背景技术Background technique

随着汽车产业的飞速发展，城市泊车难的问题愈来愈突出，改善泊车设施，收集与共享各停车场车位占用与停车位置的实时信息，提高泊车与取车效率已迫在眉睫。目前，大多数停车场都是由停车场工作人员对停车位分区管理，这样的停车场管理方式处产生如下问题：With the rapid development of the automobile industry, the problem of difficult parking in cities has become more and more prominent. It is imminent to improve parking facilities, collect and share real-time information on the occupancy and location of parking spaces in each parking lot, and improve the efficiency of parking and picking up cars. At present, most of the parking lots are managed by the parking lot staff to divide the parking spaces. This kind of parking lot management method has the following problems:

1.城市的一个区域中，有的停车场可能车位已满，但车主因无法预先得知该停车场的车位状况而进入该停车场，不但无法停车，而且还会导致该停车场通道拥堵、空气环境恶劣等问题；同时，有的停车场可能存在大量空置车位，车主因无法预先得知该停车场的车位状况而没有进入该停车场，致使该停车场车位空闲，使该停车场车位利用率低。1. In an area of the city, some parking lots may be full of parking spaces, but the owner enters the parking lot because he cannot know the parking space conditions of the parking lot in advance. Poor air environment and other problems; at the same time, some parking lots may have a large number of vacant parking spaces, and the owner did not enter the parking lot because he could not know the parking space conditions of the parking lot in advance, resulting in the parking space being empty and making the parking space useless. low rate.

2.当车主返回停车场取车时，由于停车场内部状况比较复杂，或者遗忘自己车辆的停车位置时，车主往往难以快速准确找到自己车辆，造成时间浪费。2. When the car owner returns to the parking lot to pick up the car, due to the complex internal conditions of the parking lot, or when he forgets the parking position of his vehicle, it is often difficult for the owner to find his car quickly and accurately, resulting in a waste of time.
