Description

Technical Field

[0001] The present invention relates to the field of optical switching technology, and in particular to a system and method for controlling optical switching. Background Art

[0002] Optically switchable systems and methods are of great significance in modern technology. Such systems achieve efficient switching of light through advanced optical principles and precise control methods. Especially in the smart window industry, they can automatically adjust transparency according to changes in the external environment, thereby achieving energy saving, privacy protection and optimization of indoor comfort.

[0003] Existing optical switching systems are typically electrochromic systems, which change the oxidation state of the material by applying an electric field, thereby adjusting the transmittance of visible light and infrared light. However, the existing optical switching speed is limited. In some scenarios that require a fast response, the switching speed may still not be fast enough. For example, when suddenly encountering strong light, the window may not be able to darken to the ideal state immediately. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a system and method for controlling optical switching, which can effectively solve the problem of limited optical switching speed in the prior art.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] The present invention provides a system and method for controlling an optically switchable device, comprising a material capable of optical switching and a control system, wherein the optically switchable material is an electrochromic material with a fast response time, and the electrochromic material comprises one of vanadium oxide and titanium oxide, and different types of coatings are applied on a substrate of the electrochromic material, and the coatings comprise an anti-reflective coating, a hard coating and an optical enhancement coating, and the control system is composed of a sensor module, a controller module, an actuator module and a communication module;

[0007] The sensor module is used to detect various parameters in the environment, and the parameters include one of light intensity, color and temperature;

[0008] The controller module is responsible for processing the data collected by the sensor module and processing it according to the preset algorithm and logic, and can make decisions quickly and accurately;

[0009] The actuator module is a key part to achieve the change of window transparency, and is used to perform optical switching operations according to the instructions of the controller module;

[0010] The communication module is used to control the communication between the internal components of the system and with external devices, realize data exchange and control command transmission with external devices or networks, and thus support remote monitoring and control functions.

[0011] According to the above-mentioned system and method for controlling optical switching, the sensor module uses a light sensor with good accuracy and can accurately detect subtle changes in light intensity. As sunlight gradually increases or decreases, it can promptly sense and provide accurate data to the control module to ensure that the window transparency is adjusted accurately and appropriately.

[0012] According to the above-mentioned system and method for controlling optical switchability, the controller module uses an STM series microcontroller, which has efficient processing capabilities and low power consumption characteristics.

[0013] According to the above-mentioned system and method for controlling optical switching, the actuator module designs a suitable driving circuit according to the selected optical switching material, and the optical switching material is an electrochromic material, which can achieve continuous adjustment from transparent to dark by simply applying voltage, providing more precise light control.

[0014] According to the above-mentioned system and method for controlling optical switching, the communication module adopts a Wi-Fi module, which can provide a relatively high data transmission rate, so that the smart window system can quickly receive and send a large amount of control instructions and status information. In complex scenarios where multiple smart windows are controlled at the same time, the Wi-Fi module can respond quickly to ensure that the status of all windows is updated synchronously.

[0015] According to the above-mentioned system and method for controlling optical switching, it also includes a user module, which allows users to access and control optical switching from any device connected to the Internet by developing a responsive web interface, so that each user can set the conditions of optical switching according to their own preferences.

[0016] According to the execution steps of the above-mentioned system and method for controlling optical switchability, it is characterized by comprising the following steps:

[0017] S1. Preparation

[0018] Material selection: First, prepare an electrochromic material that can be optically switched. The electrochromic material includes one of vanadium oxide and titanium oxide, which can quickly change its optical properties after applying an electric field, thereby quickly adjusting the transparency or color of the optical device;

[0019] Prepare the surface: Before applying the coating, ensure that the electrochromic glass surface is clean, flat, and free of grease or other contaminants. Cleaners and appropriate surface treatment techniques (such as plasma treatment) are usually used to ensure surface cleanliness and good adhesion.

[0020] Coating selection: These include anti-reflective coatings, hard coatings, and optical enhancement coatings. Often, a combination of different types of coatings may be optimal, resulting in better performance in the optical switching properties of the electrochromic material.

[0021] S2. Sensor data acquisition

[0022] First, determine the conditions for optical switching (such as light intensity and color), then select a light sensor with high accuracy and fast response speed according to the switching conditions, and use the light sensor to sense the light intensity and color in the current environment;

[0023] S3, sensor data collection and preprocessing

[0024] Collect data: Set up the system to obtain data from sensors periodically or in an event-triggered manner;

[0025] Preprocess data: perform necessary filtering, smoothing or correction on sensor data to ensure data accuracy and stability;

[0026] S4. State judgment and decision algorithm design

[0027] Define states and strategies: Define different states and corresponding switching strategies based on sensor data and preset switching conditions. When the light intensity is high and the indoor temperature is too high, you may need to reduce the transparency of the window to reduce indoor heat and light.

[0028] Specify decision-making algorithm: Based on preset thresholds and rules, design a decision-making algorithm to determine whether to perform the switching operation of the optical device. When the light intensity exceeds a certain threshold and the indoor temperature is high, the transparency of the window will be reduced;

[0029] S5. Control actuator

[0030] Based on the results of the decision algorithm, a control signal is generated and sent to the actuator of the optical device. When the optical switching material is an electrochromic material, its structure or charge distribution will change when an electric field is applied, thereby changing the light transmission properties. When the external light is too strong, an appropriate forward voltage is applied to the electrochromic material to darken the glass and reduce the light entering the room. Conversely, when the light is insufficient, an appropriate forward voltage is applied to the electrochromic material to brighten the glass.

[0031] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0032] 1. The present invention selects an electrochromic material with a fast response time as an optical switching material, which can quickly change its optical properties after applying an electric field, thereby quickly adjusting the transparency or color of the optical device, optimizing the electric field design and material structure, and further improving the response speed and the accuracy of the switching effect. Applying different types of coatings on the substrate of the electrochromic material may achieve the best effect, thereby obtaining better performance in the optical switching performance of the electrochromic material;

[0033] 2. The present invention can automatically adjust the light transmittance according to the external light and temperature through the control system. When the external light is too strong, an appropriate forward voltage is applied to the electrochromic material to darken the glass and reduce the light entering the room. Conversely, when the light is insufficient, an appropriate forward voltage is applied to the electrochromic material to brighten the glass and improve the use effect.
