摘要随着各个大中小城市汽车拥有量的爆发式增长，现有停车场数量已经不能满足人们的需求，停车难问题日益加剧。许多现有停车场系统存在的问题是停车位信息无法进行有效发布，驾驶人员不能远程获取当前各个停车场的停车位剩余数量，只有驾车到达目的地后才能知道该停车场是否能够停车。因此本文提出了一种基于地磁感应的无线智能停车系统。 该系统通过地磁传感器实时监控停车场各个停车位的占用情况并利用MAG3110芯片采集停车位信息，将采集到的车位信息通过无线传感器网络进行传输，传输的信息经过分析处理，发布到停车场的电子引导屏上，从而引导驾驶人员快速、有效地找到空闲停车位，提高了停车场使用效率，一定程度上缓解了交通压力，方便了人们的出行。41523

Title Research and Development on Wireless IntelligentParking System based on Geomagnetic Induction
Abstract With explosive growth of car ownership in various cities and towns, the numberof existing parking lot can not meet people's needs and the parking problem becomesmore and more serious. Many existing parking system have the problem that theparking information can not be effectively released. Then, drivers can not remotelyget the current remaining number of parking spaces for each parking lot. They canonly know whether the parking lot can park after reaching the destination. To solvethe above-mentioned problems, this paper proposes a wireless intelligent parkingsystem based on geomagnetic induction. The parking system real-time monitorsoccupancy of each parking space and acquires parking information by chip MAG3110in geomagnetic sensor. These collected parking information will be transmittedvia wireless sensor networks. Then, the transmitted information will be analyzedand processed .After that, it will be published to the electronic guidance screenin parking lot in order to lead drivers quickly and efficiently to find a freeparking space. It improves utilization of the parking lot and alleviates thetraffic pressure to some extent. All of this can facilitate people's travel.
