Example Embodiment

[0025] Reference Figure 1 to Figure 5 , A method for batch automatic collection of soil spectra, the method includes the following steps:

[0026] (1) Power-on reset: After the electrical components are powered on, run the computer program to control the rotation of the sample rotating disk 1 so that the circular hole labeled "S" is moved under the optical probe 10, and the optical standard plate 6 is placed on the "S" circle And make the light emitted by the optical probe 10 converge in the middle of the optical standard plate 6. Run the computer program to obtain the emission spectrum of the optical standard plate;

[0027] (2) Place the sample cup: put the soil sample to be tested into the sample cup 5, and put the sample cup 5 into the round hole 7 of the sample rotating disk 1 in turn;

[0028] (3) Collect soil sample spectrum: Run the computer program, send step rotation command to stepper motor controller 17, rotate the sample rotating disk 1 by a round hole angular distanc...

Abstract

The invention discloses an automatic mass collection method for a soil spectrum and a special collection apparatus. The collection apparatus comprises a support platform, a sample rotation disk, a sample cup, a plane bearing, a stepping motor and an optical probe, wherein the plane bearing is arranged on the middle portion of the upper end of the support platform, the sample rotation disk is arranged on the plane bearing, and is provided with a plurality of round holes along the edge of the circumference, the sample cup can be placed inside the round hole arranged on the sample rotation disk, the stepping motor is arranged inside the support platform, the stepping motor and the sample rotation disk form shaft coupling through a center hole arranged on the center of the sample rotation disk, and the optical probe is arranged just above the round hole arranged on the sample rotation disk. According to the present invention, design of the whole apparatus is simple, manufacturing cost is low, an automation degree of the soil spectrum collection is high, and the apparatus is suitable for spectrum collection and analysis of indoor mass soil samples.

Description

technical field [0001] The invention relates to a batch automatic collection method of soil spectrum and a special collection device thereof, belonging to the field of agricultural information detection equipment. Background technique [0002] Modern agriculture requires that a corresponding fertilization plan be formulated according to the actual fertility of the farmland and the demand of the crops. Traditional soil nutrient physical and chemical testing techniques cannot meet the real-time testing requirements of a large number of soil samples. Objectively, it is necessary to develop technologies and testing equipment that can quickly test soil nutrient content on a large scale. In recent years, near-infrared spectroscopy has been gradually used in indoor or outdoor testing of soil nutrients due to its advantages of simple testing, no need for sample pretreatment, and no chemical pollution. At present, the collection of soil spectra must rely on manual detection of soil ...
