An early warning system of tram safety protection based on multi-information detection

Abstract

Aiming at the existing collision accidents with motor vehicles and pedestrians in the operation of tram, a tram safety protection early warning system is proposed, which can automatically analyze and interpret dangerous objects in the direction of moving forward. The system uses ranging sensor (Ultrasonic, Camera, Ranging radar) and infrared video information to obtain the accurate distance between the obstacle and the locomotive. The obstacle type and potential running speed can be obtained by infrared image recognition and classification. According to the direction of the tram, the distance, type and speed of the obstacles, the safety level of the obstacles can be determined. The above analysis and interpretation results are displayed intuitively on the on-board display and reminder unit. Relevant technologies can effectively improve the ability of the tram driver to obtain information, automatically detect obstacles and judge the degree of danger, and improve the safety of the tram.
