Background

The unmanned plane is called unmanned plane for short, and is an unmanned plane operated by radio remote control equipment and a self-contained program control device. The machine has no cockpit, but is provided with an automatic pilot, a program control device and other equipment. The personnel on the ground, the naval vessel or the mother aircraft remote control station can track, position, remotely control, telemeter and digitally transmit the personnel through equipment such as a radar. The aircraft can take off like a common airplane under the radio remote control or launch and lift off by a boosting rocket, and can also be thrown into the air by a mother aircraft for flying. During recovery, the aircraft can land automatically in the same way as the common aircraft landing process, and can also be recovered by a parachute or a barrier net for remote control. Can be repeatedly used for many times. The method is widely used for aerial reconnaissance, monitoring, communication, anti-submergence, electronic interference and the like.

Some unmanned aerial vehicles are used in the agricultural field now, like unmanned aerial vehicle sprays insecticide, unmanned aerial vehicle seeding etc. when unmanned aerial vehicle sprayed insecticide, because the liquid medicine sprays along with gravity, the liquid medicine rocks easily in the medical kit to because the consumption of liquid medicine, the pressure of the liquid medicine of spout department is more and more little, makes the average volume that begins to spray be greater than the average volume that sprays at the back, and the inhomogeneous of spraying
