Iridium-based deep sea intelligent buoy data communication system and communication method

Abstract

The invention discloses an iridium-based deep sea intelligent buoy data communication system and a communication method. The iridium-based deep sea intelligent buoy data communication system comprisesa data acquisition and processing system and an iridium communication machine which are mounted at a buoy end, and a shore-based receiving station, wherein the data acquisition and processing systemcomprises a data acquisition module, a data processing module and a storage unit, and is used for conducting data acquisition, storage, encryption, compression and data packaging of a buoy; the iridium communication machine is installed at the buoy end and used for conducting data transmission of the whole system; and the shore-based receiving station is used for receiving a data transmitting request of the iridium communication machine at the buoy end and generating a public key and a private key matched with the public key according to the request, the public key is transmitted back to the data acquisition and processing system to encrypt a data message, and the private key is used for analyzing the encrypted data message. According to the iridium-based deep sea intelligent buoy data communication system and the communication method disclosed by the invention, end-to-end asymmetric encryption channel transmission is adopted, so that not only is the communication data volume greatly compressed, but further the safety performance of the data is improved.

Description

technical field [0001] The invention relates to the technical field of deep-sea intelligent buoys, in particular to an Iridium-based deep-sea intelligent buoy data communication system and a communication method. Background technique [0002] The data of deep-sea smart buoys is the technical support of the global ocean environment observation network, which is of great significance for grasping the global climate change and ecological balance. For example, the buoys in the central and northern Pacific Ocean, the South Pacific Ocean, and the Arctic and Antarctic regions are expensive to maintain due to their complex sea conditions, and they are loaded with many sensors and a large amount of data, making communication more difficult. [0003] Because Beidou short-message communication does not cover the whole world, buoys still need to use Iridium and other satellite communication methods. Iridium communication satellites have low orbits, low information loss, and fast transmi...

AI Technical Summary

Problems solved by technology

For example, the buoys in the central and northern Pacific Ocean, the South Pacific Ocean, and the Arctic and Antarctic sea areas are expensive to maintain due to the complex sea conditions, and there are many sensors loaded at the same time, a large amount of data, and communication difficulties increase

[0003] Because Beidou short-message communication does not cover the whole world, buoys still need to use Iridium and other satellite communication methods. Iridium communication satellites have low orbits, low information loss, and fast transmission speeds. Disadvantages of poor real-time performance and low safety performance
