Method for accurately and reversely solving target point of heating grain by using existing temperature measurement network

Abstract

The invention provides a method for accurately and reversely solving a heating grain target point location by using an existing temperature measurement network in combination with the existing real-time dynamic grain temperature monitoring network of bungalow grain warehouses and by using the temperature measurement point data and the change thereof obtained by the temperature measurement network aiming at the bungalow warehouse types adopted by most grain storage in China. The method specifically comprises the following steps: S1, setting a temperature measurement network in the horizontal warehouse; s2, determining a heating point neighborhood in the horizontal warehouse; and S3, in combination with the temperature measurement network, according to the neighborhood of the heating point, calculating and obtaining a target point location of the heating grain. According to the method, the position of the starting hot point can be accurately calculated, so that the heating area can be ventilated or turned over, rapid cooling is realized, and the grain storage safety is ensured.

Description

【Technical field】 [0001] The invention belongs to the technical field of grain storage, and specifically relates to a method for accurately reversing the target point of calorific grain by using an existing temperature measurement network. 【Background technique】 [0002] The vast majority of my country's grain storage is in one-story warehouses or tall one-story warehouses. During the grain storage process, measures such as moisture control in grain storage, disinfecting of grain insects, and ventilation and cooling in grain storage rooms are required to achieve a systematic grain storage environment and maintain a stable environment. Maintain as much as possible. However, grain seeds are organisms, even in a systematic grain environment, there will be increased moisture and insect pests caused by grain biological activities (grain respiration, etc.), and the macroscopic performance will always exist in the stored grain. These hot spots will cause the temperature of the loca...

However, grain seeds are organisms, even in a systematic grain environment, there will be increased moisture and insect pests caused by grain biological activities (grain respiration, etc.), and the macroscopic performance will always exist in the stored grain. Distributed hot spots, these hot spots will lead to an increase in the temperature of the local grain pile, which will lead to the deterioration of the stored grain quality, resulting in the loss of stored grain
