Mine monitoring system

Abstract

The invention relates to the technical field of monitoring, and discloses a mine monitoring system. The mine monitoring system comprises an underground monitoring module, a ground centralized controlmodule, an underground mutual access module and a ground and underground interconnection module, wherein the underground monitoring module comprises an information acquisition unit, a display interface unit, a communication interface unit and an alarm unit; the ground centralized control module is used for executing a remote setting function, remotely setting action parameters of a protection device and switching protection equipment when a dispatcher permits; and the underground mutual access module is used for communication between underground communication modules. According to the mine monitoring system, real-time on-line monitoring of an underground substation is realized, and a fault point can be quickly positioned when a fault occurs, so that a worker can effectively eliminate a fault and shorten a power failure and transmission period, and the mine monitoring system is of great significance in safe and stable operation of an underground coal mine power supply system.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to a mine monitoring system. Background technique [0002] Modern coal mine production is inseparable from the support of electrical equipment and electric energy. The power supply system maintains underground mining, transportation [0003] The normal operation of safe production activities such as transmission, ventilation, drainage, lighting, etc. At present, the common voltage levels in major coal mining enterprises in my country are 10KV, 6KV, 3.3KV, 1.14KV, 0.66KV, etc. The underground power supply system of coal mines is mainly composed of power distribution devices , mobile substation, switchgear and other electrical equipment. The stable and reliable operation of the entire power supply system is closely related to the production efficiency and safety of coal mines. In coal mines, in order to ensure the reliable operation of the power supply line and the safety of perso...

AI Technical Summary

Problems solved by technology

In coal mines, in order to ensure the reliable operation of the power supply line and the safety of personnel, the power supply equipment will be equipped with protection devices such as leakage protection and short circuit protection. When the line has overvoltage, overcurrent, short circuit and other faults, the protection equipment will automatically open and close The circuit breaker cuts off the faulty line, causing a power failure, which brings hidden dangers to safe production. Therefore, most underground substations have special personnel to inspect the status of the protection device

However, with the deepening of mining and the increase of power distribution points, simple personnel inspections are not only a waste of manpower, but also due to the complex working environment underground, difficult troubleshooting, and long periods of power outage and transmission, affect the work efficiency of coal mining areas

In addition, if there is no real-time monitoring system, it is difficult to grasp the actual operation status of each substation, and the location and cause of the accident are not clear
