Design And Implementation Of Smart Home Based On Wireless And Infrared

Intelligent,convenient and faster are become the people's favourite theme in the rapidly development epoch of information technology.With the rapid development of the Internet,the concept of Smart Home was slowly involved.Smart Home contains the network communication technology,integrated wiring technology,automatic control technology and security technology,it is a reflection of the Internet.Smart Home well make the household more convenient and integrates household control with indoor environment monitoring.In this paper,infrared remote control has been designed due to the home appliance equipment available in the market are mostly use infrared remote control technology,you need to understand the working principle of the infrared,infrared encoding and decoding,and familiar with infrared remote control technology to realize this system.But,there are many different kinds of infrared coding protocol in the home appliance,we can't adding relay uniformly.Therefore,we use the more popular learning technology of infrared in this paper,send different infrared remote control code from the infrared control module,Ultimately,control different appliances.We need set up the infrared emission circuit,infrared receiving circuit and infrared storage circuit for realize the function of this system.In terms of home environment monitoring,people are more care about the surrounding environment lead to the indoor environmental monitoring are everywhere.The other part of the system function in this design is collection and indoor environmental indicators by CC2530 Zigbee module.This system was composition by infrared control module,gateway,Zigbee coordinator and Zigbee sensor,among them,gateway(ARM Cortex-A8)was communication by the router connection,gateway through wireless network control Zigbee coordinator and Zigbee coordinator and respectively control the infrared control module and Zigbee wireless sensor Zigbee nodes.Users will be able to integrated control home appliance such as TV,audio equipment,electric fans and lights by infrared code learning.Zigbee wireless sensor can collect indoor temperature,humidity,light intensity,the intensity of pressure and air quality,etc,and send the collect data to the gateway by CC2530 microcontroller in real time.So,the user can integrates household control with indoor environment monitoring.
