At present, river and lake water quality monitoring method is single and the monitoring range is limited, then the paper designs a river and lake water quality monitoring ship based on the autonomous navigation technique, including forward and reverse power module, battery power module, autonomous navigation module, obstacle avoidance module, automatic water taking module, water quality monitoring module and wireless transmission module. Use GPS and acceleration sensor to realize autonomous navigation when monitoring ship is subject to scheduled path. Use onboard multi-parameters water environment monitor and automatic water taking by mechanical arm to automatically gain water sample and real-time monitoring of water quality. At the same time, it can transfers to the upper computer by 3G network. On software, it designs handheld mobile device based on Android platform and remote monitoring software platform based on PC to receive water quality parameters sent by monitoring ship and path information for remote monitoring work status of water quality monitoring ship and the change of water quality. The autonomous monitoring ship promotes water quality monitoring effectiveness and reduces monitoring cost, at the same time, it gives real-time monitoring to water quality and makes accurate regulation to provide favorable technology support for river and lake water pollution monitoring and prevention.
