Research and design of intelligent parking management system based on UML technology

With the rapid development of Internet of Things (IoT) technology, IoT technology has become popular in many fields and has effectively improved the work efficiency in practical applications. In the current operation of the parking lot, the gradual increase of IoT devices has caused a certain degree of management difficulties, based on this current situation, this paper designs a parking lot management system with IoT device management function, which has three subsystems, corresponding to IoT The management system has three sub-systems, which correspond to IOT device information management, vehicle information management and management personnel information management. This paper analyzes the current situation and development trend of the parking lot, analyzes the requirement analysis and use case diagram modeling based on UML technology, then carries out the system architecture design and data structure analysis, and finally does the process design for the core functions of the parking lot.
