Description

Technical Field

[0001] The present invention relates to the field of intelligent control technology, and in particular to an intelligent light curtain linkage control system and method based on environment perception. Background Art

[0002] In the early days of the intelligent era, the concept of smart home began to emerge, and some home automation systems began to appear, including the preliminary control function of curtains and lights. However, the system at this time was relatively simple, mainly through electronic control equipment and automation systems to achieve basic automatic control, such as timed switching of curtains and lights; with the popularization of the Internet and the emergence of Internet of Things technology, smart curtains and lighting control systems have gained new development opportunities. During this period, some smart curtains and lighting products began to have network connection functions and could be remotely controlled through the Internet; in recent years, with the continuous application of technologies such as artificial intelligence, machine learning, and big data, smart curtains and lighting control systems have become more intelligent and personalized. The system can automatically adjust the opening and closing of curtains and the parameters of lights according to changes in the environment and the habits of users, achieving a more comfortable and energy-saving effect. However, as the control of curtains and lights becomes more intelligent, although the control of curtains and lights is faster, there are still deficiencies in humanized convenience. Nowadays, automatic control can only be completed according to light and temperature, lacking analysis of user habits and experience, and how to create the living atmosphere and environment that users want through the control of lights and curtains plays an important role in improving the user experience. Summary of the invention
