Description

Technical Field

[0001] The present invention relates to the technical field of environmental detection, and particularly to a rapid multi-parameter soil conventional index detection instrument and an implementation method thereof. Background Art

[0002] With the development of modern agriculture and the enhancement of environmental protection awareness, the requirements for soil quality are increasing day by day. Traditional soil detection methods usually rely on laboratory analysis, which is not only time-consuming and costly, but also requires professional technicians to operate complex equipment, making it difficult to meet the need for quickly and accurately obtaining soil information. Existing soil detection means often focus on the measurement of a single index, such as pH value or conductivity, lacking the ability to perform multi-parameter detection simultaneously, which limits the comprehensive understanding of the overall soil condition. In addition, the sample pretreatment process is complex and has a lot of manual intervention, which is likely to lead to uneven samples or insufficient representativeness, thus affecting the accuracy of the detection results. Traditional detection methods also lack effective data processing and transmission mechanisms, resulting in low data analysis efficiency, being difficult to provide real-time feedback to users, and unable to guide agricultural production and environmental governance work in a timely manner. Therefore, there is an urgent need for an instrument with a compact design, high degree of automation, capable of quickly and accurately detecting a variety of soil conventional indexes and having data processing and transmission functions, to overcome the defects in the prior art and provide a more efficient, accurate and comprehensive soil quality assessment scheme.

[0046] The working principle of the present invention is as follows: The design of this multi-parameter rapid detection instrument for conventional soil indicators aims to provide an efficient and accurate solution for quickly evaluating soil quality on-site. The instrument includes key components such as a sample processing cylinder 1, a sensor module 3, a data processing unit 4, and a display screen 5.

[0047] First, put the collected soil samples into the sample processing cylinder 1. Inside the sample processing cylinder 1, there is a processing chamber 9, in which a crushing component and a mixing component are installed in sequence from top to bottom. The crushing component is driven by a crushing motor 13, and the soil is crushed by multiple crushing blades 15 on the rotating roller 14 to ensure that the soil particles reach a suitable particle size for detection. Subsequently, the mixing rod 8 located at the lower half of the rotating roller 14 further mixes the soil samples to ensure the uniformity and representativeness of the samples and reduce the errors caused by manual intervention.

[0048] The pre-treated soil samples flow into the corresponding detection grooves 12 on the detection table 6 through the discharge pipe 10 provided at the lower end of the sample processing cylinder 1.

Specifically, the pH value sensor is used to accurately measure the hydrogen ion concentration in the soil solution; the conductivity sensor measures the conductivity of the soil solution by the induction method to reflect the content of soluble salts in the soil; the humidity sensor measures the soil water content by the capacitive method.

In addition, based on the regression line model algorithm, the data processing unit 4 can also predict the soil organic matter content according to the measured soil humidity and pH value. The specific model formula is Finally, the calculated values of various soil conventional indicators are presented to the user through the display screen 5, and the display methods include digital display and chart display, and at the same time, it supports the function of historical data analysis and comparison. In addition, the display screen 5 is also equipped with a wired output terminal and a wireless transmission module, which can conveniently transmit the data to other external devices or systems for further data analysis and long-term monitoring.

[0050] In summary, the present invention realizes a one-stop solution from sample preparation to result output by integrating automated sample pre-treatment, multiple sensor integration, and advanced data processing technologies, greatly improving the work efficiency and accuracy of soil quality detection.

[0051] The following is an example of predicting soil organic matter:

[0052] The calculation formula is:

[0053] y = β0 + β1x1 + β2x2 + ∈

[0054] Where y is the organic matter content, x1 is the pH value, x2 is the humidity, β1 and β2 are the parameters to be estimated, and ∈ is the error term;

[0055] The following parameters were determined through experiments: β0 = 5.0, β1 = -0.3 (the influence coefficient of pH value on the organic matter content), β2 = 0.08 (the influence coefficient of humidity on the organic matter content);

[0056] A set of actual measurement data was obtained from the sensor module: Soil pH value (x1): 6.5; Soil humidity (x2): 30% (expressed as 0.3 as the input).

[0057] Substitute the known parameters and measurement data: Substitute the above parameters and measured values into the regression line model formula, and we get:

[0058] y = 5.2 - 0.3×6.5 + 0.08×0.3

[0059] Calculate the prediction result:

[0060] y = 5.2 - 1.95 + 0.024 = 3.274

[0061] This means that, given a soil pH value of 6.5 and a humidity of 30%, the predicted soil organic matter content is approximately 3.274%.

[0062] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural manners to this technical solution without creative efforts to cover the embodiments, they shall fall within the protection scope of the present invention.
