Power-grid-based power strip control system and method

Abstract

The invention discloses a power-grid-based power strip control system and a power-grid-based power strip control method. The system comprises a mobile terminal, a global system for mobile communication (GSM) wireless communication module, a master control unit, slave control units and power strip state detection control circuits, wherein the mobile terminal is used for transmitting operation instructions to the master control unit in a short message form; the GSM wireless communication module is used for receiving the operation instructions transmitted by the mobile terminal in the short message form, and transmitting the operation instructions to the master control unit; the master control unit is used for determining slave control units to be controlled by the instructions according to the operation instructions in the short message form, and transmitting the operation instructions to the slave control units through power lines; the slave control units are used for receiving the instructions transmitted through the power lines, and driving the power strip state detection control circuits to control power strip switches to be turned on or turned off; and the power strip state detection control circuits are used for detecting and controlling the turning-on or turning-off states of the power strip switches. Power carrier communication modules are used as the master control unit and the slave control units, and communicate through the power lines to form a local area network to realize intelligent control over power strips used by each electrical appliance in a family space.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a control system and method for plug-in strips based on a power network. Background technique [0002] With the development of information technology, smart homes have entered people's lives, and smart power strips have also entered people's lives. With telephone remote control smart power strips, you can enjoy a comfortable life with confidence! When you go out, you don’t have to worry about forgetting to turn off the electrical power, don’t worry about whether the fish tank at home is powered off, whether the automatic watering machine’s power supply is normal, and when the whole family travels, you don’t have to worry about being patronized by thieves when the lights are not on for a long time at home.

[0002] With the development of information technology, smart homes have entered people's lives, and smart power strips have also entered people's lives. With telephone remote control smart power strips, you can enjoy a comfortable life with confidence! When you go out, you don’t have to worry about forgetting to turn off the electrical power, don’t worry about whether the fish tank at home is powered off, whether the automatic watering machine’s power supply is normal, and when the whole family travels, you don’t have to worry about being patronized by thieves when the lights are not on for a long time at home. Turn on the electric blanket before going home------The smart plug strips on the market now include: intelligent timing safety plug strips, wireless remote control switch strips, telephone remote control intelligent plug strips, etc., but among their multiple plug strips There is no communication between them, and each needs a separate telephone line, which is costly. However, using power carrier communication to use power lines to build a local area network does not require rewiring, and there is no electromagnetic radiation from wireless communication. The control realizes low-cost, radiation-free remote control of multiple smart strips
