Study Of The Computer Mechod On Train Transit Diagram

The train diagram is an integrated plan of railway transportation, and is the base of railway organization work. Train diagram computerization is an important measure for marketing railway transportation. Through continuous efforts by the railway managers and R&D staff from major institutions, we have made major progress in computer based train diagramming. Most of the railway bureaus have been applying it. Train diagram is replacing gradually the old ways of train traffic control, which relies mainly on one diagram, one pen, one triangular rule and one ruler via telephone communications. In general, the computer based diagram system has satisfied the requirements of diagramming, there is still a lot more research on this issue to be done.This article will mainly explain the computer-based system for train diagram from two aspects: 1. The design and realization of the database for train diagram 2. Using OOP programming to finish the train diagram designThe main research contents are as follows:1 .This article will explain in detail in terms of the structure of CTC (Centralized Traffic Control) system and the theories behind it.2.The structure design has been underway to the train diagram database on the basis of relationship database rules. And the concrete implementation scheme of Train Diagram distributed database has been analyzed and designed, including its security, transaction management, ODBC and Pro*c data access technology.3.This article will also discuss the drawing of the train diagram by using OOP programming, it also analyzed the issue of initializing the diagram data. At the same time, it gives out the corresponding solutions to the problems during the design of the diagram.
