Abstract：In view of problem that current condition monitoring system of hydraulic supports has low concentration degree of parameters monitoring and cannot provide real-time data for local and centralized control at the same time,a hierarchical monitoring system of operating state of hydraulic support based on RS485 communication network was developed.The system adopts support controller to gather running parameters of each sensor in real-timely and send the operation parameters to adjacent support controller on working face through the RS485 communication,so as to provide real-time data for local control;At the same time,the system uses the RS485 communication to send the operation parameters to end controller and centralized control computer,so as to provide real-time data basis for centralized control.The results of underground industrial test show that the system can realize functions of continuous acquisition,real-time uploading and centralized management of hydraulic support operating parameters,meets the needs of mine actual production.
