Beidou communication method for efficient transmission of buoy data

Abstract

The invention relates to a Beidou communication method for efficient transmission of buoy data. Data communication is realized by the aid of a Beidou satellite, the buoy data are transmitted, and the method mainly includes functional steps implemented by a power query mechanism, a data retransmission and storage mechanism and a data reissue mechanism. The Beidou communication method has the advantages that by the aid of the power query mechanism, a Beidou communication platform is effectively and reasonably used, the probability of data transmission failure is reduced, working time of the Beidou communication platform is shortened, and the power consumption of a system is reduced; by the aid of the data retransmission and storage mechanism, on one hand, the success rate of data transmission can be increased, and on the other hand, integrity of the buoy data is ensured by storing the data failed in transmission; by the aid of the data reissue mechanism, the Beidou communication platform is effectively used, and the success rate of data transmission during working of the system is greatly increased by the aid of data reissue.

Description

technical field [0001] The invention relates to the field of data transmission by satellites for marine instruments, in particular to a Beidou communication method for efficiently transmitting buoy data. Background technique [0002] Drifting buoys can work long-term and covertly at sea. They are used to collect information about moving targets in water and environmental noise under various sea conditions, and send the processed data to the ground receiving station through satellites, which has important utilization value. At present, marine instruments mainly use foreign commercial satellites and my country's Beidou satellites in terms of data transmission using satellites. Foreign commercial satellite data transmission performance is mature and stable, but the cost is high, and there are hidden dangers of information leakage. Based on the consideration of cost, data security and confidentiality, follow-up technology development and other factors, the drifting buoy adopts ...

AI Technical Summary

Problems solved by technology

[0003] First of all, the current Beidou communication platforms all work in a continuous power supply mode, which consumes a lot of power during their work, while drifting buoys need to work in the ocean for a long time, and their power is supplied by batteries, which are affected by the buoy volume, counterweight and cost, etc. Affected by many factors, the capacity of the battery is limited, which determines that the Beidou communication platform cannot work in a continuous power supply mode, and the data that can be used for reference in its intermittent power supply mode is still relatively scarce, so it is necessary to design a reasonable application mechanism for the Beidou communication platform , so as to increase its efficiency

[0004] Secondly, the Beidou communication platform is affected by its antenna position and weather conditions, and data packets will be lost during message transmission.

Drifting buoys work in the ocean for a long time, and the Beidou communication platform it carries must also encounter various complicated sea conditions. If a reasonable and effective data transmission mechanism is not adopted, a large amount of data will inevitably be lost, thereby reducing the overall system performance
