综合布线系统计算方法（Calculation method of integrated wiring system）Design method of integrated wiring system:1.1 understand the function of buildings according to owners(user) the requirements of the integrated wiring system are determinedConfiguration of integrated wiring system.1.2 according to the architecture, all intelligent systems are involved(communication network system, computerSystem, building equipment automation system and other weak electrical subsystems) transmission rate, bandwidth,Interface and other requirements to select the grade of the integrated wiring system(e.g.,Class c,D,E,F or lightcable).2 workspace designoffice(writeThe service area of the building work area can be divided into the following three types according to the office requirements.The first type is the area of service area in which the user terminal is more intensive5 6m2Make estimates. The second type is the usual working area of the users officeService area7 8m2Make estimates. The third type is the more spacious working conditionsThe area of service area can be pressed9 10m2Make estimates. Apartment and residential area service areaDomain can be according to room(study, living room, bedroom etc) each room can be divided1 workspace estimateThe service area of a working area of the department store can be pressed50m2To estimate. Everything elseType buildings are determined by the users nature and function.3.1 preliminary conditions for the design of the wiring subsystem3.1.1 the type requirements of the latest and forward terminal equipment are proposed according to the project;3.1.2 the number and location of the information sockets needed for each layer;3.1.3 comparison between one-time investment and installment plan;3.1.4 fromThe cable between FD and the information socket(horizontal cable, optical cable) the length should not be greater than90m requirements determine the location of each layer of weak current.Free learning website:http:/www.huipeng.com.cn/3.2 calculation of the number of information outlets3.2.1 calculate the total area of each layer (area) according to the plan of building project(there are no public corridors, elevator halls, staircases, bathrooms, etc).3.2.2 according to each layer(area) the area of the working area and the area of service of a working area are calculatedEach layer(area) number of work areas.Wn=SnPresent SbType in theWn to registerThe number of working areas of n layer (area)(take the integer value);Sn forN layer(areaTotal area of work area;Sb is the area of service for a working area.3.2.3 according to the selected integrated wiring system configuration standard and each layer(area) number of work areasMeasure out the layers(area) the number of information outlets.Tn= Wnx TnT is the firstThe number of information outlets of n layer (area); T for the number of a workspace information socket (minimum configuration of2).Tn= Tpm+ TdnThe Tpm is the firstN layer(area) support voice(the telephone) the number of information outlets;For the first TdnN layer(area) support data(computerThe quantity of the information socket;3.2.4. Calculate the information socket in the building according to the number of information outlets of each layer (area)The total number.N TnT =N = 1Type in theT is the total number of information points in the building;N is the number of layers of buildings.Free learning website:http:/www.huipeng.com.cn/Relevant technical data3.4 cable selection of wiring subsystemThe wiring subsystem is usually in copper core4 pair cable. Wiring sonThe system has high speed applications. Optical cable should be used. The wiring equipment cross-connection of the jumper should be selectedUse a combination of wire to connect the soft jumper wire. Use the double core jumper or the phone3class1 pair of cables.3.4 selection principle of information socket of wiring subsystemInformation points should be used8-bit modular general socket or cable socket.The number of mouth of information outlet panel has single mouth, double mouth, four hole or multi-port, etcAccording to the project, the number of the panel must be determinedType (i.e.,).3.5 wiring subsystem line designDetermine the cable line of the wiring subsystem(horizontal cable, optical cable) routing, root number, laying method and applicationSet requirements.3.6 calculation of cable usage of the wiring subsystem3.6.1 the horizontal cable of the distribution system
