Description

Technical Field

[0001] This invention relates to the field of geographical teaching experimental observation technology, specifically to solar term and agricultural timing observation equipment. Background Technology

[0002] In the fields of agricultural geography teaching, seasonal agricultural research, and modern agricultural observation, long-term, continuous, and unmanned in-situ observation of crops in specific regions is crucial. Traditional observation methods mainly rely on manual labor to periodically go to the fields to record, photograph, and sample. This method is not only inefficient and labor-intensive, but also cannot obtain continuous and real-time data, making it easy to miss subtle growth changes and environmental responses of crops at key seasonal points.

[0003] Existing automated observation equipment, such as fixed surveillance cameras or simple sensor stations, while partially solving the problem of unattended operation, often has relatively limited functionality and its design does not fully consider the multiple challenges posed by complex field environments. These devices are typically exposed to the natural environment, and their observation results and data integrity are severely affected by various factors.

[0004] Specifically, the manifestations are as follows: Observational data is susceptible to environmental interference, compromising continuity and clarity: Existing equipment is easily obstructed or wetted in severe weather conditions such as rain, snow, and hail, leading to blurred images or even equipment damage and data interruptions. Furthermore, birds, insects, and other small animals perching or moving around on the equipment can severely obstruct the line of sight, generating numerous invalid data fragments. This makes obtaining a complete, clear, and continuous growth image spanning different seasons and weather conditions extremely difficult.

[0005] The equipment suffers from insufficient stability and reliability in complex environments: especially during irrigation or the rainy season, when the soil becomes soft and muddy, traditional methods of fixing with ground stakes or heavy objects can easily cause the equipment to sink, tilt, or even topple. This instability directly leads to changes in the observation perspective, invalid data comparisons, and even equipment damage, failing to meet the rigid requirements of long-term, fixed-point observation.

[0006] Lack of multi-factor collaborative observation capabilities: Crop growth is the result of the combined effects of multiple factors such as light, temperature, and water. However, traditional observation equipment focuses primarily on image capture, lacking synchronous and precise monitoring of key environmental factors (such as field water level / soil moisture). This makes it difficult to accurately correlate crop growth with hydrological conditions during teaching and research, significantly diminishing the value of the data.

[0007] The equipment itself has a disturbance effect and limited protection capabilities: its obtrusive appearance and operating noise can easily disturb surrounding wildlife, causing them to change their natural behavior and resulting in observations that do not reflect the true ecological environment. Furthermore, most equipment has limited waterproof and dustproof ratings, and its internal precision components face a high risk of failure when facing rising water levels or extreme weather.

[0019] The beneficial effects of this invention are: 1. This solar term agricultural planting observation device, through the setting of the observation components, ensures the continuity and clarity of high-definition observation: Intelligent shading mechanism: It can automatically deploy in rain, snow, hail and other weather conditions to protect the front of the observation window glass and ensure that clear images can still be obtained in severe weather.

[0020] Intelligent deterrence function: Uses microcurrents and ultrasound to deter birds, insects, and other small animals, preventing them from obstructing the lens or damaging the equipment. This minimizes environmental interference, ensuring the continuity, integrity, and high quality of the acquired crop growth images, providing a reliable data foundation for analyzing the continuous impact of seasonal changes on crops.

[0021] Enhance stability and reliability in complex environments: Multiple anchoring system: Initial fixation is achieved through the auger drill rod of the positioning mechanism; when the water level rises and the soil loosens, the stabilizing mechanism can be automatically triggered, using the inverted claw structure to penetrate deeper into a more stable soil layer and provide secondary anchoring.

[0022] Teaching significance: It ensures that the equipment will not tilt or collapse in wet and soft environments such as during the rainy season and after irrigation, ensuring the accuracy and comparability of long-term observation data, and enabling students to reliably study the impact of changes in water conditions on crops.

[0023] To achieve simultaneous and accurate monitoring of hydrological elements: The water level monitoring rod is equipped with multiple probes arranged vertically, which can accurately monitor the vertical changes in field water level or soil moisture content.

[0024] Teaching significance: By synchronously observing the two key geographical elements of "crop growth" and "water conditions", students can intuitively analyze the intrinsic relationship between precipitation, irrigation seasons and agricultural timing, farmland hydrology and crop growth, and deepen their understanding of the "water" element in agricultural geography.

[0025] It has intelligent protection and concealment functions: Automatic sealing and airbag waterproofing: The cover automatically closes and inflates to seal in dangerous water levels, protecting the internal precision electronic equipment.

[0026] Camouflage coating: Reduces the disturbance of equipment to wild animals, makes the equipment more concealed, reduces the risk of human damage or theft, and makes the observed behavior of animals and plants more natural and realistic.

[0027] Pedagogical significance: It ensures the equipment's survivability in unattended field environments, guarantees the sustainability of long-term observation projects, and accumulates valuable long-term sequence data for teaching.

[0028] By combining irregularly shaped grooves with irregularly shaped pressure blocks and spring-loaded contact switches, the opening and closing of the cover, status sensing, and waterproofing triggering are linked, achieving a high level of automation and reducing the need for manual intervention.

[0029] Pedagogical significance: As a complex systems engineering example, it can serve as a teaching model for students to understand how mechanical structures, automatic control, and environmental perception work together.

[0030] 2. This solar term agricultural planting observation equipment, through the setting of aircraft components, realizes the aerial mobile transmission of energy and materials: The drone can fly freely between the base and the observation point, efficiently transmitting power and solving the power supply problem caused by the dispersed layout of observation components.

[0031] Teaching significance: This lesson demonstrates the practical application of drone technology in modern geographic information systems, remote sensing, and field surveys, allowing students to experience how cutting-edge technologies can improve the efficiency and scope of geographical research.

[0032] Innovative collection of multi-dimensional environmental information: Gas collection mechanism: It can collect specific scents produced by different solar terms, different plant flowering periods, or special periods and store them in a gas collection bag.

[0033] Enriching the sensory dimensions of teaching: Geographical environments are not only visual but also multi-sensory experiences that include elements such as smell. Bringing the "smell of the fields" directly into the classroom can greatly enhance the authenticity and immersion of teaching, helping students build a more comprehensive and profound memory and understanding of specific ecological environments, such as rice paddies, flower fields, and forests.

[0034] Interdisciplinary connections: It perfectly connects plant phenology and volatiles in geography and biology, and can be used to study the relationship between plants and the environment. It is an excellent vehicle for carrying out interdisciplinary project-based learning.

[0035] Enhance the flexibility and coverage of the observation system: Unmanned aerial vehicles (UAVs) are not limited by terrain and can easily reach areas inaccessible to personnel to deploy or maintain observation equipment, enabling simultaneous observation of various microenvironments such as hillsides, depressions, and the edges of water bodies. This makes it possible to conduct comparative studies on the differences in crop growth under different microclimates and microenvironments, helping students to deeply understand the geographical principle of "adapting to local conditions" and cultivate their geographical practical skills.

[0036] 3. This solar term agricultural planting observation equipment, through the setting of the base component, serves as the ground energy center and basic observation station of the system, realizing energy self-sufficiency and green teaching demonstration: integrating photovoltaic panels and micro wind turbines, it can directly utilize the natural sunlight and wind energy of the observation site to generate electricity, and store it in the central energy storage battery through inverters and rectifiers.

[0037] Pedagogical significance: It provides students with vivid examples of renewable energy technologies applied to field scientific observation, combining abstract physical and geographical knowledge with specific agricultural environmental monitoring, perfectly interpreting the concept of human-land harmony and sustainable development, and is of great educational significance.

[0038] Provides a stable multi-source energy supply: As a fixed energy base, it can charge the intermediate energy storage batteries of the aircraft components through the power supply connector, ensuring the long-term operation of the entire observation system and solving the problem of power supply difficulties for field equipment.

[0039] Teaching significance: To ensure the continuity and stability of observation activities, avoid interruption of teaching observation data due to equipment power failure, and ensure the continuity of geography observation courses.

[0040] Integrated and intuitive teaching tool for solar terms: Sundial mechanism: Visualizing the changes of solar terms: 48 lights correspond to the time periods with sunshine throughout the day. Through the changes in the lights on / off caused by the shadow of the pointer, the traditional concept of relying on the capture of the light and shadow of the pointer is transformed into a light signal that can be seen by the naked eye. It shows the correspondence between the sun's position and time during the day, as well as the correspondence between the sun's position and time at the same time during the day at different solar terms.

[0041] Stimulating learning interest: The dynamically changing colors of the lights attract students' attention, combining ancient wisdom with modern technology, enhancing the fun and interactivity of geographical observation, and making it an ideal teaching tool for teaching astronomy, calendar, and solar terms.

[0042] It possesses environmental adaptability and stability: The bottom is equipped with a seismic isolation bearing and a base, which can adapt to uneven outdoor ground, reduce vibration interference, ensure its own stability, and provide reliable ground support for the entire system.

[0059] The 3025 intelligent deterrence pad uses microcurrents and ultrasound to repel birds, insects, and other small animals, preventing them from obstructing the lens or damaging the equipment. This minimizes environmental interference, ensuring the continuity, integrity, and high quality of acquired crop growth images, providing a reliable data foundation for analyzing the continuous impact of seasonal changes on crops.

[0060] Enhance stability and reliability in complex environments: Multiple anchoring system: Initial fixation is achieved through the auger drill rod of the positioning mechanism 305; when the water level rises and the soil loosens, the stabilizing mechanism 303 can be automatically triggered, using the inverted claw 3033c structure to penetrate into a more stable soil layer and provide secondary anchoring.

[0061] Teaching significance: It ensures that the equipment will not tilt or collapse in wet and soft environments such as during the rainy season and after irrigation, ensuring the accuracy and comparability of long-term observation data, and enabling students to reliably study the impact of changes in water conditions on crops.

[0062] To achieve simultaneous and accurate monitoring of hydrological elements: The 304 water level monitoring rod has multiple probes arranged vertically, which can accurately monitor the vertical changes in field water level or soil moisture content.

[0063] Teaching significance: By synchronously observing the two key geographical elements of "crop growth" and "water conditions", students can intuitively analyze the intrinsic relationship between precipitation, irrigation seasons and agricultural timing, farmland hydrology and crop growth, and deepen their understanding of the "water" element in agricultural geography.

[0064] It has intelligent protection and concealment functions: Automatic sealing and airbag waterproofing 3014: Automatically closes the cover and inflates to seal in dangerous water levels, protecting internal precision electronic equipment.

[0065] Camouflage coating: Reduces the disturbance of equipment to wild animals, makes the equipment more concealed, reduces the risk of human damage or theft, and makes the observed behavior of animals and plants more natural and realistic.

[0066] Pedagogical significance: It ensures the equipment's survivability in unattended field environments, guarantees the sustainability of long-term observation projects, and accumulates valuable long-term sequence data for teaching.

[0067] By combining the irregular groove 3026 with the irregular pressure block and spring-loaded contact switch, the opening and closing of the cover, status sensing and waterproof triggering are linked, achieving a high level of automation and reducing the need for manual intervention.

[0068] Pedagogical significance: As a complex systems engineering example, it can serve as a teaching model for students to understand how mechanical structures, automatic control, and environmental perception work together.

[0069] Example 2; In this embodiment, the airborne transport of energy and materials is achieved through the configuration of aircraft component 2: The drone can fly freely between the base and the observation point, efficiently completing the power transmission and solving the power supply problem caused by the dispersed arrangement of the observation components 3.

[0070] Teaching significance: This lesson demonstrates the practical application of drone technology in modern geographic information systems, remote sensing, and field surveys, allowing students to experience how cutting-edge technologies can improve the efficiency and scope of geographical research.

[0071] Innovative collection of multi-dimensional environmental information: Gas collection mechanism 203: It can collect specific scents produced by different solar terms, different plant flowering periods, or special periods and store them in the gas collection bag 2033.

[0072] Enriching the sensory dimensions of teaching: Geographical environments are not only visual but also multi-sensory experiences that include elements such as smell. Bringing the "smell of the fields" directly into the classroom can greatly enhance the authenticity and immersion of teaching, helping students build a more comprehensive and profound memory and understanding of specific ecological environments, such as rice paddies, flower fields, and forests.

[0073] Interdisciplinary connections: It perfectly connects plant phenology and volatiles in geography and biology, and can be used to study the relationship between plants and the environment. It is an excellent vehicle for carrying out interdisciplinary project-based learning.

[0074] Enhance the flexibility and coverage of the observation system: Unmanned aerial vehicles (UAVs) are not limited by terrain and can easily reach areas inaccessible to personnel to deploy or maintain observation equipment, enabling simultaneous observation of various microenvironments such as hillsides, depressions, and the edges of water bodies. This makes it possible to conduct comparative studies on the differences in crop growth under different microclimates and microenvironments, helping students to deeply understand the geographical principle of "adapting to local conditions" and cultivate their geographical practical skills.

[0075] Example 3; In this embodiment, the base component 1 serves as the ground energy center and basic observation station of the system, realizing energy self-sufficiency and green teaching demonstration: integrating photovoltaic panels 104 and micro wind turbines 106, it can directly utilize the natural sunlight and wind energy of the observation site to generate electricity, and store it in the central energy storage battery through inverters and rectifiers.

[0076] Pedagogical significance: It provides students with vivid examples of the application of renewable energy technologies such as solar and wind power in field scientific observation, combining abstract physical and geographical knowledge with specific agricultural environmental monitoring, perfectly interpreting the concept of human-land harmony and sustainable development, and is of great educational significance.

[0077] Provides a stable multi-source energy supply: As a fixed energy base, the intermediate energy storage battery 202 of the aircraft component 2 can be charged through the power supply connector 108, ensuring the long-term operation of the entire observation system and solving the problem of power supply difficulties for field equipment.

[0078] Teaching significance: To ensure the continuity and stability of observation activities, avoid interruption of teaching observation data due to equipment power failure, and ensure the continuity of geography observation courses.

[0079] The integrated and intuitive teaching tool for solar terms, the sundial mechanism 105, visualizes the changes in solar terms: 48 lights correspond to the time periods with sunshine throughout the day. Through the changes in the lights on / off caused by the shadow of the pointer, the traditional concept of relying on capturing the light and shadow of the pointer 1051 is transformed into a light signal that can be seen with the naked eye. It shows the correspondence between the sun's position and time during the day, as well as the correspondence between the sun's position and time at the same time during the day at different solar terms.

[0080] Stimulating learning interest: The dynamically changing colors of the lights attract students' attention, combining ancient wisdom with modern technology, enhancing the fun and interactivity of geographical observation, and making it an ideal teaching tool for teaching astronomy, calendar, and solar terms.

[0081] It possesses environmental adaptability and stability: The bottom is equipped with a seismic isolation bearing 102 and a base 103, which can adapt to uneven outdoor ground, reduce vibration interference, ensure its own stability, and provide reliable ground support for the entire system.

[0082] To facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process will be described in detail below.

[0083] In practical applications, during use: Observation Component 3: Based on the teaching observation needs, a suitable location for agricultural planting observation is selected to meet the observation requirements of different micro-environments. After placing Observation Component 3 on the ground at the selected location, the rotary motor 3054 is started and controlled to drive the rotary gear 3053 to rotate, which in turn drives the positioning rod 3051 to rotate. The threaded groove at the bottom of the positioning rod 3051 assists in drilling into the ground and extending into the soil. When all four positioning rods 3051 are in the soil, the position of the component is fixed. The opening and closing control motor 3027 is started and controlled to drive the double gear to rotate. The double gear meshes with the inner fixed tooth plate 3011d, which moves backward to open the main cover 3011a. The side rotary control motor 307 is then controlled to rotate outward to open the sealing cover 306, activating the high-definition monitoring probe in the observation box 3022 for real-time observation and monitoring. When the high-definition monitoring... When the probe detects a small animal loitering in front, affecting the high-definition monitoring probe's observations, the microcurrent stimulation circuit and miniature ultrasonic repellent on the deflector pad 3025 are controlled to deliver a microcurrent electric shock or ultrasonic wave, forcing the small animal to leave. This minimizes the impact on the observation equipment from animals or insects in the surrounding natural environment. When rain, snow, or hail falls, affecting the high-definition monitoring probe's observations, the gravity sensor 2023 on the edge of the glass front barrier 3024 senses the falling rain, snow, or hail and controls the retractor 3012a to release a pull rope outwards. Under the action of the long spring cylinder 3013a, the shielding mechanism 3012 slides outwards rapidly. At the same time, the folding baffle 3012b opens and is positioned above the observation box 3022, shielding the observation box 3022 and ensuring a clear observation effect for the high-definition monitoring probe inside. When the observed location experiences continuous rainfall or a rise in water level, the soil may become soaked, causing the connection between the positioning rod 3051 and the soil to loosen. At this time, the water level monitoring probe on the water level monitoring rod 304, immersed in water, sequentially monitors the water pressure, thus sensing a rise in water level. Simultaneously, the hydraulic cylinder 3032b retracts, pulling the rod out of the insertion hole. Under the action of the pressure spring 3034, the stabilizing head 3033 rapidly moves downwards until it inserts into the soil. Once inside, the stabilizing head 3033 is compressed by the soil, causing the claw 3033c to retract towards the downward insertion rod 3033a, thus fixing the hook 3033b and the movable... When the locking relationship between the movable hooks 3033d and the inverted claw 3033c is released, the movable hook 3033d falls naturally under the action of gravity. At this time, the return spring 3033e exerts outward pressure on the inverted claw 3033c, causing the inverted claw 3033c to contact the soil at its maximum rotation stroke, thereby increasing the gripping force in the soil. This increases the gripping performance of the observation component in rainy weather, improves stability, and ensures the effective observation time and good observation state of the observation component. It also aims to meet the monitoring and observation of the growth status of crops in different solar terms during the twenty-four solar terms, supplement the geographical teaching knowledge, and more intuitively apply the real observation results in the external environment directly to classroom teaching. When the water level monitoring probes at different heights on the water level monitoring rod 304 sense a continuous rise in water level, reaching the danger threshold, the side-rotation control motor 307 rotates the sealing cover plate 306 upwards, and controls the opening and closing control motor 3027 to drive the double gear to rotate. The double gear engages with the inner fixed toothed plate 3011d, thereby moving forward to close the main cover 3011a. The main cover 3011a and the sealing cover plate 306 merge to form a closed space. During this process, the sliding plate 3011e inside the main cover 3011a moves forward. When the irregularly shaped pressure block slides to... At the irregular groove 3026, under the action of the spring, the irregular pressure block falls into the irregular groove 3026 and triggers the spring-loaded contact switch in the irregular groove 3026, opening the airbag 3014 on the main cover 3011a and the sealing cover 306. The airbag 3014 increases the airtightness between the main cover 3011a and the sealing cover 306, improving the waterproofness of the observation component. The camouflage pattern coating on the outside of the observation box 3022 and the main cover 3011a facilitates the concealment and recording of a more realistic natural environment while reducing fright and disturbance to animals. Base component 1: The photovoltaic panel 104 absorbs and converts light energy into electrical energy, which is then transformed and rectified by an inverter and rectifier, and finally stored in the central energy storage battery for use by the aircraft component 2 and the observation component 3. The micro wind turbine 106 has a similar function. It absorbs wind energy and converts it into electrical energy, which is then transformed and rectified by an inverter and rectifier, and finally stored in the central energy storage battery. By controlling the use of the directional motor 107, the direction of use of the micro wind turbine 106 can be adjusted according to the wind direction in the natural environment to achieve the best use effect of the micro wind turbine 106. The use of the sundial mechanism 105: When sunlight shines on it, the 48 color-changing lamps 1054 on the disc 1052 absorb and convert energy through the micro photovoltaic panels and power conversion elements, thus providing energy for the color-changing lamp beads, causing them to light up and change color continuously. The color-changing lamp 1054 that is blocked by the pointer 1051 cannot convert and utilize light energy and appears to be off, making the entire observation process more intuitive. The setting of 48 color-changing lamps 1054 can be used to compare and represent the time periods with sunlight throughout the day. Aircraft Component 2: The UAV main body 201 is set up to dock with the base component 1 and the observation component 3, and is used for energy transfer between the base component 1 and the observation component 3. The energy in the central energy storage battery is stored through the intermediate energy storage battery 202, and then moved to the location by the UAV main body 201 and delivered to the mobile power box 3011c to ensure the energy endurance for normal observation. If the electrical energy converted and stored in the central energy storage battery is insufficient, the UAV main body 201 can also fly to the nearest power station for replenishment. The gas collection mechanism 203 is designed so that, as the twenty-four solar terms change, different plants gradually grow to their peak flowering period or special periods, producing special odors. When the main body of the drone 201 approaches the plant, the micro blower 2032 is activated to blow the special odors from nature into the gas collection bag 2033 for absorption and storage. This allows for the capture of special odors from nature, which are then transferred to the teaching department to supplement the teaching of geography-related content, making the teaching content more intuitive.

[0084] In summary, by utilizing the above-mentioned technical solution of this invention, the solar term agricultural planting observation equipment, through the setting of observation component 3, ensures the continuity and clarity of high-definition observation: Intelligent shielding mechanism 3012: automatically deploys in rain, snow, or hail to protect the front glass of the observation window 3024, ensuring clear images can still be obtained even in adverse weather conditions. Intelligent deterrent function deterrent pad 3025: uses microcurrents and ultrasonic waves to deter birds, insects, and other small animals, preventing them from obstructing the lens or damaging the equipment. This minimizes environmental interference factors, ensuring the continuity, integrity, and high quality of the acquired crop growth image data, providing a reliable data foundation for analyzing the continuous impact of solar term changes on crops. Enhanced stability and reliability in complex environments: Multiple anchoring system: initial fixation is achieved through the spiral drill rod of positioning mechanism 305; when the water level rises or the soil loosens, stabilizing mechanism 303 can be automatically triggered, using the inverted claw 3033c structure to penetrate deeper into a more stable soil layer, providing secondary anchoring. Teaching Significance: The equipment is designed to remain stable and prevent tilting or collapse in wet, soft environments such as during the rainy season and after irrigation, ensuring the accuracy and comparability of long-term observation data. This allows students to reliably study the impact of changing water conditions on crops. Synchronous and Precise Monitoring of Hydrological Elements: The 304 water level monitoring rod features multiple vertically arranged probes, enabling precise monitoring of vertical changes in field water levels or soil moisture content. Teaching Significance: Synchronizing the observation of the two key geographical elements, "crop growth" and "water conditions," allows students to intuitively analyze the intrinsic connections between precipitation, irrigation seasons, agricultural timing, farmland hydrology, and crop growth, deepening their understanding of the "water" element in agricultural geography. Intelligent Protection and Concealment Functions: Automatic sealing and airbag waterproofing (3014): The cover automatically closes and inflates to seal at dangerous water levels, protecting the internal precision electronic equipment. Camouflage Coating: Reduces disturbance to wild animals, enhances equipment concealment, minimizes the risk of vandalism or theft, and makes observed plant and animal behavior more natural and realistic. Teaching Significance: It ensures the equipment's survivability in unattended field environments, guarantees the sustainability of long-term observation projects, and accumulates valuable long-term sequence data for teaching. Through the cooperation of the irregularly shaped groove 3026 with the irregularly shaped pressure block and spring-loaded contact switch, it achieves the linkage between cover opening and closing, status sensing, and waterproof triggering, resulting in a high level of automation and reducing the need for manual intervention. Teaching Significance: As a complex systems engineering example, it can serve as a teaching model for students to understand how mechanical structures, automatic control, and environmental perception work together. The setup of aircraft component 2 enables the aerial transport of energy and materials: the UAV can fly freely between the base and the observation point, efficiently completing the power transmission and solving the power supply problem caused by the dispersed layout of observation component 3. Teaching Significance: It demonstrates the practical application of UAV technology in modern geographic information systems, remote sensing, and field surveys, allowing students to experience how cutting-edge technology can improve the efficiency and scope of geographical research.Innovative Collection of Multi-Dimensional Environmental Information: The gas collection mechanism 203 collects specific odors produced during different solar terms, plant flowering periods, or special times, and stores them in the gas collection bag 2033. Enriching Sensory Teaching Dimensions: The geographical environment is not only visual but also a multi-sensory experience encompassing elements such as smell. Bringing the "smell of the fields" directly into the classroom greatly enhances the realism and immersion of teaching, helping students build a more comprehensive and profound memory and understanding of specific ecological environments, such as rice paddies, flower fields, and forests. Interdisciplinary Connections: It perfectly connects plant phenology and volatiles in geography and biology, and can be used to study the interaction between plants and the environment, serving as an excellent vehicle for interdisciplinary project-based learning. Enhancing the Flexibility and Coverage of the Observation System: Unmanned aerial vehicles (UAVs) are not limited by terrain and can easily reach areas inaccessible to personnel to deploy or maintain observation equipment, enabling simultaneous observation of various microenvironments, such as hillsides, depressions, and water edges. This makes it possible to compare and study the differences in crop growth under different microclimates and environments, helping students deeply understand the geographical principle of "adapting to local conditions" and cultivate their geographical practical skills. Through the setup of base component 1, which serves as the system's ground energy center and basic observation station, energy self-sufficiency and green teaching demonstration are achieved: integrating photovoltaic panels 104 and micro-wind turbines 106, it can directly utilize natural sunlight and wind power from the observation site to generate electricity, which is then stored in the central energy storage battery through inverters and rectifiers. Educational significance: It provides students with vivid examples of renewable energy technologies such as solar and wind power applied to field scientific observation, combining abstract physical and geographical knowledge with specific agricultural environmental monitoring, perfectly interpreting the concept of human-land harmony and sustainable development, and is highly educational. It provides stable multi-source energy supply: As a fixed energy base, it can charge the intermediate energy storage battery 202 of the aircraft component 2 through the charging connector 108, ensuring the long-term operation of the entire observation system and solving the problem of power supply difficulties for field equipment. Educational significance: It ensures the continuity and stability of observation activities, avoids interruption of teaching observation data due to equipment power failure, and guarantees the continuity of geographical observation courses. The integrated and intuitive sundial mechanism 105 is a key teaching tool for understanding the solar terms and their corresponding time periods. It visualizes the changes in solar terms: 48 lights correspond to the periods of daylight, and the lighting changes caused by the pointer's shadow transform the traditional reliance on capturing the light and shadow of the pointer 1051 into a visible light signal. This visually demonstrates the correspondence between the sun's position and time throughout the day, as well as the correspondence between the sun's position and time at the same time during different solar terms. It also stimulates learning interest: the dynamically changing colors attract students' attention, combining ancient wisdom with modern technology to enhance the fun and interactivity of geographical observation, making it an ideal teaching tool for astronomy, calendar systems, and solar terms. Furthermore, it possesses environmental adaptability and stability: equipped with a vibration isolation support 102 and a base 103, it can adapt to uneven outdoor ground, reducing vibration interference and ensuring its own stability, providing reliable ground support for the entire system.
