Embodiment Construction
[0009] The implementation of the present invention will be further specifically described below with reference to the accompanying drawings and specific embodiments.
[0010] figure 2 It is a structural schematic diagram of the functional modules of the device of the present invention. The device is composed of a stimulation and sound collection module, a noise filtering module, a chick sex identification module, a screening module, a counting module and a control module. These modules can all be realized in the chick sound collection room. The stress structure and plates of the chick sound collection room are made of metal materials, wood or hard plastic materials, and the lining is made of flexible sound insulation materials; the stimulator uses light stimulation (strong light) flicker several times) or mechanical stimulation (mechanical jitter); the sound acquisition module is composed of a sound sensor, a filter circuit, an amplifier circuit and an A / D conversion circuit...

The invention discloses a recognition device and a method for the gender of a chick, belonging to the field of biotechnology. The technique proposal adopted comprises the following steps of: analyzing the audio frequency of the chick, and finding the differences of audio frequency between the male chick and the female chick and the respective frequency range; and then, constructing a male band pass filter and a female band pass filter depending on the differences of audio frequency the respective frequency range in order to filter the characteristic frequency of the male chick and the female chick respectively; collecting the audio frequency of the chick to be selected and conducting parallel analysis of the collected audio frequency by using the two filters. After the parallel analysis, if the audio frequency remains male, the chick is male chick; if the audio frequency remains female, the chick is female chick. The invention can recognize the gender of the chick easily and quickly, therefore, facilitating to recognize and select the male chick and the female chick automatically with wide application prospect in the chick market.
Description
Technical field: [0001] The invention relates to a method and device for sex identification of chicks, in particular to an electronic sound-based method for sex identification of chicks and a device using the method. Background technique [0002] Since the sex characteristics of the chicks are not obvious, it is basically impossible to distinguish the sex by the sex characteristics of the chicks. Although there are many sex identification methods for chicks at present, mainly through methods such as the anus of the chicks, the movements of the chicks or other physical signs, etc., these methods require personal participation, low work efficiency, and are difficult to apply Automatic sorting technology of male and female chicks. Contents of the invention [0003] Aiming at the above-mentioned defects in the prior art, the present invention provides a method for identifying the gender of a chick, that is, distinguishing the sex of the chick through the sound features (ie, a...
