Technical Field
[0001] The invention relates to the technical field of monitoring equipment, in particular to an integrated monitoring device for four agricultural conditions. Background Art
[0002] The integrated agricultural monitoring system is an intelligent system integrating IoT, sensors, and data analysis technologies. By integrating IoT sensors, big data analytics, and AI algorithms, it enables comprehensive monitoring and precise control of the farmland environment. Its core functions include real-time monitoring of soil moisture (humidity, temperature, and electrical conductivity) to guide precision irrigation; dynamic assessment of crop growth and optimized management through image recognition and spectral analysis; early warning of pest outbreaks using insect monitoring lights and AI recognition technology; and combined with meteorological data to monitor extreme weather and activate emergency response equipment to mitigate disaster losses. Based on multi-dimensional data fusion, this system provides scientific decision-making support for agricultural production, significantly improving resource utilization and production efficiency, promoting cost reduction, efficiency improvement, and green and sustainable development. It is widely used in fields such as field cultivation and facility agriculture.
[0003] In the existing technology, when the tubular soil moisture sensor is rotated and inserted into the mud, it is easy to form gaps and bubbles between the tubular soil moisture sensor and the soil due to factors such as the imbalance between the rotation speed and the mud viscosity and the rough surface of the fixed hole. In addition, there is generally no corresponding component to eliminate the gaps and bubbles, which causes the gaps and bubbles to destroy the close contact between the soil and the electrode, causing dielectric constant measurement deviation; during single-point or layered monitoring, bubble aggregation causes local humidity data to be falsely low, and the bubbles migrate or burst over time, causing data fluctuations, reducing long-term monitoring stability, and limiting the application efficiency of tubular soil moisture sensors in the field of precision agricultural monitoring.
[0004] Therefore, the present invention provides an integrated agricultural four-condition monitoring device that can eliminate the gaps and bubbles formed between the tubular soil moisture sensor and the soil to ensure the working efficiency of the tubular soil moisture sensor. Summary of the Invention
[0005] Aiming at the problem that it is difficult to eliminate the gaps and bubbles formed between the tubular soil moisture sensor and the soil and to discharge the bubbles when drilling holes and cores in the existing technology, an integrated agricultural four-condition monitoring device is designed.
[0006] The technical solution adopted by the present invention to solve its technical problems is: an integrated agricultural four-condition monitoring device, including a comprehensive data processing module and a tubular soil moisture sensor, and also including a gap filling portion fixed to the outside of the tubular soil moisture sensor, which has an overall double-thread structure. The device is assembled so that when the tubular soil moisture sensor is rotated and inserted into the soil layer, the direction of the mud flow channel is changed to change the direction of the mud flow channel, and the area of the mud flow channel is changed to change the mud flow rate, thereby shearing and destroying cavities or bubbles on the surface of the tubular soil moisture sensor along the axial direction of the tubular soil moisture sensor toward the ground surface; And a guide part opened on the outer wall of the tubular soil moisture sensor forms an axial exhaust channel running through the bottom of the hole. When the tubular soil moisture sensor is rotated and pressed down, the bubbles are filled in the gap and the mud is guided to squeeze the bubbles to the inside of the guide part, and rise to the ground surface along the guide part.
[0007] Furthermore, the tooth height of the gap-filling portion of the double-thread structure is 3 to 6 mm, and the tooth angle is 60°.
[0008] Furthermore, the filling gap part with a double-thread structure is divided into a flow increasing part, a flow expanding part and a sealing top part from the bottom to the top of the tubular soil moisture sensor according to different thread pitches, and the tooth height of the filling gap part with a double-thread structure gradually increases from the bottom to the top of the tubular soil moisture sensor.
[0009] Furthermore, the pitch of the double-thread structure of the flow increasing portion decreases evenly from the bottom to the top of the flow increasing portion using the lead of the double-thread structure as a unit, and the tooth height at the bottom of the flow increasing portion is the smallest.
[0010] Furthermore, the pitch of the double-thread structure of the flow expansion portion increases uniformly from the bottom to the top of the flow expansion portion using the lead of the double-thread structure as a unit.
[0011] Furthermore, the pitches of the double-thread structure of the capping portion are equal, and the tooth height at the top of the capping portion is the largest.
[0012] Furthermore, the guide portion is provided through the outer side of the tubular soil moisture sensor, and the guide portion can be designed as a trough body with a U-shaped or V-shaped cross section.
[0013] Furthermore, the guide portion is configured as a longitudinal guide groove with a width of 2 mm and a depth of 1.5 mm, and one guide groove is distributed at intervals of 120° with the axis of the tubular soil moisture sensor as the center.
[0014] Furthermore, the tubular soil moisture sensor and the gap-filling portion with a double-thread structure are made of stainless steel, and the surfaces of the tubular soil moisture sensor and the gap-filling portion are sprayed with a coating that is corrosion-resistant and reduces the friction coefficient.
[0015] Furthermore, the integrated data processing module is electrically connected to the tubular soil moisture sensor, an insect monitor is fixed on one side of the integrated data processing module through a connecting component, a seedling monitor is fixed on the other side of the insect monitor through a connecting component, a meteorological monitor is fixed on the top of the integrated data processing module, the insect monitor and the seedling monitor through a connecting component, and the insect monitor, the seedling monitor and the meteorological monitor are all electrically connected to the integrated data processing module.
[0016] The beneficial effects of the present invention are as follows: The agricultural four-condition integrated monitoring equipment described in the present invention adopts the collaborative work of a filling gap part and a guide part. When the filling gap part is rotated and pressed down, the double-line thread with a variable pitch design can form a pressure difference, guiding the mud to evenly fill the hole wall gap, reducing the formation of local air cavities, breaking bubbles and dispersing them into the guide part, and the guide part forms an axial exhaust channel. The filling gap part cooperates with the filling gap part to squeeze the bubbles to the inside of the guide part and guide them to rise to the ground surface. Driven by the pressure difference, the mud flows upward along the guide part groove, and the bubbles are squeezed to the top of the flow-increasing part and then discharged with the mud, so that the tubular soil moisture sensor is in closer contact with the soil layer, ensuring that the tubular soil moisture sensor accurately obtains soil layer moisture data, reducing the interference of air cavities and gaps on the measurement of the tubular soil moisture sensor, so that the measurement results can better reflect the real soil layer moisture conditions, and improve the reliability of soil layer moisture monitoring in agricultural production.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0021] Example: Figure 1 As shown, an integrated monitoring device for the four agricultural conditions is provided, wherein the integrated data processing module 4 is electrically connected to the tubular soil moisture sensor 5, an insect condition monitor 1 is fixed to one side of the integrated data processing module 4 through a connecting component, and a seedling condition monitor 2 is fixed to the other side of the insect condition monitor 1 through a connecting component, a meteorological monitor 3 is fixed to the top of the integrated data processing module 4, the insect condition monitor 1 and the seedling condition monitor 2 through a connecting component, and the insect condition monitor 1, the seedling condition monitor 2 and the meteorological monitor 3 are all electrically connected to the integrated data processing module 4.
[0022] In the existing technology, the insect monitor 1 uses insect monitoring lights or spore traps to trap pests, and combines AI recognition technology with the comprehensive data processing module 4 to automatically classify and count the types and densities of pests. The seedling monitor 2 supports timed shooting and video monitoring to provide data support for fertilization and thinning. It uses high-definition cameras + AI image recognition technology and cooperates with the comprehensive data processing module 4 to remotely track the growth status of crops (such as plant height, leaf color, leaf area index) to evaluate whether the growth is normal. The weather monitor 3 cooperates with the seedling monitor 2 through the weather station to monitor wind speed, wind direction, temperature, humidity, light, etc., and then feeds the data back to the comprehensive data processing module 4. The comprehensive data processing module 4 combines historical data to predict the outbreak trend of pests and diseases, and warns of natural disasters such as drought, floods, and frost.
[0023] like Figures 1 to 9As shown, an integrated monitoring device for the four agricultural conditions also includes a comprehensive data processing module 4, a tubular soil moisture sensor 5, a filling gap portion 6 and a guide portion 7; the filling gap portion 6 is arranged on the outside of the tubular soil moisture sensor 5, and is assembled to change the flow direction of the mud 10 by changing the direction of the mud flow channel when the tubular soil moisture sensor 5 is rotated and inserted, and at the same time change the flow rate of the mud 10 by changing the area of the mud flow channel 10, thereby shearing and destroying the gaps and bubbles on the surface of the tubular soil moisture sensor 5 along the axial direction of the tubular soil moisture sensor 5 toward the surface; the guide portion 7 is located on the inner side of the filling gap portion 6, forming an axial exhaust channel running through the bottom of the hole, and when the tubular soil moisture sensor 5 is rotated and pressed down, the bubbles are squeezed to the inner side of the guide portion 7 by the mud 10 guided by the filling gap portion 6, and rise to the surface along the guide portion 7.
[0024] In this embodiment, the tubular soil moisture sensor 5 is a device that uses time-domain or frequency-domain reflectometry technology to monitor the moisture content of different soil layers in real time. It can accurately convert the soil dielectric constant into volumetric moisture content (within an error of ±2%), support dynamic monitoring for months to years, and achieve stable measurement in complex soils. Its core function is to provide layered real-time data for precision agricultural irrigation, water conservancy project infiltration warnings, and eco-hydrological research. Through automated and continuous monitoring, it significantly improves the efficiency of soil moisture assessment and the accuracy of decision-making. Before installing the tubular soil moisture sensor 5, the staff needs to use a special soil drill to drill a fixing hole 8 inside the soil layer 9. The radius of the fixing hole 8 is 5mm larger than the radius of the tubular soil moisture sensor 5, and the depth of the fixing hole 8 is consistent with the calibration depth of the tubular soil moisture sensor 5. Then, inject mud 10 to 1 / 2 the height of the hole. {If the soil layer 9 is sandy, the mud 10 should have a high viscosity (500-800cps); if the soil layer 9 is clay, the mud 10 should have a low viscosity (200-400cps); if the soil layer 9 is loam, the mud 10 should have a moderate viscosity (300-600cps)} and Matching the rotation speed (sand: 8-12rpm, loam: 5-8rpm, clay: 3-5rpm) combined with the soil type dynamically adjusts the parameters to improve the contact uniformity between the sensor and the soil, ensure measurement accuracy to optimize shear efficiency, and thus avoid settlement stratification caused by excessive thinning. In this embodiment, loam is taken from the soil layer 9, and then the tubular soil moisture sensor 5 is placed on the top of the fixing hole 8. The staff manually presses down the tubular soil moisture sensor 5 at a low and uniform speed of 8r / min (pressing speed <5cm / s) until the tubular soil moisture sensor 5 is fully inserted.
[0025] Specifically, the gap filling portion 6 is a double-thread structure as a whole and is fixed to the outside of the tubular soil moisture sensor 5. The tooth height of the double-thread structure is 3 to 6 mm, and the tooth angle is 60°.
[0026] In this embodiment, the tooth height of the end of the filling gap portion 6 with a double-thread structure close to the bottom of the tubular soil moisture sensor 5 is 3 mm, and the tooth height of the end of the filling gap portion 6 with a double-thread structure close to the top of the tubular soil moisture sensor 5 is 6 mm. The 60° obtuse-angle tooth profile reduces damage to the structure of the soil layer 9 and avoids the formation of local gaps. The double-thread structure forms a dual-channel mud flow when rotated and pressed down, thereby improving the bubble removal efficiency.
[0027] Specifically, the filling gap portion 6 with a double-thread structure is divided into a flow increasing portion 61, a flow expanding portion 62 and a sealing top portion 63 from the bottom to the top of the tubular soil moisture sensor 5 according to different thread pitches, and the tooth height of the filling gap portion 6 with a double-thread structure gradually increases from the bottom to the top of the tubular soil moisture sensor 5.
[0028] In this embodiment, the double-thread structure can push the mud 10 to flow upward along the guide groove. The close pitch section applies shear force to the mud 10 to break up bubbles. The variable pitch design guides the mud 10 to evenly fill the hole wall gap through the pressure difference. The tooth height of the gap filling part 6 with a double-thread structure gradually changes (3-6mm) to form a gradient mud 10 shear layer, which destroys the surface tension of the bubbles and makes the tiny bubbles merge into a larger volume, making them easier to be captured by the guide part 7.
[0029] Specifically, the pitch of the double-thread structure of the flow increaser 61 decreases uniformly from the bottom to the top of the flow increaser 61 using the lead of the double-thread structure as a unit, and the tooth height of the double-thread structure at the bottom of the flow increaser 61 is the smallest.
[0030] In this embodiment, the pitch of the double-thread structure of the flow-increasing portion 61 adopts a tapered pitch of 15mm→8mm. The pitch of the variable-pitch double-thread structure gradually decreases along the axial direction to form a stepped sealed cavity. As the tubular soil moisture sensor 5 drives the double-thread structure to rotate, the volume of each sealed cavity is compressed, resulting in a dynamic pressure difference in the axial direction of the fluid mud 10. After the mud 10 is compressed inside the sealed cavity, the pressure increases. At the same time, the mud 10 is squeezed by the bottom of the tubular soil moisture sensor 5 at the bottom of the fixing hole 8, thereby pushing the mud 10 to the lower part. The mud 10 flows in the pressure area (the top of the fixed hole 8). At the same time, the density of the double-thread structure of the flow-increasing part 61 increases. When the tubular soil moisture sensor 5 rotates, the double-thread structure of the flow-increasing part 61 increases the shear frequency of the mud 10. The high-frequency shear force accelerates the breakup and dispersion of bubbles in the mud 10, which is similar to the mechanical breakup of bubbles in the liquid by a stirrer, prompting the particles in the mud 10 to be evenly dispersed, forcing the mud 10 to fill the micro-gap between the hole wall and the sensor. At the same time, the bubbles are broken or entrained due to the shear action, reducing the formation of local air cavities.
[0031] Specifically, the pitch of the double-thread structure of the flow expansion portion 62 increases uniformly from the bottom to the top of the flow expansion portion 62 using the lead of the double-thread structure as a unit.
[0032] In this embodiment, the pitch of the double-thread structure of the flow expansion portion 62 adopts a tapered pitch of 8mm→15mm, and the pitch of the variable-pitch thread gradually increases along the axial direction to form a stepped sealing cavity. As the thread rotates, the volume of each sealing cavity expands, resulting in a dynamic pressure difference in the axial direction of the fluid mud 10. Since the flow increasing portion 61 increases the pressure at the connection with the flow expansion portion 62, and the flow expansion portion 62 reduces the pressure at the top of the flow increasing portion 61, the mud 10 is pushed to flow toward the sealing top portion 63.
[0033] Specifically, the pitches of the double-thread structure of the capping portion 63 are equal, and the tooth height at the top of the capping portion 63 is the largest.
[0034] In this embodiment, the double-thread structure of the top cap 63 provides a larger slurry holding space, which can accommodate the backflow caused by the solidification and shrinkage of the mud 10 and avoid the formation of a cavity at the top.
[0035] Specifically, the guide portion 7 is provided through the outer side of the tubular soil moisture sensor 5 , and the guide portion 7 can be designed as a trough body with a U-shaped or V-shaped cross section.
[0036] In this embodiment, the axial pressure gradient generated by the variable pitch double-thread structure cooperates with the flow channel of the guide part 7 to form a composite pressure field. Driven by the pressure difference, the mud 10 flows upward along the groove of the guide part 7. The bubbles are squeezed to the top of the flow increasing part 61 due to the density difference, and then discharged along the groove of the guide part 7 with the mud 10.
[0037] Specifically, the guide portion 7 is configured as a longitudinal guide groove with a width of 2 mm and a depth of 1.5 mm, and one guide groove is distributed at intervals of 120° with the axis of the tubular soil moisture sensor 5 as the center.
[0038] In this embodiment, the geometric shape of the guide portion 7 (such as the depth, width, and cross-sectional shape of the guide portion 7) can optimize the flow velocity distribution, ensure that the mud 10 rises along a spiral path, avoid lateral splashing, and thus suppress bubble accumulation. The guide portion 7 is provided every 120°, covering a 360° circumferential range of the tubular soil moisture sensor 5, ensuring that no matter where the bubble is located in the hole, it can enter the nearest guide portion 7; The guide portion 7 is longitudinally opened along the bottom of the double-thread structure teeth, forming a straight channel running from the top to the bottom of the sensor, providing a clear upward escape path for bubbles. When bubbles naturally float up in the mud 10 due to density differences, they are preferentially confined in the guide groove, avoiding bubble stagnation caused by the complex structure of the double-thread structure gap. During the rotational insertion of the tubular soil moisture sensor 5, the guide part 7 cooperates with the double-line spiral channel of the filling gap part 6 to form a "spiral + axial" composite flow path, which improves the filling efficiency of the mud 10. The spiral propulsion action of the double-line thread structure causes the mud 10 to generate vortexes, and the guide groove and the double-line thread structure form a spiral centrifugal force field, so that the mud 10 penetrates outward while the bubbles are thrown to the bottom of the teeth of the double-line thread structure and rise axially along the guide part 7, forcing the bubbles to gather at the bottom of the teeth, and the axial opening of the guide part 7 provides a directional outlet for the bubbles.
[0039] Specifically, the tubular soil moisture sensor 5 and the filling gap part 6 with a double-threaded structure are made of 304 stainless steel, and the surface of the tubular soil moisture sensor 5 and the filling gap part 6 with a double-threaded structure is sprayed with a corrosion-resistant and friction-reducing coating, which can effectively isolate the influence of the metal material of the equipment itself on the detection results.
