【 Weak current College 】 high-tech in the application of intelligent building

United States has recently published the "21st century skills: computers, communication, research report for the 21st century high-tech in the intelligent construction the development and application of that direction. Research report pointed out: "the application will be built on the Internet network on the basis of, and has a good human-computer interaction multidimensional information processing capabilities. Technically, the focus will be on the development of virtual technology, teamwork technology, visualization technology; in the application, the application must be closely integrated, stressed. 　　"Experts say that the following high-tech is a 21st century intelligent building has a wide range of applications and continuing development prospects. Network technology at present, Web-based Internet network technologies is becoming a building or inside the enterprise mainstream information backbone network. With the arrival of the new century, Internet information network will show a strong vitality. 　　Internet/Internet will become a way of life and create a whole new world of information. Control network technology at present, the control network architecture of openness and network interconnection. Open control network with standardized, portability, scalability, and interoperability. 　　In the computer Internet technology, control networks to meet the requirements of openness, it is necessary to walk a path of development of network interconnection and therefore from the scene control bus to control network is an inevitable trend. Smart card technology with the semiconductor chip technology, smart card, small volume, large storage capacity, portable and easy to use, security and reliability, can run offline, the smart card's superior performance and more prominent. Currently, foreign color smart card system for intelligent building security access control and patrol management, parking management, property management fees and management, commercial consumption and e-purse, personnel and attendance management has become increasingly common. 　　While these features through a smart card can achieve the "one card". Visualization technology is based on network video transmission, interaction and providing multimedia video services technology. 　　At this stage, in the intelligent construction of digital video on demand and video conferencing are all color visualization technology to building network desktop system with video transmission, interactivity and service functions. Mobile Office technology is the use of network technology, communication technology, visualization, and home intelligent technology, off-site or mobile office personnel to provide a virtual technology Office environment. Mobile Office technology is more comprehensive modern technology. 　　Mobile Office technology can make at home or traveling Office personnel as in your own Office, you can anytime, anywhere access to the company's business processes, timely processing of files and information immediately; participation in the company held by videoconference, to participate in the presentation and discussion: even through family intelligent technology, remote operation of office equipment in the Office or remote control of appliances in the House. Family of intelligent technologies in the early 1990s, some economies in more developed countries have put forward the "intelligent home" concept. Intelligent technology by family, the family in a variety of information-related communications equipment, home appliances and home security device through family bus technology (HBS) to connect to a family of intelligent systems, centralized or distributed monitoring, control and management of the family, and keep the transactional family facilities and the residential environment of harmony and coordination. 　　A family of intelligent system consisting of high security, living comfort and communication and automation of residential space, you will be able to meet the 21st century information society in the pursuit of fast-paced, external remain completely open living environment. Wireless LAN technology also called computer wireless networking technology that is in the early 1990s, a period of the rise of great practical value of new technologies. The new technology using microwave and laser, infrared as a transport media, free from the bondage of the cable. Color wireless LAN technology can save costly cables, avoiding the cable termination of non-reliability while meeting the computer within a certain range can replace the geographical location of needs, particularly wireless LAN and mobile communications and satellite communications, will play a role. 　　Thus its technology development are being increasingly embraced and attention. Data satellite communications technology at the international level, there is general agreement that data satellite communications technology and PC is 80 's information technology revolution of the main logo. Data satellite also called small data satellite terminals (VSAT), VSAT, the communication terminal extends to the Office and home, its development is the nature of the communications satellite technology to multifunctional, intelligent, device miniaturization, and comprehensive application of the satellite-borne multibeam cover, surface treatment technology, cellular mobile communications and computer software technology. 　　In the 21st century, the development of satellite data will result in a new leap forward. Two-way TV transmission technology can achieve a TV signal from a front-end to the user-end-to-bottom forward sent (downlink transmission), but also can achieve by the client sent back from the bottom up (upstream). Downlink transmission signal mainly TV signal and data information, uplink transmission signal can be a computer terminal data information or control keyboard produces control or status signal, the signal is converted into easy-to-in two-way TV transmission technology signal forms, and through cable modulator, set-top boxes for interaction. 　　Currently, two-way TV transmission technology not only high quality TV programs screen, also named the intelligent building within the traditional CCTV cable television transmission line, to provide interactive data transmission technology for broadband high-speed network for future implementation of the intelligent building of the "triple play" (that is, network, telephone network, computer network) integrated transmission mode provides reserved network interface. Experts predict that, along with the modern high-tech development and widely used, some cutting-edge technologies will also show in the field of intelligent buildings. For example, laser communication technology, robotics, distance education technologies, virtual community technology, telemedicine technology and so on will be in the smart play an important role in the building.
