example

[0018] In order to achieve the purpose of the present invention, as Figure 1-2 As shown, in the first implementation of the Beidou communication-based ocean autonomous observation platform data transmission method involved in the present invention, it uses Lagrange drifting buoys as an ocean autonomous observation platform example, and the method includes the following steps:

[0019] 1) Set multiple sets of Beidou communication modules and microprocessors connected to them on the signal transmitting terminal of the ocean autonomous observation platform, separate the big data from the collected data through the microprocessor, and compress the big data to form multiple data packets , multiple data packets are sent to the ground-based signal receiving terminal in parallel transmission through multiple groups of Beidou communication modules; among them, the Beidou communication module can be adjusted according to the length of the data, etc., and there is no specific quantity li...

Abstract

The invention relates to an oceanic autonomous observation platform data transmission method based on Beidou communication. Real-time transmission of big data and data breakpoint reissuing after satellite communication interruption are achieved on an oceanic autonomous observation platform through a Beidou communication system. The method mainly aims to solve the problems that bandwidth limitations of the Beidou communication system exist, oceanic autonomous platforms like Lagrange drifting buoys can be easily affected by stormy waves and therefore satellite communication interruption happens. Parallel data transmission is carried out by a plurality of groups of communication modules, data are packed, compressed and sent, and lost data are reissued through advantages of the communication modules, and therefore real-time transmission of the big data is achieved, and the data sending success rate and data transmission efficiency are improved.

Description

technical field [0001] The invention relates to the field of marine communication monitoring, in particular to a data transmission method of a marine autonomous observation platform based on Beidou communication. Background technique [0002] With the advancement of science and technology, the ocean element data acquired by the ocean independent observation platform is developing in a diversified, high-precision, and large-scale direction, and has become an important way to promote ocean observation to achieve three-dimensional real-time observation. At present, observers mainly obtain the observation data of the ocean autonomous observation platform in two ways: one is to recover the large-capacity data storage in the platform. This method is costly and cannot monitor the operating status of the platform in real time. , unable to obtain data); the second is to regularly transmit data to the data receiving end through near-shore wireless signal transmission or satellite comm...
