What are the elements of integrated wiring and home wiring?

Comparison between Integrated Wiring and Traditional Wiring

A, the definition of integrated wiring:

The full name of integrated wiring is "building structured integrated wiring network", which is divided into "integrated wiring system" according to its function. It is an integrated wiring system that meets the needs of future ISDN. The wiring system is specially designed for the demand of high quality.

The materials with standard quality adopt the combined crimping method, which makes them easy to be combined into a complete wiring system. Generally, twisted pair can transmit voice, data and image signals, and can be connected to computer networks such as IBM, WANG, IBS, DEC and security reports.

The police monitoring system uses optical cable and high-quality twisted pair to transmit high-speed data and high-precision images, which conforms to the future FDDI (Optical Fiber Distributed Data Interface) transmission medium standard.

Second, the composition of the integrated wiring subsystem:

Integrated wiring consists of six independent subsystems:

1) Park realizes the wiring system connection between buildings in the building complex.

2) The equipment subsystem realizes the connection between the wiring system and the equipment. Mainly to cooperate with adapters related to different devices.

3) trunk line (riser; Backbone subsystem realizes the connection between computer equipment, PBX and various management subsystems. The common communication medium is optical fiber, which can realize FDDI technology and make the transmission rate of the system reach 100MBPS.

4) The management subsystem (administration) realizes wiring management and has perfect design. It is color-coded, easy to track and jump, and saves 50% space compared with the traditional junction box.

5) The horizontal subsystem realizes the connection between the information socket and the management subsystem (jumper frame), which is usually realized by three types of twisted pair and super five types of twisted pair. This project adopts super five types of unshielded twisted pair.

6) Workspace subsystem. Commonly used equipment includes computers (PC, workstation, mid-range, printer), telephones, fax machines and other equipment.

Three. Integrated wiring investment projects:

3. 1 transmission medium

Twisted pair of all wiring subsystems. It can transmit data, sound and image signals.

Optical fiber is mainly used in buildings and trunk subsystems. High security, low distortion and large capacity.

3.2 Distribution frame

The distribution frame is well designed, color coded, easy to track and jump, and small in size, saving 50% space compared with the traditional junction box. Quick connect jumper is easy to manage and maintain.

Optical cable junction box-modular structure, easy to expand plug-in coupling device, making connection easy.

3.3 standard information socket

There are many models such as embedded, surface type, double hole and single hole, which are suitable for surface or ground installation of wall furniture.

Standard RJ45 8-core wiring conforms to ISDN standard.

At the same time, the workspace socket has six characteristics:

A) Built-in dustproof door to prevent dust and moisture;

B) Easy-to-identify signs, through which users can successfully identify the types of data signals;

C) provide cable binding holes to fix cables;

D) Through-hole technology to ensure transmission without damage;

E) Color module, where different colors represent different functions and quickly identify different applications;

Fourth, the comparison between integrated wiring and traditional wiring

The concept of traditional wiring

In traditional wiring methods, high voltage is mostly considered in civil engineering design, and telephone is only considered in weak current at most, not computer system. The wiring problem is often considered when establishing a computer system, which leads to secondary or even multiple constructions. However, different computer manufacturers use different materials in their networks, which greatly limits the expansion of the system and the interconnection between different systems.

Because the computer system often adopts the open wire method, the office environment is extremely chaotic, which reduces the stability of the computer system and is extremely difficult to maintain and manage. An enterprise is often equipped with a huge information department to ensure the normal operation of the system.

In order to unify the wiring system in buildings, the American Electronics Industry Association (EIA) has formulated the wiring standards for commercial buildings, namely EIA/TIA 568 and 569 and other related standards. This standard has formulated corresponding specifications for the following aspects:

System structure of cable laying in commercial buildings: mainly refers to the cable system required by information system.

The function and structure of each subsystem of the wiring system are defined.

The performance indexes of materials and devices used in each subsystem are defined, such as attenuation, transmission distance, noise and signal crosstalk.

Specify the users of each subsystem and their relationship with architectural design.

Adopting a structural wiring system means:

* Reduce maintenance costs

* Network cabling system can be carried out at any design level.

* Re-layout or equipment relocation can be completed in a limited time and the cost is very low.

* Modular design of system structure, which is convenient for future technology update and application expansion.
