基于智慧城市光储充一体化停车棚的共享充电服务系统，在工作时，首先摄像头实时录制进入停车棚内的车辆的视频信息并将视频信息通过Zigbee无线网络传输到控制器，音频采集模块采集车辆的音频信息并将车辆的音频信息传输至控制器；所述数据分析模块用于接收车辆的视频信息和车辆的音频信息并对视频信息和音频信息进行识别分析，识别进入的车辆是汽油车还是电动车；如果是汽油车，则发出警告显示，提醒汽油车离开不要私占充电桩的充电位，地锁保持展开状态；通过采集经过的车辆的视频信息和音频信息，识别车辆是否有排气管及分析音频内容，来判断车辆是电动车或汽油车，解决了充电桩被汽油车占车位的问题，具有设备简单，检测数据准确的优点；The shared charging service system based on the smart city light storage and charging integrated parking shed, when working, the camera first records the video information of the vehicle entering the parking shed in real time and transmits the video information to the controller through the Zigbee wireless network, and the audio collection module collects the video information. The audio information of the vehicle and the audio information of the vehicle are transmitted to the controller; the data analysis module is used to receive the video information of the vehicle and the audio information of the vehicle, and identify and analyze the video information and audio information, and identify that the entering vehicle is a gasoline vehicle It is still an electric vehicle; if it is a gasoline vehicle, a warning display will be issued, reminding the gasoline vehicle not to occupy the charging position of the charging pile privately, and the ground lock will remain in the unfolded state; by collecting the video information and audio information of the passing vehicles, it can identify whether the vehicle has a row The trachea and analysis of the audio content can determine whether the vehicle is an electric vehicle or a gasoline vehicle, which solves the problem that the charging pile is occupied by a gasoline vehicle, and has the advantages of simple equipment and accurate detection data;
当电动车的充电线与充电桩相连接进行充电时，所述数据采集模块用于采集电动车的电池数据并将电动车的电池数据传输至故障预测模块；获取直流充电状态下流经电池的实时电流值、实时电压值；得到所述电池在直流充电状态下的电阻值R0；根据所述电池在直流充电状态下的电阻值R0及所述电池在出厂时的直流充电电阻值R1获取所述电池的危险系数LH；若LH大于等于预定值，则评估所述电池处于危险状态，发出预警信号，提示车主更换电池；若LH小于预定值；则将生产时长、使用时长和危险系数进行去量化处理并取其值，利用公式
上述公式均是由采集大量数据进行软件模拟及相应专家进行参数设置处理，得到与真实结果符合的公式。The above formulas are obtained by collecting a large amount of data for software simulation and corresponding experts for parameter setting processing, and obtaining formulas that are consistent with the real results.
