Research And Implementation Of Metro Vehicle Base Plan Compilation System

The urban rail transit vehicle base is a place for parking,inspection,maintenance,cleaning and operation management of urban rail transit vehicles.The main service target of the vehicle base is trains.The trains depart from the vehicle base and enter the main line to implement operational tasks every day.The trains travel from the vehicle base to the main line every day to perform operational tasks,and return to the base after the end of the operational mission.The vehicle base collection and departure operations are carried out on the basis of the completion of the plans.At present,the vehicle operation plan of the vehicle base is compiled by the compiler according to the train diagram,the maintenance plan,and the parking conditions of the yard line.The preparation method is manual preparation,and the compilation complexity is high and the efficiency is low.This thesis focuses on the compilation of the departure plan and the collection plan,and develops an operation planning system that can realize the rapid compilation of the plan and the simulation verification of the plan.The main research results of this thesis include:Firstly,this thesis introduces the general situation and the train organization status of the vehicle base.Then the system is designed from software architecture,function,system interface and database based on the system requirements analysis.The automatic compiling problem is mathematically analyzed when designing the automatic compiling function.Building a departure model with objective function of decreasing each train traveled distance and building a collection model with objective function of maximizing the train returning efficiency.The algorithm is designed to realize the automatic compilation of the plan in the implementation of the system.Finally,the C# programming language is used to develop the compilation system.The system can import the compiled data,automatically compile the departure plan,automatically compile the collection plan,manually compile the plan,simulate and verify the plan,automatically adjust the plan and export the plan report.Simulate the system with the compiled data which is processed field.The results show that the system can quickly and accurately "one-click" to compile the required departure plan and collection plan,and can assist the operator to manually compile plan.After the plan compilation is completed,the system can achieve quick verification of the plan,and can also automatically adjust the plan in the simulation.It is a fully functional,user-friendly and operability system which helps to improve the efficiency of the departure plan and the collection plan,and provides a new method for vehicle base compilation plan.
