A, ensemble Taiwan wiring profile

Integrated wiring system is a set of used for buildings or buildings for computer and communication between facilities and monitoring system preset information transmission channel. It will voice, data, video equipment, and can make connected each other of the equipment and external communications data network connections. Its core is "integrated", namely all elv systems can all be integrated wiring system information transmission.

Traditional hard-wired deficiencies mainly displays in: different application system (phone, computer system, LAN, building automation systems, such as the wiring independently, different equipment adopts different transmission cable constitute their network, meanwhile, connecting cable's socket, module and the structure and production standard control-cabinet, reach different between common purpose, add construction period, which the different form is a great difference, wiring system to swap general.

Traditional wiring way with no unified design, construction, use and management is not easy. When the workplace needs to be planning, equipment need to replace, mobile or increase, only to laying cable, reinstall the plug, socket, and need to interrupt office, wiring job was slow and cost, and efficiency is very low. Therefore, the traditional wiring against wiring system comprehensive utilization and management, limiting the application system changes and the expansion of the network size and upgrades.

Integrated wiring system is to adapt to the phone and network data transmission cable management needs and developed a kind of specially designed wiring way, it is for intelligent building and intelligent buildings provides the information facilities more manufacturers compatible, modular expansion and update the possibility of flexible reorganization, system. Both for users to create the modern information system environment, strengthening the control and management, and for the user cost saving, protect the investment. Integrated wiring system has become an important part of modern architecture. The traditional wiring is bus topology, and integrated wiring is star topology, in a room with plenty of port each position selection, and each room have obligate cable, expanding the space is large, facilitates concentration control and unified management.

Integrated wiring system application high quality standard material, by the shielding twisted-pair cable and optical fiber as a transmission medium, combined pressure after way, unity of planning and design, a set of complete and open wiring system. This system will voice, data, video signal wiring and building security alarm, monitoring management signal wiring in a comprehensive standard wiring system inside. On the wall or floor Settings are standard outlets through various adapter, these sockets with computers, communications equipment and building automation equipment connections.

Integrated wiring hardware including the transmission medium (not shielded twisted-pair cable, multi-cores cable and optical fiber cable), distribution frames, standard information socket, adapter, photoelectric switches, system protection equipment.

Integrated wiring system's advantages:

(1) clear, easy to maintain.

(2) take standardized unified design, unified materials, unified wiring, unified installation construction, accomplish structure is clear, facilitate the centralized management and maintenance.

(3) materials, adapt to future unified advanced the development needs. Integrated wiring system adopts the advanced materials, such as six types of the shielding twisted-pair cable, transmission rate in l000Mb/s above, can fully satisfy the development needs.

(4) flexibility, meet different needs, use rise very flexible. A standard socket, already can pick up person telephone, and used to connect calculator terminals, realize voice/data point swap, can meet different topology structure of the LAN.

(5) facilitate expansion, already save cost and improve the reliability of system. Integrated wiring system using redundancy wiring and star structure of wiring way, unified arrangement, unified system into construction, can reduce with families and construction costs, both saved the cost, and also to improve the equipment and the system reliability, also facilitate room future development and expansion.

Second, the characteristics of computer integrated wiring

(1) the large number of information points per unit area.

(2) extensible.

(3) data transmission give priority to.

(4) fiber information points quantity.

(5) to the horizontal subsystem model mainly.

(6) route laying special, can adapt the application characteristics and computer equipment characteristics.

(7) can comprehensive planning some unconventional wiring between devices

Three, the engine room integrated wiring and building wiring the handover interface

Most center machine room between the network as big building Lord wiring between the computer integrated wiring, involved and building internal backbone handover and with telecommunication operators outside handover two parts. Building interface will room wiring as an independent level subsystems.

Four, the engine room integrated wiring system structure design

The very first step is to confirm the layout and quantity workspace information points. The ideal of course is able to determine equipment needs. So can on the current equipment is accurate information points configuration. On this basis, we'll consider certain expand 3%, generally recommend that take 10% a 20%, shoulds not be too much. For room service in the whole network, its internal equipment changes frequently, accurate, suggest more difficult is expected to consider expansion easier rather than one pace reachs the designated position. And it also can reduce costs. Consider Consider expansibility, should consider the routing channels will wiring fully.

The telecom room server and terminal numerous, equipment installation forms are divided into two main layout mode: tower server and rack-mountable equipment. Both the demand of information socket density large difference. When decorating shall determine installation mode, quantity, interface number, interface specifications.

(a) tower server

Adopt the mode, installation installed a very low density, less than 2 sets per square foot. Also have users will tower server installed in standard server cabinet, a cabinet can only be installed 2 ~ 4 sets. Still can use multilayer open wide type rack, rack for 3 layers, one frame can be installed around 12 sets per square metre server, 5 ~ 6 sets.

(2) the standard machine cabinet server

At present the most thin thickness of the server, but usually only lU cabinet incomplete filled the space. Such a standard server rack can be installed a few units (thick) to SanShiTai (thin) or so of the server, need the number of information points bigger also. Suggest a standard server rack according to 12 ~ 24 computer configuration.

In determining the amount of information points after the need for roughly, to carry on the reasonable planning cabling infrastructure. When the room area is lesser (200m2 below) in 200 points below information points by level, advice only control-cabinet model, the wiring are installed on the network, the wiring rack room all room on the received information points control-cabinet directly.

When the room with larger area, especially information points mode, will increase trough quantity and trough cross section. If trough in activities under floor layout to have precise air conditioning area caused great supply air resistance, practice shows that this is the main reason for the cooling effects influence. Meanwhile, many cable all together to one place to clear the star layout, increased difficulty cable management difficulties. Then suggest adopt two-stage wiring: level subsystems and mainline subsystem. Will FD placed in room dense information points places (such as host room), after switches, again through backbone connects to network room. This will further demand center control-cabinet structure, reduce greatly reduced cable number under each major pipeline engine room floor, reduce the probability of a fight under the influence of air distribution air conditioning.

This style of faults is increased the cost of switching equipment; Management network and system caused by two departments crossover; Many first-degree handover, reliability reduced.

Some users think through two-stage wiring will increase after network, so the method unreliability long jump line will exchange equipment and server directly connected. This way, because there was no to good control-cabinet, not recommended management.

Next, determine wiring level. System selection should choose according to need proper wiring level. At present the main use is super five categories and six types of systems. Super five kinds of system tests, and six 155MHz bandwidth to the test to such systems, can be in bandwidth 200MHz copper link support gigabit transmission. Higher performance and super six types of products. But since no related standards, are determined to measure by each manufacturer, test and appellation is not recommended.

Wiring and points shielding system and the shielding system, the difference between the two main reflected in cable. Twisted-pair cable itself is stranded by the two root of composed, again by many cable to wire and cable. It applied the concepts of balance cable: a cable have two the same conductor, two online running voltage on the reverse polarity, equal to, through mutual twisted together in a certain distance, can maintain the balance. The distance between the two wires to minimize method is will they twisted together, this helps the compensation they receive the external interference. Balance of twisted-pair cable means the two wires is the same length and size. The agreement between them and the closer together, the easier it will be to resist the external lines of interference to them. Higher transmission rate need higher lines, so the method anti-interference ability to improve system shielding wiring system bandwidth was beneficial. Usually shielding twisted-pair cable adoption each pair of lines, and then to separate shielding the line on the overall shielding all ways to implement the highest anti-interference ability. Shield cable (FTP) shielding principle is different from the balance of the principle of double twisted, FTP cable is offset in the outside of the twisted-pair add a layer or two layers of aluminum foil, using metal to the electromagnetic wave absorption and hasten the reflex, skin effect principle (the so-called skin effect is refers to the current trend in the distribution of conductor section with frequency increases and tend to conductor surface distribution, the higher the frequency, the smaller the skin depth, namely the electromagnetic wave penetration ability weaker), effectively prevent external electromagnetic thousand interference and also stop entering cable internal signal radiation out with other devices. Experiments show that the frequency of electromagnetic 5MHz only through more than 38m thick aluminum foil. If shielding layer thickness more than 38m, smoke entering cable shield can pass through the frequency of internal electromagnetic interference, and 5MHz below limitation in the low frequency interference for 5MHz following the principle of usable double skein of effective offset.

Shielding system of construction technology is difficult to stricter requirements, otherwise may actually striking unnecessary interference, decrease performance. Shielding system another main characteristic is a confidential function, can prevent information leakage. The current super five categories and six types of systems are shielding and the shielding products. Note that the selection of shielding products realize the will take, not only by shielding wire and cable has not adopted control-cabinet and socket abilities. Shield

Five, the engine room integrated wiring routing design

As stated above, the engine room wiring information points in room number and operation process, with the increase of computer and network equipment, will increase demand at any time information points. Therefore, routing design should fully consider extensibility. In the routing selection, should first try to adopt metal materials, unfavorable use PVC pipes. Through the metal pipe good grounding can reduce interference, and improve the engine room fire level. Line At the same time, using metal trough as routing materials, can make full use of trough expansibility good, easy to increase the cable characteristics. For trough layout, general arrangement around equipment. At present more and more common use cabinet, can consider and rows of cabinet parallel layout. General every row decorate a trough cabinet, can also be two rows between adjacent hallway cabinet before public a trough, a model is more ideal some. For activities of the room, usually floor practices are will trough in activities under floor installation. But as the high-end room air supply under floor in the widespread use of the precision air conditioning, the pattern exposes some problems. Because of equipment in the telecom room decorate, so every row rows of equipment are under floor configuration trough, the general trough height in 50 ~ l00mm, while laying height only foor 300mm or so, thus affecting the air duct flow. Trough, the worse the effect of air supply under the floor also tend to have (strong wire slot). And line especially in activities under floor &high lines decorate added a fire hazard, electrical breakdown may trigger fire, while under floor customs will not be quickly found that even the conventional fire feeling configuration, due to temperature feeling smoke detectors, reflecting the air supply under the floorboards not quickly. Has more than a fire accident happened from activities under floor. So, now many room especially, widespread use of the telecommunications industry walk on the routing modes. Line

Walk on line by the need to have equipment layout to cooperate, this kind of layout is mainly used in the standard rack-mountable layout occasions, and the cabinet is basically the same height should size especially, can ensure that beautiful.

Using trough walk on line. Trough have two kinds of installation mode: bracket at the top, lifting support on the ground. Support on the ground easy occurrence stents and the cabinet fight, needing attention in design.

Walk on irrelevant to slot form has two kinds: open ladder model bridge posture and enclosed. Open ladder frame is the mainstream of the application. In the design, first is still in the cabinet room plane according to the overall planning, each row all cabinet Settings. The advantages of open ladder frame is easy for maintenance. Because do not need additional opening, increase or decrease the line is convenient; Don't need to lift floor, only need a ladder can implement, small amount. Facilitate found fault. Unlike under floor closed trough, the very easily observed fault point, especially the fire danger. Its defect is to prevent rat requirements are higher.

Open ladder frame usually &high consideration together. Usually consider the three layers, which specialized in line, respectively, as copper lines and optic fiber cable channel. Because of the large computer cable especially in light of the jump line is more fragile, so the optic fiber cable bridge often USES closed-end, such layout easily management. The distance between each layer of not less than 300mm. If the room is not enough, can also reduce layer by layer, left layout. According to the regulation must pay attention to the specialized and weak elevator bays distance. If the distance still cannot reach, can consider using shielded wire or adopt &high closed.

Six, the engine room integrated wiring information points of installation modes

According to equipment installation modes and decoration methods, information socket several installation. If the telecom room decorate have raised foor, often with antistatic following equipment layout mode.

(1) tower equipment installed. Adopt activities under floor installation information socket. At the height of installation general will plug in a socket on the surface of the control of the activities under the surface of floor of distance l0cm or so, also can use in floor surface installed pop-up socket mode. But adopting pop-up socket need to pay attention to: don't will socket decorate in the walkway between devices, otherwise easily knocked off; Pop-up socket connection in the socket terminal box is activities, socket pop-up and press down easy to cause the loose; Another proposal is not more than two sockets information points, or supply socket is installed inside the box space crowded, more likely to lead to wiring loose, socket bombs do not up wait for a problem. Install boxes size and depth soprano some. Because floor socket main advantage is that facilitate open shut, so suitable for some temporary use, such as debugging check etc. But the telecom room equipment most requirements 24h uninterrupted operation, cannot use floor socket advantages.

(2) work station terminal. The foregoing information socket installation and same. Now use floor socket is more convenient.

(3) machine cabinet server. There shall be installed in the information points socket under floor pattern will no longer fit anymore, because a information socket panel usually can only be installed 2 ~ 4 socket module, this to have dozens of information points for the cabinet, and their sockets number that is too many. And from the socket to the server lines shall be introduced from activities under floor cabinet, need from cabinets below opening striking, and after fixation in installation cabinet next to the activities of the cabinet for future opens, the floor of the maintenance problems. So, on the server rack information points installation, recommended RJ45 control-cabinet model machine cabinet. A: 2U control-cabinet (including the Richard line device) can provide information points of 16 ~ 32 mouth, which can meet the capacity of most cabinet needs. And because the installed directly to the cabinet, facilitate management, installation effect tidy and beautiful. Considering the socket interface in server usually can be installed in the cabinet, control-cabinet behind.

(4) can also will more information socket (86 panel) installed in the side by side rear vertical trough cabinet, this installation price slightly cheaper, but no control-cabinet compact and beautiful.

If not installed anti-static floor board, can directly in metope installation information socket, or on the ground uptick slot installation.

(1) work station terminal. Suggestions on wall decorate, socket &wooden workbenches. Installed in the metope panel

(2) machine cabinet server. Walk on by the front line mode, socket still installed in a cabinet or use distribution frames.
