本申请的技术方案，具体实施情况如下：The technical scheme of the present application, the specific implementation situation is as follows:
首先，在车辆前后左右四个边的中间位置各安装一个广角摄像头，使得单个摄像头就可以查看一侧的画面，并且各摄像头之间协作，确保不存在监控盲区。First of all, a wide-angle camera is installed in the middle of the front, rear, left, and right sides of the vehicle, so that a single camera can view the picture on one side, and each camera cooperates to ensure that there is no monitoring blind spot.
进而，将摄像头接入主机控制器，通过主机控制器转LVDS格式的监测视频图像，通过LVDS传到视频网络设备，通过网线用以太网格式连接到5G-CPE，再由无线网络连接基站；Then, connect the camera to the host controller, convert the monitoring video image in LVDS format through the host controller, transmit it to the video network device through LVDS, connect to the 5G-CPE through the network cable in Ethernet format, and then connect to the base station through the wireless network;
