The invention discloses a hydrological survey device and method based on an unmanned aerial vehicle technology. The hydrological survey device comprises an unmanned aerial vehicle, a Doppler ultrasonic flowmeter, a camera, a wireless communication module, a data processing module, a PH sensor, a water depth sensor and a release mechanism. The Doppler ultrasonic flowmeter, the camera, the wirelesscommunication module, the data processing module and the release mechanism are connected with a rack of the unmanned aerial vehicle, the data processing module is connected with a PH sensor, a water depth sensor and a connecting piece of the release mechanism are connected and suspended on the lower portion of the unmanned aerial vehicle, and the unmanned aerial vehicle is controlled by an unmanned aerial vehicle control system to reach the position above a river channel. Data measured by the PH sensor and the water depth sensor are released through the release mechanism and received and sentthrough the wireless communication module, the data processing module processes the data, and the unmanned aerial vehicle is perpendicular to water flow and consistent with the water flow in speed during measurement. The device and the method overcome the problem of inaccurate measurement caused by incapability of being perpendicular to water flow and consistent with the flow velocity of the waterflow during original manual survey of river hydrology, and have the characteristics of simple structure, accurate measurement, facilitation of rapid and accurate discovery of a pollution source, andsimplicity and convenience in operation.

    一种基于无人机技术的水文勘测的装置及方法,它包括无人机、多普勒超声波流量计、摄像头、无线通信模块、数据处理模块、PH传感器、水深传感器和释放机构,通过多普勒超声波流量计、摄像头、无线通信模块、数据处理模块和释放机构与无人机的机架连接,数据处理模块和PH传感器、水深传感器与释放机构的连接件连接悬垂于无人机下部,通过无人机操控系统操控无人机抵达河道上空,通过释放机构释放PH传感器和水深传感器测量数据,通过无线通信模块接受和发送数据,数据处理模块处理数据,测量时无人机与水流垂直并与水流速度一致。本发明克服了原人工勘测河道水文时不能与水流垂直和不能与水流流速一致导致测量不精准的问题,具有结构简单,测量精准,有利于快速准确发现污染源头,操作简单方便的特点。
