Zigbee Wireless Technology In The Indoor Control Network Applications

Along with the network economy development, the Smart Home becomes the hot topic of discussion gradually. Simultaneously along with the development of network technology, the realization of the Smart Home has laid the practical foundation. The room control network belongs to a part of the Smart Home system, which makes all kinds of home use facility (such as illumination, home electrical appliances, entrance guard control etc.) interconnect, and causes people's life to live at home to be more comfortable, to be safe and effective.This article gets rid of carrying on the design through the wired way in the traditi on, on the contrary I use the wireless communication technic to carry through the Smart Home network design.First, through the analysis and the comparison for related technology used in the Smart Home, I pointed out at present the ZigBee wireless technology is one of the suitable technical standard used in the Smart Home system. Simutaneously, I went deep into analyzing ZigBee technical standard, which was the elementary knowledge before carrying through development about ZigBee.In succession, I carried on the design of wireless modules. The hardware module core of this system used Freescale's micro controller MC9S08GT60 and radio frequency chip MC13192. On the base I established the wireless module for the Smart Home, such as switch control module, light adjustment module, temperature gathering module and infrared communication module and so on. In the hardware design process, I brought forward replacing Freescale's copper membrane antenna by the ceramic antenna, which boosted up the signal strength, and expanded the cover scope of wireless module. At the same time, I gave a detailed analysis to the module software test,such as serial port connection module test, W/R Flash module test,and SPI test between MC9S08GT60 and MC13192.Then, I described the realization of room control network . The system software platform is the codewarrior IDE, I used C and ASM in process of the software design, referred to SMAC offered by Freescale,and then established own application procedure, in the channel access conflict question, put forward using CCA to resolve it. Ultimately formed a simple room control network, and afforded the demonstration to the network, simultaneously pointed out the question and insufficiency in the development.Finally, made the summary to the research situation for this topic, simultaneously pointed out the further research direction of the topic.
