Problems solved by technology

[0003] At present, among the high-speed EMUs introduced in China, most of the EMUs that realize the reconnection of two trains adopt network control methods. Due to certain limitations in network transmission signals and distances, when the network fails, the reconnection trains cannot operate normally.

Embodiment Construction

[0017] Such as figure 1 As shown, it is a schematic diagram of the electrical connection of the butt joint of two EMUs. Each EMU has two front and rear locomotives, so there are 4 locomotives drawn in the figure, which are respectively A car, B car, C car, and D car. In this embodiment , the A car of the left EMU is to activate the driver's cab, and the A car is taken as an example below (other locomotive circuit structures are the same) to illustrate the multi-train electrical reconnection control circuit of the EMU in the present invention.

[0018] Such as figure 1 , figure 2 As shown in , the electrical reconnection control circuit for multiple trains of the EMU (take A train as an example), including: the electrical connection relay 5, the activation relay (not shown in the figure) located in the cab, and the first train line running through the train L1a, the second train line L2a, it also includes the reversing completion relay 10 arranged in the cab, the electrical ...

Abstract

The invention relates to a multi-train electrical reconnection control circuit for a motor train unit and a reconnection method. The control circuit comprises a mechanical connection relay, a mechanical car coupler travel switch, an electrical car coupler, an electrical connection relay, an activation relay in a cab and a reversing finishing relay, wherein the extension of a loop train line can be finished mainly through the electrical connection relay and the activation relay. By virtue of the relay control circuit with simple principle, the aim of meeting the requirement on flexible marshalling of the motor train unit is achieved in a simplest realization way. Not only is simplicity in operation improved, but also the reliability of the system is improved. The multi-train reconnection of the motor train unit is suitable for flexible regulation on the marshalling to improve the transport capacity when the passenger flow is large, is suitable for an intercity motor train unit and a small marshaled motor train unit and has wide future application prospect.

Description

technical field [0001] The invention relates to multiple train reconnection technology of multiple trains, in particular to a multiple train electrical reconnection control circuit and reconnection method of multiple trains. Background technique [0002] The multi-train reconnection technology of EMUs requires simplicity, reliability and practicability in the design. After the multi-train reconnection of EMUs is realized, the electrical subsystems, such as driving, traction, braking, door control, lighting, PIS, TCMS Wait for automatic expansion to complete. [0003] At present, among the high-speed EMUs introduced in China, most of the EMUs that realize the reconnection of two trains adopt network control methods. Due to certain limitations in network transmission signals and distances, when the network fails, the reconnection trains cannot operate normally. . In terms of urban rail subways, train reconnection is only carried out in rescue situations, and only the braking...
