[0050] The following will provide a clear and complete description of the concept, specific structure and technical effects of this application in combination with the embodiments and drawings to fully understand the purpose, scheme and effect of this application.

[0051] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. The step numbers in the following embodiments are provided solely for ease of illustration and do not limit the order of the steps. The order of execution of the steps in the embodiments can be adjusted adaptively based on the understanding of those skilled in the art. Furthermore, for the following embodiments, "several" is represented as "at least one."

[0052] Currently, the development and production of artificial weathering test equipment primarily utilizes microcontrollers and programmable logic controllers (PLCs) as the core components of centralized control systems. However, with the widespread application of polymer materials, artificial weathering accelerated weathering test equipment is now widely used as a key component for verifying material anti-aging properties and assessing material lifespan. However, equipment networking and remote control are still limited to remote computer connections, significantly limiting data acquisition density and transmission speed. This makes it difficult to interconnect multiple devices and ensure the transmission of large amounts of test data. Furthermore, UV weathering test chambers currently primarily utilize UVA and UVB light sources. The UVA band has a wavelength of 320-400nm, while the UVB band has a wavelength of 275-320nm. Currently, there is no UV irradiation equipment capable of irradiating wavelengths below 275nm. This wavelength is primarily concentrated in the outer space ultraviolet band, which contains short-wavelength ultraviolet rays below 275nm. Due to various factors, UVC is becoming increasingly popular as a surface disinfection method. It is primarily used in automotive interiors, trains, aircraft, textiles, plastics, and coated surfaces, as well as furniture in public, educational, and health facilities. Ultraviolet (UVC) radiation is significantly more corrosive to most materials than sunlight, potentially adding a new risk factor for product failure. Household sterilizers contain UV radiation below 275nm. This exposure to UVC radiation in space environments has created new market demand for aging and lifespan assessment of space materials. This also creates new requirements for intensive data transmission and remote monitoring of aging equipment within remote industrial interconnections.

[0053] At present, the shortcomings of UV aging test equipment in terms of data interconnection, remote monitoring and optical band coverage are as follows:

[0054] (1) UV aging test equipment generally uses traditional USB transmission methods and network port transmission methods in PLC and single-chip microcomputer modules for industrial networking and remote monitoring functions. This causes delays in large amounts of real-time test data and is unable to achieve the functional requirements of remotely viewing the usage status of each component of the equipment and remotely operating the equipment;

[0055] (2) The current UV aging chamber does not have the UVC light band ultraviolet radiation function, and cannot provide life assessment work for the current polymer materials for the use and aging of such short-wave ultraviolet environments;

[0056] (3) There is a structural uniqueness in the current UV aging test equipment, which cannot be compatible with the flat-panel UV aging box suitable for GB / T16776 silicone sealant, which is currently suitable for most of the trapezoidal structures suitable for coatings, paints, plastics, and rubbers.

[0057] like Figure 1As shown, an embodiment of the present application provides an ultraviolet aging test device based on UVC radiation waves, including a processor, a UVC irradiation module, a wireless communication module, a structure conversion module and a temperature and humidity control module. The processor can adopt an STM32 microcontroller.

[0058] The UVC irradiation module includes a UVC photosensor, an integrated amplifier and filter circuit, a UVC ballast, a UVC ultraviolet light source, a ballast current feedback submodule, and a ballast temperature feedback submodule. Users can set the irradiance setpoint via remote input from a wireless communication module, touch input via a touch screen, or other input methods. Upon receiving the irradiance setpoint, the processor controls the UVC ultraviolet light source to emit UVC light. The UVC photosensor collects UVC light from the environment and performs photoelectric conversion to generate a measurement photoelectric signal. This measurement photoelectric signal is then transmitted to the integrated amplifier and filter circuit for pre-amplification, buffering, and hardware filtering. Analog-to-digital conversion and digital filtering are then performed to generate a photoelectric measurement value, which is then input into the processor. The processor generates a photoelectric control signal based on the difference between the photoelectric measurement value and the irradiance setpoint. This photoelectric control signal is then transmitted to the UVC ballast for ballasting, which then acts on the UVC ultraviolet light source, achieving feedback regulation of the UVC ultraviolet light source. The ballast current feedback submodule collects the ballast's output current, determines its stability, and thus its health. If the ballast output current exceeds ±5% of the ballast's maximum output current, the system displays an alarm, prompting the need for ballast replacement. The ballast temperature feedback submodule collects the ballast's operating temperature. If the upper limit of 80°C is reached, an alarm is issued and the system shuts down.

[0059] In some embodiments, the processor can also calculate the output power of the ballast based on the output current of the ballast, and calculate the energy conversion ratio of the UVC ultraviolet light source based on the output power of the ballast and the photoelectric measurement value. When the energy conversion ratio falls below a preset threshold, the processor will issue an alarm. At the same time, the processor can collect the operating time of the UVC ultraviolet light source and derive the health status and remaining service life of the light source based on the energy conversion ratio and the operating time of the UVC ultraviolet light source, and display the status information and light source replacement reminder information on the touch screen.

[0060] The structure conversion module includes a sample rack, a sample rack rotation motor, a light source rack, and a light source rack rotation motor. The user can set the structure of the UV aging test equipment through the wireless communication module remote input method, the touch screen touch input method, or other input methods. The processor generates a structure conversion signal based on the input. When the user selects the horizontal structure, if the UV aging test equipment is in a trapezoidal structure, the processor will generate a horizontal conversion signal. Figure 2 and Figure 3The interior of the UV aging test equipment is a trapezoidal rectangular structure, consisting of sample racks on both sides and light sources parallel to the sample racks. Four light sources and four integral mechanical transmission motors are set on one side of the UV aging test equipment, and the mechanical transmission motors all use zipper-type motion. The sample rack includes a first sample rack 101 and a second sample rack 102, the light source rack includes a first light source rack 103 and a second light source rack 104, the corresponding sample rack rotation motor includes a first sample rack rotation motor 105 and a second sample rack rotation motor 106, and the light source rack rotation motor includes a first light source rack rotation motor 107 and a second light source rack rotation motor 108. After receiving the horizontal conversion signal, the second light source rack rotation motor 108 will drag the second light source rack 104 to rotate counterclockwise along the upper side to a horizontal position, and then the first light source rack rotation motor 107 will drag the first light source rack 103 to rotate counterclockwise to a horizontal position, and the light source rack rotation is now complete. After the light source racks have all rotated to a horizontal position, the first rack rotation motor 105 will rotate the first rack 101 clockwise to a horizontal position, and the second rack rotation motor 106 will rotate the second rack 102 counterclockwise to a horizontal position, thereby completing the horizontal configuration of the UV aging tester. When the user selects the trapezoidal configuration, if the UV aging tester is in a horizontal configuration, the processor will generate a trapezoidal conversion signal. Upon receiving the trapezoidal conversion signal, the first rack rotation motor 105 will rotate the first rack 101 counterclockwise to the trapezoidal hypotenuse position of the UV aging tester, and the second rack rotation motor 106 will rotate the second rack 102 clockwise to the trapezoidal hypotenuse position of the UV aging tester. After the sample racks are rotated to the trapezoidal hypotenuse position, the first light source rack rotating motor 107 will drag the first light source rack 103 to rotate clockwise to a position parallel to the first sample rack 101, and then the second light source rack rotating motor 108 will drag the second light source rack 104 to rotate clockwise to a position parallel to the second sample rack 102, thereby completing the trapezoidal structure conversion of the ultraviolet aging test equipment. During the rotation of the rotating motor, a locator can be used to position the sample rack. The locator is a fixed component fixed to the end position of the sample rack movement. The locator has a built-in electromagnetic switch. When the sample rack contacts the locator during the rotation process, the built-in magnetic switch of the locator is closed. At this time, the magnetic switch outputs a switch electrical signal to the processor, and the system determines that the movement is completed and ends the movement. The main function of the locator is to prevent the final moving position from having a slight deviation when the trapezoidal structure and the horizontal structure inside the equipment are mechanically rotated, which may affect the irradiance, temperature and humidity of the ultraviolet aging test equipment.

[0061] The temperature and humidity control module includes a temperature sensor, a humidity sensor, a heater, a humidity controller, a temperature calibration probe, and a humidity calibration probe. The temperature sensor can be a blackboard thermometer, and temperature and humidity control can be performed using a PID algorithm. Users can set the set temperature and humidity of the UV aging test equipment through remote input via a wireless communication module, touch input via a touch screen, or other input methods. After receiving the set temperature, the processor uses the temperature sensor to collect the UV aging test equipment's measured temperature and transmits it to the processor. The processor compares the measured temperature with the set temperature. If the measured temperature is lower than the set temperature, a temperature control signal is generated based on the difference between the set and measured temperatures. The temperature control signal is transmitted to the heater, which adjusts its output power based on the temperature control signal. After receiving the set humidity, the processor uses the humidity sensor to collect the measured humidity of the UV aging test equipment and transmits it to the processor. The processor compares the measured humidity with the set humidity. If the difference between the measured and set humidity exceeds a set threshold, a humidity control signal is generated based on the difference between the set and measured humidity. The humidity controller adjusts the internal humidity of the UV aging test equipment based on the humidity control signal. The temperature calibration probe collects the UV aging test equipment's calibration temperature and transmits it to the processor. If the processor determines the difference between the calibration temperature and the measured temperature exceeds 0.2°C, a temperature deviation signal is generated. The humidity calibration probe collects the UV aging test equipment's calibration humidity and transmits it to the processor. If the processor determines the difference between the calibration humidity and the measured humidity exceeds 2%RH, a humidity deviation signal is generated. The heater's built-in insulation resistance meter measures the insulation resistance between the heater housing and ground. If the insulation resistance is less than 30M ohms, the UV aging test equipment indicates that the heater is in an unhealthy state and may be faulty, displaying an alarm.

[0062] UV aging test equipment incorporates UVC-band ultraviolet light, which ranges from 200nm to 275nm and peaks at 254nm. This addition of UVC-band ultraviolet radiation, in addition to the UVA and UVB bands, allows for artificial accelerated aging testing of polymer materials facing new failure risk factors. The UV aging test equipment can be configured with three light source types: UVA, UVB, and UVC. The equipment can be configured with a corresponding irradiance probe based on the light source type. The UV aging test equipment integrates remote monitoring and data transmission, enabling networking of test data and supporting remote monitoring and control. Monitoring information includes irradiance intensity curves, blackboard temperature curves, relative humidity curves, and the operating status of various equipment components and the health status of the equipment. Control functions include basic operating commands such as starting and stopping the equipment, setting test methods, as well as manufacturer-operated functions such as equipment calibration and debugging. The UV aging test equipment also offers remote assistance for faults and calibration. The UV aging test equipment's operating parameter curves and data records are uploaded to the cloud in real time, providing traceable test data. Users can remotely monitor the entire device using a mobile app and computer-based device control software. Remote control and early warning shutdown of the device enable timely detection of equipment problems and faults, improving safety.

[0063] The UV aging test equipment is mainly upgraded and expanded to address the problem that current UV aging chambers do not have UVC band short-wave ultraviolet for aging test chambers, so that a single device can support the light aging needs of three bands: UVA, UVB and UVC. At the same time, it meets the aging life assessment of polymer materials themselves using UVC short-wave irradiation disinfection methods generated in public health disinfection. The UVC band simulates the mid-wave ultraviolet radiation of the solar spectrum outside the atmosphere, so this application can also perform artificial accelerated aging tests for life assessment of aerospace materials. The UV aging test equipment has a remote monitoring function, which improves the overall information level of the equipment. The irradiance curve, blackboard temperature curve, relative humidity curve and other equipment information are uploaded to the cloud platform synchronously, and can be viewed and monitored by mobile phones and computers, improving the remote management capabilities of the equipment. The UV aging test equipment can quickly solve fault problems and calibration problems. The laboratory structure change function can be used to test fluid materials and building materials silicone sealants and other polymer materials that are clearly required to use horizontal UV aging in current standards. It combines the trapezoidal structure and the horizontal structure to meet various standard requirements. UV aging test equipment offers new wavelength irradiation capabilities, expanding the irradiation range and anticipating new standard requirements. This allows for preemptive lifespan assessment of polymer materials requiring UVC disinfection, thereby reducing the risk of failure. UV aging test equipment can also be used to assess the lifespan of aerospace materials, meeting military and aerospace standards for welders. UV aging test equipment also features bidirectional data transmission from the device to a cloud platform, uploading core control parameters and curves to a cloud storage platform in real time. Users can access these data online via mobile phones or computers, enabling remote data management of the UV aging test equipment. UV aging test equipment not only improves the timeliness of device data management but also enables remote control, reducing the economic losses and other risks associated with equipment failures when no one is on-site. UV aging test equipment can promptly identify and resolve faults, reducing resource waste caused by these issues. The internal structure conversion function of the UV aging test equipment can convert the original trapezoidal UV aging test equipment and horizontal UV aging test equipment into the same device, thereby improving the availability of the equipment, meeting the standard requirements of the two types of UV aging test equipment, and reducing the equipment cost.

[0064] The test method settings for UV aging test equipment include selecting the light source type, irradiance intensity, blackboard temperature, relative humidity, test segment types, and total test time. The light source type can be selected from UVA, UVB, or UVC; the test segment types can be selected from light, darkness, condensation, or rainfall. The UV aging test equipment is calibrated for three parameters: irradiance intensity, blackboard temperature, and relative humidity. The device's irradiance can be calibrated using the CRU00 UV light source calibrator or a traceable UV light calibration instrument. The calibrator's irradiance probe is placed on the same surface as the device's sample and close to the device's irradiance probe. The irradiance energy emitted by the UV light source is received simultaneously by both devices. After the calibrator's irradiance signal is transmitted to the processor's calibration module, the processor makes corrections based on the deviation between the device's own irradiance and the calibrated irradiance until the device's irradiance value matches that of the calibrator. The processor then saves the calibrated irradiance gain value as a benchmark. Similarly, blackboard temperature and relative humidity are calibrated using the same method. Once the user has placed the calibrator, calibration can be performed remotely via the manufacturer's authorization or automatically via the processor. Commissioning the UV aging test equipment involves performing basic functional operations on the equipment, primarily testing the integrity of the input and output functions of the equipment's core components. Remote assistance for faults and calibration is provided during the test. The equipment's operating parameter change curves and data records are uploaded to the cloud in real time, providing users with authentic and traceable test data records. Use the mobile phone APP and computer device control software to remotely monitor the overall information of the equipment. You can also remotely control the equipment and shut down the equipment with early warning. The equipment has an automatic protection function during early warning shutdown. When the studio door is opened during ultraviolet irradiation, the system will automatically shut down to prevent radiation damage to personnel; when the studio water temperature detected by the equipment is too high, for example, the water temperature exceeds 80°C, to prevent the water from boiling and causing damage to the equipment and personnel, the system will automatically shut down; when the core control parameters of the equipment, such as irradiance, blackboard temperature or relative humidity, deviate too much, to prevent the true effectiveness of the test from deviating, the equipment will display an alarm message and shut down after 20 minutes.
