Jumper connection looped network system applicable to rail transit vehicle

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.
