Automatic intelligent-induction electricity-saving switch and induction method thereof

Abstract

The invention relates to an automatic intelligent-induction electricity-saving switch which comprises a main controller, wherein an input end of the main controller is connected to a far-infrared detection and treatment circuit, and an output end of the main controller is respectively connected to a power switch control and drive circuit and an active detection motor control and drive circuit; and the main controller drives the action of a power switch and an active detection motor according to electrical signals output by the far-infrared detection and treatment circuit. The invention also discloses an induction method of the automatic intelligent-induction electricity-saving switch. The invention adopts the method combing passive detection and active detection, and gives consideration to the static detection of human bodies. When workers leave workplace, the whole office supply can be automatically switched off in set time. The automatic intelligent-induction electricity-saving switch solves the problems of the standby consumption and the power consumption of electrical equipment, thereby achieving the goal of saving energy. Meanwhile, when workers enter workplace, the whole office supply can be automatically switched on, and the trouble of manual operation of workers is avoided.

Description

technical field [0001] The invention relates to an automatic intelligent induction power-saving switch and an induction method thereof. Background technique [0002] At present, most smart sensor switches use pyroelectric sensors (also known as far-infrared probes, PIR) to collect human body information, and use it as a control source to control the on and off of the power supply, so as to achieve the purpose of energy saving. As far as its detection method is concerned, there are two methods: [0003] One is passive detection (the detection sensor is still): when the human body is in motion, the far-infrared radiation changes sharply, and the sensor has a signal output. When the human body is still, there is no signal output. Obviously, this method is only suitable for detection when the human body is active. , unable to adapt to the detection when the human body is still; [0004] The second is active detection (the detection sensor is always in motion): by adding a moto...

Problems solved by technology

In this way, even when the human body is still, there is still relative motion between the human body and the sensor due to the movement of the detection head, which can solve the problem of infrared detection when the human body is still, but because the motor is always in a rotating state, the loss of electric energy and equipment is increased.
