The operation and maintenance mode of the leased office building integrated wiring system is generally property management, and the project is also invested and built by the developer himself. Specific methods to determine the construction scale and project implementation process: one is the conventional project scale prediction, that is, a work area is set every 5 ~ 100 m2, and each work area is set with two or more information points, and then the equipment configuration of the whole horizontal and trunk subsystems is considered according to this basic number and network structure. The other is because the users of rented office space are uncertain, which is temporary and mobile. For the temporarily rented site, the concept of regional wiring is adopted for design:
1. First, lay the optical (electric) cable from the telecom room to the area (where the major customers are located), and each area can be equipped with two optical fiber sockets (connected to the Ethernet switch) and two voice sockets (connected to the enterprise telephone hub or the program-controlled subscriber telephone switch); After the distribution network in the area is settled by the customer, it will be completed by itself as needed.
2. Set CP points (assembly points) in the wiring of horizontal cables. First, lay the horizontal cable from the telecom room to the CP point, and then complete the cable from CP to the information point according to the user's own needs.
3. Establish multi-user information sockets in the area.
4. Even you can only do the trunk part of the cable, not the horizontal part, and reserve the corresponding duct in advance, and then wire it according to the network construction after the user determines it.
For the leased office building, the wiring system can adopt the integrated wiring form of super 5 (voice) and 6 (data) optical fiber (horizontal or trunk) mixed configuration.
For the office building for personal use, especially the office building of state government agencies, because its network is divided into internal network, external network and security network, integrated wiring is not a system. Information points should include not only telephone and data requirements, but also information points related to intranet, extranet, secure network and backup. In this way, there are more information points for general projects. In addition, the installation site, conduits and cables of integrated wiring equipment should be physically isolated. For some confidential projects, integrators can only implement the horizontal wiring part, and the main part will invite institutions with safety qualifications or national authorization. Generally, the level of integrated wiring used in self-occupied office buildings is relatively high, such as the full configuration scheme of six types of optical fibers.
In addition, it should be mentioned that for the open office area, in order to facilitate the laying of a large number of horizontal cables, it is more favorable to use the network floor laying method, but at this time, it is necessary to consider whether the cables are laid with metal pipes to meet the corresponding requirements.
Media buildings include medium-sized and above theaters and radio and television services. Its integrated wiring system should meet the needs of information application of media business and information management of media buildings.
Due to the high requirements on the frequency and field strength of audio/video transmission information flow in media buildings and the existence of many radio interference sources, shielding and optical fiber integrated wiring systems are often used to avoid interference between transmission line signals and electronic equipment.
For the media part, because there are more image signals to be transmitted and more coaxial cables are used, it is best to consider the construction of integrated pipelines when laying pipe slots, especially pay attention to the spacing requirements between different information service signals (with emphasis on the distance from broadcast lines).
People in the theater are basically mobile, so there are not necessarily many information points; However, buildings such as radio and television have the characteristics of professional production and should mainly meet the technological requirements.
At present, according to the provisions in the Design Standard for Intelligent Buildings GB/T503 14-2006, the types of buildings can be divided into ten categories: office buildings, commercial buildings, cultural buildings, media buildings, sports buildings, hospital buildings, school buildings, traffic buildings, residential buildings and general industrial buildings. Therefore, when formulating the implementation plan of intelligent building system, we should give consideration to "* * *" and "personality", and we should not confuse and blindly copy them. As the "* * *" part of the engineering scheme design of the integrated wiring system, it should comply with the provisions and requirements of the Code for Engineering Design of Integrated Wiring System (GB 5031KLOC-0/-2007), and the "personality" part should be analyzed, measured and improved according to the designer's characteristics and engineering needs. Let's interpret the problems that should be paid attention to and considered in the engineering design of the integrated wiring system of these ten types of buildings.
