| With the development of electronic information technology, microprocessor continue toenhance especially the performance of embedded chip, embedded system has also ushered in abroad prospects for development. With the rising of networking technology, wirelesscommunication technology makes real-time interconnection become a reality, which greatlyfacilitate the people’s lives. Embedded hand-held terminal based on wireless communication isdeveloped under this background. It is proved that the hand-held terminal applicated in parkingmanagement system can not only reduce the labor cost effectively, but also achieving the parkinglot management information and intelligence.Embedded hand-held terminal based on wireless communication has the functions of RFIDinformation reading, vehicle information processing and displaying, real-time data transmissionand so on. For the outside vehicle, we charge and manage the vehicle with RFID card; we onlyregister the internal vehicle when they drove to the door. Parking handsets match with hardwaremodule of vehicle management system, such as automatic barrier, sense coil, control panel, whichrealizing parking management intelligence.This paper implements the design of hardware of handsets, the migration of embeddedoperating system, drive configuration and the development of GUI programs. We use Samsung’sS3C6410as central processor of the hardware part. We also designed Flash memory circuit, powercircuit, JTAG debugging interface circuit and the USB interface circuit, RFID circuit based on MFRC522, wireless communication circuit based on88W8686, LCD display circuit, we also analysiselectromagnetic compatibility should pay attention. We migrate U-boot and Linux operatingsystems for the hand-held terminals, we also build the appropriate file system. Drive configurationpart includes Flash drive, USB drive and Wi-Fi drive, and completed the development of GUIapplications finally.After tested, the device is working properly, stable and reliable. |
