Understanding integrated wiring and integrated wiring systems (1)

I. Overview

Integrated Wiring is a modular and highly flexible information transmission channel between buildings or buildings. It connects voice, data, Image devices, and exchange devices to other information management systems, as well as external devices. It also includes all cables and related connection components between the connection points of the external network or telecommunication lines of the building and the application system equipment. Integrated Wiring consists of components of different series and specifications, including transmission media, related connection hardware (such as distribution frame, connector, socket, plug, adapter) and electrical protection equipment. These components can be used to build various subsystems. They have their own specific purposes, which are not only easy to implement, but also can be smoothly upgraded as demand changes.

1. The development process of Integrated Wiring

Looking back, the development of integrated wiring is closely related to the building automation system. Traditional cabling, such as telephone and computer LAN, are independent of each other. Different systems are designed and installed by different manufacturers. Traditional cabling uses different cables and different terminal sockets. Additionally, the plug, socket, and distribution frame connecting these cables are not compatible with each other. The office layout and environment change often occurs. You need to adjust the office equipment or change the wiring when changing the equipment as the new technology develops. This leaves Unused old cables due to the addition of new cables, which takes a long time, resulting in a pile of messy cables in the building, causing a great risk. The maintenance is inconvenient and the transformation is very difficult.

With the development of global social informatization and globalization of the economy, people's demand for information sharing becomes increasingly urgent. Therefore, a wiring scheme suitable for the information age is needed.

After years of research, researchers at the Bell lab at AT&T successfully tested office buildings and factories, at the end of 1980s, the company was the first to launch the SYSTIMATMPDS (Integrated cabling system for buildings and buildings). Now, it has launched the Structured Cabling System SCS. According to the national standard GB/T50311-2000 of the People's Republic of China, it is named as the Integrated Wiring GCS (Generic cabling system ).

Integrated Wiring is a type of pre-wiring that can meet the needs of a long period of time.

2. Features of Integrated Wiring

Compared with traditional cabling, integrated cabling has many advantages that cannot be compared with traditional cabling. It features compatibility, openness, flexibility, reliability, advancement, and economics. In addition, it brings a lot of convenience to people in terms of design, construction and maintenance.

(1) compatibility: The primary feature of Integrated Wiring is its compatibility. Compatibility means that it is completely independent of the application system and can be applied to multiple application systems.

In the past, for voice or data line cabling in a building or a complex, cables, distribution sockets, and connectors produced by different manufacturers were often used. For example, the User Switch usually uses twisted pair wires, and the computer system usually uses coarse or fine coaxial cables. Different devices use different wiring materials, and the plug-ins, sockets, and terminal boards connecting these different cables are also different and incompatible with each other. Once the terminal or telephone location needs to be changed, new cables and new sockets and connectors must be installed.

Integrated Wiring uniformly plans and designs the signal lines of voice, data, and monitoring devices, and uses the same transmission media, information sockets, communication devices, and adapters, integrate these different signals into a set of standard cabling. It can be seen that such wiring is much simpler than traditional wiring, saving a lot of materials, time and space.

During use, you do not need to define the specific application of an information outlet in a work zone. Instead, you can just insert a certain terminal device (such as a personal computer, phone number, or video device) into the information outlet, then, connect the management room to the device, and connect the device to the system.

(2) Openness: for traditional cabling methods, as long as the user selects a certain device, the appropriate cabling mode and transmission media are selected. If another device is replaced, all the original wiring will be replaced. This change is very difficult for a finished building and requires a lot of investment.

Because Integrated Wiring adopts an open architecture and complies with various international standards, it is open to almost all famous manufacturers' products, such as computer equipment and switch equipment; and all communication protocols are also supported, such as ISO/IEC8802-3, ISO/IEC8802-5 and so on.

(3) Flexibility: the traditional cabling method is closed and its architecture is fixed. It is difficult and difficult to migrate or add equipment, or even impossible.

Integrated Wiring adopts standard transmission cables and related connection hardware, and is modular. Therefore, all channels are common. Each channel supports terminals, Ethernet workstations, and card ring network workstations. You do not need to change the wiring of all devices. You only need to increase or decrease the corresponding application devices and perform necessary jumper management on the distribution frame. In addition, the networking can be flexible and diverse. Even in the same room, there can be multiple user terminals. Ethernet workstations and licensing Ring Network Workstations coexist, providing users with the necessary conditions for organizing information flows.

(4) Reliability: Due to the incompatibility of various application systems, traditional cabling methods often require multiple cabling solutions in a building. Therefore, the reliability of the building system should be ensured by the selected wiring reliability. When the cabling of various application systems is not successful, cross interference may occur.

Integrated Wiring uses high-quality materials and combination crimping to form a set of high-standard information transmission channels. All groove and related connectors have passed ISO certification. Each channel must use special instruments to test the link impedance and attenuation rate to ensure its electrical performance. All Application System Wiring uses point-to-point connections. Any link failure does not affect the operation of other links. This facilitates the operation and maintenance of links and troubleshooting, this ensures the reliable operation of the application system. Various application systems often use the same transmission media, so they can be used as backups, improving Backup Redundancy.

(5) advanced: Integrated Wiring uses fiber and twisted pair wires to form a complete set of cabling reasonably.

All cabling adopts the world's latest communication standards, and the links are configured with eight-core twisted pair wires. The bandwidth of Category 5 twisted pair wires can reach 100 MHz, and that of category 6 twisted pair wires can reach 200 MHz. For special users, Fiber cables can be directed To The Desk ). Some Optical Cables and data cables are used for voice trunk lines to provide sufficient bandwidth for simultaneous transmission of multi-channel real-time multimedia information.

(6) Economy: compared with traditional wiring, Integrated Wiring has economic advantages. The main integrated wiring can meet the needs of a long period of time. It takes a lot of time to transform traditional wiring, the loss caused by delayed work is even more difficult to calculate with money.

According to the above discussion, Integrated Wiring can better solve many problems existing in the traditional wiring method. With the rapid development of science and technology, people have increasingly urgent requirements for information resource sharing, in particular, communication networks dominated by telephone services gradually transition to Integrated Service Digital Networks (ISDN), and pay more and more attention to integrated communication networks that can simultaneously provide voice, data, and video transmission. Therefore, Integrated Wiring replaces a single, expensive, and complex traditional wiring. It is a requirement of the "Information Age" and an inevitable trend of historical development.
