Embodiment 1

[0043] see figure 1 , embodiment one of the method provided by the present invention, specifically includes:

[0044] Step 1. Read the ID of the ground wire identification unit, the code information of the ground wire, and the state information of the ground wire from the ground wire identification unit in which the ground wire state information has been written;

[0045] The grounding line identification unit is in one-to-one correspondence with the grounding lines, and is used to store grounding line information. The grounding wire identification unit ID is the number used to identify the grounding wire identification unit, and the grounding wire code is the number used to identify the grounding wire. The combination of the two ensures the uniqueness of the grounding wire. When the grounding line identification unit is in the initialization state, only the grounding line identification unit ID and the corresponding grounding line coding information are stored therein. Ther...

Abstract

The invention discloses a ground wire status monitoring and management method, which comprises the steps of: reading ground wire identification unit identity (ID), ground wire coding information and ground wire status information in a ground wire identification unit in which the ground wire status information is written; and transmitting the information to a ground wire management unit through a general packet radio service (GPRS) wireless communication network to enable the ground wire management unit to receive and store the information, determine a corresponding ground wire according to the ground wire identification unit ID and the ground wire coding information and conduct logic operation according to the status information of the ground wire and the connection relationship of a line to generate interlocking information which is transmitted to an anti-misoperation interlocking system. The invention additionally discloses a ground wire status monitoring and management device and a ground wire status monitoring and management system.

Description

technical field [0001] The invention relates to the field of power system monitoring and management, in particular to a method, device and system for monitoring and managing the state of ground wires. Background technique [0002] In the power system, unplanned or abnormal outages of power supply equipment are often caused by human errors, causing heavy losses to people's lives and property. In order to ensure the safe operation of the power grid, the current common method is to use a five-proof locking device. When an operation on high-voltage switchgear or components will cause an electrical accident, the device will use computer technology to take measures to prohibit the operation. , in order to prevent the occurrence of operational accidents. The five-proof locking device has five-proof functions: 1. Prevent mis-disconnection and mis-closing of the circuit breaker 2. Prevent the isolation switch from being pulled and closed with load 3. Prevent the live wire from being...
