Description

Technical Field

[0001] This invention relates to the field of agricultural monitoring technology, and in particular to an agricultural Internet of Things (IoT) environmental monitoring device. Background Technology

[0002] Smart agriculture is the smart economy within agriculture, and can also be seen as the specific manifestation of the smart economy in agriculture. For developing countries, smart agriculture is a major component of the smart economy and a primary means for them to eliminate poverty, realize late-mover advantage, achieve economic development and catch up with the world, and realize the strategy of catching up. In the field of smart agriculture, environmental monitoring based on the Internet of Things is an essential means. It can monitor various data of crop growth environment in real time through physical plant environment monitoring devices, thereby achieving the goal of scientific planting.

[0003] Existing agricultural IoT environmental monitoring devices often employ carbon dioxide sensors to measure the concentration of carbon dioxide in the air. Carbon dioxide is a primary reactant in photosynthesis, and its concentration directly affects the photosynthetic efficiency of crops, determining their growth, development, maturity, stress resistance, quality, and yield. By adjusting the supply of carbon dioxide gas, the normal carbon dioxide concentration required for photosynthesis in indoor plants can be ensured.

[0004] Currently, most environmental monitoring devices used in agricultural greenhouses can only monitor the gas state in a certain space within the greenhouse for a certain period of time. Due to the slow airflow in the relatively enclosed greenhouse, existing monitoring devices cannot monitor the air state of the entire greenhouse in real time. At the same time, since carbon dioxide detectors are fixed to their supports, it is difficult to monitor the air state of the greenhouse from various angles in real time. Therefore, targeted improvements are needed. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that existing technologies can only monitor the gas state in a certain space within a greenhouse for a certain period of time. Since the airflow in a relatively enclosed greenhouse is slow, existing monitoring devices cannot monitor the air state of the entire greenhouse in real time. At the same time, since the carbon dioxide detector is fixed to the bracket, it is difficult to monitor the air state of the greenhouse from various angles in real time. Therefore, this invention proposes an agricultural Internet of Things environmental monitoring device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An agricultural IoT environmental monitoring device includes a first support frame, and further includes: a first motor fixedly connected to the inner wall of the first support frame, a first rotating rod fixedly connected to the output end of the first motor, a first support plate fixedly connected to the outer wall of the first rotating rod, and a concave plate fixedly connected to the side wall of the first support plate; a second rotating rod rotatably connected to the bottom of the first support plate, a second gear fixedly connected to the outer wall of the second rotating rod, and a first gear fixedly connected to the surface of the first support frame, the first gear and the second gear meshing with each other; a first threaded rod rotatably connected to the inner wall of the concave plate, a chain drivingly connecting the first threaded rod and the second rotating rod, and a moving block threadedly connected to the outer wall of the first threaded rod; and a carbon dioxide detector fixedly connected to the moving block.

[0008] To further improve the sampling efficiency of outside air, a housing is fixedly connected to the surface of the concave plate, an air inlet pipe is fixedly connected to the housing, an impeller is fixedly connected to the outer wall of the first threaded rod, the impeller is located inside the housing, and a flexible hose is fixedly connected between the housing and the carbon dioxide detector.

[0009] To facilitate soil moisture detection, preferably, the system further includes: a second threaded rod fixedly connected to the bottom of the first rotating rod, the outer wall of which is threadedly connected to a second support frame; a third rotating rod fixedly connected to the inner wall of the second support frame, the outer wall of which is symmetrically fixedly connected to connecting blocks, the bottom of which is fixedly connected to a connecting rod, and the bottom of which is fixedly connected to a soil sampling hopper; and a first cylinder fixedly connected to the inner wall of the first support frame, the output end of which is fixedly connected to a soil conductivity sensor.

[0010] To further improve the drilling efficiency of the soil-taking bucket, the soil-taking bucket is further shaped into a cone.

[0011] To facilitate cleaning the soil in the soil hopper after the test, a second motor is fixedly connected to the surface of the second support frame. The output end of the second motor is fixedly connected to the third rotating rod, which is rotatably connected to the second support frame.

[0012] To further facilitate limiting the position of the second support frame, a limiting plate is fixedly connected to the bottom of the second threaded rod, and the outer diameter of the limiting plate is larger than the outer diameter of the second threaded rod.

[0013] To facilitate adjustment of the soil-collecting hopper's position, a second cylinder is fixedly connected to the inner wall of the first support frame, and a second support plate is fixedly connected to the output end of the second cylinder. The first motor is fixedly connected to the second support plate, and grooves are opened on the surfaces of the first support frame and the first gear, with the first rotating rod located in the groove.

[0014] To facilitate the adjustment of the position of the soil conductivity sensor, a third cylinder is fixedly connected to the inner wall of the first support frame, and an L-shaped plate is fixedly connected to the output end of the third cylinder. The first cylinder is fixedly connected to the surface of the L-shaped plate.

[0015] To facilitate cleaning of the soil conductivity sensor probe, the system further includes: a third support plate fixedly connected to the side wall of the L-shaped plate, the surface of which has a through hole larger than the outer diameter of the soil conductivity sensor probe; a cleaning ring rotatably connected to the bottom of the third support plate, the inner wall of which is fixedly connected to bristles; a third gear fixedly connected to the outer wall of the cleaning ring, the bottom of which is rotatably connected to a fourth gear that meshes with the third gear; and a fourth support plate fixedly connected to the inner wall of the first support frame, the surface of which is fixedly connected to a rack that meshes with the fourth gear.

[0016] Preferably, it further includes guide rods symmetrically fixedly connected to the inner wall of the concave plate, and the moving block is slidably connected to the guide rods.

[0017] Compared with the prior art, the present invention provides an agricultural Internet of Things (IoT) environmental monitoring device, which has the following beneficial effects:

[0018] 1. This agricultural IoT environmental monitoring device drives a concave plate to rotate by starting a first motor. On the one hand, the rotation of the concave plate accelerates the flow of surrounding air, making the detection results more accurate. On the other hand, the concave plate drives the carbon dioxide detector to rotate, which facilitates the adjustment of the carbon dioxide detector's angle and enables the detection of multiple measuring points at multiple angles. This facilitates the subsequent averaging of various detection results, thereby reducing detection errors and allowing staff to take corresponding measures based on the detection results, thus improving the quality of crops.

[0019] 2. This agricultural IoT environmental monitoring device utilizes the rotation of the second rotating rod during its revolution. The revolution of the second rotating rod facilitates the adjustment of the angle of the carbon dioxide detector, while the rotation of the second rotating rod facilitates the adjustment of the height of the carbon dioxide detector. This allows for convenient collection of air samples from different heights and angles, enabling comprehensive analysis of carbon dioxide content and further improving the accuracy of the detection results. At the same time, it also increases the sampling efficiency of the outside air.

[0020] 3. This agricultural IoT environmental monitoring device can detect the air around crops and the moisture of the soil, thereby improving the quality of crops. After the soil test is completed, the second motor is started to drive the soil hopper to flip, so that the soil in the soil hopper can be poured out for the next use. At the same time, the brush removes the soil from the probe surface of the soil conductivity sensor. Under the action of centrifugal force, the soil on the brush falls off, reducing the impact on the test results. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention 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. Therefore, they should not be construed as limitations on this invention.

[0030] Example 1:

[0031] Reference Figures 1-2 An agricultural IoT environmental monitoring device includes a first support frame 1 with movable wheels at the bottom, which facilitates moving the position of the first support frame 1 as needed. The agricultural IoT environmental monitoring device also includes: a first motor 101 fixedly connected to the inner wall of the first support frame 1, and a first rotating rod 102 fixedly connected to the output end of the first motor 101; a first support plate 103 fixedly connected to the outer wall of the first rotating rod 102, and a concave plate 104 fixedly connected to the side wall of the first support plate 103. When the first support plate 103 rotates, the concave plate 104 drives the surrounding airflow.

[0032] This agricultural IoT environmental monitoring device also includes: a second rotating rod 201 rotatably connected to the bottom of the first support plate 103, with a second gear 202 fixedly connected to the outer wall of the second rotating rod 201; a first gear 2 fixedly connected to the surface of the first support frame 1, with the first rotating rod 102 and the first gear 2 coaxial; to reduce wear between the first rotating rod 102 and the first gear 2, the first rotating rod 102 passes through the first gear 2, the inner diameter of the first gear 2 is larger than the outer diameter of the first rotating rod 102, and the first gear 2 and the second gear 202 mesh with each other; and a first threaded rod 204 rotatably connected to the inner wall of the concave plate 104, with a moving block 206 threadedly connected to the outer wall of the first threaded rod 204, the moving block 206 being in contact with the side wall of the concave plate 104.

[0033] Reference Figure 2 and Figure 4 The outer walls of the first threaded rod 204 and the second rotating rod 201 are both fixedly connected to sprockets, and the adjacent sprockets are connected by a chain 203 for transmission.

[0034] The carbon dioxide detector 105 is fixedly connected to the movable block 206. The carbon dioxide detector 105 can be the S20A2 from Xuzhou Farad Electronic Technology Co., Ltd., or it can be a similar detector that meets national standards on the market.

[0035] In use, the first motor 101 is started to drive the first rotating rod 102 to rotate. The first rotating rod 102 drives the first support plate 103 to rotate, and the first support plate 103 drives the concave plate 104 to rotate. On the one hand, the rotation of the concave plate 104 accelerates the flow of surrounding air, which can make the detection results more accurate. On the other hand, the concave plate 104 drives the carbon dioxide detector 105 to rotate, which makes it easy to adjust the angle of the carbon dioxide detector 105 and realize the detection of multiple measuring points at multiple angles. This facilitates the subsequent averaging of various detection results, thereby reducing detection errors and allowing staff to take corresponding measures based on the detection results, thereby improving the quality of crops.

[0036] The first support plate 103 drives the second rotating rod 201 to revolve around the first rotating rod 102. At the same time, since the first gear 2 and the second gear 202 mesh with each other, the first gear 2 drives the second gear 202 to rotate, the second gear 202 drives the second rotating rod 201 to rotate, the second rotating rod 201 drives the first threaded rod 204 to rotate, and the first threaded rod 204 drives the moving block 206 to slide on the outer wall of the guide rod 205, thereby facilitating the adjustment of the carbon dioxide detector 105, thus facilitating the collection of air at different heights, comprehensive analysis of carbon dioxide content, and further improving the accuracy of the detection results.

[0037] The first motor 101 can rotate in both directions. When the moving block 206 moves from one end of the first threaded rod 204 to the other end, the first motor 101 rotates in reverse.

[0038] When the moving block 206 moves from one end of the first threaded rod 204 to the other end, the first motor 101 rotates more than 1 revolution.

[0039] The carbon dioxide detector 105 also has an air inlet, allowing gas to enter and be detected. Figure 4 When the first threaded rod 204 drives the impeller 303 to rotate clockwise, the impeller 303 draws in air, increasing the air intake and improving the stability of the detection. When the first threaded rod 204 rotates counterclockwise, the carbon dioxide detector 105 can be detected through its own air intake port.

[0040] A guide rod 205 is symmetrically fixed to the inner wall of the concave plate 104. The guide rod 205 passes through the movable block 206, and the movable block 206 is slidably connected to the guide rod 205.

[0041] Reference Figures 4-5 A housing 3 is fixedly connected to the surface of the concave plate 104. An air inlet pipe 301 is fixedly connected to the housing 3. An impeller 303 is fixedly connected to the outer wall of the first threaded rod 204. The impeller 303 is located inside the housing 3. A hose 302 is fixedly connected between the housing 3 and the carbon dioxide detector 105. The first threaded rod 204 drives the impeller 303 to rotate. The impeller 303 drives the outside airflow into the housing 3, and then into the carbon dioxide detector 105 through the hose 302, which improves the sampling efficiency of the outside air.

[0042] Example 3:

[0043] Reference Figures 1-2 as well as Figures 5-6 The implementation is basically the same as in Example 2, but with the addition of a specific implementation plan for detecting soil moisture.

[0044] Since crop growth is also affected by soil moisture, therefore, referring to Figures 1-2 The agricultural IoT environmental monitoring device also includes: a second threaded rod 4 fixedly connected to the bottom of the first rotating rod 102, with a second support frame 401 threadedly connected to the outer wall of the second threaded rod 4; a third rotating rod 402 fixedly connected to the inner wall of the second support frame 401, with connecting blocks 403 symmetrically fixedly connected to the outer wall of the third rotating rod 402, with a connecting rod 404 fixedly connected to the bottom of the connecting block 403, with a soil-collecting hopper 405 fixedly connected to the bottom of the connecting rod 404, and a protruding strip fixedly connected to the outer wall of the soil-collecting hopper 405 for easy soil collection; and a first cylinder 406 fixedly connected to the inner wall of the first support frame 1, with a soil conductivity sensor 407 fixedly connected to the output end of the first cylinder 406.

[0045] It should be noted that the soil conductivity sensor 407 can be either ME-EC from Zhejiang Mindray Sensor Technology Co., Ltd., or a similar sensor that meets national standards and is available on the market.

[0046] Reference Figure 6 The inner wall of the first support frame 1 is fixedly connected to the third cylinder 502, the output end of the third cylinder 502 is fixedly connected to the L-shaped plate 503, and the first cylinder 406 is fixedly connected to the surface of the L-shaped plate 503.

[0047] Reference Figure 5 The inner wall of the first support frame 1 is fixedly connected to the second cylinder 5, and the output end of the second cylinder 5 is fixedly connected to the second support plate 501. In this embodiment, the first motor 101 fixedly connected to the inner wall of the first support frame 1 is converted into the first motor 101 being fixedly connected to the second support plate 501. The surfaces of the first support frame 1 and the first gear 2 are both provided with grooves 608, and the first rotating rod 102 is located in the grooves 608.

[0048] The groove 608 is a circular groove, and the diameter of the groove 608 is larger than the outer diameter of the first rotating rod 102.

[0049] In use, the second cylinder 5 is activated to drive the second support plate 501 to move. The second support plate 501 drives the first rotating rod 102 to move, and the first rotating rod 102 drives the second gear 202 to move, thereby separating the second gear 202 from the first gear 2. Then, the first motor 101 is activated to drive the second threaded rod 4 to rotate. The second threaded rod 4 drives the second support frame 401 to descend and rotate at the same time. On the one hand, this facilitates the circulation of surrounding airflow, and on the other hand, it facilitates the soil hopper 405 to drill into the soil, causing the soil to roll into the soil hopper 405. Then, by controlling the second cylinder 5 and the first motor 101, the soil hopper 405 is returned to its initial position. The third cylinder 502 is activated to drive the L-shaped plate 503 to move towards the soil hopper 405 until the soil conductivity sensor 407 is above the soil hopper 405. Then, the first cylinder 406 is activated to drive the soil conductivity sensor 407 to descend, so that the probe of the soil conductivity sensor 407 is inserted into the sampled soil to detect the soil moisture.

[0050] It should be noted that after the soil hopper 405 comes into contact with the soil, the second support frame 401 can also be manually rotated to apply an additional driving force, so that it can descend and rotate more stably, making it easier to transport the soil into the soil hopper 405 through the convex strip.

[0051] The bottom of the first support frame 1 is hollow. Since only a small distance is needed to separate the second gear 202 from the first gear 2, the soil hopper 405 is still directly above the bottom of the hollow first support frame 1 after the second cylinder 5 is started.

[0052] To improve the drilling efficiency of the 405 soil-boring bucket, refer to Figure 1 The soil bucket 405 is cone-shaped.

[0053] To facilitate limiting the position of the second support frame 401, a limiting plate 409 is fixedly connected to the bottom of the second threaded rod 4, and the outer diameter of the limiting plate 409 is larger than the outer diameter of the second threaded rod 4.

[0054] Example 4:

[0055] Reference Figure 1 , Figure 3 as well as Figure 6 The implementation is basically the same as in Example 3, but with the addition of a specific implementation scheme for the soil cleaning bucket 405 and the soil conductivity sensor 407.

[0056] Since the soil inside the soil sampling bucket 405 needs to be cleaned after the test to facilitate the next use, therefore, referring to... Figure 1 A second motor 408 is fixedly connected to the surface of the second support frame 401. In this embodiment, the third rotating rod 402, which is fixedly connected to the inner wall of the second support frame 401, is converted into a situation where the output end of the second motor 408 is fixedly connected to the third rotating rod 402, and the third rotating rod 402 is rotatably connected to the second support frame 401.

[0057] The second motor 408 is started to drive the third rotating rod 402 to rotate. The third rotating rod 402 drives the connecting block 403 to rotate. The connecting block 403 drives the connecting rod 404 to rotate. The connecting rod 404 drives the soil-collecting bucket 405 to flip, so as to facilitate the dumping of soil from the soil-collecting bucket 405.

[0058] During soil moisture detection, some soil tends to adhere to the probe of the soil conductivity sensor 407, potentially affecting future use. Therefore, referring to... Figure 3 and Figure 6The agricultural IoT environmental monitoring device also includes: a third support plate 6 fixedly connected to the side wall of the L-shaped plate 503, the surface of the third support plate 6 having a through hole 601, the diameter of the through hole 601 being larger than the outer diameter of the probe of the soil conductivity sensor 407; a cleaning ring 602 rotatably connected to the bottom of the third support plate 6, the inner wall of the cleaning ring 602 being fixedly connected to bristles 603; a third gear 604 fixedly connected to the outer wall of the cleaning ring 602, the bottom of the third support plate 6 being rotatably connected to a fourth gear 605, the fourth gear 605 meshing with the third gear 604; and a fourth support plate 607 fixedly connected to the inner wall of the first support frame 1, the surface of the fourth support plate 607 being fixedly connected to a rack 606, the rack 606 meshing with the fourth gear 605.

[0059] It should be added that, referring to Figure 3 and Figure 6 The number of cleaning rings 602 is the same as the number of probes of the soil conductivity sensor 407. Adjacent third gears 604 mesh with each other, and the fourth gear 605 meshes with one of the third gears 604. The inner diameter of the cleaning ring 602 is larger than the outer diameter of the probe of the soil conductivity sensor 407. The cleaning ring 602 is coaxial with the corresponding probe of the soil conductivity sensor 407.

[0060] After the soil testing is completed, the first cylinder 406 is controlled to raise the soil conductivity sensor 407. The soil conductivity sensor 407 drives the probe to rise, thereby moving the probe within the cleaning ring 602. The bristles 603 on the inner wall of the cleaning ring 602 sweep away the soil adhering to the probe surface. The third cylinder 502 is controlled to move the L-shaped plate 503, thereby moving the soil conductivity sensor 407 away from the soil collection hopper 405. Since the fourth gear 605 meshes with the rack 606, the fourth gear 605 rotates. The fourth gear 605 drives the third gear 604 to rotate, and the third gear 604 drives the cleaning ring 602 to rotate, thereby shaking off the soil adhering to the bristles 603.

[0061] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
