Abstract

The invention discloses a mine power network monitoring and guaranteeing system. The mine power network monitoring and guaranteeing system comprises a comprehensive control center, an optic fiber Ethernet exchanger, a KFJ81 underground measurement and control station, a detection and alarm unit, an electric energy information collection unit, an intelligent protection unit and a power source unit, wherein the detection and alarm unit, the electric energy information collection unit and the intelligent protection unit are communicated with the KFJ81 underground measurement and control station through an RS-485 communication mode, and mainly perform state detection, fault early warning, information collection and remote control on a mine power network, the KFJ81 underground measurement and control station exchanges information with the comprehensive control center through two methods of using the optic fiber Ethernet exchanger and a ZigBee wireless network, and the power source unit is composed of a common power source and an emergency power source, and guarantees that the mine power network monitoring and guaranteeing system can run smoothly under various situations. The mine power network monitoring and guaranteeing system achieves the purposes of monitoring and controlling the mine power network from all directions, improves running efficiency and safety level of the mine power network, and provides reliable guarantees for safe production of a mine.

Description

technical field [0001] The invention relates to the field of monitoring systems, in particular to a mine grid monitoring and guarantee system. Background technique [0002] The monitoring system is a comprehensive automation technology product that integrates a series of technologies such as computer engineering technology, information collection technology, communication technology and intelligent control technology. Now it has been widely used as a safety prevention technology facility in social life and production. Practice. [0003] At present, there are often phenomena such as no-fault false tripping, unstable line operation status, and untimely power transmission after faults in the mine power grid, which has brought great troubles to the safe power supply and normal production of the coal mining industry. Due to the complexity and particularity of the mine power grid, how to effectively monitor it and take appropriate measures to ensure the safe, stable and efficient...
