Application of UAV Remote Sensing Technology in the Construction of Modern Smart Farm

Abstract

This article is to study the application and optimization of UAV remote sensing technology in the construction of smart farms. Multiparty calculations, circuit design, remote sensing, and remote control are used wirelessly, with a wide field of vision and easy evasion. Its transmitting frequency, transmitting power, interference electromagnetic wave intensity, receiving sensitivity, and gain coefficient are all factors that affect wireless remote sensing. Stress and strain are also important factors for the timely response and control of remote sensing technology. This article first outlines smart farms and drones, and then describes how to design drone circuits. Its smallest UAV circuit design includes UAV reset circuit, UAV crystal oscillator circuit, UAV upgrade circuit, UAV PPM decoding module circuit diagram, and then explains the attitude calculation and complementary filtering of the multiwing UAV. The complementary filtering algorithm is applied to the attitude calculation, and the error is reduced through the analysis of the coordinate system, the quaternion method, and the calculation of Euler angles. Then establish a wireless communication propagation model for smart farmland monitoring. Among them, the Egli model is selected. After data monitoring, it is obvious that the Egli model can monitor higher path loss, higher accuracy, and stronger propagation strength. Then through experiments, the static data of the two different tail transmissions under different loads are analyzed, the stress-strain trend line is observed, and the performance of the two transmission systems is analyzed. It can be seen that under the same conditions, the bevel gear tail transmission system has higher comprehensive performance, good reaction force characteristics, and excellent stress-strain performance. The power ratio of the synchronous belt tail drive system is 31.22, and the power ratio of the bevel gear is 29.52, a difference of 5.76%. The power ratio wind speed value of the tail part of the timing belt is 0.01014, and the power ratio wind speed value of the bevel gear is 0.009851, a difference of 2.93%.
