铁路车辆红外线轴温检测是铁路行车安全的重要内容,然而红外线轴温检测设备故障牵扯到车辆、供电、通信3个部门,而且红外线工区、通信工区、电力工区管辖范围较长,出了问题三家都需出动,必然耗费大量的人力和物力。根据现场维护经验,95%的故障是供电和红外线设备造成,通信造成的故障只占5%,因此进行通道故障远程诊断,对节省人力、物力和财力非常必要。 Infrared axis temperature detection of railway vehicles is an important part of railway traffic safety. However, the failure of infrared axis temperature detection equipment involves the three departments of vehicles, power supply and communication. In addition, there are three problems in the infrared area, communication area and power area All need to be dispatched, inevitably consuming a lot of manpower and material resources. According to field maintenance experience, 95% of faults are caused by power supply and infrared equipment, and only 5% of faults caused by communication. Therefore, remote diagnosis of channel faults is very necessary to save manpower, material and financial resources.
