【摘要】：伴随着传统海事信息系统和信息技术发展的步伐,目前业界所钻研的热点是:增进服务能力、提高资源利用率、促进航务海事信息系统的信息共享。在航务海事信息系统的建设中,海事信息化顶层设计与云计算都扮演着重要的角色,而面临的一个挑战是如何运用云计算技术,建设智慧化、规范化、高资源利用率、高扩展性和信息共享的航务海事信息系统。围绕航务海事信息系统的用户需求和航务海事资源的特点,本文内容如下:(1)研究了航务海事信息系统的现状和发展需求,分析了航务海事信息系统与云计算结合的必要性;研究了航务海事信息系统的支撑技术,包括海事信息系统顶层设计、云计算特点和一般体系架构;设计了基于云架构的航务海事信息系统总体方案和关键环节,分析了航务海事信息系统与云计算结合的优势。(2)针对航务海事信息系统的具体需求,设计了资源层、平台层、应用层三层结构的航务海事信息系统架构模型。第一层是平台层:将用户与资源进行对接,给予用户所需要的服务;第二层是资源层:通过虚拟化形成资源池;第三层是应用层:为用户提供统一接口。同时航务海事的资源划分、任务分割、资源调度这一系列重要环节,是航务海事信息系统建设中着重设计的对象,为此设计了资源划分和任务分割的模型,并在分割之后给资源与任务赋予相对的编号,利用资源调度器对任务和资源进行匹配。(3)针对现有VTS系统所存在的问题,提出将VTS与云架构结合的构想,将VTS信息接入到"一系统,两平台"上面去,通过云数据中心实现信息的共享与交互,使得所有的VTS系统可以实现信息共享,避免信息孤岛,提高航务海事巡航救助效率,提高交通组织预测能力,使VTS系统更加智慧化。本文的课题研究得到四川省航务海事信息化建设项目的支持。
[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.
