Embodiment 1

[0039] The duck egg quality non-destructive testing and grading equipment trial-produced by the present invention is as attached figure 1 The overall schematic diagram. On the automatic production line, the duck eggs are placed on the egg trays of the conveyor belt at a distance of 30cm, and the conveyor belt advances at a speed of not less than 30cm / s. The inspected egg first arrives at the damage detection position, and the program-controlled detection device for identifying damaged eggs collects the sound signal of egg knocking and analyzes and judges it, and then controls the egg damage sorting mechanism based on the judgment result. Therefore, the egg damage measurement and control software has the following functions: synchronously collect sound signals; analyze and process the collected sound data in real time to distinguish between shell eggs and damaged shell eggs; output control signals to the egg damage sorting mechanism according to the judgment results; provide wo...

Embodiment 2

[0047] The egg image detection device is composed of a light chamber, a color camera, an image acquisition card, an industrial control computer, a digital input and output card, a PLC driving mechanism, and a grading mechanism. Such as Figure 8 shown.

[0048] Image acquisition card: Convert the video signal from the CCD into a digital signal recognizable by the computer, and send it directly to the internal video memory of the computer through the PCI bus of the computer and the DMA controller to complete the computer's acquisition process of the external image. Its technical features and indicators are as follows: color and black and white image acquisition; video input is standard PAL, NTSC or SECAM signal; six-way composite video input selection or three-way Y / C input selection; brightness, contrast, chroma, saturation software Adjustable; the maximum resolution of the image acquisition display is 768×576; it has the function of opening the window, the window can be squa...

Embodiment 3

[0061] In order to improve production efficiency, the image processing module needs to detect all egg quality parameters (including shell thickness, egg core color, size, and freshness) at one time when the egg freshness meets the conditions. For this reason, a parameter index is used to represent the final comprehensive coefficient of egg quality. Different indexes correspond to different classification situations.

[0062] Let dthick be the measure of shell thickness, and nthick the grade of eggs classified by shell thickness. If eggs are divided into 2 grades according to shell thickness, and the intermediate threshold value is valthick, then:

[0063]

[0064] Let dcolor represent the measurement of egg core color, and ncolor represent the class of eggs sorted by egg core color. If the eggs are divided into 3 grades according to the color of the egg core, and the intermediate thresholds are set to valcolor1 and valcolor2, then:

[0065]

[0066] Use dsize to repre...

Abstract

The invention relates to a fowl eggs quality non-destroying automatic detection apparatus and method therefore, wherein the apparatus includes an operation system which comprises supervisory instrument of breakage eggs discrimination for programmed computer system control, picture pattern acquisition and information supervisory instrument for eggs quality identification, and a grading machine assembly for rejecting breakage eggs and accomplishing fractionation.

Description

technical field [0001] The invention belongs to poultry egg grading and processing machinery, in particular to non-destructive automatic detection and grading equipment and methods for poultry egg quality. Background technique [0002] In poultry egg processing, it is required to detect poultry egg shell damage, egg size, egg freshness, egg core color and egg shell thickness. According to the test and grading results, they are processed into different grades of preserved eggs, red and yellow salted eggs, red heart best salted eggs or used for other purposes. The detection and grading of poultry eggs that has been passed down to the present adopts the artificial egg method of manual workshops. The egg canister uses an incandescent light source, manually aligns the egg at the light leakage of the opening of the canister, and the operator can visually identify the color grade and freshness of the egg core according to the image color of the egg ...
