Sleep thermal comfort degree perception method and system and air conditioner control method

Abstract

The invention discloses a human body cold and hot comfort degree perception method and system and an air conditioner control method. The system comprises information acquisition equipment, a human body posture judgment module, a quilt covering condition determination module and a human body cold and hot comfort degree determination module, wherein video information during sleeping of a human body is acquired, the human body posture is judged according to the video information, the human body cold and hot comfort degree is determined through the human body cold and hot comfort degree determination model according to the determined quilt covering condition, the human body posture and the quilt covering condition, the determined human body cold and hot comfort degree is sent to a controller, and the controller controls an air conditioner according to the human body cold and hot comfort degree. The current thermal comfort state of the human body can be determined in a non-contact mode, then an instruction is output to control equipment such as an indoor air conditioner, and therefore the purposes of adjustment according to needs, energy saving and comfort are achieved.

Description

technical field [0001] The invention belongs to the cross research field of computer vision and building thermal environment, and relates to image signal processing, human body posture estimation, human body thermal comfort and other technologies, and specifically relates to a thermal comfort perception method, system and application for night sleep. Background technique [0002] In recent years, experts and scholars at home and abroad have done a lot of research on the thermal comfort of office environments. In addition to research on comfort in artificial environments such as traditional mixed ventilation and displacement ventilation, comfort in personalized air supply environments has also been fully studied. Duan Mulin et al. compared the effects of different air supply speeds on personnel comfort when the air supply distance and temperature were fixed; Zheng Zhimin used numerical simulation methods to evaluate the performance of the office's personalized air supply air ...
