A reconnection train set and its reconnection communication system

Abstract

The invention discloses a double heading communication system of a double heading train set. The system comprises a double heading communication device which is used for collecting state information of a current train and converting the state information into carrier signals, and a hard-wired cable which is connected with the double heading communication device and is used for transmitting the carrier signals to other trains. According to the double heading communication system disclosed by the invention, a locomotive hard-wired double heading line is reused by the hard-wired cable, so it is unnecessary to set up a special cable channel additionally, production and maintenance costs are greatly reduced, and a utilization rate of line resources is improved. According to the double heading communication device, the hard-wired cable is taken as a physical layer dielectric carrier, the state information of the current train is sent to the other trains in a power carrier communication mode, and the whole double heading train set is enabled to realize internal intercommunication. According to the power carrier communication mode, the communication speed is fast, the data transmission volume is high, and the complicated communication demands of the double heading train set can be satisfied. The invention also discloses a double heading train set comprising the double heading communication system. The double heading train set has the advantages as mentioned above.

Description

technical field [0001] The invention relates to the field of rail vehicles and communication technologies, in particular to a reconnection communication system for reconnection train sets. The present invention also relates to a reconnection train set comprising the above reconnection communication system. Background technique [0002] With the development of China's machinery industry, more and more machinery and equipment have been widely used. [0003] The vehicle industry is the backbone of the machinery industry and can generally be divided into locomotive and automobile industries. Among them, there are many types of locomotives, including passenger and freight trains, bullet trains, high-speed rail, subway, light rail, etc. The locomotive has a large carrying capacity, high speed and good safety, so it is often used as the main way of long-distance transportation. [0004] In the electric traction operation of the main railway line, one locomotive traction sometime...

Problems solved by technology

However, because the equipment and network lines are dedicated to the dedicated network, the production cost is relatively high

At the same time, in order to improve the operational reliability of reconnected vehicles, other communication methods and lines are usually added, further increasing production and maintenance costs
