摘要
针对煤矿现有带式输送机监控系统可靠性差、常见故障定位困难等问题,设计了一种基于RS485和CAN总线的具有故障定位功能的带式输送机监控系统。根据现场运行情况,确定了系统监测量和控制量,完成了系统总体设计方案,设计了急停模块、扩音电话、下位机和终端模块,编写了故障综合判断程序,并提出了基于RS485和CAN总线的常见故障定位方法。试验结果表明:该系统具有监控功能完备、故障定位准确、通信实时可靠等特点,能够满足煤矿生产实际需要。
Aiming at the poor reliability, difficult common fault location of current belt conveyor monitoring system in coal mine, a belt conveyor monitoring system with fault location function was designed based on RS485 and CAN bus. According to the site operation situation, the monitoring quantities and control quantities were determined, the overall design scheme was completed, the emergency stop module, amplify telephone, lower computer and the terminal module was designed, the fault comprehensive judgment procedure was compiled, and a common fault location method based on RS485 and CAN bus was presented. The test results show that the system realizes complete monitoring and control, accurate location and reliable communication, which meets the needs of coal mine production.
