?Intelligent Building Theory of Building Automation System。。。。。。本論文未全部顯示,總約有21435字,查看全文Abstract: This paper describes the building automation system components, functions, and principles of software and hardware technology, history, and related products are briefly introduced the reader of this system has a comprehensive understanding of relevant professional designers for the program designed to provide a theoretical frame of reference. Keywords: building automation system, the core principle of the basic functions of hardware and software technologies1 Introduction to Building Automation System, also known as building automation system (BuildingAutomationSystem referred to as BAS), is an integral part of intelligent building, its task is the building's energy use, environmental, traffic and safety monitoring, control, etc., to provide a safe and reliable, but also save energy, and comfortable work or living environment2.building automation system components and basic functions of building automation systems often include air conditioning, water supply and drainage, power supply, lighting, elevators, fire safety and prevention and other subsystems. According to our industry standards, BAS can be divided into equipment operation management and monitoring subsystem and fire prevention and safety subsystems, as shown. In general, these two subsystems together into BAS consider should, if the fire and safety precautions Ziji Tong independent setting, control center should be established communication with the BAS contact Yipian disaster Fasheng, can achieve the agreed operating Quan Zhuan Yi An Zhao, Jin Xing Yi Tihua coordination and contro.Building automation system's basic functions can be summarized as follows: (1) automatic monitoring and control of various electrical and mechanical equipment, the stop, display or print the current operating state. (2) automatic detection, display, print a variety of electrical and mechanical equipment operating parameters and changes in trends or historical data. (3) According to external conditions, environmental factors, the change automatically adjust the load of equipment, so that is always running in top condition. (4) monitoring and timely processing of all accident emergencies(5) to achieve a variety of electrical and mechanical equipment on building a unified management, coordination and control. (6) Energy management: water, electricity, gas metering and charging, etc., to achieve energy management automation. (7) Equipment Management: including device files, equipment operation and equipment maintenance management reports. 3, the principle of building automation control systemBuilding control system used is based on modern control theory, distributed computer control system, also known as distributed control system (Distributedcontrol systems referred to as DCS). It is characterized by a "centralized management decentralized control," that is charged with distribution of equipment 。省略部分。ure 3, the figure scene controllers, data acquisition station, engineer station, operator station, monitor and manage computer data communication through computer networks are organically combined to form the hierarchical distributed control system3.2.1 A distributed control system data communications network Data communication network is a pillar of the distributed control system. The structure of the distributed control system, which is a network structure, the control station, data acquisition station, engineers, operator stations, monitoring station is the computer on the network "node", contain the CPU and network interface, they all have their own special network address (nodes), can send and receive data through the network, the network of each node in equal status, can share resources and interdependent, form a unified command, and has the function of the dispersed risk, network architecture area is of great flexibility, scalability, can satisfy the distributed control system with the need to upgrade, the expansion is flexible and convenient(1) control network characteristics of distributed control system is different from the general computer network communication network, and general communication network, it is as follows: (1) have special requirements, high reliability and safety requirements of information transmission, therefore absolutely accurate, reliable and often USES redundant technology, backup and diagnosis function. Such as: control station adopt double CPU boards, double I / 0 plate, etc. 2 good performance. 3 strong adaptability to environment. (2) network topology construction equipment automation systems commonly used have bus network and ring network, in two kinds of structure of two nodes can be directly through the network communication, each node in equal status(3) network communication protocol component architecture equipment automation system, there must be a kind of everybody can accept and abide by the working language to realize mutual dialogue, this is the data communication protocol standards. Used for building automation control network BACnet agreement by the physical layer, data link layer and network layer and network components, or the equivalent of open systems interconnection reference model (OSI) first, second, third, seven layer protocol Among them: ARCnet for token bus network, data transfer rate of 2.5-20bit/s, have a good time. MS/TP is a main/transmission from the data link layer technique, allows the use of EIA - 485 hardware. BACnet achieve different manufacturer of automatic control system of communication between technology, i.e., from a "island" to another "island" relationship between the technology5 Conclusions building automation control technology in China is still an emerging technology, with the emergence of more intelligent building, there will be more advanced technology to add to this area, so the technology is more mature and improve參考文獻:…………………………………………………………………………………………
