Embodiment Construction

[0024] The core of the national grain storage quantity detection system is how to obtain the quantity of grain stored in each granary in the grain depot conveniently, quickly and accurately, and effectively detect the change of the quantity of stored grain. Due to the characteristics of low price and large quantity of grain, the detection equipment for the quantity of stored grain is required to be low in cost, cheap in price, fast in detection speed and high in accuracy. Based on these requirements, the pressure sensor-based detection method for the quantity of grain stored in grain storage proposed by the present invention provides technical means for accurately grasping the quantity of national grain reserves in my country in real time, and serves the management and scientific decision-making of grain management departments.

[0025] At present, the commonly used granaries include flat warehouses, shallow round warehouses, deep round warehouses, etc., with different shapes ...

Abstract

The invention relates to a method for detecting the quantity of stored grains in a granary based on a pressure sensor, belonging to the technical field of detection. The detection method in the invention can calculate pressure values of the bottom surface and the side surfaces of the granary by adopting the output values of the pressure sensor according to the arrangement modes of pressure sensors of different types, and calculates the quantity of the stored grains in the granary based on an established model. The detection method in the invention has high measurement precision, strong practicability and low detection cost, can meet the actual requirements on detecting the quantity and distribution of the stored grains in nationwide granaries on line in real time, provides a technical means for accurately mastering the quantity of the stored grains in China in real time and gives services to guaranteeing the grain safety of China.

Description

Technical field [0001] The present invention involves a detection method for the number of grain storage and distribution. Especially a stress -based grain -based grain storage grain detection method using pressure sensors to detect the number of grain storage quantities in real -time detection of grain storage quantity is the field of detection technology. Background technique [0002] Food is one of the three major strategic resources of the country and is related to the national economy and people's livelihood.Increasing consumption level and increasingly important quality and safety issues.Maintaining a certain number of varieties and quality grain reserves is an indispensable measure to ensure the safety of national food safety, ensure the safety of food quality and the safety of food. [0003] The online monitoring of the number of grain storage foods is a key means to ensure the safety of the number of grains, in order to ensure the accuracy and authenticity of the country...
