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.

    本发明涉及无人船监测的技术领域,提出了一种无人船流速流量测量系统,通过在船体上布置用于提供纵横方向的水体过流通道的量测管路,在量测管路上设置流量计从而实现了船体在浸没深度内相对河湖水体的流速流量的直接测量,通过在船体上设置用于获取船体实时位置信息的差分GPS模块从而实现了河湖水体表面流速的间接测量,通过在船体上设置用于探测感知断面水深的声呐探测传感器从而实现了河流断面流量的估算测量。本发明的上述方案基于量测管路能够实现表层盲区的流速流量精确测量,可为实时调整船体供能模块的能量输出和舵机方向提供定量化依据,从而能够有效提升无人船控制系统的动作响应精度,可直接服务于具有相应精度要求的水文业务工作。
