Description

Technical Field

[0001] This invention relates to the field of crop monitoring technology, and in particular to a mobile automatic monitoring device for crop canopy microclimate. Background Technology

[0002] Crop canopy structure is an important factor affecting the photosynthetic characteristics of the crop canopy and microclimate factors. Different canopy structures can affect the microclimate environment such as light, temperature, humidity, and CO2 concentration within the crop canopy. Conversely, the canopy microenvironment is also an important factor affecting crop growth and development, dry matter formation and distribution, and yield formation.

[0003] Currently, the main methods for measuring the microenvironment within crop canopies, both domestically and internationally, are still traditional manual measurements. These include using handheld thermometers, CO2 meters, or handheld weather stations to measure air temperature, humidity, and CO2 concentration at different heights within the canopy at fixed times and locations. These methods require significant manual labor and cannot guarantee data reliability. Alternatively, fixed-point monitoring equipment can be used, but this equipment is limited to fixed locations and angles, making it difficult to track crop growth changes in real time.

[0004] Therefore, it is necessary to provide a new technical solution to solve the above-mentioned technical problems. Summary of the Invention

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0033] In order to obtain accurate and reliable research data, this invention provides a device for continuous and accurate monitoring of the microenvironment of crop populations. It can provide a more comprehensive evaluation of the internal environment of crop populations, such as temperature, humidity, wind speed, and carbon dioxide concentration, and is of great significance for optimizing variety plant type and population structure and for efficient resource utilization.

[0034] The following is combined Figures 1-4 This invention describes a mobile automatic crop canopy microclimate monitoring device.

[0035] Please refer to Figure 1The mobile crop canopy microclimate automatic monitoring device of the present invention includes: a base 1, a moving component 2, a rotating component 3, a telescopic component 4, an adjusting component 5, and a monitoring unit (not shown). The moving component 2 is mounted on the lower end surface of the base 1 and can move the base 1 forward, backward, left, and right. The rotating component 3 is mounted on the upper end surface of the base 1 and is arranged axially perpendicular to the base 1, allowing it to rotate circumferentially. The telescopic component 4 is mounted on the upper end surface of the rotating component 3 and can rotate synchronously with it. The telescopic component 4 is arranged perpendicular to the base 1 and can extend and retract in a direction perpendicular to the base 1. The monitoring unit is mounted on the telescopic component 4 and is used to monitor the crop canopy for continuous and accurate monitoring of the crop community microenvironment. It includes, but is not limited to, at least one of a temperature sensor, humidity sensor, CO2 concentration sensor, and camera.

[0036] The adjustment assembly 5 is mounted on the upper surface of the base 1 and includes a first driving member 51, a support rod 52, and a connecting frame 53. The first driving member 51 is mounted at the center of the base 1 and provides driving force. The support rod 52 is perpendicular to the base 1 and located around the first driving member 51, serving to support and fix the connecting frame 53. The telescopic assembly 4 and the rotating assembly 3 are both located around the support rod 52. The connecting frame 53 is mounted parallel to the base 1 on the first driving member 51, the support rod 52, and the telescopic assembly 4. The connecting frame 53 is slidably connected to the first driving member 51 and the support rod 52, and rotatably connected to the telescopic assembly 4. Since the telescopic assembly 4 is connected to the first driving member 51 through the connecting frame 53, the driving force of the first driving member 51 can be transmitted to the telescopic assembly 4 through the connecting frame 53, thereby driving the telescopic assembly 4 to perform telescopic movement.

[0037] The mobile crop canopy microclimate automatic monitoring device of the present invention uses a moving component 2 to drive the base 1 to move, facilitating the adjustment of the position of the automatic monitoring device and improving the flexibility of its use; and a rotating component 3 to drive the telescopic component 4 to rotate, thereby adjusting the rotation angle of the monitoring unit installed on the telescopic component 4; and an adjusting component 5 to adjust the telescopic length of the telescopic component 4 to change the height of the monitoring unit. Through the cooperation of the moving component 2, rotating component 3, telescopic component 4 and adjusting component 5, the mobile crop canopy microclimate automatic monitoring device can achieve real-time tracking of crop growth changes, improve the reliability of monitoring data and reduce labor costs, and can also perform segmented monitoring of the same plant at different heights.

[0038] Furthermore, the mobile crop canopy microclimate automatic monitoring device of the present invention also includes a control unit 6. The control unit 6 can be installed inside the base 1 and electrically connected to the moving component 2, the rotating component 3 and the adjusting component 5. The control unit 6 includes, but is not limited to, a battery, Bluetooth for communication control and a wireless module, thereby realizing remote control of the mobile crop canopy microclimate automatic monitoring device.

[0039] Please refer to Figure 1 and Figure 2 The mobile component 2 includes a load-bearing wheel 21, a track 22, and a third drive component 23. The load-bearing wheel 21 is rotatably connected to the base 1 and located on opposite sides of the base 1. The third drive component 23 is mounted on the lower end surface of the base 1 and is driven by the load-bearing wheel 21, providing driving force to the load-bearing wheel 21. The load-bearing wheel 21 located on the same side of the base 1 is driven by a track 22. The track 22 improves the adaptability of the mobile crop canopy microclimate automatic monitoring device to terrain.

[0040] Specifically, in this embodiment, the moving component 2 includes four road wheels 21, two tracks 22, and one third drive component 23. Two road wheels 21 are arranged on each of the left and right sides of the base 1, and the two road wheels 21 located on the same side of the base 1 are connected by a track for transmission. Of course, in other embodiments of the present invention, the tracks 22 may not be provided, and the number of road wheels 21 is not limited to four.

[0041] Please refer to Figure 2 and Figure 3 The mobile crop canopy microclimate automatic monitoring device of the present invention includes multiple rotating components 3, which are distributed around the base 1. Specifically, in this embodiment, four rotating components 3 are provided. Each rotating component 3 includes a rotating shaft 31, a rotating housing 33, and a second driving member 34. The rotating shaft 31 is fixedly connected to the upper end surface of the base 1, and a rotating plate 32 integrally formed with the rotating shaft 31 is provided at the end of the rotating shaft 31 away from the base 1. The diameter of the rotating plate 32 is larger than the diameter of the rotating shaft 31. The rotating shaft 31 has a cavity inside, and the second driving member 34 is fixedly installed in the cavity of the rotating shaft 31. The second driving member 34 is a motor, which can provide driving force for the rotation of the rotating components 3. The inner diameter of the rotating housing 33 is larger than the outer diameter of the rotating plate 32, and the rotating housing 33 is sleeved around the rotating shaft 31 and the rotating plate 32. The upper end surface of the rotating housing 33 is fixedly connected to the lower end surface of the telescopic component 4. The rotating plate 32 has an opening 321, through which the output shaft of the second driving member 34 passes and is movably inserted into the upper end face of the rotating housing 33.

[0042] For further details, please refer to Figure 3The output shaft of the second drive member 34 has a spline pin 341 at its end, which can be movably inserted into the upper surface of the rotating housing 33. After the spline pin 341 is inserted into the rotating housing 33, it can electrically drive the rotating housing 33 to rotate. The second drive member 34 has a self-locking capability. In addition, after the spline pin 341 is inserted into the rotating housing 33, there is a certain gap between the rotating plate 32 and the rotating housing 33, thereby reducing friction.

[0043] Furthermore, each rotating assembly 3 also includes two insert rods 35. Two locking holes 331 are oppositely arranged on the side wall of the rotating housing 33. One end of the insert rod 35 passes through the locking hole 331 and slides against the lower end face of the rotating plate 32. The other end of the insert rod 35 is fixedly connected to the rotating housing 33 by a fastener (such as a bolt). The insert rods 35 provide support for the rotation of the rotating housing 33 and prevent the rotating housing 33 from falling off the rotating shaft 31.

[0044] Furthermore, each rotating component 3 also includes multiple first rollers 36 and multiple second rollers 37. The insertion rod 35 and the rotating plate 32 slide against each other through multiple first rollers 36. The lower end face of the rotating housing 33 is rotatably connected to the upper end face of the base 1 through multiple second rollers 37, which can reduce the friction generated by rotation.

[0045] Please continue to refer to Figure 1 and Figure 2 The mobile crop canopy microclimate automatic monitoring device of the present invention includes multiple telescopic components 4, which are distributed around the base 1 in a one-to-one correspondence with multiple rotating components 3. Specifically, in this embodiment, four telescopic components 4 are provided, each of which includes multiple telescopic rods 41, multiple rotating slots 42, and multiple mounting plates 43. Each telescopic rod 41 has a rotating slot 42 fixedly connected to its end face away from the base 1, adjacent telescopic rods 41 are fixedly connected through the rotating slots 42, and a mounting plate 43 is fixedly installed on the outer end face of each rotating slot 42. The monitoring unit is mounted on the mounting plate 43.

[0046] The multi-stage telescopic rods 41 are connected sequentially along the direction perpendicular to the base 1, and each stage of the telescopic rod 41 can extend and retract along the direction perpendicular to the base 1. The extension and retraction length range of each stage of the telescopic rod 41 can be equal or unequal depending on the actual situation. The rotating groove 42 is an annular groove with a diameter larger than the diameter of the telescopic rod 41, and the connecting frame 53 is rotatably connected to the rotating groove 42. The mounting plate 43 between two adjacent telescopic rods 41 can also be an annular structure, and each mounting plate 43 has a notch at the corresponding position where it connects to the connecting frame 53 to facilitate the connection between the connecting frame 53 and the rotating groove 42.

[0047] Please continue to refer to Figure 1The adjusting assembly 5 includes four support rods 52 located around the first driving member 51, all four support rods 52 being fixedly connected to the upper end face of the base 1. The first driving member 51 of the adjusting assembly 5 includes a first motor 511 and a lead screw 512. The first motor 511 is fixedly mounted at the center of the upper end face of the base 1, and the lead screw 512 is perpendicular to the base 1 and is drively connected to the output shaft of the first motor 511. A connecting bracket 53 is mounted on the lead screw 512. The height of the lead screw 512 is greater than or equal to the maximum extension length of the telescopic assembly 4. The first driving member 51 may have a self-locking capability.

[0048] Please refer to Figure 4 Each connecting frame 53 includes a connecting frame body 531 and two sliding rods 532 located at least on one side of the connecting frame body 531 and slidably connected to the connecting frame body 531. The connecting frame body 531 is provided with a first through hole 5311 for the lead screw 512 to pass through, a second through hole 5312 for the support rod 52 to pass through, and a rotating ring 5313 connected to the telescopic assembly 4. The connecting frame 53 is slidably connected to the lead screw 512 through the first through hole 5311, and slidably connected to the support rod 52 through the second through hole 5312, and rotatably connected to the rotating groove 42 of the telescopic assembly 4 through the rotating ring 5313. The rotating ring 5313 is semi-circular in shape to match the rotating groove 42, so as to facilitate the insertion of the connecting frame 53 into the rotating groove 42, but is not limited to this.

[0049] The connecting frame body 531 has sliding grooves 5314 on opposite sides of the side with sliding rods 532. Two sliding rods 532 on the same side of the connecting frame body 531 are arranged opposite each other, and the two ends of each sliding rod 532 are slidably connected to the sliding grooves 5314 on both sides. Each sliding rod 532 has a contact block 5321 and two abutment blocks 5322. The contact block 5321 is located on the side of the sliding rod 532 near the lead screw 512 and is used to cooperate with the lead screw 512. The two abutment blocks 5322 are located on the side of the sliding rod 532 near the support rod 52. The two abutment blocks 5322 are located at the two ends of the sliding rod 532 and correspond to the second through hole 5312. The abutment blocks 5322 are used to movably abut against the support rod 52. The two sliding rods 532 on the same side of the connecting frame body 531 slide towards or away from each other. During this process, when the contact block 5321 is in contact with the lead screw 512, the abutment block 5322 is in a separated state from the support rod 52; when the contact block 5321 is in a separated state from the lead screw 512, the abutment block 5322 is in an abutment state from the support rod 52.

[0050] Furthermore, the inner end face of the contact block 5321 is rotatably connected to multiple sets of balls that cooperate with the lead screw 512, so that when the contact block 5321 abuts against the lead screw 512, rotating the lead screw 512 can drive the connecting frame 53 to move up and down along the support rod 52. After adjusting the height of the connecting frame 53 by the lead screw 512, the sliding rod 532 quickly slides to one side of the support rod 52, so that the abutting block 5322 abuts against the support rod 52, thus fixing the connecting frame 53 at the corresponding sliding height.

[0051] Furthermore, racks 533 are provided on opposite end faces of the two sliding rods 532 located on the same side of the connecting frame body 531. The racks 533 on the two sliding rods 532 are arranged opposite each other and mesh with each other through gears 534. One or two racks 533 can be provided on one sliding rod 532. The two opposing sliding rods 532 are connected by a transmission through racks 533 and gears 534.

[0052] Furthermore, each connecting frame 53 also includes an elastic element 535 and a telescopic element 536. Two sliding rods 532 located on the same side of the connecting frame body 531 are also elastically connected via the elastic element 535. The telescopic element 536 is disposed on the same side as the sliding rods 532, and is fixed to the connecting frame body 531 in a direction perpendicular to the sliding rods 532. The output section of the telescopic element 536 is connected to one of the sliding rods 532. The telescopic element 536 can be an electrically operated telescopic rod used to drive the sliding rods 532 to move. Since the two opposing sliding rods 532 are connected by a rack and pinion 533 and a gear 534, the telescopic element 536 can drive the two sliding rods 532 to slide synchronously. In addition, the elastic element 535 allows the abutment block 5322 to abut against the support rod 52 in its natural state; that is, the elastic element 535 is compressed when the two sliding rods 532 slide towards each other, and released when the two sliding rods 532 slide away from each other. Anti-slip textures can also be provided on the outer end face of the support rod 52.

[0053] In this embodiment, in order to more effectively fix the connecting frame 53, sliding rods 532, racks 533, gears 534, elastic elements 535 and telescopic elements 536 are provided on both the upper and lower sides of the connecting frame body 531, and the sliding rods 532 on the upper and lower sides of the connecting frame body 531 slide synchronously.

[0054] Please continue to refer to Figure 1 In this embodiment, each primary telescopic rod 41 is connected to a corresponding connecting frame 53, and the rotating ring 5313 of each connecting frame 53 is rotatably connected to the rotating groove 42 on the corresponding telescopic rod 41. In this way, the driving force of the first driving member 51 can be transmitted to each stage of the telescopic rod 41 through the connecting frame 53.

[0055] The rotating assembly 3, telescopic assembly 4, and adjusting assembly 5 of the mobile crop canopy microclimate automatic monitoring device of the present invention can all be detachably installed to facilitate the replacement and maintenance of later parts. The installation method for the rotating assembly 3 and telescopic assembly 4 includes: first, fixing the rotating outer shell 33 to the lower end face of the telescopic assembly 4; then, rotatingly fitting the rotating outer shell 33 onto the periphery of the rotating shaft 31 and rotating plate 32 assembly; then inserting and fixing the insertion rod 35, allowing the insertion rod 35 to slide against the lower end face of the rotating plate 32 to complete the installation of the rotating assembly 3 and telescopic assembly 4. The installation method for the adjusting assembly 5 includes: fitting the connecting frame 53 onto the lead screw 512 and support rod 52, and rotating the rotating ring 5313 on the connecting frame 53 to the rotating groove 42 to complete the installation of the adjusting assembly 5. Finally, installing the monitoring unit used on the mounting plate 43 completes the installation of the main body of the mobile crop canopy microclimate automatic monitoring device.

[0056] The working principle of the mobile crop canopy microclimate automatic monitoring device of the present invention is as follows: The third driving component 23 is activated, causing the moving component 2 to drive the mobile crop canopy microclimate automatic monitoring device to move forward, backward, left, and right. When it is necessary to adjust the angle of the monitoring unit on the mounting plate 43, the second driving component 34 at the location of the monitoring unit to be adjusted is activated, causing the corresponding telescopic component 4 to rotate synchronously with the rotating component 3, thereby controlling the rotation angle of the mounting plate 43, and thus controlling the monitoring angle of the monitoring unit to be adjusted. When the height of the monitoring unit needs to be adjusted, the first drive component 51 is activated, and the telescopic component 536 on the connecting frame 53 where the monitoring unit to be adjusted is located is activated. This causes the contact block 5321 on the connecting frame 53 to abut against the lead screw 512, thereby driving the connecting frame 53 to move longitudinally. At the same time, the connecting frame 53 also drives the telescopic rod 41 connected to it to extend and retract. When it moves to the required position, the telescopic component 536 is controlled to return to its original position. At this time, the elastic component 535 is released, pushing the two sliding rods 532 to slide in opposite directions, so that the abutment block 5322 abuts against the support rod 52, thereby fixing the connecting frame 53 at the corresponding sliding height, thus completing the height adjustment of the monitoring unit to be adjusted.

[0057] It should be noted that each connecting frame 53 can be controlled independently. Therefore, when adjusting the height of one connecting frame 53, since the other connecting frames 53 are all in contact with the support rod 52, the height of the monitoring unit corresponding to the other connecting frames 53 will not be affected.

[0058] The mobile crop canopy microclimate automatic monitoring device of the present invention, through the cooperation of moving components, rotating components, telescopic components and adjusting components, can realize real-time tracking of crop growth changes, improve the reliability of monitoring data and reduce labor costs. At the same time, it can also perform segmented monitoring of the same plant at different heights, and the obtained experimental data has high accuracy and reliability.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
