Design And Implementation Of Cloud Computing Support Platform For The Information System Of Electric Multiple Units Depots

The Electric Multiple Units(EMU) balances the heavy burden of the railway transportation of our country, and the EMU depots are the place where the temporary maintenance work of the daily maintenance and sudden failure of the EMU take place, which is the security base of the normal operation of the EMU. However, during the process of the informatization construction, because of the short of the overall planning at the beginning, it causes the problem of imbalance usage of the computing resources and the big difficulty in system maintenance in the EMU depots information system.These problems decrease the work efficiency of the EMU depots and cause the waste of the computing resource; what’s more, they seriously slow down the process of the informatization development of EMU depots.In order to solve these problems appear in the process of informatization construction of the ENU depots information system, based on the basis of the research on cloud computing technology, the paper designs the cloud computing support platform that can satisfy the needs of the EMU depots information system. The cloud computing support platform of the EMU depots information system is composed of three layers, which are the basic resource layer, the service delivery layer and the data interaction layer from top to bottom.The basic resource layer completes the union of the computing resource of the EMU depots information system by designing a solution to the server、the network and storage virtualization. The service delivery layer can provide continuous cycle service including platform and application to the different business departments in the EMU depots by designing a solution to IaaS、PaaS and SaaS. The data interaction layer can call the services needed in the business departments in the EMU depots by designing a solution based on the Web Service.The paper makes the realization principle of the cloud computing support platform of the EMU depots information system, designs the solution to hardware and software, and applies the cloud computing support platform to the EMUdepots information system. Then it completes the construction of the redundant distributed information system, and does the functional test of the system. It analyses the improvements and profits that the introduction of the cloud computing into the EMU depots information system brings from the aspect of the practical application. The paper introduces the cloud computing into the informationization construction of the EMU depots, and proves the introduction of cloud computing, and effectively accelerates the speed of implementation the project of EMU depots information system, at the same time, greatly reduces the cost of construction of the EMU depots information system, and largely increases the operation rate of the resource of the information system and overwhelmingly decreases the manpower and material resources needed in the maintenance of EMU depots information system.
