These terms are mainly used to better describe the present application and its embodiments, and are not intended to limit the indicated devices, elements or components to have a particular orientation, or to be constructed and operated in a particular orientation.

[0090] In addition, the terms "mount", "set", "provided with", "connected", "connected" should be broadly understood.

For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0091] In order to better understand the technical solutions of the present application, please refer to Figure 1 and Figure 2 In order to solve the problem that the plant phenotype platform cannot retain the medicine and water well after spraying according to the measured plant life state parameters and spraying medicine and water according to the plant life state parameters, the present application provides a track type plant phenotype platform, which comprises: a track 1, a traveling mechanism 2, a functional frame 3, a sub-plate 4, a support frame 5, a drug delivery assembly 7 and a retention device 9; the track 1 is arranged around the plant to be measured (the track 1 can be symmetrically arranged around the plant to be measured, or can be asymmetrically arranged, and the number of tracks is not limited); the traveling mechanism 2 comprises a driving assembly 21, which is arranged on the track 1 and can travel along the track 1; the functional frame 3 is arranged on the traveling mechanism 2, and the functional frame 3 and the traveling mechanism 2 can be further connected by a support part to increase stability, and the functional frame 3 comprises at least one connecting assembly 30; the sub-plate 4 is arranged on the outer side of the track 1; the support frame 5 is arranged on the sub-plate 4, and the support frame 5 can be synchronized with the traveling mechanism 2 to travel on the sub-plate 4 through the connecting assembly 30; the drug delivery assembly 7 is arranged on the upper part and the side part of the support frame 5, and is used to provide nutrient solution and water for the plant; the retention device 9 is arranged on the inner side of the support frame 5, and is used to retain nutrient solution and water in the air and air circulation.

[0092] In one embodiment, the retention device 9 can be a tarpaulin. The tarpaulin is made of waterproof and breathable fabric, which is composed of a PTFE membrane, a high-molecular waterproof and breathable material, and a fabric composite. Depending on the product requirements, two-layer composite and three-layer composite can be used to ensure that while water mist and nutrient solution are being applied to the plants, fresh air can flow into the interior of the tarpaulin, while the water mist and nutrient solution mixed in the air cannot be dispersed to the outside through the tarpaulin, thus playing a good retention role.

[0093] like Figure 5 As shown, in one embodiment, the traveling mechanism 2 further includes: at least two driving components 21 and a first connector 22 located between the at least two driving components 21, the first connector 22 connecting the at least two driving components 21; the driving component 21 has a first adapter groove 23 adapted to the track 1.

[0094] In one embodiment, the driving component 21 further includes a first driver ( Figure 5 (Not shown in the diagram) drive gear 24, two driven gears (251, 252), auxiliary gear 26 and two first pulleys 25. The drive gear 24 is located at the end of the output shaft of the first driver. The two driven gears are located on both sides of the drive gear 24. One driven gear 252 directly meshes with the drive gear 24. The auxiliary gear 26 meshes with the drive gear 24 and the other driven gear 251. The two driven gears (251, 252) are located on the top of the two first pulleys 25 and connected to the corresponding first pulleys 25. In the prior art, when the functional frame 3 of the plant phenotyping platform slides on the track 1, a linear motor or magnetic induction is often used to move or change the position of the functional frame 3 on the track 1. However, when using a linear motor, it is necessary to lay an expensive cable chain all over the track 1 and protect the cable chain, which is quite cumbersome. When using a magnetic induction, it is also necessary to cooperate with a magnetic strip or magnetic block. The above driving methods are quite cumbersome. In this embodiment, the first driver cooperates with the gear to transmit power to the pulley. The drive component 21 can slide on the track 1 through the first adapter groove 23 that is adapted to the track 1. This embodiment is more convenient to implement than the above-mentioned prior art and can also save costs.

[0095] In one embodiment, the first driver can be a stepper motor. By changing the order, number, and duration of electrical signals sent to the stepper motor, the operating direction, angle, and speed of the stepper motor are altered. This allows for the control of the first pulley's rotation around the outer ring of the track, achieving precise positioning and facilitating the definition and control of the device's position during active and automatic inspections. The first driver can also be a servo driver, which may utilize a servo motor, a servo hydraulic motor, or other drive mechanisms such as an electromagnetic driver.

[0096] In one embodiment, the connecting component 30 is a rotatable connector. The connecting component 30 rotates to a first angle to connect with the support frame 5, and rotates to a second angle to disconnect from the support frame 5. In one embodiment, the connecting component 30 may be an electrically driven connecting component, a hydraulically driven connecting component, or a pneumatically driven connecting component.

[0097] like Figure 4 As shown, in one embodiment, the connecting component 30 includes a second driver 32, a connecting portion 33, and a rotating portion 34. The second driver 32 is disposed within the support frame 301 of the functional frame 3. One end of the connecting portion is connected to the output shaft of the second driver 32, and the other end of the connecting portion is sleeved with the rotating portion. The rotating portion 34 has a second adapter groove 341 on the side away from the second driver 32. In this embodiment, the connecting component 30 can be rotated to a second angle via the second adapter groove 341, thereby moving the support frame 5. After completing the corresponding task, the functional frame 3 can return to its original position and move the support frame 5, which is convenient to implement. In specific implementation, the positional relationship between the functional frame 3 and the support frame 5 can be determined based on the position sensor or image sensor on the functional frame 3. This invention is not limited to this. When the functional frame 3 and the support frame 5 are in a suitable position, the connecting component 30 rotates and connects with the support frame 5. Figure 4 The rotation of the connecting component 30 is only one possible rotation method; it can also be rotated in other directions, as long as it can rotate and connect to the support frame 5. This invention is not limited to this. In one embodiment, the second driver can be a motor, a servo motor, or a servo driver. The servo driver can be a servo motor, a servo hydraulic motor, or other drive mechanisms such as an electromagnetic driver.

[0098] like Figure 3 As shown, in one embodiment, a hanging rail 35 is provided between the support frames 301, and a sliding column 36 is provided below the hanging rail 35. A detection box 37 is sleeved on the hanging rail 35 and the sliding column 36 and can move along the hanging rail 35 and the sliding column 36. An extension plate 38 is provided at the bottom of the detection box 37, and a detection device 39 is provided at the bottom of the extension plate 38. The detection device 39 is used to detect the plant's growth status. The detection device 39 for detecting the plant's growth status is prior art in the field and can detect various key parameters in plant growth, providing data support for the plant's nutrient solution, medication, water, etc., and will not be described in detail here.

[0099] like Figure 6 and Figure 7 As shown, in one embodiment, the support frame 5 includes multiple sub-frames 50. First fixing members 51 are evenly arranged on both sides of the outer side of the sub-frames 50, and second fixing members 52 are arranged adjacent to the first fixing members 51. Adjacent sub-frames 50 are connected by telescopic connectors 6. The two ends of the telescopic connectors 6 are rotatably installed on the first fixing members 51 and the second fixing members 52, respectively.

[0100] In an embodiment, the sub-frame 50 closest to the functional frame 3 has at least one clamping post 54 which is adapted to the second adaptive slot 341. In this embodiment, the connecting assembly 30 is connected to the clamping post 54 of the sub-frame 50 closest to the functional frame 3, and the connecting assembly 30 can be more tightly connected to the clamping post 54, so as to better drive the movement of the overall support frame 5.

[0101] In an embodiment, the clamping post 54 can be symmetrically arranged on both sides of the sub-frame 50, or can be asymmetrically arranged. One or more clamping posts 54 can be arranged on one side of the sub-frame 50, and the second adaptive slot 341 of the connecting assembly 30 can be connected to any one of the clamping posts 54 as needed, so as to adapt to different positions of the connecting assembly 30.

[0102] In an embodiment, the bottom of the sub-frame 50 also has a second pulley 53 which is adapted to the sliding slot 41 of the auxiliary plate 4. The sliding slot 41 of the auxiliary plate 4 and the second pulley 53 at the bottom of the sub-frame 50 make it easier to move on both sides of the plant, and are less likely to deviate due to terrain.

[0103] As shown in Figure 8 In an embodiment, the telescopic connecting piece 6 includes a first connecting arm 61, a second connecting arm 62, and a third connecting arm 63. One end of the first connecting arm 61 has a first opening 611. The second connecting arm 62 is slidably sleeved in the first connecting arm 61, and can slide out from the other end of the first connecting arm 61. The third connecting arm 63 is slidably sleeved in the second connecting arm 62, and can slide out from the same direction as the second connecting arm 62. The third connecting arm 63 has a second opening 631 at the end away from the first connecting arm 61.

[0104] In one embodiment, the first opening 611 is connected to the first fastener 51 of the subframe 50, and the second opening is connected to the second fastener 52 of the adjacent subframe 50; or the first opening 611 is connected to the second fastener 52 of the subframe 50, and the second opening is connected to the first fastener 51 of the adjacent subframe 50. In this embodiment, when the first driver moves the functional frame 3 and the support frame 5, the spacing between the multiple sub-frames 50 between the support frame 5 is widened, allowing the retention device 9 to extend. When the support frame 5 is widened, the telescopic connector 6 is pulled, causing the second connecting arm 62 to be pulled out from the inside of the first connecting arm 61, and the third connecting arm 63 to be pulled out from the inside of the second connecting arm 62. Due to the movement of the support frame 5 and the change in the angle of the telescopic connector 6 at the first fixed seat 51, the first opening 611 at the first fixed seat 51 rotates at an angle, and at the same time, the angle of the second opening 631 at the second fixed seat 52 also changes. Because the triangle formed by the telescopic connector 6, the first fixed member 51 and the second fixed member 52 has stability, the telescopic connector 6 is used to stably connect the multiple sub-frames 50, allowing the retention device 9 to be stably extended. In addition, multiple sub-frames 50 are connected by telescopic connectors 6. Compared with the support frame 5 which is rigidly connected to multiple sub-frames 50, the support frame 5 connected by telescopic connectors 6 can adapt to the bumps and other effects caused by uneven terrain on the track 1 when moving, making it easier for the support frame 5 to move.

[0105] In one embodiment, the drug delivery component 7 includes a first connecting tube 80, the input end of which is disposed on one side of the sub-plate 4. The first connecting tube 80 extends to the top of the sub-frame 50 and extends into two ends of the top of the sub-frame 50 to form diversion tubes 81. A first spraying device 82 is disposed on the inner side of the top of the sub-frame 50, and the first spraying device 82 is connected to the diversion tubes 81.

[0106] In one embodiment, the drug delivery assembly 7 further includes a second connecting tube 70. Limiting members 55 are provided on the lower outer sides of the sub-frame 50, and the second connecting tube 70 is fixedly connected to the limiting members 55. Second spraying devices 71 are provided on both inner sides of the sub-frame 50, and the second spraying devices 71 communicate with the second connecting tube 70. In this embodiment, as... Figure 6 As shown, the input end of the first connecting pipe 80 is located on one side of the sub-plate 4. The input end of the first connecting pipe 80 is used to input nutrient solution and / or water. It can be located at the starting point on one side of the sub-plate 4 or at other positions on one side of the sub-plate 4. Similarly, the input end of the second connecting pipe 70 is located on one side of the sub-plate 4 and is used to input nutrient solution and / or water. It can be located at the starting point on one side of the sub-plate 4 or at other positions on one side of the sub-plate 4. The present invention is not limited thereto.

[0107] In an embodiment, the first spraying device 82 and the second spraying device 71 are arranged in an array. The first spraying device 82 and the second spraying device 71 can be water mist type, water droplet type, or the like, as required, and the present application is not limited in this regard.

[0108] In an embodiment, the track type plant phenotype platform has a general controller which can control the detection box 37, the traveling mechanism 2, and the connecting assembly 30 according to data reported by sensors such as position sensors and image sensors. The general controller can be located on one side of the extension plate 38 of the detection box 37, or can be arranged at other positions such as the function frame 3, and the present application is not limited in this regard.

[0109] As shown in Figure 9 the present application also provides a control method of a track type plant phenotype platform, which is applied to any one of the above plant phenotype platforms, and includes the following steps:

[0110] Step S1: driving the traveling mechanism 2 and the function frame 3 to travel on the track;

[0111] Step S2: driving the detection device 39 on the function frame 3 to detect the growth condition of the plant to be measured;

[0112] Step S3: controlling the connecting assembly 30 to be connected with the support frame 5, driving the traveling mechanism 2 and the function frame 3, and the support frame 5 and the retention device 9 to cover the plant to be measured;

[0113] Step S4: according to the detection result of the growth condition of the plant to be measured, configuring nutrient solution required by the plant to be measured, and providing the nutrient solution and water for the plant to be measured through the first connecting pipe 80 and the second connecting pipe 70.

[0114] It should be noted that, as required, step S3 can be performed first, and then steps S1, S2, and S4 are performed, so as to save the time for driving the function frame 3 to return to the starting point to be connected with the support frame, and the working efficiency is higher, that is, the execution order of steps S1 to S4 is not limited.

[0115] Compared with the prior art, the track type plant phenotype platform and the control method provided by the present application can drive the support frame to move on the track through the function frame, the retention device arranged on the inner side of the support frame can retain the sprayed nutrient solution and water on the plant, the retention device is convenient to move under the driving of the support frame, and the nutrient solution and water are well retained, which is helpful for the growth of the plant.
