Research of Mine Drainage Automatic Control System Based on PLC

摘要

According to the development of mine automation requirements,Siemens S7-300 PLC is adopted in order to do the research of mine drainage automatic control system in this paper.Combined with frequency control technology,the system can schedule the pumps reasonably by monitoring water level and pressure signals.With failure alarm,group network communication and other functions,it's profitable to achieve the whole mine automatic control and the economic operation of the entire system.
