Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0031] Such as figure 1 As shown, the preventive prompting method for the abnormal temperature of the EMU axle of the present embodiment includes: S1. Obtaining the temperature values ​​of the same measurement parts of the different axles of the EMU through sensor measurement; S2. Divided into credible sensors and unreliable sensors; S3. Calculate the average value of the temperature value obtained by the credible sensor; S4. When the difference between the temperature value obtained by the sensor and the average value is greater than the preset early warning threshold, judge that the EMU should If the temperature of this part of the axle is abnormal, an abnormal warning signal will be issued.

[0032] In this embodiment, the division rules preset in step S2 in...

Abstract

The invention discloses a preventive prompting method and system for abnormal temperature of an EMU axle. The method includes: S1. Obtaining the temperature values ​​at the same measurement position of different axles of the EMU through sensor measurement; S2. According to the temperature value according to the preset division rule Divide the sensors into trusted sensors and untrusted sensors; S3. Calculate the average value of the temperature value obtained by the trusted sensor; S4. When the difference between the temperature value obtained by the sensor and the average value is greater than the preset early warning threshold, judge the motor vehicle If the temperature of this part of the axle is abnormal, an abnormal warning signal will be issued. The invention has the temperature of the same part of the different axles of the EMU as the basis for judging the temperature abnormality early warning, can carry out full-range early warning monitoring on the temperature of the EMU axles, timely discover the hidden dangers of the abnormal temperature of the EMU axles, issue early warning prompts, and guide maintenance Timely maintenance by personnel can effectively reduce the occurrence of axle temperature alarm events and ensure the safe operation of EMUs.

Description

technical field [0001] The invention relates to the field of monitoring and controlling the temperature of an EMU axle, in particular to a preventive prompting method and system for abnormal temperature of an EMU axle. Background technique [0002] The EMU shaft temperature detection system measures the temperature at a specific position of the bogie to monitor whether the bogie is normal, and if the temperature is abnormal, the driver is notified to limit the speed or stop. In actual use, due to the large number of measurement points, any abnormality in any part will affect the normal operation of the vehicle. The existing shaft temperature system abnormal alarm adopts a fixed early warning threshold value (alarm threshold value). When the temperature measured by the sensor exceeds the fixed early warning threshold value (alarm threshold value), an early warning (alarm) is issued. This kind of early warning or alarm method belongs to post-warning (alarm). After the early w...
