Multifunctional rapid soil nutrient detection device based on halogen lamp combined light source

Abstract

The invention discloses a multifunctional rapid soil nutrient detection device based on a halogen lamp combined light source. The multifunctional rapid soil nutrient detection device is composed of three parts, namely a detection module, a microprocessor and a GPS (Global Position System) module, and relates to a power supply module, a voltage stabilization module, a sample module, a detection module, a display module, the GPS module, an internet access module, a processor module, a light source combination manner and a structural design. According to the soil nutrient detection device, the microprocessor adopts an embedded single-board computer which has a fast speed, a large internal storage, abundant interfaces and simple power supply. The detection module is powered from the microprocessor by adopting a USB (Universal Serial Bus) data line. The device is compact in structure, convenient to move and carry and good in stability; meanwhile, indexes of a plurality of soil nutrients (including nitrogen, phosphorus, potassium and organic matters) can be analyzed simultaneously, and the device also has a GPS function so as to conveniently read out global longitude and latitude coordinates to realize real-time positioning.

Description

technical field [0001] The invention relates to a soil nutrient detection device, in particular to a multifunctional soil nutrient rapid detection device based on a halogen lamp combined light source. Background technique [0002] Soil nutrients are the nutrient elements provided by the soil for plant growth, and it is an important indicator of soil fertility. Knowing the nutrient information of soil in real time is one of the basic parts of digital agriculture, and it is of great significance to guide agricultural scientific production. Among them, soil nutrient information mainly refers to soil nitrogen content, potassium content, phosphorus content, organic matter content, electrical conductivity, humidity and so on. [0003] The advantages of near-infrared spectroscopy, such as simplicity, rapidity, low cost, and simultaneous determination of multiple components, have attracted people's attention. The design of the light source in the test has a great influence on the ...
