【摘要】 从分析KP1000数字式程度调节仪的功能入手,探讨了串口实时通信的关键技术,在此基础上定义了数据通信格式和实时监 控方法,并给出了一个工业现场智能仪表集中管理监控系统的应用。由于系统在设计和实现中综合了Windows的多线程技术、异步I/ O和基于事件I/O的优势,系统在实时性、可靠性和用户界面上都较以往的系统有较大的提高。更多还原

【Abstract】 On the basis of analyzing the functions of KP1000 digital program regulating controller the critical technology of serial real time communication is investigated. Thus the format of data communication and real time supervisory method are defined and the application of a cenrtalized management and supervisory system is given. Because the advantages of multiple thread of Windows, asynchronous I/O and event-based I/O are integrated in the design and implementation of this system, the system offers enhanced real time capability, reliability and better user interface.更多还原
