(1.1 Overview of Smart Community At present, there are tens of millions of computers connected to the Internet, and hundreds of millions of people around the world conduct information exchange and various business management on the Internet. It has become the largest information center that can be shared globally/globally in the information age. The core of an intelligent community is an intelligent building. An intelligent building is a building with the characteristics of safety, high class, comfort, health and warmth, which is obtained through advanced design and strict construction after the integration of various technologies such as computer, communication, architectural art and image information. It covers intelligent automation, informatization, ecology and other aspects. Extend the intelligent building technology to several intelligent buildings in one area for comprehensive management, and then connect them hierarchically for unified management, and such an area becomes an intelligent community. ?? 1.1.1 The basic concept of intelligent community The concept of intelligent community is derived from the combination of building intelligent technology and modern residential quarters. As far as housing is concerned, the concepts of smart house, smart community and smart community have emerged successively. We can think of it this way: an intelligent residential area refers to building a comprehensive property management core, security system, information service in a residential area through an effective transmission network by using modern communication network technology, computer technology, automatic control technology, and IC card technology. The trinity residential community service and management integrated system, the property management system and the intelligent home furnishing system, enable the community and each family to achieve a safe, comfortable, warm and convenient living environment, and the ultimate goal is to enable each resident to meet their needs. the best solution. 1.1.2 Functions and attributes of intelligent residential areas The attributes of the integrated wiring system design of intelligent residential areas may include multiple residential buildings with irregular structures and shapes, including villas, multi-storey residential buildings and high-rise residential buildings. solution. Internal wiring should meet the needs of smart home use, including providing a complete set of technologies for unified control and management of home communication, home entertainment, home office, home security and other systems, supporting the comprehensive use of voice, data, images, and control. This design provides network design and design for Rainbow Smart Residential Community. The smart community is to divide the smart houses within a certain range and number into regions, implement unified management and control, pay more attention to the community services and community management that meet the needs of the residents, and have the value-added network communication function, which is the personalized development of the economic era. Foundation. Smart houses and smart communities represent three stages of people's demands for industrial control intelligence, home informatization and community networking. The community broadband network has laid the foundation for the realization of the three stages of the community, especially the information network service of the community. Intelligence focuses on the intelligent monitoring of the community, and informatization focuses on the information services of the community. Community information networking can be achieved through cable television networks, telephone lines and high-speed Ethernet, but from a practical point of view, the three are different in terms of network access methods, costs borne by users, and service content that can be provided. Ethernet has developed over the years and is widely used today. In today's rapid development of IT, how to choose excellent products and reasonable solutions is one of the primary problems faced by every Ethernet user. With the continuous enrichment of network usage, Ethernet not only needs to support more and more users, but also needs to support the increasingly complex topology of the network. In this situation, network design and system integration are facing increasing complexity and difficulty. It is necessary for users to consider adopting products from the same manufacturer and brand throughout the entire network. 1.2 Architectural Format Tianhong Community is a newly built intelligent community located in the center of the city.
