An Embedded Socket Based on Microprocessor-Based Infrared Remote Control Signal Decoding Mode

Abstract

The invention relates to a microprocessor-based embedded socket adopting an infrared remote control signal decoding mode. The embedded socket comprises an external power interface, a main board and an output interface, the main board comprises a microprocessor, an infrared receiving module, a direct-current voltage stabilizing power module, a two-way relay driving module and a current detection module. The embedded socket acquires current signals of the output interface, and automatic power off is realized to protect load components when a load current is overhigh; when the load current is a standby current, power is automatically cut off to realize a function of power saving. By the infrared remote control signal decoding mode, decoding of any keys of any infrared remote controls can be realized without infrared signal match learning, and power restoration of the embedded socket is realized. In addition, functions of electric shock prevention and automatic power off can be realized, operations in power restoration are pretty convenient, and functions of master control and control acceptance can be realized.

Description

technical field [0001] The invention relates to an embedded socket, in particular to an embedded socket based on a microprocessor-based infrared remote control signal decoding method. Background technique [0002] At present, with the development of science and technology, more and more household appliances have entered the homes of ordinary people. While household appliances bring convenience to people, they also have certain safety hazards. Therefore, it is necessary to cut off the power supply in time to ensure the safety of electrical appliances. It is now all through plugging and unplugging to realize the connection or disconnection of the power supply, but it is often that the user seldom pulls out the electrical plug when the electrical appliance is turned off or in a standby state, and the electrical appliance is still using electricity. However, it is very cumbersome to plug and unplug the electrical appliance every time after using the electrical appliance, and som...

Problems solved by technology

However, there is still a problem with this anti-shock method, that is, when a child pokes the socket with two conductive metals at the same time, he will still get an electric shock, and the function of this socket is single

[0004] 2. In order to cut off the power supply of the socket when the electrical appliance is turned off or in standby, and realize the function of saving electricity, there are some automatic power-off sockets at present, which realize automatic power-off through automatic detection of electrical appliances. The problem is that when the socket needs to restore power, either Is it inconvenient to operate, or it is only suitable for some people

[0008] There is also the time to control the socket on and off by setting the time, such as patent 201420357528.X, this control method is only practical for some specific electrical equipment or occasions, for many other electrical equipment, the time of power on and power off random

[0009] 3. In many cases, the use of an electrical appliance requires the cooperation of other supporting appliances, and when the user is finished using it, he usually only turns off the main appliance and ignores other supporting appliances

There are also some sockets on the market that have made different improvements to the existing socket functions, but either have a single function or are inconvenient to operate.
