A kind of infrared induction intelligent switch controlled by single chip microcomputer

Abstract

The invention discloses a power failure prevention self-starting infrared induction intelligent switch controlled by a single-chip microcomputer. Including power supply module, touch switch module, infrared sensor switch module, single-chip central processing module, relay control module. Main connections: the power supply module supplies power to each module; the infrared sensor switch module, touch switch module and relay control module are connected to the I / O port of the single chip microcomputer to realize the control of the load circuit; the power supply module contains a voltage regulator module and a power failure prevention Self-starting module, power failure anti-self-starting module is composed of charging and discharging circuit and rechargeable battery, which provides stable power for the infrared sensor switch module during power failure. The smart switch can be turned off by touch and automatically turned on by human body induction under low light conditions, and it can be turned off with a delay when no one is active. The smart switch can not only be used in lighting circuits, but also practical for some household appliances.

Description

technical field [0001] The invention belongs to a smart home control energy-saving system, in particular to a power failure prevention self-starting infrared induction smart switch controlled by a single-chip microcomputer. Background technique [0002] In people's daily life, switches can be seen everywhere. Basically, every electrical appliance that uses electricity needs at least one switch to control, so that people can control the use status of the electrical appliances by themselves. However, among so many switches, most of the switches are traditional mechanical switches, which need to be pressed directly by human hands to achieve effective on-off. People often forget to turn off the switch, causing a lot of waste, and these mechanical switches have no memory function. If you forget to turn off the switch after a power outage, it will continue to be turned on when the next call comes in, which will cause a certain amount of energy loss and waste. In an increasingly i...

However, among so many switches, most of the switches are traditional mechanical switches, which need to be pressed directly by human hands to achieve effective on-off. People often forget to turn off the switch, causing a lot of waste, and these mechanical switches have no memory function. If you forget to turn off the switch after a power outage, it will continue to be turned on when the next call comes in, which will cause a certain amount of energy loss and waste.

In an increasingly intelligent modern society, such switches cannot meet people's needs, and people need more automatic energy-saving switches with induction
