Power-off automatic-starting-preventing infrared induction intelligent switch controlled by single-chip microcomputer

Abstract

The invention discloses a power-off automatic-starting-preventing infrared induction intelligent switch controlled by a single-chip microcomputer. The switch comprises a power supply module, a touch switch module, an infrared induction switch module, a single-chip microcomputer central processing module and a relay control module. The main connection is that the power supply module supplies power to all the modules; the infrared induction module, the touch switch module and the relay control module are connected with the I / O port of the single-chip microcomputer so as to realize control of a load circuit; and the power supply module includes a voltage stabilizing module and a power-off automatic-starting-preventing module, and the power-off automatic-starting-preventing module is composed of a charge and discharge circuit and a rechargeable battery and supplies stable power to the infrared induction switch module when power is off. The switch can realize connection and disconnection through touching and automatic starting through human body induction under the condition of weak light, the switch is turned off in a delayed way under the state of no movement of people, and the switch can also prevent waste of electric energy due to the fact that the switch is in the connected state when power is on after power outage. The intelligent switch can be applied to a lighting circuit and is also practical for a part of household electrical appliances.

Description

technical field [0001] The invention belongs to a smart home control energy-saving system, and in particular relates to a power failure prevention self-starting infrared induction intelligent 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 on when the next call comes in, which will cause a certain amount of energy loss and waste. In an inc...

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 remain 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
