摘　　要：煤矿安全监控系统数字化升级改造,可使其安全性、稳定性显著提高,而作业环境、系统软硬件和人为操作等因素仍会导致数据采集、处理和网络传输出现异常,因此需要在系统关键环节设置故障自诊断单元。根据煤矿安全监控系统配置特点和运行维护实际需求,将系统划分为3个层级:感知层、传输层、平台层,针对各层级存在的问题,从软硬件方面,研究设计了故障自诊断模块,指出各模块应具备的功能。现场应用试验表明:层级故障自诊断技术能有效改善信息交互、数据传输质量,提高煤矿安全监控系统的可靠性。The digital upgrade and transformation of the coal mine safety monitoring system have significantly improved its safety and stability,but the operating environment,system software and hardware,human operation and other factors still lead to abnormal situation,such as data collection,data processing and network transmission,so it is necessary to set the fault self-diagnosis units in the key links of the system.According to the configuration characteristics of coal mine safety monitoring system and the actual requirements of operation and maintenance,the system is divided into three levels:perception layer,transmission layer and platform layer.In view of the problems existing in each level,the fault self-diagnosis module is studied and designed from the aspects of software and hardware,and the functions of each module are pointed out.The field application test shows that the hierarchical fault self-diagnosis technology can effectively improve the quality of information interaction and data transmission,and improve the reliability of coal mine safety monitoring system.
