Existence induction device based on human face recognition and circuit control system

Abstract

The invention provides an existence induction device based on human face recognition and a circuit control system. The existence induction device comprises an image collection module and a master control module; the existence induction device is arranged at an entrance; an image collection module in the existence induction device can obtain motion image information of an object and transmits the motion image information to the master control module; the master control module generates personal in and out information according to the motion image information and calculates number of people in a space; and the master control module can also output a high level or a low level. The existence induction device based on human face recognition and the circuit control system can regulate and control indoor electric appliances according to a condition of personal in and out, enables the indoor electric appliance to exert maximum efficiency, and genuinely saves energy resource, and is easy in installation and low in cost.

Description

technical field [0001] The invention relates to the field of human body presence sensing, in particular to a face recognition-based presence sensing device and a circuit control system. Background technique [0002] The presence sensing device is a sensing device that captures the characteristics of the human body through sensors to determine whether there are people in a certain area. This type of device is generally used to control the switch of home security or the switch of common electrical appliances to reduce manual operations and save energy. purpose of emission reduction. [0003] However, in the prior art, such human presence sensing devices often adopt technologies such as infrared sensing and radar sensing. Infrared sensing has the following disadvantages: it is easily interfered by various heat sources, light sources, radio frequency radiation, and hot air; the passive infrared penetration is poor, and the infrared radiation of the human body is easily blocked;...

AI Technical Summary

Problems solved by technology

Infrared sensing has the following disadvantages: it is easily interfered by various heat sources, light sources, radio frequency radiation, and hot air; the passive infrared penetration is poor, and the infrared radiation of the human body is easily blocked; when the ambient temperature is close to the human body temperature, the detection and sensitivity are significantly reduced , sometimes causing short-term failure; this kind of infrared technology is difficult to accurately determine the number of people, if several people enter and exit at the same time, it is impossible to accurately determine the number of people, thus easily causing energy waste

But if it is in some larger spaces, it is necessary to install
