<p><P>PROBLEM TO BE SOLVED: To provide a control device which controls a door to allow a person to come in and out to use a grace period being a fixed period for performing any processing such as automatic locking of the door while the door remains closed after the fixed period and starting to inform while the door remains open after the fixed period after the fixed period by conforming to actual situation of use and situation of operation without deciding the grace period depending on the experience of a manager of a coming-in-and-out management system. <P>SOLUTION: In this control device, the time when an event occurs is extracted from log, and the grace period is updated based on the difference in time between the door opening time when a user opens the door actually and the time when the event occurs. For example, the grace period until the door is automatically locked while the door remains closed is updated based on the difference in time between the unlocking time and the door opening time. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
