Design and Implementation of Unmanned Surface Vehicle for Water Quality Monitoring

River pollution is becoming more and more serious with the development of industry in developing countries. So, water-quality monitoring has become an urgent problem to be solved. Although there have been a lot of valuable studies in recent years, there exists the drawbacks such as lack of intelligence, automotive or flexible and more monitoring system needing to manipulate the related devices. Therefore, a water-quality monitoring wireless Unmanned Surface Vehicle (USV) is designed to aim at these deficiencies. Meanwhile, based on 4G communication module, communication USV sub-system is designed to adapt to long-distance transmission with TCP and HTTP communication protocols. On the aspect of control, the smart ship is using data interface and TTL interface to realize data transmission between sensors and controls. The automatic cruise algorithms are provides considering GPS positioning and 9-axis sensor. Finally, through the real experiments, USV can automotive move according with presetting path and gathering the sensing data.
