Intelligent remote control locking method and apparatus for preventing electric misoperation

Abstract

The invention provides one intelligent remote close method and device to avoid electrical error operation, which comprises PAD computer, blue teeth opener and intelligent lock ware, wherein, the PAD computer is imbedded with relative operation software and blue teeth module for communication by blue teeth opener to collect relative information; it judges and sends operation order according to the rules to drive blue teeth opener; the intelligent lock ware has automatic opening and feedback information for display and relative operations by persons.

Description

technical field [0001] The invention belongs to the field of technical measures for preventing electrical misoperation of an electrical system, and in particular relates to an intelligent remote control locking method and a device thereof for preventing electrical misoperation. Background technique [0002] In the power system, in order to prevent electrical misoperation accidents, collectively referred to as "five preventions": prevent mis-opening and closing of circuit breakers; prevent load opening and closing of isolating switches; line (earth switch) and circuit breaker (isolation switch); to prevent accidental entry into the charged interval, the general structure of the developed microcomputer anti-misoperation locking device consists of the following four parts: [0003] [0004] Through the operation on the intelligent analog disk, the operation command is sent to the industrial computer, and the operation ticket is issued. At the same time, through the serial co...

AI Technical Summary

Problems solved by technology

[0006] 1. There are many structural links, the auxiliary operation time is long, the operation speed is slow, and the power outage maintenance time of the substation is long

[0007] 2. The computer key can only check and unlock the lock according to the given sequence. It cannot judge whether there is high-voltage electricity on the operation route or in the interval. The "five prevention" functions cannot be fully realized, so there are still hidden dangers of accidents

[0008] 3. Most of the locks used are coded padlocks, which are not fixedly installed and forced to lock. There may be a phenomenon of "empty travel" (that is, after the locking device is opened, the actual operation is not performed, that is, the unlocking and operation of the next operation content is transferred), resulting in mishandling accident

[0009] 4. The cost is too high. It is suitable for substations above 110KV and large power plants. There are a large number of substations below 35KV. If a large number of configurations will inevitably cause great waste

[0020] On September 20th, 2006, the Chinese patent with the publication number CN1835145A discloses a hand-held microcomputer anti-misoperation locking system, which still adopts the computer key of the pincer grip type unlocking mechanism, but adds a new PDA component, which can neither collect the state of the lock and Unlocking condition information, and remote automatic closed-loop control of on-site locks, only conventional simulation preview and generation, modification, output, and display of operation tickets, and no communication function with computer keys and locks. The lock structure is still mechanical. The coded lock can only guarantee the unlocking sequence according to the work ticket generated by the handheld computer. It does not have the functions of judging the unlocking conditions, detecting the operation in place information, and automatically locking after operation. The utilization of the handheld computer stays at a very low level. There is no essential improvement and improvement in the "five defenses", and the operator cannot actively follow the "five defenses" rules to guide the operator to operate
