摘要:

针对汽车拥有量爆发式不断增长,停车位日益紧缺,而停车场管理落后导致其利用率低下的问题,设计出了一种基于ZigBee与地磁传感技术相结合的智能停车诱导系统。该系统采用地磁传感器技术检测停车场周围车辆分布,实时监测停车场周边交通信息;再结合ZigBee物联网技术,选用CC2530为主控芯片组网实现车位数据信息传输;在液晶显示屏(LCD)上实时发布停车场空闲车位数量与位置;再经四级诱导方式对车辆进行停车场外与场内引导,实现城市按需智能化停车。实验结果表明,系统可检车距精确度达到0.4m,在150m范围内采用增加路由器节点法实现0%掉包率的无线传输。该停车系统可提高车位利用率,减少车辆选择与停车时间,缓解城市车位紧缺,减少交通拥堵。

Abstract:

Concerning the phenomenon that common parking service could not satisfy the increasing demand of the private vehicle owners, an intelligent parking guidance system based on ZigBee network and geomagnetic sensors was designed. Real-time vehicle position or related traffic information was collected by geomagnetic sensors around parking lots and updated to center sever via ZigBee network. On the other hand, out-door Liquid Crystal Display (LCD) screens controlled by center sever displayed information of available parking places. In this paper, guidance strategy was divided into 4 levels, which could provide clear and effective information to drivers. The experimental results prove that the distance detection accuracy of geomagnetic sensors was within 0.4m, and the lowest loss packet rate of the wireless network in the range of 150m is 0%. This system can possibly provide solution for better parking service in intelligent cities.
