Intelligent key cabinet

Abstract

The invention relates to article management and provides an intelligent key cabinet which saves manpower resources, carries out precise management on keys of locks special for electric meter boxes, is safe and reliable, achieves intelligent management, achieves self-service borrowing and lending and completely eradicates hidden danger of electricity stealing and leakage. The intelligent key cabinet comprises a cabinet body, and further comprises an industrial control host computer, an identity recognition device, a control panel, a display screen, multiple indicator light sets, multiple RFID labels, multiple electric control locks, multiple displacement sensors, multiple RFID antenna panels and an RFID reader. The RFID antenna panels communicated with the RFID labels are arranged on drawers of all layers respectively, one indicator light set is arranged on each drawer of all layers, the displacement sensors and the electric control locks are also arranged on the drawers of all layers, the industrial control host computer reads the storage, taking and using information of keys in the drawers of all layers in real time through the RFID reader and all the RFID antenna panels, and the industrial control host computer senses the opening states of the drawers of all layers through the displacement sensors and controls the opening/closing of the drawers of all layers through the electric control locks.

Description

technical field [0001] The invention relates to item management, in particular to an intelligent key cabinet. Background technique [0002] The large-scale transformation of rural power grids has basically come to an end. In the past, the backward model of meter reading "take a bunch of keys and find a household for a long time" has been replaced by a special lock for the meter box with special functions. The common special-purpose lock key management method of the electric meter box of existing power supply is as follows: 1, loose type management so-called " loose type " management, promptly every agricultural electrician has key. 2. Centralized management: the keys are placed in the tool cabinet uniformly, and the day-to-day staff is responsible for issuing them. As a result, there are problems in the management of the special lock keys for the meter box: 1) The first type of key is not managed centrally, and the whereabouts of the key is unknown; 2) If it is managed cen...

Problems solved by technology

As a result, there are problems in the management of the special lock keys for the meter box: 1) The first type of key is not managed centrally, and the whereabouts of the key is unknown; 2) If it is managed centrally, the management of borrowing and returning the key is manually registered, and the following problems are very likely to occur. Missing without reason; When and who picked up the keys; Unable to confirm which key was taken; Keys not returned without being noticed; Keys misplaced and difficult to find; 3) The keys of some locks were not handed in after the administrator of the station area left, resulting in no keys when needed, and, for the resigned administrator, there is a high risk of electricity theft Temptation; 4) Many metering boxes do not have locks or the locks are broken, users can easily open the metering boxes by themselves, and the safety of the meter cannot be guaranteed; 5) Materials such as meter reading machines and lead sealing pliers are not intelligently managed

[0003] In short, the existing special lock key management loopholes in the meter box are very large, and it is impossible to ensure the safety of electricity use in the meter box. It is very easy to be used by users with ulterior motives to steal electricity, and there is no strong restraint mechanism for internal employees to obtain keys. , there is a high hidden danger of electricity leakage in the meter box

China Patent No. 200910184688.2 discloses a smart key management box: the smart key management box can effectively manage and control the use and recording of various keys related to the safety of substations, and realize intelligent management. The smart key management box of this invention , it includes a reading unit, a management control unit and an execution unit, and the reading unit and the execution unit are respectively connected to the management control unit through a transmission line, but this invention cannot carry out an inventory of the keys in the management box in real time, and cannot be specific to the key Each key is numbered, and it is impossible to check whether the key has been lent or returned, and it is still impossible to eliminate the hidden danger of electricity theft and leakage
