Brief introduction of plant protection UAV: plant protection UAV, also known as unmanned aerial vehicle, as its name suggests, is an unmanned aircraft used for agricultural, forestry and plant protection operations
This type of UAV is composed of three parts: flight platform (fixed wing, helicopter and multi axis aircraft), navigation flight control and spraying mechanism
It can realize spraying operations through ground remote control or navigation flight control
It can spray chemicals, seeds and powders
At present, the main problems are as follows: 1
There are few mature and reliable plant protection UAVs
Many manufacturers blindly seek to be big and ignore the special requirements of plant protection operation
2
Buyers buy blindly
As a new spraying technology, if they want to really use it for agricultural, forestry and plant protection, buyers should investigate the flight prevention operation on the spot, learn more about it from the technical level, and then start
3
The training and after-sales service were not up to standard
The buyer didn't dare fly
It was just a decoration
4
The knowledge of special pesticides is insufficient, and individuals blindly mix pesticides, which is prone to high pesticide residues and poor pest control effect
5
It is difficult to formulate industry standards and apply for machine purchase subsidies
6
The market demand is large, the entry threshold is not high, and it is difficult to improve the level of specialization
The utility model relates to a remote-control agricultural spraying small aircraft, which is small and powerful, and can carry 8-10 kg of pesticides
Spraying pesticides at low altitude can complete the operation of one mu of land per minute
Its spraying efficiency is 30 times higher than that of traditional manual spraying
The aircraft adopts intelligent control
The operator controls it through the ground * and GPS positioning
The downward air flow generated by its rotor helps to increase the penetration of fog flow to crops, with good control effect
At the same time, the remote control of pesticide application greatly improves the safety of pesticide spraying
It can also carry out real-time monitoring of agricultural diseases and pests by carrying video devices: the unmanned small helicopter has the advantages of low operating height, less drift, hovering in the air, and no special airport for taking off and landing
The downward air flow generated by the rotor helps to increase the penetration of fog flow to crops, with high control effect
The remote control operation avoids the risk of pesticide exposure for spraying operators, It improves the safety of spraying operation and many other advantages
In addition, the electric unmanned helicopter spraying technology can save at least 50% of the pesticide consumption and 90% of the water consumption by adopting the spray spraying method, which will greatly reduce the resource cost
Compared with the oil powered UAV, the electric UAV has small overall size, light weight, lower depreciation rate, low labor cost per unit operation and easy maintenance
Body features: 1 High efficiency brushless motor is used as power The fuselage has small vibration, and can be equipped with precision instruments to spray pesticides more accurately; 2
the terrain requirements are low, and the operation is not restricted by altitude
It is located in Tibet, Xinjiang and other high altitude regions; 3
short takeoff adjustment, high efficiency and high attendance; 4
environmental protection, no waste gas, in line with the national requirements for energy conservation and environmental protection and the development of green organic agriculture; 5
easy maintenance, low use and maintenance cost; 6
small overall size, light weight and easy to carry; 7
provide power supply guarantee for agricultural UAV
8
it has the functions of real-time image transmission and real-time attitude monitoring 9 The spraying device has a self stabilizing function to ensure that the spraying is always vertical to the ground 10 Semi autonomous takeoff and landing, switching to attitude mode or GPS attitude mode, you can easily operate the helicopter to take off and land smoothly by simply manipulating the throttle lever
11
runaway protection: when the helicopter loses the remote control signal, it can automatically hover in place and wait for the signal to recover
12
the fuselage attitude is automatically balanced, the rocker corresponds to the fuselage attitude, and the most beautiful attitude is inclined by 45&\730;, It is suitable for smart and large maneuvers
13
GPS attitude mode (not available in the Standard Version, which can be obtained by upgrading), precise positioning and altitude locking
Even in windy weather, the accuracy of hovering will not be affected
14
the tail rotor and main rotor power of the new plant protection UAV are separated, so that the motor power of the main rotor is not consumed by the tail rotor, further improving the load capacity, and strengthening the safety and controllability of the aircraft
This is also a direction for the development of unmanned helicopters
15
the high-speed centrifugal nozzle design can not only control the spraying speed of the liquid medicine, but also control the size of the drops, with a control range of 10-150 microns
Operating environment: weather factors: flight is strictly prohibited in rainy days; operation is suspended in the weather with wind force greater than 4; operation is strictly prohibited in the weather with wind force greater than 6
Geographical factors: buildings without personnel living within 10 meters around the operating field
There is no shelter forest, high-voltage line tower, electric pole and other obstacles within 10m around the working field
There is no obstacle affecting flight safety or flight sight in the middle of the operation field
There are suitable takeoff and landing points for aircraft around or in the middle of the field
The crop height shall be lower than the operator's line of sight, and the operator can observe the flight attitude of the aircraft
The operation field shall have roads suitable for operators
Precautions: 1
Keep away from the crowd! Safety always comes first, safety comes first! 2
Before operating the aircraft, it is necessary to ensure that the batteries of the aircraft and * are fully charged before relevant operations
3
It is forbidden to operate the aircraft after drinking
4
It is strictly forbidden to fly on the head
5
No flying when it rains! Water and vapor will enter the transmitter from the antenna, rocker and other gaps and may cause out of control
6
It is forbidden to fly in the weather with lightning
This is very, very dangerous! 7
Be sure to keep the plane within your sight
8
Fly away from high voltage lines
9
Installing and using the remote control model requires professional knowledge and technology
Incorrect operation may cause equipment damage or personal injury
10
Avoid pointing the antenna of the transmitter to the model, because this is the angle of the weakest signal
Use the radial direction of the transmitter antenna to point to the controlled model, and avoid * and the receiver close to metal objects
11
The 2
4GHz radio wave propagates almost in a straight line
Please avoid obstacles between * and the receiver
12
If the model falls, collides, soaks in water or other accidents occur, please do a full test before the next use
13
Keep models and electronic devices away from children
14
When the battery pack voltage of * is low, do not fly too far
Check the battery pack of * and receiver before each flight
Do not rely too much on the low-voltage alarm function of * because the low-voltage alarm function is mainly used to prompt you when you need to charge
If there is no electricity, the aircraft will be out of control directly
15
When you put the * on the ground, please pay attention to placing it horizontally rather than vertically
Because it may be blown down by the wind when it is placed vertically, it may cause the accelerator lever to be accidentally pulled up, causing the movement of the power system, which may cause injury
