A method for detecting the state of granary historical inventory quantity based on grain temperature data

Abstract

The invention discloses a grain temperature data-based barn historical stock quantity state detection method. The grain temperature data-based barn historical stock quantity state detection method ischaracterized by comprising the steps of 1, calling barn historical grain temperature data, and completing data cleaning; 2, determining an adjacent-layer temperature difference threshold zone of short position detection to be [-T<me>, T<me>], a variation ratio threshold to be Phi<me>, an adjacent-layer temperature difference threshold zone of semi-warehouse detection to be [-T<mh>, T<mh>], a variation ratio of new grain detection to be Phi<mf> and a standard threshold value of adjacent-layer temperature difference to be Sigma<mf>; 3, acquiring adjacent-layer temperature difference Delta T<h,u-d> of adjacent cross sections from an upper layer to a lower layer during the historical storage process of a to-be-detected barn and variation ratio Phi<He, u-d> of short position, judging whethereach layer of cross section conforms to Delta T<h, u-d><=[-T<me>, T<me] and Phi<He, u-d>>=Phi<me> or not from top to bottom, and considering that the to-be-detected barn is in a short position state if formulas are simultaneously satisfied. By analyzing adjacent-layer temperature difference, the variation ratio and standard difference of the adjacent layer temperature difference of historical grain temperature, a set judgment threshold is combined, and detection of barn stock historical quantity state change during the storage process is achieved.

Description

technical field [0001] The present invention relates to the technical field of granary storage, and more specifically, the present invention relates to a method for detecting the historical stock quantity status of granaries based on grain temperature data. Background technique [0002] There is a large amount of grain in stock, and the storage period is long (generally 2-4 years). During this long-term storage period, it is easy to have problems with the authenticity of the quantity of grain in stock, such as trade-in for goods, violation of regulations, etc., and inventory inspection will be carried out every year. Inventory authenticity is one of the important parts of inventory inspection, and historical inventory quantity inspection is an important method to judge the authenticity of inventory. However, when conducting inventory inspections every year, the inspectors can only check the historical inventory quantity based on vouchers, documents and other information, and...

AI Technical Summary

Problems solved by technology

[0006] 1. Most of the existing granary historical inventory detection methods are completed by manually reviewing the records, and the manual records are highly subjective, which cannot guarantee the objectivity of checking the actual inventory status change detection of the granary

[0007] 2. The manual inspection of historical inventory quantity is heavy workload, low work efficiency, and difficult to find problems

[0008] 3. The state detection method of the existing granary historical storage process does not have a clear type of detection result, the type of inventory state to which the detection result belongs is not clear, the parameters used in the detection process are relatively simple, and the accuracy of the detection result is not high
