Description

Technical Field

[0001] The utility model relates to the field of plant tissue and germplasm resource information identification, in particular to a detection device for seeds and plant tissues. Background Art

[0002] The thousand-grain weight of seeds refers to the weight of one thousand grains, which is of great significance in reflecting the size and fullness of seeds. The thousand-grain weight of seeds is a key indicator for measuring seed quality and high-yield performance, an important criterion for evaluating varieties and management techniques, and an indispensable data in quantitative genetic research. However, for a long time, the thousand-grain weight of grain and oilseeds has been measured manually, which is not only time-consuming and labor-intensive, but also prone to errors due to tedious and repetitive operations that cause fatigue. Traditional manual methods are not only inefficient, but also lead to inaccurate measurement results.

[0003] In addition, seed volume, length and width, as well as the length and weight of plant tissues such as roots, stems and leaves are of great significance for plant research and agricultural production. Seed volume, length and width are key indicators for evaluating seed morphological characteristics. These indicators directly affect the germination rate, germination force and growth potential of seeds, and are therefore very important in selecting seed varieties and evaluating variety quality. However, traditional measurement methods often require manual operation, including the use of calipers and microscopes to measure size and morphological parameters, which is not only time-consuming and labor-intensive, but also prone to human errors. Traditional measurement methods are often cumbersome and troublesome, requiring a lot of manual labor and complex measuring equipment.

[0004] In addition, the length and weight measurements of plant tissues are also of great significance in ecological and biological research. For example, the length and weight of roots, stems and leaves can reflect the growth status, biomass and nutritional status of plants. These measurement data are of great value for understanding the physiological and ecological characteristics, adaptability and biological growth laws of plants. However, traditional measurement methods rely on manual operation and professional equipment, which is not only cumbersome but also easily interfered by human factors.

[0005] Publication number: CN103308430A, discloses a method for measuring the thousand-grain weight of seeds, including: 1) tiling multiple seeds to be tested, and collecting images and weights of the seeds; 2) converting the images into grayscale images, and filtering the grayscale images; 3) binarizing the filtered grayscale images to obtain a binary image; 4) extracting the contour lines of the seeds in the binary image, and dividing them into connected areas according to the contour lines, selecting feature points on the contour lines in each connected area, matching feature point pairs, and establishing a segmentation line between two feature point pairs, wherein the segmentation line divides the connected area into multiple sub-areas; 5) counting the number of sub-areas in all connected areas to obtain the number of the seeds; 6) calculating the thousand-grain weight of the seeds according to the number and weight of the seeds. A device for measuring the thousand-grain weight of seeds is also disclosed. However, this utility model patent also has certain drawbacks. When weighing, it mainly spreads the seeds manually, and some seeds may be stacked, causing information recognition errors and reducing the accuracy and efficiency of reading data. It has a low degree of automation, and the intelligent identification of seed thousand-grain weight information has certain limitations.

[0006] Therefore, developing a simple and efficient measurement method or equipment is of great significance for determining seed volume, grain length and width, as well as the length and weight of plant tissues such as roots, stems and leaves.

[0007] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the utility model, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art known to ordinary technicians in this field.

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] Embodiment 1:

[0043] like Figure 1 , Figure 2 As shown, the device for detecting seeds and plant tissues includes a detection box 1 and a seed sampler 2 used in conjunction therewith.

[0044] Specifically, the detection box 1 includes a housing 11, a weighing module 12, a transparent plate 13, a camera module 14, and a controller 15; the housing 11 may be a rectangular box-type structure, and reference may be made to various current detection cabinet devices. In this embodiment, the top of the housing 11 is open, mainly for placing seeds or plant tissues. The bottom of the housing 11 is connected to a plurality of universal wheels for easy movement. A display screen, control buttons, etc. may also be provided on the front side of the housing 11.

[0045] In this embodiment, the detection box 1 further includes a voltage-stabilized power supply 18 to provide power to various devices.

[0046] The weighing module 12 is fixed inside the housing 11. Specifically, the weighing module 12 includes a pressure sensor 121 and a bracket 122. The pressure sensor 121 is fixedly connected to the housing 11. The pressure sensor 121 can be connected and fixed to the housing 11 by means of a support plate or the like. The bracket 122 is connected to the pressure sensor 121. The pressure sensor 121 is preferably connected to the center of the bracket 122. The bracket 122 can be a rectangular box-shaped structure, the top of the bracket 122 is open, and the bottom of the object-carrying transparent plate 13 is connected to the top opening of the bracket 122 through a suction cup. The bracket 122 can also be a flat plate at the bottom, and four columns are connected to the four corners of the bottom rectangular flat plate to form four supporting points. The bottom of the object-carrying transparent plate 13 is connected to the top opening of the bracket 122 through a suction cup. The function of the bracket 122 is, on the one hand, to serve as a support body for the object-carrying transparent plate 13, and on the other hand, to leave space for placing the camera 142. The pressure sensor 121 can accurately measure the weight information of seeds or plant tissues, with a weighing level of 0.001g.

[0047] The object-carrying transparent plate 13 is preferably a glass plate, which has high light transmittance and does not affect the camera module 14 in collecting information about the measured object.

[0048] The camera module 14 includes a telescopic rod 141 and a camera 142 located on the side of the carrier transparent plate 13. The bottom of the telescopic rod 141 is fixedly connected to the shell 11. The telescopic rod 141 can be fixed to the outside of the shell 11 by bolts or the like so as not to affect seed recovery. The camera 142 is connected to the top of the telescopic rod 141. The camera module 14 also includes a separate camera 142, and the separate camera 142 is located below the carrier transparent plate 13. In this embodiment, the camera 142 is a 3D camera, and there are three of them with a depth perception function. Two of the telescopic rods 141 with cameras 142 can achieve 360-degree photography and information collection of objects by setting different telescopic heights during operation. A 3D stereo image can be formed through subsequent software processing to obtain information such as the space and volume of seeds or plant tissues. Figure 1 As shown, the cameras 142 are mainly located on the left side and the rear side of the object-carrying transparent plate 13 and below the object-carrying transparent plate 13. The number of cameras 142 can be increased as needed.

[0049] like Figure 2As shown, the seed sampler 2 includes a loading plate 21, a sample delivery plate 22, and a partition 23. The loading plate 21 includes a plurality of seed holes 211, and the seed holes 211 are arranged in a matrix. The seed holes 211 on different loading plates 21 have different shapes and sizes, and the seed holes 211 are roughly the same as the particle size and shape of the detected seeds. For example, if the detected seeds are kidney beans, the maximum length is 1.5 cm, and the kidney beans are waist-shaped, then the maximum size of the seed hole 211 is also about 1.5 cm, and the shape is waist-shaped. It is subject to the inability to accommodate two seeds. It can ensure that one seed hole 211 can only accommodate one seed.

[0050] The sample delivery plate 22 includes a plurality of seed channels 221, which are relatively large in size to facilitate the dropping of seeds. After the loading plate 21 and the sample delivery plate 22 are stacked by the magnetic structure 24, the seed holes 211 correspond to the positions of the seed channels 221, and a partition plate 23 is inserted between the loading plate 21 and the sample delivery plate 22.

[0051] In order to facilitate the insertion and extraction of the partition 23, the two sides of the bottom surface of the loading plate 21 are convex downwards and / or the two sides of the top surface of the sample delivery plate 22 are convex upwards, and the loading plate 21 and the sample delivery plate 22 are attached to form a space for accommodating the partition 23. The thickness of the partition 23 can be slightly smaller than the height of the space, which is convenient for the insertion and extraction of the partition 23, and can also prevent the partition 23 from running out of the space easily. The partition 23 can also be connected to the loading plate 21 or the sample delivery plate 22 through a slide rail or a slideway to achieve extraction and insertion.

[0052] The magnetic structure 24 is a magnet installed on the bottom surface of the loading plate 21 and the top surface of the sample delivery plate 22. The magnetic structure 24 is used to connect the loading plate 21 and the sample delivery plate 22, and different loading plates 21 can be replaced as needed, which is convenient for assembly and use.

[0053] The magnetic structure 24 may specifically be a magnetic strip. Figure 3 As shown, a plurality of magnetic strips are fixed on the two side protrusions on the bottom surface of the loading plate 21, and fixed on the two side protrusions on the top surface of the sample delivery plate 22. In addition to the above-mentioned magnetic structure 24, the connection between the loading plate 21 and the sample delivery plate 22 can be achieved by means of magnetic buckles or the like.

[0054] In order to facilitate seed taking, a handle is provided on one side of the loading plate 21 and the sample delivery plate 22 .

[0055] When the present embodiment is working, when identifying and collecting information about seeds, the stabilized power supply 18 is turned on, and the machine starts to supply power. The controller 15 selects the seed measurement mode, and simultaneously checks the corresponding measurement of grain length, grain width, thousand-grain weight, seed volume and spatial 3D stereoscopic image.

[0056] Different loading plates 21 are selected according to the particle size of the seeds to be tested. After the loading plate 21 and the sample delivery plate 22 are attached by the magnetic structure 24, the partition 23 is inserted to separate the loading plate 21 from the sample delivery plate 22. The seed sampler 2 is inserted into the seed bag. After the seeds fall into the seed holes 211, it can be tilted to pour out the excess seeds to ensure that there is only one seed on one seed hole 211. The seed sampler 2 with seeds is placed on the transparent plate 13, the partition 23 is pulled out, and the seeds fall from the seed holes 211 along the seed channel 221 onto the transparent plate 13, and the seed sampler 2 is taken away. At this time, the seeds are neatly arranged on the transparent plate 13, and they do not overlap or block each other, so as to facilitate the subsequent generation of a 3D stereoscopic image. After the controller 15 detects the presence of seeds on the transparent carrier plate 13 through the camera 142, it starts working to construct a spatial 3D stereoscopic image. At the same time, it automatically calculates the grain length and width information of each seed based on the scale information. The pressure sensor 121 records the weight of the seeds. All information is transmitted to the controller 15 in real time. Through the algorithm, the seed length, grain width, thousand-grain weight, seed volume and spatial 3D stereoscopic image are obtained in time, and the obtained information is synchronized with the remote terminal in real time.

[0057] The working mode of this embodiment does not require manual arrangement of seeds on the transparent plate 13; the utility model can reduce the process of seed collection and seed arrangement, improve work efficiency, and can obtain weight, grain length, grain width, and shape at one time through the weighing module 12 and the camera module 14. At the same time, the detection device can also detect plant tissues, obtain plant tissue weight, length, and width information, and adapt to the information collection of various plants.

[0058] If the plant tissue information such as plant roots, stems, leaves, etc. is detected, the measurement steps are basically the same as the above-mentioned seed detection process. The main difference is that when the plant tissue is not convenient to be sampled through the seed sampler 2, the plant tissue needs to be manually placed on the transparent plate 13 for information detection. Select the plant tissue measurement mode on the controller 15, and check the corresponding tissue length, tissue width, tissue weight and spatial 3D stereoscopic image information.

[0059] Embodiment 2:

[0060] like Figure 1 As shown, in this embodiment, based on the first embodiment, the detection box 1 further includes an air supply module 16 , and the air supply module 16 includes a blower 161 , an air supply channel 162 , and an air guide plate 163 .

[0061] Specifically, the blower 161 is installed in the shell 11 and is located at the bottom, the air supply channel 162 is connected to the shell 11 and extends upward to the right side of the cargo transparent plate 13, the wind guide plate 163 is connected to the top of the air supply channel 162 and changes the wind direction to the cargo transparent plate 13; the blower 161 is connected to the controller 15.

[0062] The air supply channel 162 can be realized by using the wall of the housing 11, for example, by adding a U-shaped plate and connecting it to the wall on the right side of the housing 11, so as to form the air supply channel 162, and the bottom of the air supply channel 162 is connected to the air outlet of the blower 161. The air guide plate 163 is an arc-shaped plate, and the length of the arc-shaped plate is roughly the same as the width of the housing 11. The air guide plate 163 can change the direction of the wind. The air supply channel 162 can also not use the wall of the housing 11, and directly use a pipe, a rectangular tube, etc. to guide the wind to the right side of the transparent plate 13, and then change the wind direction through the air guide plate 163.

[0063] The air supply module 16 in this embodiment can supply air to the transparent carrier plate 13 to blow away debris when the seed or plant tissue is not being tested. Specifically, under the control of the controller 15, the machine runs a self-test and performs a self-cleaning mode at the same time. The blower 161 starts to work, and the high-pressure gas passes through the air supply channel 162 and changes direction under the action of the air guide plate 163 to quickly blow away the dust on the transparent carrier plate 13. After the camera 142 captures the image of the transparent carrier plate 13 and transmits it to the controller 15, the controller 15 recognizes that there is no contaminant on the transparent carrier plate 13, and the blower 161 stops working, and the pressure sensor 121 automatically returns to zero, ready to detect the seeds to be detected.

[0064] Embodiment three:

[0065] like Figure 1 As shown, in this embodiment, based on the first or second embodiment, the detection box 1 further includes a seed recovery module 17 , and the seed recovery module 17 includes a recovery channel 171 , an inclined plate 172 , and a seed recovery box 173 .

[0066] The recovery channel 171 is located on the opposite side of the air guide plate 163, that is, the recovery channel 171 is located on the left side of the shell 11, and the recovery channel 171 is connected to the shell 11 and extends downward; the inclined plate 172 is connected to the bottom of the recovery channel 171, and a seed recovery box 173 is set at the relatively low end of the inclined plate 172.

[0067] The recovery channel 171 can be realized by using the wall of the housing 11, for example, by adding a U-shaped plate connected to the wall on the left side of the housing 11, thereby forming the recovery channel 171, and the bottom of the recovery channel 171 is closed by the inclined plate 172. The recovery channel 171 can also not use the wall of the housing 11, and directly use a pipe, a rectangular tube, etc. to guide the seeds to the inclined plate 172. The seeds slide on the inclined plate 172 into the seed recovery box 173 by gravity, thereby realizing seed recovery.

[0068] The detection box 1 also includes a baffle 174, which can be connected to the top of the shell 11, or the baffle 174 can be rotatably connected to the top side of the shell 11, or the baffle 174 can be set at the top of the shell 11 and the top side of the shell 11. The baffle 174 at the top of the shell 11 is similar in structure to the air guide plate 163 and is installed at the top of the recovery channel 171. The baffle 174 located on the top side of the shell 11 can rotate. When the seeds are recovered, the baffle 174 is rotated to the side of the carrier transparent plate 13, and the baffle 174 surrounds the carrier transparent plate 13, ensuring that all seeds can enter the recovery channel 171 when the seeds are recovered, and preventing the seeds from being blown to other places.

[0069] The seed recovery module 17 in this embodiment can blow the seeds into the seed recovery box 173 through the air supply module 16 after the seed detection, so as to facilitate the recovery of the seeds. Specifically, after the detection is completed, the controller 15 controls the blower 161 to start working, and the high-pressure gas passes through the air supply channel 162, changes direction under the action of the air guide plate 163, and quickly blows away the seeds on the transparent plate 13 of the object carrier. The blown away seeds enter the seed recovery channel 171 under the action of the baffle 174, and enter the seed recovery box 173 through the inclined plate 172 under the action of gravity. After the camera 142 captures the image of the transparent plate 13 of the object carrier and transmits it to the controller 15, the controller 15 recognizes that there are no seeds on the transparent plate 13 of the object carrier through the camera 142, and the blower 161 stops working, and the pressure sensor 121 automatically returns to zero, ready to detect the next batch of seeds. This is a working cycle until the detection of all batches of seed information is completed.

[0070] The device is provided with a variety of working modes, and can quickly measure the thousand-grain weight, seed volume, seed density, seed length, and the weight, volume, length and density of plant tissues, etc. It is intelligent and efficient. Compared with the prior art, the advantages are modular design, high efficiency, and intelligence. It can reduce the steps of operation, improve work efficiency, perform self-cleaning, and has a high degree of automation. It can perform different tasks and can quickly measure the thousand-grain weight, seed volume, seed density, seed length, and the weight, volume, length and density of plant tissues, etc. It only needs to set the corresponding parameters to work according to the set program. It is intelligent and efficient, and the data can be saved and recorded through a remote terminal.

[0071] It should be noted that the algorithms or software involved can be any from the prior art.

[0072] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
