1、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 archite
2、cture, 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
3、 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
4、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 r
5、oom 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 o
