[0002] With the improvement of people's living quality, the requirements for the comfort of the indoor living environment are becoming increasingly stringent. As the key indicators to measure the comfort of the living environment, the regulation and control of indoor temperature and humidity have attracted more and more attention. As an important barrier for the interaction between the indoor and the external environment, the main functions of curtains are concentrated on basic levels such as light shielding and privacy protection.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Embodiment 1 An energy-saving curtain system with intelligent adaptive temperature and humidity regulation, the system includes a data acquisition module, a data processing module, an energy recovery module, an adjustment module, and a shape memory alloy drive mechanism; The data acquisition module adopts an event-triggered acquisition method. When the temperature and humidity change exceeds the set threshold, it actively and real-time acquires environmental data including indoor temperature and humidity, and light intensity, and transmits it to the data processing module through wireless communication technology. The event-triggered acquisition avoids the energy consumption waste of continuous sampling, only starts the acquisition when the environment changes significantly, improves the data validity while reducing the system power consumption, and the multi-parameter acquisition provides comprehensive environmental information for subsequent adjustment; The data processing module generates accurate adjustment instructions by analyzing and calculating the environmental data through the built-in Kalman filter algorithm and fuzzy control algorithm. The Kalman filter eliminates data noise and improves the accuracy of environmental parameters. Then, the fuzzy control algorithm realizes non-linear adjustment based on multi-parameter input, making the action of the curtain light-shielding layer more in line with the actual environmental requirements and avoiding the lag of traditional control; The shape memory alloy drive mechanism is used to drive the movement of the light-shielding layer of the curtain. With the temperature-induced deformation characteristics of the shape memory alloy, it can achieve precise mechanical actions, drive the light-shielding layer to adjust the light-shielding area, and thus control the indoor temperature and humidity; The adjustment module drives the shape memory alloy drive mechanism through pulsed current and is used to receive the adjustment instructions generated by the data processing module, accurately control the movement of the light-shielding layer of the curtain, and realize the adaptive adjustment of the indoor temperature and humidity. The pulsed current drive accurately controls the deformation amount of the shape memory alloy, realizes the fine adjustment of the angle and speed of the light-shielding layer, and ensures the timeliness and accuracy of temperature and humidity adjustment; The energy recovery module includes piezoelectric materials, energy storage capacitors, and an energy management circuit. The piezoelectric materials are arranged on the movement path of the shape memory alloy drive mechanism. When the shape memory alloy drive mechanism operates, the energy generated by driving the light-shielding layer by the shape memory alloy drive mechanism is recovered using the piezoelectric effect and stored in the energy storage capacitor. The stored energy can supply power to the acquisition module, data processing module, energy recovery module, and adjustment module, reducing the dependence on external power supplies, achieving the purpose of energy conservation, converting the mechanical energy of the drive mechanism into electrical energy using the piezoelectric effect, realizing the recycling of energy, reducing the dependence on external power supplies, and reducing energy consumption.

[0024] Furthermore, the system also includes a mode switching module, which includes a sleep mode, a leaving-home mode, and a visiting mode. Different temperature and humidity adjustment parameters are preset for different modes to meet the personalized needs of users in different scenarios through multi-mode design, realizing automatic adjustment through preset parameters, and enhancing the user experience.

[0025] Furthermore, the system also includes a remote monitoring module, which realizes remote control and status monitoring through a wireless network. Users can view the system operation status and perform control at any time and anywhere. The remote monitoring function allows users to view the operation status of the light-shielding layer of the curtain in real time, enhancing the convenience and intelligence of the system.

[0026] Furthermore, when the Kalman filter algorithm built in the data processing module processes environmental data, the following state space model is adopted: State prediction:

[0027] Covariance prediction:

[0028] Kalman gain:

[0029] State update:

[0030] Covariance update:

[0031] Among them, is the state prediction value at time is the state transition matrix, is the state prediction estimate at time is the control matrix, is the control input, is the predicted covariance at time is the process noise covariance, is the Kalman gain, is the observation matrix, is the observation noise covariance, is the observed value at time is the state estimate value at time is the estimated covariance at time, which can effectively eliminate noise interference, improve the accuracy of data, provide reliable data support for the fuzzy control algorithm. The Kalman filter estimates the system state in real time through a recursive algorithm, effectively suppressing the random noise in the environmental data, providing a more reliable data basis for fuzzy control, and improving the accuracy of the adjustment command.

[0032] Furthermore, the fuzzy control algorithm built into the data processing module takes the temperature and humidity deviation, the rate of change of temperature and humidity, and the light intensity as input parameters. After input variable fuzzification, fuzzy rule reasoning, Mamdani fuzzy reasoning, and centroid method defuzzification, it outputs the adjustment angle and movement speed of the light-shielding layer, thereby generating accurate adjustment commands. Since fuzzy control does not rely on an accurate mathematical model, it can handle the complex coupling relationship between temperature, humidity, and light, and realizes adaptive adjustment through the fuzzy rule base, making the action of the light-shielding layer of the curtain more in line with the actual environmental requirements.

[0033] Furthermore, the control width of the pulse current used by the adjustment module to drive the shape memory alloy drive mechanism is 5 - 10 ms, and the frequency is 1 - 5 Hz. By accurately setting the pulse parameters, it avoids the failure of the shape memory alloy due to excessive current and overheating, and at the same time ensures that the drive mechanism responds sensitively, realizes the smooth movement and accurate angle control of the light-shielding layer, and improves the adjustment efficiency.

[0034] Furthermore, the mode switching module includes a sleep mode, a leaving-home mode, and a visiting mode, which are selected through the control panel or the mobile phone APP. The multi-terminal operation method improves the convenience of user operation, adapts to different usage scenarios, and enhances the human-computer interaction experience of the system.

[0035] Furthermore, the data acquisition module includes at least 3 temperature and humidity sensors and 2 light intensity sensors, which are evenly arranged at different positions in the room. The multi-point distributed sensor layout eliminates the measurement blind spots of the indoor environmental parameters, ensures that the collected data can truly reflect the overall temperature, humidity, and light conditions in the room, and provides a comprehensive basis for the adjustment decision.

[0036] The embodiments disclosed in the present invention are preferred embodiments, but not limited thereto. Those of ordinary skill in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of the present invention, they are within the protection scope of the present invention.
