[0002] Currently, micro-weather stations are widely used in complex field scenarios such as forest fire monitoring, soil moisture monitoring in mountainous farmland, desert ecological observation, micro-environmental monitoring of ancient buildings, early warning of geological disasters in mountainous areas, grassland desertification monitoring, environmental observation of outdoor photovoltaic and wind farm sites, environmental monitoring of wildlife habitats in forest areas, and micro-meteorological monitoring of power transmission towers in mountainous areas. These scenarios are often located in remote areas with insufficient power grid infrastructure coverage, making it impossible to deploy municipal power lines. Therefore, the meteorological monitoring system must rely on self-powered operation to achieve long-term unattended continuous operation. Summary of the Invention

[0047] To improve self-powering capability and structural integration, this application provides a power supply system for powering a meteorological sensor monitoring module. Additionally, this application also provides a meteorological monitoring system.

[0048] Figure 1 An exemplary schematic diagram of a meteorological monitoring system is shown. The meteorological monitoring system may include a meteorological sensor monitoring module 101 and any of the power supply systems provided in this application.

[0049] This application provides a power supply system. Please refer to the embodiments thereof. Figure 1 The power supply system may include a multi-source power generation module and a base 103. The meteorological sensor monitoring module 101 is disposed on top of the multiple power generation modules. An energy storage component is disposed inside the base 103, which is used to provide power to the meteorological sensor monitoring module 101.

[0050] The meteorological sensor monitoring module 101 can integrate high-precision temperature and humidity sensors, atmospheric pressure sensors, wind speed and direction acquisition modules, light sensors, and rainfall sensors, among other multi-dimensional monitoring probes. It can simultaneously collect core meteorological parameters such as ambient temperature, ambient humidity, atmospheric pressure, real-time wind speed, real-time wind direction, solar radiation intensity, and cumulative rainfall. It provides comprehensive monitoring dimensions, high acquisition accuracy, and fast response speed.

[0051] Optionally, the meteorological sensor monitoring module 101 adopts an integrated waterproof probe structure, and the shell is made of high-strength waterproof and flame-retardant engineering plastic material, which has the properties of high and low temperature resistance, aging resistance, corrosion resistance and rain and snow erosion resistance, which is conducive to stable operation when exposed to the outdoor atmospheric environment for a long time.

[0052] Figure 2 This is an exploded view of a multi-source power generation module. The multi-source power generation module includes: a flow guiding assembly 201, wind turbine blades 202, and a rotating shaft 203. The flow guiding assembly 201 includes a first fixing plate 2011, a second fixing plate 2012, and a plurality of thermoelectric generator plates 2013; the first fixing plate 2011 and the second fixing plate 2012 are arranged opposite to each other, the first end of the thermoelectric generator plate 2013 is connected to the first fixing plate 2011, and the second end of the thermoelectric generator plate 2013 is connected to the second fixing plate 2012; one end of the rotating shaft 203 is rotatably connected to the first fixing plate 2011, and the other end of the rotating shaft 203 passes through the second fixing plate 2012 and is connected to the base 103, wherein at least two wind turbine blades 202 are centrally symmetrically distributed along the rotating shaft 203 on the side; the plurality of thermoelectric generator plates 2013 are arranged circumferentially around the rotating shaft.

[0053] Optionally, the thermoelectric generator 2013 can be a bismuth telluride (Bi2Te3) based thermoelectric generator 2013.

[0054] In this embodiment, the flow guiding component 201 serves to fix and support the meteorological sensor monitoring module 101. The wind turbine blades 202 and the rotating shaft 203 are disposed inside the flow guiding component 201. The wind turbine blades 202 drive the rotating shaft 203 to rotate, thereby generating wind power. Furthermore, the support plate of the flow guiding component 201 is a thermoelectric generator plate 2013, which utilizes the temperature difference between its two surfaces to generate electricity. Therefore, the power supply system provided in this application can generate electricity using temperature differences or wind power, possessing the capability for multiple types of power generation.

[0055] The second fixing piece 2012 can be fixedly connected to the base 103. In some examples, the second fixing piece 2012 can be affixed to the base 103. In other examples, the base 103 may include a cover 1031 and a housing 1032. The second fixing piece 2012 may be implemented as the cover 1031 of the base 103.

[0056] In one possible implementation, the thermoelectric generator 2013 includes a flow guiding surface 2013A, which is the side of the thermoelectric generator 2013 facing away from the rotation axis 203.

[0057] The guide surface 2013A of the thermoelectric generator 2013 can directly receive solar radiation, absorbing heat and increasing its temperature. The guide surface 2013A is also the hot end of the thermoelectric generator 2013. While generating electricity, the wind turbine blades 202 continuously agitate the air inside the guide assembly 201, creating a continuous cooling airflow. This airflow can reach the surface of the thermoelectric generator 2013 facing the rotation axis 203, effectively cooling the cold end of the thermoelectric generator 2013. In this design, the hot end of the thermoelectric generator 2013 is heated by sunlight, while the cold end is continuously cooled by the airflow generated by the blades, effectively increasing the actual temperature difference between the hot and cold ends of the thermoelectric generator 2013, which is beneficial for improving the power generation efficiency of the thermoelectric generator 2013.

[0058] In this embodiment, the support plate in the flow guiding component 201 not only provides support but also functions as a thermoelectric generator. The surface of the thermoelectric generator plate 2013 facing away from the rotation axis 203 can serve as a flow guiding surface 2013A. The flow guiding surface 2013A can be used to guide external wind to the wind turbine blades 202, thereby improving the wind power generation effect. Therefore, the flow guiding component 201 in the power supply system has multiple functions, including fixed support, thermoelectric generator, and flow guiding, enabling the power supply system to have higher integration, a more compact structure, and fewer components.

[0059] In one possible design, the outer contour of the first fixing plate 2011 is circular, and the outer contour of the second fixing plate 2012 is also circular. This design allows the guide assembly 201 to be cylindrical and surround the outside of the wind turbine blade 202.

[0060] Optionally, both the first fixing plate 2011 and the second fixing plate 2012 can be made of PC composite material with high light transmittance, high heat absorption, and strong weather resistance. This design allows the heat-guiding component 201 to remain resistant to aging and deformation under long-term outdoor exposure, while maintaining stable heat absorption performance.

[0061] The airflow guiding component 201 can gather, rectify, and guide turbulent natural winds in the field, concentrating the dispersed and disordered airflow into the working area of ​​the wind turbine blade 202. This increases the airflow concentration and the blade's contact area, effectively improving wind energy utilization and wind power generation efficiency, enabling the thermoelectric generator structure to empower wind power generation. The airflow guiding surface 2013A of the thermoelectric generator plate 2013 in the airflow guiding component 201 is completely exposed to the external environment, continuously receiving solar radiation and accumulating heat to form a stable high-temperature hot end. The surface of the thermoelectric generator plate 2013 facing the rotation axis 203 can be referred to as the inner surface. One side of the inner surface of the thermoelectric generator plate 2013 is the cold end region. Forced air cooling is achieved through the continuous convective airflow generated by the wind turbine blades, continuously reducing the temperature of the inner surface of the thermoelectric generator plate 2013. Through the coupling of "external heat + internal cooling active heat dissipation," the temperature difference between the hot and cold ends is significantly increased. The current guiding component 201 in the power supply system provided in this application simultaneously realizes multiple functions such as wind power guidance, structural protection, and high-efficiency thermoelectric power generation. The various systems promote each other and enhance each other's efficiency. The overall performance is far superior to the individual superposition of each component, demonstrating outstanding creativity and practicality.

[0062] In some examples, the edge connecting the flow-guiding surface 2013A of the thermoelectric generator 2013 to the second fixing plate 2012 is denoted as the first edge. The second fixing plate 2012 can be implemented as a circular plate or an annular plate. Please refer to... Figure 3 The first side of the thermoelectric generator 2013 extends towards the outer contour of the second fixing plate 2012, intersecting the outer contour at point P. The tangent of the outer contour of the second fixing plate 2012 at point P forms an acute angle x with the first side, and the acute angle x can be any angle in the angle range [15°, 75°]. Optionally, in some application scenarios, the acute angle x can be 45°. The guide surface of the thermoelectric generator can fully deflect the airflow, forming a strong intracavity spiral flow inside the guide assembly without generating excessive flow separation, resulting in moderate wind resistance.

[0063] In one possible implementation, a power supply system based on any of the foregoing embodiments is used. The wind turbine blade is C-shaped; wherein the concave surface of the wind turbine blade 202 is the windward side, and the convex surface is the leeward side.

[0064] Each wind turbine blade 202 can be a curved blade. The wind turbine blade 202 is C-shaped. Compared with flat blades, the C-shaped wind turbine blade 202 has a stronger wind energy capture capability, does not require additional mechanical steering or wind alignment mechanisms, can eliminate complex moving parts, greatly simplify the overall mechanical structure of the turbine, and reduce the probability of failure in the field.

[0065] In some examples, the power supply system may include multiple wind turbine blades 202. For example, please combine... Figure 1 and Figure 4 When there are two wind turbine blades 202, the two wind turbine blades 202 are arranged on both sides of the rotating shaft 203, in a centrally symmetrical distribution, and the whole is S-shaped. The two wind turbine blades 202 can be integrally molded without splicing gaps. The two integrally molded wind turbine blades 202 can be referred to as a torsional drag blade structure. The main body of the two integrally molded wind turbine blades 202 can be made of high-strength ABS composite material, which has the advantages of high toughness, wind impact resistance, sand and dust wear resistance, and aging deformation resistance, and is suitable for extreme and harsh working conditions such as strong winds, rainstorms, and sandstorms in the field.

[0066] In other examples, the number of wind turbine blades 202 in the power supply system can be 2N, where N is a positive integer greater than 1. The 2N wind turbine blades 202 can be evenly distributed around the circumference of the rotation shaft 203, and their distribution is centrally symmetrical. Furthermore, the windward side of one blade is positioned on the leeward side of the other blade on the side facing any two adjacent wind turbine blades 202.

[0067] In one possible implementation, based on the power supply system provided in any of the foregoing embodiments, please refer to the combination of... Figure 2 The first fixing piece 2011 includes a limiting groove 2011A and a plurality of first through holes 2011B. The plurality of first through holes 2011B are arranged circumferentially around the limiting groove 2011A. One end of the rotating shaft 203 is rotatably connected to the limiting groove 2011A.

[0068] Optionally, the wind turbine blade 202 is C-shaped. Under light wind conditions in the field, the wind turbine blade 202 can quickly start rotating, and continuously agitate the air inside the guide assembly 201 through the curved torsion structure, forming a directional circulating convective airflow from top to bottom and from inside to outside. This airflow can pass through the first through hole 2011B.

[0069] In one possible design, the power supply system further includes a photovoltaic power generation module 301; the photovoltaic power generation module 301 includes a photovoltaic power generation panel 3012; the photovoltaic power generation panel 3012 is disposed on the side of the first fixing plate 2011 away from the second fixing plate 2012.

[0070] The photovoltaic power generation module 301 can be installed on the airflow guide component 201, and when the wind turbine blade 202 rotates, it can generate airflow from top to bottom and from inside to outside. This airflow can reach the back of the photovoltaic power generation panel 3012 through the first through hole 2011B, which can play a role in heat dissipation of the photovoltaic power generation panel 3012.

[0071] In the power supply system provided in this application embodiment, the energy storage component includes an energy storage battery; the energy storage battery is used to store the electrical energy generated by the photovoltaic power generation module 301, the electrical energy generated by each thermoelectric generator 2013, and the electrical energy generated by the wind turbine blades 202. The power supply system has wind power generation, thermoelectric power generation, and photovoltaic power generation capabilities, and has a strong power supply capacity, which can ensure a stable power supply for the meteorological sensor monitoring module 101.

[0072] Optionally, the number of energy storage batteries can be one or more. Optionally, the energy storage batteries can be, but are not limited to, lithium batteries.

[0073] Optionally, the photovoltaic power generation module 301 further includes a heat dissipation unit 3013; the heat dissipation unit 3013 is disposed on the back of the photovoltaic power generation panel 3012.

[0074] The heat dissipation unit 3013 is used to dissipate heat from the photovoltaic panel 3012. When the wind turbine blade 202 rotates, it can generate airflow from top to bottom and from inside to outside. This airflow can reach the heat dissipation unit 3013 through the first through hole 2011B, which can accelerate the dissipation of photovoltaic preheating and ensure the high-efficiency power generation of the photovoltaic panel 3012.

[0075] In one possible design, please combine Figure 1 and Figure 5A The photovoltaic power generation module 301 further includes a mounting plate 3011; the photovoltaic power generation panel 3012 includes multiple sub-plates 3012A; the multiple sub-plates 3012A are connected sequentially around the axial direction of the mounting plate 3011, and the multiple sub-plates 3012A form a frustum shape.

[0076] Multiple sub-plates 3012A are assembled to form a frustum shape, and each sub-plate 3012A is fixed to the mounting plate 3011. The mounting plate 3011 can be a ring-shaped hollow bearing base. Optionally, the mounting plate 3011 can be made of high-strength aerospace aluminum alloy in one piece. This achieves lightweight, high strength, deformation resistance, and corrosion resistance, making it suitable for long-term exposure to sunlight and wind and sand erosion in the field.

[0077] Multiple sub-panels 3012A are fixed on the mounting plate 3011 and arranged to form a frustum-shaped structure. The overall shape can be umbrella-like, supporting omnidirectional lighting. The sub-panels 3012A can be modularly disassembled and assembled, offering convenient disassembly and maintenance. Furthermore, a damaged individual sub-panel 3012A can be replaced individually without overall disassembly, significantly reducing the maintenance costs of field equipment. In some examples, the sub-panel 3012A can be a fan-shaped monocrystalline photovoltaic panel. Multiple sub-panels 3012A are evenly arranged circumferentially along the mounting plate, and when spliced ​​together, they form an umbrella-shaped slope structure that is narrower at the top and wider at the bottom, i.e., a frustum-shaped structure. This design differs from the limitations of traditional single-plane fixed photovoltaic panels in terms of their limited light-gathering angle. The photovoltaic power generation module 301 provided in this application can support 360° all-round reception of direct sunlight from the outside world, while efficiently capturing sky-scattered light and ground-reflected light in complex environments such as mountains and wilderness. It can still stably collect light and generate electricity under complex conditions such as the shift of the sun angle in the morning and evening, partial shading in the forest, weak light on cloudy days, and backlighting in mountainous areas, which greatly improves the light energy utilization rate and low-light power generation performance in complex outdoor scenarios.

[0078] In some examples, splicing portions are provided on both sides of the sub-board 3012A. The splicing portions of the two sub-boards 3012A cooperate to achieve a fixed connection between the two sub-boards 3012A.

[0079] In one possible design, the photovoltaic power generation module 301 further includes a heat dissipation unit 3013; please refer to... Figure 5B The heat dissipation unit 3013 includes a plurality of heat sinks 3013A; the plurality of heat sinks 3013A correspond one-to-one with the plurality of sub-boards 3012A; any heat sink is attached to the back of the sub-board 3012A corresponding to any heat sink.

[0080] Optionally, the heat dissipation unit 3013 further includes a plurality of support structures 3013B, which correspond one-to-one with the plurality of heat sinks 3013A.

[0081] Any support structure 3013B is disposed on one side of the corresponding heat sink 3013A and back ion plate 3012A. The any support structure 3013B abuts against the first fixing plate 2011, and the any support structure 3013B abuts against the surface of the first fixing plate 2011 away from the second fixing plate 2012.

[0082] In this design, the heat dissipation unit 3013 not only has the function of dissipating heat from the photovoltaic panel, but also plays a role in supporting the photovoltaic panel and improving the photovoltaic module.

[0083] Optionally, any of the heat sinks is attached to the back of the photovoltaic panel 3012 corresponding to the heat sink using thermally conductive silicone.

[0084] Optional, please refer to Figure 5A Multiple photovoltaic heat dissipation fins are connected in sequence to form a frustum shape.

[0085] Optionally, the heat sink can be a photovoltaic heat sink fin. The heat sink adopts a high-density aluminum alloy fin structure, tightly bonded to the back of the photovoltaic panel via high-strength thermally conductive silicone, with no thermal gaps. It has high thermal conductivity and excellent heat dissipation performance, quickly dissipating the high-temperature heat generated by the sub-panel 3012A of the photovoltaic panel 3012 during strong sunlight operation, effectively reducing the operating temperature of the photovoltaic panel, avoiding photoelectric conversion efficiency degradation caused by high temperatures, and ensuring long-term stable photovoltaic power generation efficiency. Simultaneously, the waste heat dissipated by the heat sink can be retained inside the current guiding component 201 through the first through-hole 2011B, providing an auxiliary heat source for the thermoelectric generator 2013, realizing the secondary utilization of photovoltaic waste heat and improving the overall energy utilization rate of the power supply system.

[0086] In some examples, the mounting plate 3011 has a second through hole 3011A at its center, and the meteorological sensor monitoring module 101 passes through the second through hole 3011A and is positioned on top of the first fixing plate 2011.

[0087] The second through hole 3011A in the center of the mounting plate 3011 can serve as a through-hole for cables, allowing signal and power lines of the meteorological sensor monitoring module 101 to pass through, facilitating neat wiring and ensuring waterproof sealing. This enables stable data signal transmission and power supply access. The independent top-mounted arrangement of the sensor monitoring module completely avoids obstruction of the sensor probe and airflow interference from the power generation and protective components below, effectively ensuring the authenticity and accuracy of the meteorological data collected. Optional, please consider... Figure 6 The meteorological sensor monitoring module 101 features an integrated, sealed structure with no exposed precision wiring. A power transmission line is located at the bottom of the module, which can also be used for data transmission. The integrated design of the module provides high dust and water resistance, making it resistant to dust accumulation and damage, requiring minimal maintenance, and perfectly suited for long-term unattended monitoring scenarios in the field.

[0088] The mounting plate 3011 has a tube body and an annular plate. The inner circumference of the annular plate is connected to the outer circumference of the end of the tube body away from the first fixing plate 2011. The tube body extends toward the first fixing plate 2011.

[0089] The mounting plate 3011 structure allows the photovoltaic panel 3012 module and the wind turbine blade 202 below to be suspended and fixed, creating a large, open, non-sealed annular ventilation gap between the upper and lower components. This provides the core structural foundation for active convection cooling and coordinated heat exchange among multiple components, enabling the power supply system to achieve multi-module synergistic efficiency at the structural level. This achieves a synergistic advantage of 1+1>2, where a single structure performs multiple functions and modules mutually enhance each other. The photovoltaic panel 3012, combined with the heat dissipation unit 3013, can construct a dual heat dissipation system of "natural ventilation + passive heat conduction," allowing the photovoltaic module 301 to simultaneously perform power generation, heat dissipation, and protection functions. The structural utilization rate and adaptability to operating conditions are significantly better than traditional equipment.

This completely solves the industry pain points of data transmission interruptions and monitoring gaps in traditional field monitoring equipment, achieving stable data transmission across all regions and around the clock.

[0094] All power management components adopt an integrated layout, with neat wiring, strong anti-interference capabilities, and stable operation. The power management components are the core of the power supply system's energy dispatch, capable of simultaneously receiving power from both wind power and thermoelectric generators. The power management components can perform voltage stabilization, rectification, filtering, equalization charging, and intelligent power distribution. Optionally, if the power supply system also includes a photovoltaic power generation module 301, the power management component can simultaneously receive power from wind power generation, thermoelectric power generation, and photovoltaic power generation. The power management component can perform voltage stabilization, rectification, filtering, equalization charging, and intelligent distribution, achieving complementary and redundant power supply from wind, solar, and thermoelectric energy sources. Excess energy is stored in the energy storage lithium battery pack, continuously discharging under extreme conditions such as cloudy / rainy weather, no wind, and weak temperature differences, ensuring uninterrupted operation of the entire unit.
