Embodiment

[0036] further as Figure 4 As shown, the apparent dielectric constant (ε) of the soil is measured according to the propagation frequency of the electromagnetic wave in the medium by using the principle of electromagnetic pulse, so as to obtain the volumetric water content of the soil. Among them, the same pair of probe copper rings 1 form the two electrodes of the capacitor up and down, the middle is an insulating material, and the soil is used as the capacitor medium on both sides. At this time, a high-frequency electromagnetic pulse signal is passed to the capacitor, and the electromagnetic pulse propagates in the soil. The dielectric constant will affect the frequency of propagation, so the moisture content of the soil can be determined by detecting the frequency of high-frequency signal propagation in the soil.

[0037] Such as Figure 5 As shown, firstly, the copper ring 1 of the probe acts as the capacitive element of the LC resonant circuit of the high-frequency oscil...

Abstract

The invention belongs to the technical field of soil moisture analysis and specifically discloses a soil moisture content acquisition device and its operating method. The soil moisture content acquisition device comprises a probe, an insulating rod, a PVC insulating tube, an antenna, a tapered plug, a coaxial cable and a top cover. According to the soil moisture content acquisition device and its operating method, on one hand, the device is reasonably designed, has a compact structure, has a wide range of application and can rapidly and accurately acquire soil moisture information and error is small; and on the other hand, the device can remotely collect and monitor soil moisture information and is convenient to use, and soil moisture information acquisition and management invested costs are reduced. Meanwhile, production costs are low and the device is easy to popularize.

Description

technical field [0001] The invention belongs to the technical field of soil moisture analysis, and in particular relates to a soil moisture collection device and a working method thereof. Background technique [0002] Moisture refers to the humidity of the soil suitable for plant growth and development. Moisture, refers to the soil moisture, soil moisture is the dryness of the soil, that is, the actual water content of the soil. Soil water is the main source for plants to absorb water (except for hydroponic plants). In addition, plants can also directly absorb a small amount of water that falls on the leaves. The main source of soil water is precipitation and irrigation water, among which the plant roots interspersed in the soil pores Absorb water from water-bearing soil pores for growth and development. Therefore, monitoring and analyzing soil moisture content is an important indicator of agricultural production (whether irrigation can be analyzed according to the situati...
