【摘要】 讨论了将第三方子系统集成进具有开放式体系结构的智能楼宇控制系统的一种方法,即通过通用极强的Modbus串行通信协议实现主从系统间的通信。结合将第三方Modbus设备ABB公司的12台PLC集成进霍尼韦尔楼宇监控系统EBI的典型工程,从应用的角度分析了EBI与Modbus设备通讯的原理,给出了组态工程及HMI开发的过程和方法,最终实现了准确的实时监控、实时报警等功能,达到了节源增效的目的。该工程所涉及方法对于基于网络的智能控制系统具有普遍的适用性。更多还原

【Abstract】 A method is presented to integrate the third subsystem be integrated into an open intelligent building control sysytem through the universal Modbus interface. By analyzing a typical project of integration of 12 ABB’s PLCs are integrated into Honeywell EBI system, the principle of the serial communication between the master and the slaves is explained,which shows the ways of project configuration and HMI development. This project has realized accurate realtime supervisal and control , alarming, backuping data, etc. It also achieves saving resources and improving efficiency. The ways this project involved are the same with other distributed intelligent control systems based on networks.更多还原
