Shunting locomotive control method and shunting locomotive

Abstract

Embodiments of the invention provide a shunting locomotive control method and a shunting locomotive. The method comprises the following steps: acquiring the working state of the shunting locomotive, wherein the working state is specifically one selected from a group consisting of a waiting-for-working state, a light locomotive running state and a shunting state; if the working state is the waiting-for-working state or the light locomotive running state, controlling the shunting locomotive to enter the mode of power supply via a power battery, wherein in the mode of power supply via the power battery, the power battery supplies power to the shunting locomotive; and if the working state is the shunting state, controlling the shunting locomotive to enter the mode of power supply via a dieselengine, wherein in the mode of power supply via the diesel engine, the diesel engine supplies power to the shunting locomotive. Therefore, the method overcomes the problem of large current supply lossof the diesel engine when the shunting locomotive is in the waiting-for-working state and the light locomotive running state, solves the problem that the power battery has large capacity and large size, and reduces requirements on the diesel engine.

Description

technical field [0001] The invention relates to automatic control technology, in particular to a shunting locomotive control method and the shunting locomotive. Background technique [0002] Shunting locomotives refer to locomotives used for shunting operations such as train marshalling, disintegration, line transfer, and vehicle pickup and delivery. running status. [0003] When the traditional diesel shunting locomotive is waiting for work or running alone, the entire diesel unit is kept running to provide electricity for the diesel locomotive. At this time, insufficient diesel combustion causes carbon deposits, and the efficiency of the diesel engine is low. Most of the energy is consumed in the diesel engine. On its own mechanical loss and generator efficiency loss. The hybrid electric locomotive provided by the prior art solves the problem of high fuel consumption when the locomotive is waiting for work or running alone. Among them, hybrid locomotives include diesel ...
