Research on the Alarm Method of PHM of the Train

At present, the PIS (Passenger Information System) system of the high-speed EMU only realizes the real-time monitoring function of the electric bow video. When a bow spark, abnormal bow and foreign body impact, the PIS display will pop up a fault alarm information. After seeing the alarm information, the passenger personnel searched historical videos in the PIS system through the failure time. Because the staff needed manual retrieval, the video information of the critical moment of the fault was unable to obtain the critical moment of faults, resulting in the efficiency of obtaining and disposing of electrical bow faults in the obtaining and disposal of the maintenance and maintenance personnel. In order to solve the above problems, this article proposes a new method of alarm alarm by electric bow failure. After the PHM is subject to early warning and alarm, it will automatically save and push the videos before and after the alarm. Accurately and efficiently obtain the fault information and deal with it.
