Abstract: The tea garden anti-frost machine is a kind of machinery that can effectively deal with the frost damage of the young tea leaves caused by the cold in the early spring of the tea garden. The traditional tea garden anti-frost machine uses diesel generators as power, and the daily shelving time is long. Today, when fossil fuels are increasingly scarce, continue The use of fossil fuels not only increases the investment of tea farmers, but also destroys the atmospheric environment and reduces the quality of tea. To address this issue, this paper uses wind-solar hybrid technology to replace fancy fuels to provide power for anti-frost fans. While solving the energy problem, an automatic start-stop device for the anti-frost machine under certain conditions was designed using PLC and touch screen. After field tests, it was found that the use of the wind-solar complementary intelligent tea garden anti-frost system can significantly improve the tea garden environment and the quality of tea leaves, saving tea farmers and creating economic benefits.
