[0003] Corrugated paper is cheap, easy to degrade, and has superior performance. It is the first choice for modern express packaging. When producing corrugated paper, due to production process or machine errors, the thickness of the corrugated paper may be larger than the customer’s standard size. Increased cost is voluntary waste for the society; under the same standard, the weight of corrugated paper with a thickness exceeding the standard is often greater than the weight of standard products, which will easily lead to an increase in postal costs and unnecessary voluntary waste
[0004] The existing technology is slow in testing the thickness of corrugated paper, and most of the existing technologies use contact testing to easily lead to inaccurate testing.

Embodiment 1
[0099] Embodiment 1, the production control system of corrugated paper comprises a hardware system, and the hardware system comprises a detection platform (PT1), a foreground board (B1), a background board (B2), a camera, an image acquisition card, and a computer;
[0100]The detection platform (PT1) has a sample plane, and the sample plane is used to place corrugated paper samples (ZZ);
[0101] The sample plane of the detection platform (PT1) is located on the space path of the foreground plate (B1) and the background plate (B2);
[0102] The distance from the foreground board (B1) to the camera is greater than the distance from the background board (B2 to the camera;
[0103] The top edge of the foreground board (B1) is a horizontal line, and the distance from the top horizontal line of the foreground board (B1) to the sample plane of the testing platform (PT1) is equal to the customer's standard thickness of corrugated paper;
[0104] The top edge of the background plate ...
Embodiment 2
[0192] Embodiment 2. On the basis of Embodiment 1, the top of the background board (B2) is adjustable so as to adapt to different customer standards.
Embodiment 3
[0193] Embodiment 3. On the basis of Embodiment 1, in the implementation of the 'image judgment operation flow', the pictures captured by the camera are first preprocessed, so that the judgment is more stable, the error rate is reduced, and the system stability is increased.
[0194] It is worth noting that, in order to cater to human reading habits and facilitate understanding, both the first statistical branch process and the second statistical branch process use the first variable and the second variable as data expression symbols, but this will not lead to misunderstanding.

Abstract
A method for detecting the quality of corrugated paper through a computer is used for detecting whether the thickness of the corrugated paper is larger than the preset standard thickness or not. If the thickness of the corrugated paper is greater than the preset standard thickness, it is determined that the corrugated paper is an inferior-quality product; if the thickness of the corrugated paper is not greater than the preset standard thickness, it is determined that the corrugated paper is a good product of the section; and the color value of the foreground color (S-B1) is different from thecolor value of the background color (S-B2). The corrugated paper production control system adopts the method for detecting the quality of the corrugated paper by utilizing the computer to detect whether the thickness of the corrugated paper is too thick or not. The invention provides a new thought for detecting the quality of corrugated paper. The method and the system are quick, accurate and lowin cost.
Description
technical field [0001] The invention relates to the field of corrugated paper production, in particular to a method for detecting the quality of corrugated paper by computer and a corrugated paper production control system. Background technique [0002] Corrugated paper is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper interlayer (commonly known as "pit sheet", "corrugated paper", "corrugated core paper", "corrugated core", "corrugated base paper") and a layer of cardboard (Also known as "boxboard", "boxboard"). It has high mechanical strength and can withstand bumps and falls during handling. The actual performance of a corrugated box depends on three factors: the properties of the medium and paperboard and the construction of the box itself. [0003] Corrugated paper is cheap, easy to degrade, and has superior performance. It is the first choice for modern express packaging. When producing corrugated paper, due to production pr...
