The use of agricultural drones is gradually entering the public's field of vision. The advantages of high operating efficiency, safety and environmental protection, water-saving and medicine-saving, and at the same time saving a large amount of labor and saving agricultural input costs are gradually recognized. Many plant protection service teams have sprung up, but the bomber is a test that needs to be faced in plant protection and flight defense services.
How to reduce this phenomenon, we began to analyze the reasons for the crash:
1.Not ready before the flight
After the inspection is completed, the aircraft operator must periodically inspect all parts of the plant protection drone before each use, from front to back, top to bottom, and from outside to inside. After each flight, clean the fuselage, rotor, landing gear, spray system, etc., check that the screws of the main components of the aircraft are firm, whether the moving parts are too large, the arms are firm, and whether the body is obvious. Crack, etc.
Before the agricultural drone takes off, it must be enough to take off and many accidents can be avoided.
2.Too low a flight position leads to crops
In the homework, there are often farmers on the side, they often say: "Fly low, low, low, the better." In order to satisfy customers, some flying hands will fly very low, if I didn’t see the high-crop crop, and I fell without paying attention.
Therefore, when flying hands, do not interfere with the people around you, concentrate your attention, communicate with the observers, and try to keep the plane more than one meter away from the crop.
3.Magnetic field disturbance is out of control
On the operation route, if the aircraft is close to the high-voltage line and the voltage is high, the aircraft is likely to be out of control due to electromagnetic interference.
If the agricultural drone is working, if you find a high-voltage tower around, do not take off nearby. If it is a signal tower, it is generally a little far away. If it is an electronic fence, then you must fly according to the requirements of the electronic fence.
4.The drone driver and the observer's intercom are dead or faulty.
In the plant protection operation, this is also the cause of the bomber that is easily overlooked. When the pilot controls the aircraft to fly forward, there is a slight error in the visual observation, and there is less communication between the observer and the driver. If there is no electricity or failure, the driver or observer does not know it, and it is very likely to hit the tree or other things.
It is recommended that the driver and the observer agree on the operation. For example, the observer gives the flying hand a message every five seconds. If he does not hear the speech after the time, he immediately controls the aircraft to hover. In this way, even if the driver does not see the plane while maneuvering the aircraft, the bottom of the heart is also there, and the problem with the intercom can be found immediately.
The life of agricultural drones on the market is usually between 10-20 minutes. Agricultural drones consume more energy when the drug load is relatively large. When spraying pesticides, there is sometimes a low battery alarm, but there is still some liquid in the medicine box. If you have a flying hand, it is convenient to try to finish the liquid and then land. Coupled with a relatively large proportion of liquid, the remaining power of the aircraft cannot support continued operation and return to the air, forcing a direct fall on the way or directly in the air.
Therefore, the driver must plan to prepare before the operation, preferring to fly less than 1 hectare instead of challenging the limits of the aircraft.
6.Attitude mode causes impact
The aircraft has no GPS positioning in the attitude mode, so it will be affected by the environment and drift. However, some flying hands do not know how to operate when they are not fully familiar with the attitude mode, so the plane crashes.
On the one hand, it is a simple operation error. For example, if you accidentally turn the direction, you will not operate. For example, if you pick up the remote control, you don't know what to do. If you accidentally hit a wall, tree, pole, etc.
On the other hand, when working, I often can't see the plane without paying attention. The actual plane is still flying safely, and the flying hand is panicked and hits a few shots indiscriminately, and it may hit something. In the course of this operation, it is necessary to communicate with the observer to ensure that the aircraft is flying stably.
For example, there are invisible obstacles, visual errors, windy, fatigue flying, etc. at the job site.
In order to try to operate the bomber caused by mistakes, it is necessary to pass the job in the agricultural work in addition to the driver's skills. The field experience is also very important.
