Description

Technical Field

[0001] The present invention relates to the field of greenhouse monitoring devices, and particularly to an intelligent greenhouse monitoring device controlled by a computer. Background Art

[0002] An intelligent greenhouse refers to applying an intelligent control system to greenhouse cultivation to create the most suitable environmental conditions for the growth of crops in the greenhouse. Monitoring devices are used to collect various environmental indicators of the greenhouse such as temperature, humidity, carbon dioxide, and light intensity, and data analysis is carried out by a computer. Facilities such as water curtains, fans, and sunshades in the greenhouse are controlled by the computer, thereby changing the biological growth environment inside the greenhouse.

[0003] A Chinese patent with the related publication number CN117629308A discloses a monitoring device for an intelligent greenhouse, which is fixedly installed on a greenhouse frame and includes an inspection structure, a lifting structure, a control structure, and a support crossbeam. By using the gravity of the monitoring instrument and the pulley itself, it moves back and forth inside the slide rail to achieve zero-drive dynamic monitoring during the monitoring process; and the lifting structure can be used to adjust the monitoring height within a range, and at the same time, the length of the slide rail can be designed according to the requirements of the monitoring area.

[0004] In view of the above related technologies, in the prior art, a monitoring device capable of moving vertically and adjusting its height is provided at the middle position of the greenhouse. The monitoring range of the monitoring device is the central area along the length direction of the greenhouse, and it is not easy to monitor the environmental indicators at the edges of the intelligent greenhouse and in the soil.

[0005] A Chinese patent with the related publication number CN113597944A discloses an intelligent agricultural greenhouse environment monitoring device, which is installed on a greenhouse frame and includes a slide rail, a slider, a connecting frame, a lifting structure, a fixing ring, and a monitoring instrument. The third gear rotates to drive the rotating ring to rotate circumferentially through the action of the annular teeth, so that the monitoring instrument can perform multi-directional monitoring.

[0006] In view of the above related technologies, in the prior art, a monitoring device capable of moving on a track is provided with the crossbeam of the intelligent greenhouse as the track. The monitoring range of this monitoring device is the area near the crossbeam of the intelligent greenhouse. It is not easy to monitor the position near the crops in the central area of the intelligent greenhouse, which is likely to result in incomplete monitoring data. Moreover, it is also impossible to monitor the soil indicators in the greenhouse, and the cost of slidingly connecting the monitoring devices in the prior art to each crossbeam of the greenhouse is relatively high.

[0007] In summary, the environmental indicators that can be monitored by the existing intelligent greenhouse monitoring devices controlled by a computer are limited, and the obtained monitoring data is incomplete. Summary of the Invention

[0008] Based on this, the object of the present invention is to provide an intelligent greenhouse monitoring device controlled by a computer, so as to solve the technical problem that the environmental indicators that can be monitored by the existing intelligent greenhouse monitoring device controlled by a computer are limited.

[0009] To achieve the above object, the present invention provides the following technical solution: An intelligent greenhouse monitoring device controlled by a computer, including a first slide rail, the first slide rail is connected below the cross beam of the intelligent greenhouse, a guide rail is arranged in the middle of the top of the cross beam along the length direction of the intelligent greenhouse, a moving platform is slidably arranged in the guide rail, a second slide rail is connected below the moving platform, the first slide rail and the second slide rail can communicate with each other, and further includes a moving beam, the moving beam can move along the first slide rail and the second slide rail, both ends of the moving beam are connected with wire reelers, and further includes a monitoring pod for monitoring environmental indicators in the intelligent greenhouse, the top of the monitoring pod is connected with the wire reeler through a connecting component.

[0010] By adopting the above technical solution, the moving beam can move along the greenhouse cross beam and can be transferred between the cross beams of the greenhouse. The wire reelers at both ends of the moving beam control the position of the monitoring pod by winding and unwinding the wire rope, and can place the monitoring pod on the ground at the required position in the intelligent greenhouse for monitoring soil indicators, expanding the monitoring range of air and soil in the intelligent greenhouse.

[0012] By adopting the above technical solution, the positioning of the moving plate is realized by the friction force generated by the static driving wheels and auxiliary wheels in close contact with the first slide rail on the cross beam, and the transfer of the position of the moving beam can be completed by the operation of the driving motor.

[0013] The present invention is further configured such that fixed boxes are connected to both ends of the moving beam, a rotating platform is rotatably connected to the fixed boxes, and wire reelers are installed on the rotating platform.

[0014] By adopting the above technical solution, the direction of the wire rope tension is kept stable as much as possible during the movement of the moving beam.

[0015] The present invention is further configured such that a draw wire is wound inside the wire reel, and the end portions of the draw wires wound by the two wire reels are respectively connected to both ends of the top of the mounting box. A monitoring pod is connected below the mounting box. The environmental index monitoring device provided in the monitoring pod includes an air temperature sensor and an air humidity sensor. A vertically downward soil monitor is further installed at the bottom end of the monitoring pod, and a photosensor is installed on the top surface of the mounting box.

[0016] By adopting the above technical solution, the position of the monitoring pod is controlled by the movement of the moving beam and the winding and unwinding of the wire reel, so as to monitor the air indexes at various positions in the intelligent greenhouse. At the same time, the monitoring pod can also be lowered to the bottom surface of the intelligent greenhouse, and the probe of the soil monitor is inserted into the soil to further monitor the soil indexes in the intelligent greenhouse.

[0017] The present invention is further configured such that hanging rings are rotatably connected to both ends of the top of the mounting box, and the end portions of the draw wires of the wire reel are connected to the hanging rings. Universal ball seats corresponding to each other are fixedly connected between the bottom surface of the mounting box and the top surface of the monitoring pod, and the two universal ball seats are connected by a connecting rod.

[0019] The present invention is further configured such that a telescopic box is slidably connected to the monitoring pod. A bottom plate is fixedly connected to the bottom end of the telescopic box. A plurality of through holes for the probes of the soil monitor to pass through are arranged at intervals on the bottom plate, and a cleaning assembly for cleaning the soil adhered to the probes of the soil monitor is arranged in the through holes.

[0020] By adopting the above technical solution, the cleaning assembly on the bottom plate automatically completes the cleaning of the probes every time the probes of the soil monitor are pulled out of the soil.

[0021] The present invention is further configured such that supporting feet extending downward are fixedly connected to both ends of the bottom of the telescopic box. The bottom ends of the supporting feet are lower than the bottom surface of the bottom plate. The inner wall of the telescopic box is in contact with the outer wall of the monitoring pod, and a sealing rubber ring in contact with the inner wall of the telescopic box is fixedly connected to the bottom end of the monitoring pod.

[0022] By adopting the above technical solution, the supporting feet keep the bottom plate away from the soil surface, and the gas blown out from the through holes can better blow out the impurities in the area where the probes are about to be inserted.

[0023] The present invention is further configured such that a light-transmitting plate is fixedly connected to the side wall of the telescopic box.

[0024] By adopting the above technical solution, the light-transmitting plate is conducive to observing the inside of the telescopic box. At the same time, when the telescopic box is not in contact with the ground, the light can be used to increase the temperature inside the telescopic box, so that the moisture on the surface of the probe of the soil monitor quickly evaporates, avoiding affecting the collection of soil environment data next time.

[0025] The present invention is further configured such that an inverted conical annular scraping blade is provided in the perforation, and the diameter of the bottom opening of the annular scraping blade is smaller than the diameter of the probe of the soil monitor.

[0026] By adopting the above technical solution, the annular scraping blade can closely adhere to the outer wall of the probe during the process of the probe of the soil monitor being retracted into the telescopic box, and scrape off impurities such as soil adhered to the outer wall of the probe.

[0027] The present invention is further configured such that a guiding groove is provided on the side wall of the monitoring pod, and a guiding block for sliding in the guiding groove is fixedly connected to the top end of the telescopic box. When the guiding block slides to the bottom end in the guiding groove, the probe of the soil monitor does not extend into the perforation.

[0028] By adopting the above technical solution, the cooperation of the guiding groove and the guiding block enables the telescopic box to slide vertically relative to the monitoring pod stably. At the same time, the guiding block plays a role in limiting the telescopic box, avoiding the situation that the telescopic box and the monitoring pod are separated from each other after the monitoring pod is lifted.

[0029] In summary, the present invention mainly has the following beneficial effects:

[0030] 1. The present invention suspends a monitoring pod for monitoring environmental indicators in the greenhouse by a moving beam. The moving beam can move along the greenhouse cross beam and can be transferred between the cross beams of the greenhouse. The wire reelers at both ends of the moving beam control the position of the monitoring pod by winding and unwinding the wire ropes, and can place the monitoring pod on the ground at the required position in the intelligent greenhouse for monitoring soil indicators, expanding the monitoring range of air and soil in the intelligent greenhouse, and effectively improving the monitoring ability of the monitoring device for various environmental indicators in the intelligent greenhouse;

[0031] 2. The present invention suspends a mounting box at the bottom end of the moving beam, and a universal ball seat and connecting rods with ends respectively connected to the universal ball seat are provided between the mounting box and the monitoring pod. When the wire reelers at both ends of the moving beam wind or unwind the wire ropes, the shaking during the movement of the monitoring pod can be minimized as much as possible, so that the monitoring pod keeps vertically downward under its own gravity;

[0032] 3. The present invention is provided with an air temperature and humidity meter in the monitoring pod to monitor the temperature and humidity environment at various locations in the intelligent greenhouse, and a photosensor installed on the mounting box is used to monitor the light intensity at various locations in the intelligent greenhouse. After the telescopic box contacts the soil, when the monitoring pod continues to descend, the soil monitor can be inserted into the soil of the intelligent greenhouse to monitor the temperature, humidity, and conductivity of the soil at various locations in the intelligent greenhouse, thereby obtaining more comprehensive environmental indicators in the intelligent greenhouse;

[0033] 4. The present invention fixedly connects a bottom plate to the bottom end of the telescopic box, uses the perforation on the bottom plate for the probe of the soil monitor to pass through, and sets an inverted conical annular scraping blade in the perforation. During the process of the monitoring pod ascending and the probe of the soil monitor being pulled out of the soil, the scraping blade can scrape off the soil on the surface of the probe, improving the data accuracy of subsequent soil environment monitoring;

[0034] 5. The present invention fixedly connects support feet to the bottom end of the telescopic box, enabling the telescopic box to support the ground in the intelligent greenhouse by means of the support feet, and thus forming a ventilated channel on both sides at the bottom end of the telescopic box. During the downward movement of the monitoring pod, the air in the telescopic box blows towards the ground through the perforation on the bottom plate, which can blow away impurities such as fallen leaves on the soil surface in the area where the probe of the soil monitor is about to be inserted, further improving the data accuracy of soil environment monitoring.

Specific embodiments

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0046] The embodiments of the present invention will be described below according to the overall structure of the present invention.

[0047] Embodiment 1

[0048] An intelligent greenhouse monitoring device controlled by a computer, as Figures 1-9 shown, includes a first slide rail 101, the first slide rail 101 is connected below the cross beam 1 of the intelligent greenhouse, a guide rail 2 is arranged along the length direction of the intelligent greenhouse at the middle part of the top of the cross beam 1, a moving table 3 is slidably arranged in the guide rail 2. Specifically, a driving component for driving the moving table 3 to move and position along the guide rail 2 is arranged in the moving table 3. In a large intelligent greenhouse with a long length, multiple moving tables 3 can be arranged, and multiple moving tables 3 correspond to multiple moving beams 5 to better complete the environmental monitoring task in the large intelligent greenhouse. A second slide rail 301 is connected below the moving table 3, the first slide rail 101 and the second slide rail 301 can be communicated with each other. It further includes a moving beam 5, the moving beam 5 can move along the first slide rail 101 and the second slide rail 301 under the drive of the driving component. Wire reels 6 are connected to both ends of the moving beam 5. It also includes a monitoring pod 10 for monitoring the environmental indicators in the intelligent greenhouse. The top of the monitoring pod 10 is connected to the wire reel 6 through a connecting component. Specifically, the connecting component includes a hanging box 7.

[0049] Please refer to Figures 3-4, a movable plate 4 is fixedly connected to the top of the middle part of the movable beam 5. Both sides of the movable plate 4 are rotatably connected to mounting frames 401. The mounting frames 401 are rotatably connected to the movable plate 4 and are used for the intelligent greenhouse cross beam 1 that can adapt to different bending arcs. The mounting frames 401 are rotatably connected to driving wheels 402 that can be in close contact with the bottom surface of the first slide rail 101. Both ends of the top of the mounting frames 401 are fixedly connected to auxiliary rods 404. The top ends of the auxiliary rods 404 are rotatably connected to auxiliary wheels 405 that can be in close contact with the top surface of the first slide rail 101. A driving motor 403 for controlling the driving wheels 402 is fixedly installed on one side of the mounting frames 401. The positioning of the movable plate 4 is realized by the friction force generated by the static driving wheels 402 and auxiliary wheels 405 being in close contact with the first slide rail 101 on the cross beam 1. When the driving motor 403 works to make the driving wheels 402 rotate, the movable plate 4 can be controlled to move along the first slide rail 101. When the first slide rail 101 is aligned with the second slide rail 301, the movable plate 4 can directly move onto the second slide rail 301 along the first slide rail 101 and then move onto the first slide rail 101 on the other side of the cross beam 1 after passing through the second slide rail 301. When the movable beam 5 needs to be transferred between adjacent cross beam supports, after the movable plate 4 slides onto the second slide rail 301 of the transfer platform 3, the transfer platform 3 moves along the guide rail 2 to the cross beam 1 where the transfer is required. After aligning the second slide rail 301 of the transfer platform 3 with the first slide rail 101 of this cross beam 1, the driving motor 403 works to complete the transfer of the position of the movable beam 5.

[0050] Please refer to FIGS. 3 - 5. Both ends of the movable beam 5 are connected to fixed boxes 501. The fixed boxes 501 are rotatably connected to rotating platforms 502. A wire winder 6 is installed on the rotating platforms 502. The bottom end of the rotating platform 502 rotatably connected by the fixed box 501 is connected to a counterweight. The counterweight on the rotating platform 502 keeps the outlet direction of the wire 601 of the wire winder 6 always downward during the movement of the movable beam 5, and as much as possible keeps the direction of the tension of the wire 601 stable. In order to make the monitoring range of the monitoring pod 10 cover all positions inside the intelligent greenhouse, the length of the movable beam 5 is greater than the distance between the cross beams 1. The monitoring pod 10 can move within the length range of the movable beam 5. Since the movable beam 5 can move along the first slide rail 101 and the second slide rail 301, the actual movement range of the monitoring pod 10 can cover most areas inside the intelligent greenhouse.

[0051] Please refer to Figures 1-7, a wire winder 6 winds a guy wire 601. The end parts of the guy wires 601 wound by the two wire winders 6 are respectively connected to both ends of the top of a mounting box 7. A monitoring pod 10 is connected below the mounting box 7. The environmental index monitoring devices arranged in the monitoring pod 10 include an air temperature sensor and an air humidity sensor. Further, sensors such as a carbon dioxide concentration monitor can also be installed in the monitoring pod 10. A vertically downward soil monitor 13 is also installed at the bottom end of the monitoring pod 10. Specifically, the bottom end of the soil monitor 13 has three probes inserted into the soil, which can monitor the humidity, temperature, and conductivity in the soil. A photosensor 12 is installed on the top surface of the mounting box 7. The photosensor 12 is installed at the top of the mounting box 7 to minimize the light shielding by components such as the monitoring pod 10 or the connecting rod 9, so as to obtain more accurate monitoring data. By moving the moving beam 5 and winding and unwinding the wire by the wire winder 6, the position of the monitoring pod 10 is controlled to monitor the air indexes at various positions in the intelligent greenhouse. At the same time, the monitoring pod 10 can also be placed on the bottom surface of the intelligent greenhouse, and the probes of the soil monitor 13 are inserted into the soil to further monitor the soil indexes in the intelligent greenhouse.

[0052] Please refer to Figures 6-9 , the monitoring pod 10 is slidably connected with a telescopic box 11. The bottom end of the telescopic box 11 is fixedly connected with a bottom plate 14. A plurality of through holes 1401 for the probes of the soil monitor 13 to pass through are arranged at intervals on the bottom plate 14. A cleaning component for cleaning the soil adhered to the probes of the soil monitor 13 is arranged in the through holes 1401. The cleaning component on the bottom plate 14 automatically completes the cleaning of the probes each time the probes of the soil monitor 13 are pulled out of the soil.

[0053] Embodiment 2

[0054] An intelligent greenhouse monitoring device controlled by a computer, as Figures 1-9 shown, on the basis of Embodiment 1, the difference from Embodiment 1 is that hanging rings 701 are rotatably connected to both ends of the top of the mounting box 7. The end part of the guy wire 601 of the wire winder 6 is connected to the hanging ring 701. Corresponding universal ball seats 8 are fixedly connected between the bottom surface of the mounting box 7 and the top surface of the monitoring pod 10. The two universal ball seats 8 are connected by a connecting rod 9. The end part of the connecting rod 9 is rotatably connected in the universal ball seat 8. Friction sheets that rub against the connecting rod 9 are pasted on the inner wall of the universal ball seat 8 to improve the stability of the monitoring pod 10 during movement. The rotatable connection between the hanging ring 701 and the mounting box 7 can keep the mounting box 7 as stable as possible when the guy wire 601 extends or shortens, reducing the sway of the mounting box 7 in the horizontal direction. The universal ball shaft structure can make the soil monitor 13 at the bottom end of the monitoring pod 10 always face the ground, facilitating the better insertion of the soil monitor 13 into the soil in the intelligent greenhouse.

[0055] Since the end of the wire 601 is connected to the hanging ring 701, when one of the wire reels 6 releases the wire 601 to make the corresponding wire in a slack state, the mounting box 7 is pulled by the other wire 601 and hangs vertically directly below the wire reel 6 corresponding to the wire 601. The computer can make the moving beam 5 move intermittently through a set program, control the wire winding and unwinding of the wire reels 6 at both ends of the moving beam 5, and thus control the spatial position of the monitoring pod 10.

[0056] Embodiment III

[0057] An intelligent greenhouse monitoring device controlled by a computer, as Figures 1-9 shown. On the basis of Embodiment II, the difference from Embodiment II is that both ends of the bottom of the telescopic box 11 are fixedly connected with support feet 1102 extending downward. The bottom ends of the support feet 1102 are lower than the bottom surface of the bottom plate 14. The inner wall of the telescopic box 11 is in contact with the outer wall of the monitoring pod 10. A sealing rubber ring in contact with the inner wall of the telescopic box 11 is fixedly connected to the bottom end of the monitoring pod 10. The support feet 1102 keep the bottom plate 14 away from the soil surface, and the gas blown out from the through hole 1401 can better blow away the impurities in the area where the probe of the soil monitor is to be inserted.

[0058] Please refer to Figures 6-7 , a guiding groove 1001 is provided on the side wall of the monitoring pod 10. A guiding block 1101 for sliding in the guiding groove 1001 is fixedly connected to the top end of the telescopic box 11. When the guiding block 1101 slides to the bottom end in the guiding groove 1001, the probe of the soil monitor 13 does not extend into the through hole 1401. After the support feet 1102 at the bottom end of the telescopic box 11 contact the ground, the monitoring pod 10 moves downward relative to the telescopic box 11, compresses the air inside the telescopic box 11 to discharge it downward from the through hole 1401, and blows away the impurities in the area where the probe of the soil monitor 13 is to be inserted, effectively improving the data accuracy of the soil monitor 13. The cooperation between the guiding groove 1001 and the guiding block 1101 enables the telescopic box 11 to slide vertically relative to the monitoring pod 10 stably. At the same time, the guiding block 1101 plays a role in limiting the telescopic box 11, avoiding the situation where the telescopic box 11 and the monitoring pod 10 are separated from each other after the monitoring pod 10 is lifted.

[0059] When monitoring the soil indicators in the intelligent greenhouse, the wire reel 6 releases the wire 601 to make the support feet 1102 contact the soil. Subsequently, the wire reel 6 continues to release the wire 601, and the probe of the soil monitor 13 below the monitoring pod 10 passes through the perforation 1401 and then inserts into the soil to monitor the temperature, humidity, and conductivity of the soil. After completing the soil environment monitoring in an area, the wire reel 6 winds up the wire 601 to raise the monitoring pod 10. The probe of the soil monitor 13 moves relative to the cleaning component in the perforation 1401, and the cleaning component makes the soil adhered to the outer wall of the probe fall off. After the guiding block 1101 contacts the bottom end of the guiding groove 1001, as the monitoring pod 10 continues to move upward, the bottom end of the telescopic box 11 also leaves the ground, and then it is lifted to the next place where the soil environment indicators need to be monitored.

[0060] Please refer to Figures 1-2 、 Figures 6-9 A light-transmitting plate 1103 is fixedly connected to the side wall of the telescopic box 11. The light-transmitting plate 1103 is beneficial to observing the situation inside the telescopic box 11. At the same time, when the telescopic box 11 does not contact the ground, it can use light to raise the temperature inside the telescopic box 11, so that the moisture on the surface of the probe of the soil monitor 13 evaporates quickly, avoiding affecting the next soil environment data collection. After the soil monitor 13 completes the monitoring of the soil indicators, when the monitoring pod 10 moves upward, since there is a sealing rubber ring between the bottom end of the monitoring pod 10 and the inner wall of the telescopic box 11, and the air inlet of the telescopic box 11 is at the perforation 1401, and the probe of the soil monitor 13 passes through the perforation 1401 at this time, the air intake speed inside the telescopic box 11 is slower at this time. The monitoring pod 10 directly lifts the telescopic box 11 away from the ground by using negative pressure, and the probe of the soil monitor 13 is pulled out of the soil. During the slow air intake process in the telescopic box 11, the cleaning component in the perforation 1401 slides relative to the outer wall of the probe of the soil monitor 13, scraping off the soil adhered to the probe of the soil monitor 13, avoiding excessive intake of humid air near the ground or accumulated water on the ground into the telescopic box 11, which is beneficial to the probe of the soil monitor 13 quickly returning to a dry state and is beneficial to extending the service life of the probe of the soil monitor 13.

[0061] Please refer to Figures 6-9 A conical ring-shaped scraping blade 1402 is arranged in the perforation 1401. Other cleaning components such as a brush can also be used. Specifically, the scraping blade 1402 is made of rubber, has a certain elasticity, and can effectively scrape off the soil adhered to the outer wall of the probe of the soil monitor 13 or part of the moisture in the soil. The diameter of the bottom opening of the ring-shaped scraping blade 1402 is smaller than the diameter of the probe of the soil monitor 13. The ring-shaped scraping blade 1402 can closely adhere to the outer wall of the probe during the process of the probe of the soil monitor 13 being retracted into the telescopic box 11, scraping off impurities such as soil adhered to the outer wall of the probe.

[0062] The working principle of the present invention is as follows: The moving beam 5 moves along the width direction under the cross beam 1 by means of a driving assembly on the moving plate 4 that cooperates with the first slide rail 101 and the second slide rail 301. When the moving beam 5 needs to be transferred to another cross beam 1, the moving plate 4 first moves onto the second slide rail 301, and the moving platform 3 moves along the guide rail 2 to align the second slide rail 301 with the first slide rail 101 of the target cross beam 1. When the hanging box 7 is directly below the moving plate 4, the wire reelers 6 at both ends of the moving beam 5 simultaneously take in wire at the same speed, which can make the hanging box 7 rise vertically. Conversely, when releasing wire simultaneously at the same speed, the hanging box 7 will descend vertically. When the wire taking-in speeds of the two wire reelers 6 are inconsistent, the hanging box 7 moves obliquely upward in the direction of the wire reeler 6 with a faster wire taking-in speed. When one of the wire reelers 6 does not work and the other wire reeler 6 releases wire, the hanging box 7 moves obliquely downward in the direction of the non-working wire reeler 6. By controlling the wire taking-in and releasing speeds of the two wire reelers 6, the movement of the hanging box 7 can be controlled. Combining with the movement of the moving beam 5, the spatial position of the monitoring pod 10 can be controlled, so as to accurately monitor the environmental indexes at various positions in the intelligent greenhouse.

[0063] Although the embodiments of the present invention have been shown and described, the specific embodiments are only explanations of the present invention and not limitations thereof. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations that do not contribute creatively to the embodiments according to needs, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
