Multipoint fixed-length smart water quality sampling device based on multi-rotor unmanned aerial vehicle

Abstract

The invention provides a multipoint fixed-length smart water quality sampling device based on a multi-rotor unmanned aerial vehicle, and relates to the technical field of water sample collection. A smart water sample collecting and monitoring system based on a multi-rotor unmanned aerial vehicle comprises the multi-rotor unmanned aerial vehicle, a water collecting device, and a ground control station. The multipoint fixed-length smart water quality sampling device is characterized in that the ground control station is used for planning a route, transmitting a collection command, and displayingwater collection status information in real time; the water collecting device comprises a pump sampler and a sampling point position control device; the sampling point position control device is usedfor placing a liquid level transducer, a capacitor and a wire sensor to obtain the water body depth and data about the height between the unmanned aerial vehicle and the water surface, transmitting the water body depth and height data to a ground station, and determining a sampling point coordinate according to a water sample collecting rule; the pump sampler is used for sucking a water sample tobe tested through a sucking pump; and the outlet of the pump sampler is connected with a splitting hose for inputting the water sample into a plurality of sampling bottles of which the bottle cap bottoms are provided with capacitive sensors respectively. Thus, fixed-length quantitative water sample collection is realized.

Description

technical field [0001] The invention relates to a multi-point fixed-depth intelligent water quality sampling device based on a multi-rotor UAV, which belongs to the intersection field of UAV and water sample collection. Background technique [0002] In recent years, environmental safety has been a hot topic, due to the serious pollution of water resources due to the discharge of industrial, agricultural and domestic waste water. Pollution of surface water resources seriously threatens environmental security. In order to protect people's life and health, it is often necessary to carry out sampling tests on the water bodies of rivers, lakes and reservoirs. [0003] Traditional water sampling is usually manual on-site sampling. This sampling method requires a lot of preparation in the early stage, and the sampling period is long. It often encounters the harsh sampling environment, such as when the water surface is seriously polluted or there are a lot of floating objects, it i...
