Description

A typhoon tracking and detection instrument information sharing method

technical field

The invention relates to the technical field of information processing, in particular to an information sharing method suitable for typhoon tracking and detection instruments.

Background technique

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.

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.

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.

The prior art can meet the requirements of information sharing to a certain extent; however, the prior art has the following defects:

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) 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.

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.

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.

The purpose of the present invention is to provide an efficient information sharing method suitable for typhoon tracking and detecting instruments, so as to solve the real-time sharing of typhoon data and improve the data sharing efficiency.

To achieve the above object, the technical scheme of the present invention is as follows:

An embodiment of the present invention provides a multi-modal information sharing method, including:

Preliminary analysis of the data returned by the typhoon tracking and detection instrument, and data grouping;

Receive data request instructions sent by users;

The data request instruction is sent to the data information sharing server, and the data request instruction is used to retrieve the data in the data information sharing server. Send data to the user.

Further, in the above scheme, the preliminary analysis of the data returned by the typhoon tracking and detection instrument includes:

The basic tracking algorithm (BP algorithm) is used to restore the typhoon light detection node data.

In the above solution, the data packet includes:

It is classified according to the detection methods used to obtain the data, including but not limited to the onboard typhoon detection radar carried by the airship, the airborne weather sensing node, and the fixed-point transmitter.

Further, the onboard typhoon detection radar carried by the airship mainly scans the typhoon inner core area, and can obtain the wind field distribution;

The airborne weather sensing node performs follow-up detection inside the typhoon, and obtains detailed data inside the typhoon, such as temperature, air pressure, humidity, wind direction, wind speed, etc.;

The fixed-point transmitter is used to perform fixed-point supplementary measurement on points where the measurement of the floating air weather sensing node is inaccurate or impossible to measure, and mainly performs targeted detection for wind eyes and eye strength.

Using the multicast-based communication protocol, the data is transmitted to all users in the user group at one time. Due to the high timeliness of the data, the point-to-point information transmission for each user obviously does not meet the requirements of efficient sharing;

Further, the multicast-based communication protocol includes:

When multiple users request data services from the data information sharing server, the data information sharing server presents multicast connections to the users, and groups users according to the content of the data service request to form user groups;

Further, when the number of users and user groups is small, a single-hop communication network is established, and a multicast distribution tree does not need to be established at this time;

Further, when the number of users is large, in order to ensure the stability of the data service, a multicast distribution tree is established. The data information sharing server specifies one or more relay stations according to the network status and through DRSI instructions to establish a multi-hop communication network. Information can be shared through the above single-hop communication network and multi-hop communication network;

Further, when the number of user groups is large, in order to further improve the data sharing efficiency, according to the inclusion or intersection relationship of the data required by the user group, an appropriate relay station is designated as the root relay station, and the root relay station is added to the user group with the inclusion or intersection relationship. , the data information sharing server shares some data with the root relay station, and the root relay station shares this data among two or more user groups.

An embodiment of the present invention provides a typhoon tracking and detection instrument data information sharing client, including a receiving module for receiving a data request instruction sent by a user; a data processing module for receiving data shared by a data information sharing server, and also capable of receiving DRSI The command is converted to a relay station; the data sharing module will be activated after becoming a relay station for data sharing.

An embodiment of the present invention provides a typhoon tracking and detection instrument data information sharing server, including: a receiving module for receiving a data request instruction; a network processing module for processing the data request instruction, and implementing the multicast-based communication protocol in the above solution User grouping, establishment of multicast distribution tree and setting of root relay station; data sharing module, used for data sharing, and can also send DRSI instructions.
