Description

TECHNICAL FIELD

[0001] The utility model relates to seed thousand kernel weight determination technical field, especially a kind of seed phenotype equipment. BACKGROUND

[0002] The phenotypic characteristics and thousand kernel weight of seed are important indicators for measuring seed quality, which directly affect the yield and quality of crops, and the evaluation and analysis of seed quality are particularly important for breeding and propagation process. The traditional seed phenotypic characteristic extraction and thousand kernel weight test method mainly relies on manual operation or semi-automatic equipment, which is time-consuming and labor-intensive, and the precision is limited. The current statistical thousand kernel weight method is either manually counting or calculating the weight after machine counting, which is slow, expensive and only suitable for a few varieties. Another way is to place the seed tester above the balance to measure, so that the backlight power supply on the seed tester is connected to the outside world, and the equipment is heavy. At the same time, due to the heavy weight of the seed tester, the detection accuracy of the sensor will be reduced if the range is increased, which affects the measurement accuracy and stability.

[0003] In the prior art, the seed is first counted by hand or machine, and then the thousand kernel weight and phenotype are counted, which is time-consuming and labor-intensive, and the seed counting machine is expensive and only suitable for a few shapes of seeds. The thousand kernel weight and phenotype acquisition conflict, and the phenotype acquisition work needs to be done again. The seed tester is placed above the balance: the backlight power cord on the seed tester is connected to the outside world, which will be related to the outside world, affecting the detection accuracy of the gravity sensor. The equipment is heavy, and due to the heavy weight of the seed tester, the detection accuracy of the sensor will be reduced if the range is increased, which affects the measurement accuracy and stability. All current technical solutions use a backlight panel connected to an external power supply. As long as the power cord is connected to the external power supply, the power cord will affect the sensitivity of the gravity sensor. Since the quality of the seed itself is small, the test result has a large deviation on the thousand kernel weight of the seed. The current method of reducing error by zeroing is not suitable for the test. Therefore, there is an urgent need for a seed phenotype equipment that can directly and quickly and accurately measure the thousand kernel weight and analyze the seed phenotype data, while improving the accuracy and reliability of the detection.

[0026] Seed phenotypic characteristics and thousand-seed weight are important indicators for measuring seed quality, directly affecting crop yield and quality. Seed quality assessment and analysis are particularly important for the breeding and propagation process. Traditional methods for extracting seed phenotypic characteristics and testing thousand-seed weight mainly rely on manual operation or semi-automated equipment. These methods are time-consuming, labor-intensive, and have limited accuracy. Currently, the methods for calculating thousand-seed weight are either manual counting or machine counting followed by weight calculation. Manual counting is slow, and seed counting machines are expensive and only applicable to a few varieties. Another method is to place a seed analyzer above a balance for measurement. This requires the backlight power supply of the seed analyzer to be connected to an external source, and the equipment is bulky. Furthermore, due to the weight of the seed analyzer, increasing the sensor range reduces the detection accuracy, affecting the accuracy and stability of the measurement.

[0027] In existing technologies, the common practice is to count seeds manually or by machine first, and then calculate the thousand-seed weight and phenotype. Manual methods are time-consuming and labor-intensive, while seed counting machines are expensive and can only handle a limited number of seed shapes. Furthermore, counting seeds to determine the thousand-seed weight conflicts with phenotype acquisition, requiring a separate phenotype acquisition process. Placing the seed testing instrument above the balance introduces the problem: the backlight power cord of the instrument is connected to the outside environment, affecting the accuracy of the gravity sensor. The equipment is also bulky, and its weight necessitates increasing the sensor's range, thus reducing accuracy and stability. Current solutions connect the backlight panel to an external power supply. However, this connection affects the sensitivity of the gravity sensor, and since seeds are small, the resulting deviation from the thousand-seed weight measurement is significant. While zeroing methods exist to reduce error, the connection between the backlight panel and the power supply is movable. Although this reduces error somewhat, the disturbance to the test bench during operation still fails to meet the requirements for accurate thousand-seed weight. Therefore, there is an urgent need for a seed phenotyping device that can directly, quickly, and accurately measure thousand-seed weight and analyze seed phenotypic data, while improving the accuracy and reliability of the detection.

[0028] refer to Figs. 1-3 To address the aforementioned issues, this application provides a seed phenotyping device 10, comprising a base 21, a support 22, a camera 30, a light-emitting device 40, a backlight device 50, a platform 60, a tray 70, and a weighing device 80. The base 21 has a first mounting groove 211, and the weighing device 80 is disposed in the first mounting groove 211. The platform 60 is disposed on the weighing device 80, and the backlight device 50 is disposed on the side of the platform 60 away from the weighing device 80. The tray 70 is disposed on the backlight device 50 and is used to place seeds 100. The support 22 is connected to the base 21, and the camera 30 is connected to the support 22 and located above the backlight device 50. The imaging surface of the camera 30 faces the side of the platform 60 where seeds 100 are placed. The light-emitting device 40 is connected to the camera 30, and the light-emitting surface of the light-emitting device 40 faces the backlight device 50.

[0029] refer to Figs. 1-3 In this seed phenotyping device 10, Fig. 1 This is a schematic diagram of the structure of a seed phenotype device 10 provided in an embodiment of this application. Fig. 2 This is a schematic diagram of the structure of a seed phenotype device 10 provided in an embodiment of this application. Fig. 3This is a cross-sectional view of a seed phenotyping device 10 provided in one embodiment of this application. The seed phenotyping device 10 includes a base 21, a support 22, a camera device 30, a light-emitting device 40, a backlight device 50, a platform 60, a tray 70, and a weighing device 80. The base 21 can be placed on a test platform, and the base 21 has a first mounting groove 211 in which the weighing device 80 is disposed. In some embodiments, the base 21 can adopt a hollow shell structure, and multiple feet 224 can be provided on the bottom of the base 21. The feet 224 can be made of a soft material, such as rubber, which has the advantages of strong anti-slip properties and good durability, and can increase the stability of the seed phenotyping device 10 when placed. Silicone feet 224 can also be used, which has the advantages of soft texture and easy height adjustment. Currently, all technical solutions connect the backlight panel 51 to an external power supply. However, this connection affects the sensitivity of the gravity sensor 81. Since the mass of the seeds 100 is small, the test results show a significant deviation in the thousand-seed weight. While some methods use zeroing to reduce error, the connection between the backlight panel 51 and the power supply is movable. Although this reduces the error somewhat, the operation disturbs the test bench, resulting in an error that still cannot meet the requirements for thousand-seed weight. To address the shortcomings of existing technologies, the seed phenotyping device 10 provided in this application includes a weighing device 80 with a platform 60. A backlight device 50 is located on the side of the platform 60 away from the weighing device 80, and a tray 70 is placed on the backlight device 50 for holding the seeds 100. In some embodiments, a seed box is placed on the tray 70 for holding the seeds 100. The backlight device 50 is placed on the platform 60, and the platform 60 is placed on the weighing device 80, which solves the problem that traditional phenotypic acquisition devices cannot collect weight, and improves the accuracy and reliability of the detection.

[0030] refer to Figs. 1-3In some embodiments, the camera device 30 is connected to the bracket 22 and located above the backlight device 50. The shooting surface of the camera device 30 faces the side of the shelf 60 where the seeds 100 are placed. The camera device 30 can capture images of the seeds 100 in the tray 70. In some embodiments, machine vision algorithms can be applied to the images of the seeds 100 in the tray 70 acquired by the camera device 30 to detect the number of seeds 100. Then, mathematical calculations are performed with the measured mass of the seeds 100 to obtain an approximate thousand-seed weight value. The seed 100 images can be segmented using machine vision algorithms to obtain an image of each seed 100 and extract the size, color, and texture features of the seeds 100 based on the images. The seed 100 images, seed 100 size, color, texture features, and weight are then uploaded to the cloud via an IoT module (wireless communication module). Since the thousand-seed weight calculation requires acquiring 1000 seeds 100 at a time, multiple operations are required, accumulating the number and weight of the seeds 100 each time to calculate the thousand-seed weight. In some embodiments, the light-emitting device 40 is connected to the camera device 30, with the light-emitting surface of the light-emitting device 40 facing the backlight device 50. Both the light-emitting device 40 and the camera device 30 are downward-facing. The camera device 30 captures images of the tray 70 on the backlight panel 51, and the light-emitting device 40 illuminates the seed box on the backlight. In some embodiments, the light-emitting device 40 is arranged around the camera device 30, which helps ensure sufficient light during the camera device 30's imaging and improves the clarity of the images acquired by the camera device 30. By acquiring images of the seeds 100 inside the seed box through the camera and obtaining the mass of the seeds 100 through the gravity sensor 81, the analysis of the thousand-seed weight and seed phenotypic data of the seeds 100 can be performed quickly and accurately, while improving the accuracy and reliability of the detection.

[0031] refer to Figs. 1-3In some embodiments, the weighing device 80 includes a gravity sensor 81 and a sensor mounting plate 82. The gravity sensor 81 is a sensor capable of sensing changes in gravity. It detects the device's attitude and motion state in three-dimensional space by measuring changes in acceleration. The gravity sensor 81 operates based on principles such as piezoelectric or capacitive effects. When the device accelerates or decelerates, the crystal or medium inside the sensor deforms, generating a voltage, which is converted into an electrical signal output through relevant circuitry. The sensor mounting plate 82 is connected to the bottom of the first mounting groove 211. The gravity sensor 81 is located on the side of the sensor mounting plate 82 opposite to the bottom of the first mounting groove 211, which helps improve the structural compactness of the seed phenotype device 10. The sensor mounting plate 82 is a support structure for fixing the internal components of the gravity sensor 81 and can be made of metal. The sensor mounting plate 82 secures the various components inside the weighing device 80 together with screws or other fasteners, ensuring that the weighing device 80 does not shift during operation. The sensor mounting plate 82 also protects the sensitive components and circuits inside the weighing device 80 from interference and damage from the external environment, ensuring that the various components inside the sensor can be stably fixed together, thereby ensuring the normal operation of the weighing device 80.

[0032] refer to Figs. 1-3 In some embodiments, the backlight device 50 includes a backlight panel 51 and a backlight power supply 52. ​​The backlight power supply 52 is located at the edge of the shelf 60, and the backlight panel 51 is located in the middle area of ​​the shelf 60. The backlight power supply 52 is electrically connected to the backlight panel 51, and the tray 70 is placed on the backlight panel 51. The backlight panel 51 provides a bottom light source for the tray 70, which helps the camera device 30 to acquire a clearer image of the seed 100. In some embodiments, the backlight panel 51 can be made of transparent fiberglass or a plastic plate containing phosphors to provide background illumination for the shelf 60, ensuring clear visibility of the image in dark environments. The working principle of the backlight panel 51 is to evenly distribute the light emitted by the light source onto the shelf 60 through the transparent fiberglass and plastic plate, while the phosphors are responsible for converting the light emitted by the light source into visible light. This design allows the backlight panel 51 to provide stable lighting effects in various environments. In some embodiments, a backlight is installed on the backlight panel 51. By integrating components such as a high-precision weighing device 80, a platform 60, a backlight device 50, a seed box, and a light-emitting device 40, the compactness between the various structures of the seed phenotyping device 10 is improved, enabling automated extraction of seed phenotypic characteristics and rapid measurement of thousand-seed weight.

[0033] refer to Figs. 1-3In some embodiments, the bracket 22 includes a vertical section 221, an inclined section 222, and a horizontal section 223 connected in sequence. One end of the vertical section 221 is connected to the edge of the base 21, and the end of the horizontal section 223 away from the inclined section 222 is connected to the camera device 30. The bracket 22 provides support and connects the camera device 30 and the base 21. In some embodiments, the seed phenotyping device 10 also includes an integrated display 90, which is mounted on the base 21. In some embodiments, the integrated display 90 can also be mounted on the bracket 22. The integrated display 90 integrates the host and monitor of a traditional desktop computer into a single unit, simplifying computer use and making the device neater. The integrated display 90 typically only requires a keyboard and mouse connected to the monitor for normal operation. The back of the integrated display 90 is connected to the inclined section 222, and the inclined mounting of the integrated display 90 facilitates user observation.

[0034] refer to Figs. 1-3 In some embodiments, the support 22 includes a first telescopic frame and a second telescopic frame that are movably connected. The portion of the first telescopic frame away from the second telescopic frame is fixed to the base 21, and the end of the second telescopic frame away from the first telescopic frame is connected to the camera device 30. The height of the first and second telescopic frames can be easily adjusted. In some embodiments, the tray 70 can be transparent to facilitate observation of the seed 100's placement and to allow the camera device 30 to obtain clearer images of the seeds 100. For example, a polypropylene tray 70 can be used, which is relatively inexpensive and helps reduce equipment manufacturing costs. Alternatively, a fiberglass transparent tray 70 can be used, which has the advantages of high strength and high toughness. In some embodiments, the seed box can also be made of a transparent material. For example, a plastic seed box has good plasticity and water resistance, strong impact resistance, high transparency, and low cost.

[0035] refer to Figs. 1-3In the seed phenotyping device 10, when collecting the weight of 1000 seeds and the phenotypic characteristics of 100 seeds, the seed box is first placed on the tray 70 of the platform 60 and the device is zeroed. Then, the seeds 100 are placed in the seed box, the backlight device 50 and the light-emitting device 40 are turned on, the image of the seeds 100 in the seed box is acquired by the camera device 30, the mass of the seeds 100 is acquired by the gravity sensor 81, the number of seeds 100 is detected by the machine vision algorithm, and then mathematical calculations are performed with the mass of the seeds 100 measured at this time to obtain an approximate weight of 1000 seeds. The image of the seeds 100 is segmented by the machine vision algorithm to obtain an image of each seed 100 and the size, color and texture features of the seeds 100 are extracted based on the image. The image of the seeds 100, the size, color, texture features and weight of the seeds 100 are uploaded to the cloud through the IoT module (wireless communication module). Since the thousand-grain weight measurement requires obtaining 1000 seeds per operation, multiple operations are needed. Each operation accumulates the quantity and weight of seeds to calculate the thousand-grain weight. The above process can directly, quickly, and accurately perform the analysis of the thousand-grain weight and seed phenotypic data, while improving the accuracy and reliability of the detection.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
