1. Today's community construction and development needs
· General telecom service requirements: ISDN, ADSL, DDN and other services;
· Information business requirements: high-speed Internet access, distance education, telemedicine, conference video, video on demand, online information, shopping, entertainment, etc.;
Residential automation management: remote meter reading and metering of water and electricity meters, remote control of household appliances, etc.;
· Community safety management: automatic alarms are implemented for residential fires, harmful gas leakage, etc., through closed-circuit security in the residential area, and the residential emergency call system can realize inter-building calls, emergency calls and other functions;
· Community internal information construction: community internal information website, providing users with internal video services, internal community announcements, housekeeping service information, etc.??SPAN lang=EN-US>
· Community property management: automatic fee collection, vehicle parking space management, user information, housing information, street lights and other public facilities management, etc.
2. Community Information System Design Principles
· The central computer room of the community uses Gigabit Ethernet switches and Layer 3 routing; the uplink uses Gigabit optical ports, and the downlink uses 100M optical ports or electrical ports. Ethernet switches are used on the floor, using 100M optical ports or electrical ports for uplink and 10/100M electrical ports for downlink.
· Use outdoor optical fiber (multi-mode/single-mode), or Category 5 outdoor cable (4 pairs/25 pairs), or use hybrid optical fiber (optical fiber + Category 5 cable + DC remote power supply line) from the center of the community to each building.
· The floor exchange equipment is connected to each household by using ??SPAN lang=EN-US> Category 5 4-pair line.
· The home cable adopts 2 Category 5 4-pair cables (one is for network, the other can provide 4 telephone lines).
· Considering the realization of TV Internet access through coaxial cable in the future, a 75-ohm bidirectional coaxial cable should be added to the household cable.
· Connect the home cable (category 5 cable, coaxial cable) to the home network communication box; in addition, connect all the information sockets (computer, telephone, TV) in the room through the cable (category 5 cable, coaxial cable) centrally Enter the home information wiring box.
3. Integrated wiring standards at home and abroad
· ISO/IEC11801 (1995) (International) EN50173 (Europe)
· EIA/TIA568A (1995) (North America) TIA/EIA-570A (North American home wiring)
· YD/T926 (1999) (China)
· AXSI/TIA/EIA570A "Home Telecom Wiring Standard"
· ISO/IEC11801:1995(E) "Information Technology - Integrated Wiring of User Houses"
· The star classification standard of intelligent community promulgated by the Ministry of Construction of China in 1999
In September 1998, the American National Standards Committee (ANSI) and the TIA/EIA Association and the updated home wiring standard, and re-designated as ANSI TIA/EIA-570A-Residential Telecommunications Cabling Standard (Residential Telecommunications Cabling Standard) to set the level of home wiring .
Approved media include optical cable, coaxial cable, Category 3 and Category 5 Unshielded Twisted Pair Cable (UTP) The length of the link from the socket to the distribution box should not exceed 90 meters (295 feet), and the length of the channel should not exceed 100 meters (328 feet) . Wiring for fixtures such as walkie-talkies, fire sensors will be included.
The standard content proposes a new level of wiring and establishes a basic specification and standard for wiring media. The main applications support services such as voice, data, image, video, multimedia home automation system, environmental management, security, audio, TV, probe, alarm and walkie-talkie.
Level 1: Provides a general-purpose cabling system that meets the minimum requirements for telecommunication services. This level can provide telephone, CATV and data services. Class 1 mainly uses twisted pair and uses the star topology method to connect. The minimum required class for class 1 wiring is CATV and a four-pair unshielded twisted pair (UTP), and must meet or exceed ANSI/TIA. /EIA-568-A requirements for transmission characteristics of three types of cables; and a 75 ohm coaxial cable (Coaxial), and must meet or exceed the requirements of SCTE IPS-SP-001, it is recommended to install five types of unshielded twisted pair cables (UTP) for easy upgrade to level two.
Level 2: Provides general cabling systems for basic, advanced and multimedia telecommunications services, this level supports current and developing telecommunications services. The minimum requirement for Class II cabling is one or two four-pair unshielded twisted pair (UTP) and must meet or exceed the Category 5 cable transmission requirements specified in ANSI/TIA/EIA/-568-A, and one or two A 75 ohm coaxial cable (Coaxial) must meet or exceed the requirements of SCTE IPS-SP-001. Optional fiber optic cable and must meet or exceed the transmission characteristics requirements of ANSI/ICEA S-87-640.
4. Smart Home Wiring Overview
In today's society, people have been fully integrated into a rapidly changing information age; in other words, people are not only inseparable from the demand for information when working in the office, but also because of the rapid development of technologies such as ISDN, ADSL, Internet and automatic control. Development is bringing great changes to people's daily home life. People's requirements for home are no longer limited to food and clothing, but to the comfort of life, that is, the automation of home equipment and cultural atmosphere (education, entertainment, communication with the outside world) Contact) put forward higher requirements, and the concept of Intelligent Home Systems (IHS) came into being.
In order to meet the needs of modern home for voice, data and image communication, the company has adopted TONGTONG's smart home wiring system to provide a successful solution for the communication network of intelligent buildings. All the points in the building are designed in accordance with the international and domestic smart home wiring system standards, with a high degree of flexibility and reliability, saving user investment to the greatest extent.
