Method and system for judging existence induction of human body

Abstract

The invention relates to a method and system for judging the existence induction of a human body. The method comprises the following steps of: entering an initial detection state, detecting whether a first motion signal and / or a second motion signal exists in a space, and under the condition that the first motion signal and / or the second motion signal are / is obtained, entering first detection time and outputting a human existence signal; detecting whether a first human body motion signal or a human body breathing and heartbeat signal exists in the space at the first detection time, and under the condition that the first human body motion signal or the human body breathing and heartbeat signal is obtained, keeping outputting a human existence signal and prolonging the first detection time; and under the condition that the first human body motion signal or the human body breathing and heartbeat signal is not obtained within the first detection time, outputting a man nonexistence signal at the end of the first detection time, and returning to the initial detection state. With the method and system adopted, sensing accuracy can be improved, and misjudgment of load equipment is reduced.

Description

technical field [0001] The present invention relates to the field of smart home technology, in particular to a method and system for judging human body presence sensing. Background technique [0002] In recent years, with the progress of society, the rapid development of science and technology, and the continuous improvement of people's living standards, energy consumption has also increased day by day, and energy conservation and environmental protection have become a new hot research topic. [0003] In the field of daily electricity consumption, in order to achieve energy saving and environmental protection, various inductive load devices controlled by sensors have emerged, such as sensor lights and sensor cameras that are widely used in public areas. This type of inductive load device automatically starts up after detecting human motion, and then after a certain period of time, if no human body movement is sensed again, it will automatically shut down, so as to achieve th...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, inductive load devices usually use a single sensor for sensing, but the existing sensors have various deficiencies in the application process, such as the commonly used infrared pyroelectric sensor, which can sense the human body with a relatively large movement, but it cannot sense the subtle body movements of the human body, and it is easy to automatically shut down the device before the person leaves, affecting normal use

Another commonly used microwave radar is sensitive and can sense small movements and changes, but it is prone to misjudgment, resulting in false start-up of equipment, which cannot meet the energy-saving effect
