Embodiment 1

[0032] like figure 2 , 3 As shown, the present embodiment is used to realize the device of the reconnection control circuit for wireless reconnection of locomotives, including a reconnection control circuit 1 for controlling the transmission of reconnection control signals, and the reconnection control circuit 1 is provided with an electric key interlock switch 570QS and The reconnection isolating switch 592QS is used to control the reconnection intermediate relay. The reconnection isolating switch 592QS is a switch unit with the function of receiving the electric key signal and enabling the reconnection intermediate relay to be powered on at the same time.

[0033] In this embodiment, on the basis of the original structure of the reconnection control circuit of the original line reconnection locomotive, the reconnection isolating switch with the function of accessing the electric key signal and enabling the reconnection intermediate relay to be powered on at the same time el...

Embodiment 2

[0039] like Figure 4 , 5 As shown, the present embodiment is used to realize the device of the reconnection control circuit for wireless reconnection of locomotives, including a reconnection control circuit 1 for controlling and transmitting a reconnection control signal, and the reconnection control circuit 1 is provided with an electric key interlock switch and a In order to control the reconnection isolation switch of the reconnection intermediate relay, the reconnection control circuit 1 is also provided with a synchronous control module 2, which is connected to the reconnection isolation switch, and the synchronization control module controls when the reconnection isolation switch is closed. The key signal, and at the same time make the reconnection intermediate relay energized to start. That is, the difference between this embodiment and Embodiment 1 is that the connection mode of the original reconnection isolating switch is not changed, and the synchronous control mo...

Abstract

The invention discloses a double heading control circuit device and method for implementing locomotive wireless double heading. The device comprises a double heading control circuit, wherein the double heading control circuit is provided with an electricity key interlock switch and a double heading isolating switch for controlling a double heading intermediate relay; and the double heading isolating switch is a switching unit having a function that the double heading intermediate relay is electrified to start when an electricity key signal is input. The method comprises the following steps: 1) acquiring double heading switching signals in advance by locomotives, judging whether preset conditions are satisfied, and starting the locomotives to perform wireless double heading grouping if so; and 2) in the normal operation process of the locomotives adopting wireless double heading, monitoring the state of the double heading isolating switch in real time by means of the wireless double heading control device, transmitting locomotive control signals in a wireless manner, disconnecting the double heading isolating switch, and then executing a single-unit operation mode. The device and method disclosed by the invention have the advantages of simple operation control, low required cost, no need to change the original double heading control structure and high control reliability.

Description

technical field [0001] The invention relates to the technical field of electric locomotive control, in particular to a device and method for a reconnection control circuit for realizing wireless reconnection of locomotives. Background technique [0002] In order to meet the demand of heavy-haul freight railway traffic, heavy-duty freight trains generally run in the way of locomotive reconnection, and multiple locomotives are reconnected to increase the traction and braking force of the train, thereby increasing the cargo capacity of the train. At present, electric locomotives usually use wired reconnection, that is, multiple locomotives are connected through reconnection cables, and the reconnection control signals of the locomotives are transmitted through reconnection cables. [0003] Take the Shaoshan 4B type locomotive as an example, each locomotive consists of two locomotives A and B, and each locomotive is equipped with a set of four reconnection intermediate relays, w...
