Outline2Motivation of Research3The wisdom of the family is a "wisdom" living space.

With the scientific and technological progress and living standards to enhance.

Abstract4Advanced computer technology, internet communication technology.

Security defense, lightcurtaingas valve control,information household electric appliance and scene linkage were combined in intelligence home system.

Introduction5With improvement of living standards, the better home environment is required by more people. Intelligence of home design has become the world's trends.

In China, intelligent home system study is relatively late but rapid development.

Design Program of Ccntrol System(1/2) 6

Microprocessor used PIC16F946 of the U.S. Microchip Technology Inc. 64-Pin Flash-Based, 8-Bit CMOS Microcontrollers with LCD Driver , programming easy and flexible.

Brownout Reset(BOR), enhanced watchdog timer(WDT), Programmable Low-voltage detection (PLVD); built-in highly stable 8 MHz oscillator, two 8-bit and a 16-bit timersDesign Program of Ccntrol System(2/2)7Intelligent home control system can not only control a variety of household devices, but also view their status.

Can complete lighting control, intercom, security alarm, temperature and humidity control, remote control, wireless remote control, automatic curtain, scene control, sensor control etc.

Security Alarm Subsystem8

Front-end detectors include doorwindow magnetic detectors, infraredgassmoke detector and emergency alarm buttons etc.

when the external lines have been destroyed, automatically transferred to GSM network.

If there is gas leakage at the buzzer alarm ,automatic open exhaust fans Temperature and Humidity Control Subsystem9Temperature and humidity control subsystem used HIH3610 humidity sensor developed by Honeywell.

only demand one A/D converter that converts voltage value with humidity values proportional into digital interface and connects with the MCU.

Video Intercom Subsystem10Video intercom subsystem can realize the following functions: Outside visitors the host call room extension, also shows images of visitors.

After confirming guests, the master can "unlock" key to open cell door lock.

Lighting Appliance Control Subsystem11For centralized control of electrical appliances "fully open" and "all off" button was set up.

Lighting control is not only the practical function of lighting, a decorative effect and atmosphere. more attention to changes in light shade and color transformation, single or groups of lights on / off control and dimming control.

Appliance control function is not only our commonly household appliances, but also includes garden automatic irrigation systems, fountains and other equipment.

11Curtain Control Subsystem12Curtain control subsystem control all electric curtains including blinds, sunshades and skylights.

It can automatically open and close in a particular time or at the intensity of light. You can control it by panel, remote control, and even the Internet and smart phones.

Conclusion13Household appliances also dont need to transmit large amounts of data, and its real-time requirement is not high, so take a combination of wired and wireless ways to make wiring easy.

Alarm subsystem with landline phone alarm and GSM alarm has multiple protections. It can still alarm normally when the line of the landline phone is cut off.
