基于4G网络的车辆防盗视频传输系统设计

Real-time video transmission system design of vehicle anti-theft based on 4G

针对车辆监控报警有效距离短、方式单一等问题,提出一种基于4G网络的监控视频实时传输系统设计方法。该系统以STM32为主控制器,检测到车辆异常时,系统自动启动高清摄像头进行视频图像采集,输出的视频经过RJ45-USB转换模块转换为USB数据类型,主控制器控制4G无线传输模块将监控视频数据上传至服务器,用户利用移动终端访问服务器可以自动获得车辆的实时异常状态信息。实验证明:基于4G网络的车辆防盗视频传输系统具有实时性,传输视频分辨率可达720 P,在车辆防盗系统领域应用广阔。

To solve the problems of the single mode and short transmission distance in the vehicle surveillance and anti-theft system, the paper proposes a design of the real-time video transmission system based on 4G network. Taking STM32 as the core processor, the system opens HD camera to capture video automatically when the vehicle is detected, and then the video data will be transformed into the USB data type by R J45-USB conversion module. The digital signals are sent to the server by 4G module, so the abnormal state information of the vehicle can be shown by mobile terminal of users. Experiments show that the video transmission system of the vehicle anti-theft based on 4G networks has real-time and transmission video can reach 720P, which has wide application in the field of vehicle anti-theft.
