Abstract: In the era of high-quality development, the combination of public transportation, intelligent networking, and high-tech has become the mainstream trend of urban transportation development. In order to achieve more efficient safety management of pure electric buses, the article focuses on the analysis of the relationship between the battery, motor, vehicle controller and vehicle performance, and determines the safety technologies that need to be monitored during the driving process of pure electric buses, parameters, constructed a BP neural network security evaluation model, and finally designed a remote monitoring system with 5G communication technology as the core based on the characteristics of 5G high speed and low delay, which can not only improve the accuracy of data collection and data transmission. It can also achieve comprehensive safety monitoring to ensure the driving safety and reliability of the vehicle. The research results show that the system realizes comprehensive remote monitoring and status evaluation of pure electric buses, and realizes relatively efficient and stable data transmission during vehicle operation, which has certain development and utilization value.
