摘　　要：针对目前煤矿安全监控系统存在的通信实时性差、可靠性不高、易受电磁干扰等问题,提出了一种数字式煤矿安全监控系统设计方案,介绍了系统软、硬件设计方案及关键技术。该系统基于CAN总线和工业以太环网的双重冗余结构,以ARM处理器LPC2294和嵌入式操作系统μC/OS-Ⅱ为核心。测试结果表明,在10km CAN总线,32个数字分站,200台传感器、执行器规模下,该系统CAN总线通信成功率为99.97%,利用率为40%~60%;系统连续运行40d,数据稳定,无中断、异常数据产生,技术指标符合AQ 6201—2006《煤矿安全监控系统通用技术要求》。For poor real-time communication, stability and anti electromagnetic interference performance of existing coal mine safety monitoring and control system, a digital coal mine safety monitoring and control system was proposed, and hardware scheme, software scheme and key technologies of the system were introduced. The system adopts dual redundancy structure of CAN bus and industrial Ethernet ring network, and takes LPC2294 ARM processor and μC/OS-Ⅱ embedded operation system as cores. The test results show that communication success rate of CAN bus is 99.97% as well as utilization ratio is 40%-60% of the system with 10 km CAN bus, 32 digital substations and 200 sensors and actuators. The system can run 40 days continuously with stable data communication and without interrupted and abnormal data, and technique indexes of the system meet requirements of AQ 6201-2006 General technical requirements of coal mine safety monitoring and control system.
