On July 8, 2023 local time, the Minister of Strategy Industry of Ukraine said that the Ukrainian Ministry of Strategy Industry and the Turkish Industry and Technology Department signed a memorandum of the development of the UAV industry in Ukraine.

In winter, the temperature gradually decreases, especially the temperature in the north direct cliff -type cooling. Low temperature and cold will have a different degree of impact on various devices of the drone. Safety. 1. Take off UAVs observe the surrounding environment before taking off to ensure that the power of the remote control, drone and other electronic equipment is full of electricity. After taking off, keep the aircraft hanging for about 1 minute to help the battery fully warm up. 2. Flight Avoid continuous flights under low -temperature environments, and more electricity is reserved for returning to flights than room temperature. Do not use a high -mobility posture for a long time to prevent the battery voltage from falling sharply and prevent fragile plastic parts from being damaged in low temperature environments. Avoid the environment where the temperature difference changes violently, and prevent hidden safety hazards such as sensor abnormalities and frozen components. Avoid flying above the lower altitude (within 5m) or strong reflective areas above the snow to prevent the visual sensor from working abnormal. If the APP operating system is prompted by abnormal flight safety during flight, please land in time. 3. landing When the outdoor temperature is low, it will directly condense the drone from the outdoor abroad to the indoor room with heating. It may cause the flight control system and the electronic speed regulator to be affected by condensate, which will cause failure. Therefore, it is necessary to dehumidify or dehumidify it after the drone flight is over to prevent the liquid from entering the drone. Drone equipment is stored in the protective box and stored in an environment of 5-20 ° C to keep the environment dry and avoid direct sunlight. Low -temperature and high temperature environments will accelerate some components of the drone, so regular maintenance of the drone will not only ensure the use efficiency of the drone, but also avoid accidental risk of drones.

A 50L sprayer drone is a type of agricultural drone that is used to spray pesticides, herbicides, and fertilizers on crops. It has a tank capacity of 50 liters, which allows it to cover a large area of land in a single flight. The drone is equipped with a spraying system that can be adjusted to control the amount of liquid sprayed per unit area. It is also equipped with GPS and other sensors that allow it to fly autonomously and precisely target specific areas of the field. The 50L sprayer drone is a highly efficient and cost-effective solution for farmers looking to improve their crop yields and reduce the amount of manual labor required for spraying.

Agriculture is an industry that has been revolutionized by technology over the years. The latest innovation in this field is the use of agricultural sprayer drone. These drones have become an essential tool for farmers as they help to improve crop yield while reducing the amount of time and resources required for traditional methods of spraying. Agricultural spraying drones are equipped with a spray system that can be used to apply pesticides, herbicides, and fertilizers. The drones can be programmed to fly over a specific area and spray the crops evenly, ensuring that all plants receive the required amount of treatment. This method of spraying is more efficient than traditional methods as it reduces the risk of under or over-spraying. One of the main advantages of agricultural spraying drones is that they are faster and more efficient than traditional methods of spraying. A drone can cover a large area in a short amount of time, reducing the amount of labor required for spraying. This, in turn, reduces the cost of labor and the overall cost of production. Another advantage of agricultural spraying drones is that they are more precise than traditional methods of spraying. The drones can be programmed to spray only the areas that require treatment, reducing the amount of chemicals used and minimizing the risk of environmental damage. This precision also helps to reduce the risk of crop damage, which can occur when chemicals are over-sprayed. Agricultural spraying drones are also safer for farmers and the environment. Traditional methods of spraying require farmers to be in close proximity to the chemicals, which can be harmful to their health. With agricultural spraying drones, farmers can operate the drones from a safe distance, reducing the risk of exposure to harmful chemicals. Additionally, the precision of the drones helps to reduce the amount of chemicals that end up in the environment, reducing the risk of pollution. In conclusion, the application of agricultural spraying drones in agriculture has revolutionized the way farmers approach crop management. These drones are faster, more efficient, and more precise than traditional methods of spraying. They also reduce the risk of crop damage, minimize the amount of chemicals used, and are safer for farmers and the environment. As technology continues to evolve, it is likely that we will see even more innovative solutions that will help farmers to improve crop yield and reduce the cost of production.

The agriculture drone is composed of drone platform, power system, control system and spraying system. The drone platform refers to the entire fuselage, which provides the basic frame of the aircraft and carries various accessories. The power system is composed of motors, electronic governors, propellers, batteries, and chargers, which provides the power for the entire drone to fly. The control system is composed of a display system and an operating system. In the display system, the communication equipment transmits various information such as the aircraft's altitude, speed, power, attitude, and position to the ground, and the ground operator can use the information provided by the display system to manipulate. The spraying system consists of a water tank, a water pump, a flow meter, sprinklers, etc., through which the spraying task is completed. 1. Propellers 13. Front Obstacle Avoidance Radar 2.

You can think about it in two ways. On the one hand, your usage plot. If it's a patchy and discontinuous piece of land, you may need to stop and restart the drone for many times, then the small payload drone is more suitable. If it is a continuous large-scale land, it is more suitable for heavy payload drones, and its operation efficiency will be higher. On the other hand, pls consider the scope of application. If it is fruit tree planting, fertilization and seed sowing, then you need a heavy payload drone to ensure efficient and effective use. For ordinary field crop spraying, both small-load and large-load drones can be selected, but the spraying efficiency of large-load will be higher.

There are thousands of routes, and safety is the first priority. After the drone takes off and leaves the ground, once an accident occurs, the consequences are very serious. Please keep the following safety rules in mind: Keep people away from the work machine The take-off and landing site should choose a place with a wide field of view and flat terrain, the surrounding environment should be unobstructed, and the ground should be free of obvious raised rocks, ridges, tree stumps, etc., to ensure that there are no people or animals within the take-off and landing radius of 10 meters, and it is necessary to Set up safety work reminder signs. Personnel should stay away from the running machine, do not touch the rotating propeller with your body or other parts, and do not wear loose clothing when flying to avoid injury to the propeller. Make sure there is no one in the operating route area Before takeoff, make sure that no one enters the operating route to prevent accidental casualties. Make sure the obstacle avoidance radar is on Safety first, efficiency second, please be sure to turn on the obstacle avoidance radar when working to ensure the safety of the operation. windy not working Pay attention to the ambient wind speed during operation. If the ambient wind speed is above grade 4, it is strictly forbidden to continue flying operations. When the ambient wind speed is grade 3-4, it is recommended to reduce the load and fly, and the flight speed should be controlled within 4 m/s. Overload operation is strictly prohibited Overload flight is strictly prohibited. If the drone is flying with a larger load than the rated load, it will easily lead to insufficient flight power on the route and emergencies such as forced landing. In addition to the above precautions, drone operators should also follow the following eight no-fly principles: ①Do not fly over areas with people. ②Do not fly within 20 kilometers of the center of the airport. ③The aircraft does not fly within the range of the take-off and landing route. ④Do not fly in sensitive areas such as military and border areas. ⑤Do not fly in places where flying is expressly prohibited. ⑥ Aircraft that have potential safety hazards or are not fully prepared will not fly. ⑦If the mental state is not good or the weather is not good, you will not be able to fly. ⑧ Do not fly when basic skills have not been practiced and proficient, especially do not approach people.

During the peak period of agricultural drone operations, transportation and transfer are frequent, and safety issues cannot be ignored. When transporting the drone, be sure to refer to the following safe transport instructions for operation and take appropriate protection. Safety Precautions Before Shipping ①When loading and unloading the drone, it is best to wear protective gloves to prevent cuts from the propeller. ②Transportation vehicles should be equipped with fire extinguishers and other corresponding fire-fighting equipment for emergency treatment. ③ Before transportation, fix the drone, fuel overcharging station and smart battery to prevent being squeezed, bumped, and overturned during transportation. ④Do not wipe your mouth, face or eyes with your hands during transportation. After loading and unloading, wash your face and hands with soap or special detergent in time, and rinse your mouth with water. Safety precautions during transportation ①Good ventilation should be maintained during transportation, no fireworks, sun exposure, rain, and high temperature should be strictly prohibited during transportation. ②The fuel overcharging station must be in a shutdown state after the gasoline valve is closed, the generator is cooled down, and it can be transported. ③For the fuel overcharging station, tighten the fuel tank cap and turn off the fuel switch during short-distance transportation. During long-distance transportation, the gasoline in the fuel tank should be drained, and the oil bolt should be loosened to drain the oil in the crankcase. ④ During transportation, standard metal gasoline drums must be used for oil storage containers, and plastic drums are prohibited. Safety precautions after transportation ①When loading, unloading and handling operations, handle with care to prevent bumping, dragging, falling and other behaviors. ②After transportation, check whether the drone and related parts leak oil due to bumps, etc. If there is oil leakage, it should be cleaned in time. ③ Vehicles that have shipped agricultural drones should be thoroughly cleaned and disinfected to eliminate potential safety hazards.

Good battery maintenance habits can not only reduce accidents, but also prolong its service life. Keep the battery clean and avoid corrosion After each operation, wipe the battery surface and plug with a dry cloth to ensure that there are no pesticides and mud stains left, so as not to corrode and cover the battery plug, resulting in short circuit or poor contact of the battery. Handle with care to avoid battery damage Dropping or impacting the battery may cause deformation damage or short-circuit spontaneous combustion. Therefore, when using the battery, you must handle it with care, and do not lift the power cord of the battery to avoid damage to the battery caused by falling and impact. After the battery is removed, it should be placed neatly, and should not be stacked or placed obliquely, so as to prevent the battery socket from rubbing against dirt or stones, resulting in poor contact. Charge in the shade and keep it ventilated During battery charging and storage, avoid direct sunlight and try to be in a cool environment as much as possible. When using a water tank for water-cooled charging, it is forbidden to use turbid, acid and other liquids to soak the battery, and it is forbidden to use containers (buckets, basins, etc.) other than the Jifei Technology water cooling box. Do not over discharge the battery Battery overdischarge is also a common cause of high battery temperature. If the battery is over-discharged, the battery will be damaged and the service life will be shortened. Aircraft modification and overloading can also lead to over-discharge of batteries. Regular inspection, do not disassemble the battery at will Regularly check the battery body, handle, wire, and power plug to see if the appearance is damaged, deformed, corroded, discolored, broken, and whether the plug is too loosely connected to the aircraft. In addition, non-professionals should not disassemble or install the battery at will, because improper operation can easily damage the circuit board, which may cause a fire.

Safety Precautions Before Working ①Check around the fuselage to ensure that all parts of the equipment, especially the key parts of the operation, are in good technical condition, the hardware installation is correct, safe and firm, the body, propellers and batteries are not damaged, and there is no inflammable and explosive objects mounted, If any abnormality is found, immediately stop using it for self-examination and maintenance. If you cannot solve it by yourself, contact the security personnel in time. ② Please check the drone firmware and APP version before operation. If the version is updated, please upgrade to the latest version, and please remove the propeller during the upgrade process. If the upgrade fails, please be sure to contact the corresponding security personnel to ensure that the upgrade is successful before use. ③ Pay attention to medication safety and personal protection. Please wear protective gloves when dispensing the medicine. If the medicine is accidentally splashed into the eyes, it should be washed with plenty of water in time. If you feel unwell, you should stop working immediately and seek medical attention in time. Safety precautions when working ①When using the fuel supercharging station to charge the battery, you can use the water cooling box to dissipate heat. At the same time, it is forbidden to shake the plug back and forth when pulling out the battery plug to avoid damage to the battery plug and socket. ②When the battery is charged and replaced and reinstalled, please keep the battery interface clean and tidy, free from dust, dirt and other dirt, to avoid the occurrence of bad battery contact, increased resistance, and battery heating alarm. ③ During the operation, pay close attention to the operation data and the flight status of the UAV, so that emergency control can be made in time in the event of an accident. Safety precautions after working ① Collect waste pesticide packaging and clean sewage in a centralized manner, and dispose of it rationally to avoid poisoning caused by inhalation of pesticides. ②After the operation, the drone should be cleaned and maintained, and the inside of the medicine box should be cleaned with soapy water or soap powder water to avoid damage to the equipment caused by pesticide residues.

For spraying medicine, many farmers have a habit of misunderstanding, that is, the more spray the better, it is best to be able to soak it all like a bath. In fact, doing so not only increases costs and reduces efficiency, but also produces phytotoxicity and pesticide residues, pollutes the environment, and causes soil agglomeration. For some specific crops and specific agricultural links, more precise application of pesticides is required, such as cotton chemical control and rice weeding. The precise control of the dose in these links is very strict. Heavy spraying and multiple spraying will cause phytotoxicity; missed spraying and less spraying will not achieve the control effect. Both of these affect the output quality and yield of the crop. The plant protection drone atomizes the high-concentration medicinal liquid to make the medicinal liquid evenly dispersed and attached to the surface of the crop, and the accuracy of the atomization is relatively high. At the same time, different spraying scenarios have different requirements for the size of atomized particles, and traditional pressure nozzles cannot independently and accurately control the flow rate and atomized particles, making it difficult to achieve true accurate spraying. YJTech UAV is equipped with centrifugal variable atomization spraying system, which opens the era of precise operation of plant protection UAV. The precise spraying effect of agricultural drones is once again improved.

In particular, pay attention to the plots that have been mapped in previous years, and whether the information has changed, such as whether the marked trees have grown up, or the obstacles are different. When surveying and mapping, pay attention to the branches on the side of the plot, and survey and map the outermost 1 meter of the branches. Some fruit trees may have a higher and wider crown after one year's growth, and they need to be marked again. When surveying and mapping the wire, the lowest point of the entire horizontal cable should be measured, and the flight should be carried out at a height lower than the lowest point of the wire. If there are many wires and staggered, you can use functions such as block cutting to further reduce the occurrence of frying. Generally, the surveying and mapping should surround the entire obstacle, and the utility pole and the cable stay should be surveyed and mapped as one obstacle. Do not fly through the middle of the cable and the pole.

After the completion of the operation, the maintenance we need to carry out on the equipment mainly includes several modules such as the body structure, the battery and the overcharge station. In general, not only after each operation, you need to simply clean your equipment, check whether there are loose parts, whether there are debris infiltrated, whether the interface is corroded, but also need to develop good regular maintenance. Habits can prolong the life of the equipment.

Before each operation, a pre-flight inspection should be carried out on the equipment. Doing a good job in the pre-flight inspection is of great significance to prevent flight abnormalities. However, if any problems are found during the inspection process, the operation should not be carried out. 01 The pre-flight inspection is divided into several major parts, including inspection of the airframe itself, App and firmware update, power system test, positioning system inspection, and inspection of the take-off environment before take-off. 02 Regarding the airframe itself, basic maintenance tools can be used to start the pre-flight inspection, mainly including flight structural components, power system, spray system, positioning system, obstacle avoidance system, and ground imitation system. 03 It should be noted that there is no excessive bending of the feeder, and that RTK-L and RTK-R are not reversed. 04 Focus on checking whether the buckles of the execution system and the flight system are tight. 05 Check the appearance of the equipment mainly to see if the propeller is damaged, the arm and the fuselage are cracked. Whenever the propeller is cracked or otherwise damaged, it should be replaced as a whole.

In the event of abnormal flying of agricultural drones, you should first keep calm to ensure the safety of on-site personnel. In emergencies, hover the drone first, and then do other operations. 01 The agricultural drone can be hovered by short pressing the middle button through the App interface or directly on the one-hand control. 02 After hovering, operations that can be performed on the app include landing, returning home, adjusting the working height, adjusting the working speed, turning on or off the imitation, and turning on or off obstacle avoidance. 03 After hovering, the operations that can be performed with one-hand control include moving the agricultural drone forward and backward, left and right, rotating clockwise and counterclockwise, and returning to home.

In this epidemic prevention and control battle, drones have also become popular again. At present, drones have been widely used in transportation, surveying and mapping, film and television, leisure, plant protection and many other fields. Chinese plant protection drones eyeing the Japanese market In various application fields, agricultural plant protection is a high-profile commercialization scenario for drones. Driven by the dual dividends of policy and market, China's plant protection drone industry has developed rapidly, and many plant protection drone companies have turned their attention to foreign countries. Japan and my country are separated by a strip of water, facing each other across the sea, with similar geographical locations, as well as the practical conditions and historical accumulation of the application of plant protection drones, and have become the first choice for Chinese enterprises to go overseas. Of course, another important reason is that Japan's population aging trend is becoming more and more prominent, and the agricultural labor force continues to decline, resulting in insufficient agricultural population and increasing demand for agricultural drones and intelligent equipment. On the other hand, the area of arable land in Japan is also shrinking, and it is imminent to increase agricultural output. Therefore, Japan has been vigorously promoting the process of agricultural modernization, and the use of automated machinery is more popular than my country, and the use of plant protection drones has also been used for a long time. However, the development of Japanese plant protection drone products is relatively slow, and it is no longer comparable to Chinese products in terms of automation and intelligence. It was difficult for China to import Japanese plant protection drones Although the current Chinese plant protection drone products have achieved a counterattack, they are preparing to "enter" Japan. But more than ten years ago, when China's domestic plant protection drone industry was still blank, Japan already had a relatively complete drone industry chain and had great advantages in the field of plant protection drones. In 2006, there was also a turmoil between China and Japan caused by drones for plant protection. At that time, Chinese companies wanted to buy a plant protection unmanned helicopter produced by Yamaha, but the Japanese government repeatedly blocked it. Nagoya Customs seized a Yamaha unmanned helicopter that was going to be exported to China. The reason given by the Japanese side is that the export of the drone is not complete, and this unmanned helicopter may be diverted for military use. Yamaha responded that they were exporting unmanned helicopters for pesticide spraying to China, which cannot fly autonomously and are not on the monitoring list. In fact, according to relevant media, the payload of the seized UAV is only about 20 kilograms, which is far from meeting the requirement of the Japanese government that "the payload of unmanned helicopters for export shall not exceed 300 kilograms". China's civil drone industry has risen in an all-round way After more than ten years of hard work and accumulation, China's civil drone industry has risen in an all-round way, vigorously developed mature multi-rotor drone technology, and made great progress in the field of plant protection drones, surpassing its Japanese counterparts. China's advantages in the field of civilian drones have attracted the attention of Japan. Recently, the Japanese cabinet passed a new bill, stating that it will actively promote the development of 5G and drone technology in the country, and eligible Japan will be expected to receive low-interest loans from government-affiliated financial institutions. In addition, Japanese companies are also actively seeking cooperation with Chinese companies. In 2019, Blue innovation, a Japanese company developing a drone application system, cooperated with Xunyi, a Chinese logistics drone company. Although we have achieved gratifying achievements in the field of drones, we must not be complacent. After all, the road ahead is difficult, and there are still many challenges waiting for Chinese drone companies to overcome. Looking at the industry as a whole, Weilai's global civilian drones are still optimistic. With the upgrade of intelligent technology and the integrated application of 5G networks, the application of drones in consumer and industrial scenarios will become more diversified. Research institutions predict that by 2020, the drone market will reach $100 billion.

According to the Civil Aviation Administration of China, as of the end of 2020, there were 523,600 drones registered across the industry in China, which means that compared with 392,000 at the end of 2019, a year-on-year increase of more than 33%. According to statistics, in 2020, China's drone commercial flight activities will be 1.594 million flight hours, a year-on-year increase of 36.4%. With the acceleration of the 5G tide in the civilian drone market, the industry's prosperity has risen. "5G + Industrial Internet" has created a new growth space for industrial drones, and 5G features such as low latency create a new growth space for the consumer drone market. In terms of industrial drones, industrial drones are currently mainly used in agricultural plant protection; in terms of consumer drones, the global market shows a clear trend of head concentration. According to data released by Gartner, the output value of the drone industry will exceed 400 billion US dollars in the next 10 years.

Agricultural plant protection UAV is a new type of agricultural machinery used in agricultural spraying and sowing. It can not only ensure the production safety of crops, but also improve the utilization rate of pesticides, which is conducive to the realization of the goal of reducing the amount of pesticides used and reducing pollution. The significant advantages of plant protection drone operations have led to a rapid increase in the global population. However, some users operate plant protection drones illegally, which not only has serious safety hazards, but also has a bad impact on the entire aviation plant protection industry. Here, YJTech drones reminds all plant protection drone operators: 1. Ensure that the plant protection drone maintains a safe distance of more than 6 meters from people during the use of the plant protection drone. Any form of manned operation of the plant protection drone is prohibited. 2. Do not use plant protection drones for operations other than agricultural plant protection. 3. Do not get close to the plant protection drone in flight, and avoid touching the rotating propeller. It is hoped that all aviation plant protection practitioners use plant protection drones in a scientific and standardized manner to jointly create a good plant protection operating environment and ensure the safety of agricultural mechanized production.
