JPH06167145A - Security key safekeeping device and crime prevention system based on its application - Google Patents

Abstract

PURPOSE:To attempt a centralized control of locking and unlocking and crime prevention by installing communication ports to a signal processing section of a plurality of key housing boxes which lock and unlock with an electronic card and connecting a common signal line for free access to a center device. CONSTITUTION:Every time when a electronic card is read and scanned and a key is taken out or returned, information about these related operations is transmitted to a center device from an individual key safekeeping device K by way of a shared signal line. Then, the center device 30 concentratedly controls the key safekeeping devices K. If something trouble happens in one of the device K, the device 30 gives an alarm and troubleshoots the case promptly. If it is necessary, an outside printer is installed to the device 30, thereby printing out information for the operation records. Moreover, it is acceptable to install a crime prevention system which is connected to a signal line L, thereby detecting the opening and closing of a window and giving an alarm for troubleshooting. This construction makes it possible to build up a communication network in conformity with a desired scope and control extended key safekeeping devices with a single center device by connecting its network to the shared communication line.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 3 is a block configuration diagram showing an example of the hardware configuration of the security key storage device K according to the present invention. The CPU 11 constituting the signal processing unit is constituted by a card reader 2, a ten-key pad 3, an LCD (liquid crystal) and the like. In addition to the displayed display screen 4 and the key storage box 1, the abnormality alarm output means 12 and the like are connected. Further, the operating power from a general power line or the battery 13 is supplied through the power circuit 14. Further, the CPU 11 is provided with a communication port 25, and a common signal line L is provided here.
, A plurality of security key storage devices K ... Are connected to each other to form a network system as shown in FIG.
You can manage operation-related information and information that indicates the status of use.
In such a network system, operation-related information is read every time an operation is performed by reading and scanning an electronic card such as a magnetic card or an IC card from each key storage device K, or an operation such as taking out or returning a key. Since the data can be transmitted to the center device 30, one center device 30 can centrally manage a plurality of key storage devices K ...
When a trouble is discovered in the center device 30, an alarm can be generated in the center device 30 to promptly respond.

Since each key storage device K is not equipped with a printer, operation history information and the like cannot be easily printed out. However, when such management information needs to be printed out, the center device 30 side You can print with an external printer installed in. Further, in such a network, in addition to the operation history of each key storage device K, the central device 30 side can centrally manage management information such as prying open, unstored state of keys, and device abnormality occurrence.

A display screen 4 is provided on the front panel of the key storage device K, in which the operating status and abnormal information of the device are displayed.
It is designed to be displayed as text information. The abnormal alarm output means 12 is composed of an abnormal buzzer, an abnormal lamp, etc., and if necessary, the display screen 4
It is designed to be operated in parallel with the text information in.

Further, on the front panel 18 of the key storage device K, as shown in FIG. 5, a card reader 2 having a reading slit 2a, a ten-key pad 3, a display screen 4, and a key storage box 1 are provided.
