A parking management system needs to be designed to improve the efficiency of the management of parking lots in urban business districts that witness difficult parking. In this paper, the overall design of an intelligent parking system is expounded, the architecture of which includes the PXA270 master control platform, ZigBee network, the remote communication section and Android software; the LCD interface circuit is stated and the design philosophy for the analogue camera circuit is described. Meanwhile, the functions of the parking-space detection module and the vehicle identification unit are explained, and the structure diagram of the software in the intelligent parking system is put forward. Also, the design philosophies for the gate control unit and the GPRS communication program are expounded, a detailed definition of the control frame of the gate module is given, the flow charts of the parking-space status detection procedure and the vehicle identification procedure are presented, and the server of the Android system and the software design for the client are described. Furthermore, the flow chart of the network communication thread is put forward, in which data is transferred between the server and the client, the interface design for the intelligent parking system is realized, the display of the system’s main interface is presented, and the parking-space reservation interface and the function of entry guiding animation are realized.
