机载水质定点分层采样装置设计与实现*

为了提高水质采样的自动化、精准化以及信息化水平，针对传统水质采样（人工采样和无人船采样）的低效率、高成本、周期长以及难以到达采样地点等问题，提出了利用无人机技术取代传统的水质采样方式，该装置由旋翼无人机、采样装置以及标准取水容器组成，其采样过程首先是通过拨动无人机遥控器上的开关按钮预先设置好采样深度，然后在无人机地面站输入经纬度信息使得无人机能够飞行到指定的采样地点，进而拨动遥控器上的一键采样按钮自动完成取水操作，最后再一次拨动遥控器上的返航按钮使得无人机自动返航回到初始位置。该方法相比于传统方式具有安全性高、成本低等优势，有利于推动水文仪器现代化发展。

Research on fixed point stratified sampling device of water quality in unmanned aerial vehicle

In order to improve the level of automation, precision and information of water quality monitoring. In view of the traditional water quality monitoring (such as, artificial sampling and unmanned ship satellite, etc.) of such problems as low efficiency, high cost and long cycle, unmanned aerial vehicle technology is proposed to replace the traditional water quality sampling method, which makes the sampling method more portable, diversified and authentic. The device consists of unmanned aerial vehicle, hoist device and water containers. In the sampling process, the sampling depth is set to flipping the switch button on the remote control, and then the latitude and longitude are input in the ground station so that the unmanned aerial vehicle can fly to the designated sampling location. Then, the one-button sampling button on the remote control is moved, and the return button on the remote control is moved again to make the unmanned aerial vehicle return automatically. Compared with the traditional methods, this method has the advantages of high security and low cost, and can promote the development of the modernization of hydrological instrument.
