Problems solved by technology

[0004] In order to better manage the operating vehicles, urban transportation departments or enterprises engaged in public transportation, it is the general trend to install a Beidou / GPS-based wireless video monitoring system on each operating vehicle; however, the real-time audio and video data transmission of a large number of operating vehicles will It consumes a lot of network bandwidth and costs, and at the same time brings a lot of processing overhead to the video surveillance background, which in turn delays the process of deploying a Beidou / GPS-based wireless video surveillance system for operating vehicles

Embodiment 1

[0034] This example provides an efficient transmission system for vehicle wireless video surveillance, including:

[0035] The video surveillance vehicle front-end is used for real-time capture and digital collection of various information on the vehicle site, including the Beidou / GPS positioning information of the vehicle, audio and video information collected by multiple cameras and pickups, and alarm status information and sensor information;

[0036] Vehicle-mounted information recording platform, the vehicle-mounted information recording platform records and processes the information collected by the video monitoring vehicle front-end, including encoding audio and video data;

[0037] A vehicle information fusion module, the vehicle information fusion module fuses the collected Beidou / GPS positioning information with sensor information and audio and video information respectively to form sensor information and audio and video information with position positioning;

[003...

Embodiment 2

[0052] Such as figure 2 As shown, on the basis of Embodiment 1, the vehicle information fusion module described in this example uses script commands in the video encoding process to realize the fusion of real-time Beidou / GPS positioning information and audio and video information, and first inserts positioning information into audio and video frames. The information script finally writes the positioning information into the audio and video data, and then realizes the fusion of positioning information and audio and video information.

[0053] The encoding method of the collected audio and video information data is realized by the vehicle-mounted terminal encoding chip. At present, it is mainly the encoding and compression format of H.264. Of course, it can also be adjusted to other encoding and compression formats as needed.

[0054] In this example, the interpolation method is used to match the positioning information with the audio and video information. First, the obtained ...

Abstract

The invention provides a high-efficiency transmission system for vehicle wireless video monitoring. The high-efficiency transmission system comprises a video monitoring vehicle-mounted front end for capturing and digitally acquiring various pieces of information in real time, a vehicle-mounted information recording platform for recording and processing the acquired information and encoding audio and video data, a vehicle information fusion module for respectively fusing acquired beidou / GPS (global positioning system) positioning information with sensor information and audio and video information to form sensing information and audio and video information which are provided with the positioning function, a vehicle-mounted information management module for managing the recorded information, and a monitoring center, wherein the beidou / GPS positioning information of a vehicle is transmitted to the monitoring center in real time, and the audio and video information is dynamically transmitted and controlled according to an actual running condition of the vehicle and a requirement of the monitoring center. According to the high-efficiency transmission system for the vehicle wireless video monitoring, a wireless transmission requirement can be greatly reduced; under a condition of guaranteeing the running safety, the running cost is reduced, and the high-efficiency transmission is realized.

Description

technical field [0001] The invention relates to a monitoring transmission system, in particular to an efficient transmission system for vehicle wireless video monitoring. Background technique [0002] At present, most vehicles have been installed with navigation and positioning devices to realize real-time tracking of vehicle positions. Some vehicles have also been installed with on-board wireless audio and video monitoring equipment. Through wireless audio and video monitoring, the operating conditions of operating vehicles can be understood and recorded in real time. . [0003] The vehicle wireless audio and video monitoring system is often composed of three parts: video monitoring vehicle front-end system, transmission network and video monitoring background system. The operating vehicle and the monitoring and management center realize two-way data communication. The operating vehicle uploads real-time information including vehicle location, status, and collected voice ...
