本发明涉及信息处理技术领域，特别是涉及一种适用于台风追踪探测仪器的信息共享方法。The invention relates to the technical field of information processing, in particular to an information sharing method suitable for typhoon tracking and detection instruments.
背景技术Background technique
台风危害极大，是世界上最严重的自然灾害之一，我国年均登录量位居世界首位，因台风造成的损失非常严重。然而台风的成因，结构演化的机理和移动强度的突变等仍是未解之谜。主要是因为无法对台风进行深入的观测，台风探测仪器是一种集抵近外侧、随动内测、定点补测为一体的台风探测仪器。仪器通过空基飞艇所携带的超视距宽带数据链，将艇载雷达和随动内测气象节点的数据传输到地面站数据中心。Typhoons are extremely harmful and are one of the most serious natural disasters in the world. my country ranks first in the world in terms of average annual registration volume, and the losses caused by typhoons are very serious. However, the cause of typhoon, the mechanism of structural evolution and the sudden change of moving intensity are still unsolved mysteries. The main reason is that in-depth observations of typhoons cannot be carried out. The instrument transmits the data of the onboard radar and the meteorological node of the follow-up internal measurement to the data center of the ground station through the over-the-horizon broadband data link carried by the space-based airship.
台风探测仪器获取的台风观测数据可以进行同化模拟，是诸多科研及政府部门研究和监视台风的重要依据，所以数据的共享是非常重要的。The typhoon observation data obtained by typhoon detection instruments can be assimilated and simulated, which is an important basis for many scientific research and government departments to study and monitor typhoons, so data sharing is very important.
由于台风瞬息万变，为了能够准确监视及预测台风的动向，数据的时效性要求较高，为了保障同化模拟的准确性，数据中心应向相关部门进行高效的数据共享。Due to the ever-changing typhoon, in order to accurately monitor and predict the trend of the typhoon, the timeliness of the data is required. In order to ensure the accuracy of the assimilation simulation, the data center should carry out efficient data sharing with relevant departments.
现有技术能够在一定程度上满足信息共享的要求；然而，现有技术存在如下缺陷：The prior art can meet the requirements of information sharing to a certain extent; however, the prior art has the following defects:
1)现有技术没有针对台风数据进行优化，没有考虑到不同数据的特征对传输方式的影响，无法适应当前场景的应用；1) The prior art is not optimized for typhoon data, does not take into account the influence of different data characteristics on the transmission mode, and cannot adapt to the application of the current scenario;
2)现有技术共享一般都需要专用的客户端配合才能实现数据的传输，数据消费者需要额外购买专用的客户端，并且开发相关的数据转换接口，造成资源的浪费，信息共享的效率也会降低。2) Existing technology sharing generally requires the cooperation of dedicated clients to realize data transmission. Data consumers need to purchase additional dedicated clients and develop relevant data conversion interfaces, resulting in waste of resources and the efficiency of information sharing. reduce.
基于以上原因，开发具有自主知识产权的能够向各数据需求用户高效共享台风数据的信息高效共享方法具有十分重要的意义。Based on the above reasons, it is of great significance to develop an efficient information sharing method with independent intellectual property rights that can efficiently share typhoon data with various data users.
为了实现高效的信息共享，可以对数据消费者进行分组，对不同组给予不同的权限，利用多播的技术手段，将符合通信群组权限的数据进行共享In order to achieve efficient information sharing, data consumers can be grouped, different groups can be given different permissions, and the data that conforms to the permissions of the communication group can be shared by using the technical means of multicast.
