Description
Technical Field
The utility model belongs to the technical field of furniture, especially, relate to a mechanical type soil parameter monitoring devices.
Background
In the agricultural planting industry, the quality of the plant growth environment directly affects the growth condition of plants, and the real-time monitoring of the plant growth environment is particularly important. The soil contains a proper amount of water which is a basic condition for plant growth, and soil water measurement is also an important technical means for realizing water conservation, drought resistance, soil moisture detection and quantitative irrigation, so that the real-time rapid monitoring of the soil water becomes one of the key technologies in the field of precise agricultural planting. At present, the detection method of soil humidity (soil water content) mainly comprises a time domain reflection method (TDR), a frequency domain reflection method (FDR) and a standing wave rate method (SWR). The TDR technique implements measurement of soil humidity by measuring propagation time of electromagnetic waves in soil emitted from a probe inserted into soil, the FDR technique analyzes soil humidity by sensing conduction and attenuation of electromagnetic waves in soil by the probe, and the SWR technique senses soil impedance by a standing wave shape of electromagnetic waves on a transmission line and further obtains soil humidity. The TDR soil moisture measuring instrument can realize real-time measurement and high precision, but the TDR relates to high-speed electric signal analysis, and the technology is mainly monopolized by Europe and America, and the realization difficulty is big, and the price is expensive, for example, one set of TDR measuring instrument imported from America is about 2 ten thousand dollars in price. FDR technology, although somewhat simpler than TDR, is currently also heavily imported domestically and therefore also costs thousands of dollars. The SWR technology is relatively simple to realize, can meet requirements for scientific research application and small-batch test points, but the price of the SWR technology is still not suitable for large-scale popularization, and SWR products in the current market cannot work independently and often need to be matched with an external system for use to obtain a measurement result.
The DZN2 type soil moisture detector utilizes FDR principle to calculate the moisture content of the object to be measured according to the difference of radio frequency of the electromagnetic wave emitted by the detector in the substances with different dielectric constants. The instrument is widely used for measuring the volume water content of various types of soil so as to reasonably arrange irrigation and save water resources. DZN2 type soil moisture detector includes the detector body, and the detector body top-down sets gradually a plurality of sensor node, and every sensor node sets up the moisture information that frequency acquisition unit is used for gathering soil.
As a test instrument, the DZN2 type soil moisture detector should be calibrated every two years. The traditional soil moisture detector calibration method is that a tester connects a soil moisture detector with computer calibration software, and then inserts the soil moisture detector into four standard soil boxes with different water contents by hands to respectively read data. When the detection method is used for detecting the DZN2 type soil moisture detector, a plurality of sensor nodes in the DZN2 type soil moisture detector are respectively inserted into four standard soil boxes with different water contents by hands, and the defects of large workload and low working efficiency exist.
