Embodiment 1

[0027] like figure 1 For the room-style warehouse shown, the four walls of the warehouse are painted with black and white squares with a side length of 1m, and a column of coded squares on one wall is split into small squares with a side length of 0.5m. In the figure, only the coding method of the bottom surface and two sides is given, and other walls are based on this.

[0028] like figure 2 As shown, the cameras are placed on the four sides of the roof of the room-style warehouse, and the images of the corresponding walls are taken respectively.

[0029] Every certain period, the camera collects the information in the warehouse, and uploads the collected image information to the grain depot monitoring center for analysis and processing. The light irradiated on the warehouse wall is reflected back to the camera, presenting information with different grayscales and sharp contrast in the image. Since the distance between the coding grid and the camera is different, the disp...

Embodiment 2

[0034] like image 3 As shown, the wall of the shallow round warehouse is painted with black and white squares with a side length of 1m, and two rows of squares extending axially at both ends of the same diameter at the bottom of the warehouse are divided into two rows of squares with a side length of 0.5m. The small black and white squares are used as the starting mark, and a vertical scale is installed on the ground beside the projection of the grain inlet at the bottom of the warehouse, and a black and white stripe mark with a width of 0.5m is set on the scale.

[0035] like Figure 4 As shown, the camera is placed on the same generatrix on the top surface of the cone bin, and takes pictures of the bin wall and the scale that are divided into two equal parts by the two starting marks.

[0036] It is known that the radius of the bottom surface of the shallow round silo is R, and the grain storage height is h. When the granary is inverting, the grain is poured in from above ...

Abstract

The invention discloses a grain storage volume detection system, which comprises a granary body, an image acquisition device is arranged on the top of the bin body, and a mark is arranged in the bin body, the image acquisition device collects images in the bin body, and the system distinguishes the images The quantity information identified in the warehouse is converted into the size information of the inner wall of the warehouse, and then the grain volume storage in the grain warehouse is obtained by calculation. The invention adopts the image acquisition and analysis technology, overcomes the complex and huge network structure characteristics of the traditional detection system, and adopts a simple and convenient method for monitoring, which greatly reduces the cost of the monitoring system; it can realize anti-theft monitoring while detecting reserves, and the existing The combination of temperature and humidity detection technology can comprehensively detect the state of grain in the granary, upload the collected data to the monitoring center through the network, and can accurately grasp the situation of grain in all granaries within the monitoring range; it has the characteristics of low cost, high efficiency, and real-time. It is easy to install and the benefits after popularization are more obvious.

Description

technical field [0001] The invention relates to the technical field of electronic detection, in particular to a granary detection system. Background technique [0002] Food is the basic material that human beings depend on for survival, and it is an important material related to the national economy and people's livelihood. According to statistics from the Food and Agriculture Organization of the United Nations, when 925 million people around the world do not have enough to eat, about 1.3 billion tons of food are wasted or lost by humans every year. This scale is equivalent to one-third of the global food production and exceeds the global half of the grain production. Therefore, the food issue deserves full attention. [0003] The storage statistics and safety monitoring of granaries in various places basically adopt traditional and inefficient methods, which cannot adapt to the development of the times. A large amount of grain is stored together. A large amount of strong...
