System and method for intelligently controlling indoor environment based on thermal imaging technology

Abstract

The invention discloses a system for intelligently controlling an indoor environment based on thermal imaging technology, which comprises a thermal imaging sensor, a human-computer interaction interface device and an area controller, wherein the thermal imaging sensor acquires thermal imaging data of the indoor environment and identifies and analyzes the thermal imaging data so as to calculate a subjective radiation temperature; and the area controller adjusts the refrigerating and heating capacities at the tail end of an indoor air conditioner according to the subjective radiation temperature and the temperature set by the human-computer interaction interface device so as to perform optimized control on the indoor environment to achieve a temperature comfortable for indoor personnel. The system and a method for intelligently controlling the indoor environment based on the thermal imaging technology can adjust the temperature of the indoor environment, improve the personnel comfort level and work efficiency, reduce the energy consumption and improve the management level of an automatic control system of a building under the condition of acquiring comprehensive environment and personnel information.

Description

technical field [0001] The invention relates to the technical field of indoor environment control, in particular to an indoor environment intelligent control system and method based on thermal imaging technology. Background technique [0002] The control of the indoor environment depends on the control of the HVAC terminal equipment. In the current market, the terminal control of HVAC equipment is mainly based on point temperature measurement of thermal resistance temperature measurement. Point temperature sensors are usually placed in the controlled environment or measure the return air temperature at the return air vent of the air conditioner. However, the measured temperatures are often not representative due to the uneven temperature distribution in air-conditioned rooms. In addition, this type of control method cannot sense whether there are people in the room, and cannot realize important functions based on thermal imaging visual temperature sensors, such as: judging...
