Train streaming media transmission device and video monitoring system

Abstract

The invention relates to a train streaming media transmission device and a video monitoring system. The train streaming media transmission device comprises a data transmission unit, a communication interface unit connected with the data transmission unit and a power supply interface unit, and the power supply interface unit supplies power to the data transmission unit. The data transmission unit is provided with a data acquisition module for acquiring real-time state data and video images of a train; a region management module used for extracting image information needing to be superposed fromthe train real-time state data, setting the image information as an OSD image and carrying out superposition processing on the decoded train video image; a data processing module used for decoding the video images of the train, modifying the resolution and encoding the superimposed video images; a data caching module used for caching the video image data; and a remote calling module remotely calling the video image data. According to the invention, the basic state data of the train and the video image data are combined for application, thereby achieving the control of the overall state of thetrain, and improving the real-time monitoring capability of the train.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and relates to rail transit video surveillance technology, in particular to a train streaming media transmission device and a video surveillance system. Background technique [0002] In the development of rail transit, whether it is high-speed rail, subway or other rail trains, video surveillance is an indispensable part, and it is the most intuitive representation of the vehicle status. [0003] In the rail transit industry, video monitoring has been relatively mature, but the current status is that only the relevant staff of the control center (OCC) can view the video monitoring of most urban rail vehicles on the main line in real time, and the depot maintenance center ( Abbreviation: DCC) The relevant staff can only download the video data for viewing after the vehicle returns to the warehouse. When a vehicle breaks down on the main line, the DCC inspection cannot monitor the status of t...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at the above-mentioned problems in the existing rail transit vehicle video monitoring process that when the vehicle is faulty, maintenance workers cannot visually monitor the vehicle state, which leads to long troubleshooting time, etc., and provides a train streaming media transmission device and a video monitoring system, which can control the train’s The perfect combination of real-time status information and real-time video information facilitates relevant DCC staff to control the overall status of the train and enhances the real-time monitoring capability of the train
