Coal mine power monitoring system

Adopt MW-Ring ring topological structure, each substation in the underground through the MIGE7110 low-power embedded industrial Ethernet module Gigabit optical port and the host group of the monitoring center to build a Gigabit redundant ring network. Each power substation uses the industrial Ethernet switch module MIEN3105 to access the high and low voltage sites nearby, and passes the information collected by the front end to the monitoring center through the redundant ring network. The bottom equipment is connected to the MIEN3105 product in the substation through RS-485 or CAN bus to complete the protection box measurement of the power equipment. The application of power monitoring system using MW-Ring ring network technology improves the rational comprehensive wiring capacity of the mine, ensures the efficiency of statistical analysis of electricity consumption and electricity consumption, and solves the problem of timely reporting of high- and low-voltage power grid leakage detection data in mines Many difficulties such as real-time monitoring of power grids and fault warnings have laid a solid foundation for the construction of intrinsically safe mines.?
