[0002] In agricultural production and management, monitoring the plant growth environment is a crucial link. Through real-time monitoring, we can timely understand the growth status of plants, environmental parameters, and possible diseases and pests, and provide a scientific decision-making basis for agricultural production. However, traditional plant growth monitoring systems often have obvious limitations when facing large-scale regional monitoring.

[0003] Chinese patent CN213938158U discloses a multifunctional monitoring device of agricultural Internet of Things, which relates to the technical field of agricultural Internet of Things and solves the technical problems that the existing monitoring devices cannot move over long distances, have a small monitoring range and poor monitoring effect.

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Reference Figures 1 to 10As shown: an agricultural Internet of Things monitoring device, including a housing 1, a transmission module 2 and a monitoring body 5; the housing 1 is respectively provided with an upper strip opening 11 and a lower strip opening 12 on the upper and lower surfaces; the transmission module 2 is arranged inside the housing 1, and the transmission module 2 includes a first movable plate 21 that can move along the upper strip opening 11 and a second movable plate 22 that can move along the lower strip opening 12, and the first movable plate 21 and the second movable plate 22 can move in opposite directions relative to the upper strip opening 11 and the lower strip opening 12; the first movable plate 21 and the second movable plate 22 are respectively provided with a first rotating plate 21 and a second rotating plate 22. The first rotating sleeve 3 and the second rotating sleeve 4, the two ends of the first rotating sleeve 3 and the second rotating sleeve 4 respectively extend to the outside of the casing 1 through the upper strip opening 11 and the lower strip opening 12; the first rotating sleeve 3 and the second rotating sleeve 4 are respectively sleeved with a first gear 41 on the outside, and a plurality of racks 14 that can mesh with the first gear 41 are provided on both sides of the interior of the casing 1 along the travel direction of the first movable plate 21 and the second movable plate 22, and the racks 14 on both sides of the casing 1 are staggered; the monitoring body 5 is provided with a pair and is respectively arranged at the bottom of the first rotating sleeve 3 and the second rotating sleeve 4.

[0033] The specific steps for using the device are as follows: First, the housing 1 is installed in the area to be monitored; Secondly, when it is necessary to monitor a large area, the transmission module 2 is started, and the first movable plate 21 and the second movable plate 22 are moved in opposite directions through the driving mechanism in the transmission module 2, thereby driving the corresponding first rotating sleeve 3 and the second rotating sleeve 4 to move. When the first rotating sleeve 3 and the second rotating sleeve 4 move in opposite directions, the first rotating sleeve 3 and the second rotating sleeve 4 pass through the staggered racks 14 in turn through their respective first gears 41, and through the mutual engagement of the first gears 41 and the racks 14, the first rotating sleeve 3 and the second rotating sleeve 4 rotate back and forth clockwise and counterclockwise during the movement, and the monitoring bodies 5 respectively connected to the bottom of the first rotating sleeve 3 and the second rotating sleeve 4 rotate respectively. In this way, the monitoring body 5 can continuously expand the monitoring range during the movement, effectively solving the blind spot problem in conventional monitoring.

[0034] In addition, a controller 6 is also provided inside the housing 1, and the transmission module 2 and the monitoring body 5 are both electrically connected to the controller 6. The image information captured by the monitoring body 5 is first transmitted to the controller 6, and the controller 6 then sends this information to the user in the form of a signal. In this way, the user can intuitively observe the growth of the plant in the background, realizing comprehensive and no-dead-angle monitoring of the plant growth environment of the agricultural Internet of Things.

[0035] Reference Figure 3 and Figure 4As shown: strip mounting plates 13 distributed along the travel direction of the first movable plate 21 and the second movable plate 22 are respectively arranged on both sides of the interior of the casing 1, and plug holes 131 distributed at equal intervals along its length direction are arranged on the strip mounting plate 13, and a pin 141 that can be plugged into the plug hole 131 is arranged on one side of the rack 14.

[0036] In order to meet the monitoring needs of users, racks 14 of different lengths can be customized. When racks 14 of different lengths cooperate with the first gear 41, different rotation ranges will be generated. The longer the rack 14 is, the larger the rotation range of the first gear 41 will be. In view of the uncertainty of plant planting areas, large-scale planting areas need to cover a larger monitoring range, while small-scale planting areas only require small-scale monitoring. Therefore, racks 14 of corresponding lengths can be installed according to specific planting areas to accurately control the rotation range. Specifically, a longer rack 14 is installed on the side of the strip mounting plate 13 close to the large-scale plant planting area; and a shorter rack 14 is installed on the side close to the small-scale planting area, thereby achieving effective monitoring of specific plant planting areas.

[0037] In addition, the installation process of the rack 14 is simple and quick. The rack 14 can be easily removed and installed by simply inserting the latches 141 on the rack 14 into the corresponding insertion holes 131 on the strip-shaped installation plate 13 .

[0038] Reference Figure 2 and Figure 5 As shown, a first slide rail 15 is provided on the housing 1 along the extending direction of the upper strip opening 11 and the lower strip opening 12 , and a first slider 16 is rotatably provided at the upper and lower ends of the first rotating sleeve 3 and the second rotating sleeve 4 to move along the corresponding first slide rail 15 .

[0039] When the two ends of the first rotating sleeve 3 and the second rotating sleeve 4 move along the upper strip opening 11 and the lower strip opening 12 respectively, the first slider 16 rotatably arranged at the two ends of the first rotating sleeve 3 and the second rotating sleeve 4 can move along the corresponding first slide rail 15, thereby enhancing the stability of the first rotating sleeve 3 and the second rotating sleeve 4 during the movement, and effectively avoiding the problem of reduced monitoring quality caused by the movement of the monitoring body 5.

[0040] Reference Figure 2 , Figure 3 and Figure 5As shown: the lower ends of the first rotating sleeve 3 and the second rotating sleeve 4 are respectively sleeved with second gears 31. When the first rotating sleeve 3 and the second rotating sleeve 4 are close to each other, the two second gears 31 are meshed with each other, and the first gears 41 on the first rotating sleeve 3 and the second rotating sleeve 4 are respectively in a separated state from the rack 14 in the housing 1. The first slider 16 on the first rotating sleeve 3 away from the second gear 31 is provided with a rotating drive mechanism 32 capable of driving the first rotating sleeve 3 to rotate.

[0041] In the initial state, the two monitoring bodies 5 are close to each other, the transmission module 2 is in a stopped working state, and the two monitoring bodies 5 are distributed in a mirror image. When it is necessary to monitor the plants in a small area, the controller 6 is electrically connected to the rotation drive mechanism 32, and the controller 6 starts the rotation drive mechanism 32, and drives the first rotating sleeve 3 to rotate through the rotation drive mechanism 32. When the first rotating sleeve 3 rotates, it drives the second gear 31 installed thereon to rotate. The second gear 31 on the first rotating sleeve 3 then engages with the second gear 31 on the second rotating sleeve 4, and drives the second rotating sleeve 4 to rotate, so that the monitoring bodies 5 respectively installed on the first rotating sleeve 3 and the second rotating sleeve 4 can realize reverse rotation, so that the plants in a small area can be fully monitored.

[0042] In summary, when monitoring plants in a small area, the two monitoring bodies 5 can increase the monitoring range of the plants in the small area by rotating in opposite directions without moving, thereby improving the comprehensive diversity and efficiency of monitoring.

[0043] In addition, when the two second gears 31 are meshed with each other, the first gears 41 respectively provided on the first rotating sleeve 3 and the second rotating sleeve 4 will be in a disengaged state from the corresponding rack 14. A temporary storage area is designed inside the housing 1 for temporarily placing the two first gears 41 to ensure that the two first gears 41 are not meshed with any rack 14 in the initial state.

[0044] It should be noted that when the first gear 41 on the first rotating sleeve 3 and the second rotating sleeve 4 needs to mesh with the rack 14 again, the rotating drive mechanism 32 will adjust the first gear 41 on the first rotating sleeve 3 and the second rotating sleeve 4 to a state of matching with the rack 14 so that the first gear 41 meshes with the rack 14.

[0045] Reference Figure 2 , Figure 5 and Fig. 9As shown: the rotation drive mechanism 32 includes a first rotation motor 321, an extension plate 322, a third gear 323 and a fourth gear 324; the third gear 323 is sleeved on one end of the first rotation sleeve 3 away from the second gear 31; the extension plate 322 is arranged on the first slider 16 of the first rotation sleeve 3 away from the second gear 31, and one side of the extension plate 322 extends to the side of the third gear 323; the first rotation motor 321 is arranged at the bottom of the extension plate 322; the fourth gear 324 is arranged beside the third gear 323, and the third gear 323 is meshed with the fourth gear 324, and the output shaft of the first rotation motor 321 is connected to the center transmission of the fourth gear 324.

[0046] The first rotating motor 321 is electrically connected to the controller 6 to receive control signals. When the first rotating sleeve 3 needs to be driven to rotate, the controller 6 sends a start command to the first rotating motor 321. After receiving the command, the first rotating motor 321 starts and drives the fourth gear 324 connected thereto to start rotating. Subsequently, the fourth gear 324 drives the third gear 323 to rotate through meshing, and the third gear 323 transmits the rotational motion to the first rotating sleeve 3, thereby realizing the rotation of the first rotating sleeve 3.

[0047] Reference Figures 6 to 8 As shown: a second slide rail 17 distributed along the moving direction of the first movable plate 21 and the second movable plate 22 is provided on one side of the inner part of the casing 1, an L-shaped plate 18 is provided on the outer rotating sleeve of the first rotating sleeve 3 and the second rotating sleeve 4, a second slider 181 capable of moving along the second slide rail 17 is provided on one side of the L-shaped plate 18, a main alignment plate 182 and a secondary alignment plate 183 are respectively provided on the adjacent sides of the two L-shaped plates 18, and when the first rotating sleeve 3 and the second rotating sleeve 4 are close to each other, the main alignment plate 182 and the secondary alignment plate 183 are plugged and matched.

[0048] When the first rotating sleeve 3 and the second rotating sleeve 4 are approaching each other, the primary alignment plate 182 and the secondary alignment plate 183 are plugged and matched to ensure that the distance between the first rotating sleeve 3 and the second rotating sleeve 4 is maintained within a preset value range, thereby ensuring that the second gears 31 respectively installed on the first rotating sleeve 3 and the second rotating sleeve 4 can be accurately meshed.

[0049] The two ends of the second slide rail 17 are respectively provided with a first photoelectric sensor 171, and the two L-shaped plates 18 are respectively provided with a touch plate 172 corresponding to each first photoelectric sensor 171. When the monitoring body 5 moves to the two end limit positions of the transmission module 2, the first photoelectric sensor 171 will come into contact with the touch plate 172 on the L-shaped plate 18. Once the contact occurs, the first photoelectric sensor 171 will immediately send a signal to the controller 6. After receiving the signal, the controller 6 will quickly send an instruction to the transmission module 2 to drive the first moving plate 21 and the second moving plate 22 inside it to move in the opposite direction, thereby driving the two monitoring bodies 5 to approach each other, and adjusting or resetting the monitoring range.

[0050] Reference Figure 7 and Figure 8 As shown: an arc 1821 protruding toward the secondary alignment plate 183 is formed on one side of the primary alignment plate 182 close to the secondary alignment plate 183, and an arc groove 1831 matching the arc 1821 is formed on one side of the secondary alignment plate 183 close to the primary alignment plate 182. When the first rotating sleeve 3 and the second rotating sleeve 4 approach each other, the arc 1821 fits tightly in the arc groove 1831. A second photoelectric sensor 1822 is inlaid on the primary alignment plate 182, and a working end of the second photoelectric sensor 1822 passes through one side of the primary alignment plate 182 and faces the inner center of the arc groove 1831.

[0051] A curvature 1821 protruding toward the secondary alignment plate 183 is provided on one side of the primary alignment plate 182 close to the secondary alignment plate 183, and a curved groove 1831 completely matching the curvature 1821 is correspondingly provided on the secondary alignment plate 183. When the first rotating sleeve 3 and the second rotating sleeve 4 approach each other and reach a predetermined position, the curvature 1821 on the primary alignment plate 182 will fit tightly into the curved groove 1831 on the secondary alignment plate 183, thereby ensuring precise positioning between the two.

[0052] In addition, the main alignment plate 182 is also inlaid with a second photoelectric sensor 1822, which is preferably a touch sensor. The working end of the second photoelectric sensor 1822 passes through one side of the main alignment plate 182, and the working end of the second photoelectric sensor 1822 accurately points to the inner center of the arc groove 1831. When the main alignment plate 182 and the secondary alignment plate 183 are not properly aligned, it means that the two second gears 31 are not properly engaged at the same time, and the working end of the second photoelectric sensor 1822 will not be able to contact the inner center of the arc groove 1831. At this time, the controller 6 does not receive the signal of the second photoelectric sensor 1822, and the first rotary motor 321 will not be able to start, so as to prevent the two second gears 31 from working in an abnormal state. On the contrary, when the two second gears 31 are fully engaged, the working end of the second photoelectric sensor 1822 will contact the inner center of the arc groove 1831, and the controller 6 will drive the first rotary motor 321 to work normally only after receiving the signal.

[0053] Reference Fig. 9 As shown: the first rotating sleeve 3 and the second rotating sleeve 4 are both provided with an electric threaded telescopic rod 7, the movable end of the electric threaded telescopic rod 7 is provided with a mounting plate 71, and the monitoring body 5 is detachably arranged on the mounting plate 71 by screws.

[0054] The electric threaded telescopic rod 7 is electrically connected to the controller 6. In view of the differences in plant heights, the height of the monitoring body 5 needs to be adjusted in a timely manner to ensure effective monitoring of plants at different heights. When the height of the monitoring body 5 needs to be adjusted, the controller 6 will start the electric threaded telescopic rod 7, and through the telescopic movement of the electric threaded telescopic rod 7, the mounting plate 71 and the monitoring body 5 mounted thereon are driven to rise and fall, thereby achieving precise adjustment of the height of the monitoring body 5.

[0055] Reference Fig. 9 and Fig.10 As shown: the inner circles of the first rotating sleeve 3 and the second rotating sleeve 4 are respectively slidably provided with limit sleeves 72, the bottom of the limit sleeve 72 is connected to the movable end of the electric threaded telescopic rod 7, the outside of the limit sleeve 72 is provided with a limit block 721 along its length direction, and the insides of the first rotating sleeve 3 and the second rotating sleeve 4 are both provided with a strip limit groove 722 for the limit block 721 to move vertically.

[0056] When the electric threaded telescopic rod 7 drives the monitoring body 5 to rise and fall, it also drives the limiting sleeve 72 to move along the axis of the corresponding first rotating sleeve 3 and the second rotating sleeve 4, and slides along the corresponding strip limiting grooves 722 on the first rotating sleeve 3 and the second rotating sleeve 4 through the limiting block 721 provided on the limiting sleeve 72, so that the mounting plate 71 and the monitoring body 5 are more stable when rising and falling.

[0057] Reference Figure 3 and Figure 5 As shown: the transmission module 2 also includes a second rotating motor 23 and two belt transmission mechanisms 24; the two belt transmission mechanisms 24 are respectively arranged on both sides of the casing 1, and a space for the first rotating sleeve 3 and the second rotating sleeve 4 to move is provided between the two belt transmission mechanisms 24, and the belt transmission mechanism 24 includes two transmission wheels 241, and the two transmission wheels 241 are rotatably arranged at the two ends inside the casing 1, and the two transmission wheels 241 are connected by a transmission belt 242, and the two sides of the first movable plate 21 and the second movable plate 22 are respectively connected to the transmission belts 242 in the two belt transmission mechanisms 24; a synchronous shaft 25 is provided between the two belt transmission mechanisms 24, and the two ends of the synchronous shaft 25 are respectively connected to the transmission wheels 241 in the two adjacent belt transmission mechanisms 24; the second rotating motor 23 is arranged outside the casing 1, and the output shaft of the second rotating motor 23 is connected to one end of the synchronous shaft 25.

[0058] The controller 6 is electrically connected to the second rotating motor 23. When the first moving plate 21 and the second moving plate 22 need to be driven to move in the opposite direction, the controller 6 will start the second rotating motor 23. Subsequently, the second rotating motor 23 drives the synchronous shaft 25 to rotate. The synchronous shaft 25 further drives the transmission wheels 241 in the two belt transmission mechanisms 24 to rotate, thereby driving the movement of the transmission belt 242. Specifically, the transmission belt 242 at the uppermost position drives the first moving plate 21 to move in one direction, while the transmission belt 242 at the lowermost position drives the second moving plate 22 to move in the opposite direction. In this way, the reverse movement effect of the two monitoring bodies 5 is achieved.

[0059] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
