基于ARM的液压支架监测系统设计

Design of a monitoring system for hydraulic supports based on ARM

针对综采面液压支架监测参数多、传输距离远、难以实时安全监测等问题,设计了一种由ARM微处理器和CAN总线构建的井下液压支架监测系统。通过安装在液压支架上的压力、位移和倾角传感器,将液压支架的监测信息传送到数据采集分站,分站对采集到的数据进行预处理后,通过CAN总线传送到中心分站进行数据的进一步处理,并通过LCD和键盘构成的人机交互模块显示监测信息和故障报警,对实现液压支架的实时安全监测具有重要的实际应用意义。

Aiming at the problems such as excessive monitoring parameters,remote transmission distance and difficult real-time security monitoring of the hydraulic support in fully-mechanized faces,the paper designs a system for monitoring the hydraulic support that consists of ARM microprocessor and CAN bus. The various monitoring data of the hydraulic support are transmitted to the data collection substation via pressure,displacement and angle sensor installed on the support.After being processed in substation,the data are transmitted to the central substation via CAN bus for the further processing,meanwhile,the monitoring data and malfunction alarms are displayed via the man-machine interaction module composed of LCD and keyboard.The realization of real-time security monitoring of the hydraulic support has an important significance in practical applications.
