Da Zhun Railway Train Dispatching Command System Information Sharing Platform Design And Implementation

In terms of railway informationization,the pace of quasi railway company constantly advancing and rapid development.Over the years,big quasi railway company according to the actual needs of the business,back and forth all kinds of business application system were introduced.Two large information system construction,scattered self-discipline scheduling system(CTC)and railway transportation management information system(TMIS).However,these two systems is relatively independent information systems of railway transportation,and between the transportation scheduling command center dispatcher station at all levels and dispatcher station between the station and there are cross section function,and the data exchange between each independent system is rely on manual or interface way,this means that decisions on sharing information is not full,timely,throughout has yet to eliminate the"information island" problem,not truly intelligent.For system maintenance personnel,also has brought the very big workload.Both for the user,and system operations managers have failed to really realize the burden,reduce labor intensity.Therefore,we should establish an information sharing platform,which ensures the normal functions of existing systems,to implement TMIS system and sharing of TDCS system applications.Will dispatch personnel from the traditional "a pen and a piece of paper and a ruler" working condition,realize the automatically generated according to the day shift plan stage plan,if the day shift plan changed at the same time,you can dynamically adjust the implementation of the command and dispatch work at any time.Paper information sharing platform for domestic and foreign railway train dispatching command system implementation and the status quo of railway corporation informatization,demand was analyzed,and put forward railroad train dispatching command system set up the necessity of information sharing platform.Through the system demand analysis,presents the design goal of the platform,information acquisition and processing,and follow the principle of design.On the basis of these,detailed describes the overall structure of the platform,network,database and safety design content.In the network design introduced how to build to configure the network.In database design,introduced this system USES the Oracle 10 g database and the client environment,method of data exchange,data processing,table structure,database established TMIS,DMIS user and client,the database interface configuration,etc.In the safety design content is divided into two aspects of operation environment and network security are expounded.In the realization of the system,the construction of the first described the system environment,secondly introduces interface after the system implementation,and finally tells the story of the function of the system realization in detail.A feasibility of the system,all need through a series of test verification,to prove the success of system design.In this paper,the test systems used in the black box testing,through tests verify this system can realize the expected function.Convenient for system users to better use of this system,analyze its failure often happen,and give its fault solution.This thesis summarizes the end of the article and prospect on the system.
