Embodiment 1

[0084] Embodiment 1, poultry egg detection device based on visible / near-infrared spectrum

[0085] 1. Device structure

[0086] Such as figure 1 As shown, the poultry egg detection device based on visible / near-infrared spectrum in the present embodiment is made up of detection dark box 9, and following device:

[0087] The light source 8 is set inside the detection dark box 9 and is a halogen lamp, specifically two 12V20W Philips tungsten-halogen lamp beads (G4 lamp beads), with a light-emitting band of 200-2500nm; the power of the light source needs to be determined according to the sample, and the power of the light source It is the most basic condition to determine the intensity of the light transmitted through the sample. The greater the power, the greater the intensity of the transmitted light. For varieties with larger volume (or too large long axis and short axis), it is necessary to use a more powerful light source. The specific operation can be: within a short inte...

Abstract

The invention relates to a visible / near infrared spectroscopy-based poultry infertile egg detecting method and device. The device is a poultry egg detecting device based on visible / near infrared spectroscopy. The device comprises a power source (1), a heat sink (2), an object carrying table (3), a light probe (4), a support (5), an optical fiber (6), a temperature sensor (7), a light source (8) and a detection dark box (9) and also comprises an optical signal sensor (10). The device can monitor environment temperatures in a poultry egg detection process and prevents influences of overhigh temperatures on normal incubation of poultry eggs to be detected. The adjustable probe is adopted, and the position of the light probe can be fixed without adjustment when samples of a same kind are detected, thus reducing detection time. The device adopts a non-contact detection process, overcomes disadvantages that traditional egg candling or other detecting methods need contact with poultry eggs to be detected, and avoids the problem of outside contamination caused by contact type detecting methods. The device and the method (through building an optimum mathematic model from poultry egg spectrum data and fertilization results) can detect, in high accuracy, infertile eggs and fertile eggs before incubation and can increase the production efficiency.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a method and device for detecting non-sperm eggs of poultry, especially a method and device for detecting non-sperm eggs of poultry based on visible / near-infrared spectrum. Background technique [0002] During the hatching process of poultry eggs, some eggs cannot be hatched in the end, resulting in a lot of waste. According to the 2006 statistics from the National Agricultural Statistics Service of the United States Department of Agriculture (USDA, NASS), the embryonic development rate of chicken eggs is only 86% to 99%, a large part of which is caused by unfertilized eggs. For enterprises capable of incubating, if unfertilized eggs are found as early as possible, on the one hand, more resources can be saved, waste can be reduced, and the production efficiency of the enterprise can be improved; on the other hand, bacterial infection caused by undeveloped eggs can be avoided breedin...
