Thus, the problems of the measuring, collecting and converting of agricultural wind speed into triboelectricity quantity and convenient storage can be solved. The hemispherical fan blade of a wind speed sensor can be pushed to rotate by wind energy, and the sleeve of the wind speed sensor can rotate, so that the following rotation of a blade disc can be realized, and rotating contact with a disc base plate opposite to and in contact with the blade disc can be generated during rotation; the surface, opposite to the disc base plate, of the blade disc is provided with electrodes;one electrode is covered with a friction material, and one electrode is grown with a nanoscale metal oxide; and the rotating contact can cause the rotation, contact and friction of the friction material and the nanoscale metal oxide, so that the wind energy can drive the material to generate electricity through friction, and effects of electric energy storage and wind speed measuring can be realized.

Description

technical field [0001] The invention belongs to the fields of agricultural intelligence and environmental protection, and relates to a nano-friction electricity generation method of a self-driven agricultural internet of things wind speed sensor. Background technique [0002] In addition to natural light, heat, water, and air that are beneficial to agricultural production, wind is also one of the environmental factors of agricultural production. Normal wind is very effective for agricultural production, and moderate wind speed plays an important role in improving the environmental conditions of farmland. So measuring wind speed and direction will be of great help to agriculture. Therefore, it is necessary to monitor the wind speed in a timely manner. The sensors used for monitoring today are mainly wind speed sensors based on the principle of heat transfer or differential pressure. They are important equipment for wind parameter measurement in agricultural climate automatic ...

AI Technical Summary

Problems solved by technology

[0008] In order to solve the problem of measuring agricultural wind speed and collecting it and converting it into frictional electricity for easy storage, the electricity for wind speed detection comes from the measurement itself. The AC signals of different frequencies generated by the nano friction generator can measure and calculate the wind speed, and can store the electric energy to supply power for other sensors, thus solving the problem of self-power supply or self-drive of the sensor system
