Problems solved by technology
The detection results of the traditional chemical analysis method are accurate and reliable, but the detection speed is slow and the detection cost is high, which requires professionals to carry out the detection in the laboratory; the remote sensing measurement method has large measurement errors due to geographical and spatial uncertainties, and cannot Realize accurate measurement; although near-infrared spectroscopy can detect the content of total carbon, total nitrogen and other substances in the soil more accurately, it is easily affected by soil texture, color, moisture content and surface roughness

A soil nutrient detection device based on visual sense of smell belongs to detection equipment; the three-way guide valve is respectively connected with the gas flow control switch, the micro vacuum pump and the soil sample gas timing collector, the inert gas tank is connected with the gas flow control switch, and the soil sample The gas timing collector is connected with the airtight chamber, and the camera module, the base and the LED light are installed in the airtight chamber, the visual smell sensor array is assembled on the base, the airtight chamber is connected with the exhaust valve, and the embedded image processor passes the wire It is respectively connected with the camera module and the computer pattern recognition system; this device uses the color reaction between the volatile odor of various nutrients in the soil and the visual olfactory sensor to obtain the detection results of the soil nutrient content qualitatively and quantitatively. It has the characteristics of many varieties of soil nutrients, accurate test results, high detection efficiency, low detection cost and strong applicability.
Description
technical field [0001] The invention belongs to detection instruments and equipment, in particular to a soil nutrient detection device based on visual sense of smell. Background technique [0002] The substances in the soil are very complex, among which nitrogen, phosphorus, potassium, organic matter and other nutrients are closely related to the growth of crops. In order to increase crop yield, fertilization is a common method, but there are blind and excessive fertilization in our country, resulting in waste of resources, Environmental pollution and lake eutrophication and other issues. Therefore, accurate and rapid detection of soil nutrient composition and content, and targeted fertilization of soil based on this, are of great significance for improving food production and protecting the ecological environment. [0003] At present, the methods for detecting soil nutrients mainly include chemical analysis, remote sensing measurement and near-infrared spectroscopy. The d...
