Design concept of a plant protection drone
First, plant protection drone introduction
The definition of agricultural plant protection drone , as its name suggests, is a drone for agricultural and forestry plant protection operations. This type of unmanned aircraft has a flight platform (fixed wing, single rotor, multi-rotor), GPS flight control, and spray mechanism. Through the ground remote control or GPS flight control, the spraying operation can be realized, and the medicine, seeds, powder and the like can be sprayed. Because the agricultural plant protection drone is small in size, light in weight, convenient in transportation, vertical take-off and landing, and flexible in flight control, it has good adaptability to different regions, different plots, and different crops. Therefore, no matter in the north or south of China, hills or plains, large plots or small plots, agricultural plant protection drones have broad application prospects.
The agricultural plant protection drone is a kind of remote-controlled agricultural spray small aircraft. The body type is petite and powerful. Take the electric plant protection drone with a load of 10 kilograms as an example. The spraying efficiency is 30 times that of the traditional artificial, 300 per day. ~500 acres. The aircraft adopts intelligent control, and the operator controls it through the ground remote control. The downward airflow generated by the rotor helps to increase the penetration of the mist flow to the crop, and the control effect is good. At the same time, the remote control application greatly improves the application. Safety of pesticide spraying. The flight platform can also carry out real-time monitoring of agricultural pests and diseases, rural land confirmation, crop growth and pest and disease monitoring, application, pollination and fertilization operations by carrying different mission systems.
Second, plant protection drone reference performance indicators
This article describes the case of Shandong China Coal Group model: ZM-KT-10-8
· High-efficiency brushless motor is used as the power, the vibration of the fuselage is small, and it can be equipped with precision instruments and spraying pesticides more accurately.
· Low terrain requirements, operations are not limited by altitude, in high altitude areas such as Tibet and Xinjiang;
· Short take-off adjustment, high efficiency and high attendance rate;
· Environmental protection, no waste gas, in line with national energy conservation and environmental protection and green organic agriculture development requirements;
· Easy to maintain, low cost of use and maintenance, generally free to operate in 7 days;
· The price is relatively low and the degree of popularization is high;
· Load range 5-15L;
· The single operation time is usually about 10 minutes, and the working area is 10-30 acres/shift;
· Using lithium battery as the power source, the field operation needs to charge the battery in time;
· Specialized training;
Third, plant protection drone components
(1) Configuration
Plant protection drones have higher configuration requirements (not accessories) due to load.
1. Flight control: directly related to the stability of the drone, commonly used brands are Dajiang, Zero, APM, Yutu, KK, QQ, etc.;
The price ranges from a few hundred to tens of thousands. The brands commonly used by plant protection drones are DJI and ZERO.
2. ESC: Ko nTRONIK JIVE, ZTW, Haoying, YGE, Phoenix, etc.;
The price of dozens, hundreds to thousands of market-based plant protection machines mostly use ZTW, good profit, and high cost performance. It is too wasteful to be like Ko nTRONIK JIVE (except for local tyrants). The most attention to the ESC is the maximum instantaneous discharge current. It is used with a pair of brushless motors. It is not necessary to just mix it with you.
3. Brushless motor: T Motor, Hengliyuan, Langyu, Maya, JFRC, etc.;
The price is several tens of hundreds of thousands, and the motor should look at the KV value (the KV value of the brushless motor is defined as the speed/V, which means that the input voltage is increased by 1 volt, and the rotational speed of the brushless motor is increased by the idle speed).
4. Paddle: The size of the plant protection machine blade depends on the size and pitch. There are too many brands. An ordinary processing plant can do it.
The combination of ESC, motor and blade directly affects the load of the plant protection machine.
5. Receiver: Plant protection, six channels are enough
6. Remote control: wfly (Tiandifei Technology Development Co., Ltd. remote control equipment brand) FUTABA (Japan Futaba Corp.) Futaba Electronics Technology Development Co., Ltd. was established, the main business scope includes wireless remote control transmission equipment, R&D, production and sales of electronic industrial products such as VFD fluorescent display devices and logistics software.)
7. Racks and landing gears We all play our own boards and design ourselves.
The phone cable is the cable that connects the phone to the computer.USB Cable general data line rarely dedicated, the general phenomenon is that a data line can be used for a variety of mobile phone models,some models of data line is exaggerated,a line can use 30-40 different types of mobile phones.General data lines are rarely dedicated, the general phenomenon is that a data line can be used for a variety of mobile phone models, some models of data lines are exaggerated, a cable can use 30-40 different types of mobile phones.
Mobile phone data cable and charging speed has a relationship.The cable connects the phone to the charging head and is mainly responsible for current transmission,so inevitably,it will also affect the charging speed.In addition, the length of the data line also has a certain impact on the charging speed.The shorter Usb Cable Type C is,the faster the charging speed will be. Generally, the standard data line of mobile phones is 1 meter, but in the selection of different use scenarios can also match different lengths of data lines.The charging speed and charging head are also affected by the charging head of the mobile phone.When charging a phone, the charging head determines the amount of voltage and current. Regular charging heads are marked with voltage and current output.
Different quality data line thickness, length are different, generally should try to choose the wire diameter thick, wire surface is not reflective and the wire is long enough data line, the thicker the wire.It is proved that its tensile strength is high and it has a good protective effect on copper core.The more the wire surface is not reflective, the more the composition of the rubber in the wire, the better elasticity of this data line, anti-aging, not easy to break, the wire is long enough, it will be quite free in use.
