Problems solved by technology

However, if a pantograph fails and cannot be used, if two adjacent pantographs are raised, the distance between the two pantographs will be relatively close, causing the catenary wire to be damaged when the front pantograph crosses the catenary. Fluctuations, which in turn can adversely affect subsequent pantographs

Embodiment Construction

[0021] refer to figure 1 , a pantograph selection control method for double-connected four-group intercity EMUs, characterized in that it includes the following steps:

[0022] S101. The remote input / output unit of the driver's cab is used to collect the state of the pantograph toggle switch;

[0023] S102. The central control unit of the main control vehicle is used to receive a pantograph control instruction through a multi-function vehicle bus, and the pantograph control instruction includes a pantograph raising or lowering instruction; transmit the pantograph control instruction through a stranded wire sent to the central control unit of the slave control car via the train bus;

[0024] S103, the master control car and the slave control car perform a preliminary selection of pantographs according to the pantograph selection strategy when the EMU is not reconnected according to the bow-raising command, and according to the principle of preferentially selecting the rear bow...

Abstract

The invention discloses a reconnection four-in-one-group intercity D-series high-speed train pantograph selection control method. The method is characterized in that a master-control D-series high-speed train and a slave-control D-series high-speed train preliminarily determine pantographs used respectively according to a pantograph selection strategy during non-reconnection running, and central control units of the two D-series high-speed trains determine a final pantograph selection result according to reconnection mode and a preliminary pantograph selection result to avoid the circumstancethat two D-series high-speed trains rise two adjacent pantographs in different reconnection modes as much as possible and ensure pantographs used by the two D-series high-speed trains to be front arches or rear arches as much as possible so as to lower risk of unfavorable impact on slave-control train pantograph due to the fact that two used pantographs are close to each other.

Description

technical field [0001] The invention relates to a rail vehicle pantograph control technology, in particular to a pantograph selection control method for a double-connected four-car train set. Background technique [0002] In the busy intercity railway transportation organization, in order to meet the needs of sending passengers, especially in the peak period, it is necessary to run double-connected intercity EMUs. Therefore, how to make an optimal control strategy for double-connected intercity EMUs is a basic The focus of research for those skilled in the field. [0003] The operation of the four intercity EMUs needs to obtain electric energy through the contact between the pantograph on the top and the catenary wire, and each EMU has two pantographs. When the four intercity EMUs are running in non-duplex mode, the pantograph that is farther away from the driver's cab at the occupying end will be raised first; when the pantograph is unavailable, the pantograph that is clos...
