Development Of An Embedded System Based On STM32 And Application On Vehicle Management

Currently, embedded development platforms are integrated, the hardware layout is compact, functional module division is not clear. This paper presents a modular decomposition embedded development platform, the hardware will be a clear division of each function. This article will be divided into embedded hardware system design for the core board and expansion modules, core board that is the smallest embedded systems, expansion modules that are connected to the STM32 processor interface, a generic I / O module, a CAN and RS232 module and a sensor module have been completed and interface of the core board and expansion modules all lead out to developers so that we can master interface design and drive development.In this paper, a double cards identification vehicle management system software design based on RFID long-range reader on STM32F107 hardware platform and u C / OS-II operating system has been completed. The vehicle identification management can be classified by this software, the vehicle are classified to private cars and utility cars of this unit, private cars by staff card access control, public cars using the matched personnel card and vehicle card to get composite card access control, through artificial control access to foreign vehicles. System enables automatic vehicle access card reader, vehicle access rights verification, vehicle traffic records preservation. The system through the connection with remote server, receiving various types of communication instruction issued by the server to update and maintain the library card, and can upload vehicle traffic records locally stored on time, the system also enables human-computer serial port function to achieve the relevant parameters configure and change.
