Embodiment approach

[0078] The implementation of the present invention will be described in detail as follows in conjunction with the drawings:

[0079] The main engine of the internal combustion traction locomotive optimization operation guidance device is powered on and automatically starts to enter the human-computer interaction interface of the internal combustion traction locomotive optimization operation guidance system, as shown in Figure 4. The system automatically turns on the serial communication unit, and dynamically reads train speed, position, locomotive operating conditions, diesel engine speed, train tube pressure, front signal signal and train marshalling information every 50 milliseconds and displays them on the human-machine 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 line-related data information: including line profile, signal equipment, milea...

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 optimized operation 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-lag 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, It is the main task of train optimization operation calculation to quickly calculate the operation effect of the train under various conditions, and search for satisfactory solutions to realize the safe, stable, punctual and energy-saving train running. [0003] Due to the complexity of the train operation environment, the algorithm model and its solution technology for optimal train operation is a very difficult task, and it has a strict application range. There have been some researches on the control ...
