In the entrance / exit management system, for example, a card reader installed outside the entrance door of the room is connected to a signal line from a local control panel installed on each floor of the building, and an electric lock provided on the door is connected.

The local control panel is connected to a center device installed in a security room or the like or a client device installed in a management department such as the general affairs department via a local area network (hereinafter referred to as "LAN"). The center device displays management information such as a map of the building where the entry / exit management system is installed. The client device performs various settings and processes such as registration and deletion of user identification information on the entry / exit management control panel, history search, and occupancy status.

Enrolled employees such as employees who enter and leave facilities and rooms carry, for example, an IC card in which user identification information is registered. By holding the IC card over a card reader, the user identification information is read and sent to the local control panel. , The electric lock is unlocked and the door can be opened to enter and exit when the matching with the user identification information registered in advance on the local control panel is obtained.

In addition, the user identification information obtained by collation on the local control panel is sent to the center device together with the time information, and the entry time is recorded in the entry / exit information managed by the center device and managed as a resident. ..

By the way, when an office building or factory is evacuated due to a disaster such as a fire or an earthquake, the safety manager confirms the evacuees' roll calls to confirm their safety, but it is difficult to confirm their safety accurately. Since it takes time to confirm the roll call, a disaster safety confirmation system using an entry / exit management system has been proposed.

This disaster safety confirmation system uses an entry / exit management system (access control system) to manage entry / exit and entry / exit in normal times, and creates and manages the location data of full-time employees who are in the facility. On the other hand, in the event of a disaster, a list of the names of the persons subject to safety confirmation is created from the location data in the facility and transmitted to the safety confirmation server, and the names of the persons subject to safety confirmation read from the safety confirmation server to the safety confirmation terminal. A list is displayed, and a roll call is performed in this state, and the roll call result is transmitted from the safety confirmation terminal to the safety confirmation server.

As a result, the information of the person who is present at the time of starting the disaster evacuation is provided to the safety manager, and the safety manager can confirm the safety of the subordinates based on the information.

Japanese Patent No. 4335756
