Description

Technical Field

[0001] This invention belongs to the technical field of umbrella integration with multi-band sunlight monitoring technology, specifically involving a spectrally adapted sunlight management umbrella system that determines sunlight management quantities based on the spectral parameters of a replaceable optical film umbrella surface and target band radiation data. Background Technology

[0002] Traditional sun umbrellas primarily rely on the umbrella surface to physically block sunlight, reducing the impact of sun exposure on the human body. With advancements in materials technology and optical thin-film technology, umbrella surface materials with specific spectral modulation functions are increasingly being used, such as those with high ultraviolet (UV) blocking properties and those selectively transmitting portions of visible or blue light. Users can choose umbrella surfaces with different optical properties to achieve differentiated sunshade, sun protection, or light transmission effects based on different environments and usage needs.

[0003] In existing technologies, some umbrellas employ replaceable canopy structures, but these typically focus only on changing the appearance, color, or structure, without using the multi-band spectral transmittance characteristics of different canopies as a parameter basis for interpreting monitoring data and managing sunlight. On the other hand, canopies with ultraviolet, visible, or near-infrared modulation functions usually only provide passive shading, lacking a management mechanism that links with target band radiation data.

[0004] Furthermore, while some existing smart umbrellas are equipped with radiation sensors, they typically use fixed thresholds based solely on ultraviolet data from a single environment. They fail to consider the spectral parameters of the currently installed umbrella surface to determine the user's actual exposure, reduction in light blocking, or heat load in the ultraviolet, blue, visible, near-infrared, or infrared bands. When different umbrella surfaces are used, the fixed data interpretation methods and management strategies are difficult to adapt to the actual spectral characteristics of the umbrella surface.

[0005] Therefore, existing technologies still lack a technical solution that limits the carrier to an umbrella system, retains a replaceable optical film umbrella surface and spectral parameter set, and can determine the amount of sunlight management based on the target band radiation data and the current umbrella surface spectral parameters, and then implement display, reminder, threshold or power consumption management. Summary of the Invention

[0006] To address the problems in existing technologies where replaceable optical film umbrella surfaces and sunlight monitoring are separate, and the monitoring results are not interpreted in conjunction with the current umbrella surface spectral parameters, this invention provides a spectrally adapted sunlight management umbrella system.

[0007] The system takes the spectral parameters of the currently installed optical film umbrella surface and the target band radiation data collected by the optical radiation sensing component as input to determine at least one physical daylight management quantity, and implements display, reminder, threshold or power consumption management based at least on the daylight management quantity.

[0008] The present invention adopts the following technical solution: A spectrum-adaptive solar management umbrella system includes an umbrella body, at least two replaceable optical film umbrella surfaces, a solar management terminal installed on the umbrella body, and a parameter storage unit.

[0009] Each optical film umbrella surface has different preset spectral transmission characteristics and is detachably installed on the umbrella ribs; the sunlight management terminal includes a light radiation sensing component, a processor, a display or indicator device, and a power module; the parameter storage unit provides a set of spectral parameters corresponding to each umbrella surface type.

[0010] The processor acquires the type information of the currently installed umbrella surface, calls the corresponding spectral parameters, determines the daylight management level of the target band based on the target band radiation data collected by the optical radiation sensing component and the spectral parameters, and adjusts at least one of the following based on the daylight management level: display mode, reminder strategy, reminder threshold, or power consumption state switching condition. The target band includes at least one of ultraviolet, blue light, visible light, near-infrared, or infrared.

[0011] The sunlight management quantities referred to in this invention are divided into physical sunlight management quantities and evaluative sunlight management quantities. Physical sunlight management quantities include at least one of the following: actual exposure intensity of the target wavelength band, environmental target wavelength band intensity, target wavelength band intensity behind the membrane or under the umbrella, cumulative exposure dose, blocking amount, transmittance ratio, heat load index, or equivalent exposure intensity corrected for spectral parameters. Evaluative sunlight management quantities are mapped from physical sunlight management quantities and include at least one of the following: risk level, threshold level, alert level, power consumption state switching parameters, or management strategy parameters. The sunlight management quantities in an independent technical solution at least include the aforementioned physical sunlight management quantities.

[0012] Type information can be obtained through at least one of the following methods: automatic identification, manual user selection, mobile terminal input, or preset binding relationship. Automatic identification can use QR codes, color codes, mechanical codes, magnetic codes, resistive codes, contact codes, RFID tags, or NFC tags; server synchronization is only used for synchronizing spectral parameter sets or umbrella model libraries.

[0013] Optical radiation sensing components may include at least one of the following: ultraviolet sensor, UVA sensor, UVB sensor, blue light sensor, near-infrared sensor, multi-channel spectral sensor, filter array and photodiode combination, miniature spectrometer or illuminance sensor.

[0014] In one dual-sensor implementation, the first optical radiation sensing unit on the outer side of the umbrella measures the ambient target wavelength intensity E. env The measured intensity E behind the membrane by the second light radiation sensing unit on the underside of the umbrella. under Based on this, the processor determines the reduction in obstruction ΔE=E env -E under Through ratio T bandCumulative actual exposure dose D actual Or avoid exposure to dose D avoided At least one of them.

[0015] In a time-division multiplexing implementation at a single sensing location, the processor uses the data collected in the unopened parachute state as E. env The data collected in the parachute-open state will be used as E under And pair the data before and after the opening and closing states. Only when E is unavailable env When calculating actual values, E is estimated based on umbrella surface transmittance, calibration correction factor, installation location, angle of incidence, or historical data. env .

[0016] When the umbrella identification mark is not successfully identified or the type information is not obtained, the processor enters the unknown umbrella mode. It uses the most unfavorable spectral transmission parameter in the stored spectral parameter set or the preset minimum protection parameter to determine the solar management amount. Before the user confirms the umbrella mode, it stops outputting the protection conclusion based on the umbrella spectral parameters and only displays the measured target band radiation intensity, prompting the user to confirm or select the umbrella mode.

[0017] When installed on the umbrella, the sunlight management terminal can determine the level of sunlight exposure events based on at least one of the following: the spectral parameters of the current umbrella surface, the radiation intensity of the target band, the rate of change of radiation intensity, or the duration of the event. It can also adjust the switching conditions between low power consumption mode, local display mode, and communication reminder mode.

[0018] The spectral parameter set may include transmittance or blocking rate, T(λ), band integral or weighted transmittance, cutoff wavelength, installation location, incident angle or aging correction factor for each target band. The spectral parameter set can be obtained through spectral testing or calibration during production, factory testing, user retesting or terminal calibration.

[0019] The sunlight management terminal can be removed from the umbrella handle and held by the user or placed on a table for inspection, charging, calibration, or data reading; this detachable state does not change the limitation of the umbrella system carrier of the present invention.

[0020] The present invention also provides a sunlight management method for the spectrally adapted sunlight management umbrella system, and a sunlight management device for the umbrella system. The system, method, and device all share the following specific technical features: determining at least one physical sunlight management quantity based on the spectral parameters of the currently installed optical film umbrella surface and target band radiation data collected by a light radiation sensing component, and implementing display, reminder, threshold, or power consumption management based at least on the sunlight management quantity.

[0021] The beneficial effects of this invention are as follows: The spectral parameters of the currently installed replaceable optical film umbrella surface are used together with measured radiation data of the target band to determine the physical daylight management quantity, enabling the display, reminders, thresholds, and power consumption management to be adapted to the actual spectral characteristics of the umbrella surface; the multi-band scheme simultaneously covers ultraviolet, blue light, visible light, near-infrared, or infrared light, helping to reduce false alarms and missed alarms caused by using fixed thresholds; the combination of automatic identification and manual selection, and the conservative evaluation, suspension of protection conclusions, and confirmation prompts based on the most unfavorable parameters of unknown umbrella surface modes, reduce the possibility of strategy mismatch due to identification errors; the correspondence between the replaceable optical film umbrella surface and the spectral parameter set facilitates the formation of a sustainable maintenance, calibration, and upgrade system for umbrella products.

[0031] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that this disclosure will be more comprehensive and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art.

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments, but the scope of protection of the present invention is not limited to the following embodiments. Those skilled in the art can make equivalent changes to the specific implementation structure and connection methods without departing from the concept of the present invention.

[0033] like Figures 1-8 As shown, the spectrally adapted solar management umbrella system of this embodiment includes an umbrella body, at least two replaceable optical film umbrella surfaces, a solar management terminal installed on the umbrella body, and a parameter storage unit.

[0034] The umbrella body includes the umbrella pole, umbrella ribs, umbrella handle, and opening and closing mechanism. Each optical film surface has different preset spectral transmittance characteristics and is installed to the umbrella ribs via a quick-release connection structure.

[0035] The solar management terminal includes a light radiation sensing component, a processor, a display or indicator device, a power module, and a communication module. The processor obtains the type information of the currently installed umbrella surface, retrieves the corresponding spectral parameters from the parameter storage unit, and determines the solar management amount by combining it with the target band radiation data.

[0036] The target wavelength includes at least one of ultraviolet, blue light, visible light, near-infrared, or infrared. The solar management quantity includes at least a physical solar management quantity and may further include an evaluative solar management quantity mapped from the physical solar management quantity; the mapping is determined based on at least one of the target wavelength irradiance, cumulative exposure dose, exposure time, and spectral transmittance parameters of the current optical film umbrella surface.

[0037] Physical daylight management quantity can be E env E under ΔE, D actual D avoided T band Exposure duration, heat load index, or equivalent exposure intensity; evaluative daylight management parameters can be risk level, threshold level, alert level, power consumption status switching parameters, or management strategy parameters.

[0038] Umbrella type information can be obtained through automatic identification, manual user selection, mobile terminal input, or preset binding relationships. Spectral parameter sets can be pre-stored locally or synchronized by the mobile terminal or server; the server is not used as a method to obtain the current umbrella type information.

[0039] When type information is not obtained, the processor enters unknown umbrella mode, uses the most unfavorable spectral transmission parameter or the preset minimum protection parameter to determine the amount of sunlight management, pauses the output of protection conclusions based on umbrella spectral parameters, and only displays the measured target band radiation intensity and prompts the user for confirmation.

[0040] When installed on the umbrella, the sunlight management terminal performs display, reminders, threshold management, or power consumption management based at least on the aforementioned sunlight management parameters. After being removed from the umbrella handle, the terminal can be held in hand or placed on a table for inspection, charging, calibration, or data reading.

[0041] Example 1: Basic Structure of a Modular Solar Management Umbrella System like Figures 1 to 2 As shown in the figure, this embodiment presents the basic components of a modular solar management umbrella system.

[0042] The umbrella body includes the umbrella shaft, multiple ribs (such as 8 or 16 fiberglass / carbon fiber ribs), the handle, and the opening and closing mechanism (such as a manual push-pull type or an automatic spring type). The umbrella structure can be a straight-handle umbrella or a folding umbrella.

[0043] The system is equipped with at least two replaceable optical film umbrella surfaces. Each optical film umbrella surface includes at least one transparent polymer base film and a spectral modulation structure for controlling the transmission characteristics of a target optical band. The spectral modulation structure may include a spectral functional agent dispersed in the transparent polymer base film, and / or a spectral modulation layer formed on at least one side surface of the transparent polymer base film. The spectral modulation layer may be formed by a wet coating process, a dry deposition process, or a combination thereof, and is configured to absorb, reflect, scatter, interfere, or selectively transmit at least one of the ultraviolet, blue, visible, near-infrared, or infrared bands, thereby giving different optical film umbrella surfaces different preset spectral transmission characteristics.

[0044] The transparent polymer base film may include at least one of PVC, EVA, PC, TPU, PET, PA, PE, PP, SEBS polymer films or composite films thereof. The spectral functional additives may include ultraviolet absorbers, blue light absorbers, near-infrared absorbers, infrared absorbers, inorganic oxide particles, metal oxide particles, organic dyes, pigments, light stabilizers or combinations thereof. The spectral modulation layer may include an absorption layer, a reflection layer, a scattering layer, a dielectric layer, a metal layer, a metal oxide layer, a multilayer optical interference film or combinations thereof.

[0045] For example: • Umbrella Surface A – High UV Barrier Umbrella Surface: Using a transparent or semi-transparent polymer base film as the substrate, and forming a UV spectral modulation structure through at least one of the following methods: incorporating or dispersing UV-absorbing spectral functional additives into the substrate layer or coating; forming a wet coating layer containing UV absorbers on at least one side of the substrate layer; or forming a dry deposition layer with UV reflection or interference modulation effects on at least one side of the substrate layer. Umbrella Surface A has a corresponding first set of spectral parameters, which includes at least one or more of UVA band transmittance, UVB band transmittance, and visible light band transmittance, determined based on spectral data obtained during the production process, factory testing, or calibration testing.

[0046] • Umbrella Surface B – Medium UV Blocking Umbrella Surface: It has UVA, UVB and visible light transmission characteristics that are different from those of Umbrella Surface A. The specific parameters are subject to the measured calibration data.

[0047] • Umbrella surface C -- High visible light transmittance umbrella surface: Compared to umbrella surface A, it has a higher visible light transmittance while retaining the preset ultraviolet blocking capability. Specific parameters are subject to actual measurement and calibration data.

[0048] • Umbrella Surface D – Blue Light Selective Transmission Umbrella Surface: While maintaining the preset ultraviolet blocking capability, it selectively transmits specific blue light sub-bands. Specific parameters are subject to actual measurement and calibration data.

[0049] Each optical film canopy is detachably connected to the canopy ribs at the end of the canopy ribs via a connecting structure (such as the quick-release connecting structure described in this manual).

[0050] The solar management terminal is installed on the umbrella handle or pole via a handle clip connector or pole connector. The terminal contains a light radiation sensor, a processor, a display or indicator device, a wireless communication module, and a power module. When installed on the umbrella, it can display the measured target band radiation intensity, solar management level, and current umbrella canopy mode.

[0051] Example 2: Umbrella Type Identification and Spectral Parameter Retrieval like Figures 4 to 5 As shown, this embodiment describes in detail the method for identifying umbrella types and the mechanism for calling spectral parameters.

[0052] 2.1 Umbrella Identification Markings Each optical film umbrella surface is equipped with a unique identification mark at the time of manufacture. The implementation methods for this identification mark include, but are not limited to: (a) QR code: A QR code is printed on the inner edge of the umbrella surface (such as where the label is sewn) or on the umbrella beads. The QR code contains information such as the umbrella surface model and spectral characteristic parameter index. Users can scan the code using their mobile phone camera, and the mobile APP will send the umbrella surface type to the solar management terminal or directly access local parameters.

[0053] (b) Color coding: Different color combinations (such as 2-3 color rings) are set on the connecting piece / ring that connects each umbrella canopy to the umbrella rib. The color coding can be recognized by taking a picture with the APP installed on the terminal or mobile phone; the terminal can also read the color code by its built-in color sensor.

[0054] (c) NFC tag: An NFC tag (NTAG213, etc.) is embedded in the umbrella canopy connector. The tag stores the umbrella canopy type and spectral parameter values ​​or parameter indexes. The terminal or mobile phone can read the tag by bringing it close.

[0055] (d) Mechanical coding: Mechanical protrusions or grooves (i.e., the mechanical coding structure) are set at different positions / numbers on the connecting pieces of each umbrella surface, which are used in conjunction with micro switches on the terminal or umbrella rib connecting seat to read.

[0056] (e) Resistance coding / electrical contact coding: Different resistance values ​​or electrical contact combinations are set on the umbrella-shaped connecting piece, and the terminal reads the resistance value or level combination.

[0057] 2.2 Spectral Parameter Set The system (terminal storage or mobile app database) stores a set of spectral parameters corresponding to each umbrella type. The spectral parameter set contains at least some or all of the following parameters: UVA band information: Average transmittance (T) in the 315-400nm band UVA ) or barrier ratio (R UVA =1-T UVA ); UVB band information: Average transmittance (T) in the 280-315nm band UVB ) or barrier rate; Blue light band information: Average transmittance (T) of 400-500nm (or specific sub-bands such as 450-480nm) Blue ) or barrier rate; Visible light band information: Average transmittance (T) of 400-700nm VIS ); Near-infrared band information: Average transmittance (T) in the 700-2500nm (or 700-1100nm) band. NIR (or infrared blocking rate); Correction factor: A correction factor for the difference between the actual UV attenuation received by the sensor and the theoretical attenuation when the terminal is installed under an umbrella (this can be calibrated experimentally).

[0058] 2.3 Determination and Management Actions of Daylight Management Quantity The processor determines the solar management amount based on the current spectral parameters of the umbrella surface and the target band radiance data. The solar management amount may include the ambient target band intensity E. env Under-umbrella strength Eunder The reduction in barrier depth ΔE = E env -E under Cumulative actual exposure dose D actual Avoid exposure to dose D avoided Through ratio T band At least one of the following: exposure duration, heat load index, or equivalent exposure intensity.

[0059] In the dual-sensor implementation, the first optical radiation sensing unit is disposed on the outer side of the umbrella surface and measures E. env The second optical radiation sensing unit is located on the underside of the umbrella and E is measured. under The processor can pair two sets of data according to the same time window and target band, and calculate ΔE and T. band and E under D is obtained by integrating ΔE and ΔE over the exposure duration. actual and D avoided .

[0060] In the time-division multiplexing implementation at a single sensing location, the processor identifies the umbrella opening state based on mechanical switches, inertial measurement units, sudden changes in light intensity, or manual confirmation from the user. The measurement value in the unopened state is used as E. env The measurement value in the open parachute state is taken as E. under The processor pairs data from adjacent time windows before and after umbrella deployment. This time-division measurement is the primary implementation method for single-sensor location.

[0061] When unavailable E data cannot be obtained due to factors such as installation location, rapid weather changes, or measurement timing. env When measuring actual values, the processor can estimate E based on the target band transmittance of the current umbrella surface, preset calibration correction coefficients, installation position, incident angle, or historical data. env The estimation serves as a supplementary approach when measured data is unavailable.

[0062] The relevant calculations can be performed individually or collaboratively by the local processor of the solar management terminal, the mobile terminal, or the cloud server. The solar management terminal can exchange information such as opening / closing status, umbrella type, target band radiation data, and solar management amount with the mobile terminal via Bluetooth or NFC.

[0063] The processor generates display or alert information based at least on the determined physical daylight management parameters, and can map these to risk levels, threshold levels, alert levels, power consumption state switching parameters, or management strategy parameters. Transmittance correction or preset correction coefficient compensation is one way to determine the equivalent exposure intensity, but not the only calculation path.

[0064] For example, the display interface can simultaneously present the measured E under Estimated or measured E env ΔE, Dactual D avoided One or more of the following: exposure duration; the alert threshold is set based on physical daylight management and current umbrella spectral parameters to reduce the mismatch between the fixed threshold and the actual transmittance characteristics of the umbrella.

[0065] When installed on the umbrella, the sunlight management terminal can determine the level of sunlight exposure events based on the current spectral parameters of the umbrella surface, the radiation intensity of the target band, the rate of change of radiation intensity, or the duration of the event, and adjust the switching conditions between low power consumption mode, local display mode, and communication reminder mode.

[0066] Example 3: Synergy between manual selection and automatic recognition of umbrella pattern like Figure 6 As shown, in addition to automatic recognition, the system also supports users to manually select the currently installed umbrella type (umbrella mode) through the terminal operation interface or mobile APP.

[0067] The manual selection method is applicable to the following scenarios: (1) the umbrella surface identification mark is dirty or damaged and cannot be identified; (2) the user temporarily uses a compatible umbrella surface without identification mark; (3) the user wants to preview the reminder strategy under different umbrella surface modes.

[0068] Consistency verification mechanism: When the terminal simultaneously obtains both the automatically identified umbrella type information and the user-selected umbrella mode, the processor performs a consistency check: If the two are consistent, the corresponding spectral parameter set should be used directly. If the two results are inconsistent, the terminal will output a verification prompt. This prompt can be displayed by flashing a specific icon, via an app push notification, or by emitting a specific beeping sound. The prompt reminds the user to confirm the current actual umbrella installation status, and the user can choose to accept the automatic recognition result or retain the manual selection.

[0069] Unidentified handling: When the solar management terminal fails to identify the umbrella type or fails to acquire type information, the processor enters an unknown umbrella mode. In this mode, the processor uses the most unfavorable spectral transmission parameter from the stored spectral parameter set or a preset minimum protection parameter to determine the solar management level. Before the user confirms the umbrella mode, the processor stops outputting protection conclusions based on the umbrella spectral parameters and only displays the target band radiation intensity collected by the optical radiation sensor. Simultaneously, the processor prompts the user to confirm or select the umbrella mode via the display screen or mobile terminal. After user confirmation, the processor retrieves the corresponding spectral parameters and resumes the corresponding solar management output.

[0070] Example 4: Installation, Removal and Maintenance of Sunlight Management Terminal like Figure 3As shown, the sunlight management terminal is installed on the umbrella body via the umbrella handle clip connector or the umbrella pole plug connector, and performs sunlight management in combination with the current spectral parameters of the umbrella surface when installed.

[0071] When charging, checking, calibrating, or reading data is required, the user can remove the solar management terminal from the umbrella handle connector and hold it in their hand, or place it on a table. After completing the operation, reinstall the terminal onto the umbrella and confirm the current umbrella mode.

[0072] After the terminal is reinstalled, the processor obtains the type information of the currently installed umbrella surface and calls the corresponding spectral parameter set; if the type information is not obtained, it enters the unknown umbrella surface mode and prompts for confirmation in the aforementioned manner.

[0073] Example 5: Multi-user scenarios and umbrella group management like Figures 6 to 7 As shown, this embodiment describes system expansion in a home or group use scenario.

[0074] A family or group can own one or more umbrellas, various optical film canopies, and one or more daylight management terminals. Each user can manage umbrella canopy preferences and target wavelength exposure history by binding a terminal ID to a mobile device.

[0075] After a user installs a sunlight management terminal onto an umbrella, the system obtains the type of the currently installed umbrella surface, determines the sunlight management amount by combining the corresponding spectral parameters and target band radiation data, and can adjust the reminder presentation method according to the user's settings.

[0076] The umbrella canopy is interchangeable between compatible umbrella bodies. The system records the cumulative usage time, cumulative number of deployments, and cumulative sunlight exposure of the umbrella canopy, and uses an aging correction factor to prompt for inspection or replacement.

[0077] In some implementations, the daylight management terminal may include one or more of the following: a data acquisition unit, a data processing unit, a data display unit, a data storage unit, a wireless communication unit, and / or an alert output unit.

[0078] The data acquisition unit is used to acquire target band radiation data, umbrella type information, ambient light information, location information and / or user input information; The data processing unit is used to perform daylight management calculation, umbrella surface identification, consistency verification, unknown umbrella surface mode control, reminder strategy generation and / or historical data analysis. The data display unit is used to display the target band radiation intensity, umbrella type, physical daylight management amount, evaluative daylight management amount and / or reminder information; The reminder output unit can output reminder information through vibration, buzzer, light prompts, voice prompts and / or push messages from mobile terminals.

[0079] The relevant data processing can be completed by the solar management terminal itself, mobile terminal, cloud server, or a combination thereof.

[0080] In some implementations, the system can continuously record the exposure history of the target band.

[0081] The recorded content may include one or more of the following: time information, geographical location information, target band radiation data, umbrella type, daylight management amount, usage duration, and / or user response records.

[0082] One or more external devices can store, analyze, and compare data collected at different time periods to generate user UV exposure trend information, umbrella usage habit information, and / or protective behavior analysis results.

[0083] The trend information provided may be used as a reference for users to manage their daily sun protection, but should not be used as a basis for medical diagnosis.

[0084] In some implementations, the system may also include environmental parameter detection functionality.

[0085] The environmental parameters may include one or more of the following: temperature, humidity, illuminance, air pressure, wind speed, rainfall status, and / or air quality parameters.

[0086] The sunlight management terminal may also include an environmental parameter sensor for collecting temperature, the environmental parameter sensor being independent of the light radiation sensing component.

[0087] The processor can determine the alert strategy based on environmental parameters and umbrella surface spectral parameters.

[0088] For example, when the temperature is high and the radiation intensity of the target band is high, the alert level can be increased; when the radiation intensity of the target band is low, the alert frequency can be reduced.

[0089] In this embodiment, the spectral parameter set can be obtained through spectral testing or calibration during the production, factory inspection, user retesting, or solar management terminal calibration of the optical film umbrella surface.

[0090] For production or factory calibration, spectrophotometers, radiometers, integrating sphere spectral testing systems, or photoelectric detection systems with switchable filters can be used. The test wavelength range covers the target wavelength band to be managed, such as the ultraviolet band of 280-400nm, the blue light band of 400-500nm, the visible light band of 400-700nm, and the near-infrared band of 700-2500nm; for infrared thermal load management, it can be extended to the corresponding infrared band.

[0091] The test object can be a sample with the same substrate layer, spectral modulation structure, film layer sequence, thickness range, and processing conditions as the actual optical film umbrella surface, or it can be a local area of ​​the actual optical film umbrella surface. The test location can include the top area of ​​the umbrella, the middle area of ​​the umbrella surface, the edge area of ​​the umbrella, or a combination thereof, and can be carried out by sampling test or in-situ test method.

[0092] During spectral testing, the transmission spectrum, reflectance spectrum, or radiation response data of the target wavelength band can be measured under normal incident conditions and one or more preset tilted incident angles. The target wavelength band may include at least one of UVA, UVB, blue light, visible light, near-infrared, or infrared bands. During testing, a sample-free optical path, a standard transmittance film, a standard reflectance film, a standard white plate, or a metrologically calibrated reference sample can be used as a reference standard, and the testing instrument can be calibrated for dark current, baseline, wavelength, or irradiance.

[0093] Based on the test results, at least one of the following can be determined: wavelength-dependent transmittance T(λ), target band average transmittance, band integral transmittance, weighted transmittance, blocking rate, cutoff wavelength, incident angle correction factor, installation position correction factor, or aging correction factor. For the same type of optical film umbrella surface, the test results from multiple test locations, multiple samples, or multiple batches can be statistically processed to form a spectral parameter set corresponding to the umbrella surface type information. The spectral parameter set can be associated with umbrella surface identification, umbrella surface model, or parameter version information and can be accessed by a solar management terminal, mobile terminal, or server.

[0094] During user retesting or terminal calibration, under conditions of known radiation sources or parallel measurements with a reference instrument, the target band data on the outer and underside of the umbrella can be compared to update the position correction coefficient, sensor response correction coefficient, or aging correction coefficient. Updated values ​​can be saved locally and associated with parameter versions on the mobile terminal or server.

[0095] The spectral parameter set can be pre-stored in the daylight management terminal or mobile terminal, or it can be synchronized from the server. Server synchronization is used to update the spectral parameter set or the umbrella model library; the type information of the currently installed umbrella is still obtained through automatic identification, manual selection by the user, input from the mobile terminal, or preset binding relationships.

[0096] In this embodiment, the system records the cumulative usage time, cumulative number of deployments, cumulative ultraviolet exposure, and / or service life of the umbrella surface.

[0097] The processor estimates the current protective performance of the umbrella canopy based on a preset aging model.

[0098] When the transmission or blocking performance of the target band, as determined by actual measurement or aging model, reaches the preset maintenance threshold, the system outputs a maintenance prompt or replacement prompt.

[0099] The prompt may include: It is recommended to test the umbrella canopy performance; It is recommended to replace the umbrella canopy; Recommended new umbrella models; This indicates that the spectral modulation performance of the current umbrella surface may change.

[0100] In some implementations, the umbrella surface may be equipped with a lifespan identification code, and the system associates the identification code with its manufacturing date and design lifespan information.

[0101] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
