[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0020] The environment of high-altitude regions possesses unique climatic characteristics significantly different from those of inland areas. The combined effects of environmental factors can have complex influences on various products and materials, leading to unpredictable quality changes during long-term storage in high-altitude environments. To accurately determine the reliable storage life of products in high-altitude environments, researchers typically employ accelerated aging tests. However, existing high-altitude environment simulation equipment generally suffers from incomplete simulation of environmental factors, making it difficult to accurately reproduce the comprehensive effects of high-altitude environments.

[0021] To address the aforementioned problems, this invention provides a high-altitude and cold-weather environment simulation test device and its usage method. It has the advantages of being able to comprehensively simulate key parameters of the high-altitude environment, such as air pressure, humidity, and ultraviolet radiation intensity, thus solving the problem of incomplete environmental factors in existing equipment and improving the accuracy and reliability of the test.

[0022] Please refer to Figure 1 and Figure 2 This invention proposes a high-altitude and cold-weather environment simulation test device, including a test container 1, an environmental control component 2, and an environmental parameter monitoring component 3. The test container 1 has a sealed cavity 101. The environmental control component 2 is used to adjust multiple environmental parameters of the sealed cavity 101, including air pressure, humidity, and ultraviolet radiation intensity. The environmental parameter monitoring component 3 includes an air pressure monitoring unit 31, an ultraviolet monitoring unit 32, and a humidity monitoring unit 33.

[0023] In the technical solution of this application, by including a test container 1, an environmental control component 2, and an environmental parameter monitoring component 3, it is possible to comprehensively adjust and monitor plateau environmental parameters such as air pressure, humidity, and ultraviolet radiation intensity. This solves the problem of incomplete environmental factors in existing equipment and has the advantages of being able to comprehensively simulate key parameters of the plateau environment, thereby improving the accuracy and reliability of the test.

[0024] Test container 1 is used to contain the test specimen and provide a controlled internal space. This container typically needs to have good sealing performance to ensure the stability and adjustability of internal environmental parameters.

[0025] The test container 1 is a core component of the high-altitude and cold-weather environment simulation test device, and its main function is to provide a sealed and controllable test space. The test container 1 can be implemented in various structural forms. For example, it can be a single-piece cast metal box, forming a naturally sealed cavity 101 inside, with a sealable access port on the box for sample placement. Another implementation is that the test container 1 is assembled from multiple detachable components, such as a base 11, a cylinder 12, and an end cap 13. These components are mechanically connected and supplemented by a sealing structure to jointly enclose the sealed cavity 101. In practical applications, the material of the test container 1 can be selected according to the test requirements; for example, stainless steel, aluminum alloy, or other high-strength materials can be used to withstand internal pressure changes and ensure structural stability.

[0026] The environmental control component 2 is crucial for simulating a high-altitude environment. This component can independently or collaboratively regulate the air pressure, humidity, and ultraviolet radiation intensity within the sealed cavity 101. For air pressure regulation, a pressure regulating component 23, such as a combination of a vacuum pump and a precision valve, can be used to precisely control the air pressure within the cavity through evacuation and replenishment. For example, a vacuum pump can be connected to the sealed cavity 101, and the internal air pressure can be reduced by controlling the pump's operating time or power; simultaneously, an inlet valve can be installed to introduce external gas when needed to increase the cavity pressure. For humidity regulation, a humidifier or dehumidifier can be used in conjunction with a humidity sensor. For example, an ultrasonic humidifier can be introduced, and the cavity humidity can be increased by controlling its operating time or atomization rate; alternatively, humidity can be reduced by introducing a desiccant or a condensation dehumidification device. For ultraviolet radiation intensity regulation, an ultraviolet light source can be used in conjunction with a power controller 5. For example, an ultraviolet lamp 21 can be installed outside or inside the test container 1, and the intensity of ultraviolet radiation emitted by the ultraviolet lamp 21 can be changed by adjusting the power supply voltage or current of the ultraviolet lamp 21.

[0027] The environmental parameter monitoring component 3 is a crucial element in ensuring precise control of environmental parameters and the reliability of test data. This component integrates multiple sensors to acquire environmental data within the sealed cavity 101 in real time. The air pressure monitoring unit 31 can employ a high-precision pressure sensor, such as a piezoresistive or capacitive sensor, mounted on the wall of the sealed cavity 101 and connected to the data acquisition system via wires, outputting the absolute air pressure value inside the cavity in real time. The ultraviolet monitoring unit 32 can employ an ultraviolet photodiode or an ultraviolet radiometer, placed inside the sealed cavity 101 or through a light-transmitting window to receive ultraviolet radiation inside the cavity, converting the signal into an electrical signal, and transmitting it to the data processing unit to display the current ultraviolet radiation intensity. The humidity monitoring unit 33 can employ a capacitive or resistive humidity sensor, mounted inside the sealed cavity 101, measuring the relative or absolute humidity inside the cavity in real time and transmitting the data to a display or control system. These monitoring units work together to provide feedback to the environmental control component 2, thereby achieving closed-loop control of environmental parameters.

[0028] In some embodiments described above in this application, a high-altitude and cold-weather environment simulation test device is proposed, which includes a test container 1 with a sealed cavity 101 for simulating a high-altitude environment. However, in practical applications, how to conveniently and reliably construct and maintain the sealed cavity 101, and how to conveniently place or remove samples, are technical problems that need to be solved.

[0029] Please refer to the following for details. Figures 1 to 3This application further proposes that the test container 1 includes a base 11, a cylindrical body 12, and an end cap 13. The base 11 serves as the basic support structure of the test container 1 in the high-altitude and cold-climate environment simulation test device, bearing the weight of the entire test container 1 and providing a stable mounting interface for other components. The base 11 can be made of various materials; for example, high-strength, corrosion-resistant metal materials such as stainless steel or aluminum alloy can be selected to ensure structural stability and long service life; or polymer composite materials can be used to reduce overall weight and provide good insulation performance. The bottom of the base 11 can be designed with mounting holes for fixing the device, so that the entire device can be stably installed on a workbench or in a high-low temperature alternating test chamber. The cylindrical body 12 is the main sidewall part constituting the sealed cavity 101, and its internal space is used to place the test specimen. The cylindrical body 12 can be designed in various geometric shapes, such as cylindrical, square, or polygonal, to accommodate specimens of different shapes and sizes. The choice of material for the cylinder 12 is crucial. A metal material with good mechanical strength and pressure resistance, such as stainless steel, can be used to withstand internal pressure changes. Alternatively, for easier observation of the internal sample state, the cylinder 12 can be made of a transparent material, such as high-strength glass or polycarbonate, while ensuring sufficient pressure resistance and sealing performance. The end cap 13 is used to close the top of the cylinder 12, together with the base 11 and the cylinder 12, to complete the enclosure of the sealed cavity 101. The design of the end cap 13 needs to match the connection method of the cylinder 12 and the base 11 to ensure the reliability and sealing of the connection. The material of the end cap 13 can be the same as that of the base 11 or the cylinder 12, such as metal or high-strength plastic. An interface can also be reserved on the end cap 13 for connecting the sensors of the environmental control component 2 or the environmental parameter monitoring component 3. The cylinder 12 is detachably connected to the base 11, and the end cap 13 covers the detachably connected end of the cylinder 12 away from the base 11. The detachable connection refers to the non-permanent connection between the base 11 and the cylinder 12, and between the cylinder 12 and the end cap 13. This connection method allows the components to be separated and reassembled without damaging them. There are various ways to implement the detachable connection. For example, a threaded connection can be used, where fastening and disassembly are achieved by screwing in the threads; a flange connection can be used, where the flanges are fastened together with bolts and nuts; or a snap-fit ​​connection or quick coupling can be used for faster assembly and disassembly. The base 11, cylinder 12, and end cap 13 together form the sealed cavity 101. The base 11, cylinder 12, and end cap 13, through tight fitting and connection, together form a sealed cavity 101 that isolates the interior from the external environment. To ensure the airtightness of the sealed cavity 101, seals, such as O-rings, flat gaskets, or liquid sealant, are typically used at each connection interface.These seals can effectively fill the tiny gaps at the joints, preventing gas or moisture leakage, thereby ensuring precise control and simulation of the internal environmental parameters of the sealed cavity 101.

[0030] The test container 1 of this application is formed by detachably connecting the base 11, the cylinder 12, and the end cap 13 to create a sealed cavity 101. This structural design makes the overall construction of the test container 1 modular, greatly improving the ease of assembly, disassembly, and maintenance of the device. Specifically, when it is necessary to place the test sample into the sealed cavity 101, the operator can easily open the sealed cavity 101 by disassembling the connection between the end cap 13 or the cylinder 12 and the base 11, and place the sample into the preset position on the base 11 or inside the cylinder 12. After placing the sample, the end cap 13 or the cylinder 12 is reconnected and tightened, and the sealing element ensures the airtightness of the sealed cavity 101. Similarly, after the test is completed, when it is necessary to remove the sample, perform internal cleaning, or maintain the internal components of the device, the same detachable connection method can be used to complete the operation quickly and conveniently. This design not only ensures the integrity and precise sealing performance of the sealed cavity 101 in simulated high-altitude environments, but also significantly improves the flexibility and efficiency of test operations, effectively solving many inconveniences faced by traditional integrated or difficult-to-disassemble test containers 1 in terms of sample loading and unloading and device maintenance.

[0031] In the aforementioned high-altitude and frigid environment simulation test device, the test container 1 is detachably connected and enclosed by a base 11, a cylindrical body 12, and an end cap 13 to form a sealed cavity 101. However, in practical applications, this detachable connection method may face problems such as inadequate sealing and unstable connections. Especially when simulating high-altitude environments, environmental parameters such as air pressure and humidity inside the sealed cavity 101 need to be precisely controlled. Once leakage occurs, it will seriously affect the accuracy and reliability of the test. In addition, frequent disassembly and installation may also lead to wear at the connection points, further increasing the risk of seal failure.

[0032] In response, this application further proposes a threaded connection between the cylinder 12 and the base 11, with a sealing gasket provided; and a threaded connection between the end cap 13 and the cylinder 12, with a sealing gasket provided. The sealing gasket can be an O-ring, placed in the annular groove at the connection, and compressed when the threaded connection is tightened; or, the sealing gasket can be a flat gasket, placed on the contact surface of the connection, and deformed by the clamping force of the threaded connection.

[0033] In some embodiments described above in this application, a high-altitude and cold-weather environment simulation test device is proposed. Its test container 1 is formed by a base 11, a cylinder 12, and an end cap 13, creating a sealed cavity 101. It also includes an environmental control component 2 and an environmental parameter monitoring component 3, capable of adjusting and monitoring environmental parameters such as air pressure and humidity within the sealed cavity 101. However, in simulating high-altitude environments, ultraviolet radiation is an indispensable environmental factor. The basic structure of the test container 1 does not explicitly provide a method for introducing ultraviolet radiation, which limits the comprehensiveness and realism of the simulation test.

[0034] In this regard, this application further proposes that the cylinder 12 is at least partially light-transmitting, and the environmental control component 2 includes an ultraviolet lamp 21 disposed on the base 11 and located outside the cylinder 12.

[0035] The cylinder 12 is at least partially light-transmitting, meaning that a portion or the entire cylinder 12 of the test container 1 allows light of a specific wavelength (specifically ultraviolet light) to pass through. The cylinder 12 can be made of transparent or translucent materials, such as quartz glass or special optical plastics (e.g., polycarbonate, acrylic resin, etc., whose ultraviolet transmittance and weather resistance must be considered). Alternatively, one or more light-transmitting windows can be provided on the cylinder 12, made of ultraviolet-transmitting materials and sealed to the main structure of the cylinder 12. Their function is to ensure that ultraviolet radiation emitted by an external light source can effectively enter the sealed cavity 101 to irradiate the sample inside the cavity. The environmental control component 2 includes an ultraviolet lamp 21, meaning that the environmental control component 2 integrates a light source capable of emitting ultraviolet radiation to simulate the ultraviolet irradiation conditions present in a high-altitude environment. The ultraviolet lamp 21 is mounted on the base 11, meaning that the ultraviolet lamp 21 is installed on the base 11 component of the test container 1. The ultraviolet lamp 21 can be directly fixed to the surface or pre-reserved mounting groove inside the base 11, or it can be mounted on the base 11 via a bracket or connector to ensure its stability. The ultraviolet lamp 21 is located outside the cylinder 12, meaning it is spatially positioned outside the cylinder 12 and does not directly contact the internal environment of the sealed cavity 101. The ultraviolet lamp 21 can be mounted on the base 11 and arranged around the outer wall of the cylinder 12, or mounted on a bracket above the base 11, allowing its light to reach the light-transmitting portion of the cylinder 12 from the outside. Its purpose is to prevent the ultraviolet lamp 21 from being directly exposed to extreme environments such as high pressure, low pressure, high humidity, or low humidity inside the sealed cavity 101, thereby protecting the lamp, extending its service life, and simplifying the structural design of the sealed cavity 101.

[0036] In the high-altitude and frigid environment simulation test device, to simulate ultraviolet radiation, the cylindrical body 12 of the test container 1 is designed to be at least partially transparent. This means that a portion of the material of the cylindrical body 12 allows ultraviolet light to penetrate. Ultraviolet lamps 21 are integrated into the environmental control component 2. These lamps 21 are cleverly positioned on the base 11 and located on the outside of the cylindrical body 12. When the ultraviolet lamps 21 are working, the ultraviolet radiation they emit can penetrate the transparent portion of the cylindrical body 12 and enter the sealed cavity 101, thereby irradiating the sample inside the cavity with ultraviolet light. This arrangement eliminates the need for the ultraviolet lamps 21 to be directly exposed to the special environment inside the sealed cavity 101 (such as low air pressure and high humidity), avoiding performance degradation or damage to the lamps under extreme conditions, and also simplifying the sealing structure design of the sealed cavity 101. In this way, the high-altitude and frigid environment simulation test device can effectively introduce ultraviolet radiation while maintaining independent control of the environmental parameters (such as air pressure and humidity) inside the sealed cavity 101, thus more comprehensively simulating the combined effects of the high-altitude environment.

[0037] Through the above technical solution, the high-altitude and frigid environment simulation test device can effectively introduce ultraviolet radiation to irradiate the samples inside the sealed cavity 101. This design avoids the ultraviolet lamp 21 being directly exposed to the extreme environment inside the sealed cavity 101, protecting the lamp, extending its service life, and simplifying the structural design of the sealed cavity 101. At the same time, through the light-transmitting setting of the cylinder 12, ultraviolet radiation can still effectively enter the cavity, thereby realizing the simulation of ultraviolet radiation in the high-altitude environment. This allows the test device to more comprehensively and realistically simulate the comprehensive high-altitude environment, improving the accuracy and reliability of the simulation test.

[0038] This application further proposes that the cylindrical body 12 is made of a transparent material, and that multiple ultraviolet lamps 21 are provided, with the multiple ultraviolet lamps 21 distributed along the circumference of the cylindrical body 12.

[0039] The distribution of multiple ultraviolet lamps 21 along the circumference of the cylindrical body 12 means that these multiple ultraviolet lamps 21 are arranged uniformly or non-uniformly around the outer periphery of the cylindrical body 12. For example, the multiple ultraviolet lamps 21 can be arranged at equal intervals around the outer wall of the cylindrical body 12, such as in a circular or polygonal array. Alternatively, they can be densely arranged in a specific area around the cylindrical body 12 to simulate ultraviolet radiation in a specific direction, depending on the experimental requirements.

[0040] The proposed solution uses a transparent material for the cylinder 12, ensuring that the ultraviolet radiation emitted by the ultraviolet lamp 21 can penetrate the wall of the cylinder 12 without obstruction and enter the sealed cavity 101. Furthermore, the ultraviolet lamp 21 in the environmental control component 2 is no longer a single light source, but rather multiple lamps are arranged, and these multiple ultraviolet lamps 21 are evenly distributed circumferentially along the cylinder 12. This multi-source, circumferentially surrounding layout allows ultraviolet radiation to enter the sealed cavity 101 from all directions of the cylinder 12. When the ultraviolet lamp 21 is working, the ultraviolet radiation it emits enters the sealed cavity 101 through the transparent cylinder 12. Due to the circumferential distribution of the light sources, the ultraviolet lamps 21 at different positions work together, allowing the sample inside the sealed cavity 101 to receive ultraviolet radiation from different angles, thereby forming a more uniform ultraviolet radiation field on the sample surface. This design effectively avoids radiation dead zones and intensity differences that may be caused by a single light source or localized light transmission, significantly improving the uniformity and realism of the ultraviolet radiation environment in the simulation experiment.

[0041] In some embodiments described above in this application, a high-altitude and cold-weather environment simulation test device is proposed. Its test container 1 has a sealed cavity 101, and the humidity of the sealed cavity 101 can be adjusted by an environmental control component 2. However, in actual operation, how to accurately and conveniently introduce or adjust humidity into the sealed cavity 101 without compromising the stability of the internal environment is a technical problem that needs to be solved. Traditional humidity introduction methods may require frequent opening and closing of the sealed cavity 101, which not only affects the stability of the air pressure and temperature inside the cavity but may also introduce external contaminants, thereby affecting the accuracy and reliability of the test results.

[0042] Please refer to the following for details. Figure 4This application further proposes an environmental control component 2 including a humidity regulator 22 disposed on an end cap 13. The humidity regulator 22 is a component for introducing or regulating humidity into or inside the sealed cavity 101. It can be integrated into the end cap 13 as part of the environmental control component 2 to achieve precise control of the humidity inside the sealed cavity 101. The humidity regulator 22 can be a separate module or an integrally formed structure with the end cap 13. The humidity regulator 22 includes an adjusting nozzle 221, which is disposed on the end cap 13 and has one end communicating with the sealed cavity 101. The adjusting nozzle 221 is a key component of the humidity regulator 22; one end is communicating with the sealed cavity 101, and the other end is exposed for connecting to an external humidity source or injecting humidifying gas. The adjusting nozzle 221 can have a tubular structure, and its inner diameter and length can be designed according to actual needs to ensure smooth fluid transmission. The humidity regulator 22 also includes two annular limiting portions 222, which are spaced apart between the adjusting nozzles 221. The two annular limiting portions 222 primarily function to fix and limit the puncture-resistant sealing plug 223. They can be protrusions integrally formed on the regulating nozzle 221, or they can be independently machined and fixed to the regulating nozzle 221. For example, they can be two annular grooves on the inner wall of the regulating nozzle 221, or two annular flanges on the outer wall of the regulating nozzle 221. The humidity regulating component 22 further includes a puncture-resistant sealing plug 223, made of an elastic material, and sealed between the two annular limiting portions 222. The puncture-resistant sealing plug 223 is the core sealing component of the humidity regulating component 22, effectively preventing communication between the sealed cavity 101 and the external environment under normal conditions, ensuring the airtightness of the sealed cavity 101. When humidity needs to be introduced, the humidifying medium can be injected through puncture. The selection of the elastic material is crucial; for example, materials with good elasticity and chemical corrosion resistance, such as silicone rubber, butyl rubber, or fluororubber, can be selected. In addition, the humidity regulator 22 includes a puncture-resistant sealing cap 224, which is fitted onto the end of the regulating nozzle 221 furthest from the end cap 13. The main function of the puncture-resistant sealing cap 224 is to protect the puncture-resistant sealing plug 223 from external contamination and physical damage, and to provide additional sealing protection. The sealing cap can be made of the same material as the puncture-resistant sealing plug 223 to facilitate puncture.

[0043] The solution of this application achieves humidity regulation of the internal cavity 101 without compromising its overall sealing performance by setting a humidity regulating component 22 on the end cap 13. Specifically, one end of the regulating nozzle 221 in the humidity regulating component 22 is connected to the sealing cavity 101, providing a channel for the introduction of the humidifying medium. Two annular limiting parts 222 precisely fix the puncturable sealing plug 223 at a specific position on the regulating nozzle 221, ensuring the stability and sealing effect of the sealing plug. The puncturable sealing plug 223 is made of elastic material and can reliably block the connection between the regulating nozzle 221 and the external environment under normal conditions, thereby maintaining the stability of the air pressure and humidity inside the sealing cavity 101. When it is necessary to regulate the humidity inside the sealing cavity 101, the operator can puncture the puncturable sealing plug 223 with an external device (such as a syringe or a moisture generator) to inject a preset amount of humidifying medium (such as water vapor or humid air) into the sealing cavity 101. Due to the elastic properties of the sealing plug, the puncture hole can automatically or quickly close under external pressure after the puncture tool is removed, restoring its sealed state and thus avoiding drastic fluctuations in the internal environment of the sealed cavity 101. Furthermore, the puncturable sealing cap 224 is fitted onto the end of the adjusting nozzle 221 furthest from the end cap 13, providing additional physical protection and sealing for the puncturable sealing plug 223, further reducing the potential impact of the external environment on the sealing plug and ensuring the reliability of the humidity regulation process and the long-term stability of the sealed cavity 101. This design cleverly solves the problem of humidity regulation in a sealed environment, enabling the high-altitude and cold-weather environment simulation test device to more accurately and stably simulate the required high-altitude humidity environment.

[0044] In other embodiments, this application proposes a high-altitude and cold-weather environment simulation test device, which includes a test container 1, an environmental control component 2, and an environmental parameter monitoring component 3, capable of adjusting and monitoring environmental parameters within a sealed cavity 101. However, in actual operation, without an intuitive and integrated display and control interface, users may need to rely on external devices or go through cumbersome steps to obtain real-time environmental parameter information and accurately operate the environmental control component 2. This not only reduces the convenience of operation but may also affect the efficiency and accuracy of the experiment.

[0045] In this regard, this application further proposes that the above-mentioned high-altitude and cold environment simulation test device also includes a display 4 and a controller 5 installed on the base 11; the display 4 is used to display multiple environmental parameters; and the controller 5 is used to control multiple environmental parameters.

[0046] The solution in this application integrates a display 4 and a controller 5 on the base 11 of the high-altitude and cold-weather environment simulation test device, realizing intuitive display and precise control of the internal environmental parameters of the sealed cavity 101. Specifically, the environmental parameter monitoring component 3 continuously collects data such as air pressure, humidity, and ultraviolet radiation intensity inside the sealed cavity 101 and transmits this data to the controller 5. After receiving the monitoring data, the controller 5 processes it and sends it to the display 4, allowing the user to view the current values ​​and trends of various environmental parameters in real time and clearly. On the other hand, the controller 5 analyzes and judges the monitoring data according to the instructions input by the user through the display 4 or controller 5 interface, or according to the preset test program. When the monitored environmental parameters deviate from the preset target value, the controller 5 generates a corresponding control signal and sends it to the environmental control component 2. After receiving the control signal, the environmental control component 2 executes corresponding adjustment actions, such as starting or stopping the air pump, adjusting the operating status of the humidification or dehumidification equipment, or changing the output power of the ultraviolet lamp 21, thereby adjusting the environmental parameters inside the sealed cavity 101 to the target range. This integrated design allows users to monitor, set, and adjust environmental parameters directly next to the device without needing to connect external equipment, greatly simplifying the operation process and improving the convenience and efficiency of the experiment.

[0047] The present invention also proposes a high-altitude and cold environment simulation test device, which further includes a high-low temperature alternating test chamber, and the test container 1 is placed inside the high-low temperature alternating test chamber.

[0048] The core innovation of this embodiment lies in combining the high-altitude and frigid environment simulation test device with the high-low temperature alternating test chamber in a nested structure. This achieves the synergistic simulation of key environmental factors in high-altitude areas, such as temperature, air pressure, humidity, and ultraviolet radiation intensity. This solves the problem in existing technologies that cannot comprehensively simulate the synergistic effects of multiple factors in high-altitude and frigid environments, resulting in simplified structure, enhanced versatility, and reduced cost. Specifically, high-altitude environments are characterized by low air pressure, strong ultraviolet radiation, low temperature, and large temperature differences. Existing equipment either fails to accurately reproduce the multi-factor coupling effects of high-altitude areas due to insufficient simulation factors (such as missing ultraviolet and air pressure parameters), or is costly due to complex structure, poor versatility, and high cost. This application integrates the aforementioned test container 1 entirely into the high-low temperature alternating test chamber, allowing the chamber to be specifically responsible for precise temperature control, while the high-altitude and frigid environment simulation test device independently adjusts and monitors air pressure, humidity, and ultraviolet radiation intensity. The two complement each other functionally.

[0049] Furthermore, the aforementioned high-altitude and cold-weather environment simulation test device includes a test container 1, an environmental control component 2, and an environmental parameter monitoring component 3. The test container 1 provides a sealed cavity 101 to accommodate the sample. The environmental control component 2 can adjust air pressure, humidity, and ultraviolet radiation intensity. The environmental parameter monitoring component 3 provides real-time feedback of data from the air pressure monitoring unit 31, the ultraviolet monitoring unit 32, and the humidity monitoring unit 33. Since the high-low temperature alternating test chamber already possesses mature temperature control capabilities, using it as an external environmental carrier avoids the complex design of integrating all environmental parameter control modules into a single device, thus significantly simplifying the system structure.

[0050] The solution presented in this application effectively overcomes the structural redundancy of existing multi-factor simulation equipment by rationally decoupling and coordinating functional modules. Compared to traditional integrated designs, this system does not require simultaneous handling of the complex interactions of temperature, air pressure, humidity, and ultraviolet radiation within a single chamber, thus lowering the technical barriers to sealing and control precision. Furthermore, the high and low temperature alternating test chamber, as a general-purpose device, can be adapted to test containers of different specifications, enhancing the system's scalability. Through the above technical solutions, the plateau environment simulation test system not only realistically reproduces the multi-factor synergistic effects of the high-altitude and frigid environment but also significantly reduces manufacturing and maintenance costs due to its modular design, providing an economical and efficient solution for product reliability testing.

[0051] Please refer to Figure 5 This application also proposes a method for using a high-altitude and frigid environment simulation test device, applicable to such a device. The method for using the high-altitude and frigid environment simulation test device includes: S10: Place the sample in the sealed cavity 101; S20: Adjust the air pressure and humidity of the sealed cavity 101 to preset values ​​using the environmental control component 2; S30: Place test container 1 inside the high and low temperature alternating test chamber; S40: Start the temperature change program of the high and low temperature alternating test chamber and adjust the ultraviolet radiation intensity.

[0052] The core innovation of this application lies in combining the test container 1 with the high and low temperature alternating test chamber by adjusting environmental parameters in stages, thereby achieving a synergistic simulation of multiple factors in the plateau environment. Specifically, firstly, the air pressure and humidity of the sealed cavity 101 are independently adjusted to preset values ​​using the environmental control component 2 to ensure accurate simulation of low air pressure and specific humidity environments; then, the entire plateau and frigid environment simulation test device is placed inside the high and low temperature alternating test chamber, and the temperature change program of the high and low temperature alternating test chamber is activated to simulate the plateau temperature characteristics, while the ultraviolet irradiation intensity is simulated through the environmental control component 2.

[0053] Due to the synergistic effects of multiple factors in the plateau environment, precise control of various environmental parameters is required. This application employs a step-by-step adjustment strategy to effectively avoid mutual interference between parameters. Addressing the structural complexity issues arising from existing technologies where a single device attempts to simultaneously simulate all environmental factors, this application rationally divides the tasks. Temperature regulation is handled by a dedicated high-low temperature alternating test chamber, while the environmental control component 2 focuses on regulating air pressure, humidity, and ultraviolet radiation. This significantly simplifies the equipment structure, improves versatility, and reduces costs.

[0054] In practical implementation, the environmental control component 2 can precisely control the air pressure, humidity, and ultraviolet radiation within the sealed cavity 101, meeting the simulation requirements of low air pressure, specific humidity environments, and ultraviolet radiation at high altitudes. Simultaneously, the high and low temperature alternating test chamber provides precise temperature change programs to simulate the temperature characteristics of high-altitude environments. This technical solution, through division of labor and collaboration, ensures precise control of various environmental parameters while avoiding problems caused by excessive equipment integration.

[0055] The above technical solutions can realistically simulate the synergistic effects of multiple factors in high-altitude and cold environments, providing an effective means for reliability testing of products in high-altitude environments and solving the technical problems of existing equipment being insufficient in simulating environmental factors, having complex structures, lacking versatility, and being costly.

[0056] In some of the above embodiments, the method of using the high-altitude and cold-weather environment simulation test device includes adjusting the air pressure and humidity of the sealed cavity 101 to preset values ​​through the environmental control component 2. However, in actual operation, if humidity adjustment is performed immediately before the air pressure has fully stabilized, it may cause the air pressure to fluctuate again, thereby affecting the accuracy and stability of the simulated environment and reducing the reliability of the test results.

[0057] Please refer to the following for details. Figure 6 This application further proposes a step of adjusting the air pressure and humidity of the sealed cavity 101 to preset values ​​using the environmental control component 2, including: S21: Adjust the air pressure of the sealed cavity 101 to the preset air pressure value through the environmental control component 2; S22: Preset settling time; S23: Determine whether the air pressure in the sealed cavity 101 is less than the preset fluctuation threshold; S24: If it is less than the preset humidity value, the humidity of the sealed cavity 101 is adjusted to the preset humidity value by the environmental control component 2.

[0058] Specifically, the environmental control component 2 adjusts the air pressure in the sealed cavity 101 to a preset air pressure value. The environmental control component 2 may include a vacuum pump, an air source, a pressure sensor, and corresponding control valves. The vacuum pump evacuates the sealed cavity 101, or the air source fills the sealed cavity 101 with air. Combined with real-time monitoring of the air pressure inside the sealed cavity 101 by the pressure sensor, the controller 5 precisely controls the vacuum pump, air source, and control valves according to the preset air pressure value to achieve rapid and accurate air pressure regulation.

[0059] The preset settling time is designed to provide a period of time for the air pressure within the sealed cavity 101 to stabilize, eliminating any instantaneous fluctuations that may occur during adjustment. Simultaneously, the settling process also helps to test the sealing performance of the sealed cavity 101. If a minor leak exists, the air pressure will continuously change during the settling period, thus providing a stable basis for subsequent humidity adjustment. The preset time can be set according to the size of the sealed cavity 101, the range of air pressure adjustment, and the required level of stability.

[0060] The process of determining whether the air pressure in the sealed cavity 101 is less than a preset fluctuation threshold is used to confirm whether the air pressure inside the sealed cavity 101 has reached a sufficiently stable state. Air pressure data is continuously collected by the air pressure monitoring unit 31, and the controller 5 analyzes this data, for example, calculating the maximum fluctuation range or rate of change of air pressure during a settling period. If the air pressure fluctuation range or rate of change is less than the preset fluctuation threshold, the air pressure is considered stable. The preset fluctuation threshold can be set according to the requirements of the test for air pressure stability; for example, it can be set as a certain percentage of the preset air pressure value. If it is less than this threshold, the humidity of the sealed cavity 101 is adjusted to a preset humidity value by the environmental control component 2. Once the air pressure is confirmed to be stable, the environmental control component 2 will activate the humidity adjustment function.

[0061] The proposed solution decouples air pressure regulation from humidity regulation and introduces an air pressure stability judgment mechanism to ensure precise control of simulated environmental parameters. First, the environmental control component 2 rapidly adjusts the air pressure within the sealed cavity 101 according to a preset air pressure value. After initial adjustment, the system enters a static state, allowing the air pressure within the sealed cavity 101 to fully stabilize, during which time the air pressure monitoring unit 31 continuously monitors pressure changes. The controller 5 determines whether the air pressure fluctuation during the static period is less than a preset fluctuation threshold to confirm whether the air pressure has reached the stable level required for the experiment. Only after the air pressure is confirmed to be stable will the environmental control component 2 activate the humidity regulation function, adjusting the humidity within the sealed cavity 101 to a preset humidity value. This step-by-step regulation strategy with stability judgment avoids mutual interference during air pressure and humidity regulation, ensuring that the air pressure environment is stable before humidity regulation, thus providing a more accurate and stable high-altitude simulation environment for the sample.
