Anti-error lock remote permission device for power substation

Abstract

The invention relates to an anti-error lock remote permission device for a power substation. The device comprises locks in the power substation and a computer key for unlocking the locks, wherein the locks are attached by corresponding radio frequency identification electronic tags which are provided with independent lock codes respectively; the computer key comprises a battery, an automatic route management (ARM) processor which is used for identifying, comparing and controlling input signals, a card reading module, a real-time clock module, a liquid crystal display (LCD) module, an information storage module, a communication module and a locking driving module; the card reading module communicates with the radio frequency identification electronic tags through a radio frequency antenna; the communication module which is connected to the communication port of the ARM processor is connected with an upper computer; and the LCD module, the information storage module, the real-time lock module and the locking driving module are connected with the input and output ports of the ARM respectively. The anti-error lock remote permission device for the power substation has a rational structure and is convenient to operate, and safety and reliability can be improved.

Description

technical field [0001] 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 [0002] 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. [0003] In order to avoid these accidents more reliably, the anti-misoperation locking method of "measurement and control interlock + electrical interlock" is currently adopted. However, effective anti-misoperation locking technical means have not yet been adopted for the operating handles of various mechanism boxes, terminal box doors and manual operation equipment in the substation. [0004] Although the five-proof m...

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
