Abstract
The utility model discloses a controller for inducing soil moisture, which comprises a control meter and a sensor which is connected with the control meter in signal mode, wherein the sensor is composed of an outer shell, a stainless steel probe arranged on the bottom portion of the outer shell, and a high-frequency oscillation detection circuit arranged in the outer shell, a micro-processing module is arranged in the control meter for processing all signals transmitted by the sensor, and the probe is a cone-type cone or a ring-type probe. Furthermore, the outer shell of the sensor is packaged by epoxy resin pure colloid with good sealing performance, thus the sensor can be directly buried in oil to use and ca not be corroded. Based on the FDR method of dielectric physics, the controller can measure soil moisture content by using reflections of high-frequency oscillation to different media. The controller can be widely applicable to fields such as water-saving agriculture irritation, tea garden drop irrigation and scientific experiments.
Description
Technical field
The utility model discloses a kind of controller that is used to respond to soil moisture humidity, belongs to soil moisture testing tool class manufacturing technology field.
Background technology
Soil moisture is a pacing items that cuts plant and grow, and it is one of the gordian technique in water conservancy, agricultural and the robotization of the row of filling and some other fields that the degree real-time of soil moisture is measured.This has been carried out a large amount of research both at home and abroad for a long time, successively proposed many kinds of assay methods, wherein utilizing soil dielectric property and its water cut to concern to come measured soil moisture is present research direction.Darker with researchs such as capacitance method, time domain reflectometry (TDR method), microwave methods again in these methods, but they all exist weak point separately.
After Canadian scholar Dr.Topp used TDR method measured soil moisture and proposes famous Topp formula, TDR measured soil moisture progressively became the main mode of soil moisture measurement.The TDR method is to measure electromagnetic wave is estimated soil along the transmission time that insertion contains water and soil soil probe water percentage.Because this technology relates to the high-speed electrical signals analysis, technology is very complicated, makes the instrument cost of this technology of employing also very high, and about 100,000 yuans, these have all greatly limited applying of this method.
CN101017133 discloses a kind of soil water measuring instrument based on infrared radiation, mainly by infrared emission circuit, photo-detector, red emission circuit and be placed on photo-detector and the pedotheque box in the middle of condenser system forms, different in moisture makes ground to the different principle of its degree of absorption when utilizing certain wavelength near infrared ray to shine testee.CN200968934 discloses a kind of name and has been called a kind of soil moisture sensor based on optical fiber surface plasmon resonance, by stainless steel filter cap, moisture-sensitive film, the Au film, the dome-type prism, optical fiber and moisture transducer probe are formed, and obtain the content of soil moisture from the spectral information of fiber reflection.Owing to adopted pure method of optics, thereby reduced the influence of soil types and soil particle size, improved the sensitivity and the degree of accuracy of moisture measurement measurement result, but complicated optical system and and supporting signal processing circuit be difficult to reduce cost.
Summary of the invention
At the deficiency of existing soil moisture measuring technology, the utility model provides a kind of rational in infrastructure, controller that is used to respond to soil moisture humidity that measuring accuracy is high.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of controller that is used to respond to soil moisture humidity, comprise controller and the sensor that is connected with its signal, wherein, described sensor is by shell, is arranged at the stainless steel probe of outer casing bottom and is located at the higher-order of oscillation testing circuit of enclosure, establish a micro treatment module in the controller, be used for each signal that processes sensor transports, described probe is bevel-type probe or ring type probe.
Further, the shell of described sensor encapsulates with the pure colloid of epoxy resin, good airproof performance, and the middle use of can directly placing into the soil is not corroded.
Further, described probe is center probe and the probe that is arranged at its all side, each detachable bottom that is connected in sensor outer housing of popping one's head in.
After sensor probe inserted soil, each probe contacted with different medium in the soil, when when soil moisture changes, the signal that corresponding probe is collected back also changes thereupon, by the parsing of high-frequency detection circuit, be sent to the control panel of controller, transfer by last water level knob and go up the water level start; By water level shutdown under the water level knob is transferred down.The utility model utilizes the reflected measurement soil water content of the higher-order of oscillation to different medium based on the FDR method of dielectric physics.
The utility model can be widely used in fields such as water-saving agriculture irrigation, tea place drip irrigation, scientific experiment.
