HC intelligent home network 1 Background 2010 World Expo in Shanghai World Expo China Pavilion is located in the heart of China's planning area. Including the China Pavilion China Pavilion China Pavilion area, Hong Kong, Macao Museum of three parts. One area of China Pavilion 20000m2; in China building area is 30000m2; Hong Kong, Macao and Taiwan Pavilion area of 3000m2, Hong Kong, Macao and Taiwan were separate halls, each hall floor area of 1000m2. The overall project goal is: to establish an advanced, complete building wiring systems for various applications, including voice, data, multimedia, etc., to provide access and the wiring, to make system configuration flexible and easy to manage, and easy to maintain easily expanded purpose. Shanghai Expo this project is highly symbolic building, following the design of this project Program And Product Expand introduced respectively. 2 System Design China Pavilion our cabling system to system design, computer networks, to fully meet the information system about the transmission of the next 10 years, the needs of development and the overall system architecture according to the China Pavilion and future trends for the entire center of intelligence system provides a high-speed information transmission, exchange of integrated physical platform. This project we integrated wiring system by three star topology design, divided into the core layer, convergence layer and access layer. CD data distribution frame buildings, and buildings placed in the State Museum the first floor patch panels BD hub, voice patch panel BD placed the building wiring engine room. FD placed on weak floor patch panel, the service range to the distance between each route point does not exceed 90m. The same time, taking into account the special needs of the China Pavilion, we will be intelligent office network system is divided into two sets of network and public networks, physically isolated. Intelligent office network which provide other weak systems (such as BAS, etc.) access and administrative office staff use of information technology resources; the public network to provide exhibitors the main use of information resources. Based cabling system design, and design, including: (1) cabling system in the China Pavilion part of the work area, the main consideration of three elements: Voice: normal voice point; Data: intelligent office network information point, public network of information points, etc.; Wireless AP: In the hall, Meeting Rooms and public areas as the deployment of the wireless AP points added wired LAN. (2) Information Point layout principles: including ordinary voice, intelligent office network of information points, public information points network requirements common. Point bit allocation: in the work area, common voice, data points are used Category 6 Unshielded RJ45 Module; information point module is installed using wall mounted model and columns installed along the way, that information points to the wall and column spaces embedded piping and 86 bottom box and package with 86 panels; a separate part of the fiber to the desktop information points; Basic configuration information point for each work area set up in accordance with a voice point, a data point, the appropriate reserve way back up the information points, all information points based on actual usage by drawing reasonable set; the same time, taking into account China Pavilion as the office has a large office area and the exhibition of large-bay area, so in each work area set up regional weak box office area to be secondary Decoration Completed the laying of cable box and from weak to export the work zone information; B, the China Pavilion exhibition hall for the area, were set up 216 information boxes, information boxes for each voice set four points, four data points; which the information box 31 also includes an optical information points. Information box installed in the trench, the information exported directly by 86 panels installed in the information box; Level work area subsystem will lead to management subsystem, mainly Category 6 UTP cable and 4 core cable; level of voice and data systems using Category 6 UTP cable with cross skeleton and 6 categories with two holes, or four-hole information outlets, high-speed data and voice signals for transmission, the transmission characteristics to meet the 250MHz, and then jump needed for voice or data point; all the cables meet the low smoke zero halogen Flame Retardant Characteristics, to ensure fire-retardant, smoke-free and non-toxic, and uses different colors to distinguish the data points or voice points; level point of a 4-core optical fiber multimode fiber; Vertical trunk system will be the main distribution frame MDF connected with the joint topology, mainly on the number and 10G with a large cable; Voice trunk 50 and 25, with 3 categories on the number of large cable; data backbone network in every public Wiring between floors using a 24-core multimode fiber laid 10G; intelligent office network wiring in every room with a floor of 24 core 10G multi-mode fiber and two 12-core single-mode optical fiber laying 10G; Devices use jumpers and fiber optic subsystems connecting unit to connect Host And network equipment; Communicate Room subsystem distribution wiring in the shaft on each floor, the management level of each layer wiring, connect the corresponding network devices, commonly referred to as wiring between floors; Complex of buildings between the various subsystems and interconnect termination.
