Abstract

The invention relates to the technical field of unmanned ship monitoring, and provides an unmanned ship flow velocity and flow measurement system, which realizes direct measurement of the flow velocity and flow of a ship body relative to a river and lake water body within the immersion depth by arranging a measurement pipeline for providing water body overflowing channels in the longitudinal and transverse directions on the ship body and arranging a flow meter on the measurement pipeline. A differential GPS module used for obtaining real-time position information of the ship body is arranged on the ship body, so that indirect measurement of the surface flow velocity of the river and lake water body is achieved, and a sonar detection sensor used for detecting and sensing the section water depth is arranged on the ship body, so that estimation and measurement of the river section flow are achieved. According to the scheme, accurate measurement of the flow velocity and flow of a surface blind area can be achieved based on the measurement pipeline, a quantitative basis can be provided for adjusting the energy output of a ship body energy supply module and the direction of a steering engine in real time, and therefore the action response precision of the unmanned ship control system can be effectively improved; and the system can be directly used for hydrological business work withcorresponding precision requirements.

Description

technical field [0001] The invention relates to the technical field of unmanned ship monitoring, and more specifically, relates to a flow velocity and flow measurement system for an unmanned ship. Background technique [0002] An unmanned ship is a fully automatic surface robot that can sail on the water surface according to preset tasks with the help of precise satellite positioning and self-sensing without remote control. The English abbreviation is USV (unmanned surface vessel), which combines ship, communication , automation, robot control, remote monitoring, networked system, information processing, motion control and other professional technologies, which can realize autonomous planning, autonomous navigation, autonomous environment perception, intelligent obstacle avoidance, long-distance communication, pattern recognition, real-time video transmission and network monitoring and other functions. ADCP (Acoustic Doppler Velocity Profiler) is currently widely used in th...
