2 1 high-tech in intelligent buildings in the century?

The following is the related content of 2 1 century intelligent building high-tech brought by Zhong Da Consulting for your reference.

The United States recently published the research report "Technology in 2 1 century: Computer, Information and Communication", which pointed out the direction for the application and development of high technology in intelligent buildings in 2 1 century. The research report pointed out: "The application of information technology in the future will be based on the Internet, which has good human-computer interaction ability and multidimensional processing ability. Technically, the focus of development will be virtual technology, collaborative work technology and visualization technology; In application, it is necessary to closely combine the application requirements and emphasize comprehensive integration. " Experts believe that the following high and new technologies will have a wide range of applications and sustainable development prospects in intelligent buildings in the 2 1 century.

network technology

At present, Intranet network technology based on Web is becoming the mainstream form of building or enterprise information backbone network. With the coming of the new century, the intranet information network will show great vitality. Intranet/ Intranet will create a brand-new information world for people's information exchange and lifestyle.

Control network technology

At present, the control network technology is developing in the direction of network interconnection with open architecture. Open control network has the characteristics of standardization, portability, expansibility and operability. Driven by computer internet technology, the control network must follow the development path of network interconnection to meet the requirements of openness, so it is an inevitable trend to move from field control bus to control network.

Smart card technology With the continuous development of semiconductor chip technology, smart cards have become more and more prominent in their superior performance, such as small size, large storage capacity, easy to carry and use, good safety and reliability, off-line operation, and multi-purpose of one card. At present, smart card system is more and more popular in patrol management, parking charge management, property charge and management, business consumption and e-wallet, personnel and attendance management of intelligent buildings abroad. These functions can be realized by smart cards.

Visualization technology

This technology refers to network-based video transmission, interaction and multimedia video service technology. At present, both digital video-on-demand and conference TV in intelligent buildings use visualization technology to provide video transmission, interaction and service for the network desktop system in buildings.

Mobile office technology uses network technology, communication technology, visualization technology and home intelligence technology to provide a virtual office environment for off-site or mobile office workers. Mobile office technology is a synthesis of many modern technologies. The application of mobile office technology can enable office workers at home or on the road to enter the company's office process anytime and anywhere, handle documents and read materials in time, just like in their own offices. Participate in video conferences held by the company, participate in speeches and discussions, and even remotely operate office equipment or remotely control home electrical equipment through home intelligence technology.

Home Intelligent Technology In the early 1990s, some economically developed countries put forward the concept of "intelligent residence" one after another. Through home intelligence technology, all kinds of information-related communication equipment, household appliances and home safety equipment in the family are connected to a home intelligence system through home bus technology HBS, so as to carry out centralized or remote monitoring, control and family affairs management, and keep these home designs in harmony with the living environment. The information-based and automated living space composed of intelligent home system with high security, comfortable life and fast communication will meet the requirements of people in the information society in the 2 1 century to pursue a fast-paced working style and maintain a completely open living environment with the outside world.

Wireless local area network technology, which is a new technology with great practical value, rose in the early 1990s. This new technology uses microwave, laser and infrared as transmission media, and gets rid of the shackles of cables. Using WLAN technology can not only save the expensive cost of laying cables and avoid the unreliability of cable termination, but also meet the needs of computers to change their geographical location at will in a certain range, especially the combination of WLAN with mobile communication and satellite communication will play a greater role. Therefore, people pay more and more attention to the development of its technology.

Data satellite communication technology It is generally believed that the emergence of data satellite communication technology and PC is the main symbol of information technology reform in the 1980s. Data satellite is also called small data satellite station? VSAT, the appearance of VSAT, extends communication terminals to offices and homes. The essence of its development is to lead communication satellite technology to multi-function, intelligence and miniaturization of equipment, and at the same time comprehensively apply multi-beam coverage, on-board processing technology, ground cellular mobile communication and computer software technology. In the 2 1 century, the development of data satellite communication technology will make a new leap.

The TV bidirectional transmission technology can realize the forward transmission and downlink transmission of TV signals from the front end to the user end from top to bottom, and can also realize the reverse transmission of the user end signals from bottom to top? The uplink and downlink signals are mainly TV signals and data information. The uplink signals can be data information of the computer terminal or control or status signals generated by the control keyboard. These signals can be converted into signals that can be easily transmitted on the two-way TV transmission line, and information interaction can be realized through the cable modulator and the set-top box. At present, two-way TV transmission technology can not only transmit high-quality TV program pictures, but also transform the traditional CATV transmission line in intelligent buildings into a broadband high-speed network that can provide interactive information and data transmission, thus realizing "three networks in one" in future intelligent buildings? That is, the integrated transmission mode of TV network, telephone network and computer network, providing reserved network interfaces.

Experts predict that with the development and wide application of modern high technology, some cutting-edge technologies will also show their talents in the field of intelligent buildings. For example, laser communication technology, robot technology, distance education technology, virtual community technology and telemedicine technology will all play an important role in intelligent buildings.
