1. Preface

The concept of intelligent building into China has 20 years history, in the recent decade, intelligent building got greatly construction development, various technical and application continues to mature and improve, intelligent building has become the mainstream of the 21st century construction. As the network technology, video technology and communication technology, and constantly improve the corresponding various applications also unceasingly thorough to People's Daily work and life, etc. Office building as people daily work, communication and create value sites, intelligent construction plays an important role, become to improve work efficiency, improve work method, improve the management mode of important ways.

Today's office building, besides having the fast and accurate data and voice transmission, the basic function of video conference, the network storage applications and is rising, usability, easy maintenance, demand more and more flexible expandability. Office building integrated wiring system, as the carrier of information transmission channel and for these requirements and application, provide the physical support.

2. System design goal

This building is 12 layer monomer building something about 35 meters long, about 25 meters wide, north and south, as a typical office buildings.

This building structured cabling systems, comply with the design and installation of standards for the whole building is to provide advanced, the unification and reliable data, voice and video transmission platform, fully satisfy office automation, communication automation needs, and adapt to the next 10 years with application technology upgrades development needs.

3. The system design principle

Building the comprehensive wiring as permanent link, investment has one-off. To achieve maximum utility, system design meet the following principles:

Standardization: according to the domestic and international standards for the design of the system and network equipment selection.

Scalability: support system extension and upgrades. Through the right amount of redundancy, meet the future system expands waves; Adopt appropriate international standard equipment, convenient system upgrades and equipment access.

Ease-of-use: all connectors are using standard, convenient management and use; Systems management hardware and software modular structure, convenient maintenance and replacement.

Economy: in full consideration of and meet the recent and future needs, on the basis of appropriate equipment, reduce the cost of system.

Flexibility: system use not by physical location and equipment kinds of restrictions, computer network and system port with the requirements set arbitrary.

4. System design scheme

In view of the building office USES, and consider a certain time network, communication demand growth in expansibility and flexibility, to have good adaptability, meet possible venue move, data and voice point with the appropriate redundancy, with a final determination plan is as follows:

Structured integrated wiring system USES star-shaped network topology structure. 6 buildings primarily room (MDF), the third floor and 10 floor respectively 1 wiring workshop (IDF). 1, 2, 3, 4 floor level wiring to the third floor wiring workshop; 5, 6, 7, 8 floor level wiring to ZhuJiFang; 9, 10, 11, 12 floor level wiring to 10 floor. ZhuJiFang and wiring workshop are in get close to the building elv Wells room.

The integrated wiring system is divided into five subsystems, namely workspace subsystem, level wiring subsystem, wiring workshop management subsystem, vertical lines between subsystems, equipment subsystems. Because a single building, no complex subsystem.

The scheme all adopt the resistance of the shielding Wisconsin dean 6 integrated cabling products. This product support various high rate application: ATM622Mbps, 2.4 Gb, 10GbaseTX Ethernet. Through the tal, UL and RoHS, and other related certification.

4.1 workspace subsystem

Workspace subsystem jump line by information socket and composed. The corrosion resistance of information socket single or double hole Wisconsin dean socket, flat-screen with sliding door interface, prevent dust into, with obvious above, permanent symbol to distinguish between data and voice, prevent the confusion, facilitate system interface of management. By the wall plug sockets, installed in ways from ground 300mm position. Information module USES six kinds of Wisconsin resistance RJ45 the shielding's lineup modules from, convenient installation, card line way by TIA for standard unified. Jumpers use six kinds of Wisconsin resistance than shielding's jump line.

.2 level routing sub-systems

Level by routing sub-systems from all the wiring workshop to the corresponding user work area cable composition, copper and fibre can be used. Here's the corrosion resistance of 6 class 4 Wisconsin not shielding twisted-pair cable, transmission frequency at or above 1000BASE - 250MHz, support ATM622Mbps and higher T, transmission rate data network applications.

Level cable from the cable bridge between the wiring information points, respectively, to working area each level of no more than 90m muting distance, plus the total length of jumpers ends not more than 100m. Bridge turn all have 45 ° transition section. In cable cloth in place, the cable ends are labeled, indicating the origin and destination corresponding cable. Every cable at one end user workspace 20cm, facilitate reserved about doing module; the length Wiring between the length of the reserved about 2m one end, convenient in installation jumpers disk.

4.4 vertical mainline subsystem
Vertical lines of data transmission subsystems is artery ", is "a key part of the integrated wiring system. It consists of the Lord in ZhuJiFang control-cabinet to each wiring between between the indoor within eight core control-cabinet multimode fiber and three multi-cores cable speech backbone composed. End termination in the center of the room, the other side control-cabinet Lord termination in the distribution line between distribution line frame on, adopted eight core multimode fiber, transmission rate can amount to 1Gbps above, but for high-speed data transmission provides the high quality data transmission channel.

Vertical main cable cloth are obligate when 2m, so that both ends installed jumper disk. Fiber cloth, the maximum tension process of less than 50 N, 30mm, turning radius is greater than vertical main cable firm bundle in metal bridge rack, separated by less binding 1-m.

Between 4.5 equipment subsystems

Equipment by wiring system between subsystems buildings into line equipment, telephone, data, computer, etc. Various kinds of host equipment and security wiring equipment etc. In this scheme design, building structured cabling equipment in 6 building room between subsystems.

Equipment room sub-system adopts the 19 "industry standard cabinet, used to install distribution frames, Richard line frame and on Switch and other network equipment, equipment within the facility. Between devices, and cable quasi-geoid variety. In order to manage complex of equipment and cable, equipment according to the equipment in the connection between the nets, voice classification, installation, equipment within the division between qualify device or equipment all into use different color code, to distinguish between the various USES of wiring area, convenient line maintenance and management.
