Motivation of Research
 The wisdom of the family is a "wisdom" living space.
 With the scientific and technological progress and living
standards to enhance.
3
 Advanced
computer
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.
