3G wireless video monitoring system and video monitoring method thereof

Abstract

The invention discloses a 3G wireless video monitoring system and a video monitoring method thereof. The method comprises the following steps: establishing a 3G wireless data link between 3G wireless video monitoring equipment and a center server; after the link is successfully established, on a center server terminal, monitoring a request instruction of a monitoring terminal; if a parameter control instruction is received, forwarding to the 3G wireless video monitoring equipment; if an application video instruction is received and there is no a same kind of the monitoring terminal to perform monitoring, establishing an audio and video data transmission link with the monitoring equipment and forwarding to the new monitoring terminal after the audio and video data is received; otherwise, copying the audio and video data and forwarding to the new monitoring terminal; on a 3G wireless video monitoring equipment terminal, carrying out parameter adjusting according to the parameter control instruction; real-timely processing the audio and video data based on an image processing parameter of the monitoring terminal which is suitable for the current application video. By using the system and the method of the invention, a plurality of different monitoring equipment can simultaneously carry out real-time monitoring to a monitoring object.

Description

technical field [0001] The invention relates to the technical field of video surveillance, in particular to a 3G wireless video surveillance system and a video surveillance method thereof. Background technique [0002] Currently in the field of video surveillance in the transportation industry, vehicle-mounted DVS / DVR mainly only provides traditional video recording and real-time local preview functions, but cannot achieve remote real-time monitoring, especially for long-distance vehicles and dangerous goods vehicles. , The real-time status cannot be confirmed. With the popularization of 3G network, 3G wireless vehicle video monitoring system also came into being. In Chinese patent: application number CN200910098487.0, titled "vehicle 3G remote monitoring system and monitoring method" The camera terminal adopts a 3G communication module, sends an instruction to start the program through a 3G mobile phone to perform synchronous video recording and audio pickup, and directly ...

AI Technical Summary

Problems solved by technology

[0003] 1) The 3G network bandwidth is limited, and it is impossible for the camera terminal to send audio and video data to multiple mobile phone monitoring users at the same time. Even if it is sent, sending a piece of audio and video data multiple times will cause a waste of 3G network resources

[0004] 2) This technical solution is only limited to real-time monitoring using mobile phones, and the mobile phone needs to run uninterrupted, so the monitoring software can monitor in real time. Limited by the durability of the mobile phone battery, the mobile phone cannot work for a long time, such as shutting down and once There is an alarm, and the user cannot be notified in real time
