The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0025] Embodiment 1

[0026] In this embodiment, an electromagnetic shielding window with adjustable light transmittance is provided, and the electromagnetic shielding window includes:

[0027] A dimming layer and an electromagnetic shielding layer, wherein the dimming glass adjusts the transmittance of the electromagnetic shielding window by passing voltage, and the electromagnetic shielding glass is used to shield external electromagnetics.

[0028] As some embodiments, Figure 4 As shown, the dimming glass includes a light-transmitting substrate, a first transparent conductive layer, an ion storage layer, an electrolyte layer, an electrochromic layer, and a second transparent conductive layer in sequence; the electromagnetic shielding layer adopts an electromagnetic shielding glass, wherein the electromagnetic shielding glass includes a first transparent glass, a shielding layer, and a second transparent glass arranged in sequence, wherein the second transparent conductive layer of the dimming layer is bonded to the electromagnetic shielding glass through an adhesive layer, and fixed by a related fixing device to form an electromagnetic shielding window.

[0029] As some embodiments, in the dimming layer, the translucent substrate is made of tempered glass or inorganic glass, wherein the inorganic glass can be selected from soda-lime glass, high-aluminum glass, borosilicate glass, etc., the first transparent conductive layer and the second transparent conductive layer can independently use ITO (indium tin oxide) conductive layer, FTO (fluorine-doped tin oxide) conductive layer or AZO (aluminum-doped zinc oxide) conductive layer, the ion storage layer is made of nickel oxide ion storage layer or V2O5 (vanadium pentoxide) ion storage layer, the electrolyte layer is made of lithium manganate electrolyte layer or lithium titanate electrolyte layer, the electrochromic layer is made of tungsten trioxide electrochromic layer or manganese trioxide electrochromic layer, and the dimming layer is formed by depositing different materials of corresponding layers on the translucent substrate in sequence through a magnetron sputtering process, and the ratio of the thickness of different layers in the dimming layer is: 1:5:3:7:1.

[0030] As some embodiments, in the electromagnetic shielding layer, the first transparent glass and the second transparent glass are anti-reflection glass, which is formed by coating an anti-reflection film on a glass substrate, and the glass substrate is made of tempered glass or inorganic glass. The shielding layer uses a high-transmittance finished high-temperature adhesive-backed conductive shielding grid PET film, and the high-temperature adhesive-backed conductive shielding grid PET film includes a shielding grid layer, a polyester film, and a high-temperature adhesive layer. A metal layer is formed on the polyester film, and the metal layer is processed into a metal mesh through an etching process and adhesive is attached to the back of the polyester film. The shielding grid layer uses nano-silver parts processed to a wire diameter of 0.01 mm, and the polyester film uses PET material.

[0031] As some embodiments, the second transparent conductive layer of the dimming layer is bonded to the electromagnetic shielding layer through an adhesive layer, and the adhesive layer is bonded using materials such as PVB, EVA, SGP or PVE to form a corresponding adhesive layer to bond the above structure.

[0032] The first transparent conductive layer and the second transparent conductive layer in the dimming layer are connected to a power source, and a voltage is applied across the two ends of the electrochromic layer; under the action of the electric field of the applied voltage, ions migrate into or out of the electrochromic layer, causing the valence of the material in the electrochromic layer to decrease or increase. Before reaching equilibrium, the color of the electrochromic layer will change. After reaching equilibrium, the color change of the electrochromic material becomes stable, so that the transmittance can be adjusted. At the same time, different transmittances can be achieved according to the size of the applied voltage.

[0033] Through the above technical scheme, the present invention provides an electromagnetic shielding window with adjustable transmittance, which performs electromagnetic shielding through an electromagnetic shielding layer and uses a dimming layer to adjust the transmittance. It can realize the function of adjustable transmittance based on the electromagnetic shielding function, and can reduce the influence of the electromagnetic corresponding environment. At the same time, it can reduce the influence of external light and protect privacy at a specific time by adjusting the relevant content of the transmittance.

[0034] Embodiment 2

[0035] like Figure 1-2 As shown, in order to better realize the above technical solution of the present invention, the present invention also provides an intelligent control system based on the electromagnetic shielding window with adjustable light transmittance for the electromagnetic shielding window with adjustable light transmittance.

[0036] The accusation system includes a sensor module, an adjustment module and a storage module.

[0037] The sensing module, adjustment module and storage module are connected in sequence, the sensing module is used to obtain environmental information, the adjustment module is used to obtain input instructions, generate corresponding adjustment instructions according to the input instructions and environmental information, adjust the transmittance of the dimming layer according to the adjustment instructions, and the storage model is used to store environmental information, input instructions and adjustment instructions.

[0038] In the process of adjusting the electrochromic material, the greater the voltage applied to the electrochromic layer, the more obvious the change in color depth, and thus the lower its transmittance. However, when the applied voltage is large, its power consumption will also increase, and the life of the dimming layer will also decrease rapidly. Therefore, the dimming layer is adjusted through the intelligent control system to reduce the applied voltage of the dimming layer as much as possible. The daily concealment of the display information of the equipment or environment is guaranteed on the basis of lower voltage or lower power. When necessary, the transmittance is adjusted by inputting commands to clarify the display content of the equipment. At the same time, there is no need to open the electromagnetic protection casing of the relevant equipment to prevent electromagnetic leakage.

[0039] As some embodiments, the sensing module uses a light sensor, and the environmental information is light information, wherein the light sensor is arranged in a vicinity of the electromagnetic shielding window, wherein the vicinity is the external environment of the device protected by the electromagnetic shielding window, and does not affect the light transmittance of the electromagnetic shielding window on both sides, up and down or other positions, and the light sensor is used to collect the light intensity around the electromagnetic shielding window in real time to provide corresponding feedback to the subsequent adjustment module, so as to make corresponding adjustments to the light transmittance of the electromagnetic shielding window.

[0040] As some embodiments, Figure 3 As shown, the adjustment module mainly adjusts the transmittance of the electromagnetic shielding window in real time through the light intensity around the electromagnetic shielding window, ensuring that a smaller voltage is used as much as possible to ensure the higher concealment of the equipment protection information, wherein the adjustment module mainly uses a corresponding adjustment model for the transmittance of the electromagnetic shielding window, wherein the input of the adjustment model is the corresponding environmental information, and the output is the corresponding adjustment instruction, wherein the adjustment instruction sets the voltage size and positive and negative of the first transparent conductive layer and the second transparent conductive layer through the transmittance that needs to be adjusted. The adjustment model may select a fitting model or a more complex deep learning model. When the adjustment model adopts a fitting model, a first-order fitting equation, i.e., a first fitting model, is used. The transmittance is used as the dependent variable, and the environmental information is used as the independent variable. The corresponding value of the transmittance to be adjusted is generated by inputting the current environmental information. The transmittance value is adjusted as needed. A third-order fitting equation, i.e., a second fitting model, is used. The value of the transmittance to be adjusted is used as the independent variable. The voltage magnitudes applied to the first transparent conductive layer and the second transparent conductive layer of the control dimming layer are respectively used as dependent variables. The transmittance to be adjusted is input through two third-order fitting equations to generate the corresponding voltage magnitudes of the first transparent conductive layer and the second transparent conductive layer. The voltage magnitudes include positive and negative values. A positive value indicates the magnitude of the applied positive voltage, and a negative value indicates the magnitude of the applied negative voltage.

[0041] For the first fitting model and the second fitting model, it is first necessary to collect historical manual control data or perform relevant simulations to optimize the first fitting model and the second fitting model. The historical manual control or relevant simulation data are: at different light sizes, in order to reduce the impact of external light on the display of the protective device inside the electromagnetic shielding window, when the electromagnetic shielding window cannot effectively display its content, the electromagnetic shielding window adjusts the transmittance and records the recorded values ​​and external light values, and adjusts different transmittances as needed, and under different input voltages, the corresponding transmittance and voltage values ​​are actually recorded data and simulated recorded data to optimize and generate a fitting model that can effectively characterize the correlation between independent variables or dependent variables. The judgment standard when the content cannot be effectively displayed is obtained based on actual observations of several relevant personnel. The optimized fitting model can be used to directly input the values ​​of the relevant independent variables to obtain the values ​​of the dependent variables, so as to obtain the specific transmittance values ​​and voltage values. The voltage input to the first transparent conductive layer and the second transparent conductive layer can be adjusted by connecting a transformer or a rheostat to the output end of the voltage source through adjustment instructions, adjusting the size of the transformer or the rheostat, or directly adjusting the output voltage of the voltage source without connecting an external adjustment device, so as to achieve real-time adjustment of the transmittance of the electromagnetic shielding window to adapt to the environment in real time.

[0042] As some embodiments, when the adjustment model uses a deep learning model, a neural network model such as a fully connected neural network DNN, a convolutional neural network CNN or a time series neural network LSTM can be used. When using the deep learning model, the correlation between the environmental information and the voltage size of the first transparent conductive layer and the second transparent conductive layer is directly fitted. Specifically, the deep learning model is trained through the above-mentioned historical data or simulation data. When the accuracy reaches a certain requirement, it can be used directly. The nonlinear fitting ability of the deep learning model can more effectively understand the correlation between the environmental information and the voltage size of the first transparent conductive layer and the second transparent conductive layer, so as to effectively regulate it. The fitting model in the adjustment model is used as the basis, and the deep learning model can be selected as an alternative model. When the adjustment model is a deep learning model, only adaptive regulation is performed, or a weighted sum is performed with the output result of the above-mentioned fitting model to output the final adaptive instruction. When input regulation is performed, only the second fitting model in the fitting model is used.

[0043] As some embodiments, the adjustment module in the present invention can also be connected to an external device or an external intelligent terminal, and the corresponding transmittance value is input through the external device or the intelligent terminal to obtain the input instruction, and the setting is performed according to the transmittance value in the input instruction, and the voltage of the first transparent conductive layer and the second transparent conductive layer is adjusted through the above-mentioned second fitting model to adjust the transmittance. In addition to the input instruction, it also includes a timing instruction, wherein the timing instruction includes an adjustment time and a duration for adjusting the transmittance of the input instruction. The specific timing instruction includes the adjustment time and duration. The adjustment time is that at a certain time, i.e., the adjustment time, the transmittance is adjusted to the transmittance corresponding to the input instruction, and the duration is that after the adjustment time, the transmittance is continuously adjusted to the value at a certain time, i.e., the duration. Wherein the priority of the input instruction and the timing instruction is greater than the priority of the adjustment module to automatically adjust the transmittance. After the timing instruction is input, the adjustment model no longer receives environmental information. After setting the input voltage corresponding to the input instruction through the second fitting model, the calculation of the adjustment model is no longer enabled, and the transmittance is directly adjusted to the transmittance corresponding to the input instruction until the duration ends, and the environmental information is received again and the adjustment model is enabled. Through the timing function, the transmittance of the electromagnetic shielding window can be adjusted to a smaller value at a specific time to further observe and view its information.

[0044] A voltage sensor is also provided on the input connection line of the first transparent conductive layer and the second transparent conductive layer. The voltage sensor monitors the input voltage data of the two conductive layers and transmits the data to the storage model through the adjustment model.

[0045] As some embodiments, in a storage module, the above data is stored, and the above content is stored through a related attribute storage architecture, including specific environmental information, input instructions and adjustment instructions, and input voltage data of the first transparent conductive layer and the second transparent conductive layer, and also includes the adjustment model parameters used, including the multi-term coefficients of the fitting model or the model parameters of the deep learning model, wherein a tree storage structure is used for storage, specifically taking the adjustment model control area as the root element, taking the adjustment model as the child element under the root element, taking the model parameters corresponding to the adjustment model as the detailed description of the adjustment model, taking the environmental information, input instructions, adjustment instructions and voltage data at different times as the child elements under the adjustment model, and describing them in detail according to specific numerical values, and marking the input instructions and the corresponding adjustment instructions with external regulation. Through the numerical storage method of the above storage structure, data can be stored in an orderly manner. When a problem occurs, the data at the corresponding time is extracted in real time, and the adjustment model parameters and voltage monitoring data associated therewith are found, so that it can be checked whether there is a problem with its automatic adjustment or whether there is a problem with the input instruction, and the problem of the intelligent control system can be traced in time.

[0046] As some embodiments, a first light sensor is arranged near the internal environment protected by the electromagnetic shielding window. The first sensor receives light that passes through the electromagnetic shielding window and the internal protection environment. The first light sensor is detected by an adjustment module. When the first light sensor is greater than a certain threshold, it is considered that the electromagnetic shielding window cannot effectively shield the information inside the protection environment, that is, the transmittance cannot be adaptively adjusted. In this case, it is considered that there is a problem with the electromagnetic shielding window and an alarm is issued. At the same time, the data of the storage module at the current moment and a certain time interval before is called to check whether there is a problem with the adjustment model and the adjustment instruction. If there is no problem, the voltage data is checked. If the voltage data is different from the adjustment instruction, it is considered that there is a problem with the voltage source or the control device connected to the electromagnetic shielding window. Otherwise, it is considered that there is a problem with the electromagnetic shielding window, and relevant personnel are promptly reminded to replace or repair it.

[0047] Through the above-mentioned intelligent control system, the present invention can collect external environmental information and adjust the transmittance of the electromagnetic shielding window in real time according to the environmental information, so as to achieve effective shielding of the display information of the protection environment or protection equipment. At the same time, the transmittance can also be adjusted regularly according to input instructions, which is convenient for relevant personnel to view the protection information displayed by the equipment while preventing electromagnetic leakage. The data can be further stored through the relevant data storage module to trace and find the system problems in time, which has strong practicality.

[0048] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
