In-depth analysis of the Integrated Wiring System Design Scheme

There are still many things worth learning about integrated wiring systems. Here I will explain the requirements analysis, system functions, system design basis and design principles of integrated wiring systems, I hope you will have a better understanding of the Integrated Wiring System.

With the rapid development of computer networks and communication technology, the construction industry in the 21st century will also undergo huge changes. intelligent buildings have become synonymous with high-tech buildings, the improvement of people's living conditions and office environments undoubtedly puts forward newer and higher requirements for building intelligence, the Integrated Wiring System is a network wiring system that supports Voice/Data/graphics and Image Applications selected by users. It provides a perfect physical connection platform for intelligent implementation. When the system is configured to adapt to more advanced technical needs and meet the rapid pace of change, the long-term investment of the building will be controlled to a minimum.

I. Requirement Analysis
The Integrated Wiring System is the Information Network Basis of the hotel's intelligent system. This design focuses on the quality, scientific, advanced, reliability and security of the system, and is easy to expand. At the same time, this design takes into account the hotel's application characteristics, future development needs. Therefore, in system design and product selection, focus on the quality of cabling products, modularization of cabling systems, and security, manageability, and maintainability of the systems.
The purpose of the hotel Integrated Wiring System is to provide guidance based on system specifications and support the current world-leading Integrated Wiring technology, computer technology, communication technology, and automation technology, A unified planning and highly integrated wiring system is established to provide unified transmission lines, equipment interfaces, and high-quality Transmission Performance for the data, images, and control signals of the hotel computer network system. The intelligent and integrated communication, office, and management methods of hotel computer communication networks are fully realized, build the hotel's computer communication network into a network platform featuring a high starting point, high standards, first-class functional facilities, high openness, smooth upgrade, and smooth upgrade. At the same time, the cabling system meets the future development requirements of the computer network system and provides a 15-year guarantee. When a new system is added to the hotel building, it provides signal transmission support for new equipment.
As the basic platform of the hotel Intelligent System-Integrated Wiring System will provide high-quality transmission channels for the hotel's voice communication, broadband data, image networking, hotel management system and website construction. The functional areas in the hotel building are connected by a high-performance structured cabling system to form a high-bandwidth, structured information highway.

Ii. system functions
The integrated wiring system proposed in this design realizes the interconnection between the network physical layer of Hotel Equipment and meets the requirements of information sharing between systems, it establishes infrastructure for centralized hotel management and connection to the Internet. Specifically, the integrated wiring system designed in this scheme can support the following applications and devices.
Voice: programmable switches, telephones, faxes, satellite communications, teleconference, and voice mailboxes.
Data: Fast Ethernet, Gigabit Ethernet, 1.2 GATM, TCP/IP, INTERNET, and INTRANET.
Video: closed-circuit television monitoring, video conferencing, visual text, automatic control, and other audio, video, and control signals.
It should be pointed out that video, RF, public broadcasting, automatic control, and other system technical aspects, the Design Theory and Practice of multiple projects have proved that the structured cabling system can achieve the same transmission quality and transmission distance as the traditional cabling method. However, in terms of engineering cost, because the structured cabling system must be equipped with dedicated adapters, and the project cost will be greatly improved, this design only provides high-performance transmission links. When the technical development cost is reduced, or provide solid support when there is such a need.

Iii. System Design Basis and design principles
Intelligent hotel system engineering-Integrated Wiring System Engineering the entire integrated wiring system uses a star structure, from the socket to the floor distribution frame, and finally connects to the corresponding data and voice data center through the data/Voice trunk cable, to facilitate centralized management. The system data center is set on the first floor of the hotel. Horizontal System cabling meets the requirements for cabling less than 90 meters. The horizontal part of the data is transmitted using cat5e twisted pair wires, the horizontal part of the speech is transmitted using telephone lines, the trunk subsystem is transmitted using optical cables, and the trunk subsystem is transmitted using a large logarithm cable. If the structured Integrated Wiring System is regarded as an information highway, the more advanced the road condition, the faster the vehicle speed can be improved. This kind of high speed rate is not achieved by improving the grade of the car alone, but by building an information-based Benz "road" smoothly and quickly. This design not only meets the user's current application environment, but also supports the next 21 st century high-speed broadband applications.

In order to meet the hotel's current and future application development in the next 10 to 15 years, and may choose different adapters based on different models to build the entire computer network. Therefore, an Open Integrated Wiring System is used as a solution. The structured cabling system adopts a star structure to implement various network logical topologies.

1. Design Principles
1) advanced nature. The design goal of the Integrated Wiring System determines that the system must adopt advanced methods and equipment, that is, to reflect the current level and have the potential for development. Because the Integrated Wiring System is a project that is put into operation within a specified period of time, the technology involved in the system must be mature and advanced.
2) openness. The Integrated Wiring System should be open. On the one hand, the Integrated Wiring System can adapt to different functional requirements, while supporting the corresponding equipment of different manufacturers.
3) practicality. The Integrated Wiring System can adapt to the development of technology in the present and future to achieve data and voice communication.
4) flexibility. The Integrated Wiring System should be able to meet flexible and general requirements.
5) modular. In the Integrated Wiring System, all the connectors except cables fixed in buildings are modular standard parts.
6) scalability. The Integrated Wiring System must be scalable so that devices can be easily expanded in the future.
