Technical Field

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

[0002] Smart greenhouse refers to the application of intelligent control systems to greenhouse cultivation, creating the most suitable environmental conditions for the growth of crops in the greenhouse, using monitoring devices to collect various environmental indicators of the greenhouse such as temperature, humidity, carbon dioxide, light intensity, etc., and using computers to analyze the data. The computer controls the water curtains, fans, sunshades and other facilities in the greenhouse, thereby changing the biological growth environment inside the greenhouse.

[0003] A Chinese patent with the relevant announcement number CN117629308A discloses a monitoring device for an intelligent greenhouse, which is fixedly installed on the greenhouse frame and includes an inspection structure, a lifting structure, a control structure and a supporting beam. It uses the monitoring instrument and the pulley's own gravity to perform reciprocating activities inside the slide rail to achieve dynamic monitoring of the monitoring process with zero drive. The lifting structure can be used to adjust the monitoring height within a range, and the slide rail length can be designed according to the requirements of the monitoring area.

[0004] With respect to the above-mentioned related technologies, the prior art sets a monitoring device that can move in the vertical direction and adjust the height in the middle of the greenhouse. The monitoring range of the monitoring device is the central area of ​​the greenhouse along the length direction, and it is not easy to monitor environmental indicators at the edge of the smart greenhouse and in the soil.

[0005] A Chinese patent with the relevant announcement 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 fixed ring and a monitoring instrument. The third gear rotates to drive the rotating ring to rotate in a circle through the action of the annular teeth, so that the monitoring instrument can perform multi-directional monitoring.

[0006] With respect to the above-mentioned related technologies, the prior art uses the crossbeams of the smart greenhouse as tracks to set up a monitoring device that can move on the tracks. The monitoring range of the monitoring device is the area near the crossbeams of the smart greenhouse. It is not easy to monitor the position close to the crops in the central area of ​​the smart greenhouse, which easily makes the obtained monitoring data incomplete, and it is also impossible to monitor the soil indicators in the greenhouse. The cost of slidingly connecting the monitoring device in the prior art on the crossbeams of each greenhouse is also high.

[0007] In summary, the existing intelligent greenhouse monitoring devices controlled by computers can monitor limited environmental indicators, and the monitoring data obtained is not comprehensive. Summary of the invention

The present invention suspends a mounting box at the bottom end of the moving beam, and arranges a universal ball seat and a connecting rod whose ends are respectively connected to the universal ball seat between the mounting box and the monitoring pod. When the wire take-ups at both ends of the moving beam are reeling in or releasing wires, the shaking of the monitoring pod during movement can be reduced as much as possible, so that the monitoring pod is kept in a vertical downward state due to its own gravity; 3. The present invention arranges an air temperature and humidity meter in the monitoring pod to monitor the temperature and humidity environment at various places in the smart greenhouse, and uses the photoreceptor installed on the mounting box to monitor the light intensity at various places in the smart greenhouse. After the telescopic box contacts the soil, the monitoring pod continues to descend to allow the soil monitor to be inserted into the soil of the smart greenhouse, and the temperature, humidity and conductivity of the soil at various places in the smart greenhouse are monitored, thereby obtaining more comprehensive environmental indicators in the smart greenhouse; 4. The present invention fixes a bottom plate at the bottom end of the telescopic box, uses the perforations on the bottom plate for the probe of the soil monitor to pass through, and arranges an inverted cone-shaped annular scraper in the perforations. When the monitoring pod rises and the probe of the soil monitor is pulled out of the soil, the scraper can scrape the soil on the surface of the probe, thereby improving the accuracy of the subsequent soil environment monitoring data; 5. The present invention fixes supporting feet at the bottom of the telescopic box, so that the telescopic box can use the supporting feet to support the ground in the intelligent greenhouse, and then form ventilation channels on both sides of the bottom of the telescopic box. When the monitoring pod moves downward, the air in the telescopic box is blown to the ground through the perforations on the bottom plate, which can blow away impurities such as fallen leaves on the soil surface of the area where the soil monitor probe is to be inserted, further improving the data accuracy of soil environment monitoring.

DETAILED DESCRIPTION

[0032] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] The following describes an embodiment of the present invention based on its overall structure.

[0034] Embodiment 1 An intelligent greenhouse monitoring device controlled by a computer, such as Figure 1-9 As shown, it includes a first slide rail 101, which is connected to the bottom of the crossbeam 1 of the intelligent greenhouse. A guide rail 2 is arranged in the middle of the top of the crossbeam 1 along the length direction of the intelligent greenhouse. A moving platform 3 is slidably arranged in the guide rail 2. Specifically, a driving component for driving the moving platform 3 to move and position along the guide rail 2 is arranged in the moving platform 3. In a large-scale intelligent greenhouse with a long length, multiple moving platforms 3 can be provided, and multiple moving platforms 3 correspond to multiple moving beams 5 to better complete the environmental monitoring task in the large-scale intelligent greenhouse. A second slide rail 301 is connected below the moving platform 3, and the first slide rail 101 and the second slide rail 301 can be connected to each other. It also includes a moving beam 5, which can move along the first slide rail 101 and the second slide rail 301 under the drive of the driving component. A wire take-up device 6 is connected to both ends of the moving beam 5. It also includes a monitoring pod 10 for monitoring environmental indicators in the intelligent greenhouse. The top of the monitoring pod 10 is connected to the wire take-up device 6 through a connecting component. Specifically, the connecting component includes a mounting box 7.

[0035] See also Figure 3-4The top of the middle part of the moving beam 5 is fixedly connected with a moving plate 4, and both sides of the moving plate 4 are rotatably connected with a mounting frame 401, and the mounting frame 401 is rotatably connected to the moving plate 4, which is used to adapt to the intelligent greenhouse beams 1 with different curvatures. The mounting frame 401 is rotatably connected with a driving wheel 402 that can be in close contact with the bottom surface of the first slide rail 101, and both ends of the top of the mounting frame 401 are fixedly connected with an auxiliary rod 404, and the top of the auxiliary rod 404 is rotatably connected with an auxiliary wheel 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 wheel 402 is fixedly installed on one side of the mounting frame 401, and the friction force generated by the close contact between the stationary driving wheel 402 and the auxiliary wheel 405 and the first slide rail 101 on the beam 1 is utilized. To achieve the positioning of the movable plate 4, when the driving motor 403 works to rotate the driving wheel 402, 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 move directly to the second slide rail 301 along the first slide rail 101, and after passing through the second slide rail 301, it can move to the first slide rail 101 on the other side of the beam 1. When the movable beam 5 needs to be transferred on the adjacent beam 1 bracket, after the movable plate 4 slides to the second slide rail 301 of the moving platform 3, the moving platform 3 moves along the guide rail 2 to the beam 1 to be transferred. After the second slide rail 301 of the moving platform 3 is aligned with the first slide rail 101 of the beam 1, the driving motor 403 works to complete the transfer of the position of the movable beam 5.

[0036] Please refer to 3-5, the two ends of the moving beam 5 are connected with fixed boxes 501, the fixed box 501 is rotatably connected with a rotating table 502, a wire take-up device 6 is installed on the rotating table 502, and the bottom end of the rotating table 502 to which the fixed box 501 is rotatably connected is connected with a counterweight block, and the counterweight block on the rotating table 502 makes the wire 601 outlet of the wire take-up device 6 always face downward, and the direction of the pulling force of the wire 601 is kept as stable as possible during the movement of the moving beam 5. In order to make the monitoring range of the monitoring pod 10 cover various positions in the smart greenhouse, the length of the moving beam 5 is greater than the spacing between the beams 1, and the monitoring pod 10 can move within the length range of the moving beam 5. Since the moving beam 5 can move along the first slide rail 101 and the second slide rail 301, the actual moving range of the monitoring pod 10 can cover most areas in the smart greenhouse.

[0037] See also Figure 1-7A pull wire 601 is wound up in the wire take-up device 6, and the ends of the pull wires 601 wound up by the two wire take-ups 6 are respectively connected to the two ends of the top of the mounting box 7, and a monitoring pod 10 is connected to the bottom of the mounting box 7. The environmental indicator monitoring devices provided in the monitoring pod 10 include an air temperature sensor and an air humidity sensor. Furthermore, sensors such as a carbon dioxide concentration monitor can also be installed in the monitoring pod 10. A soil monitor 13 is also installed vertically downward at the bottom of the monitoring pod 10. Specifically, the bottom of the soil monitor 13 has three probes inserted into the soil, which can monitor the soil. Humidity, temperature and conductivity. A photoreceptor 12 is installed on the top surface of the mounting box 7. The photoreceptor 12 is installed on the top of the mounting box 7 to minimize the light blocking by the monitoring pod 10 or the connecting rod 9 and other components, thereby obtaining more accurate monitoring data. The position of the monitoring pod 10 is controlled by the movement of the moving beam 5 and the winding and releasing of the wire reel 6 to monitor the air indicators at various locations in the smart greenhouse. At the same time, the monitoring pod 10 can also be placed on the bottom surface of the smart greenhouse, so that the probe of the soil monitor 13 is inserted into the soil to further monitor the soil indicators in the smart greenhouse.

[0038] See also Figure 6-9 The monitoring pod 10 is slidably connected to a telescopic box 11, and the bottom end of the telescopic box 11 is fixedly connected to a bottom plate 14. A plurality of through holes 1401 for the probe of the soil monitor 13 to pass through are arranged at intervals on the bottom plate 14. A cleaning component for cleaning the soil to which the probe of the soil monitor 13 adheres is arranged in the through hole 1401. The cleaning component on the bottom plate 14 automatically cleans the probe of the soil monitor 13 each time it is pulled out of the soil.

[0039] Embodiment 2 An intelligent greenhouse monitoring device controlled by a computer, such as Figure 1-9 As shown, on the basis of Example 1, the difference from Example 1 is that both ends of the top of the mounting box 7 are rotatably connected with a hanging ring 701, the end of the pull wire 601 of the wire take-up device 6 is connected to the hanging ring 701, and the bottom surface of the mounting box 7 and the top surface of the monitoring pod 10 are fixedly connected with corresponding universal ball sockets 8, and the two universal ball sockets 8 are connected by a connecting rod 9, and the end of the connecting rod 9 is rotatably connected to the universal ball socket 8. The inner wall of the universal ball socket 8 is pasted with a friction plate that rubs against the connecting rod 9, which is used 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 pull wire 601 is extended or shortened, and reduce the shaking of the mounting box 7 in the horizontal direction. The universal ball shaft structure can make the soil monitor 13 at the bottom of the monitoring pod 10 always face the ground, so that the soil monitor 13 can be better inserted into the soil in the smart greenhouse.

[0040] Since the end of the pull wire 601 is connected to the hanging ring 701, when one of the wire take-ups 6 releases the pull wire 601 to keep the corresponding pull wire in a relaxed state, the mounting box 7 is pulled by the other pull wire 601 and hangs down directly below the wire take-up 6 corresponding to the pull wire 601. The computer can set a program to make the moving beam 5 move intermittently, control the wire take-ups 6 at both ends of the moving beam 5 to take up and release the wire, and further control the spatial position of the monitoring pod 10.

[0041] Embodiment 3 An intelligent greenhouse monitoring device controlled by a computer, such as Figure 1-9 As shown, on the basis of Example 2, the difference from Example 2 lies in that the two ends of the bottom of the telescopic box 11 are fixedly connected with downwardly extending support feet 1102, 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, and the bottom end of the monitoring pod 10 is fixedly connected with a sealing rubber ring in contact with the inner wall of the telescopic box 11, the support feet 1102 keep the bottom plate 14 and the soil surface away from each other, and the gas blown out from the perforation 1401 can better blow away impurities in the area where the probe is to be inserted.

[0042] See also Figure 6-7 , a guide groove 1001 is provided on the side wall of the monitoring pod 10, and a guide block 1101 for sliding in the guide groove 1001 is fixedly connected to the top of the telescopic box 11. When the guide block 1101 slides to the bottom of the guide groove 1001, the probe of the soil monitor 13 does not extend into the through hole 1401. After the supporting foot 1102 at the bottom of the telescopic box 11 touches the ground, the monitoring pod 10 moves downward relative to the telescopic box 11, compressing the air inside the telescopic box 11 and discharging it downward from the through hole 1401, blowing away 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, and the cooperation between the guide groove 1001 and the guide block 1101 enables the telescopic box 11 to slide vertically smoothly relative to the monitoring pod 10. At the same time, the guide block 1101 limits the telescopic box 11, thereby preventing the telescopic box 11 and the monitoring pod 10 from separating from each other after the monitoring pod 10 is lifted.

[0043] When monitoring the soil indicators in the intelligent greenhouse, the wire take-up device 6 releases the pull wire 601 to allow the support foot 1102 to contact the soil, and then the wire take-up device 6 continues to release the pull wire 601. The probe of the soil monitor 13 under the monitoring pod 10 passes through the through hole 1401 and is inserted into the soil to monitor the temperature, humidity and conductivity of the soil. After completing the soil environment monitoring in an area, the wire take-up device 6 reels the pull wire 601 to make the monitoring pod 10 rise, and the probe of the soil monitor 13 moves relative to the cleaning component in the through hole 1401. The cleaning component causes the soil adhered to the outer wall of the probe to fall off. After the guide block 1101 contacts the bottom end of the guide groove 1001, as the monitoring pod 10 continues to move upward, the bottom end of the telescopic box 11 also leaves the ground and is then hoisted to the next location where soil environment indicators need to be monitored.

[0044] See also Figure 1-2 , Figure 6-9 The side wall of the telescopic box 11 is fixedly connected with a light-transmitting plate 1103, which is conducive to observing the situation inside the telescopic box 11. At the same time, when the telescopic box 11 is not in contact with the ground, the light can be used to increase 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 soil indicators, when the monitoring pod 10 moves upward, a sealing rubber ring is provided 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 the through hole 1401, and the through hole 1401 passes through The probe of the soil monitor 13, at this time, the air intake speed in the telescopic box 11 is slow, and the monitoring pod 10 uses negative pressure to directly lift the telescopic box 11 off the ground, and the probe of the soil monitor 13 is pulled out of the soil. During the slow air intake 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, and the soil adhered to the probe of the soil monitor 13 is scraped off, avoiding the telescopic box 11 from sucking in too much humid air close to the ground or water on the ground, which is beneficial for the probe of the soil monitor 13 to quickly restore to a dry state, and is beneficial to extending the service life of the probe of the soil monitor 13.

[0045] See also Figure 6-9 An inverted cone-shaped annular scraper 1402 is arranged in the through hole 1401, and other cleaning components such as brushes can also be used to clean. Specifically, the scraper 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 annular scraper 1402 is smaller than the probe diameter of the soil monitor 13. When the soil monitor 13 probe is retracted into the telescopic box 11, the annular scraper 1402 can cling to the outer wall of the probe to scrape off the soil and other impurities adhered to the outer wall of the probe.

[0046] The working principle of the present invention is as follows: the moving beam 5 moves under the beam 1 along the width direction 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 other beams 1, the moving plate 4 first moves to 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 beam 1. When the mounting box 7 is located directly below the moving plate 4, the wire take-ups 6 at both ends of the moving beam 5 simultaneously take up the wires at the same speed, which can make the mounting box 7 rise vertically. Conversely, Paying out the line at the same speed at the same time causes the mounting box 7 to descend vertically. When the take-up speeds of the two wire take-ups 6 are inconsistent, the mounting box 7 moves obliquely upward toward the wire take-up 6 that takes up the line faster. When one of the wire take-ups 6 is not working and the other wire take-up 6 is paying out the line, the mounting box 7 moves obliquely downward toward the non-working wire take-up 6. The movement of the mounting box 7 can be controlled by controlling the take-up and pay-out speeds of the two wire take-ups 6, and the movement of the combined moving beam 5 can further control the spatial position of the monitoring pod 10, thereby realizing accurate environmental index monitoring at various locations in the smart greenhouse.
