After the Ministry of Public Security implemented the new reforms to streamline administration and delegate power, improve regulation, and upgrade services, a vehicle inspection service platform was designed to solve the problems raised by the majority of car owners regarding the annual inspection of motor vehicles, such as the difficulty of vehicle inspection, high costs, congestion in inspection stations, and lack of time. This study focuses on the study and implementation of the business process and function structure of the vehicle inspection service platform. Specifically, interactions with vehicle owners can be achieved by means of mini programs, and vehicle inspection status can be identified through Internet of Things technology. Drivers and inspection station employees can participate through the mobile APP, and multiple parties such as vehicle owners, drivers, and inspection stations can be integrated through the service platform. The test results show that the system integration test and performance test results are good and can meet the actual application requirements. The online trial shows that the vehicle inspection service platform can to a certain extent solve the practical problems of vehicle owners’ difficulties in vehicle inspection and the uneven distribution of inspection stations, boasting bright application and promotion prospects.
