远程智能I/O及与DCS系统的互联通讯技术探讨

Technical Probe of the Remote Intelligence I/O and Its Interconnecting Communication With the DCS

在大型电力新建项目和老机组改造中 ,新的技术在不断应用与提高。主控装置通常采用DCS系统 ,参数测点采用国产远程智能I/O设备进行监控 ,并实现与DCS系统的通讯 ,使测点信息传输至DCS系统 ,实现统一的数据管理。文章从远程智能I/O系统的特点及与DCS系统之间通讯的方案等方面进行了阐述 ,为远程I/O系统的应用提供参考。

In the course of the large-scale electric power construction items and the transformation of the obsolete units, the new technology has been improved and applied progressively, in order to communicate with the DCS and realize the unified data management, thus transmit the test information to the DCS,the main control equipment often adopts the DCS, and the parameter test adopts the remote intelligence I/O equipment to monitor which is produced by our country. The paper expounds some scheme through the characteristics of the remote intelligence I/O system and its interconnecting communication with the DCS, and provides some references for the remote intelligenec I/O system.
