Embodiment Construction

[0012] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0013] see figure 1 , the flow of the locomotive constant speed control method in this embodiment starts from box 1.1, and enters box 1.2 to detect a constant speed command. At block 1.3, the command velocity Vo is read. At box 1.4, the command traction force Fo is read. Enter box 1.5, and detect the current actual speed V of the locomotiv...

Abstract

The invention discloses a constant speed control method of a locomotive. The method comprises the following steps: reading set values of traction Fo of and velocity Vo of a constant speed instruction, detecting the actual velocity V of the locomotive, and comparing the actual velocity V with the instruction velocity Vo; if the absolute value of the difference of Vo and V is smaller than or equal to 2, making the traction F equal to the sum of Fo and 50 times the absolute value of the difference of Vo and V, or else, making the traction F equal to the sum of Fo and 150 times the absolute value of the difference of Vo and V; automatically adjusting traction and brake conditions of the locomotive according to the speed set by a driver, so that a train automatically runs according to the set velocity, and the manipulation strength of the driver and impact on the train are relieved.

Description

technical field [0001] The invention relates to a method for controlling a constant speed of a locomotive, belonging to the technical field of railway locomotives. Background technique [0002] During the operation of the locomotive, due to complex line conditions such as ramps and curves, the driver needs to adjust the increase or decrease of the speed of the locomotive by manipulating the controller handle level. The driver needs to adjust the increase or decrease of the speed of the locomotive by manipulating the level of the controller handle. Ordinary and complicated operations can easily cause fatigue to the drivers and passengers, and the range of operations is difficult to control, making them more impulsive to the vehicle. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a method for controlling the constant speed of the locomotive. [0004] The object of the pres...
