【摘要】 利用现成的低压电力线组建家庭控制网络,具有方便、经济的优势。文中从分析低压电力线的特性入手,针对用其传输家庭控制网络数据所面临的困难和不足,提出了在低压电力线网络的运行中引入一种新型的MAC层协议的方案。该方案由于增加了优先级机制、信息加密和虚拟载波监听(VCS)等技术,使网络在实际应用中,在可靠性、安全性和满足不同控制信息对时间的要求等方面,有所改善。更多还原

【Abstract】 The scheme that uses PLC to construct home control network is more convenient and economy. From the point of PLC characteristic in low-voltage network and for the existed problems in the home control network,a new MAC layer protocol is proposed in this paper. And then PRI,information encryption and VCS are add to this PLC scheme,and these effective measures improve the home control network characteristics on reliability,security and response time.更多还原
