Motivation of Research
The wisdom of the family is a "wisdom" living space.
With the scientific and technological progress and living
standards to enhance.

Abstract
technology,
internet
communication
technology.
Security
defense, light 、 curtain 、 gas valve control,
information household electric appliance and scene linkage were
combined in intelligence home system.
4
Introduction
With 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.
5
Design Program of Ccntrol System(1/2)
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 timers
6
Design Program of Ccntrol System(2/2)
Intelligent 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.
7
Security Alarm Subsystem
Front-end detectors include door、window magnetic detectors,
infrared、gas、smoke 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
8
Subsystem
Temperature 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.
9
Video Intercom Subsystem
Video 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.
10
Subsystem
For 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.
11
Curtain Control Subsystem
Curtain 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.
12
Conclusion
Household appliances also don’t need to transmit large amounts
of data, and it’s 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.
