Abstract

Abstract: In order to realize water quality monitoring in full water depth and improve water environment problems in local waters through the same device to help high-quality development of fishery breeding, an underwater robot for fishery breeding was designed.The dynamic model of AUV was established to describe the 6-DOF complex motion of AUV and ensure its good stability in the process of underwater motion. The whole water depth water quality monitoring system and water quality improvement system were composed of multi-sensor technology and inertial navigation technology. The experiment was designed to observe and verify its movement process, which could realize the monitoring function of water quality parameters such as pH, temperature and dissolved oxygen. According to the return value, the water pH, dissolved oxygen and other conditions were improved, and its efficiency was verified by comparing with manual control mode and existing equipment control. The system has successfully realized the integration of water quality parameter collection and water quality improvement in fishery breeding, with high efficiency, strong reliability, and emancipation of human resources, and provides a new idea for the research of the underwater robot.

Key words: underwater robot, water quality monitoring, water quality improvement, integration
