Description

Technical Field

[0001] This invention relates to the field of thermostat adjustment, and more specifically to a method and system for intelligent thermostat adjustment based on multi-source environmental sensing. Background Technology

[0002] Existing temperature control systems typically rely on a single environmental data point, primarily using temperature as the sole basis for control. This "single-data perception" approach has several limitations. First, while temperature is an important indicator of environmental comfort, it is not the only factor. Environmental factors such as humidity, air quality, light intensity, and airflow also significantly impact human comfort perception. Traditional temperature control systems often overlook the role of these factors, adjusting heating or cooling equipment based on a set temperature value, resulting in imprecise environmental regulation. Because other environmental variables besides temperature are ignored, the system's response is usually lagging and unable to adapt to actual needs promptly. In high-humidity environments, although temperature... While humidity may be suitable, people may still feel uncomfortable. Traditional systems struggle to respond effectively to humidity changes, ultimately impacting overall comfort. Furthermore, due to overly simplistic control, systems rely excessively on temperature data, leading to energy waste. Temperature control devices may continue operating even when humidity is high but the set temperature is met, resulting in unnecessary energy consumption. This "single-data-sensing" control method not only reduces indoor comfort but also increases energy consumption, affecting the system's overall efficiency and sustainability. Therefore, existing temperature control systems need to comprehensively sense and adjust multiple environmental factors to improve system adaptability, accuracy, and energy efficiency.
