Embodiment Construction

[0023] 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.

[0024] see figure 1 . The speed signals and current signals of the 6 traction motors of the locomotive are detected by the peripheral signal device SCM, and sent to the high-speed input device HSI and A / D converter of the CPU respectively.

[0025] see figure 2 The speed subroutine flow shown. Firstly enter box 2.1 and obtain the minimum ...

Abstract

The invention discloses an anti-slip control method of a locomotive, comprising the following steps: processing fluctuation of a rotation speed signal, judging out a true value of rotation and an average current value of a motor, if the rotation speed of a traction motor is simultaneously more than a rotation speed set value and less than a current set value, judging that the traction motor is ina slip state, reducing output power of a main generator once in each 30ms under traction working condition or reducing exciting current of the traction motor under braking working condition, and simultaneously, sanding. When locomotive adhesion is recovered, recovering the output power of the main generator or the exciting current of the traction motor. The control method is timely and accurate in response, quick in adhesion recovery and small in change of a whole system.

Description

technical field [0001] The invention relates to locomotive control technology, in particular to a locomotive anti-idling sliding control method. Background technique [0002] Diesel locomotives under the influence of bad weather such as mountainous lines, rain and snow, will deteriorate the adhesion between the track and the wheels, and easily cause idling and sliding. Idling and sliding in the large ramp section will cause the train speed to drop sharply in a short time. When it is serious, due to the failure of stopping and starting, it will also cause multiple trains to be out of service and delayed for a long time. [0003] The adhesion between the wheel and the rail which affects the traction and braking force of the locomotive is always limited. In unfavorable conditions such as poor road conditions, large slopes, and small curve radii, once the traction force and braking force generated by the traction motor exceed the wheel If there is no adhesion between the rails...
