined that the manager Pm has left the room and the determination is Yes. Next, in step S209, a room entry state detection process is performed, and based on the room entry history stored in the memory 27, the current person entering the room and its permission level are detected. Subsequently, in step S211, it is determined whether or not another manager is entering the room, and when it is determined from the room entry history that another manager Pm ′ is entering the room (Yes in S211), The process after step S215 is made, and the door 11 is ready to leave.

  That is, as illustrated in FIG. 6B, when the manager Pm leaves the room 10, the exit is permitted only when another manager Pm ′ enters the room 10. It becomes.

  If it is determined in step S211 that no other manager is entering the room from the entry history (No in S211), it is determined in step S213 whether the worker Pe is entering the room. Here, when it is determined that the worker Pe is entering the room (Yes in S213), the locking process is performed in Step S219. In this process, the electric lock 21 is locked by the control device 25, and the door 11 is not allowed to leave.

  That is, as illustrated in FIG. 6C, when the manager Pm leaves the room 10, when only the worker Pe enters the room 10, the exit is not permitted.

  If it is determined in step S213 that the worker Pe is not in the room (No in S213), the manager Pm is the last person leaving the room, so that the processing after step S215 described above is performed. The door 11 is ready to leave.

  As described above, in the entrance / exit management system 20 according to the first embodiment, the permitter information recorded on the IC card 13 has a first permission level and a security level higher than the first permission level. Either one of the higher second permission levels is included. When the permitting person information of the first permission level is read by the card reader 23 for entering the room, the person (manager Pm) having the second permission level is detected according to the entry history stored in the memory 27. In this case, the electric lock 21 is unlocked by the control device 25.

As a result, if the manager Pe enters the room, the worker Pe is allowed to enter the room 10 because the electric lock 21 is unlocked in accordance with the reading of the authorized person information of the IC card 13 possessed. Therefore, it is possible to reduce the load on the administrator Pm related to security. Further, the worker Pe can ensure security because the electric lock 21 is not unlocked unless the manager Pm enters the room.
Therefore, security and convenience in the entrance / exit management system 20 can be improved.

  Further, in the entrance / exit management system 20 according to the first embodiment, when the permitter information of the second permission level is read by the card reader 23 for entrance, the controller 25 does not consider the entrance history. The electric lock 21 is unlocked. Thereby, if it is manager Pm, since a permission level of a room occupant is not detected according to the above-mentioned room entry history at the time of room entry, the room can be entered smoothly.

  Furthermore, in the entrance / exit management system 20 according to the first embodiment, when the permitter information of the second permission level is read by the exit card reader 24, another manager Pm ′ is detected from the entrance history. In this case, the electric lock 21 is unlocked by the control device 25. As a result, when another manager Pm ′ enters the room, the manager Pm is in an unlocked state and is allowed to leave, so that only the worker Pe enters the room. Without it, security can be improved.

  Further, in the entrance / exit management system 20 according to the first embodiment, when the permitter information of the first permission level is read by the exit card reader 24, the controller 25 does not consider the entrance history. The electric lock 21 is unlocked. Thereby, if it is worker Pe, since it will not detect a permission level of a room occupant according to the said room entry log | history at the time of evacuation, it can evacuate smoothly.

  Furthermore, in the entrance / exit management system 20 according to the first embodiment, when the permitter information of the second permission level is read by the exit card reader 24, only the worker Pe is detected from the entrance history. In addition, the electric lock 21 is locked by the control device 25. As a result, when the manager Pm leaves the room 10, when only the worker Pe enters the room, the electric lock 21 is locked and the leaving of the room is not permitted. Security can be improved by eliminating the state of entering the room.
