基于云架構(gòu)的航務(wù)海事信息系統(tǒng)體系結(jié)構(gòu)研究
[Abstract]:With the development of traditional maritime information system and information technology, the hot spot of the industry is to improve the service ability, improve the utilization rate of resources, and promote the information sharing of aviation maritime information system. In the construction of maritime information system, maritime information top-level design and cloud computing both play an important role, and one of the challenges is how to use cloud computing technology to build intelligence, standardization and high resource utilization. A maritime information system with high expansibility and information sharing. According to the user demand of aviation maritime information system and the characteristics of aviation maritime resources, the contents of this paper are as follows: (1) the present situation and development demand of aviation maritime information system are studied. The necessity of combining shipping maritime information system with cloud computing is analyzed. The supporting technology of shipping maritime information system is studied, including the top-level design of maritime information system, the characteristics of cloud computing and the general architecture. The overall scheme and key links of the maritime information system based on cloud architecture are designed, and the advantages of the combination of the maritime information system and cloud computing are analyzed. (2) according to the specific requirements of the maritime information system, the resource layer is designed. Platform layer, application layer three-tier structure of aviation maritime information system architecture model. The first layer is the platform layer: the user and the resource are docked to give the service that the user needs; the second layer is the resource layer: the resource pool is formed by virtualization; the third layer is the application layer: providing a unified interface for the user. At the same time, a series of important links, such as resource division, task segmentation and resource scheduling, are the object of emphasis in the construction of aviation maritime information system, and the model of resource division and task segmentation is designed. After segmentation, the relative number of resources and tasks is assigned, and the resource scheduler is used to match the tasks and resources. (3) in view of the problems existing in the existing VTS system, the idea of combining VTS with cloud architecture is put forward. The VTS information is connected to the "one system, two platforms", and the information is shared and interacted through the cloud data center, so that all VTS systems can share the information, avoid the isolated island of information, and improve the efficiency of maritime cruise rescue. Improve the prediction ability of traffic organization, make VTS system more intelligent. The research of this paper is supported by the maritime information construction project of Sichuan Province.
