Embodiment Construction

[0016] The present invention proposes an underwater and above-water integrated communication system for marine pastures based on a network of small buoy mooring chains. The detailed technical route is as follows.

[0017] Step 1. The composition of the underwater and above-water integrated network communication system of the marine ranch

[0018] The underwater and above-water integrated communication system platform of the marine ranch based on the network of small buoy mooring chains built in this project is as follows: figure 1 As shown, the left side shows the construction process of the whole platform, the water area to be monitored by the whole platform is 10, and the left side shows that the water depth is 100m, and 20 induction coupling mooring chains are deployed in the whole area, and the upper end of each is fixed on a small float , 6-8 temperature sensor nodes are placed under each chain, and the profile seawater temperature information is transmitted by inductive ...

Abstract

The invention provides a marine ranch underwater and overwater integrated communication system based on small floater anchor mooring chain networking according to the requirement of marine ranch intelligent monitoring three-dimensional network construction. A sensor network based on LoRaWAN wireless standard is built in a marine ranch. Seawater temperature information transmission of an underwaternode profile of the small float anchor mooring chain is completed underwater based on an inductive coupling transmission principle, the signal transmission performance is improved by using an OFDM algorithm, the small float anchor mooring chain is used as a network child node on water, a gateway node is arranged at a proper position, a server terminal is installed on a watch-over platform on water, and each child node, the gateway and the server form a wireless sensor network, a LoRa rate adaptive mechanism is used for guaranteeing the transmission rate of signals in the aspect of a protocol.The marine ranch underwater and overwater integrated communication system based on small floater anchor mooring chain networking provides a low-cost solution for monitoring and transmitting underwater data of the marine ranch.

Description

technical field [0001] The invention belongs to the technical field of marine communication, in particular to an underwater data monitoring and transmission system for marine pastures. Background technique [0002] Marine ranching and mariculture have become industries that make important contributions to food security and economic growth. Environmental monitoring of marine ranching and real-time monitoring of underwater breeding organisms are one of the important directions for the construction of marine ranching. The environmental online monitoring technology of traditional marine ranching mainly uses buoys to carry monitoring sensors to complete in-situ online measurement. This mode is expensive, cannot be deployed in large quantities, and is mostly limited to the sea surface, making the monitoring of wide-area water bodies a difficult problem. [0003] In this monitoring network, in order to realize the in-situ online monitoring of multi-parameters of the water quality...
