The Development of Intelligent Shading Technology at Home and Abroad
Since 1984, the United States built the first intelligent building since ten years, in the world, intelligent building with a new look and technology, quickly launched in various places. Especially in Asia, Japan, Singapore, Taiwan and other countries and regions, in order to adapt to the development of intelligent buildings, carried out a lot of research and practice, have built a number of intelligent building. China in the 20th century (the same below) the late 80s to prepare the Ministry of Construction of the "civil building electrical design specifications" JGJ / T16-92, also began to involve the concept of intelligent building, and referred to the building automation and office automation until 90 The concept of intelligent building in the early years was gradually recognized and accepted by more and more people. Especially during the period of 1993-1995, the real estate developers of many large and medium-sized cities in the whole country and their own buildings were designated as "intelligent buildings "," All intelligent building "" 3A-type intelligent building "," 5A-type intelligent building "and so on, a time intelligent building has become a real estate developers to develop sales hot spots.
At the beginning of the year, the Ministry of Construction held the first "Intelligent Building Seminar" in Shanghai Sheshan, and has been in the past five years. During this period, through the understanding of the international intelligent building, through the inspection, engineering design, Academic exchanges, and gradually on the development of intelligent building in a number of issues, the international and domestic intelligent building technology development and trends, from the surface of the phenomenon to its content, with a more in-depth understanding. The design of intelligent buildings, but also to do a more realistic needs.
The current development of intelligent building
The goal of intelligent building is to provide people with a safe and comfortable environment, to provide fast service, the establishment of advanced and scientific integrated management mechanism to achieve environmental protection and energy conservation and reduce labor costs. The intelligent system is designed from the initial subsystems to the system integration, from the building management system (BMS) to the intelligent building management system (IBMS), and is based on the practical and applicable principles of the project, objectively To carry out the design of intelligent system. But also from the side reflects the people's understanding of the meaning of intelligent building, improve the process. From a technical point of view, with the computer technology, network technology, control technology, communication technology and other technology development, for the development of intelligent building has laid a solid foundation. On the other hand the majority of the community developers, project owners, but also from the beginning will be intelligent as a sales hot or greedy requirements, blind pursuit of intelligence, to the present pragmatic attitude, fully embodies the intelligent building is moving The direction of development. Especially for the system integration, in a few years ago, and sometimes become intelligent building intelligent system debate hot spots, as to what is called integration, why integration, how to integrate, from design to academic research, there are many views, many projects , In its integration level is not the same, in 1999 in the United States study, for the integration of some well-known companies to the technical staff on the integration of the exchange of information for the system integration, the main content is building automation ( BA) system-based automation system integration, so that the purpose of environmental protection and energy conservation, to facilitate the management, convenient and quick results. As for the BA system and intelligent building in other systems, you can contact through the Internet to achieve the sharing of information resources. For the BA system-based system integration, in China's "civil building electrical design specifications" JGJ / T16-92 in Chapter 26 has been involved, but with the development of technology, intelligent building in the BA system subsystem The original to be more, but the basic idea is still applicable. In order to facilitate the integration of the system, to achieve a good interconnection between the subsystems, and in the subsystems of the equipment exchange, update and upgrade the convenience of the sub-system equipment to open the requirements, so as to meet the equipment In the integration process will not appear due to different communication protocols, and can not be integrated, but also to avoid the system upgrade, maintenance must appear in the original manufacturers of products, and was asking for high prices in the building automation, Main domestic market or some foreign companies mainly products, such as Joneson, Honeywell, Andover, Landis & Staefa Echelon and other foreign companies.
2 intelligent shade development trend
With regard to the support platform for intelligent building communication networks and office automation systems - integrated wiring, since 1992 the introduction of this technology in the Chinese market, to the domestic intelligent building market to bring a new concept. The emergence of this new technology, immediately in the construction industry caused a huge response. It provides a modular structure for voice communications and data communications. It has excellent openness for voice and data transmission and is used by intelligent buildings. Integrated wiring technology to today, has become an intelligent building in an important system, but also a prerequisite for the design of intelligent buildings. With the development of computer network technology, the bandwidth and speed of network transmission have been developed rapidly, from the original 10M to 100M, to the end of 1999 to 1000M, to the present, there have been higher speed Ethernet. In order to adapt to the development of network transmission bandwidth and speed of development, integrated wiring products are constantly updated, a batch of more excellent performance of new products have come out from the initial 3 lines to 5 lines, in the International Association for Standardization ISO and International Electrotechnical Commission has not yet developed more than five types of integrated wiring system of international standards, many manufacturers have also launched a super 5, 6 cabling system products to meet the needs of Gigabit network, and even some manufacturers to launch 7 categories Even more superior performance of the product, there has been a product ahead of the standard.
Intelligent building is divided into two categories, one is based on public buildings, intelligent buildings, such as office buildings, complex buildings, hotels, restaurants, hospitals, airport terminals, sports venues and so on. The other is the residential-based intelligent residential area. In the whole national economic development, residential construction occupies a considerable proportion of the annual development of intelligent residential area in the hundreds of millions of square meters, has become the construction industry and even the national economy in a new growth point
