一、轴温检测系统的功能和程序流程图列车在运行时,轮轴发热是正常现象,一般都在允许温限之内。但有时个别轴温超过限度,而车上工作人员不能及时发觉,以致发生严重事故。机车轴温检测工作,一般是在车下进行的,而且常凭手感来判断轴温的高低,所以很不准确。目前已在某些铁路区段采用先进的测试技术,即在轨道两侧安设红外线测温装置,当
First, the shaft temperature detection system functions and program flow chart Train operation, the wheel axis fever is normal, are generally allowed within the temperature limit. But sometimes the individual axis temperature exceeds the limit, and the car staff can not be found in time, resulting in serious accidents. Locomotive shaft temperature testing, usually carried under the car, and often feel the shaft temperature to determine the level, it is not accurate. At present, some advanced test technologies have been used in some railway sections, that is, infrared temperature measurement devices are installed on both sides of the track.
