Abstract

The present invention provides an autonomous underwater robot wireless sensor network with dynamic nodes, including a main node as a surface gateway, a sink node and a sensor node as an information relay transmission intermediary, and the main node includes a radio modem and a water surface part. The lower part of the acoustic modem; the sink node includes a power amplifier, a signal processing unit and an interface gain control module for data transmission and communication with it respectively; the sensor node includes an autonomous underwater robot central control module and sensors loaded with various sensors The sensor module includes a navigation module and a motion planning module; the wireless sensor network of the autonomous underwater robot with dynamic nodes provided by the present invention is not driven by power, and the multi-dynamic nodes communicate with each other to transmit information, so as to ensure that the autonomous underwater robot can continuously adjust The actual position of the underwater robot is continuously adjusted to track the time-varying desired trajectory due to the speed tracking deviation.

Description

A Wireless Sensor Network for Autonomous Underwater Robots with Dynamic Nodes technical field The invention belongs to the technical field of underwater communication, be specifically related to a kind of autonomous underwater robot without dynamic node. line sensor network. Background technique [0002] The ocean has abundant resources and vast space. Underwater sensor networks are deployed in extremely complex and variable underwater In the environment, underwater sound is mainly used for communication. In terms of military applications, the increasing intelligence of underwater weapon systems requires Conduct command and control communications, such as communications between submarines, motherships and submarines or other underwater unmanned combat platforms. Under the vehicle to implement monitoring and navigation, and remote acoustic remote control of mines, etc. In civilian areas, such as underwater voice communication, industrial Industrial coastal telemetr...
