图书馆可视化节能系统 胡燕南 陈露 陈晓亮 （金陵科技学院 机电工程学院，江苏 南京 211169） 摘 要： 随着现代科技的发展，人类对能源的需求越来越大，有限的能源储存与不断增长的能源需求之间的矛盾日益严重，节能显得日益重要。三菱电机提出的可视化节能理念作为一个新理念正逐渐被推广。本文以图书馆为例，从图书馆存在的主要能耗问题，如照明、空调、计算机用电入手，系统性介绍了图书馆可视化节能系统。本系统在结构上分为数据采集层、数据传输层和实时监控层。数据采集层由远程I/O模块、远程设备站、能量监测模块、特殊功能模块以及分布在各用电设备终端的检测模块等组成，负责采集系统所需的环境参数以及楼层供电主回路的运行参数；数据传输层由采用CC-Link现场总线技术[2]的网络通信模块和主站可编程逻辑控制器PLC组成，进行主站控制命令的发送和执行，实现数据传输以及对底层设备的控制。 关 键 词： PLC；CC-Link现场总线；变频器；电流互感器；A/D转换器；D/A转换器 中图分类号：TP 文献标识码：A Visible Energy Saving System in the Library HU Yan-nan CHEN Lu CHEN Xiao-liang (Mechanical and Electrical Engineering，JINLNG Institute of Technology，Nanjing，211169, China ) Abstract: With the development of modern technology, mankind’s demand for energy is growing; Conflicts between limited energy storage and the growing energy demand are increasingly serious. Energy is becoming increasingly important.. As a new concept, visible energy saving idea proposed by Mitsubishi Electric is being approved. In this paper, we make the library as a example. From the main energy issues, such as lighting, air conditioning, computers electric start, systematically introduces the visible energy saving system in the library. The system is divided into data acquisition, data transport, and real-time monitoring. Data acquisition is made of remote I/O modules, remote device station, energy monitoring module, special function modules, and detection module. It is responsible for collecting environmental parameters required for the system and floor-powered operating parameters of the main circuit. Data transport includes CC-Link Fieldbus technology network communication module and master station programmable logic controller PLC. Its duty is sending and executing control commands from the master, and accomplishing data transmission and controlling the underlying device. Key words: PLC; CC-Link Fieldbus; Converter; current transformer; A/D converter; D/A converter 引 言 作者简介：胡燕南（1993-），女，汉族，江苏如皋人，本科在校生，电气工程及其自动化专业；陈露（1992-），女，汉族，湖
