对国内电力SCADA系统常用的远动规约进行了分析和比较,选用国家目前主推的101规约,采用VisualC++2005平台作为开发工具,基于面向对象的设计思想,遵守101规约非平衡方式下的快速-校验-过程规定和连续地成组传输的窗口尺寸为1的原则,设计并开发了远动通信模块,为主站和子站之间的数据通信提供了一种高效通用的技术方法。 This paper analyzes and compares the commonly used telecontrol protocols in domestic power SCADA systems. It selects the 101 protocol which is the main push in the country and adopts Visual C ++ 2005 platform as the development tool. Based on the object-oriented design idea and the 101 protocol’s non-equilibrium mode, - Verification - The process is defined and the principle of continuous group transmission of the window size of 1, the design and development of the remote communication module for the main station and substation data communication between the provides a highly efficient and versatile technical methods.
