【摘要】：目前,嵌入式开发平台都是集成式的,硬件布局比较紧凑,功能模块划分不清晰。本文设计了一种分解式模块化嵌入式开发平台,从硬件上将各功能明确划分。本文将嵌入式硬件系统的设计划分为核心板和拓展模块,核心板即嵌入式最小系统,拓展模块即与STM32处理器接口连接的功能模块,完成了通用I/O模块、CAN and RS232模块、传感器模块,并将核心板和拓展模块的接口全部引出来,以便开发者掌握处理器的接口设计及驱动开发。本文在STM32F107硬件平台与uC/OS-II操作系统上完成了一种基于RFID远距离读卡的双卡识别车辆管理系统软件设计。此软件可以对进出车辆进行分类识别管理,进出车辆分为单位私家车和单位公用车,对单位私家车按人员卡控制进出,对单位公用车辆采用人员卡与车辆卡匹配生成的复合卡控制进出,外来车辆通过人工控制进出。系统实现了通行车辆自动读卡,车辆通行权限验证,车辆通行记录的本地保存。本系统通过与远端服务器建立通信,接收服务器下达的各类指令进行卡片库的更新及维护,并且可以按时上传本地保存的车辆通行记录,系统还实现了人机串口功能,可以对相关参数进行配置及更改。
[Abstract]:At present, the embedded development platform is integrated, the hardware layout is compact, the function module division is not clear. A decomposed modular embedded development platform is designed in this paper. In this paper, the design of embedded hardware system is divided into core board and expansion module. The core board is the embedded minimum system, the expansion module is the function module connected with STM32 processor, and the general I / O module, CAN and RS232 module is completed. Sensor module, and the core board and expansion module interface all out, so that developers can master the processor interface design and driver development. In this paper, the software design of dual card recognition vehicle management system based on RFID remote reading card is completed on STM32F107 hardware platform and uC/OS-II operating system. The software can classify and identify the incoming and outgoing vehicles, which are divided into unit private cars and unit public vehicles, and control the entry and exit of unit private cars according to the personnel card. For public vehicles, the personnel card and the vehicle card are used to control the entry and exit, and the external vehicles are manually controlled in and out. The system realizes the automatic card reading of vehicles, the verification of vehicle access authority, and the local preservation of vehicle traffic records. The system can update and maintain the card library by establishing communication with the remote server, receiving all kinds of instructions from the server, and uploading the local vehicle traffic records on time. The system also realizes the man-machine serial port function. Related parameters can be configured and changed.
