Vehicle-mounted monitoring system with scatter storage function

Abstract

The invention discloses a vehicle-mounted monitoring system with a scatter storage function, which is characterized by comprising two video servers, a media gateway, an LCD (Liquid Crystal Display) touch screen display, a 360-degree full-view camera, a semi-spherical infrared camera, a network cable, a video cable and a power cable; the 360-degree full-view camera and the semi-spherical infrared camera collect analog video signals; the media gateway carries out analog to digital conversion on the received analog video signals, compress the converted analog video signals, and store the compressed digital video signals to the hard disk of a local media gateway; meanwhile, the digital video signals are simultaneously transmitted to video storages of driver cabs of a head train and a trailer for storage through a 1000M annular redundant Ethernet formed of the network cable and are displayed on the LCD touch screen display to form a video file three-layer scatter storage mechanism. Throughthe vehicle-mounted monitoring system with the scatter storage function, video images in a railway carriage, which are collected by the camera, can be simultaneously stored and monitored in real timeand video data can be stored in three layers.

Description

technical field [0001] The invention relates to a video monitoring system, in particular to a vehicle-mounted video monitoring system with a decentralized storage function. Background technique [0002] Rail transit has become the main choice for people to travel because of its fast speed, punctuality, convenient travel, and not being affected by bad weather. However, due to the dense flow of people and the wide influence and radiation of rail transit, it is very easy to become the main target of terrorist attacks. Once this danger occurs, it will cause heavy casualties and interruption of traffic arteries, causing panic in the society. Such as the Daegu subway incident in South Korea on February 18, 2003 and the London subway explosion in England on July 7, 2005. [0003] With the increasingly intensive use of rail transit as a means of transportation by the public and in view of the above-mentioned public safety situation, the needs related to platform management, vehicle...

Problems solved by technology

[0004] Since the monitoring devices on the train currently use 100M wired Ethernet networking, when the network cable passes through the coupler between the carriages, the physical medium is disconnected, and the network bandwidth is severely attenuated. The actual effective bandwidth does not exceed 40M, which cannot support the entire network. Simultaneous transmission of train video images to the driver's cab of the head and tail trains, so the transmission and storage of video data can only be realized in a short time and a small number of video inputs

At the same time, when the train compartment is damaged or the intermediate network is disconnected, the security and integrity of the stored video data cannot be guaranteed, and the monitoring system device is not compatible with the complex electromagnetic environment and vibration environment on the train, and the video data cannot be guaranteed. storage integrity
