【 Weak current College 】 intelligent building weak electricity technology development prospects

　
Intelligent building weak electricity technology, information technology, is the realization of the intelligent construction features of the main technical means, has a bright future, in the following areas:
1, computer and network technology to the IB's construction play a leading role.
2, network architecture and standards for open protocols, such as BACnet Standard; LonWorks standards, etc.
3, Internet technology (Internet)
With open network transport protocols TCP/IP, and HTTP, uses the client/server architecture. Realize remote monitoring, operations, and comprehensive information for database access.
4. communications technology in intelligent building's direction of development: digital, broadband, high speed, networked, integrated, multimedia communication.
5, the "three-screen integration" is the communication of the party in the field of development.
6, b-ISDN B-ISDN, broadband multimedia communications, IP communications, mobile communications, ATM technologies are rapidly developing applications.
7, extensive application of multimedia technology
8, open the network control technology and BMS development
9, smart card technology and human identification technology
10, Office Automation and extended
11, cabling development prospects
12. system integration is the degree of IB intelligent key flags
13, as soon as possible, improve the intelligent building weak electricity system engineering of strokes, tenders and supervision of standards, improving their management systems and structures, strengthening management technology and team building to accommodate building intelligent engineering healthy and orderly development of demand
The so-called weak electricity is electricity, lighting, relatively speaking. Typically, the power, lighting power known as the strong electricity; the propagating signal, power for the exchange of information is referred to as-current. The strong power of process objects is the energy (electricity), which is characterized by a high voltage, current, power, frequency is low, the main concern is to reduce losses and increase efficiency; weakness of handling objects mainly information, i.e. information transmission and control, its characteristics are low-voltage, current, small, small power, high frequency, the main consideration is information transfer of effects, such as fidelity, speed and breadth and reliability.
First, the automatic fire alarm and automatic fire extinguishing system
The system also known as automatic fire alarm and coordinated control system, or the automatic fire alarm and fire control system, is installed in the field of fire detectors on site monitoring, once the police have alarm fire and linkage corresponding fire-fighting, evacuation, broadcasting equipment, to achieve the purpose of the prevention of fire.
2. communications system
As the information age, the era of knowledge economy, automatic control technology, computer technology and communication technology for development on the buildings information system of the building to pray a great boost, the actual realization of building automation (BA), communication Automation (CA), Office Automation (OA) as well as residential Automation (HA), and independent systems bound to a variety of ways (such as local area network) connection, sharing of accumulated data resources, transfer and processing of data and communication systems and external public network connection, the formation of integrated communication system.
III. cable television and satellite television receiving system
Cable television and satellite television reception of applications and promotion is to address the major urban high-rise buildings or TV signal coverage area beyond remote areas for television signal reflection or appraisal serious and good TV signal reception problems and rich content.
Cable TV system (CableTelevision), abbreviated CATV, by early function antenna television systems (CommunityAntennaTelevision) from the beginning was to share a group receiving antenna systems, and later developed into a closed-form or by wire transfer method for shipping a variety of TV signals, especially the widening to satellite television programmes for reception, microwave relay, video and photography, to organise their programmes, the CATV system synthesis of the information society part of the integrated information network.
Cable TV system also belong to the application of the TV system, and is currently using to monitor control of TV monitoring system form from the transmission of signals to the application scope will vary greatly, so now separate as a weak electricity system.
IV. application of the television system
It is a weak electricity systems engineering an important subsystems. Applied TV are broadcast television systems, in other areas of the application of all the TV system, since the first industrial so traditionally also called industrial TV with the development of science and technology to its applied TV transmission quality is high, the system features strong, wide application, construction convenient, easy operation, safe and does not occupy space frequency, etc., are widely applied in industry, agriculture, scientific research, education, military, etc. Currently applied TV with its unique features and benefits of the extended field of vision, improve productivity, reduce labor intensity, realization of safe production, management, and so has demonstrated a broad development prospects and great value.
5. public address and audio systems
Public address and audio systems there are basically three types: one is the public address (PA), belonging to the cable system, including background music and emergency broadcasting function; second auditorium PA systems; the third is dedicated conference system
VI. safety precaution system
The full name of the security system for public security defense system, is to protect the personal property security, information and communication security, loss prevention and crime prevention purposes.
㈠ burglar alarm system
Burglar alarm system is installed in a protective field range of intrusion detector for the protection of areas of personnel activity detection (invasion), once a intrusion alarm information, will be produced to meet the security objectives.
㈡ TV monitoring system
TV monitoring system is to image monitoring as a means to carry out real-time monitoring of site images and videos. Monitoring system to allow security personnel to visually grasp nowField, and the ability to analyze through video playback. Early television monitoring system is an important part of the TV system, and is also an important part of the security system. Current TV monitoring system has been and burglar alarm system and organically together to form a more reliable control system.
㈢ entrance control system
Access control system also known as the access control system, its function is to control access and control personnel in the prevention of activities in the region. In the prevention area, you must use the class card, password or through biometric technology by controlling device identification confirmation, in order to pass. Car park management system actually belongs to the access control system.
㈣ premises security intercom system
Premises security intercom system for visitors and personnel provide bi-directional communication, or Visual communication, remote control lock and alarm functions.
(V) electronic patrol system
In large buildings or changyuan, entrances, and from the staff of the complex, patrols, the more important locations should be regularly patrol station patrols. Electronic patrol system is security personnel in the provision of patrol routes, at the appointed time and place to the central control room to the signal as normal.
7. building automation system (BA)
Building equipment automation system (BuildingAutomationSystem — BAS) mainly buildings and distribution equipment, emergency backup power supply equipment, reservoirs, non-stop power equipment monitoring, measurement and monitoring of lighting equipment; water supply and drainage systems of water supply and drainage equipment, water and sewage treatment equipment operation, condition monitoring, measurement and control; air conditioning system of heat source equipment, air-conditioning equipment, ventilation equipment and environmental testing equipment operation condition monitoring, measurement and control; thermal system for heat source equipment operation condition monitoring; and elevator, escalator equipment operation condition monitoring. Realization by BAS on building mechanical and electrical equipment of control and management, conservation and human resource management level, with midnight, creating a more comfortable and safe environment.
