Development of hierarchical monitoring system of operating state of hydraulic support

  • 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.
