Problems solved by technology

[0005] In this case, when the synchronous braking control scheme is adopted for heavy-duty combined trains, the couplers between the vehicles will be excessively backlogged or pulled up excessively, and when the safety range of the couplers is exceeded, it is easy to cause accidents such as derailment and broken couplers
[0006] Therefore, the traditional synchronous braking control scheme can no longer meet the needs of heavy-duty combined trains.

Embodiment 1

[0079] see figure 1 , The present invention provides a first embodiment of a heavy-duty combined train, including a master locomotive and a slave locomotive. The master locomotive is mounted with multiple vehicles (only two vehicles are used as an example in the figure), and the slave control locomotive is mounted with multiple vehicles (only two vehicles are used as an example in the figure).

[0080] The master locomotive is connected to the vehicle by a coupler, the vehicle is connected by a coupler, and the slave locomotive is connected to the vehicle by a coupler.

[0081] Both the master locomotive and the slave locomotive include: network control system and monitoring equipment (LKJ for short) connected to the network control system, traction system, braking system and wireless reconnection control system. Among them, the master locomotive and the slave locomotive can perform communication connection through the wireless reconnection control system.

[0082] see fig...

Embodiment 2

[0127] Embodiment 2 is similar to the steps in Embodiment 1. In Embodiment 2, for step S202, the master locomotive calculates the distance between the master locomotive and the slave locomotive based on the current master position and the current slave position. The vehicle coupler status provides another implementation method:

[0128] In this embodiment, it is not necessary to consider that the current actual distance S is between the preset minimum distance L 压 and preset maximum distance L 拉 The size relationship between the master locomotive and the slave locomotive can be directly calculated, and the pull ratio is determined as the coupler deformation state between the master locomotive and the slave locomotive .

[0129] The calculation formula of the pull-up ratio y can be: y=(S-L 压 ) / (N*G), 0≤y≤1.

[0130] In the second embodiment, another implementation is provided for step S204 to generate asynchronous first control commands and second control commands for the mas...

Abstract

The invention provides a heavy-load combined train asynchronous control method and a related device. The method comprises the following steps: acquiring a current master control position of a master control locomotive and a current slave control position of a slave control locomotive; calculating a vehicle coupler state between the master control locomotive and the slave control locomotive based on the current master control position and the current slave control position; determining the working condition state of the heavy-load combined train; based on the working condition state and the coupler deformation state, generating a first asynchronous control instruction and a second asynchronous control instruction for the master control locomotive and the slave control locomotive respectively; and enabling the master control locomotive to execute the first control instruction, and sending the second control instruction to the slave control locomotive to enable the slave control locomotive to execute the second control instruction so as to maintain or reduce the coupler deformation between the master control locomotive and the slave control locomotive. According to the invention, asynchronous control between the master control locomotive and the slave control locomotive can be realized, and safe and stable operation of the heavy-load combined train is ensured.

Description

technical field [0001] The present application relates to the technical field of rail transit, in particular to an asynchronous control method for a heavy-duty combined train and related devices. Background technique [0002] my country's heavy-duty combined trains have a load of 10,000 tons, 20,000 tons and above. In order to carry more weight, heavy-duty combined trains usually include multiple vehicles. At least one slave locomotive, coupler links are used between multiple vehicles; the master locomotive and the slave locomotive respectively control some vehicles, thereby improving the smooth and high-speed operation of the heavy-duty combined train. [0003] At present, heavy-duty combined trains mainly run on the Daqin Line. The heavy-duty combined train adopts a synchronous braking control scheme, that is, no matter what track environment the heavy-duty combined train is in, the master locomotive and the slave locomotive adopt consistent braking. command to perform bra...
