Individual thermal comfort control system and method based on computer vision monitoring

Abstract

The invention belongs to the technical field of heating and ventilation, and discloses an individual thermal comfort control system and control method based on computer vision monitoring. The control system comprises a data acquisition system, an information processing system, an intelligent voice inquiry module, a tail end control system and a biological real-time system; the data acquisition system comprises a semi-contact measurement unit and a non-contact measurement unit; the non-contact measurement unit comprises an infrared sensor and a camera; a skeleton node identification module and an Euler video amplification module are arranged in the camera; the information processing system comprises a storage module, a human body thermal sensation estimation module and a comparison module; the human body thermal sensation estimation module is used for obtaining a predicted thermal sensation value; the comparison module is connected with the intelligent voice inquiry module; the tail end control system comprises a tail end controller, and the tail end controller is connected with external equipment; and the data acquisition system and the human body thermal sensation estimation module are connected with the biological real-time system. The problem that thermal comfort cannot be met in the prior art is solved.

Description

technical field [0001] The invention relates to the field of HVAC technology, in particular to an individual thermal comfort control system and control method based on computer vision monitoring. Background technique [0002] A comfortable office working environment is the prerequisite for efficient office work. Currently, HVAC systems widely used in office buildings consume a lot of energy, but they do not meet the thermal comfort level required by personnel. Among the currently commonly used HVAC systems, such as the split-type air-conditioning system, it is impossible to accurately measure real-time human body temperature and thermal comfort information, and it is usually only adjusted when the human body is in an uncomfortable state. Therefore, there are problems of deviation and hysteresis in the adjustment of this system, and the set point adjusted by the occupants according to their own perception cannot meet the high-efficiency human thermal comfort and is not conduc...
