摘要
随着车辆日益增多,停车难问题突出,停车场难找,停车位更难找,找到停车场后由于车位信息不精确,位置不能定位,车主要耗费大量时间寻找车位。为了提高寻找车位的效率,降低成本,充分利用LED灯照明功能,利用可见光通信,搭建了基于可见光通信的停车场定位系统,通过红外测距辅助方式,把车位信息实时传输,车主利用定位信息可以有效地找到空车位。通过搭建的系统模型多次实验验证,车位信息获取和识别达到了100%,由于系统模型数量相对较少,存在一定误差,误差低于5%。
With the increasing number of vehicles,it is difficult to find parking lots and parking Spaces.After finding parking lots,cars spend a lot of time looking for parking Spaces because the parking information is not accurate and the location cannot be located.In order to improve the efficiency of looking for parking Spaces and reduce the cost,the parking lot positioning system based on visible light communication is built by making full use of LED lighting function,using visible light communication and precise positioning through ultrasonic.The parking space information is transmitted in real time and the car owner can find the vacant parking space in the shortest time.Through the system model built for several times of experimental verification,the acquisition and recognition of parking space information has reached 100%.Due to the relatively small number of system models,there is a certain error,the error is less than 5%.
