摘要
针对现有液压支架状态监测系统参数监测集中程度低,不能同时为就地控制和集中控制提供实时数据的问题,研制了一种基于RS485通信网络的液压支架运行状态分级监测系统。该系统通过支架控制器实时采集各个传感器的运行参数,通过架间RS485通信将运行参数传输至工作面相邻支架控制器,为就地控制提供实时数据;同时,通过RS485通信将运行参数传输至端头控制器和集控计算机,为集中控制提供实时数据依据。井下工业性试验结果表明,该系统可实现液压支架运行参数的连续采集、实时上传、集中管理等功能,满足井下实际生产的需要。
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.
