Description

Technical Field

[0001] This application relates to the field of root analysis equipment technology, and in particular to a plant root analysis device. Background Technology

[0002] For a long time, botanists have conducted extensive research on the structure, function, and regulation of the photosystem in aboveground plant organs, achieving significant progress. However, due to limitations in research methods and working conditions, research on plant root systems lags far behind that on aboveground parts. Visual monitoring and analysis of plant roots facilitates in-depth research on the morphology, physiological characteristics, ecotypes, varietal differences, and the influence of environmental factors on root systems. Furthermore, it is of great significance for studying root water absorption mechanisms and establishing theoretical, semi-theoretical, semi-empirical, and empirical models to describe root water absorption. Based on key data on root growth, experimental parameters and methods can be provided to develop ways to maintain optimal plant growth.

[0003] Existing root analysis equipment utilizes scanners or document cameras to acquire high-resolution color or black-and-white images of plant roots. These high-quality root images are then analyzed to obtain morphological phenotypes related to crop roots and root nodules.

[0004] In related technologies, root analysis equipment can only acquire images from a single direction and cannot acquire information on root nodules in the back-shaded part. The image acquisition throughput is low and the time consumption is long, which does not meet the timeliness requirements of root phenotypic identification. Furthermore, the water change of the imaging disc is done manually, which is inconvenient to operate and easily spills water on the instrument and the table. Utility Model Content

[0005] Based on this, it is necessary to provide a plant root analysis device to address the problems of traditional root analysis devices, which can only acquire images from a single direction and cannot acquire information on root nodules in the back-shaded parts, have low image acquisition throughput, are time-consuming, do not meet the timeliness requirements of root phenotypic identification, and require manual water changing of the imaging disc, which is inconvenient to operate and easily spills water on the instrument and table.

[0006] According to one aspect of this application, a plant root analysis device is provided, comprising: an operating frame including a transparent placement platform; at least one support member disposed on the placement platform, the support member being used to load plant roots for which information to be collected; and a data acquisition device movably disposed relative to the operating frame along a first direction, the data acquisition device being used to acquire images of the plant root system.

The second acquisition camera is located on the side of the placement platform facing the direction of gravity and is used to acquire images of the plant roots on the side facing the direction of gravity.

[0008] In one embodiment, the plant root analysis device further includes a water exchange system, which is disposed on the operating frame and connected to one or more of the support components, with the water exchange system located on one side of the corresponding support component;

[0009] In one embodiment, the water exchange system includes a support pipe, an inlet pipe, and a drain pipe mounted on the operating frame. The support pipe is also provided with an equipment compartment, and a portion of the support pipe, the inlet pipe, and the drain pipe extends into the equipment compartment. The support pipe located in the equipment compartment is connected to the inlet pipe and the drain pipe located in the equipment compartment, respectively.

[0010] In one embodiment, a first control valve is installed on the inlet pipe, and a second control valve is installed on the drain pipe.

[0011] In one embodiment, the plant root analysis device further includes a ground track system extending along the first direction, a drive mechanism is provided on the mobile frame, the acquisition device and the ground track system are movably connected along the first direction, and the drive mechanism is used to drive the acquisition device to move back and forth on the ground track system.

[0012] In one embodiment, the mobile frame is further provided with a suspension located above the placement platform, the suspension is equipped with a tag reading device, and the placement platform is further provided with a tag placement position corresponding to the carrier.

[0013] In one embodiment, the placement platform is made of acrylic sheet.

[0014] In one embodiment, one or more light source groups are installed on the side of the mobile frame facing the operating frame. In the same light source group, the light source group includes a first light source and a second light source. The first light source is located on the side of the placement platform away from the direction of gravity and is disposed towards the placement platform. The second light source is located on the side of the placement platform facing the direction of gravity and is disposed towards the placement platform.

[0015] In one embodiment, a light shield is installed at the end of the mobile frame that is away from gravity, located above the placement platform, and the first acquisition camera and the first light source are both located inside the light shield.

[0016] In one embodiment, the placement platform is further provided with at least one set of limiting bosses, and one set of limiting bosses includes multiple limiting bosses. The carrier is detachably mounted on the placement platform through the limiting bosses.

[0017] In one embodiment, the operating frame is further provided with a control panel, and two protective devices are provided on the outer wall of the operating frame on the side opposite to the direction of gravity, which are opposite to each other along the first direction.

[0018] This application has the following beneficial effects:

[0019] This device enables simultaneous front and back image acquisition of the sample using a first and second acquisition camera, capturing images from both sides simultaneously. Compared to traditional equipment, this device offers more comprehensive acquisition results and higher research value. Furthermore, throughout the acquisition process, the drive mechanism propels the acquisition equipment continuously along the ground track system, with the acquisition time for a single component not exceeding 5 seconds, significantly shorter than the 1-2 minutes acquisition time of existing scanners, thus better meeting timeliness requirements. The one-button automatic water replacement system greatly reduces manual operation, preventing water spillage on the instrument and work surface while improving acquisition efficiency and quality.

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0033] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0034] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0037] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0038] See appendix Figure 1 - Appendix Figure 2 The operating frame 1 can have a first direction x, a second direction y, and a third direction, all of which are different. The first direction x and the second direction y can be any two different directions parallel to the placement platform 2, and the third direction can be parallel to the direction of gravity. For example, the first direction x, the second direction, and the third direction can be perpendicular to each other. For example, the first direction x can be the length direction of the operating frame 1, the second direction can be the width direction of the operating frame 1, and the third direction can be the thickness direction of the operating frame 1. The length, width, and thickness in the embodiments of this application are merely for descriptive convenience and do not imply any limitation on the dimensions. For example, the width can be greater than, equal to, or less than the length.

[0039] See appendix Figure 1 - Appendix Figure 5 , Figure 1 - Appendix Figure 2 A schematic diagram of the overall structure of a plant root analysis device according to an embodiment of this application is shown, including an operating frame 1 and a transparent placement platform 2;

[0040] At least one carrier 3 is set on the placement platform 2, and the carrier 3 is used to load the plant root system to collect information;

[0041] The acquisition device 5 is movably set relative to the operating frame 1 along the first direction, and the acquisition device 5 is used to acquire images of plant roots;

[0042] The acquisition device 5 includes a mobile frame 501, on which a first acquisition camera 503 and / or a second acquisition camera 504 are mounted. The first acquisition camera 503 is located on the side of the placement platform 2 away from the direction of gravity and is used to acquire images of the plant roots on the side away from the direction of gravity. The second acquisition camera 504 is located on the side of the placement platform 2 facing the direction of gravity and is used to acquire images of the plant roots on the side facing the direction of gravity.

[0043] This application involves setting one or more carriers 3 on a transparent placement platform 2 of the operating frame 1, and acquiring images of the plant system placed in the carrier 3 using a first acquisition camera 503 and / or a second acquisition camera 504. The first acquisition camera 503 is used to acquire images of the front of the plant roots, and the second acquisition camera 504 is used to acquire images of the back of the plant roots. The first acquisition camera 503 or the second acquisition camera 504 can individually acquire single-sided images of the plant roots, or they can jointly acquire double-sided images of the plant roots.

[0044] In some embodiments, the plant root analysis device further includes a water exchange system 301, which is disposed on the operating frame 1, for example, on the placement platform 2, located on one side of the corresponding support member 3, and connected to one or more support members 3.

[0045] Specifically, there are one or more water exchange systems 301, each corresponding to at least one carrier 3, used to replenish and / or drain water from the carrier 3. When an appropriate amount of water is injected into the carrier 3, it helps the plant root sample to quickly separate the overlapping lateral roots in the carrier 3, so that the entire root system is distributed in a divergent manner, which is beneficial for root image acquisition and feature recognition.

[0046] In some embodiments, water may not be injected into the carrier 3 or the water in the carrier 3 may be drained, and samples for which front and back images need to be collected, such as plant stems and leaves, may be placed directly.

[0047] See appendix Figure 2 - Appendix Figure 4The water exchange system 301 includes a support pipe 302, an inlet pipe 304, and a drain pipe 305 mounted on the operating frame 1. The support pipe 302 is also provided with an equipment compartment 303. Parts of the support pipe 302, the inlet pipe 304, and the drain pipe 305 extend into the equipment compartment 303. The support pipe 302 located in the equipment compartment 303 is connected to the inlet pipe 304 and the drain pipe 305 located in the equipment compartment 303, respectively.

[0048] In some embodiments, the support pipe 302 is made of a rigid material and is connected to an external clean water source and a wastewater collection tank. When water needs to be changed, the water pump connected to the wastewater collection tank is started, and wastewater is drawn into the wastewater collection tank through the drain pipe 305. Then, the water pump connected to the external clean water source is started, and the external clean water is injected into the carrier 3 through the support pipe 302 and the inlet pipe 304.

[0049] See appendix Figure 2 - Appendix Figure 4 A first control valve 306 is installed on the inlet pipe 304, and a second control valve 307 is installed on the drain pipe 305.

[0050] In some embodiments, during use, broken roots, fallen root nodules, and impurities from plant root samples may remain inside the carrier 3. Excessive accumulation of residue after prolonged use can affect subsequent image acquisition and feature recognition of plant root samples. The carrier 3 is cleaned by automatically filling and draining water using the water exchange system 301.

[0051] In some embodiments, the control panel 7 is connected to the first control valve 306 and the second control valve 307. The control panel 7 can independently control the opening and closing of the inlet pipe 304 and the drain pipe 305. When water needs to be changed, the second control valve 307 is activated and the first control valve 306 is closed. At this time, the wastewater in the carrier 3 is discharged to the outside of the equipment through the drain pipe 305 and the support pipe 302. Then, the first control valve 306 is activated and the second control valve 307 is closed. At this time, clean water from outside is injected into the carrier 3 through the support pipe 302 and the inlet pipe 304. When the water level in the carrier 3 reaches a preset height, the control panel 7 controls both the second control valve 307 and the first control valve 306 to be in the closed state.

[0052] This device can automatically change the water in the tank with just one button, improving water changing efficiency and reducing the risk of unnecessary damage to the equipment caused by water spillage.

[0053] In some embodiments, the water-absorbing end of the drain pipe 305 is located inside the support member 3 and fits against its inner wall. This design can improve the drainage effect and avoid wastewater residue. Since the support member 3 needs to be installed from top to bottom, in order to avoid interference from the inlet pipe 304 and the drain pipe 305, the ends of the inlet pipe 304 and the drain pipe 305 are made of flexible materials, such as rubber.

[0054] See appendix Figure 1 - Appendix Figure 2 The operating frame 1 also includes a ground rail system 4 extending along the first direction x. A drive mechanism 502 is provided on the moving frame 501. The acquisition device 5 and the ground rail system 4 are movably connected along the first direction. The drive mechanism 502 is used to drive the acquisition device 5 to move back and forth on the ground rail system 4.

[0055] In some embodiments, the acquisition device 5 is installed on the ground rail system 4. When acquiring plant root images, the drive mechanism 502 drives the acquisition device 5 to move along the ground rail system 4.

[0056] Among them, the acquisition device 5 uses a linear array camera to perform scanning image acquisition. The first acquisition camera 503 and the second acquisition camera 504 jointly acquire images of the front and back of the plant root system to obtain more comprehensive phenotypic information of the plant root system. In particular, it can identify the root nodule image information that is obscured at the bottom of the plant root system, providing strong supporting data for breeders to study rhizobia.

[0057] See appendix Figure 1 - Appendix Figure 2 and attached Figure 5 The mobile frame 501 is also equipped with a suspension 505 located above the placement platform 2. A tag reading device 506 is installed on the suspension 505. The placement platform 2 is also equipped with a tag placement position 9 for placing tags corresponding to the carrier 3. The tag reading device 506 includes a barcode scanner or an RFID reader, and the tags include QR codes, barcodes, or radio frequency identification (RFID) tags.

[0058] In some embodiments, when collecting plant root images, the tag reading device 506 reads the tag at the tag placement position 9 corresponding to the carrier 3 to obtain the plant root sample information to be collected, which corresponds to the sample image collected by the collection device 5, thereby improving the efficiency and accuracy of sample information input and processing and realizing the traceability of sample information.

[0059] See appendix Figure 1 - Appendix Figure 3 The placement platform 2 is made of acrylic sheet.

[0060] In some embodiments, the placement platform 2 is made of high-transparency acrylic sheet. High-transparency acrylic sheet has good transparency, chemical stability and good comprehensive mechanical properties. Its light transmittance is above 92%, which can not only ensure that the second acquisition camera 504 can acquire clear images, but also provide sufficient load-bearing capacity to support the installation of the support component 3.

[0061] See appendix Figure 5 Multiple light source groups are installed on the side of the mobile frame 501 facing the operating frame 1. In the same light source group, the light source group includes a first light source 507 and a second light source 508. The first light source 507 is located on the side of the placement platform 2 away from the direction of gravity and is set towards the placement platform 2. The second light source 508 is located on the side of the placement platform 2 facing the direction of gravity and is set towards the placement platform 2.

[0062] In some embodiments, the first acquisition camera 503 and the second acquisition camera 504 are designed to be staggered in the horizontal direction. The first light source 507 and the second light source 508 lighting system are installed on the sides of both the first acquisition camera 503 and the second acquisition camera 504 to avoid insufficient brightness or shadows in the image during image acquisition due to insufficient or uneven lighting, thus effectively ensuring the acquisition of high-quality images.

[0063] See appendix Figure 1 - Appendix Figure 2 The end of the mobile frame 501 that is away from gravity is equipped with a light shield 509 located above the placement platform 2. The first acquisition camera 503 and the first light source 507 are both located inside the light shield 509.

[0064] In some embodiments, when collecting image information of plant roots, the light shield 509 prevents light or light from above the platform 2 from entering the first acquisition camera 503 and interfering with it, thereby further improving the quality of the images acquired by the first acquisition camera 503.

[0065] In some embodiments, when collecting image information of plant roots, since the operating frame 1 is a semi-enclosed structure and the moving frame 501 will block the second acquisition camera 504 and the second light source 508 during operation, the light or light source located below the placement platform 2 will not enter the second acquisition camera 504 and interfere with it, thereby further improving the quality of the images acquired by the second acquisition camera 504.

[0066] See appendix Figure 2 - Appendix Figure 3 The placement platform 2 is also provided with at least one set of limiting bosses. A set of limiting bosses includes multiple limiting bosses 8. The carrier 3 is detachably installed on the placement platform 2 along the direction of the operating frame 1 through the limiting bosses 8.

[0067] In some embodiments, the carrier 3 serves as a carrier for the root sample and is fixed on the placement platform 2. The carrier 3 has a water tank structure, and the limiting boss 8 corresponding to the carrier 3 limits the carrier 3 to a preset position on the placement platform 2, so that the carrier 3 is located in the image acquisition area of ​​the acquisition device 5, while preventing the carrier 3 from moving or slipping relative to the placement platform 2 during the image information acquisition operation of the plant root system.

[0068] In some embodiments, the carrier 3 is placed between the limiting bosses 8, which can limit the carrier 3 in the horizontal direction. When installing the carrier 3, it can be installed from top to bottom relative to the placement platform 2.

[0069] See appendix Figure 1 - Appendix Figure 2 The operating frame 1 is also equipped with a control panel 7. On the outer wall of the operating frame 1 on the side opposite to the direction of gravity, there are two protective devices 6 that are opposite each other along the first direction x.

[0070] In some embodiments, two protective devices 6 are disposed opposite to each other at both ends of the operating frame 1 along the first direction X. Specifically, the two protective devices 6 respectively include a light-emitting unit and a light-receiving unit of a photoelectric sensor assembly, used to detect whether an object enters the working area during the root system image acquisition operation, so as to ensure the safety of personnel and equipment.

[0071] In some embodiments, a control panel 7 structure is designed to facilitate operator control of the equipment. When the data acquisition device 5 reciprocates along the ground rail system 4 and is located at both ends of the operating frame 1, the data acquisition device 5 is limited by a limiting device (not shown in the figure).

[0072] To prevent collisions and damage to the data acquisition device 5, a flexible material is also fitted on the outer wall of the limiting device.

[0073] This application employs a placement platform 2 to support a carrier 3 containing plant root samples. An image acquisition device 5 automatically and at high speed acquires single-sided or double-sided photographs of the plant roots, automatically performing image preprocessing and segmentation calculations to obtain phenotypic parameters related to the roots and root nodules, thus improving the efficiency and accuracy of plant root information acquisition. Simultaneously, the tag reading device 506 and water exchange system 301 significantly reduce manual operation intensity and improve the efficiency and quality of data entry and analysis.

[0074] 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.

[0075] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
