基于ARM与WSN的嵌入式智能停车管理系统研发

摘要

研究基于嵌入式的停车场管理系统，采用Cortex A8处理器OMAP 3530代替PC机，并在其上运行嵌入式Linux操作系统，采用QT Creator进行程序开发，构建智能停车管理主机平台，极大降低人为随意操作带来的风险。利用超声波对车位使用情况进行定时检测，采用ZigBee模块构建WSN无线网络，并自主设计无线路由协议，将检测到的车位使用情况实时上传到管理主机，实现对每个车位的实时监控，并通过LED指示灯及显示屏的方式发布车位使用情况，实现停车路线的无人引导。%A research based on embedded parking lot management system is carried out using OMAP 3530 Cortex A8 processor instead of the PC and an embedded Linux operating system. Using QT Creator program development, an intelligent parking management host platform is built, which greatly reduces man-made risks. The ultrasound wave is used to detect the use of parking space, the ZigBee module is used to construct the WSN wireless network and the wireless routing protocol is designed, which can transfer the real-time message to the management host for real-time monitoring. The usage of parking space can be displayed through LED and display screen, which makes it possible for the accomplishment of an unmanned guidance for parking.
