Technical Field

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 method.

Background

The deep and open sea intelligent buoy data is a technical support of a global marine environment observation network, and has important significance for mastering global climate change and ecological balance. For example, buoys in the sea areas of the north-middle pacific, the south pacific and the north-south polar regions have complex sea conditions and expensive maintenance cost, and meanwhile, a large number of loaded sensors and large data volume increase communication difficulty.

Because the Beidou short message communication does not cover the world, the buoy still needs to adopt satellite communication modes such as iridium satellite, the iridium satellite communication satellite has low orbit, low information loss and high transmission speed and becomes the first choice of buoy data communication, but the defects of high communication cost, poor real-time performance and low safety performance exist at the same time.
