A portable poultry egg quality detection method

Abstract

The invention discloses a portable poultry egg quality detection device and method. According to the device, a poultry egg support frame is fixedly arranged on the bottom surface in a box; a chute is formed in the poultry egg support frame, and a black case and a motor supporting plate are respectively fixed on the poultry egg support frame; a rack which can slide on the chute is connected with the chute; the rack is fixedly connected with one end of a driving lever; the other end of the driving lever stretches out of the box through a slot; a camera is arranged on the top of the rack; a sound pick-up is arranged inside a knocking rod; two sticks which are horizontally parallel to each other and have the equal heights are arranged on the top of the black case; the knocking rod is positioned just above the poultry eggs and is used for knocking the poultry eggs with different areas; the sound pick-up picks up an acoustic wave signal and transmits the signal to a tablet personal computer for judging whether a crack exists on each poultry egg; the driving lever is manually driven outside the box, so that the rack slides to the chute until the camera is positioned just above the poultry egg, and the egg shape index, the weight, the internal quality and other quality indexes of the poultry egg are obtained. By the adoption of the two-station design, the comprehensive quality indexes can be rapidly and accurately obtained, and the dynamic and online real-time detection on the poultry egg is realized.

Description

technical field [0001] The invention is based on acoustic detection and image detection technologies, belongs to the technical field of food quality detection, and relates to a portable device capable of detecting poultry egg quality as a portable egg detection instrument. Background technique [0002] The nutritional value, freshness, damage, blood mole, meat spot and other defects of poultry eggs are the detection indicators of poultry egg quality. In recent years, poultry egg quality testing presents a lot of testing on the appearance or internal quality information of poultry eggs, but most of them are single-indicator testing, lack of comprehensive quality testing devices, and cannot fully meet the requirements of poultry egg quality testing. For example: Chinese patent publication number is CN85204472, title is " poultry egg detector ", has introduced a kind of portable poultry egg quality detection device, but it only detects this single index of the freshness of poul...

Problems solved by technology

In recent years, poultry egg quality testing presents a lot of testing on the appearance or internal quality information of poultry eggs, but most of them are single-index testing, lack of comprehensive quality testing devices, and cannot fully meet the requirements of poultry egg quality testing

For example: Chinese patent publication number is CN85204472, title is " poultry egg detector ", has introduced a kind of portable poultry egg quality detection device, but it only detects this single index of the freshness of poultry egg; Chinese patent publication No. It is CN101413928A, titled "Fast online non-destructive detection device and method for cracks in poultry eggs based on acoustic characteristics", which introduces the method and device for non-destructive detection of cracks in poultry eggs, but only detects cracks in poultry eggs; Chinese patent publication number is CN101455183A, titled "Detection method of poultry egg size and egg shape index" introduces a way to detect poultry egg weight and egg shape index by taking reflection images of poultry eggs, but the weight of poultry eggs is not only related to volume but also related to the freshness of poultry eggs. Therefore, the detection method has a large error

Although the above-mentioned published patent documents provide means for poultry and egg quality detection, the existing problem is that some devices have relatively large structures, are inconvenient to carry, and can only be used in laboratories, and the scientific nature of the method needs to be improved. to test
