基于智能化建筑电气中关键技术的分析

Analysis of Key Technology Based on Intelligent Building

在借鉴国内外新技术成功经验的基础上,系统分析适合我国国情的智能化建筑楼宇中信息采集与处理、PROFI-BUS现场总线技术、智能断路器选用以及组态控制软件与系统布线等几个关键技术的特点,并提出其设计方法和相应的应用准则,目前这些技术在可靠性、方便性以及其市场份额方面较为理想,从而达到遥调、遥测、遥控、遥信的目的。同时又提出PROFIBUS-DP采用数字信号编码中的不归零编码方式(NRZ)的新理念,这为系统组态提供了高度的灵活性。

With improvement of domestic and global intelligent building management, there are many new control techniques,including not only basic functions such as equipment monitoring,operation information feedback, but also information centralizing and sharing. Based on current domestic production and consumption economy, large investment without markets should be avoided. Using successful cases to analyze information collection and process,examine PROFIBUS, select intelligent circuit breakers,investigate applications of control software and wiring system, and propose designed method and application guidelines. Currently, the reliability, convenience, and consumer markets of these remotely regulated, measured, controlled and communicated techniques are adequate. This paper also indicates the concept of PROFIBUS - DP which uses a new form of bi nary code of NRZ （Non Return to Zero） resulting in a more flexible system.
