专家系统在铁路信号设备故障诊断中的应用

铁路信号设备在保证列车运行,提高运输效率,保证铁路运行秩序等方面起到重要作用,同时也成为保障铁路运输安全的关键所在。当前,对铁路信号设备故障的分析处理大多依赖于设备维护人员的经验,由于铁路大发展所造成的专业人员数量相对缺乏,有必要建造一个专家系统,作为铁路信号设备故障诊断的有效辅助工具。通过研究专家系统的一般原理,设计出一种适合铁路信号设备故障诊断的专家系统。通过铁路现场调试表明,该专家系统适用于国内铁路信号系统,对保障铁路运输安全有重大意义。

Application of Expert System to Railway Signal Appliance Fault Diagnosis

Railway signal appliance not only plays an important role to ensure the running of trains,improve transport efficiency,and keep the railway running order,but also become the key to protect the safety of rail transport.At present,the railway signaling appliance failure analysis and processing are mostly dependent on the experience of expert.Because of lack of professionals caused by the rapid development of the railway,it is necessary to build an expert system,which can be taken as an effective tool for diagnosis railway signal appliance failure.In this paper,by studying the general principles of the expert system,combining with the actual situation of the railway signaling system,it designes a suitable railway signaling appliance fault diagnosis expert system.Experiments show that the expert system is suitable for domestic railway signaling systems,and of great significance to the protection of rail transport security.
