Problems solved by technology

[0004] At present, my country mainly conducts supervision and inspection of grain storage work through manual census. This method is prone to loopholes in actual work, and the phenomenon of deception and falsification is unavoidable, and the reliability of the census results cannot be fully guaranteed.
[0005] In order to ensure the safety of the quantity and quality of the national grain storage, the state has to deploy personnel from the State Grain Administration, China Agricultural Development Bank, C

Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0037] As shown in Figures 1 to 3, a method for measuring the quantity of grain stored in a grain depot uses a camera 1, a laser sensor 2, a pressure sensor 3 and a PC 4 to form a measurement system. The specific measurement method is as follows:

[0038] a, measure the volume of the grain pile 6 with the laser sensor 2, namely the height from the ground of the granary to the grain surface 5, and the length and width of the grain pile 6 (for the square bin) or the diameter of the grain pile (for the round bin) ), the volume V of the square is obtained by the length * width * height, and the volume V of the circular warehouse is obtained by the circumference ratio * radius * radius * height, and starts the camera 1 to take real-time photos simultaneously, and stores them in the database of the PC 4;

[0039] b. Correct the volume measured by th...

Abstract

This invention relates to one food storage volume measurement method, which comprises the following steps: using laser sensor to measure its volume and starting cameral head for shot stored into PC database; correcting according to the volume by laser sensor; measuring food storage intensity by use of pressure sensor to weight sensor above column weight and measuring sensor food column height through laser sensor; computing food column intensity according to the weight, height and pressure area; computing food storage total weight according to the intensity and volume.

Description

technical field [0001] The invention relates to the field of monitoring systems for grain storage in grain depots, in particular to a method for measuring the quantity of grain stored in grain depots. Background technique [0002] At present, with the increase of our country's population and the acceleration of industrialization, the per capita arable land area continues to decline. How to ensure the food problem of the 1.3 billion people in the country and how to ensure the country's food security? It is very important to maintain a certain amount of food reserves. Grain depots The security of stored grain is increasingly showing its importance. [0003] Since the 1990s, the Chinese government has successively used tens of billions of national debt funds to build a national grain reserve with a capacity of 110 billion catties for national grain reserves. However, how to truly realize the "two transformations" in storage management, that is, to ensure the authenticity of th...
