Description

Technical Field

[0001] This disclosure relates to the field of intelligent agricultural technology, and in particular to an egg sex detection device and method. Background Technology

[0002] In the field of egg sex determination, optical detection methods have become a focus of current research due to their advantages such as non-destructiveness, lack of pollution, and high-speed detection.

[0003] As the embryo develops, the internal structure of the egg becomes increasingly complex, and the eggshell thickness and light absorption characteristics change significantly. This leads to a substantial decrease in the intensity of transmitted light in the later stages, making optical signals easily attenuated or even unable to penetrate, thus limiting detection during the mid-to-late incubation stages. There is an urgent need for a data acquisition device capable of stably acquiring internal optical information of the egg at any stage of incubation, and to achieve accurate detection of the egg's sex through innovative optical path structures. Summary of the Invention

[0004] In view of this, the purpose of this disclosure is to provide an egg sex detection device and method, which can specifically solve existing problems.

[0005] Based on the above objectives, in a first aspect, this disclosure proposes an egg sex detection device, comprising: a base, wherein an egg tray is disposed at the center of the upper surface of the base, the egg tray being used to hold the egg to be detected upright, the upper surface of the base being a reflective surface, and the egg tray being connected to the reflective surface and recessed downwards; a light source area, the light source area being located above the base, at least two light sources being disposed within the sidewall of the light source area, the light sources being located below the horizontal plane where the egg equator is located; and a light-focusing area, disposed above the light source area, a light-blocking part being disposed between the light-focusing area and the light source area, the center of the light-blocking part being provided with a circular light-collecting opening, and the light-focusing area being used to collect light from below the light-collecting opening.

[0006] Secondly, a method for detecting the sex of an egg is also provided, employing any of the devices described in the first aspect. The method includes: placing the egg to be tested upright on the egg tray of the base, and placing the light-focusing area above the egg to be tested so that the upper part of the egg to be tested passes through the light-collecting opening; illuminating each light source in the light source area so that each light source illuminates the egg to be tested in a direction offset upward in the horizontal direction; and collecting light from below the light-collecting opening through the light-focusing area.

[0007] Thirdly, an electronic device is also provided, including a memory, a processor, and a computer program stored in the memory and executable on the processor, the processor running the computer program to implement the method of the second aspect.

[0008] Fourthly, a computer-readable storage medium is also provided, on which a computer program is stored, said computer program being executed by a processor to implement the method described in any of the second aspects.

[0009] Fifthly, a computer program product is also provided, comprising a computer program that is executed by a processor to implement the method described in any of the second aspects.

[0010] In summary, this disclosure offers at least the following beneficial effects: it allows a portion of the light emitted from the light source to penetrate the egg and be collected by the focusing area, while another portion is reflected from the bottom and re-transmitted, resulting in one or even multiple reflections within the egg. This enhances the signal intensity, forming an enhanced composite optical path and effectively improving the problem of decreased light transmittance during the later stages of incubation. The use of a light-blocking design blocks direct light interference, ensuring the purity of the collected light from the transmission path and improving the signal-to-noise ratio.

Detailed Implementation

[0013] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0014] It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other. This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] Figure 1 This invention discloses an egg sex detection device. In an embodiment of this invention, the device includes: a base 1, with an egg tray 12 disposed at the center of its upper surface for holding the egg to be tested upright; the upper surface of the base 1 is a reflective surface 11, and the egg tray 12 is connected to the reflective surface 11 and recessed downwards; a light source region 2, located above the base 1, with at least two light sources 21 disposed within the sidewall of the light source region 2, the light sources 21 being located below the horizontal plane containing the egg's equator; and a focusing region 3, disposed above the light source region 2, with a light-blocking portion 31 disposed between the focusing region 3 and the light source region 2, the center of the light-blocking portion 31 having a circular light-collecting opening 32, the focusing region 3 collecting light from below the light-collecting opening 32.

[0016] When the egg is placed upright with the air cell facing upwards (larger end facing upwards), the egg tray 12 is used to place the egg below the equator (i.e., the pointed end). The egg equator refers to the circumference perpendicular to the long axis of the egg that divides the egg into upper and lower halves (when the egg is upright).

[0017] The light source area 2 can provide a light source 21. The light source area 2 and the focusing area 3 can be connected or in contact.

[0018] The number of light sources 21 is usually even, and they can be arranged axially symmetrically about the major axis of the egg or centrally symmetrically. For example, the light sources 21 can be LED light sources 21, such as LED arrays, halogen lamp light sources 21, or laser frequency-scanning light sources 21. The light sources 21 can have automatic dimming functions.

[0019] A light-receiving port 32 is set on the top of the egg, which can receive mixed signals of transmitted and reflected light, thus realizing the comprehensive acquisition of optical characteristics of the internal tissue of the egg.

[0020] The egg tray 12 in the base 1 can be of various shapes, such as curved or ring-shaped. The curvature, material, and reflection angle of the egg tray can be adapted to different egg sizes to ensure that light shines evenly into the egg. The light-blocking part 31 can be a light-blocking plate or a light-blocking cavity, etc., and is made of light-blocking material. The reflective surface 11 is located below the equator of the egg.

[0021] In some cases, the base 1, the light source area 2, and the focusing area 3 can all be modular structures, which can stably collect transmission spectrum signals in the early, middle, and late stages of egg incubation, avoiding the defects of reduced transmittance and severe signal attenuation in the later stages of other irradiation methods, and achieving high-precision and repeatable spectral acquisition.

[0022] Fertilized eggs can be distinguished by sex; specifically, the sex of the chicken that hatches from the egg is the sex of the egg itself.

[0023] In this embodiment, the reflection from the base 1 allows a portion of the light emitted from the light source 21 to penetrate the egg and be collected by the focusing area 3, while another portion of the light is reflected from the bottom and re-transmitted. This results in one or even multiple reflections of the light within the egg, enhancing the signal strength and forming an enhanced composite optical path. This effectively addresses the problem of decreased light transmittance during the later stages of incubation. The use of a light-blocking section 31 blocks direct light interference, ensuring the purity of the collected light from the transmission path and improving the signal-to-noise ratio.

[0024] In some optional implementations of any embodiment of this disclosure, the egg tray is curved, the edge of the light-receiving opening 32 is used to contact the egg to be tested, and the egg tray 12 is used to contact the egg to be tested.

[0025] The eggs are fixed in two directions, up and down, through the light-collecting opening 32 and the egg tray 12, which achieves a better fixation effect and helps to improve the stability of the test.

[0026] Optionally, the edge material is an elastic material, and the surface material of the egg tray 12 includes an elastic material.

[0027] The elastic material can be rubber or leather, etc. The surface material of the egg tray 12 can be entirely elastic or partially elastic. For example, the elastic material of the egg tray 12 can be ring-shaped, with the uppermost edge of the ring connecting to the reflective surface 11.

[0028] These methods, using elastic materials, can improve the fit between the device and the egg, preventing the egg from breaking or light from leaking out.

[0029] In some optional implementations of any embodiment of this disclosure, the egg tray is curved, the light source area 2 is a hollow barrel shape, the sidewall of the focusing area 3 is connected to the sidewall of the light source area 2 to form a top cover that can be placed on the base 1, and the bottom surface of the base 1 is circular.

[0030] The sidewall of the focusing area 3 can be an inclined sidewall, while the sidewall of the light source area 2 can be an upright sidewall. The lower edge of the focusing area 3 can be connected to the upper edge of the light source area 2, for example, they can be integrally formed. The resulting assembly is the upper cover of the base 1. The base can be a solid cylinder.

[0031] Optionally, a protrusion 13 is provided on the outer side of the side wall of the base 1, and the upper edge of the protrusion 13 is higher than the upper surface of the base 1. A placement groove 14 for the protrusion 13 is provided on the outer side of the side wall of the light source area 2. When the upper cover is placed on top of the base 1, if the protrusion 13 is placed in the placement groove 14, the relative position of the upper cover and the base 1 is fixed.

[0032] The protrusion 13 can be of various shapes, such as ear-shaped or columnar. A bracket 22 for the light source 21 can be provided on the side wall of the light source area 2 for fixing the light source 21.

[0033] In some optional implementations of any embodiment of this disclosure, the light emitted by each of the light sources 21 is offset upward in the horizontal direction and aligned with the vertical central axis of the egg to be tested.

[0034] In these implementations, the light is emitted at an angle upwards, and the position of the emitted light is below the equator of the egg.

[0035] By projecting light source 21 obliquely upwards from below the egg's equator and aligning it with the egg's vertical central axis, a longer transmission path of light within the egg can be ensured, thereby improving the richness and accuracy of the collected light signal. Furthermore, the high-reflectivity structure at the bottom allows some of the light that penetrates the egg after being illuminated by light source 21 to be reflected and reused, achieving secondary enhancement of the light path and improving the intensity and stability of the light signal.

[0036] In some optional implementations of any embodiment of this disclosure, the vertical distance between the lower surface of the light-blocking part 31 and the reflective surface 11 is less than the maximum straight-line distance inside the egg to be tested; the distance between the egg to be tested and the light-collecting port 32 is less than the first target proximity distance.

[0037] The smaller size of the egg to be tested and the light-collecting opening 32 reduces light leakage, allowing a larger proportion of the collected light to come from the light transmitted through the egg rather than from the light leaking through the gap between the egg and the light-collecting opening 32, thereby improving the accuracy of the detection.

[0038] In some optional implementations of any embodiment of this disclosure, the distance between the lowest edge of the sidewall of the light source region 2 and the highest edge of the sidewall of the base 1 is less than the second target proximity distance; the egg to be tested is in contact with the egg tray 12.

[0039] These implementations, by limiting the distance between the lowest edge of the sidewall and the highest edge of the sidewall of the base 1, can prevent light from outside the detection device from entering the device, thereby further improving detection accuracy.

[0040] In some optional implementations of any embodiment of this disclosure, the focusing region 3 is connected to a spectrometer, the focusing region 3 is provided with a non-imaging focusing device, the focusing region 3 is used to guide light into the spectrometer, and the focusing region 3 is also provided with an optical fiber bundle or an imaging unit.

[0041] In these implementations, the imaging units can be CCD (Charge-Coupled Device) imaging units. Two-dimensional spectral acquisition can be performed using this imaging unit. The spectrometer can be connected to electronic devices, such as terminal devices, to receive the output results from the spectrometer.

[0042] It can stably obtain transmitted optical signals in the early, middle and late stages of egg incubation, overcoming the defect of severe signal attenuation in the later stage of traditional bottom-transmitted light collection, and achieving high-precision and repeatable spectral acquisition.

[0043] Optical fibers or imaging units can guide light into a spectrometer to enable real-time acquisition and analysis.

[0044] Optionally, the non-imaging focusing device is a Fresnel lens or an integrating sphere structure; the reflective surface 11 is silver-plated, aluminum-coated, or a ceramic microsphere reflective coating.

[0046] Figure 2b A schematic diagram of the external structure of an egg sex detection device according to an embodiment of the present disclosure is shown.

[0047] Figure 3 A schematic diagram of the spectral signal corresponding to the egg sex detection device according to an embodiment of the present disclosure is shown. The multiple control groups Control1, Control2, and Control3 in the diagram represent spectral signals obtained by direct transmission from the bottom without a reflective surface, resulting in lower peak values. The spectral signal of the light collected using this detection device is called Sample, and its peak value is significantly higher than that of each control group. Mean represents the average value of the spectral signal.

[0048] Figure 4 An egg sex detection method according to an embodiment of this disclosure is shown. Figure 4 As shown, the egg sex detection method includes: Step S401: Place the egg to be tested upright on the egg tray of the base, and place the light-focusing area above the egg to be tested so that the upper part of the egg to be tested passes through the light-collecting opening; Step S402: Turn on each light source in the light source area so that each light source shines on the egg to be tested in a horizontally upward direction; Step S403: Collect the light from below the light-collecting opening through the light-focusing area, and use the collected light to detect the sex of the egg to be tested.

[0049] In this embodiment, during detection, the light-collecting opening is located at the top of the egg to be detected, and the egg is passed through the light-collecting opening by the top.

[0050] This embodiment achieves efficient optical signal enhancement by providing a novel optical path structure.

[0051] In some optional implementations of this embodiment of the present disclosure, irradiating the egg to be tested includes: irradiating the egg to be tested so that the light from each light source is transmitted through the egg, or is transmitted through the egg after being reflected by the reflective surface.

[0052] In some optional implementations of this embodiment, collecting light from below the light-collecting port through the focusing area includes: collecting light from below the light-collecting port through a non-imaging focusing device in the focusing area; and detecting the sex of the egg to be tested using the collected light includes: guiding the light collected by the focusing area into a spectrometer connected to the focusing area through an optical fiber bundle or an imaging unit.

[0053] Electronic devices can be used to analyze the spectral information obtained from the spectrometer in order to ultimately determine the sex of the egg.

[0054] In some optional implementations of this embodiment, the base, the light source area, and the focusing area are all modular structures; the method further includes: if the size of the egg to be detected changes beyond a preset change level, the spectral band requirement of the light source changes, and / or the detection accuracy changes, then at least one modular structure in the device is adjusted.

[0055] In these implementations, adjusting the modular structure can involve changing at least one of its components or replacing the modular structure itself.
