Talking about the name and reality of the integrated wiring system

The integrated wiring system is a standard general information transmission system. More precisely, integrated wiring is a modular, highly flexible information transmission channel between buildings or building blocks.

As we all know, the so-called integrated wiring system refers to the standard, uniform and simple structured way to prepare and layout of buildings (or buildings) of various systems of communication lines, including networks, telephones, monitoring, power supply and lighting systems. Therefore, the integrated wiring system is a standard universal information transmission system. More precisely, integrated wiring is a modular, highly flexible information transmission channel between buildings or building blocks.

and the so-called system integration, is through the structure of the integrated wiring system and computer network technology, the separation of equipment (such as personal computer), functions and information integrated into the interrelated, unified and coordinated system, so that resources to achieve full sharing, to achieve centralized, efficient and convenient governance. System integration should adopt the integration technology of function integration, network integration and software interface integration. The key to the implementation of system integration is to solve the interconnection and interoperability problems between systems, which is a multi-vendor, multi-protocol and application-oriented architecture. This requires solving all the integration-oriented issues related to subsystems, architecture environment, construction coordination, organizational governance and staffing of various devices, subsystems, interfaces, protocols, system platforms, application software, etc.

According to the definition of the two, the integrated cabling system can provide practical connection channel for each subsystem of system integration. However, from the current practical application, the integrated wiring system is more as a voice and data transmission channel, and building automation systems and security systems, such as the wiring is still independent, this and comprehensive wiring of the "comprehensive" name is somewhat inconsistent. In other words, in the current intelligent building, integrated wiring is in fact a misnomer. However, with the increasing requirements for the integration of Intelligent building, the integrated wiring system is required to be used in conjunction with building automation systems, security systems, and more closely.

As the most basic and important part of intelligent building, the building automation system is a highly automated comprehensive control system which is constructed by computer and its network technology, automatic control technology and communication technology. BAS can connect a variety of equipment within the building to a control network for unified control, including air-conditioning, lighting, elevators, fire and security and other equipment. It ensures the comfort and safety of the environment within the building, while achieving high efficiency and energy efficiency.

BAS has a lot of relevant technology and standards, including LonWorks, BACnet, EIB and so on have been widely used. But with the development and maturity of Ethernet technology, its application is more and more extensive. With the successful application of Ethernet technology in the field of industrial control, Ethernet technology is bound to penetrate the BAS field more and more. At present, in some newly developed systems, Ethernet has been a lot of applications, the more popular scheme is that air-conditioning, lighting and other systems through the parameter control module integrated into the Ethernet, and the system with RS-232 or RS-485 interface through the Gateway conversion module can also be integrated into the Ethernet, IP Phone and IP camera is more convenient, directly connected to the Ethernet on it.

In the integrated wiring to 5 types of products, mainly to meet the 10MB and 100MB network, and for the hosting of broadband video (such as cable TV) in performance is weaker than coaxial cable. However, with the advent of Super 5 and 6 products, the integrated wiring system is also starting to carry more and more high transmission rate applications. At present, many wiring manufacturers (such as Kombucha commscope, silk, etc.) have launched the million-gigabit copper cabling (especially the Wan Shaofei shielding system), which provides a guarantee of video transmission. In fact, the latest research found that broadband video can also be transmitted through 6 types of systems and can get very good image quality, which is the wiring products and BAS more and more close application of the combination laid the foundation.

6-Class cabling system transmission performance of up to 250MHz, higher signal-to-noise ratio means that 6 types of systems are not easily affected by transceivers and other environmental factors to slow down the network, thus providing a good data throughput, reduce the BER, for video applications to provide the possibility. The results show that the Super 5 system can transmit 38 channel video simultaneously at 100 meters distance, and 6 kinds of systems can transmit 100 channel video simultaneously at 54 meters distance. One of the great benefits of running a video on a twisted pair is that you can propagate multiple channels at the same time using only a pair of four pairs. can also be used two pairs of two-way video transmission, and the ability to be in a cable at the same time transmission of video and telephone signals, combined with data applications, really do a multiple network integration.

As a result, the application of the integrated wiring system is much richer, also can save the intelligent building for the video separate wiring cost, for security monitoring system and video conferencing system transmission provides a higher stability. Believe that with the maturity of Wan Shaofei shielding system, integrated wiring of the "comprehensive" name will gradually become a reality.
