Coal mine power supply monitoring system and method applicable to various protocol comprehensive protectors

Abstract

The invention discloses a coal mine power supply monitoring system and method applicable to various protocol comprehensive protectors. The system comprises a field bus network formed by a power monitoring station, a signal isolator and a comprehensive protector and an industrial Ethernet formed by an upper computer, ground network switches, underground network switches and the power monitoring station. According to the invention, configuration software of the upper computer reads and writes register data of programmable serial controllers forming the power monitoring station, displays the data in real time and issues an instruction, embedded software of the programmable serial controllers controls serial ports thereof to send an inspection and action instruction, data sent by the comprehensive protector is received and stored, and the comprehensive protector collects states and data of a switch and controls the switch to operate. The system and method disclosed by the invention overcome a defect that a coal mine power supply monitoring system at present can only monitor a specific protocol comprehensive protector and is in universality, realize grouped multichannel parallel communication with various different communication protocol comprehensive protectors in batches, and solve an access problem of different specifications of comprehensive protectors provided by different manufacturers in the construction process of the coal mine power supply monitoring system.

Description

technical field [0001] The present invention relates to a coal mine power supply monitoring system, more specifically, relates to a coal mine power supply monitoring system for underground coal mines, which can implement online monitoring of coal mine underground power supply and distribution equipment, and is especially applicable to multiple protocol comprehensive protectors . Background technique [0002] The degree of mechanization and automation of coal mines is constantly improving. With the increase of production and the expansion of the working surface, the distance of underground power supply, the number of substations, the number and types of loads are all increasing, which affects the stability of the coal mine power supply and distribution system. , security and continuity put forward higher requirements. The failure of power supply equipment in coal mines affects the production of coal mines and the safety of personnel, so the reliability of power supply and di...

AI Technical Summary

Problems solved by technology

[0003] The coal mine construction period is long and the service life is long. In the coal mine power supply system, it is inevitable to use high and low voltage power distribution equipment of different manufacturers, different periods, and different specifications. There are many types of comprehensive protectors used in these power distribution equipment. Although Most of the integrated protectors have remote communication functions, but the communication protocols are different, which brings difficulties to the construction of coal mine power supply monitoring system

[0004] The existing coal mine power supply monitoring system can only monitor a specific protocol comprehensive protector, which has poor versatility and has high requirements for the consistency of coal mine power supply equipment. If new power supply equipment is added in the future, it needs to use the same communication protocol to connect to the system.
