Problems solved by technology

In the underwater acoustic communication network, nodes are randomly distributed in a large area of ​​the sea, which can realize information collection in a large area. However, because the propagation speed of sound waves in water is only 1500m / s, and the data transmission rate is limited to tens of kbps Therefore, it cannot meet the demand of large-capacity data transmission

Abstract

The invention provides an underwater data transmission system, which is used for meeting the data transmission requirement of underwater large data volume. The underwater data transmission system comprises a gateway node carrying an underwater acoustic communication machine and an underwater optical communication machine, an underwater monitoring node and an underwater communication node, and theunderwater monitoring node is used for sending first positioning navigation guide information to the underwater communication node through the underwater acoustic communication machine when monitoringdata needs to be sent. The underwater communication node is used for moving to a corresponding position according to the received first positioning navigation guide information, establishing underwater optical communication connection with the underwater monitoring node through the underwater optical communication machine, and receiving monitoring data sent by the underwater monitoring node, andreceiving second positioning navigation guide information sent by the gateway node after the monitoring data transmission is completed, moving the second positioning navigation guide information to acorresponding position, establishing underwater optical communication connection with the gateway node through the underwater optical communication machine, and sending the monitoring data to the gateway node through the established underwater optical communication connection.

Description

technical field [0001] The invention relates to the technical field of underwater communication, in particular to an underwater data transmission system. Background technique [0002] The communication industry in today's world is developing rapidly. Communication technology is widely used in the three major fields of sea, land and air. The development of land and air communication is relatively mature. However, due to the harsh underwater communication environment, there are many challenges in underwater communication technology. Therefore, There is still a lot of room for development. 70.8% of the earth's surface is covered by water bodies. Due to the abundant resources in the ocean, the development of ocean resources has greatly promoted the development of underwater wireless communication technology. Underwater wireless communication technology can be used in resource detection, environmental supervision, and auxiliary navigation, and is of great significance to strengt...
