Design And Implementation Of Control System For Intelligent Home

Smart home is a living environment of people, which is installed as a platform for residential smart home system to make family life more secure, saving energy, intelligent, convenient and comfortable. The concept of smart home originated in the 1970 s in the united states, then spread to Europe, japan and other countries and had got a very good development.Smart home in china started late, did not enter china until the 1990 s.however,it developed so rapidly that both of technology level and market share of smart home developed to a certain scale. the disadvantage was the lack of a unified industrial standard.This thesis utilizes existing technology fully,designs and realizes a smart home system which has a market prospect under the premise of the analysis of existing smart home system market demand and technical requirements. The smart home is based on the communication of 2.4G wireless network protocol simpliciTI. The android Smart mobile terminal as a smart control center provides users with relevant home management and control services directly. The network control adapter as a appliance control terminal utilizes infrared remote control technology, dimming control technology and temperature sensor technology to complete control of appliance such as television and light.the main design and realization of this thesis are :1. Designing the network communication syste m of smart home with the wireless network protocol with simpliciTI wireless network protocol.2. Realizing USB communication between tablet PC and CC2511 with JNI and designing upper application on tablet PC.3. Designing circuitry of infrared receiver and trans mitter and realizing MCU infrared codec programs and self- learning program. The MCU decodes and transmits the infrared signals sent by remote control as to achieve the purpose of controlling infrared devices directly.4. Designing SCR drive circuitry, realizing the dimming program on MCU. The MCU drives the dimming controller by dimming program so as to achieve the purpose of the light for bright regulation.5. Designing temperature measurement program with smart temperature sensor DS18B20 so as to achieve the p urpose of measuring the room temperature.
