In the major pest and disease prevention and control work programs issued by relevant departments in the past two years, it has clearly proposed to use modern technology to strengthen monitoring and early warning of pests and diseases, so as to improve the technical level of pest monitoring and early warning, determine the best period of prevention and control, and reduce major Loss of pests and diseases. At present, information technology has become an important force to improve the prevention and control of agricultural and forestry pests and diseases, and plays an important role in the process of modern development of green plant protection and public plant protection.

To carry out pest and disease monitoring and early warning, the important work content is to collect and timely feedback the information of pests and diseases. The common type of insect detection and reporting lamps used in the past need to go to the scene to obtain the information about the insects collected by the system, and the real-time performance is not strong. The remote camera type insect detection light is different. It can not only automatically complete the system operation of attracting insects, insects and mobile phones, but also use the high-definition camera to shoot the insect images and wirelessly transmit them to the information platform. In this way, the plant protection The personnel can remotely grasp and analyze the dynamic changes of the insect situation, timely guide scientific prevention and control, and strictly control the pests and diseases.

The remote camera-like insect detection lamp is an automated and intelligent system dedicated to insect reporting, which effectively solves the problems of obsolete equipment, few grassroots people, lack of transportation, and inconvenience in investigation. It has achieved system monitoring and timely forecasting. Scientific prevention and control provides a reliable guarantee for accurate monitoring and early warning of pest sciences, and effectively reduces the loss of biological disasters, which helps to do a good job in agricultural safety production.

In the critical period of pests and diseases, the Internet of Things system such as remote photo-type pest detection and reporting lights has been escorted. Farmers have carried out pest control work in a timely manner, and they are targeted in a timely manner, which not only has good control effect, but also significantly reduces pesticide use. The quantity has reduced the cost of prevention and control, improved the quality and safety of agricultural products, and provided strong support and solid guarantee for deepening the structural reform of the agricultural supply side and implementing the rural revitalization strategy.

LED Streetlight

Led street light, compared with the traditional lighting technology, led lamps and lanterns have higher efficiency, and longer service life.Thus become the preferred bulb type, in order to reduce the energy consumption of indoor/outdoor lighting, get energy saving effect.
For street lamps, higher efficiency and longer life are indispensable for cost reduction.Designed for the LED power supply switch power supply, also must have a high efficiency and durability, to ensure that it has as long as the LED life without maintenance.Here, the resonant converter is one of the most popular power supply topology, this is because compared with previous power supply topology, their performance has brought higher power efficiency, and can reduce EMI.Soft switch is an important characteristic of resonant converter.But the resonant converter used in parasitic diodes (bodydiode) can sometimes lead to system failure.Stored in the parasitic diodes charge must be clear, to avoid large current and voltage surge, including topology structure of high dv/dt and di/dt.
