Permission device for error prevention locks of substation

Abstract

The invention relates to a permission device for error prevention locks of a substation. The permission device comprises locks in the substation and computer keys which are used for unlocking the locks, wherein corresponding radio frequency identification electronic labels which have respective own lock codes are adhered to the locks; each of the computer keys comprises a battery, an ARM processor which is used for identifying, comparing and controlling the input signals, a card reading module, a real-time clock module, an LCD display module, an information storage module, a communication module and a locking driving module; the card reading modules communicate with the radio frequency identification electronic labels through radio frequency antennas; the communication modules which are connected with communication ports of the ARM processors are connected with an upper computer; and the LCD display modules, the information storage modules, the real-time clock modules and the locking driving modules are respectively connected with input / output ports of the ARM processors. The permission device for the error prevention locks of the substation is reasonable in structure and convenient to operate, and is capable of improving the safe reliability.

Description

[0001] This application is a divisional application of the invention patent application with the application number: 201210068203.5, the invention name is "Remote Licensing Device for Substation Misoperation Prevention Lockset", and the application date is: March 15, 2012. technical field [0002] The invention relates to a remote permitting device for an anti-misoperation lockset of a substation, and belongs to the technical field of five-proof microcomputer locks for a substation. Background technique [0003] With the rapid development of the power grid, a large number of equipment in the substation has increased. Although the operation and maintenance personnel can identify various equipment by marking double names, it still happens from time to time to enter the charged interval by mistake and misoperate the grid equipment. [0004] In order to avoid these accidents more reliably, the anti-misoperation locking method of "measurement and control interlock + electrical int...

AI Technical Summary

Problems solved by technology

When the number of devices in a substation exceeds 1024, the codes of the locks will be repeated, which will bring great safety hazards to the operation safety; 2. Only one substation can be controlled

Since only one substation can be controlled, different devices in different substations produce the same code

If maintenance personnel want to perform batch work such as patrolling and eliminating defects in multiple substations in sequence, the operating personnel must always follow the maintenance personnel and perform computer key authorization on site, which greatly wastes the time and energy of the operating personnel
