The utility model also provides a kind of water quality detection method of sampling based on unmanned plane, includes the following steps:
First, safety inspection of taking off is carried out before unmanned plane takes off.Check unmanned plane and water quality detection sampling system
State it is whether normal, and ensure that the hose 21 on automatic capstan is in winding state and telescopic sleeve 321 is in retracted state.
Step 1 starts unmanned plane.Surface personnel controls unmanned plane during flying to taking by the remote control equipment of unmanned plane
Sample area and automatic pointing hovering;
Specifically, unmanned plane is after reaching sampling area overhead, by the rtkGPS locating modules and ultrasonic wave of unmanned plane itself
Fixed high module provides that Centimeter Level on horizontal and vertical latitude is other to be accurately positioned surely high information respectively.It is controlled in the flight of unmanned plane
Under the assistance of computer, maximum holding aircraft steadily hovering.
Step 2 transfers floating platform.Floating platform 1 is put to the water surface by master controller control automatic capstan;
Since unmanned plane and buoy can be influenced by wind and flow, small-scale relative motion can be caused, hose is used
The mode of 21 connections can make the two position have certain amount of redundancy, and the flexibility and safety of system is greatly improved.
Step 3, positioning are adjusted.Floating platform 1 is measured relative to unmanned plane using angle follower and laser emitter 131
Then position offset manipulates unmanned plane and moves so that floating platform 1 reaches sample point, by unmanned plane spot hover again;
Specifically, due to the influence of wind-force, positioning and the floating platform 1 of aircraft, the i.e. position of sample point is caused to exist centainly
Gap.Sample is more accurately sampled in order to obtain, we used light-angle locators to have carried out low-cost and high-precision to buoy
Positioning.So-called light-angle locator, particular content are one piece of speculums 13 of installation on buoy(Receiving terminal), aircraft end is equipped with
Angle follower and laser emitter 131.Fly control imu with unmanned plane(Angle state sensor)And rtkGPS(Differential type GPS)'s
Cooperation, angle follower and laser emitter 131 by the positioning of angle and distance can be achieved buoy position based on unmanned plane
The repositioning of position.Specifically, adjusting the angle of laser emitter 131 by angle follower, laser emitter 131 is made to emit
Light beam be irradiated on speculum 13, to which the distance of the light beam is displacement between unmanned plane and floating platform 1, and angle with
Corner with device is the differential seat angle between unmanned plane and floating platform 1, according to the displacement and differential seat angle between unmanned plane and floating platform 1
The position that the floating platform 1 can be calculated makes floating platform 1 reach appointed place finally by regulation and control unmanned plane.The localization method at
This relatively low, accurate positioning.
Step 4, depthkeeping.Instruction is sent out from master controller to microcontroller, microcontroller starts waterproof stepper motor 12,
The draft of intake pipe 11 is adjusted by driving the leading screw of lead screw pair 123 to rotate.
Step 5, sampling.Before sampling, water suction 20 seconds is carried out in the state that water delivery head 322 is not inserted into check valve 421.So
Actuator is controlled by master controller afterwards, driving telescopic sleeve 321 extends, and water delivery head 322 is allowed to be inserted into check valve 421;Then by
Master controller starts water pump 32, and intake pipe 11 draws water sample, and water sample enters reservoir chamber 41 through hose 21 and telescopic sleeve 321
It is interior.When water pump 32 sucks water sample in reservoir chamber 41, until check-valves 43 of the water sample in reservoir chamber 41 above reservoir chamber 41
After middle spilling several seconds, water pump 32 stops water suction.
Step 6 after the completion of the primary sample in step 5, is bounced back by master controller control telescopic sleeve 321, same to time control
Automatic capstan processed rolls hose 21.
Step 7, driving unmanned plane flies to, and simultaneously automatic pointing hovers for next sample region.
Step 8 repeats operation of the step 2 to step 7, carries out the multiple repairing weld of multi-point sampling.
While each sampled point carries out sampling operation, master controller is recorded by temperature sensor 15 and rtkGPS
Air themperature, water temperature and the location information of sampled point.

1, using the flight characteristics of unmanned plane, can allow user on the coast, the first-class safety zone of ship takes off, operates aircraft
Leap sandy beach, riverbed, forest-road, streams and severe desert terrain;Science water sampling simply and easily is carried out to sample region
Work;Reduce the time money input and increase personnel safety that personnel equipment expends in complicated landform work;
2, float type depthkeeping acquisition method more scientific and precise.The water sample of water surface can be due to water_air exchange, plant
The influence of the factors such as fallen leaves, floating refuse, the water body example acquired herein cannot represent the actual conditions of entire water body completely.
So we at least take the water sample of water surface or less 20cm as study sample;We provide the acquisition of buoy adjustable-depth formula
Mode disclosure satisfy that different research contents accurately control different sampling depth demands;
3,32 rotary harvester of water pump.Whole water intaking work of washing one's face and rinsing one's mouth can be completed using the device, be conducive to fill
The simplification set, lightweight;Motor 31 drive hollow shaft 3 rotate by way of, can make unmanned plane have multizone, it is more when
Between, the samplings of the various levels of more gradients, and it is excessive to ensure that sample independently preserves;It can amount to obtain by flight
Greatly, independent, reliable science sample, and subsidiary corresponding meteorological model geography information.
