3. Analysis of important patents in the sub-field of family environmental control technology

The number of patent literature on home environmental control technology accounts for a small proportion of the patent literature in the whole field of smart home, and the distribution time span of important patent literature in this field is not too large (it has been going on since around 2000).As users pay more attention to environmental control, the research and development of home environmental control technology is becoming more and more important. In recent years, the number of patent applications for home environmental control technology keeps increasing.

Take US6260765B1, an earlier filing date for a patent called "A remote-controlled thermostat," filed in 2000 by AMERICAN SECURE CARE LLC.The patent document discloses a thermostat system for controlling a temperature management system, including a manual mode control for switching between energy saving and comfort states, a wireless receiver for receiving a wireless mode switch signal, and a telephone communication circuit for receiving a telephone mode switch signal.It uses temperature sensors to detect the temperature of the air to transmit overtemperature or low temperature signals, sending out warnings.The user can operate in the energy saving mode used to enhance the energy saving and the comfort mode used to enhance the comfort. The operation mode can be selected by the user.The patent was granted in July 2001 and has since been cited 173 times worldwide by companies in the United States, Japan, Germany and other countries.

With the continuous development of Internet and Internet of things technology, indoor environmental control is becoming more and more extensive and convenient. It can not only control temperature, but also control indoor temperature, humidity and air quality by controlling heating, ventilation, air conditioning, biological characteristics, door and window switch, etc., so as to provide a better living environment.For example, shenzhen TCL New Technology Co., Ltd. applies for the patent CN102495617A, the invention name is "intelligent home air conditioning system with linkage function", and the application date is 2011.The scheme through dme testing user terminal equipment that carries the signal strength information, and according to the signal strength information send electric doors and Windows device command door window is shut, can realize the user home, the air conditioning system can automatically open air conditioning equipment in advance and close the doors and Windows at the same time, and can automatically adjust the room temperature, humidity, wind speed, etc., and in the user left to close the function of the air conditioning.Proposed by samsung electronics co., LTD (WO2016036062A1), an application for a patent for invention called "a can be used to set heating, cooling, ventilation and air conditioning (HVAC) system, the application date for the 2016, by biometric access to environmental information and user information, based on biological characteristics of environmental information and the user information to determine the control information, the control information to determine statistical information in a specific range, and is based on the information of control to control the HVAC system.The system's automatic induction control eliminates the need for multiple manual controls, saving energy while maintaining comfort.
