Design And Implementation Of Train Traction Calculation System

Train traction calculation is based on mechanics, scientific experiments and advanced manipulation experience, analysis various phenomena and principle in the course of train operation and it is used to solve some technical and technical economic problems in operation and design.Current train traction calculation software calculates with manual simulated train driver operating. It has lower degree of automation and it is not suitable for desing and research units for use, which are lack of practical manipulation experience. Exploiting a train traction calculation software which has a higher degree of automation can improve the work efficiency, which has good practical significance.Based on the train traction calculation theory and the analysis of current softwares, the acticle designs a new train traction calculation system. The main content of this acticle are followings:1,It makes detailed needs analysis for the system. According to the traction workflow, it designs the system's overall structure and makes detailed function design for data management, computing and HCI modules. It complets the conceptual design and logic design of the system database by using database design theory.2,By using VC++, it realizes most system functions, including interface, read,save,add,delete and modify operations of basic data, data format conversion, pretreatment of basic data before calculation, setting control data. At the same time it uses Windows graphics technology to achieve the simulation of line cross-section and train running and graphics printing.3,It analyzes how operating conditions impact running. With timesaving mode and outstanding control experience, it determines the basic principles of working status options and conversion and studies automatic calculate method under a given condition. It makes the automatic calculation control process by dynamic grouping basi control strategy. It compiles procedures to realize the automatic calculation function.4,Using automatic calculation function, it calculates the running time and energy consumption of sample line and demonstrates the effectiveness, accuracy and relevance of the system by comparing other system's results.
