Detection and reorganization of hatching living bird embryo

Abstract

The invention relates to detection and reorganization of a hatching living bird embryo. At present, testing methods of the hatching living bird embryo comprise apexcardiogram (ACG), ballistocardiogram (BCG), electrocardiograph (ECG) and impedance cardiogram (ICG). Because the methods have a variety of defects, a testing system of a weak acoustic signal of the living bird embryo is designed by using the weak acoustic signal sent by the hatching living bird embryo and combining the acoustic theory with the characteristics of a rotational ellipsoid, therefore, the invention solves the problem of recognizing the mode of the living bird embryo. Tests on the weak acoustic signal of the living chick embryo show that: the detection system has the advantages of novel design, simple operation, strong practicability, low cost and remarkable effect, and can not cause any adverse effects on the living chick embryonic development. The invention is also suitable for the mode reorganization and the weak acoustic signal detection of other living bird embryos.

Description

technical field [0001] The identification system for the weak sound signal of live bird embryos in hatching is a novel, practical and reliable weak sound signal detection device designed on the basis of mechanical structure. The invention combines the acoustic theory with the properties of the ellipse to develop a unique system capable of detecting weak acoustic signals of live bird embryos in hatching, and uses the system for pattern recognition of 10-day live chicken embryos. The invention belongs to the field of weak sound signal detection and recognition. Background technique [0002] At present, the testing methods for the development status of living bird embryos in hatching include: acoustic electrocardiogram (ACG), cardiac pulse recording graph (BCG), electrical signal recording graph (ECG) and impedance electrocardiogram (ICG). These four methods have their own advantages and disadvantages: Among them, the tests of electrical signal recording graph (ECG) and impeda...

AI Technical Summary

Problems solved by technology

These four methods have their own advantages and disadvantages: Among them, the tests of electrical signal recording graph (ECG) and impedance electrocardiogram (ICG) need to make several small holes on the live eggshell during the incubation period, and three electrodes are respectively inserted into different small holes. And maintain a certain depth, by measuring the electrical signals of the three electrodes on the living embryo to identify the development of the chicken embryo in the hatching period. The signal energy obtained by these two methods is relatively large, and the measurement is relatively easy, but the eggshell needs to be destroyed. The development of embryos should be stopped after detection; the acoustic electrocardiogram (ACG) and cardiac pulsation record (BCG) are used to judge the growth and development of chicken embryos in the hatching period by measuring vibration and acoustic signals, without destroying egg shells, and will not harm live chickens. Embryo development has adverse effects, but the signal is too weak, and the background noise is much stronger than the measured vibration and acoustic signals (signal-to-noise ratio is too small), it is difficult to measure the ideal result
