WLAN technique based rail train real-time video monitoring system

Abstract

The invention discloses railway train real time video monitoring controlling system based on WLAN technique. It includes video collecting subsystem used to collect the video, wireless transmission subsystem used to transmit video flow to data receiving processor by wireless access device, monitoring controlling subsystem used to distribute the data flow to each monitoring controlling client-side by over flow media server. Compared with other movable video monitoring controlling device, the invention has clearer image, stronger controllability, can store video-record on train and monitoring controlling center at the same time to convenient for examination. In addition, it can be used in remoter video monitoring controlling for high speed railway train.

Description

Technical field

[0001] The invention relates to a real-time video monitoring system for rail trains, in particular to a real-time video monitoring system for rail trains based on WLAN technology. Background technique

[0002] High-speed rail transportation (underground railway, elevated light rail, single-track transportation, etc.) has become one of the main directions of future urban transportation development due to its fast and convenient advantages.

[0003] In order to realize the wireless transmission of the video information of the real-time status in the rail train, there are usually two realization methods:

[0004] The first is to use a special microwave channel to transmit analog video signals. This implementation method requires the construction of a special microwave relay station to achieve effective coverage of microwave signals. The initial infrastructure and later maintenance investment is large, although the image quality can be guaranteed. However, the cost of...

Examples

Embodiment Construction

[0061] The following takes a light rail train as an example to specifically describe the implementation of the present invention.

[0062] The invention combines the wired local area network and the wireless local area network flexibly, and realizes the monitoring and management of the high-definition image on the mobile carrier.

[0064] 1. Video capture subsystem (100)

[0065] As shown in the upper part of Figure 1, the video acquisition subsystem (100) forms a wired local area network, including a camera (110), a video encoder (120), a switch (130) on the vehicle, a data acquisition server (140), and a monitoring client on the vehicle ( 150);

[0066] The camera (110), the video encoder (120), and the on-board switch (130) are connected in sequence; the on-board switch (130) is respectively connected with the data collection server (140) and the on-board monitoring client (150).
