The Smart Home System Based On Power Line Communication Research

With the rapid development of economy, the need of people to be resided to the home lifemore and more delicate, has from pure capacious and bright, to the pursuit of individualcharacter style, the Chinese have a kind of special emotion to the family, will be for householdlife spend a lot of human resources, hope to keep up with the trend of The Times household life.So what are the main trend of the modern society? Must be intelligent. Along with thedevelopment of the embedded, more and more intelligent device is developed, into all walks oflife, to the ordinary people. Special representative is smart phones.2010years ago, most peoplewill still use the function of the machine, the mobile phone is a mobile phone, for people cancalling and texting, that’s all. After smart phones, has more than its share function machine,bring the great change, phone has become one of the most basic function of smart phones,connected to the Internet by mobile phones, can do a lot of we haven’t been able to realizefunctions. So smart home need to get to know the situation of the whole household, this requiresa variety of sensors, cameras, auxiliary relay and other electrical equipment, and one of themost important is the data exchange process. Wireless wifi easy to use, but no radiation hazard,signal affected by the housing structure, additional costs from the professional line, electricpower carrier wave technology is the most suitable for smart home communication technology.Using the power carrier technology, high-performance ARM chips, GSM/GPRScommunication module, high sensitivity of the human body infrared detector, high-definitioncameras constitute a smart home system serial port. In this paper designed a kind of smart homesystem based on electric power carrier, its intelligent degree is high, quick, low cost, save thecommunication flow.This article mainly from two aspects of hardware and software intelligent householdsystem was studied, the hardware circuit mainly includes ARM main control center,GSM/GPRS module circuit, electric power carrier communication circuit, infrared human bodydetection circuit, single chip microcomputer trigger circuit and serial camera circuit. Softwareprograms mainly for STM32F107management and control procedures, using C language towrite. MCU only responsible for the control center of human body infrared detector trigger towork.Main innovation point of this article is based on the power carrier alarm control, infrareddetector to detect the human body, through the power carrier communication to ARM totalcontrol center, control center to start the camera, camera, send a picture taken, STM32F107finally through the GSM/GPRS transmission to target mobile phone. By changing the sensorsor relay, the system can also have the fire, gas, water, lighting control anytime and anywhere.
