Design of an Intelligent Window and Research on Its Key Technology

Most of the intelligent windows sold on the market are simple windows that can only be opened and closed by remote control, or windows that can be linked with curtains and exhaust fans to achieve other functions. Their functions are relatively single, which can not fully reflect the advantages of “intelligence”, and they are not real intelligent windows. Therefore, in view of this problem, a new type of intelligent window was designed. The design of the window includes the structure design and the control system design based on STM32 MCU. At the same time, the key technology of tracking the sun light and reflecting the sunlight into the room was studied. The angle relationships between the outgoing light and the rotation axis of the mirror louver, the plane of the louver, the incident light and the outgoing light were determined. According to these relationships, the angle of the louver was controlled and adjusted, so as to reflect the outdoor sunlight into the room. Finally, it can realize four functions, such as opening and closing automatically, rain proof, inducing wind and improving indoor lighting, so that it can become a real intelligent window.
