Intelligent Building integrated Wiring

Intelligent Mansion (Intelligent building) is the product of the development of modern information society, it has become the development direction that the contemporary construction industry and the electronic information industry jointly seek. At present, the governments of all over the world and the transnational enterprise groups have expressed great concern to the intelligent building, and enacted various laws and policies to promote its rapid development. In recent years, the intelligent building has been more and more valued by our government and enterprises, it is understood that many provinces and cities have promulgated the provisions aimed at promoting the development of intelligent buildings. And a large number of property developers, but also for the needs of commercial interests, the development of intelligent building helped.
Integrated wiring system (Integrated Wiring systems) is accompanied by the development of intelligent building, it is the intelligent building to achieve the "highway", in the intelligent building is still immature and perfect today, it even become synonymous with intelligent building, so its development will be faster and quicker. Concept and composition of intelligent buildings and integrated wiring

1. General Concepts
The development history of intelligent building and integrated wiring is relatively short, but it has not formed a unified concept at present. The American Society for Intelligent Architecture (American Intelligent Building Institute) defines an intelligent building as a building that integrates the structure, systems, services, operations and interrelationships to achieve the best combination of efficiency, high performance and high comfort. and the integrated wiring system is to meet the intelligent building of the comprehensive service needs, for transmission of digital, voice, image, graphics and other signals, and support the various types of equipment integrated information transmission system, is an important part of intelligent building. ---http://bianceng.cn (computer science)

2. Composition
Intelligent building mainly by the main control center, integrated wiring system, building automation systems, office automation systems, communications automation system, composed of five major parts:

Main control Center
is the computer as the main body of Intelligent Building Control center, it through the integrated wiring system to connect the subsystems as a whole, the entire building implementation of unified management and monitoring, at the same time for each subsystem to establish a standard information exchange platform.

Integrated wiring System
is the transmission system of all information of the building, the use of twisted-pair or optical fiber cable to complete the transmission of various types of information, different from the traditional building information transmission system is that it uses modular design, unified standard implementation to meet the intelligent building efficiency, reliability, flexibility and other requirements, it generally includes the architectural complex subsystem, equipment between subsystems, vertical subsystems, Horizontal subsystem, management subsystem, work area subsystem, etc. six parts.

Building automation System
The use of modern electronic technology to the building of the environment and equipment operating conditions for monitoring and management, so that the building to achieve safety, comfort, efficiency, convenience and flexibility of the target, specifically by lighting control, air-conditioning control, access control, cold drainage, cooling and cooling source control, power control, fire, security, elevator management, Garage management, such as a number of components.

Office automation system
Office automation System is a computer technology, communication technology, System science and other High-tech support of the auxiliary office automation means, its main include: E-mail, audio-visual, electronic display, property management, word processing, common information base, day-to-day affairs management, and several other parts. It will mainly complete all kinds of electronic data processing, the implementation of various kinds of information effective management and assist decision-makers to make correct and rapid decision function.

Communication Automation System
Responsible for the establishment of the building inside and outside a variety of images, text, voice and data exchange and transmission of information relations. Mainly include: satellite communications, wireless paging, Conference television, visual text, fax, telephone, cable TV, data communication and other parts.
To sum up, the intelligent building in essence it is the use of electronic system integration technology will BA, CA, OA and architectural art organically integrated into a modern information society comprehensive requirements of the building, integrated wiring system is to achieve this combination of organic carrier. Intelligent building's electronic system integration technology and architectural art are both combined and relatively independent (from the professional point of view).

Problems existing in the development of intelligent building and integrated wiring
Intelligent building Electronic System integration part from the professional point of view, its development has evolved into an emerging industry, it needs the industry according to the development of the industry, seriously analyze and study its characteristics, so as to further standardize its development, so that it can be more rapid and better development, In recent years of practical work, I feel that there are several problems to be solved urgently.

1. Design, construction, acceptance need further specification
On the intelligent building and integrated wiring, there are many related industry standards in the world, such as:
eta/tia568; eta/tia570; eta/tia569;iso/iec11801;ieee802.3;ieee802.5, wait.
Domestic also promulgated in 97 "cec89:97 building and complex wiring system construction and acceptance Code", "cec72:97 building and architectural complex cabling system design Code" and other two industry norms.
At present, these standards are mainly integrated wiring system related standards, and is not perfect, for the intelligent Building System integration equipment, interface communication protocol and design and construction has not yet seen more complete and unified standards, so the domestic design and construction units are based on equipment and equipment supplier recommendations for the design and construction, Therefore, the inconsistencies of various intelligent buildings, the quality of the system and performance indicators can not be guaranteed. Although there are not too many problems exposed, it is difficult to ensure that the future needs can be adapted.
Intelligent building is to bear the future "information superhighway" site main node of the task, it is different from the single mechanical and electrical equipment, if the lack of uniform norms, now a large number of building a smart mansion is likely to become the future information in the ocean of the island, so the author believes that the intelligent building and integrated wiring design, construction, Acceptance and other industry norms and standards. To standardize the design team and design standards, standardize the construction team and standards, standardize acceptance agencies and acceptance standards to ensure that the construction of intelligent buildings to adapt to future needs.

2. Access to intelligent building equipment to be strictly
Since intelligent buildings are emerging industries, for system integrators, the selection of equipment and equipment has not a clear basis, at present, many businesses around the world have poured into the domestic, product diversity, which gives system integrators the choice of equipment and equipment to provide a greater degree of freedom, but there is no guarantee that these products are truly in line with the standards, For an emerging industry at the beginning of the development, this situation is a normal phenomenon, but when the industry gradually into mature development period, it is very necessary to have a certain control measures to avoid some non-standard and substandard products charged to the market, the development of intelligent building industry to bring negative impact.

3. The development of intelligent buildings should not blindly
Since the advent of the world's first intelligent building in the 80 's, its development is very rapid, since the 90 's our country also has many intelligent buildings come out, such as: Beijing's Jing Guang Center, Shanghai Sea Trade Center building, Shenzhen King Mansion, and so on, there are many comments that "the true sense of the intelligent building is not yet", but we should recognize that, Intelligent building is a concept of development, it is a system integration, its integrated components can be based on the actual needs, financial situation, technological progress of the development of the development, integrated wiring This realization of electronic system integration and architectural art of the carrier, it is necessary to follow the construction of building and implementation, Therefore, building a comprehensive wiring system at the same time, for the intelligent building of all kinds of system integration equipment to build a good "expressway" platform, the embryonic form of an intelligent building has been established, with the development of the needs of the system integration of the components can be continuously increased and improved.

4. Need to increase the strength of the development of integrated wiring
The integrity of the integrated wiring system will play a very important role in the improvement of the function of intelligent building, and the integrated wiring system is the most intimate part of intelligent building and construction, and the integrated wiring system brings the high long-term investment return to the mansion as the accepted view, However, to enable the majority of owners and construction policy makers to fundamentally understand this point still need to do a greater publicity to promote the work.

5. Development of the domestic system integration industry should be encouraged and protected
At present, access to the domestic intelligent building equipment, equipment almost all foreign products, and even the system integration of the project contract is also the monopoly of foreign enterprises (the actual construction is mostly domestic companies). Such an industry with broad market prospects, such as long-term monopoly by foreign enterprises, the construction industry and electronic systems integration industry will be very unfavorable. For the electronic system integration such a soft technology-oriented industry, the technical level of domestic enterprises is no less than foreign (the development of the foreign system integration industry is also very short), and the domestic system integration industry and the domestic construction industry long-term cooperation experience, so very much need to be able to establish effective measures to encourage and protect the development of domestic systems integration industry, In order to promote the construction industry and the system integration industry to work together, out of a development of China's intelligent building self-reliance road.
