The invention discloses an underwater wireless sensor network gateway based on a beidou navigation system and a communication method thereof. The communication method comprises data transmission processing and data reception processing. The data transmission processing comprises receiving perception data from an underwater sensor network node, converting the perception data to be a data frame communication format of the beidou navigation system, and sending the perception data to the beidou navigation system in a subpackage manner according to a data packet in a preset format. The data reception processing comprises receiving a control command from the beidou navigation system, converting the control command data frame of the beidou navigation system to be a data frame communication format of the underwater wireless sensor network, and forwarding the control command to the underwater wireless sensor network. The underwater wireless sensor network gateway has satellite communication capability and underwater sound communication capability at the same time, and remote effective exchange of underwater wireless sensor network data with shore-based information data is achieved.
Description
technical field [0001] The invention relates to data exchange technology, in particular to an underwater wireless sensor network gateway and a communication method based on the Beidou navigation system. Background technique [0002] China is a land power, but also a sea power, and its sea area ranks among the top in the world. On the one hand, my country is rich in marine resources such as offshore oil and natural gas resources, tidal energy / wind energy resources, and fishery resources; on the other hand, marine security is an important part and important guarantee of national security. Therefore, it has high economic value and strategic significance to effectively develop and protect marine resources and maintain marine security. [0003] In many emerging marine science and technology fields, underwater wireless sensor networks have been increasingly widely used in the fields of water pollution monitoring, underwater resource exploration, marine geography and meteorologica...
