| 摘 要： | 针对路边停车存在的问题，提出了一种基于ZigBee＋GMR的车辆检测系统。首先，利用巨磁电阻传感器的巨磁效应检测车辆相关信息，并通过单片机处理数据以检测车辆的存在和识别车辆的类型；接着，利用新型的短距离无线接入技术ZigBee将得到的数据传输到手持式收费机，使手持式收费机准确记录车型和停车时间；最后，通过手持式收费机再将车位占用信息传送给路边控制器，从而实现路边停车位数量的显示和对停车位停车状态的查询。

| Abstract: | According to the problems of roadside stop, a vehicle detection system based on ZigBee and GMR is designed. In this paper, the giant magnetoresistanee effect of giant magnetoresistanee （GMR） sensors is used to detect vehicle information. The existence of a vehicle and the vehicle classification can be detected by processed data of MCU, and MCU uses ZigBee, which is a new kind of wireless access technology, to transmit the processed data to a portable charging machine. And then the portable charging machine transmits the information of parking occupancy to the roadside controller, So it can display the number of parking spaces and query parking status. At the same time, the vehicle detection system can make the portable charging machine record the vehicle type and parking time accurately. |
