The meaning of integrated wiring: integrated wiring is a modular, highly flexible information transmission channel in buildings or between groups of buildings. It can not only connect voice, data, image equipment and switching equipment with other information management systems, but also connect these equipment with the outside. It also includes all cables and related connecting parts between the connection points of the external network or telecommunication lines of the building and the application system equipment.
Comprehensive wiring system function: It is designed for computer and communication wiring system.
â‘´ Transmission of analog and digital voices;
⑵ Transfer data;
⑶ Transmission of fax, graphics, and image data;
â‘· Transmission of video conference and security monitoring system information;
⑸ Transmit the information of building safety alarm and air conditioning control system.

The necessity of integrated wiring:
1. The integrated wiring system has good initial investment characteristics
1) The integrated wiring system accounts for the smallest proportion of network investment.
2) The investment characteristics of the integrated wiring system increase rapidly with the increase of the application system.
2. The integrated wiring system has a high performance-price ratio
1) Can solve changing user needs
2) Economies of scale.
3) The longer the use time of the integrated wiring system, the more fully its high-performance price ratio is reflected.
3. The cost of the integrated wiring system is low
The importance of integrated wiring
Integrated wiring is the foundation of modern networks. The use of integrated wiring is because:
â‘´ Can make the system structure clear, easy to manage and maintain.
⑵ Because the selected materials are unified and advanced, it is conducive to future development needs.
⑶ The system has strong flexibility and can adapt to various needs.
â‘· The integrated wiring system is easy to expand, while saving costs and improving the reliability of the system.
⑸ Comprehensive wiring as an open system is conducive to the integration of various systems.
The composition of the integrated wiring system
It is currently divided into 6 subsystems, summarized as "one, two, three subsystems". Work area subsystem, horizontal trunk subsystem, management area subsystem, vertical trunk subsystem, equipment room subsystem, building cluster subsystem.
Related standards of integrated wiring system
The main points of the integrated wiring standard
(1) Purpose â‘ To standardize a common cable wiring standard for voice and data transmission to support a multi-device, multi-user environment; â‘¡ To provide direction for the design of communication equipment and wiring products serving business; â‘¢ To be able to be used in commercial buildings Planning and installation of structured cabling, so that it can meet the various communication requirements of users; â‘£ establish performance and technical standards for the design and installation of various types of cables, connecting devices, and wiring systems.
(2) The scope standard refers to the "commercial office" communication system; the service life of the wiring system is required to be more than 10 years.
(3) Standard content Standard content is the media used, topology, wiring distance, user interface, cable specifications, connector performance, installation procedures, etc.
Characteristics of integrated wiring
(1) Compatibility. Primary feature
Definition: It is a completely independent, relatively independent of application system, and can be applied to the performance of multiple application systems.
(2) Openness.
Because it adopts an open architecture and conforms to various international standards, it is open to almost all products of famous manufacturers (such as switches); it is also supported by all communication protocols (such as ISO / EC 8802 -3, ISO / IEC 8802-5).
(3) Flexibility.
Reason: The use of standard transmission cables and related connectors for modular design. All channels are common.
(4) Reliability.
It uses high-quality materials and combined crimping to form a set of high-standard information transmission channels; all cables and related connectors have passed ISO certification; each application system uses the same transmission medium, which can be used as a backup for each other, which improves backup redundancy.
(5) Advanced nature.
The maximum bandwidth of the transmission channel composed of Category 6 twisted pair cables and related connectors is 250MHZ, and the maximum bandwidth of the transmission channel composed of optical cables and related connection components can reach 10GHz. With integrated wiring, voice, data, and video can be fully transmitted.
(6) Economical.
The mixed wiring method of optical fiber and twisted pair cable is used to form a complete set of information channels.
Comparison between the implementation process of integrated wiring and traditional wiring
Traditional wiring | Structured integrated wiring | |
1 Scheme design | Each system is designed independently, and there are too many constraints on the line. It is necessary to summarize the drawings multiple times to get a compromise solution, and the design cycle is long. | Comprehensive consideration of each system, the design idea is concise, and the design scheme can be changed conveniently and flexibly according to the needs of users, saving a lot of time |
2 Transmission medium | Different systems use different transmission media: | Use a unified transmission medium: |
3 Flexibility and openness | 1. Each system is independent and incompatible with each other, causing great inconvenience to users | 1. Users can flexibly manage various systems in the building |
4 scalability | 1. The rapid development of computer and communication technology makes it difficult for current wiring to meet future needs | 1. Fully adapt to the development of computer and communication technology within 15-20 years, laying a solid line foundation for office automation |
5 Construction | Each system is independently constructed, with a long construction period, resulting in a waste of personnel, materials and time | Uniform construction of each system, short cycle, save a lot of time, manpower and material resources |
China's standards can be divided into three categories: (1) Association standards (2) Industry standards, (3) National standards
Design level of integrated wiring system
According to the regulations in GB50311, the design of the integrated wiring system can be divided into three standard design levels: the lowest type, the basic type, and the integrated type.
Design principles of integrated wiring system
â— The network scale must not become smaller and smaller, nor can it become simpler. It is necessary to establish long-term planning ideas to ensure the adaptability of the system in a long time. Integrated wiring is pre-wired, and many product suppliers have a 15-year or 20-year warranty.
â— To create a comprehensive wiring system that can accommodate voice / data, technically, the needs of communication facilities, office automation, and building automation equipment can be included.
â— The number of installed wiring exceeds the current needs, and those extra outlets, ducts and cables will also come in handy in the future.
â— When establishing a new integrated wiring system, the structured integrated wiring standard should be adopted, and the agency standard cannot be adopted.
â— Use cables and wiring parts of the best material as much as possible.
â— Don't be too stingy about the installation cost. Even good quality components and cables need to be installed correctly.
â— The design should consider higher-speed technology to meet the future needs of users, and should not be limited to the technology currently in use.
â— The document is a link that should be noted in the integrated wiring system, and the complete document should be kept throughout the design and construction of the entire wiring system.
The basic principles of integrated wiring work usually have three points:
â‘ Ensure that the digital network is stable and smooth;
â‘¡Ensure that network use and management are easier, more transparent and cheaper;
â‘¢Ensure the flexibility and advanced nature of network configuration and have a long life cycle. Therefore, the physical layer of the network usually only involves a variety of cable media, and the most widely used are coaxial cables, twisted pairs and optical fibers.
