本文主要介绍了SCADA系统在中央空调系统制冷机房中的应用。随着人们办公、生活品质的提高,对中央空调系统制冷机房供冷要求也相应提高,同时国家和企业、个人节能减排的意识增强,企业为了降低运营成本,等等这些都使得智能化、科学化的管理和运行中央空调系统制冷机房设备成为了当务之急。在此,笔者通过对系统硬件设计方法和软件设计思路的介绍,从设计及应用角度介绍了一套由现场测量监视设备及现场执行设备、PLC、上位机等组成的实用控制方案。该SCADA系统采用了Sunwayland组态软件(包含Webserver,语音电话报警),Siemenss7-300PLC控制技术,变频调速控制技术,使整个中央空调系统制冷机房中的设备实现可靠智能自动节能运行。
This article mainly introduces the application of SCADA system in the central air conditioning system refrigerating machine room. With the improvement of people’s office and living quality, the cooling requirements for the central air-conditioning system refrigerating machine room have also been correspondingly improved. At the same time, the awareness of energy saving and emission reduction has been strengthened in the countries, enterprises, and individuals. In order to reduce the operating costs, the enterprises have made them intelligent, Scientific management and operation of the central air-conditioning system cooling equipment room has become a top priority. Here, the author introduced a system hardware design method and software design ideas, from the perspective of design and application of a set of field measurement monitoring equipment and field execution equipment, PLC, upper computer and other practical control program. The SCADA system uses Sunwayland configuration software (including Webserver, voice phone alarm), Siemenss7-300PLC control technology, frequency conversion speed control technology, so that the entire central air conditioning system in the refrigerator room equipment to achieve reliable and intelligent automatic energy-saving operation.
