Cloud Computing Based Railway Information Sharing Platform And Key Technologies Research

With the continuous development of railway information, the railway informationconstruction in China has made great achievements in the three main areas of the transportationorganization, passenger and cargo marketing and business management, and built a number ofinformation systems covering the whole aspects of the railway. However, existing businessinformation systems based on the original information architecture, each take its separateapplication as its center, so forming a "chimney type" layout in whole railway area, thus theexchange of sharing information encountered more obstacles. Makes the exchange of sharinginformation between business systems, improve overall coordination and comprehensive benefitsplay encounter greater obstacles. Change this situation as soon as possible has become an urgentproblem in the construction of railway information. Railway information sharing platform toachieve interoperability, information sharing, interaction and coordination, integrated applicationhas become a consensus, is also one of the key research in the field of information areas in recentyears, the research of service-oriented architecture SOA for information sharing platform has madeimportant achievements, the proposed solutions for application level information sharing and theimplementation of the application, but not involved in the architecture of the underlying resources,has not yet formed the comprehensive framework from the bottom.With the development of cloud computing theory and key technologies, the new solution isproposed for heterogeneous information sharing and comprehensive information utilization, relatedindustries at home and abroad have carried out research and exploration. Cloud computing is a wayof sharing IT infrastructure, which can connect varieties of resources together to form a resourcespool to provide IT services. Based on cloud computing to build the railway information sharingplatform, establish the physical resources pool and sharing resources pool, which provide servicesfor the railway information-sharing platform cloud user, play the comprehensive benefits ofinformation resources to meet the needs of exchange and sharing information, which provide anew way for building railway information sharing platform.The research of the theory and key technologies of cloud computing combined with therailway information sharing needs provide solutions for cloud-based railway information sharingplatform architecture, focus on cloud computing storage technology, cloud services and cloud security technology, provide solutions for common information storage, business functions serviceand the overall security of information sharing platform.The main contents of this article andinnovations are as follows:(1) Study the theory and key technologies of cloud computing, study building cloud-based railwayinformation sharing platform(CRISP), according to the cloud service deploying mode andinformation sharing characters and needs, proposed the new ideas of establishment of the CRISP.(2) Proposed the framework of cloud computing-based railway information sharing platform,described the logical architecture and physical architecture of the CRISP, put forward the schemeof storage, service allocating, monitoring and application in the CRISP, then adviced theimplementation scheme of the CRISP.(3) Study storage technology of the CRISP. Proposed cloud computing-based enterprise data centerand data storage strategy for the CRISP, adopt distributed storage technology and non-SQL datastorage model to form storage resources pool for the CRISP. Proposed the object-orientedinformation encoding method， realized the railway sharing information management in theCRISP.(4)Study services technologies for the CRISP. Proposed cloud-based services framework, servicecatalog management and service matching algorithm model can be used for the CRISP.(5) Study security technologies of the CRISP. Proposed information safety model andthree-dimentional protection system, study on the security protection based on the unified securitycenter and key technologies.
