Abstract

Temperature-controlled mattress control system and method based on sleep posture detection are provided. The control system includes an information collecting unit, an information processor and an output instruction unit. The information collecting unit is used to collect a temperature parameter of a human body during sleeping, video information, and a temperature parameter of a temperature-controlled mattress. The information processing unit receives information collected by the information collecting unit, calculates a sleep posture value K, a thermal sensation value P and a facial skin thermal value Q to obtain a final estimated thermal sensation, and determines setting temperature variation of the temperature-controlled mattress based on the temperature parameter of the temperature-controlled mattress. The output instruction unit receives the setting temperature variation and the temperature parameter of the temperature-controlled mattress, and issues an instruction to a water chiller-heater unit to enable the water chiller-heater unit to carry out fluid temperature regulation.
