Description

Technical Field

[0001] This invention relates to the field of agricultural information technology, and in particular to a wireless monitoring system for field agricultural information. Background Technology

[0002] With the development of modern agricultural information technology, real-time and efficient wireless monitoring of the field environment has become an important means of precision agricultural management. Common outdoor monitoring devices typically integrate multiple functions such as solar power supply, image acquisition, and environmental sensing. However, these devices are exposed to complex outdoor environments for extended periods, facing multiple challenges including equipment cleanliness, energy supply stability, and structural robustness.

[0003] Specifically, existing monitoring devices, such as the outdoor-use monitoring device disclosed in patent (publication number CN220399392U), focus on the protection and sampling of the atmospheric monitoring sensor unit. This device accelerates airflow and prevents dust from entering by installing ventilation pipes on both sides of the protective casing and incorporating motor-driven fan blades and dust filters, thereby ensuring the accuracy of the monitoring data. This existing technical solution primarily addresses the dustproofing and sampling issues of the monitoring sensor itself.

[0004] However, existing technologies have significant shortcomings for more comprehensive and integrated wireless monitoring systems for field agriculture. First, the solar panels, the system's primary energy source, easily accumulate dust, bird droppings, and other contaminants in outdoor environments, severely impacting their photoelectric conversion efficiency. Current technologies lack efficient and automated cleaning solutions for solar panels. Second, the monitoring cameras, as key information acquisition units, also require regular cleaning to ensure image clarity. Existing cleaning solutions are often independent and limited in function, unable to integrate with other parts of the system (such as water supply units), resulting in poor cleaning effectiveness or low resource utilization efficiency. Finally, for pole-mounted monitoring devices installed in the field and subjected to wind loads, the overall wind resistance and stability of the structure are crucial. Existing technologies often use simple poles or fixed bases, which struggle to provide sufficient and adjustable support in soft soil or uneven terrain, and lack designs that integrate with the upper support structure, thus requiring improved stability.

[0005] Therefore, there is an urgent need in this field for an integrated wireless monitoring system for field agriculture that can achieve energy self-sufficiency, efficient self-cleaning of key equipment, and a robust and reliable overall structure, in order to overcome the aforementioned shortcomings of existing technologies. Summary of the Invention

[0006] The main objective of this invention is to overcome the shortcomings of the prior art and provide a wireless monitoring system for field agriculture information.

[0007] The technical solution adopted by the present invention to achieve its technical objective is: a wireless monitoring system for field agriculture information, including a pole, a water tank being provided at the top of the pole, and a top plate being provided above the water tank; A solar panel is installed on the top plate, and a scraper that can move back and forth to clean the solar panel is provided on the top plate; It also includes a surveillance camera, and a cleaning plate that can rotate to clean the surveillance camera is provided next to the surveillance camera; The monitoring camera is equipped with a nozzle, which is connected to the water tank via a miniature water pump.

[0008] Preferably, a slotted plate is fixedly connected to the bottom end of the top plate, a threaded sleeve that is threadedly connected to the lead screw is fixedly connected to one end of the scraper, and a slider that is slidably engaged in the slotted plate is fixedly connected to the other end; the lead screw is connected to a drive motor that drives its rotation.

[0009] Preferably, the card slot plate is configured as a right-angled trapezoidal structure.

[0010] Preferably, the two ends of the card slot plate are open.

[0011] Preferably, the cleaning plate is configured as an arc-shaped plate, and the rotating rod of the cleaning plate is connected to a servo motor.

[0012] Preferably, a spray pipe is also provided on the top plate, and the spray pipe is connected to the water pump inside the water tank through a delivery pipe.

[0013] Preferably, the pole is provided with a support assembly, which includes a clamp sleeved on the pole and a support rod hinged to the clamp.

[0014] Preferably, a positioning ring for supporting the clamp is fixedly sleeved on the outer wall of the rod.

[0015] Preferably, the bottom end of the support rod is hinged to a positioning seat plate, which is snapped onto an annular plate on the fixed base.

[0016] Preferably, the top plate is configured as a triangular structure.

[0017] The working principle of this wireless monitoring system for field agriculture information is as follows: The system uses a pole as its main support, with a water tank at the top providing the cleaning water source. Solar panels are mounted on the top plate. A drive motor rotates a lead screw, causing a scraper threaded onto the solar panel surface to reciprocate, achieving cleaning. The scraper's movement is guided by a slider at one end sliding within a slot plate. Simultaneously, a servo motor rotates an arc-shaped cleaning plate to clean the camera lens. During this process, a miniature water pump draws water from the tank and sprays it onto the cleaning plate through nozzles on the camera, performing wet cleaning to enhance the cleaning effect. Alternatively, the system can directly rinse the solar panels through spray pipes on the top plate. To improve overall system stability, the pole is fixed to the ground via a base at its base and further supported by a support assembly. This support assembly is secured to the pole with clamps and is stabilized by a support rod and positioning plate connected to a ring-shaped clamp on the base.

[0018] Compared with the prior art, the beneficial effects of the present invention are: This wireless monitoring system for field agriculture has achieved automated and collaborative cleaning of key equipment. By integrating an automatic scraping mechanism for solar panels and a rotating cleaning mechanism for monitoring cameras that is linked to water spraying, and utilizing the system's built-in water tank for water supply, it has achieved efficient wet cleaning, solving the problem of performance degradation caused by dust accumulation on solar panels and lenses in existing technologies.

[0019] This wireless monitoring system for field agriculture provides an adjustable, multi-level linked, enhanced and stable structure. By designing an expandable bottom fixed base and connecting it to the central support components via a snap-fit ​​structure to form a rigid triangular support, the system significantly improves the pole's wind resistance and overall stability in complex field conditions, overcoming the shortcomings of traditional simple support structures such as poor adaptability and insufficient stability.

[0020] This wireless monitoring system for field agriculture is a highly integrated, functionally interconnected, and self-sustaining system. By organically integrating energy harvesting, water circulation and cleaning, information monitoring, and a physically stable structure, the various subsystems work together to form a comprehensive monitoring terminal with low maintenance requirements and strong environmental adaptability, effectively improving the reliability of long-term field operations.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0030] In the description of this invention, it should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to or indirectly connected to the other element.

[0031] In the description of this invention, it should be noted that the terms "center," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are used only for the convenience of describing the invention and for 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 the invention. Furthermore, the terms "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. "Several" means one or more, unless otherwise explicitly specified.

[0032] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Example 1:

[0033] Please see Figures 1-4 A wireless monitoring system for field agriculture includes a pole 11, a water tank 1 fixedly installed on the top of the pole 11, water inlet pipes 101 fixedly connected to both sides of the water tank 1, a pipe cover 102 fixedly installed at one end of the water inlet pipe 101, and an interference fit connection between the pipe cover 102 and the port of the water inlet pipe 101.

[0034] A triangular top plate 2 is fixedly installed on the top of the water tank 1 via a connecting plate 7. A slot plate 204 is fixedly connected to the bottom of the top plate 2. The triangular structure of the top plate 2 facilitates the rolling off of rainwater and dust, and prevents water or dust accumulation.

[0035] Multiple solar panels 8 are fixedly installed on the top plate 2. A scraper 201 is attached to one side of the solar panel 8. One end of the scraper 201 is fixedly connected to a threaded sleeve 206, and the other end is fixedly connected to a slider 205. A lead screw 202 is threadedly connected inside the threaded sleeve 206. The two ends of the lead screw 202 are rotatably connected to the top of the top plate 2 through a first mounting plate. The slider 205 is slidably engaged inside the slot plate 204. One end of the scraper 201 is threadedly connected to the lead screw 202 through the threaded sleeve 206, and the other end is restricted inside the slot plate 204 by the slider 205. Thus, by rotating the lead screw 202, the lead screw 202 can drive the scraper 201 and the slider 205 to move and clean the solar panels 8.

[0036] It should be noted that the slot plate 204 is designed as a right-angled trapezoidal structure, so the slider 205 can match the shape and structural characteristics of the slot plate 204, and the two can slide and engage.

[0037] One end of the lead screw 202 is fixedly connected to a drive motor 203, which is a reciprocating motor and is fixedly mounted on the first mounting plate. The drive motor 203 drives the lead screw 202 to rotate. The lead screw 202 is threadedly connected to the inside of the threaded sleeve 206, so that when the lead screw 202 rotates, it drives the scraper 201 and the slider 205 to reciprocate.

[0038] A monitoring camera 6, a servo motor 4, and a cleaning plate 401 with a rotating rod are fixedly installed on one side of the connecting plate 7. The rotating rod of the cleaning plate 401 is fixed to the drive shaft of the servo motor 4. The servo motor 4 drives the cleaning plate 401 to rotate, and the cleaning plate 401 cleans the monitoring camera 6.

[0039] The cleaning plate 401 is set as an arc-shaped plate. When not cleaning, the cleaning plate 401 is located below the top of the top plate 2.

[0040] Furthermore, in this embodiment, the card slot plate 204 is supported on the water tank 1 by the support plate 5. The two ends of the card slot plate 204 are open, and the slider 205 can pass through the two ends of the card slot plate 204. The two ends of the card slot plate 204 are open, and the dust or debris inside the card slot plate 204 is cleaned out by the movement of the scraper 201 and the slider 205 to avoid accumulation.

[0041] Furthermore, in this embodiment, nozzles 601 are fixedly installed on both sides of the upper end of the monitoring camera 6, with the nozzles 601 facing the cleaning plate 401. A miniature water pump 603 is integrally installed at one end of the nozzle 601, and the miniature water pump 603 is connected to the nozzle 601. The miniature water pump 603 is connected to the water tank 1 through a hose 602. When the cleaning plate 401 is cleaning the monitoring camera 6, the miniature water pump 603 draws water from the water tank 1 and sprays it out through the nozzles 601 towards the cleaning plate 401, so that water can be sprayed onto the cleaning plate 401 to assist in cleaning.

[0042] It should be noted that, in order to conserve water, a sensor can be installed at the location of the monitoring camera 6 on the sweeping plate 401. The sensor is electrically connected to the miniature water pump 603, controlling the intermittent start of the miniature water pump 603. When the sweeping plate 401 moves to the position of the monitoring camera 6, the sensor recognizes the sweeping plate 401, thereby energizing the miniature water pump 603 and spraying water onto the sweeping plate 401. This intermittent energization via the sensor can be implemented using existing technology, and its detailed structure will not be elaborated upon here.

[0043] Specifically, in use, the drive motor 203 drives the lead screw 202 to rotate, causing the scraper 201 and slider 205 to reciprocate. When the scraper 201 moves, it cleans the solar panel 8, while the slider 205 moves, removing dust or debris from inside the slot plate 204 to prevent accumulation. Furthermore, the servo motor 4 drives the cleaning plate 401 to rotate. Figure 1 The dotted circle in the middle represents the rotation trajectory of the cleaning plate 401. The cleaning plate 401 can clean the monitoring camera 6. At the same time, when the cleaning plate 401 is cleaning the monitoring camera 6, the miniature water pump 603 draws water from the water tank 1 and sprays it towards the cleaning plate 401 through the nozzle 601, so that the water can be sprayed onto the cleaning plate 401 to assist in the cleaning. Implementation: 2:

[0044] Please see Figures 1-4 Based on the above embodiments, the field agricultural information wireless monitoring system has spray pipes 3 on both sides of the screw 202. The spray pipes 3 are fixed to the top of the top plate 2 by the second mounting plate. One end of the spray pipe 3 is fixedly connected to the conveying pipe 301, and one end of the conveying pipe 301 is fixedly connected to the water pump inside the water tank 1. Water is pumped through the water pump inside the water tank 1 (not shown in the figure) through the delivery pipe 301 into the spray pipe 3, and then discharged through the spray pipe 3 onto the solar panel 8 to clean the solar panel 8.

[0045] Specifically, in use, during prolonged periods without rain or when the solar panel 8 needs to be washed, water is pumped from the water tank 1 into the spray pipe 3 to wash the solar panel 8. At the same time, the scraper 201 moves back and forth to clean the solar panel 8.

[0046] The solution in this embodiment can be selectively combined with solutions in other embodiments. Implementation: 3:

[0047] Please see Figure 1 , Figure 7 Based on the above embodiments, the field agricultural information wireless monitoring system has a support component 10 at the upper middle end of the pole 11. One end of the support component 10 is sleeved on the pole 11, and the other end is connected to the fixed base 9. The support component 10 includes a clamp 1001, a combination bolt 1002, a support rod 1003, a positioning base plate 1004, a positioning ring 1005, and an annular clamping plate 1006.

[0048] Two sets of clamps 1001 are provided. After being locked and fixed by combination bolts 1002, clamps 1001 are fixedly sleeved on the outer wall of the upper middle end of the rod body 11. Support rods 1003 are hinged to both sides of the outer wall of clamps 1001. Positioning seat plate 1004 is hinged to the bottom end of support rod 1003. Positioning seat plate 1004 is snapped onto annular clamp plate 1006.

[0049] A positioning ring 1005 is fixedly sleeved on the outer wall of the rod 11. When the clamp 1001 is fixed on the outer wall of the rod 11 through the positioning ring 1005, the clamp 1001 is supported, thereby reducing the fastening pressure between the clamp 1001 and the rod 11.

[0050] It should be noted that, in order to facilitate the installation of the support rod 1003 and the cooperation between the support rod 1003 and the annular clamping plate 1006, the support rod 1003 can be set as a telescopic rod, and telescopic connection can be made by screws, bolts, holes, inner sleeves and outer sleeves. Existing technology can be used for operation and arrangement here, which will not be described in detail.

[0051] The solution in this embodiment can be selectively combined with solutions in other embodiments. Implementation: 4:

[0052] Please see Figure 1 , Figure 5 , Figure 6 , Figure 7Based on the above embodiments, the field agricultural information wireless monitoring system has a fixed base 9 at the bottom of the pole 11, which is fixed to the ground. The fixed base 9 includes a convex plate 901, a convex groove 902, a sliding plate 903, a pin 904, a rotating plate 905, a track groove 906, an extension plate 907, and a fitting groove 908.

[0053] The bottom of the convex disc 901 is fixed to the ground by long bolts / anchors, and the top is evenly provided with multiple convex grooves 902. There can be six convex grooves 902. One side of the convex groove 902 is semi-open to facilitate the connection between the slide plate 903 and the pin 904. The slide plate 903 is slidably engaged inside the multiple convex grooves 902. One end of the slide plate 903 is fixedly connected to the pin 904, and the other end is fixedly provided with an extension plate 907. The extension plate 907 is designed with an arc shape, and multiple extension plates 907 can be combined to form a ring structure, which fits against the side wall of the bottom part of the convex disc 901.

[0054] The top of the convex disk 901 is rotatably connected to a rotating disk 905. The rotating disk 905 has multiple track grooves 906 corresponding to the number of pins 904 inside. The track grooves 906 are arc-shaped and inclined. The pins 904 are located in the track grooves 906, and the top of the pins 904 is flush with the top of the convex disk 901.

[0055] The bottom of the rod 11 and the top of the rotating disk 905 are fixedly connected by a flange, so that the rod 11 is installed on the fixed base 9 and finally stands on the ground.

[0056] Furthermore, in this embodiment, each of the multiple expansion plates 907 has a mating groove 908 inside, and the multiple mating grooves 908 are combined to form a ring structure; the mating groove 908 is set as an arc-shaped structure, and when the multiple expansion plates 907 expand and unfold at the same time, the multiple mating grooves 908 can be combined to form a discontinuous ring structure.

[0057] When multiple mating grooves 908 are combined to form a ring structure, a ring-shaped retaining plate 1006 is placed inside the mating grooves 908. One end of the ring-shaped retaining plate 1006 is clamped in the multiple mating grooves 908 by an interference fit, and the other end is connected to the support assembly 10. The positioning seat plate 1004 in the support assembly 10 is clamped on the ring-shaped retaining plate 1006 by an interference fit.

[0058] Specifically, in use, by rotating the rotating disk 905, it can simultaneously drive multiple pins 904 to move along the track through the track groove 906. Since the sliding plate 903 is slidably engaged inside the convex slide groove 902, the pins 904 drive the sliding plate 903 to move synchronously within the convex slide groove 902. This allows multiple expansion plates 907 to expand and unfold simultaneously to support the ground, or to retract and close into a ring structure that fits against the bottom side wall of the convex disk 901. When multiple expansion plates 907 expand and unfold simultaneously, the support range of the fixed base 9 is expanded.

[0059] Simultaneously, when multiple expansion plates 907 expand and unfold at the same time, multiple mating grooves 908 can combine to form a discontinuous annular structure. When multiple mating grooves 908 combine to form an annular structure, an annular locking plate 1006 is placed in the mating groove 908. One end of the annular locking plate 1006 is locked in the multiple mating grooves 908 by interference fit, and the other end is locked with the positioning seat plate 1004 in the support assembly 10 by interference fit, so that the support assembly 10 can stably support the rod 11.

[0060] The solution in this embodiment can be selectively combined with solutions in other embodiments.

[0061] The specific usage procedure of this wireless monitoring system for field agriculture information is as follows: The system uses a pole 11 that stands vertically on the ground as the core support structure. A water tank 1 for water storage is fixedly installed on the top of the pole 11. A triangular top plate 2 is installed above it via a connecting plate 7. The system energy is provided by multiple solar panels 8 installed on the top plate 2. To ensure that the solar panels 8 generate electricity efficiently, their cleaning is performed by a reciprocating scraper 201. The drive motor 203 starts and drives the lead screw 202 to rotate. The scraper 201, which is connected to the lead screw 202 through the threaded sleeve 206, moves horizontally. At the same time, the slider 205 at the other end of the scraper 201 slides and is guided in the slot plate 204 fixed to the bottom of the top plate 2, thereby realizing the automatic cleaning of the scraper 201 along the surface of the solar panel 8. The opening design at both ends of the slot plate 204 allows the slider 205 and the scraped dust and debris to move out, avoiding accumulation.

[0062] The system's information collection is completed by the monitoring camera 6, and its cleaning is achieved by the servo motor 4 driving the arc-shaped cleaning plate 401 to rotate periodically. In order to improve the cleaning effect, when the cleaning plate 401 rotates to the front of the monitoring camera 6, the micro water pump 603 starts, pumping the water in the water tank 1 through the hose 602 to the nozzle 601, spraying it onto the cleaning plate 401, and wet-wiping the lens of the monitoring camera 6. In addition, when deep cleaning is required, the water pump in the water tank 1 can be started to deliver water through the delivery pipe 301 to the spray pipe 3 on the top plate 2 to spray and rinse the surface of the solar panel 8, and can work in conjunction with the mechanical cleaning of the scraper 201.

[0063] To enhance the system's wind resistance and overall stability in the field, an expandable fixed base 9 is installed at the bottom of the pole 11. By rotating the rotating disk 905, multiple extension plates 907 can be driven to expand outward synchronously to increase the grounding area. Meanwhile, a support assembly 10 can be installed on the upper part of the rod 11, which is fixed to the rod 11 by a clamp 1001. The bottom end of the support rod 1003 is snapped onto the annular clamp 1006 of the fixed base 9 by a positioning seat plate 1004, forming a triangular stable support structure. The positioning ring 1005 is sleeved on the rod 11 to share the downward pressure on the clamp 1001.

[0064] The entire system achieves integrated wireless monitoring functions, including energy self-sufficiency, automatic cleaning of key equipment, and structural stability.
