CONTROL SYSTEM FOR ENTRANCE INTO/EXIT FROM ROOM

PROBLEM TO BE SOLVED: To provide a control system for entrance into/exit from a room, which has an enhanced maintainability. SOLUTION: This control system 10 for entrance into/exit from the room comprises an electric lock control unit 30 which controls the operation of an electric lock 22 by switching between contacts of a contact circuit relay 35 on the basis of the result of authentication from an IC card reader 23, and a central control unit 40 which is communicably connected to the control unit 30. The plurality of sets of IC card readers 23 and electric locks 22 are connected to the control unit 30. The control unit 30, which is equipped with a plurality of relay unit modules 31 unitized for each contact circuit relay 35 corresponding to each electric lock 22, estimates the deteriorated state of each contact circuit relay 35 on the basis of the number of times of switching of the contact circuit relay 35 for each relay unit module 31, and displays the deteriorated state on a display portion 37. Additionally, the central control unit also displays the deteriorated state of the contact circuit relay 35 for each relay unit module 31. COPYRIGHT: (C)2008,JPO&INPIT
