Method and guiding device for diesel traction engine optimizing operation

Abstract

The invention discloses an operation optimization method and an instruction device of an internal-combustion traction locomotive. The device adopts RS-485 serial communication mode to collect the train running information of current time, combines the static storage information in basic databases, adopts the operation optimization method of the internal-combustion traction locomotive with the cores of the real-time control algorithm for train running with energy saving. Namely by designing the real-time control algorithm based on combining the methods including the preliminary judgment on the operation condition of the locomotive and the handle position by the parameters including balance slope and target velocity, the expert control principle, the forward calculation of train operation and the calculation meeting the duration, the invention calculates on -line the guide proposal of the train operation optimization based on the current running environment and condition, real-time displays the operating guidance curve of velocity versus distance and the operating guidance curve of traction speed versus distance for the frontward 5 kilometers of the train running. The system can ensure that the train restores to run on schedule and runs in energy conservation via the dynamic adjustment on operation strategy or target velocity.
