What exactly is intelligent?
Beijing is one of the cities that developed intelligence earlier, and developers have also invested heavily in it. Coupled with the media’s publicity, it can be said that as a Beijing citizen We should know a lot about smart homes. What kind of homes can be called smart? Some said it was connected to the home through the Internet, some said it was probably equipped with a security alarm device or an emergency call system, and some people couldn't explain the reason at all and just knew such a term.
The intelligent application system includes four subsystems: property management, public security, home intelligence, and information services. Each subsystem contains many subsystems, and all subsystems are connected into one through the community LAN. overall.
The property management system has 5 sub-systems, covering water supply and drainage, power distribution, area lighting, elevators, heating, electronic maps, three-meter exit, electronic announcements, radio and background music, all-in-one card, Resident service center and community management center, etc.
The public security system has 7 sub-systems, and the home intelligent system includes 2 sub-systems such as automatic control of home appliances.
The intelligent service system is the core of the intelligence of Beichen Green Home. Its content is all-encompassing, from the stock market, securities, foreign exchange, futures to various social news, life knowledge, education, medical care, and games.
The basis for supporting the above information transmission is the integrated cabling system. Considering the future expansion of the system, the backbone network adopts the optical fiber to the building solution. Multi-film optical fiber is used from the central switch to the floor switch, which can be directly upgraded in the future. to Gigabit Ethernet; from the floor switch to the household hub to the household or monitoring and control host using Category 5e twisted pair; from the monitoring and control host central station to the regional sub-station using twisted pair or shielded twisted pair. A video cable is used from the TV surveillance camera to the monitor or video capture card. The access network adopts wireless mode.
What benefits does intelligent housing bring to people?
It creates a safe, comfortable and high-grade living and office environment. In smart homes, doors and windows are equipped with infrared movement, emergency call systems that sense anti-theft alarms, medical first aid, and anti-theft; fire alarms and smoke sensors are gas leakage alarm systems, which make our home life safer and more secure.
To meet users’ needs for different environmental functions, smart houses require that their architectural structure design must have intelligent support. In addition to supporting the realization of 3A (or 5A) functions, it must be an open, long-span frame structure. , allowing users to quickly and easily change the building's use functions or re-plan the building plan. There is also great flexibility in the communications and power supplies necessary for indoor offices. Through the structured integrated wiring system, a variety of standardized weak and strong current socket functions are distributed indoors, such as changing program-controlled telephones into computer communication interfaces.
It has greatly improved people’s communication methods and office conditions. In the information age, time is money. In intelligent buildings, users can obtain global financial business intelligence, scientific and technological intelligence and various database systems in a timely manner through international direct dial telephones, video phones, emails, voice mails, video conferencing, information retrieval and statistical analysis and other means. The latest information in the Internet; through the international computer communication network, you can conduct business and other business activities with enterprises or institutions around the world at any time. Unprecedented high speed is greatly beneficial to corporate decision-making and competition.
It has changed people's traditional way of life and work, and made communication, consultation and social services intelligent through email and computer communication network systems. People can work from home, online shopping, online banking, distance education, e-commerce, etc., which has changed people's traditional way of life and work. Housework is completely automated, and automatic cooking frees people from complicated housework.
One flower brings hundreds of flowers to bloom. The rise of smart buildings can drive the development of various industries in the national economy, open up a huge market for many companies and entrepreneurs, and provide good opportunities for corporate development.
China Nethome Plan
China Nethome Plan, also known as China Nethome Plan, is a cross-century project initiated by Weiji Dali High-tech Development Co., Ltd. .
The plan will be passed C. T. C set-top box and broadband communication technology transmit images, sounds and data to realize a smart home solution of "one network, multiple systems".
Some experts predict that as China officially joins the WTO and foreign high-tech companies enter China, they will promote smart buildings. Real smart homes may not be far away.
What conditions should a smart home meet?
Standards for smart homes: First, there should be sufficient broadband bandwidth to solve the network transmission rate. That is the now popular broadband network.
Smart home includes home smart center system, TV monitoring system, building intercom system, automatic meter reading system, IC card parking lot management system, background music system, community Internet system, and public TV system etc.
The functions of the home smart center system should include paging notification (when the system is in the anti-theft state, if a gangster invades through the door or window, the paging code can be automatically dialed to notify the owner), anti-theft alarm, emergency help, telephone monitoring, telephone Remote control fortification, danger warning (gas leakage, fire alarm), telephone remote control of home appliance switches.
Intelligence does not mean automation. Just installing a number of automated equipment is far from being called intelligence. Home intelligence is not equivalent to the 5A standard for office buildings.
Residence is the place where people live at home. Intelligence should serve people’s home life, so it should be more comprehensive and humane. There are many components of intelligence, but experts believe that a truly intelligent community must have the following qualities: high-speed network access function, that is, Internet network high-speed channel; home office meets the needs of home office; home entertainment includes VOD automatic on-demand , video conferencing, remote teaching, interactive electronic games, etc.; home safety monitoring: such as fire alarms, gas leaks, young children and the elderly seeking help, telemedicine and monitoring, door opening and closing alarms, etc.; home management, such as community electronic bulletin boards, remote three Table transmission charges; home business, such as online shopping, online business contacts, etc.
It can be seen that intelligence is not a single concept, but a very comprehensive system. An important prerequisite for measuring whether a community can be intelligent in the future is whether it has a hardware platform; intelligent integrated wiring of the community The system and central computer room, which are also the most important investments in community intelligence, usually cost several million yuan to realize.
How far is intelligence from us?
The reason why intelligent housing can be used as a selling point for real estate development also shows that intelligence itself has its market demand. However, due to media hype and some exaggerated publicity by developers, Chinese consumers themselves also have misunderstandings about intelligence. First, they believe that the accumulation of simple monitoring facilities and network facilities is the realization of information intelligence. For example, setting up a Video TVs, video doorbells, etc.; secondly, they believe that informatization is difficult and unfathomable. The water heater will turn on as soon as you hit the mobile phone. Some people even hype that refrigerators, microwave ovens, etc. can access the Internet.
Since the beginning of the 21st century, with the changes in modern lifestyles, people's requirements for information technology and network technology have further increased. The development of intelligent residences has relatively come out of the era of hype and has gradually become mature.
Smart houses are coming sooner or later
The rise of computers and network technology and their entry into the construction field have brought a revolution to the way humans live. This revolution has only just begun. start.
According to research by relevant people, office buildings were the first to adopt intelligence. The United States was the pioneer in this field. The concept of intelligent buildings was already available in the late 1970s. In the 1980s, computer networks, information processing and communication technologies Rapid development turned the concept into reality. In 1984, the world's first smart building called "Urban Building" was born in Hartford, Connecticut, USA. After that, it was introduced to developed countries in Europe and the United States. In 1989, the International Convention Center in Makuhari, Matsumoto City, Tokyo, Japan became The world's first high-level smart community. So far, there are smart buildings and smart communities. After 1993, this trend spread to China. Up to now, not only have the intelligence of office buildings made great progress, but even ordinary residential buildings have begun to "fever". Words such as "smart home", "online community" and "not lagging behind in thirty years" are written on it to attract attention. If you want to ask him why you are chasing a star and what is so charming about this star, I am afraid that in the minds of most developers The answer will always be "just follow your feelings".
In fact, it’s no wonder that developers are, after all, the “big names” in foreign intelligence, and they still can’t explain why. Therefore, with the development of the information society in the 21st century, domestic developers are enthusiastic about intelligence. Intelligence will become an indispensable part of the house. By then, I am afraid that it will be like household appliances, nothing rare.
At present, there are generally only three possibilities for domestic netizens to access the Internet: using dial-up telephone through the telecommunications network, using set-top boxes through the cable TV network or telecommunications network, and using broadband IP networks. Each of the three has advantages and disadvantages. Telephone dial-up Internet access is slow, expensive (telephone fee + Internet fee), and cannot have two-way interaction; cable TV optical cables have basically been installed in households, and the speed is fast, but the set-top box technology is not yet mature; China Netcom's broadband IP network will not be launched until the third quarter of next year It has just been officially opened (consumers may wish to ask for more information when encountering smart homes). No matter what method is used to access the Internet, the integrated wiring system is the main platform for smart residential informatization.
The Beijing Science and Technology Convention and Exhibition Center Digital Technology Building uses a structured integrated wiring system. The horizontal area uses Category 5e unshielded twisted pairs, and the vertical system uses 12-core multi-mode optical fiber and Category 3 large logarithm copper. Cable (there are many categories, the higher the category, the higher the rate. It is said that this is the best configuration at present. But there are still big differences in products of different brands), 2 information points are set up every 8 square meters on the standard office floor , (can be flexibly set according to user needs), can be connected to one phone and one computer each, with a maximum transmission rate of up to 622Mbps, which can meet graphics, language and broadband data transmission requirements.
As the leader of the international business community in the Zhongguancun area, the Beijing Science and Technology Convention and Exhibition Center has applied to the Beijing Telecommunications Bureau to locate the communication base station in the Zhongguancun area in the Digital Technology Building (similar in scale to the one built in the Guomao International Trade Center CBD communication base station), it will first meet the needs of the convention and exhibition center, and then expand to other areas of Zhongguancun. According to relevant personnel, the communication base station has all the business functions of the public network and small exchanges, including DID function, operator seat, voice mailbox, call transfer, conference phone, video phone, conference TV, ISPN function, DDN function, etc. , and at the same time, a VSAT (microwave communication) location is reserved on the roof, where small-diameter satellite communication equipment can be installed.
For office buildings, in addition to building automation such as water supply and drainage, power distribution, lighting, etc., temperature regulation is particularly important due to the closed environment of the office building. The Digital Technology Building of the Convention and Exhibition Center adopts a four-pipe fan coil plus fresh air system, which can deliver filtered fresh air to residents all year round in a constant temperature environment (this is not yet necessary for residential buildings).
For fire alarm and security system products, it is generally recognized that American products are superior and are widely used in banking systems. It is said that China Resources Building uses Honeywell products. The Digital Technology Building will use mature products from Japanese companies such as Panasonic.
