A shunting control method, device and system for an electric locomotive

Abstract

The invention discloses an electric locomotive shunting control method, which is used for realizing shunting control of an electric locomotive. The method comprises the steps that: a shunting control mode is activated after a shunting control activating command sent by an intelligent display unit is received; an auxiliary contact signal acquired by an input-output unit of a cab is received, and the state of the locomotive is determined according to the auxiliary contact signal; a maximum traction value / a maximum brake value is obtained, a voltage output signal acquired by the input-output unit of the cab is received, and a traction force request value / a braking force request value is obtained according to the maximum traction value / the maximum brake value and the voltage output signal; a traction force value / a braking force value of the locomotive in shunting is obtained according to the traction force request value / the braking force request value; and the traction force value / the braking force value is sent to a traction control unit, so that a needed traction moment / braking moment is provided for the locomotive by the traction control unit according to the traction force value / the braking force value. The invention also discloses an electric locomotive shunting control system and device.

Description

technical field [0001] The invention relates to the railway industry, in particular to a shunting control method, device and system for electric locomotives. Background technique [0002] In the production process of railway transportation, except for the arrival, departure, passage and operation of the train at the station, all purposeful movement of rolling stock is collectively called shunting. In the prior art, the shunting control method is that the locomotive control system calculates the traction force and electric braking force of the locomotive according to the traction / braking curve of the locomotive according to the actual position of the traction brake handle of the driver controller. Because the load of the locomotive is much lower than that in normal operation during the shunting process of the locomotive, the traction power required by the locomotive is very small at this time. Therefore, the driver controller mainly changes in the traction area close to the ...
