摘要
工业控制系统中，计算机控制系统硬件的模块化和软件的结构化、可组态化、开放化是增强其可靠性和灵活性的一项重要工作。“开放性”已成为不可逆转的潮流。ＩｎＴｏｕｃｈ通过动态数据交换（ＤＤＥ）为其“开放性”提供了良好的手段。它可以根据各种控制环境和不同的控制要求，方便地构成相应的计算机监控系统，避免了以往控制系统开发时烦琐的软件编程、调试等低水平上的重复工作；同时，它为操作及维护人员提供了友好的界面，在系统修改、升级方面有良好的灵活性。而且莲花水电站采用ＮｅｔＤＤＥ有效地解决了ＩｎＴｏｕｃｈ与ＵＮＩＸ之间的数据交换。
In industrial control system,it is an important work to reach the modularization of hardware,and structuring,configurability and openness of software in the computer control system in order to increase its reliability and flexibility.The openness has become an irreversible trend.The InTouch software has provided a good way for its openness by using dynamic data exchange(DDE).It could conveniently form the corresponding computer supervisory control system in accordance with various control environment and different control requirements so that it could avoid the previous unnecessary repetition on those overelaborate software programming and debugging.Meanwhile,it also provides friendly interface for operator and maintenance persons and has good flexibility on the system improvement and staging.The NetDDE technology has been adopted in the computer supervisory control system of Lianhua Hydropower Station,which could effectively solve the data exchange between InTouch and Unix.
