Abstract

The invention discloses an infrared detection and image processing-based feedback control system, and belongs to the field of intelligent control of electric appliances. The system comprises a singlechip, a camera, an infrared probe, a loudspeaker and interfaces, wherein the singlechip is respectively connected with the camera, the infrared probe and the interfaces bilaterally; the output end of the single chip is connected with the input end of the loudspeaker; a storage device can be added to the system for expanding memory; and the system is connected between a temperature controller and a switching valve of an air conditioner when in use. The infrared detection and image processing-based feedback control system is an externally added device, is used for detecting the existence of a human body and the closing situation of a window without influencing normal use of the air conditioner or redesigning the structure of the air conditioner, can make an alarm prompt sound, and has the characteristics of simple structure, low cost and good expansibility.

Description

technical field [0001] The invention relates to a feedback control system, in particular to a feedback control system based on infrared detection and image processing and applied to energy-saving control of air conditioners, which belongs to the field of electrical intelligent control. Background technique [0002] At present, the problem of shortage of power resources is becoming more and more prominent, and air conditioners are one of the high energy consumption appliances in daily life. In the actual use of the air conditioner, some people do not turn off the machine after leaving the air-conditioned room or do not close the window when the air conditioner is turned on, resulting in a waste of electric energy. [0003] Existing air conditioners can only detect the indoor temperature, and automatically start or shut down according to the set temperature value to achieve the purpose of energy saving. However, it is impossible to judge whether there are people in the room or...
