Embodiment approach

[0078] Embodiments of the present invention are described in detail as follows in conjunction with the accompanying drawings:

[0079] When the main engine of the diesel traction locomotive optimal manipulation guidance device is powered on, it will automatically start to enter the human-computer interaction interface of the diesel traction locomotive optimal manipulation guidance system, as shown in Figure 4. The system automatically opens the serial port communication unit, and dynamically reads information such as train speed, position, locomotive working condition, diesel engine speed, train pipe pressure, signal signal ahead, and train marshalling every 50 milliseconds and displays them on the human-computer interface.

[0080] This system has a relatively complete and expandable basic database system. The basic database includes two parts: one is the line database, which is used to input data information related to the line: including line vertical section, signal equipme...

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.

Description

technical field [0001] The invention relates to a method and a guiding device for optimal manipulation of an internal combustion traction locomotive, belonging to the field of locomotive control. Background technique [0002] The train operation process is a typical complex, multi-input, multi-objective, large-delay nonlinear system, full of a large number of random and uncertain factors, it is difficult to find its precise mathematical model and optimal solution, how to accurately, Quickly calculate the operation effect of the train under various conditions, and search for a satisfactory solution to realize the safe, stable, punctual and energy-saving operation of the train is the main task of the optimal operation calculation of the train. [0003] Due to the complexity of the train operating environment, the algorithm model of optimal train operation and its solution technology is a very difficult task, and has a strict application range. There have been some researches o...
