Introduction to the name and implementation of the Integrated Wiring System

As we all know, the so-called integrated wiring system refers to the establishment and arrangement of communication lines of various systems in buildings (or buildings) in a standard, unified and simple structured manner, including network, telephone, monitoring, power supply and lighting systems. Therefore, the Integrated Wiring System is a standard and common information transmission system. More specifically, Integrated Wiring is a modular and highly flexible information transmission channel between buildings or buildings.

The so-called system integration refers to the separation of various devices (such as personal computers) through a structured integrated cabling system and computer network technology) functions and information are integrated into an interconnected, unified, and coordinated system to fully share resources and achieve centralized, efficient, and convenient management. System integration should adopt a variety of integration technologies, such as function integration, network integration, and software interface integration. The key to implementing system integration is to solve the interconnection and interoperability between systems. It is a multi-vendor, multi-protocol and application-oriented architecture. All integration-oriented problems related to subsystems, building environments, construction coordination, organization management, and staffing need to be solved for interfaces, protocols, system platforms, and application software between various devices and subsystems..

From the definition of the two, the integrated wiring system can provide a connection channel of practical significance for each subsystem of the system integration. However, according to the actual application, the Integrated Wiring System is mostly used as a transmission channel for voice and data, while the wiring of building automation systems and security systems is still independent, this is not in line with the name of Integrated cabling. That is to say, in the current smart buildings, Integrated Wiring is actually not a real name. However, with the increasing demand for the integration of smart buildings, the Integrated Wiring System is required to be more closely integrated with building automation systems and security systems.

As the most basic and important component of smart buildings, building automation systems are highly automated integrated management and control systems built using computers and their network technology, automatic control technology, and communication technology. Through BAS, multiple devices in the building can be connected to a control network for unified control, including air conditioning, lighting, elevator, fire fighting, security and other equipment. It ensures the comfort and safety of the building environment, while achieving efficient and energy-saving.

BAS has many related technologies and standards, among which Lonworks, BACnet, and EIB have been widely used. However, with the development and maturity of Ethernet technology, its application fields become more and more extensive. Along with the successful application of Ethernet technology in the industrial control field, Ethernet technology will penetrate into the BAS field more and more. At present, Ethernet has gained many applications in some newly developed systems. The popular solution is to integrate air conditioning, lighting and other systems into Ethernet through the parameter control module, 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 can be.

When Integrated Wiring is dominated by five categories of products, it mainly supports 10 MB and MB networks, while for broadband videos such as cable TVs, the performance is weaker than that of coaxial cables. However, with the emergence of more than five and six categories of products, the Integrated Wiring System has begun to carry more and more applications with high transmission rates. At present, many wiring manufacturers, such as Commscope and rihai SILK, have launched 10 Gigabit copper cabling, especially 10 Gigabit unshielded systems. This ensures video transmission. In fact, the latest research found that broadband videos can also be transmitted through 6 types of systems and get very good image quality, which laid the foundation for the increasingly close combination of wiring products and BAS applications.

The transmission performance of the six types of cabling systems can reach 250 MHz. A higher signal-to-noise ratio means that the six types of systems are not easily affected by the transceiver and other environmental factors, slowing down the network, this provides good data throughput, reduces the error rate, and provides a possibility for video applications. The results show that over five systems can transmit 38 channels of video at a distance of 100, and 6 systems can transmit 54 channels of video at a distance of 100. One of the major advantages of running videos on twisted pair wires is that multiple channels can be transmitted at the same time only using one pair of four pairs, and two pairs can be used for Bidirectional video transmission, it also has the ability to transmit video and telephone signals simultaneously on a single cable, combined with data applications, truly achieving multi-network integration.

In this way, the application of the Integrated Wiring System is much richer, and the cost of separately wiring videos in smart buildings can be reduced, it provides higher stability for transmission of security monitoring systems and video conferencing systems. I believe that with the maturity of the 10 Gigabit unshielded system, the name of Integrated Wiring will gradually become a reality.
