Design and application of intelligent monitoring system for main drainage in coal mine based on Plc
The underground pump is one of the main equipments in coal mine safety production,the realization of remote control and monitoring of the underground main drainage pump house is an important part of the intelligent construction of coal mine.At pres-ent,there are a series of problems in the main drainage monitoring system of coal mine pump house,such as low degree of automa-tion,intelligence and information,high labor intensity of manual operation,high rate of equipment failure and difficulty of system fail-ure checking,etc.,it seriously affects the production efficiency and economic benefit of coal mine.For this reason,the author de-signed a multi-layer network control structure of mine main drainage system based on Siemens 300 Series PLC and the combination of upper computer and lower computer,an intelligent monitoring and control system for drainage,which integrates information collec-tion,data processing,network communication and integrated control,is developed,according to the principle of"Shifting peak and filling valley",the labor intensity of drainage workers is effectively reduced,the failure rate of equipment is reduced,and the level of automation and intelligence of drainage system is raised,so as to achieve the goal of energy saving,reducing staff and increasing effi-ciency.
