1 Proposal.: Communication protocol and Device description for Home Automation Control Submitted By: China March 2006 Proposal: JTC1 SC25 WG1 HES communication protocol and Universal Device Description Submission Title: Home automation control communication protocol and device description Date Submitted: [March 2006] Source: China Home network standard committee Web: http://www.chinahomenetwork.org Voice:[(86) 10-62571968], FAX: [(86) 10-62571968], E-Mail:[wangg@haier-broadtech.com] Abstract:This contribution is a complete protocol stack for home automation control. It is intended to provide a physical layer 、 Network Layer 、 Application layer protocol between different home appliances for sharing the status 、 controlling the operation. It is based on proven technology, which can be implemented at low cost and can provide scaleable home network with robust performance and low power consumption for low data rate devices intended to communicate within the home. This contribution also provides a complete home device description file format to support universal description for the controlling language between NAU and Home appliances and user interface for controlling the Home appliances. Purpose:Support Plug and Play for home appliances management Notice:This document has been approved by MII of China as the China home network industry standard and published on June,2005. SC25/WG1 N1207
