Abstract

The invention provides a soil humidity monitoring method and device based on a micro cantilever beam, equipment and a medium. The method comprises the following steps: detecting a state of a piezoelectric micro cantilever beam, and recording an initial resonance frequency of the piezoelectric micro cantilever beam; detecting the state of the piezoelectric micro cantilever beam in real time, when water molecules are detected to be attached to the piezoelectric micro cantilever beam, acquiring data of the piezoelectric micro cantilever beam, and calculating a resonant frequency of the piezoelectric micro cantilever beam according to a vibration equation of the piezoelectric micro cantilever beam; and calculating a resonant frequency variation of the piezoelectric micro cantilever beam according to the resonant frequency of the piezoelectric micro cantilever beam and the initial resonant frequency, and analyzing soil humidity according to the resonant frequency variation. In the invention, the piezoelectric micro cantilever beam is coated with a coating for measuring the water molecules, and the water molecules are attached to the piezoelectric micro cantilever beam so that the piezoelectric micro cantilever beam generates vibration, and the humidity of soil is analyzed according to a change amount of the resonance frequency. In this way, the water molecules are counted, and the soil humidity can be measured more accurately.

Description

technical field [0001] The invention relates to the technical field of soil detection, in particular to a soil moisture monitoring method, device, equipment and medium based on a micro-cantilever beam. Background technique [0002] Soil moisture is the soil water content. When observing the profile in the field, the degree of soil moisture is distinguished. It is generally measured by dry, slightly moist, moist, damp and wet. Soil moisture is an important environmental factor connecting the water resources inside. Soil Humidity has an important impact on hydrology, meteorology, and agricultural production, so how to measure soil moisture has become the focus of research in recent years. [0003] The existing soil measurement technology uses wireless sensors to measure the soil humidity, but the existing technology still has the following defects. Due to the large area of ​​soil detection, the amount of data generated by wireless sensor detection is too large, and the system ...
