Abstract: At present, there is a lack of safety control means for anti slip operation in the field of railway vehicle service system, which usually adopts manual means. Starting from the field demand, this article combed the existing anti sliding operation process, studied the safety protection system of railway vehicle slip based on the low power Internet of Things technology, implemented the whole process monitoring of anti sliding operation, and avoided the traffic accidents caused by the missing installation and removal of anti sliding devices. The practice shows that the system can effectively improve the standardization degree of anti sliding operation, reduce the labor intensity of shunting operators, and provide an effective solution for the current management difficulties of anti sliding operation in stations.
