Highway video monitoring system

Abstract

The invention provides a highway video monitoring system. The video monitoring system comprises a plurality of cameras, a video convergence processing platform, a cloud service platform and a client,the plurality of cameras transmit acquired videos to the video convergence processing platform in real time. The video convergence processing platform processes the acquired multiple paths of real-time videos and then sends the videos to the cloud service platform system for storage, and after the client sends a video playing request to the web service node, the web service node obtains a video stream from the cloud service platform 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, video-on-demand can be carried out on the video data according to the required definition, the code stream can be multiplexed, the use of network bandwidth is reduced, the network performance is improved, a scheduling algorithm of convergence service nodes and server nodes is provided, the technical problems of inflexible scheduling and unbalanced load are solved, and the system performance is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a highway video monitoring system. Background technique [0002] China's national expressway network adopts a layout plan combining radial lines and vertical and horizontal grids. It consists of 7 capital radial lines, 9 north-south vertical lines, and 18 east-west horizontal lines. The main line is 68,000 kilometers, and other routes such as regional ring lines and connection lines are about 17,000 kilometers. It is the largest expressway system in the world. [0003] From January 2020, toll stations at provincial borders on expressways will be cancelled, and the existing closed toll collection model will be transformed into an open free-flow segmental toll collection model. Set up ETC masts in the road section before the traffic flow changes (such as entry / exit ramps, interchanges), and set up two masts (one set of equipment for each mast) in the up and down...

Problems solved by technology

[0004] However, the existing highway video monitoring system adopts a multi-level and multi-domain networking architecture, and uploads video data level by level according to the four-level network structure of "Ministry of Transport Center - Provincial Monitoring Center - Road Section Monitoring Center - Basic Monitoring Unit". There is a large data delay, video data cannot be on-demand according to needs, video data transmission occupies a large bandwidth, which affects network performance, and the scheduling between server nodes is not flexible, resulting in unbalanced load on service nodes and affecting system performance. Therefore, the existing highway video monitoring system cannot adapt to the needs of the above-mentioned new charging mode
