A real-time optimal control system for automatic operation of freight locomotives based on dispatch signals

Abstract

The invention relates to a freight locomotive automatic-control real-time optimization control system based on a dispatch signal, and belongs to on-board devices of freight locomotives. The freight locomotive automatic-control real-time optimization control system comprises a man-machine interaction display interface freight locomotive automatic-control real-time optimization controller and a manual / automatic conversion communication device. The system can acquire line information and other established information and current locomotive speed and other real-time information, wherein all the information is required by automatic-control real-time optimization control. As the operation of a locomotive is concretely controlled through a driver controller communication device and a locomotive control execution device, a driver can conveniently perform manual / automatic driving switching through the man-machine interaction display interface and a driver control console panel in actual driving. According to the freight locomotive automatic-control real-time optimization control system, a locomotive optimization operation curve can be compensated and adjusted in real time according to the temporary dispatch signal to obtain the current optimization target curve; besides, a locomotive control gear sequence is controlled to be output in a self-adapting mode in real time according to the current optimization target curve and the current operation state information.

Description

technical field [0001] The invention relates to a real-time optimal control system for automatic manipulation of freight locomotives based on dispatching signals, and belongs to the technical field of locomotive and vehicle control. Background technique [0002] With the research of experts and scholars from various countries on locomotive energy-saving control optimization system, in view of the many advantages of locomotive active energy-saving control optimization, developed countries in the world are vigorously promoting the popularization and application of locomotive energy-saving optimization control system. General Electric Company of the United States has successfully developed the train operation optimization system TripOptimizer, and applied for a patent for "system and method for train formation optimization" (application number 200780000072.4), which can optimize fuel consumption based on the composition and driving routes of different locomotives, In order to m...
