Color Sorter is a highly efficient automated device widely used in food processing, mining, and chemicals to ensure product quality. Its working principle can be divided into the following key steps:

1. Feeding System: The materials to be sorted are delivered to the feed inlet via a conveyor belt. The feeding device starts vibrating, spreading the material evenly on the feed chute. Under the action of the vibrating chute, the material automatically forms a continuous linear arrangement and enters the photoelectric detection system at a constant speed.

2. Photoelectric Detection System: The machine is equipped with an LED light source inside, providing stable and uniform illumination for the material to ensure the most accurate color is displayed during detection. High-resolution cameras and sensors capture images of the material under specific lighting and send them to the image processing center for identification.

3. Image Processing System: The acquired images are transmitted to the control system. Hawit’s independently developed algorithm analyzes the color, shape, and size characteristics of each object. Using this algorithm, the system compares the material's features with preset standards (such as color differences between qualified and defective products) to quickly identify the materials that need to be removed.

4. Execution System: Once defective material is detected, high-pressure air valves control the opening and closing of high-pressure gas according to preset instructions. The air nozzles then blow the non-compliant material into the waste bin.

5. Output System: After processing, the finished products and waste are separately sorted into different discharge outlets, ensuring efficient sorting is achieved.

Drone spraying is a new type of operation method in technological development. High work efficiency, suitable for large-scale agricultural pest control. This is tens or hundreds of times more than physical labor. It can complete tasks that are easy to manually complete, such as forest and mountain forest operations. So how effective are unmanned aerial vehicles used for medicinal purposes on rural land?

Things often have two sides, namely advantages and disadvantages. Drone spraying is no exception, each with its own advantages and disadvantages. The advantage is that the spraying speed is fast. The crop protection drones used for agricultural spraying are generally multi rotor aircraft, much larger than typical small aerial photography drones, with longer endurance and much faster speed. Not to mention, compared to manual spraying, the spraying efficiency of aircraft is hundreds of times higher.

In addition, crop protection drones can adopt two control methods: manual remote control and satellite guided control. Usually, large plots use satellite navigation to control spraying. For land parcels, seamless spraying can be achieved without losing crops. No matter how slow and careful manual spraying is, there will always be omissions at the beginning, which machines cannot match

The spraying quality is also very high. The principle of drone spraying is to install the medicine box on the body of the drone, open the valve after the drone takes off to discharge the medicine, and then use the strong wind generated by the high-speed rotation of the drone blades to atomize and blow down the medicine. Due to the strong atomization and falling of drugs by the wind, the adhesion and diffusion rate of drugs is higher than traditional manual spraying, so the effect of spraying drugs in this way is higher than manual spraying.

In fact, there are many potential safety hazards hidden in drones, and some issues have also been documented in previous reports. For example, during the process of spraying pesticides, if no pesticides are sprayed into the river, all organisms in the river will be poisoned. A clear river on the horizon is easily destroyed. If there are artificially cultivated aquatic products in the Tianbian River, it is easy to become an economic dispute if such a problem is encountered.

In addition, the promotion of drone pesticide spraying in modern rural areas is insufficient, and there are many regulatory loopholes. Relevant departments need to introduce policies to guide and manage it correctly, avoid irreparable losses caused by technical errors, and ensure the safety of drone pesticide spraying.

Therefore, if rural areas want to implement drone pesticide spraying, corresponding technical support must be provided first, and drone training must be provided to farmers to ensure that they use drones in the correct situations, thereby avoiding many problems. As long as they have sufficient technology, they must maintain consistency in the spraying process.

In addition, due to its fast speed, the effect of uniform application is poor. The drone spray passes through instantly, making it difficult to mix evenly and thoroughly. The only way to overcome the problem of uneven and thorough beating is to increase the concentration of the liquid medicine, thereby increasing the investment cost. For example, when spraying drugs in cotton fields, UAV spray can not kill cotton bollworm in cotton buds, aphids on the back and bottom of leaves.

Only by absorbing crops can endogenous pests be dealt with, and some pests may not be killed by endogenous agents but can only be dealt with through contact. The main disadvantage of manual spraying is slow speed, making it difficult to spray at high altitudes. It has the advantage of uniform application, which can evenly and thoroughly hit crops up and down. Save technical solutions.

Although there are many advantages to using drones to spray pesticides, such as high efficiency and good quality, there are also certain limitations. For example, it depends on weather conditions. It cannot take off in bad weather and cannot work all day. It is only suitable for the vast northern regions, while the southern mountainous and hilly areas are not particularly suitable for large-scale operations.

Generally speaking, using drones to spray pesticides on farmland is very cost-effective. Short time, uniform spraying, and affordable price. Therefore, more and more farmers are gradually choosing to use drones to spray pesticides on crops. There are also many smart young people who see the vast prospects of this industry, specializing in drone spraying, and the profits are still considerable.

Drones are a manifestation of high-tech technology applied in agriculture, and are a progressive product of the combination of modern technology and traditional agriculture. From an efficiency perspective, it is indeed higher than manual spraying. From a practical perspective, it cannot be compared to manual operation. Drones can only spray on the front of crops, but cannot spray on the back of crops.

When spraying pesticides, unmanned aerial vehicles also pay attention to the weather. Due to strong winds and heavy fog, it is impossible to operate, and manual operation can completely ignore this situation. Therefore, unmanned operation has its own advantages, and manual operation also has its advantages, which should be complementary. We cannot veto drones with one vote. We should view new things from a developmental perspective. Although there are drawbacks to drone operation, it is an assistant for the future development of agriculture.

The development process of agricultural drones can be divided into several important stages, each with its unique characteristics and milestones. ‌

Future trend: Plant protection drones will further become intelligent and precise, improving operational efficiency and effectiveness while reducing costs and meeting the diverse needs of farmers.

Technological progress and market application

The development of crop protection drone technology is also accompanied by the continuous expansion of the market. Abroad, Japan developed the world's first crop protection drone in 1987 and currently has over 5000 in stock. Since 2004, China has been researching and promoting unmanned aerial vehicles (UAVs) for crop protection. By 2019, the number of UAVs in operation had reached 55000, covering an area of 33 million hectares. The advancement of policies and technology has also driven the rapid development of crop protection drones in China.

Key technologies and market acceptance

The key technologies of crop protection drones include power systems, flight control, and spraying systems. In the early days, it was mainly oil powered aircraft, but with the rise of electric drones, electric drones gradually became the mainstream in the market due to their cost-effectiveness and environmental friendliness. In terms of market acceptance, farmers have gradually shifted from a wait-and-see attitude to acceptance and recognition, and crop protection drones have become an indispensable tool in agricultural production.

High voltage transformer is a type of electrical equipment mainly used to convert voltage from the high voltage end to the low voltage end. It is mainly composed of iron core and winding. The iron core is made of highly magnetic conductive material to provide a strong magnetic circuit, while the winding is used to carry current and generate a magnetic field. The following is a brief introduction to the working principle, operation, and maintenance of high-voltage transformers.

1. Working principle:

High voltage transformers work using the principle of electromagnetic induction. When a high-voltage power supply is connected to one side of the winding, current flows through the winding, generating a magnetic field. The magnetic field passes through the iron core and then senses along the winding on the other side. According to Faraday's law, when the magnetic flux changes on the other winding, an induced electromotive force is generated. According to the winding ratio, the induced electromotive force will change the voltage at the output terminal.

2. Running process:

During operation, high-voltage transformers rely on external power sources to provide electrical energy. The voltage of the high-voltage power supply is connected to a high-voltage winding, while the low-voltage winding is connected to the equipment that uses electrical energy. When an external power source is powered on, high voltage current passes through the high voltage winding, forming a magnetic field. The magnetic field passes through the iron core and induces the voltage on the low-voltage winding. In this way, the voltage of the high-voltage power supply will be converted into low-voltage voltage and supplied to the equipment in use.

3. Maintenance:

In order to maintain the normal operation of high-voltage transformers and extend their lifespan, the following points need to be noted:

-Regularly inspect the windings and iron cores for damage, corrosion, or looseness. If there are any problems, they need to be repaired or replaced in a timely manner.

-Check the insulation status of the winding to ensure that the insulation is intact. If insulation damage is found, it must be repaired in a timely manner.

-Clean and maintain the cleanliness of the surrounding environment of the transformer to prevent dust or impurities from entering the transformer and causing malfunctions.

-Regularly inspect and replace the insulation oil inside the transformer to ensure good quality of insulation oil and maintain stable insulation performance.

-Monitor the temperature and humidity of the transformer to ensure they are within the normal range. If the temperature is abnormally high or the humidity is too high, timely measures should be taken to adjust or repair it.

The above brief introduction to the working principle, operation, and maintenance of high-voltage transformers can help understand the basic principles and operating points of high-voltage transformers.

The onboard control system mainly includes flight control board, sensors, actuators, etc. The flight control board is the "brain" of the drone, responsible for processing information from sensors and calculating control commands. Sensors are responsible for collecting various status information of drones, such as attitude, speed, altitude, etc. The executing mechanism drives the various components of the drone to perform corresponding actions according to the instructions of the flight control board.

3. Control method of unmanned aerial vehicle

There are various control methods for drones, including manual control, automatic control, and hybrid control.

Manual control is the most direct control method, where operators issue commands through a remote control to control the flight of the drone. This method requires operators to have certain flying skills and experience, but can achieve high flexibility and real-time performance.

Automatic control is the use of pre-set programs or algorithms to enable drones to autonomously complete flight tasks. This method does not require manual intervention and can greatly improve the stability and efficiency of flight. For example, in the field of aerial photography, drones can automatically capture images through pre-set routes, greatly reducing the burden on operators.

Hybrid control is a combination of manual control and automatic control, which retains the flexibility of manual control while leveraging the stability advantage of automatic control. In practical applications, operators can flexibly choose control methods based on task requirements and environmental changes.
