  The room is usually a closed space isolated from the outside, but there is no problem if, for example, the upper part is not covered but practically impossible to enter from the outside. It is possible to use various kinds of firewood, moats and the like. In addition, the entrance / exit control may be performed not only by opening and closing doors installed on walls and walls, but also by moving the bridge up and down across the moat.

  For the storage unit, an internal storage device, an external storage device, and various electronic storage media used in a normal personal computer or the like can be used. The control unit may be an electronic circuit that performs a fixed logical operation, an electronic device that performs various logical operations by software, or the like.

  The control unit in the entry / exit control device of the present invention transmits the searched registered biometric information to a biometric information authentication device installed outside the room, and is specific to the user read by the biometric information authentication device. The biometric information and the registered biometric information transmitted are received from the biometric information authentication device, and the door installed in the room is locked and unlocked according to the collation result. .

  The door can be locked and unlocked by opening and fixing an electronic lock. As the biometric information authentication device, an electronic device that reads biometric information peculiar to a user, such as a fingerprint, a vein, an iris, and a voiceprint, and collates with registered biometric information is used.

  The storage unit in the entrance / exit control device of the present invention holds history information of the user's entrance / exit, and the centralized device responds to a request for collecting history information from a centralized management device installed outside the room. History information is transmitted to an entry / exit history storage unit inside the management apparatus, and the history information is erased after the history information is transmitted to the entry / exit history storage unit.

  The centralized management apparatus normally manages a plurality of rooms where entrance / exit management is performed, and periodically collects the history information of the entrance / exit of each room via the network, The history information regarding all the rooms held in the entrance / exit history storage unit inside the centralized management apparatus is updated. On the other hand, in each room, the entry / exit history information is temporarily transmitted to the central control device, and after the history information is deleted, the subsequent entry / exit history information is retained until the next history information collection request is made. For example, even if a failure occurs in the network at the time of the history information collection request, the entry / exit history information is held until the first history information collection request is made after the network is restored.

  An entrance / exit management system of the present invention is an entrance / exit management system that performs personal authentication of a user and manages entrance / exit of the user's room based on an authentication result, and is provided with an information registration control unit.

The registered biometric information is transmitted to the biometric information authentication device, and a result of collating the biometric information read by the biometric information authentication device with the registered biometric information is received from the biometric information authentication device. Accordingly, a control unit that transmits a signal for controlling the locking / unlocking unit is provided.

  The ID information registration device is similar to an entry card reader or an exit card reader, and reads a personal ID from a card carried by the user in advance. It may be considered that the biometric information registration device basically diverts only the function of reading the biometric information of the biometric authentication device. The information registration control unit does not need to have a function of holding the registration ID information and the registered biometric information. The information registration controller and the biometric information read by the ID information registration device and the biometric authentication device are used. In association with the one-to-one relationship, the function has a function of transmitting to the storage unit in the entrance / exit management device as registration ID information and registration biometric information, respectively. That is, the personal ID read from the card reader is compared with the registered ID information, and if there is a match, the registered biometric information associated with the personal ID one-to-one is searched.
