摘　　要：针对井下胶带输送机控制系统实时动态监控的需要,介绍了一种基于ARM7嵌入式微处理器的井下胶带输送机控制系统。以LPC2138为核心,采用速度传感器、烟雾传感器、温度传感器、撕裂传感器、堆煤传感器、急停闭锁开关和跑偏传感器等进行实时在线监测和控制。采用全分布式控制结构,利用CAN总线实现各分站及分站与主站之间的通讯。本文有效地将LPC2138强大的管理功能和自带的CAN总线的优点结合起来,使得通信部分能有效地将数据发送到矿井调度室。试验结果表明:系统控制精度高、操作简单、实时性好。To meet the need of real-time and dynamic monitoring, Belt conveyor control system of coal mine underground based on ARM7 embedded microprocessor is introduced. LPC2138 as the core, using speed sensors, smoke sensors, temperature sensors, tearing sensors, coal heap sensors, emergency stop switch and latch deviation sensors for real-time online monitoring and control. A fully distributed control structure, the use of CAN bus communication to achieve the sub-stations and sub-stations and the main station. Combining the powerful management of LPC2138 and the advantages of CAN BUS, which makes the communication can ef-fectively send data to the mine control room. The experiment results show that this system has features with high precision, simple operation and real time.
