Six-axle new energy rail locomotive transmission system and transmission control method

Abstract

The invention relates to the technical field of new energy rail locomotives, in particular to a six-axle new energy rail locomotive transmission system and a transmission control method.The six-axle new energy rail locomotive transmission system comprises the steps that starting instructions are sent to motor drivers of six axle transmission units according to initial set parameters and locomotive state information, and a new energy power source is controlled to output energy to a power conversion device; data of a torque sensor, a speed sensor, a track inclination sensor and a wind speed sensor are collected and updated at a preset frequency, a dynamic data flow is formed, real-time torque values and rotating speed values of all axles are calculated, a power distribution scheme is calculated through comparative analysis, and output parameter adjusting instructions are sent to all motor drivers. Therefore, the power output of each axle is adjusted. The six axle transmission units are precisely and cooperatively controlled by the central controller, so that optimized power distribution among multiple axles is realized, the running stability and stability of the locomotive are effectively improved, and the abnormal wear of wheels is reduced.
