Problems solved by technology

[0004] 1) New hardware needs to be added to the granary, which is costly and inconvenient to install
[0005] 2) Once there are problems such as power outages and equipment maintenance during use, key information will be lost and grain monitoring will be interrupted
[0006] 3) There is a phenomenon of artificially suspending and destroying the supervision system, making the supervision invalid

Embodiment

[0106] Taking a grain depot in Heilongjiang as an example, the detailed information of the granary is as follows:

[0107] The granary adopts a steel plate structure; its size is 47.5 meters long, 26 meters wide, 6 meters high on the grain surface, and 8 meters high on the warehouse. There are 78 temperature measuring cables, 6 in the north-south direction, n=6, and the distance between the two sides is 5 meters. The wall surface is 0.5 meters; 13 in the east-west direction, m=13, the distance is 3.75 meters, and the two sides are 1.25 meters away from the wall; the temperature measurement points are divided into four layers, k=4, and the height of the first layer of temperature measurement points from the grain surface is 0.3 meters, the temperature measuring point on the fourth floor is 0.5 meters away from the bottom surface, and the distance between layers is about 1.7 meters; the distribution of temperature measuring cables is as follows Figure 3-5 Shown:

Abstract

The invention discloses an ABC strategy method suitable for stored grain digital supervision. The method comprises the steps of 1, determining a sampling range and a temperature measuring point of stored grain storage, and determining a temperature measuring sensor position in the sampling range and a grain temperature tested by a temperature measuring sensor; 2, building a fitting function F(i,j,k,d) of the temperature measuring sensor position and the grain temperature, wherein F(i,j,k,d)=A(i,j,k,d)j2+B(i,j,k,d)j+C(i,j,k,d); 3, calculating a deviation of the fitting function in the spatial position of the temperature measuring sensor and coefficients A(i,j,k,d), B(i,j,k,d) and C(i,j,k,d) of the fitting function when the deviation reaches a minimum value, and calculating a parameter D(i,j,k,d)and a parameter F(i,j,k,d); 4, judging and analyzing the coefficients and the parameters; and 5, summarizing abnormal conditions occurring in the step 4, calculating an abnormal proportion of a certain section in a granary and an abnormal proportion of the whole granary, and performing output.

Description

technical field [0001] The invention relates to the field of granary monitoring, in particular to an ABC strategy method suitable for digital supervision of stored grain. Background technique [0002] From the central to the local level, there is a set of standardized grain circulation management regulations. The inventory information of the grain warehouse is mainly judged through the operation records of entering and leaving the warehouse and manual inspection. This method is time-consuming and labor-intensive. misjudgment. [0003] Recently, methods based on image recognition and video surveillance have emerged, which mainly have the following three defects: [0004] 1) New hardware needs to be added to the granary, which is costly and inconvenient to install [0005] 2) In case of problems such as power outages and equipment maintenance during use, key information will be lost and grain monitoring will be interrupted. [0006] 3) There is a phenomenon of artificially ...
