LONWORKS Control Technology 　　In International Horticultural Exposition 2006 Shenyang, China 　　International Horticultural Exposition 2006, located in QIPANSHAN International Scenery and Tourism Development Zone, Shenyang, China, is officially open from May.1 2006 to Oct.31 2006.

　　　　　　　During opening period, there will be more than 10 millions visitors worldwide, whose senses will experience various luscious greens, magnificent display of colors and exquisite smells. There are full of 100 gardens, including 23 international, 53 domestic and 24 special designed gardens. 　

　　　　　　　International Horticultural Exposition 2006 Shenyang still includes four topics buildings, which are Wings of Phoenix- the 72 meter magnificent lofty leaning tower, Lily Tower- the 125 meter high Lily in full bloom, Rose Garden- the largest greenhouse with over 3500 varieties of roses worldwide and Comprehensive Hall-the indoor Exposition Hall with Massive 12000 Square Meter. 　　　　　　The HVAC and Streetlight control in International Horticultural Exposition 2006 is designed to use LONWORKS control technology. TAC Vista IV building management system, the world leading LONWORKS based open system, is installed and provides very flexible and reliable HVAC and Streetlight open solution. LOYTEC high performance network analysis and infrastructure is also used in International Horticultural Exposition 2006 Shenyang. 　　　In Rose Garden, the LONWORKS building automation network consists of heating, ventilation, air conditioning and so on. LONWORKS DDC FT-10 network is connected to Fiber backbone using LONWORKS Fiber data communication device. 　　

　　　　The total streetlight in International Horticultural Exposition 2006 is divided into several zones. Each zone control consists of LONWORKS DDC FT-10 controllers and LONWORKS Fiber communication device. Each LONWORKS Fiber data communication device is connected to multi-port LON Fiber data communication device via Fiber backbone. 　　　　The building management center uses high performance network interface to connect multi-port LONWORKS Fiber data communication device. LNS Network Operating System and TAC Vista Server acts as communication center and collect and control about all the HVAC and streetlight over Fiber channels. TAC Vista Servers directly access LONWORKS network via locate and remote LNS Server. LNS full client makes two TAC Vista Servers to monitor and control at the same time. The LNS full client redundant solution keeps at least one of Vista Servers running while another Vista Server crashed. In order to better manage building control networks, the network analysis and infrastructure uses LONWORKS protocol analyzer and router. The HVAC and Streetlight are locally controlled by LONWORKS based TAC Xenta 300/400 DDC controllers. SQL Server is used to record trend and event logs...
