Abstract

PROBLEM TO BE SOLVED: To provide a sure lock control system at a low cost by incorporating a sensor and a communication equipment into a lock and receiving lock information by means of a control device disposed at another location. SOLUTION: A lock checking sensor 9 and a radio control communication equipment 10 are mounted to all locks. And a lock for reporting use receives judgment demand signals outputted from a lock having control function to examine conditions of the sensor 9. Nothing is done if locking is completed. In the case of a poor locking, a bad judgment signal is outputted from a transmitter to report it to a lock having control function. The judgment signal is outputted only at the time during which judgment requirement outputted from the lock having control function is being received. And the lock for reporting use receives the judgment demand and sends back a poor lock signal, following which an alarm is displayed, so that the occurrence of poor lock in a building can be checked. Consequently, judgment can be made at a final stage of locking action in the building and hence poor locking can be checked without omission.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock management system for centrally remotely checking the locking status of a building.

[Prior art and its problems] In order to check the locking status of a building, a lock is individually visually inspected, or a check sensor is attached to each lock, and the lock is placed in a building. Lock control is performed collectively by connecting the control device and the sensor with a signal line and confirming a signal. In the above-mentioned conventional system, when the inspection is performed individually, the more the number of the locked locations, the more easily the omission of the inspection occurs, and the cable connection type locking management system has a disadvantage that the system becomes large and the cost is high.

[Object of the Invention] The present invention eliminates the above-mentioned problems,
An object is to provide an inexpensive and reliable lock management system.

[Summary of the Invention] In order to achieve this object, in the present invention, a sensor for determining the locking status and a communication function for notifying the locking status to the outside are incorporated in all locks.
A signal transmitted from these locks is received by a lock with a management function and displayed as an alarm, thereby enabling lock management without wiring.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. FIG. 1 is a structural view of the lock for exclusive use of a report, which comprises a key catching unit 1, a lock confirmation sensor 2, and a radio control communication device 3. FIG. 2 is a detailed configuration diagram of the radio-controlled communication device 3, which includes a sensor control unit 4, a receiver 5, a transmitter 6, and a storage battery 7. FIG. 3 is a structural view of a lock having a management function installed in at least one place, and is composed of a key portion 8, a lock confirmation sensor 9, and a radio control communication device 10. FIG. 4 is a detailed configuration diagram of the radio-controlled communication device 10, and includes a sensor control unit 11, a receiver 12, a transmitter 13,
It comprises an alarm output circuit 14, an alarm sound source 15, and a storage battery 16. The difference between the radio control communicators in FIGS. 2 and 4 is that an alarm output circuit 14 and an alarm sound source 15 are additionally provided in FIG. FIG. 5 is a flowchart of the operation of the lock for exclusive use of the report. The operation will be described with reference to FIG. Step 5 to 1
When the judgment request signal output from the lock with the management function is received in step 5, the status of the lock confirmation sensor is checked in steps 5-2. If the lock is completed, nothing is performed. If the lock is defective, a defect determination signal is output from the transmitter in steps 5 and 3 to notify the lock with the management function. The output of the determination signal is output only while the determination request output from the lock with the management function is being received. FIG. 6 is a flowchart showing the operation of the lock with the management function.
The signal corresponding to the judgment request signal of ~ 1 is the output of the judgment request signal of steps 6-2. This output is output only during the locking in the preprocessing steps 6-1. However, the term “locking” as used herein generally refers to a state in which the window in the building is locked and then the final entrance is locked. Means Now, when the judgment request signal is transmitted in steps 6 and 2, this signal is received by the lock only for reporting, and a lock failure signal is returned. As a result, an alarm is displayed in steps 6 to 4, and it can be confirmed that a locking failure has occurred in any of the buildings. In this embodiment, it is not possible to determine where the occurrence of the lock failure occurs, but it is necessary to provide a function for displaying the lock failure on each lock, or to output a lock identification signal in addition to the lock failure signal described above. If the information is displayed on the lock with the management function, it is easy to determine the defective locking position.

[Effect of the Invention] As described above, according to the centralized management locking management system of the present invention, it is possible to judge a locking failure at the final stage of the locking operation in the building, so that the entire building is easily locked. Can be prevented.
