Data processing method of expressway video monitoring system

The invention provides a data processing method of an expressway video monitoring system. The method comprises the steps that a plurality of cameras transmit collected videos to a video gathering andprocessing all-in-one machine in real time; the video gathering and processing all-in-one machine processes the acquired multiple paths of real-time videos and then sends the videos to the cloud service system for storage, and the cloud service system comprises a plurality of cloud server nodes; and the video aggregation processing all-in-one machine receives the video playing request of the client and then obtains the video stream from the cloud service system according to the playing request and sends the video stream to the client for playing. According to the invention, the technical problem of large data delay of the existing expressway video monitoring system is solved; according to the invention, video-on-demand can be carried out on the video data according to the required definition, the code stream can b
