针对楼宇自动化实验室中的中央空调设备上位机监控界面功能欠缺、通信不稳定等问题,设计了以直接数字控制器为硬件核心,以LonWorks现场总线为技术平台的中央空调监控系统。介绍和比较了三种基于LonWorks总线的通信方案,得出采用OPC技术的最佳方案,实现了系统的实时通信。
針對樓宇自動化實驗室中的中央空調設備上位機鑑控界麵功能欠缺、通信不穩定等問題,設計瞭以直接數字控製器為硬件覈心,以LonWorks現場總線為技術平檯的中央空調鑑控繫統。介紹和比較瞭三種基于LonWorks總線的通信方案,得齣採用OPC技術的最佳方案,實現瞭繫統的實時通信。

The air-conditioning monitoring system was designed to solve the problem as deficiency of interface function and instability of communication and so on of the air-conditioning equipment in BA laboratory.DDC is used to be the hardware core and LonWorks bus as the technical platform of this system.Three communication schemes based on LonWorks were introduced and compared.And the conclusion was that OPC technology could realize real-time communication.So it's the best scheme.
