Description

technical field

The invention relates to the technical field of locomotives, in particular to a system and method for realizing pantograph control of double-connected locomotives.

Background technique

In the electrified railway, the operation of the locomotive needs to obtain electric energy through the contact between the pantograph on its top and the catenary wire. Effectively controlling the raising or lowering of the pantograph is an important issue to ensure the safety of locomotive operation. In the prior art, there are usually two methods to control the pantograph. The first method is to use the pantograph toggle switch or transfer switch to directly control the coil power supply of the pantograph lifting solenoid valve, and directly control the On-off of the bow-raising pipeline. The second method is to set the pantograph selection switch on the locomotive to select the pantograph that is about to be raised, and trigger the command of raising or lowering the pantograph through the pantograph trigger switch to control the raising or lowering of the pantograph.

Each locomotive has two cabs, and the electric key of the locomotive determines which cab is the cab at the occupied end. Specifically, the cab that can be put into the electric key of the locomotive is the cab at the occupied end. The electric key of the locomotive is a switch to turn on the control power of the locomotive, and it is also a sign to confirm that the cab of the locomotive is put into use. Each locomotive is equipped with only one locomotive electric key, and only one locomotive electric key can be used for reconnected locomotive groups at the same time. 1 microcomputer display 1 is installed in each driver's cab, and the activation of the microcomputer display is also determined by the locomotive electric key, and the pantograph selection function of the microcomputer display can only be activated if the driver's cab is occupied.
