Abstract

The invention provides a WebRTC-based multi-terminal multi-channel real-time video monitoring method. The method comprises the following steps of: 1, configuring camera information according to an access mode of a camera video stream; 2, starting all back-end service programs to respond to a front-end video request, providing a unified video stream monitoring control service for a front end, and processing abnormal exit of a client; and 3, loading the configuration information and analyzing the configuration information into a configuration object by the front end, completing identity metadata interaction with the rear end, establishing end-to-end video data transmission based on WebRTC and completing video control; on the basis of the WebRTC protocol and the HTML5 technology, a unified and universal video protocol conversion service is provided, and various video data are converted into the WebRTC protocol to be directly used for a WEB page to play a video without a plug-in; and various video applications such as video inspection, video multicast, video carousel, video analysis and the like can be better completed.

Description

technical field [0001] The invention belongs to the field of urban rail transit, and can be specifically applied to the real-time monitoring of the closed-circuit television system (CCTV) of the integrated monitoring system (ISCS) of the urban rail transit industry, the real-time video monitoring of the security system, the real-time video monitoring of the emergency command system, and the operation and management of intelligent stations. System video surveillance and other fields. Background technique [0002] With the continuous deepening of Internet technology and information management technology and the continuous development of various application systems in the urban rail transit industry.
