为了实现基于ARM的停车场车辆管理系统，本文采用 Cortex-M3内核的 STM32微控制器，以此为核心部署了超声波模组作为车辆检测器，液晶屏作为信息显示器，步进电机作为道闸控制器，以及智能卡读写器。为了便于管理员使用，在PC上用VB编写了图形界面，配合Access数据库通过串口对系统进行管理。测试系统功能结果能够完成车辆在停车场的进出场流程，由此验证了该套低成本解决方案的可行性，实用性。%To implement the parking lot management system based on ARM,the Cortex-M3 STM32 microcontroller is used as a core to deploy the ultrasonic modules as vehicle detectors. In the system,a smart card reader is used,and LCD screen is taken as a information display and stepper motor as a barrier controller. In order to facilitate administrators to use,graphical in-terface on a PC was compiled with VB. The system is managed through the serial port and the Access databasement. Test results show that the system functions of the entry and exit parking lot procedures of vehicles can be completed. The feasibility and prac-ticality of this low-cost solution were verified.
