These include – Physical - Ethernet, TCP/IP – Human readable - HTML, JAVA, Active X – Machine readable - XML, SOAP, SNMP, SMTP • Web pages for user interface • IT data standards for open communications between devices These standards will dominate in the future 7 Proposed architecture Client PC’s with Web Browser oBIX (Ethernet / TCP/IP/XML / HTTP) Intranet Network based controller LonTalk Controller LonTalk Controller LonTalk Controller 8 Other Protocols Room Controller LonTalk BACnet Room Controller Other XML based system Network based controller Controller Controller Enterprise Application Servers Standards Industry specific standards are required to define: Data Modeling, units, accuracy, time standards, etc. for exchange of data. Definition of services for functions such as alarms, schedules, trends, etc. Security in terms of both data authentication and encryption Methods for network discovery and configuration. 9 These need to work for all facility management (HVAC, Lighting, Security, Energy, Electrical, Blinds, etc.) Challenges • Today many vendors are using XML and web services in their products in a nonstandard method • Standards are needed sooner rather then later • These will not replace BACnet and LonTalk • A commitment is being made by the industry to accomplish this work 10 oBIX • In April of 2003 CABA created a committee to look at using Internet standards for interoperable facility management • Presently there are 90 members involved from around the world • Committee has 5 working groups – Data Model, Services, Security, Network Management and Marketing • Goals are to move fast and create a nonbinding guideline 11 oBIX • Committees are all active - strong focus on the data model • Goal is to release the first draft in early 2004 • Interested in more information? – – – – Membership is open to all!
