【 Weak current College 】 intelligent community composition and level of

Intelligence community is to have a certain degree of intelligent housing community in General. Refers to the adoption of comprehensive configuration residential areas of functional subsystems, and cabling, the network will be a certain geographical area of housing, as well as the implementation of the various public facilities in the area of intelligent management of collection service to community needs, to provide safe, comfortable, convenient, energy saving and sustainable development of living environment. Intelligent community there are three important components that focus on the future of broadband data intense growth needs access transmission network to ensure domestic safety and automation capabilities of domestic intelligence network Terminal, as well as provide diversified information services and Park in the center of public property management.

Compare with smart buildings, smart community basic objective is to reach people and architectural and environmental symbiosis and common prosperity, more focused on meeting the household in security, living environment of comfort, convenience of community services and community management, has the effect of the proliferation of network communications, and other aspects of the implementation of and the demand for personalized (Ergonomics). How community features, gives the community a variety of features to meet the needs of the community, and in building intelligent format and has its own characteristics, this is a smart community should pursue.

From a general sense, intelligent community standards should meet the following requirements:

(1) to provide "local residents comfort, security, convenience" family living space, "people-oriented" and "energy saving is the first" and "environmental priority" principle is the focus of intelligent design; security and network traffic is a smart community's main features.

(2) has the information freeways family entrance, there is a fast, comprehensive information exchange;

(3) provides a rich and high-quality cultural and recreational life; including children's education, adult education, multi-level family and education services;

(4) provides for family health, tele-care services.

(5) community of property management to "efficient and thoughtful," as the goal, to a greater extent to meet the needs of local residents, service to the residents.

First, the intelligent community structure and function of

Community of intelligent system can be divided into domestic intelligence system, network wiring and management centre of the three-tier structure. Family inclusive family of intelligent control of all functions with new technology to streamline operations and convenience to users, improving the system of intelligent; the construction of network wiring, three are closely integrated into a unified intelligent network, and take fully into account the future demand for broadband; intelligent community integrated management center is a community of Intelligent Network Management Center, is the Community area and wide area networks connected to the channel.

To a certain extent, can be considered intelligent community = residential buildings of intelligent + community network. What grade of cabling systems and communication networks both hardware platform that is both a community building in one of the major investment, is also an important evaluation community. Especially on the community's forward-looking communication network required, otherwise it may cause a step failure will always lag behind embarrassing situation.

Intelligent Community system structure has the following characteristics: first use of advanced, standards-compliant technology and equipment; at the same time all of the system are distributed is structured, with scattered individual households in the terminal or device, through the network to a management or control center, the Center provides public information resources, or to individual households provide centralized security monitoring; and finally, all the intelligent system can be independent and in computer network based on centralized management.

Intelligence community's basic functional block diagram shown in figure a, including security, communication networks and three function block for property management and, through the integrated wiring subsystem will these three functional blocks and even become a system.

1. intelligent community has its integrated wiring subsystem.

Community intelligence system has three main platforms, intelligent home wiring intelligent community of the physical platform, computer network technology is the intelligence community's technology platform. Whereas the community choose the fieldbus is the intelligent community of application platforms. Control of residential equipment have CEBus, Profibus, LonWorks, and other types of BACnet. Intelligent system integration level and the selection of the closely related field bus, particularly affect community intelligence system integration capabilities of scalability.

Community achieve intelligent can have different programmes and approaches. One is the use of telecommunication lines, one is the use of cable TV networks, and then a bus system is the adoption of the community. Community bus system is the first establishment of the community's regional network, to connect several subsystems, and regional network with the public network.

Intelligent Community adopts comprehensive wiring design, should comply with smart home wiring standard TIA/EIA-570, used to implement the community building and the building of the backbone routing, as well as the floor of the residential wiring system. Wiring most star topology, unshielded twisted pair UTP joins.

2. essential communication network.

Intelligent community is the core network. In the ".COM" as the logo of the network society, broadband and intelligent is sure to become a community of equipment, live in the new community of users will soon be experience with broadband channel surf and use the telephone line of the huge difference. Currently, broadband access there are two ways, one is the comprehensive wiring, i.e. community dedicated to this LAN and LAN Internet is directly linked, on the family in the existing cable TV laying of fiber remake, is now a one-way channel cable TV cable into a two-way interactive (HFC). Using both alternative phone Internet access, can achieve online live broadcast TV shows, download, movies, and other "highly difficult moves", however due to a variety of reasons, the cable TV network is not likely to universal access to the InternetSo most of the new community have adopted the integrated distribution system to the laying of complimentary broadband Internet. But the future HFC and cabling, which will develop faster, it is difficult to predict.

Intelligent community of information communication service, should ensure that community residents with networking capabilities and a wide range of access service; this will bring the community to each House of the computers connected with wuyeguanlizhongxin implements new property management by ADSL high-speed Internet access, such as the community residents realize online education, online shopping, IP/TV, multimedia entertainment, online trading, online payment, VOD and Home Office, etc., but also can achieve on the remote control home appliances as well as a cartoon, video intercom, three table automatic meter reading, security/fire monitoring, parking management and other applications.

Since the IP protocol has an open and standard, you can use IP as a key technology of intelligent community. Open the IP to be a ubiquitous Protocol, IP-based Internet has been extended to every corner of the world, which has met the intelligent community population mobility and the needs of diversity. IP application through PSTN, ISDN, wireless networks, satellite networks and cable TV networks, etc. all kinds of transport into the wrong hands.

The popularity of the network will enable community digital information network project a reality. Community digital information network project is based on the global IP network established a financial intelligence information navigation, video on demand, multimedia information service, e-commerce and distance education, and other content as one of the integrated information system network. Users can use the system for fast, accurate and secure way to access and publish information in electronic transactions. On this basis, and gradually developed into a comprehensive information services and electronic commerce Center.

3. the community has intelligent control center, the goal is to ensure that the community of safe and effective management. Major subsystems (see Figure 2) are:

(1) the community and surrounding environment of security monitoring and safety precautions;

(2) family of alert prevention and community response network of alarm;

(3) the community parking lot management system;

(4) family "3" automatic CC transmission;

(5) the smooth flow of communications, protection of audio transmission.

4. community with property management subsystem, a card to complete the various fees.

Community digital information services market in the future will achieve substantial economies of scale. With good market platform to create a multifunctional, easy operation, low-cost integrated community network service system, the advanced Internet technology directly to such a popular and comprehensive service system, not only the mass from the high quality of the information to benefit directly from the network services, while also creating an efficient property of operation system and mode.

Second, the intelligence community's integrated management platform

Community connect various household and office network transmission media including telephone wiring system, cable TV distribution system (fiber-optic TV network), power distribution system and computer network cabling system (CAT 5 twisted-pair), the transmission medium should be the community's basic transmission media.

According to the location of the distribution function, it should be possible, as shown in Figure 3 of centralized management of applications. Park security management in addition to TV monitor system, electronic patrol, parking management and access management can use a safety management system. Household management can use a device to achieve the various objectives of intelligent management and, through the existing network transmission media (telephone, CATV, computer, network cabling, etc.) and central management system of interconnection, in order to reduce the investment and management costs.

3. residential community of intelligent classification standards

Currently, the implementation of the National Ministry of construction is organized in different regions, different types of residential community of intelligent technology demonstration projects. Residential community of intelligent grade will be based on its features and the corresponding investment, Ministry of construction in the national residential community of intelligent technology demonstration project outline "in the intelligent community demonstration project is divided into three levels, on the technical content of the following, as shown in table 1.
