In the process of weighting, since the units of the specific grain parameters are different, only the numerical value needs to be considered in the weighting, and the units are normalized.
In addition, the mode of determining the matching value between the current grain condition parameter and the sampling detection parameter can also determine the sub-matching degree corresponding to each sub-parameter difference according to each sub-parameter difference, calculate to obtain the average matching degree between each sub-matching degree, take the average matching degree as the matching value, for example, the sub-parameter difference obtained by comparing the current grain temperature with the sample grain temperature is 0.3 ℃, and the sub-matching degree can be determined to be 100% according to the preset temperature tolerance range +/-0.5 ℃; for another example, the difference value of the sub-parameters obtained by comparing the current grain humidity with the sample grain humidity is 5%, and the sub-matching degree can be determined to be 67% according to the preset temperature tolerance range +/-3% RH; for another example, the difference between the sub-parameters obtained by comparing the moisture content of the front grain with the moisture content of the sample grain is 0.8%, and the sub-matching degree can be determined to be 60% according to the preset tolerance range of the moisture content of + -0.5%, so that the average matching degree can be determined to be 76%, namely the matching value is 76%.
And finally, directly taking the matching value as the detection accurate value of the grain storage ecological regulation device.
In an embodiment, the detection accuracy value can also be calculated by acquiring the grain type in the grain storage ecological regulation device, determining the corresponding correction coefficient according to the grain type, and calculating the product of the correction coefficient and the matching value. The grain species can be different species, such as corn and wheat, or different varieties, such as rice.
The mode of determining the detection accurate value according to the grain type considers that different attributes, particularly different respiration, of each grain are displayed during storage, and the detection accurate value of the stored grain ecological regulation device can be accurately analyzed and judged to a greater extent, so that the detection accurate value of the stored grain ecological regulation device is more scientific.
