Problems solved by technology
[0002] The complex and changeable environmental factors of the mountain environment will seriously affect the stability and reliability of wireless signal transmission. The joint influence of vegetation density, rainfall and many other factors will affect the wireless information transmission success rate of orchard wireless monitoring system, orchard unmanned plant protection machinery, and orchard unmanned aerial vehicle
[0003] At present, in terms of effective transmission of wireless signals in orchards, the main methods currently used are mainly to solve the problem from the perspective of increasing the transmission power of wireless devices or reducing the transmission distance between wireless devices, but this will reduce the working life of wireless devices in orchards. Or more wireless devices need to be used for coverage, and there is a lack of a power control method for improving the wireless transmission performance of mountain orchards that can extend the working hours of wireless devices and improve the coverage of wireless devices, so as to meet the complex and changeable environment. The need for wireless signal transmission in orchards
