Abstract: With the continuous development of 5G, Wi-Fi, and IoT technologies, networked air conditioners with only remote control and cloud-based scenario algorithms can no longer meet the user demand for a new generation of smart air conditioners. Sensing the home environment and the state of human activity in the space, so that the air conditioner to provide users with personalized control of the perception technology has become a current research hotspot. Driven by the integrated sensing technology, it is of great significance to synchronize the RF signal on the Wi-Fi module that meets the communication capability of the air conditioner to realize the sensing of space and human. In this study, a new module integrating Wi-Fi and radar is designed, which realizes accurate perception of the presence and distance of people in the room through signal processing, AI anti-interference algorithm and other technologies, and realizes intelligent function scenarios, such as wind avoiding blowing, no-wake interaction, proximity push, and unmanned energy-saving, through the results of the sensing. The air conditioner intelligent control technology based on the passive sensing of the integrated air conditioning through the perception of the environment, the human body and automatic decision-making, giving the air conditioner active service capabilities, significantly improving the user experience of the air conditioner.
