Water quality probe depth keeping system and method suitable for unmanned aerial vehicle

Abstract

The invention belongs to the technical field of unmanned aerial vehicles and discloses a water quality probe depth keeping system and method suitable for an unmanned aerial vehicle. The water qualityprobe depth keeping system comprises a sling length sensing unit, a height detector and a sling retracting unit carried on an unmanned aerial vehicle load; the sling length sensing unit is used for detecting the length of a released sling, the height detector is used for detecting the flying height of the unmanned aerial vehicle; during working, the sling is attached to the sling retracting unit and used for suspending a water quality probe, the sling retracting unit determines the length of the sling required according to the detection results of the sling length sensing unit and the height detector and controls the retraction of the sling, so that the water quality probe is at the target underwater depth. By means of the water quality probe depth keeping system and method, the controllable and adjustable underwater depth of the water quality probe suspended by the unmanned aerial vehicle is achieved, the underwater depth can be dynamically and automatically adjusted during the operation, and depth keeping acquisition or detection is achieved.

Description

technical field [0001] The invention belongs to the technical field of environmental detection, and more specifically relates to a water quality probe depth determination system and method suitable for unmanned aerial vehicles. Background technique [0002] One of the steps in water quality testing is to collect water samples. It is inconvenient to take deep water samples under water by manual operation, and it is impossible to sample water from places where workers cannot approach, which brings great inconvenience to water quality testing. With the development of UAV technology, in the sampling process of water quality testing, the use of UAV as a vehicle for water quality sampling can overcome the above defects of manual sampling. The use of drones for water sampling usually uses the cable carried by the drone to lower the probe or container carried by the drone to the sampling point for water collection, or use the carried water pipe to extract the collected water samples...
