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 method for selecting and controlling pantographs for reconnecting four-marshalling intercity EMUs is characterized by comprising 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 configured to receive a pantograph control command through the multi-function vehicle bus, where the pantograph control command includes a bow raising or lowering command; the pantograph control command is passed through a twisted wire The train bus is sent to the central control unit of the slave control car;

[0024] S103, the master control vehicle and the slave control vehicle perform preliminary selection of the pantograph according to the command of raising the bow, according to the pantograph selection strategy during the non-reconnection operation of the EMU, and according to the principle of prioriti...

Abstract

A pantograph selection control method for a double-connected four-car intercity EMU, which is characterized in that: the master control EMU and the slave control EMU respectively preliminarily determine the pantograph selection strategy used in non-duplex operation. Pantograph, the central control unit of the two EMUs determines the final selection result of the pantograph according to the reconnection method and the preliminary pantograph selection result, so as to avoid the two adjacent EMUs from raising two adjacent Pantograph conditions, and try to ensure that the pantographs used by the two EMUs are all front bows or both are rear bows, so as to reduce the pair of slave control EMUs due to the short distance between the two pantographs used Risk of adverse effects from the pantograph.

Description

technical field [0001] The invention relates to a pantograph control technology for rail vehicles, in particular to a pantograph selection control method for a reconnected four-car marshalling EMU. 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 operate the reconnected intercity EMUs. Therefore, how to make the optimal control strategy for the reconnected intercity EMUs is the main issue. Research priorities for those skilled in the field. [0003] The operation of the four-car marshalling intercity EMU needs to obtain electrical energy through the contact between the pantograph on the top and the catenary wire, and each EMU has two pantographs. When the four-car marshalling intercity EMU is in non-reconnected operation, the pantograph that is farther away from the driver's cab at the occupied end will be raised first; when the pantogr...
