[0001] The present invention relates to the technical field of EC glass color control, and in particular to an EC glass automatic color change control method and system. Background Art

[0002] EC electrochromic glass reversibly changes the optical properties of the material by applying voltage to the EC glass. This change can adjust the light transmittance of the glass, thereby achieving dynamic control of light and solar radiation heat. This technology has broad application potential in the field of green buildings, because it not only improves the level of product intelligence, but also promotes the development of energy conservation and environmental protection. EC electrochromic glass has made an important contribution to energy conservation and emission reduction in green buildings.

[0003] With the widespread application of EC glass, the EC electrochromic glass control system has become more perfect and richer, and more humane. With the rise of intelligent buildings and the popularization of the concept of sustainable development, the application prospects of EC glass in the field of construction will be broader. This kind of glass can not only automatically adjust the light transmittance according to the changes in ambient light, but also can be remotely controlled through an intelligent control system, making the light and temperature inside the building more comfortable and energy-saving. In addition, EC glass can also be integrated with other intelligent building systems to achieve more intelligent building environment management. As an innovative building material, EC electrochromic glass not only has unique advantages in technology, but also shows great potential in environmental protection and energy saving. With the continuous advancement of technology and the continuous expansion of the market, EC electrochromic glass will play a more important role in future green buildings.

[0004] At present, the EC (electrochromic) control system is relatively simple in control mode, and in most cases still requires manual intervention and control.

In addition, the existing EC glass control system requires a lot of wiring work and deployment of intermediate transmission equipment during the installation process, which not only increases the construction cost, but also brings many inconveniences to the subsequent system maintenance. The existence of these problems has limited the practical application of the EC glass control system. Summary of the invention

[0059] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0060] Embodiment 1

[0061] Reference Figure 1 As shown, the present invention relates to a method for automatically controlling color change of EC glass, comprising:

[0062] Step S1: Acquire data collected in real time by outdoor light sensors and temperature sensors;

[0063] Step S2: Transmitting the data collected by the light sensor and the temperature sensor in real time to the indoor gateway device;

[0064] Step S3: The gateway device analyzes the data collected in real time by the light sensor and / or temperature sensor, and sends the analysis results to the EC glass controller through instructions. The EC glass controller outputs a corresponding voltage color change signal according to the received instructions to change the light transmittance of the EC glass, thereby changing the color of the EC glass.

[0065] The following is a detailed introduction to this embodiment:

[0066] 1: EC glass power supply system

[0067] This embodiment uses a strip-shaped photovoltaic film (a flexible photovoltaic strip) made of lightweight, flexible materials such as organic polymers, amorphous silicon (a-Si), copper indium gallium selenide (CIGS) or perovskite, etc. Their main advantage is that they can adapt to various surface shapes, including curved surfaces and uneven window frame surfaces.

[0068] The EC glass power supply system includes a photovoltaic film, a photovoltaic controller (model EPOW-KS20D), a power supply kit (battery), and an EC glass controller (model TMS320F280049 or MM908E622) connected in sequence, wherein the EC glass controller can control the light transmittance of the EC glass and thus control its color. The photovoltaic film is fixed on the surface of the window frame of the EC glass and is used to convert solar energy into electrical energy; the photovoltaic controller is used to store the electrical energy generated by the photovoltaic film in the battery, and the battery is used to provide electrical energy for the EC glass controller.

[0069] like Figure 2 As shown, the photovoltaic film is bendable and foldable and easy to install. The photovoltaic film is attached to the window frame and other profiles, and is pasted or fixed. The photovoltaic film usually has an adhesive backing and can be directly pasted to the installation surface. It can also be fixed with screws or clamps. At the same time, the power supply kit and EC glass controller are installed in the window frame profile and connected to the photovoltaic film through wires.

[0070] The photovoltaic film is responsible for converting solar energy into electrical energy. This electrical energy is then connected and coordinated with other kits such as photovoltaic controllers and battery components. In this way, they together form an EC glass power supply system. The main function of this system is to provide the required power reserve and power support for the controller on each piece of EC glass, ensuring that the EC glass can operate normally and perform its functions.

[0071] 2: EC electrochromic glass control system (EC glass control system)

[0072] The EC glass control system consists of three parts: wireless sensors (light sensors, temperature sensors), gateway devices (preferably wireless gateways), and EC glass controllers. The light sensors and temperature sensors are connected to the gateway devices respectively, the gateway devices are connected to the EC glass controllers, and the EC glass controllers are connected to the EC glass. The gateway device (wireless gateway) generates instructions based on the data collected in real time by the light sensors and / or temperature sensors, and sends the instructions to the EC glass controller. The EC glass controller outputs corresponding voltage color change signals according to the received instructions to change the light transmittance of the EC glass, thereby changing the color of the EC glass.

[0073] 1: Wireless sensor part

[0074] The system integrates light sensors and temperature sensors. The sensors are designed and installed in an open outdoor environment, and the sensors have built-in wireless communication devices, enabling seamless data transmission.

[0075] The main function of the sensor is to monitor and collect light and temperature values ​​in the outdoor environment in real time to ensure the accuracy and timeliness of the data. Through the built-in sensing components, it can continuously detect changes in light and temperature and generate corresponding electronic signals based on these changes.

[0076] These electronic signal data can well reflect the current environmental information. The sensor will process and package these collected electronic signals, and then send them to the indoor wireless gateway device in real time through the built-in wireless communication device. The wireless gateway is usually deployed in the room, responsible for receiving and processing the data from the sensor, and can perform further processing and analysis. In this way, the sensor can effectively transmit the changes in outdoor temperature and light to the wireless gateway in real time, thereby providing data support for the EC glass control system.

[0077] The wireless gateway has built-in analysis algorithms and can be flexibly controlled according to the set algorithms.

[0078] The wireless gateway can control the color change of the EC glass according to the outdoor light intensity collected by the light sensor, or according to the outdoor temperature collected by the temperature sensor, or it can also determine the color change of the EC glass based on both light and temperature factors.

[0079] According to the transmittance characteristics of EC glass, it is divided into 4 color-changing gears. The settings are: T1 transmittance is a%, T2 transmittance is b%, T3 transmittance is c%, and T4 transmittance is d%.

[0080] (1) Processing algorithm between light intensity and EC glass color transmittance

[0081] The wireless gateway has a built-in color change algorithm. When the wireless gateway receives the signal sent by the sensor, it will perform a series of calculations and processing. These calculations and processing are based on a pre-set algorithm to determine the color change state of the EC glass. Once the color change state is determined, the gateway will send the corresponding instructions to the EC glass controller corresponding to each piece of EC glass. After receiving the instructions, these EC glass controllers will output the corresponding voltage color change signal, thereby changing the transmittance color of the EC glass.

[0082] To better understand this process, please refer to Figure 3 . Figure 3 It shows a hypothetical day and night outdoor light intensity range, from A to Dlx, where A represents the minimum light intensity and D represents the maximum light intensity. X1 represents the real-time light intensity.

[0083] For example, when the light intensity in the environment becomes X1≤Alx, the light sensor will collect this signal and transmit it to the gateway. After receiving the signal, the gateway will perform calculations and finally execute the color change state of the T1 gear. This means that the transmittance of the EC glass will be adjusted to α%.

[0084] When the light intensity in the environment changes to A≤X1≤Blx, the light sensor will also transmit the collected signal to the gateway. After calculation and processing, the gateway will execute the color change state of the T2 gear. At this time, the transmittance of the EC glass will be adjusted to β%.

[0085] If the light intensity in the environment changes to B≤X1≤Clx, the light sensor will transmit the signal to the gateway again. After calculation and processing, the gateway will execute the color change state of T3 gear. In this case, the transmittance of EC glass will be adjusted to γ%.

[0086] When the light intensity in the environment becomes C≤X1≤Dlx, the light sensor will transmit the signal to the gateway. After calculation and processing, the gateway will execute the color change state of T4 gear. At this time, the transmittance of EC glass will be adjusted to δ%, α>β>γ>δ, and lx is the light unit.

[0087] In this way, EC glass can automatically adjust its transmittance according to the real-time light intensity to achieve the best light environment effect.

[0088] In addition to the above four-speed adjustment mode (which can adapt to common scenes), in order to adapt to more complex or higher-demand environments, the gateway device controls the EC glass controller to change the EC glass transmittance according to the data collected in real time by the light sensor, and also calculates the EC glass transmittance by the first transmittance formula, which is expressed as:

[0089] GT(X)=a·e -b·X

[0090] Wherein, GT(X) represents the calculated light transmittance of the EC glass, X represents the real-time light intensity collected by the light sensor, a and b are the first constant and the second constant respectively, and in this embodiment, a=0.6b=ln(60) / 100000.

[0091] (2) Algorithm for processing temperature changes and EC glass color transmittance

[0092] like Figure 4 Shows a hypothetical day and night room temperature range, from E℃ to H℃, where E represents the lowest temperature and H represents the highest temperature. X2 represents the real-time temperature.

[0093] For example, when the temperature in the environment becomes X2≤E℃, the temperature sensor will collect this signal and transmit it to the gateway. After receiving the signal, the gateway will perform calculations and finally execute the color change state of the T1 gear. This means that the transmittance of the EC glass will be adjusted to α%.

[0094] When the ambient temperature reaches E≤X2≤F℃, the temperature sensor will also transmit the collected signal to the gateway. After calculation and processing, the gateway will execute the color change state of T2 gear. At this time, the transmittance of EC glass will be adjusted to βb%.

[0095] If the ambient temperature changes to F≤X2≤G℃, the temperature sensor will transmit the signal to the gateway again. After calculation and processing, the gateway will execute the color change state of T3 gear. In this case, the transmittance of EC glass will be adjusted to γc%.

[0096] When the temperature in the environment becomes G≤X2≤H℃, the temperature sensor will transmit the signal to the gateway. After calculation and processing, the gateway will execute the color change state of T4 gear. At this time, the transmittance of EC glass will be adjusted to δ%, α>β>γ>δ.

[0097] In this way, EC glass can automatically adjust its light transmittance according to the real-time temperature to achieve the best light environment effect.

[0098] In addition to the above four-speed adjustment mode (which can adapt to common scenarios), in order to adapt to more complex or higher-demand environments, the gateway device controls the EC glass controller to change the EC glass transmittance according to the data collected in real time by the temperature sensor, and calculates the EC glass transmittance through the second transmittance formula, which is expressed as:

[0099]

[0100] Wherein, GT(X) represents the calculated transmittance of EC glass, X represents the real-time temperature value collected by the temperature sensor, c and d are the third constant and the fourth constant respectively, and in this embodiment, c=-2.36, d=95.4.

[0101] (3) Algorithmic processing between the linkage changes of temperature and light and the color transmittance of EC

[0102] In the EC glass automatic control system, the discoloration position of the EC glass can also be determined based on the combined influence of outdoor light and temperature. According to the pre-set discoloration conditions, when a certain condition is met, the discoloration of a certain position is executed. The specific position setting relationship is shown in Table 1.
