Construction And Application Of Unmanned Seawater Quality Monitoring Platform

With the great development of our country's abundant marine resources,the problem of marine pollution in coastal waters is becoming more and more serious.To strengthen the prevention and control of marine ecological safety pollution,to protect the marine ecological environment system and to maintain the safety of the marine ecological environment.This paper introduces the system of unmanned seawater quality monitoring platform from hardware and software.The hardware is composed of monitoring platform's hull and shorebased computer.The monitoring platform is composed of navigation obstacle avoidance module,collection and detection module,self-confirmation and self-diagnosis module.The unmanned Marine water quality monitoring platform is designed with a dual-body ship,twin propellers,and 316 stainless steel fully airtight structure,with solar and lithium batteries as the hybrid power,without secondary pollution.The intelligent detection system adopts the modularized structure,which can replace the sensor according to the test requirements,monitoring platform can be applied to water quality monitoring of offshore,river,reservoir and other water bodies.Software system based on LabVIEW2016 platform developed PID control software,wireless communication software,self-verification,self-diagnosis system and so on.The optimal path can be quickly developed by the monitoring platform based on the grid-ant colony algorithm,discrete-ant colony algorithm and potential energy trend shortest path planning algorithm.The monitoring platform can realize autonomous navigation,intelligent sampling and detection,self-verification,self-diagnosis,real-time transmission detection data to shore-based station management software analysis and record.The experimental application was carried out in the polytechnic lake and lingang port,and the functions of autonomous navigation,autonomous obstacle avoidance,wireless communication and intelligent sampling were verified.The test platform was used to carry out heavy metal detection of seawater in the test area,and safety assessment of heavy metal contamination was carried out in this area.
