The invention discloses an online detection device and method for cracks of egg shells, and relates to the field of physical property parameter detection. Comprising a motion control module, an audio signal acquisition module and an audio signal cross analysis module. According to the invention, synchronism of the transmission device and the knocking device is realized by adopting a multi-sensing mode, so that the knocking device has a self-adaptive matching function on the transmission line speed, and the consistency of the detection device on the knocking position is improved; multi-point excitation response signals on the surface of a single egg are collected, comprehensive acoustic information on the surface of the egg is obtained, and the accuracy of egg crack detection is improved; real-time feedback of the rotation angle of the knocking device is adopted, a signal acquisition signal is sent by combining rotation information, and a sampling window is limited in a hardware form, so that the signal-to-noise ratio and the effectiveness of the signal are effectively improved; the cross analysis of response signals of multiple knocks of a single egg is adopted, so that the adaptability of the detection model to the egg individuals is effectively improved, the calculation amount of the egg discrimination model is reduced, and online detection application is facilitated.
Description
technical field [0001] The invention relates to the field of physical parameter detection, in particular to an on-line detection device and method for egg shell cracks based on acoustic response. Background technique [0002] According to relevant research reports, about 10% of fresh poultry eggs have been detected with harmful live bacteria, and about 5% to 8% of poultry eggs have secondary damage. The main reason for this phenomenon is the commercialization of poultry eggs. In the process of mechanical collision and cross-infection, there are a lot of waste of raw materials, resources and food safety hazards. The detection of important indicators related to food safety of eggshell cracks can provide basic guidance data for the mechanization of automatic egg processing, egg hatching and pre-processing of deep processing. [0003] Scholars at home and abroad have reported many reports on the detection of egg shell cracks. From the research results, the use of audio detectio...
