Abstract: Disclosed are a method and a device for obtaining a safe interval of a human body parameter in a built environment, a terminal device, and a storage medium. The method includes: obtaining a first facial image, a benchmark human body parameter, and a human body posture analysis result of a target user in a target built environment; inputting the first facial image into an emotion analysis model to obtain an emotion analysis result; and obtaining the safe interval of the human body parameter of the target user according to the emotion analysis result, the human body posture analysis result, and the benchmark human body parameter.

Abstract: A controlling method of an indoor air environment quality cooperation and control system includes: sensing whether there is an indoor person; if not, turning off an air conditioner system and a purification system, judging the values monitored by an outdoor pollutant sensor and an indoor pollutant sensor, if the value monitored by the outdoor pollutant sensor is greater than that monitored by the indoor pollutant sensor, turning off a fresh air system, otherwise starting the fresh air system; if an indoor person is sensed, calculating an IAQI according to values transmitted by a temperature and humidity sensor and the indoor pollutant sensor; calculating a ratio R of a ?IAQI and an energy consumption increase value ?P, and selecting a regulation mode with the maximum ratio R to coordinate a quality of the indoor environment; and returning and executing the sensing step.
