First, the unlocking operation when the user does not have the key of the doorway 1 will be described with reference to FIGS. FIG. 7 is a diagram illustrating an example of an unlockable state of the lock apparatus according to the first embodiment. FIG. 8 is a diagram illustrating an example of an unlocked state of the lock device according to the first embodiment. In addition, FIG. 1 is a figure which shows an example of the locking state of the lock | rock apparatus concerning 1st Embodiment.

  For example, when an abnormality occurs in the monitoring area and the monitoring center receives the notification of the abnormality detection information, the monitoring center that is waiting is directed to the monitoring area. When a guard who does not have the key of the entrance door 1 installed in the monitoring area rushes and performs an unlocking operation to enter the monitoring area from the locked state shown in FIG. The user ID of the security guard is input to the installed operation unit 91. When the operation unit 91 receives the user ID, the control unit 80 performs user authentication by checking whether the received user ID is a user ID predetermined in the storage unit or the like, and uses the user ID. If the user authentication is successful and the solenoid 20 is not energized, the solenoid 20 is energized. As shown in FIG. 1, the locked state before the solenoid 20 is energized is that the leading end 12 of the deadlocking latch bolt 10 is inserted into the door 1 and the notch of the deadlocking latch bolt 10 is notched. The iron core 22 is fitted to the part 11a (see FIGS. 2 and 3), and the deadlocking latch bolt 10 is incapable of moving.

  When the solenoid 20 is energized by the controller 80, as shown in FIG. 7, the iron core 22 is inserted in the direction in which the iron core 22 of the solenoid 20 is inserted into the hole 21a (see FIG. 4) of the solenoid body 21, that is, in the β direction. When the lower end of the sloped cut portion 22a of the 22 moves to the position of the end portion of the cutout portion 11a of the deadlocking latch bolt 10, the fitting state between the iron core 22 and the cutout portion 11a of the deadlocking latch bolt 10 is released.

Since it is the same as this lock device, description is abbreviate | omitted.

  The security device 900 monitors (guards) the monitoring area where the doorway door 1 is installed, and the security mode is set to the security state. If an abnormality occurs in the monitoring area, the security device 900 is a report destination. It reports the abnormality detection information that an abnormality has been detected to the monitoring center. Further, the security device 900 is set to the security release state in the security mode, and does not report the abnormality detection information to the monitoring center when an abnormality occurs in the monitoring area. When the monitoring center receives the notification of the abnormality detection information from the security device in the monitoring area, the monitoring center gives an instruction to the waiting security guard to go to the monitoring area where the abnormality is detected, and if necessary, the police And report to related organizations such as fire departments. In the present embodiment, the lock device is connected to the security device by wire, but may be configured to be connected by wireless communication.

  Here, the security mode refers to the necessity of reporting to the monitoring center when various sensors installed in the monitoring area detect the opening of windows and doors or the presence of people, or notification to the monitoring area. This is a mode for determining the operation of the security device 900 during the detection operation of various sensors, such as whether or not it is necessary. The security mode includes a plurality of modes depending on necessity of notification, notification destination, necessity of notification to the monitoring area, and the like. As a typical security mode, when various sensors perform detection operations, for example, when monitoring area abnormalities are detected and a person entering a monitoring area is detected, a monitoring center that is a predetermined notification destination There is a security state in which the abnormality detection information is reported to the monitoring center and a security release state in which the abnormality detection information is not reported to the monitoring center when various sensors perform detection operations, and the security device 900 has a security mode operation unit 910 to be described later.
