Research On Data Information Platform Of Intelligent Train Dispatching Command System

Transportation is an important part of the national economy and a means to ensure people’s contact in all aspects of daily life.As an important national infrastructure,railway plays an indispensable role in people’s life.The rapid development of China’s economy has put forward higher demands on China’s railway transportation.Railway transportation operation scheduling is the core part of railway transportation organization.At present,the existing railway transportation information system is relatively independent,the preparation of operation plans is relatively scattered,and the accuracy of train operation plans is poor.With the improvement and maturity of modern technologies such as Internet information technology,big data and cloud computing,the traditional mode of railway transportation information management system has been broken and has undergone a historic and successful transformation.Around the "intelligent railway",the service concept of "people-oriented" is highlighted,cloud computing is scientifically utilized,and the data information platform of the intelligent traffic dispatching command system is designed under the background of intelligence,so that the efficiency is greatly improved in the command process of traffic dispatching.The main work of this paper is as follows:(1)By analyzing and studying the user definition,user requirements,system functions and business processes of the data information platform of the intelligent traffic dispatching and command system,it is proposed to construct the data information platform of the intelligent traffic dispatching and command system based on cloud computing technology and service-oriented SOA architecture technology.(2)Design the hardware structure,network and security structure of the system from the logical structure,service structure,data structure and other aspects of the data platform,and give a specific system architecture scheme.(3)The key technologies,virtualization technology,cluster management technology,data management technology,information security technology and other aspects of the data information platform based on cloud computing are analyzed.PowerDesigner is used to build the database relationship of the data information platform,and the specific implementation method is proposed.The programming verification and actual application in the project site are carried out.
