Embodiment

[0025] Such as figure 1 As shown, a jumper ring network system suitable for rail transit vehicles includes a front control terminal A, six car data acquisition and storage devices 2 and a rear control terminal B. The front control terminals pass through odd numbers in ascending order. After the data collection and storage device of the serial number car is connected to the rear control terminal, the rear control terminal is connected to the front control terminal after passing through the data collection and storage device of the even numbered car in descending order, that is, the front control terminal A→car 1→car 3→car 5→rear control terminal B→car 6→car 4→car 2→front control terminal A.

[0026] The front control terminal A and the rear control terminal B both include a control host 11 connected to each other and an integrated power supply 12 with a communication function. 2, the integrated power supply 12 of the control terminal B at the rear of the car is connected to th...

Abstract

The invention relates to a jumper connection looped network system applicable to a rail transit vehicle. The jumper connection looped network system comprises a vehicle head control terminal, at least four carriage data acquisition and storage devices and a vehicle rear control terminal, wherein the vehicle head control terminal is connected with the vehicle rear control terminal after passing through odd number carriage data acquisition and storage devices in sequence according to an ascending order, and the vehicle rear control terminal is connected with the vehicle head control terminal after passing through even number carriage data acquisition and storage devices in sequence according to a descending order. Compared with the prior art, the jumper connection looped network system applicable to the rail transit vehicle has the advantages of being good in extension performance, safety, and reliability, and convenient to maintain and manage, and low in implementation cost.

Description

technical field [0001] The invention relates to a rail transit vehicle monitoring technology, in particular to a jumper ring network system suitable for rail transit vehicles. Background technique [0002] The video monitoring system of rail transit vehicles needs to build a communication network on the train to transmit control commands and video data. Therefore, the design of the communication network must not only meet the characteristics of train vehicles, but also meet the technical requirements of the video surveillance system itself. [0003] Today, the high-definition and digital development of video acquisition equipment and network storage equipment in video surveillance systems has greatly increased the system's requirements for the bearer network. The existing train communication network is a train control and diagnosis information data communication network. Although the communication network adapts to the harsh environment of the train and has good reliabilit...
