Application of Hydraulic Support Automation Monitoring System
SUN Zhiyong
Abstract：In response to the problems of low efficiency and high labor intensity in the existing control methods of hydraulic supports in Xiegou coal mine,automation transformation of the existing hydraulic supports was carried out,the overall scheme and basic functions of the support control system were analyzed,Siemens PLC S7-200 controller,support controller and various sensors were selected,and data through RS485 and CAN bus communication methods was transmitted,which can operate stably in harsh environments underground in coal mines.In addition,the system has designed a single frame workflow and a sequential linkage workflow,realizing the automatic control function of the hydraulic support's lowering and lifting cycle by grouping the supports.The results showed that the system effectively reduced labor costs and equipment failure rates,saving 1.1 million yuan in labor costs and equipment maintenance costs annually.The measured error was controlled within 10％,improving the safety and work efficiency of the system,and had certain reference significance for coal mine technology upgrading.
