Planning a more reasonable integrated wiring system The integrated wiring system is a set of wiring systems specially designed to meet the needs of development. For a modern building, it is like the nerves in the body. It uses a series of high-quality standard materials to integrate voice, data, images and part of the control signal system with a unified transmission medium in a modular combination. After a unified planning and design, it is integrated into a standard wiring system, organically connects the three major subsystems of modern buildings, and provides a physical medium for the system integration of modern buildings. It can be said that the success of the structured wiring system is directly related to the success or failure of a modern building, and it is very important to choose a high-quality integrated wiring system. 1. The integrated wiring system can be divided into 6 independent systems (modules): 1. Work area subsystem The work area subsystem is composed of terminal equipment connected to the equipment between the information sockets. Including: information socket, socket box, connection jumper and adapter. 2. Horizontal area subsystem The horizontal area subsystem shall consist of information sockets for the work area, horizontal cables from floor distribution line equipment to information sockets, floor wiring equipment and jumpers. In general, 4 pairs of twisted-pair cables should be used for horizontal cables. Where the horizontal subsystem has high-speed applications, optical cables should be used, that is, optical fibers to the desktop. According to the requirements of the entire integrated wiring system, the horizontal subsystem should be connected to the wiring equipment in the secondary transfer room, transfer room or equipment room to form a telephone, data, television system and monitoring system, and manage it conveniently. 3. Management subsystem The management subsystem is set in the room of the floor distribution line equipment. The management room subsystem shall be composed of wiring equipment, input/output equipment, etc. in the handover room, and can also be applied to the equipment room subsystem. The management subsystem shall adopt single point management and double handover. The structure of the handover yard depends on the work area, the scale of the integrated wiring system and the selected hardware. When the management scale is large, complicated, and there are two-level transfer rooms, dual-point management and dual transfer are set up. At the management point, each termination field should be marked with a tag insertion bar according to the application environment. 4. The vertical trunk line subsystem is usually the main equipment room (such as computer room, program-controlled switch room) providing the most important copper or optical fiber trunk line in the building, and it is the information transportation hub of the entire building. Generally, it provides multiple connection paths between equipment rooms and wiring frames located on different floors, and can also connect large areas of a single-story building. 5. Equipment Room Subsystem The equipment room is a place where incoming equipment is set up at an appropriate place in each building for network management and management personnel on duty. The equipment room subsystem shall be composed of the building entry equipment, telephone, data, computer and other host equipment of the integrated wiring system and its security wiring equipment. 6. Building group subsystem The building group subsystem extends the cables of one building to the communication equipment and facilities of other buildings in the building group. It includes copper wire, optical fiber, and protection equipment to prevent the surge voltage of cables from other buildings from entering the building. 2. Integrated wiring system 1. Horizontal subsystem, cable usage calculation method: average cable length u003d (the farthest information point level Distance + the horizontal distance of the nearest information point)/2+2H (H-floor height) The actual average length of the cable u003d the average length of the cable × 1.1 + (termination tolerance, usually 6) the number of cables per box u003d cables per box Length/Average length of actual cables. Number of boxes required for cablesu003dtotal number of information points/number of cables in each box. Note: The horizontal distance of the farthest and nearest information point is the actual horizontal distance from the floor wiring closet (IDF) to the information point, including The actual distance of the horizontal route, if an IDF is set up in multiple layers, the height of the corresponding floor should also be included. The above 'average cable length' calculation formula is suitable for the situation of setting up a floor wiring closet (IDF) on one or three floors. 2. Backbone subsystem, copper cable usage calculation method: average cable length u003d (farthest IDF distance + nearest IDF distance) / 2 average actual cable length u003d average cable length × 1.1 + (termination tolerance, usually 6) Number of cable wiring per axis u003d cable length per axis/average length of actual cable number of required axes u003d total IDF/number of cables per box Note: The farthest and nearest IDF distance is from the floor wiring closet (IDF) The actual distance to the main distribution frame (MDF) of the network center mainly depends on the height of the floor and the horizontal distance from the weak current well to the equipment room (MDF). The number of large pairs of cables is calculated according to 1:2 (that is, 1 voice point is configured with 2 pairs of twisted pairs), and 25/50 pairs of cables are selected for reasonable design. 100 pairs of large pairs of cables are generally not to be selected because of the difficulty of construction. 3. Backbone subsystem, calculation method of optical cable usage: average length of optical cable u003d (farthest IDF distance + nearest IDF distance) / 2 average length of actual optical cable u003d average length of optical cable × 1.1 + (termination tolerance, usually 6) optical cable needs Total amount u003d total number of IDF × average length of actual optical cable Note: The farthest and nearest IDF distance is the actual distance from the floor wiring closet (IDF) to the main distribution frame (MDF) of the network center, which mainly depends on the height of the floor and the weak current well The horizontal distance to the MDF. If the number of fiber cores, single-mode, and multi-mode options are specified in the bidding documents, they should be designed according to the requirements. The general choice is 6-core multi-mode fiber optic cable.
