LKJ Basic Data Storage And Interaction System Based On Data Center

At present,the LKJ system is equipped with 21,000 locomotives and more than 1,000 EMUs which running on 250 km/h Dedicated Passenger Line.The LKJ basic data is the core foundation for the implementation of control function,which is updated synchronously with the changes of transport infrastructure,technical parameters of facilities,changes of traffic organization or construction of railway lines.In 2018,there were 1748 times of LKJ basic data changing and the data reloading involved in 486513 locomotives/EMUs.The frequent data changing have brought higher demands on LKJ data handover and safe storage operations.There are risks of inefficiency and low security by human-oriented model,which has not enough to ensure the safety and efficiency of data operations,and it is gradually becoming the bottleneck of railway transport efficiency upgrading.At the same time,with the upgrading of LKJ-15 system,how to plan for an upgrading of LKJ data operation mode from a higher level,considering the current situation of bureaus,and a smooth transition compatible with the two products is one of the major concerns at this stage.According to the requirements above,this paper presents the overall design idea of LKJ data center,researches the key technologies of data storage redundancy and data synchronization processing of remote data disaster preparedness,and designed the data storage and synchronization scheme of LKJ data center;researches the network security technology,data encryption transmission technology,combined with the current situation of Railway internal and external network isolation,and designed a system security transmission scheme that meets the basic requirements of national information security;Through the research of system integration technology,designed the overall software and hardware integration scheme;researches and have implemented the LKJ basic data storage and interaction function and security scheme based on data center mode,and it was verified in one Railway Bureau.Through the research of this paper,a new job system architecture based on LKJ data center is established,which provides a technical method for centralized management and control of the LKJ basic data in the whole railway.By strengthening LKJ data storage,sharing and supervision mechanism,we can effectively improve the quality and efficiency of LKJ data operation,so as to release more vitality to adapt to the development of railway transportation.
