With the waste of water resource, guarantees the appropriate property sprayed insecticide, not only increase the spraying efficiency of pesticide, also greatly reduce pesticide
Pollution on the environment, so having good environmental protection characteristic.
However, unmanned plane, which carries out aviation plant protection operation, often to be influenced by weather or limit bigger, FRITZ etc. has studied gas
Influence as condition and nozzle type to aerial pesticide mist droplet deposition and float of mist droplet, it is indicated that wind speed is that both influences are most significant
Factor.Wang Ling etc. realizes the Variable Control of flow and fogdrop diameter using pulse modulation technology, utilizes wind tunnel test difference
Mist droplet deposition effect when wind speed, different fogdrop diameters.It may be said that the deposition rule of droplet is often to the operation effectiveness of aviation plant protection
Serve conclusive.But present unmanned plane plant protection operation often lacks the monitoring to mist droplet deposition, when leading to operation
The droplet sprayed out is influenced (especially natural wind) by various aspects and cannot get effective precautions, and this often leads to
Droplet drift is serious, the generation of duplication and leakage dimension in spraying phenomenon, so that operation effectiveness declines, the agriculture chemical droplet of drift is be easy to cause again
Environmental pollution.This system is intended to carry out one effectively to the droplet that unmanned plane plant protection operation sprays by the method for image analysis
Monitoring and feedback regulation, the phenomenon that drift and duplication and leakage dimension in spraying to reduce droplet, promote aviation plant protection operation quality.
Utility model content

The agricultural plant protection unmanned plane sprinkling system repaid can be monitored in real time unmanned plane aviation plant protection operation mist droplet deposition drift, and make
Respective feedback is affected by the external environment can not the monitoring of float of mist droplet with reducing float of mist droplet to solve unmanned plane plant protection operation
With resprayed caused by adjusting, the decline of drain spray and operation effectiveness and agriculture chemical waste and the problems such as environmental pollution, while
Unmanned plane plant protection operation is improved for the utilization rate and operating efficiency of weather and other environmental suitabilities and plant protection drone.
To achieve the above object, technical solution provided by the utility model are as follows: a kind of band droplet drift detection is automatic to mend
The agricultural plant protection unmanned plane sprinkling system repaid, including respectively be loaded on unmanned plane on image acquisition units, image analyzing unit and
The spray unit of angle adjustable；As front, described image acquisition unit is located at direction of advance when wherein, using unmanned machine operation
The rear of spray unit, and timing acquiring image sends image analyzing unit to and is analyzed and processed, and obtains the spray of spray unit
The angle that head direction should deflect；The spray unit includes medicine-chest, drug liquid tube, steering engine, spray boom, spray head, wherein the medicine-chest
It is fixed on unmanned plane with steering engine, and the spray boom is connect by drug liquid tube with medicine-chest, and is deflected by steering engine control, it is described
Spray head is mounted on spray boom, by deflecting the spray boom of respective angles to realize the real-time compensation to spray head droplet drift value.
Described image acquisition unit is Airborne Camera.
The utility model compared with prior art, have the following advantages that with the utility model has the advantages that
1, it obtains Pcnten-1 yne-4 image in real time using image analysis technology and is analyzed, it can be to unmanned plane plant protection operation
Quality carries out an effective monitoring.
2, spray unit is fed back to when by the fructufy of image analysis acquisition, adjusts the angle of sprinkling, it is possible to reduce droplet
Drift amount, promote the deposition of droplet, thus prevent from respraying, drain spray is to promote operation quality, reduce the waste of fertilizer and pesticide
And the pollution of environment, unmanned plane plant protection operation can also be promoted to the adaptability of environment, promote the utilization rate of plant protection drone
With the efficiency of plant protection operation.
It 3, can be to entire unmanned plane plant protection operation process by acquisition, analysis and the storage to operation process droplet image
