【摘要】 本课题是设计一种能在无人职守的工业环境中长期稳定工作的新型RTU,作为构成SCADA系统的核心设备,完成遥控、遥测、遥信、摇调功能。作者采用面向对象的设计方法对RTU虚拟机系统进行了总体设计,在此基础上采用模块化设计的方法,把RTU虚拟机系统分解成RTU指令解释和执行模块、实时监控模块、文件传输模块、I/O管理模块以及RTU虚拟机系统的管理模块,分别进行设计和实现。更多还原

【Abstract】 This paper’s goal is to design the new RTU with long-term stability which can work in the industrial environment of no duty, and as the core equpiment of SCADA system, it can achieve the function about remote controling, remote sensing, remote signaling, and remote regulating.The author has given the Object Oriented design method for the general design of RTU Virtual Machine System.The author has applied modular design method to separate it into RTU instruction interpretation and execution, realtime monitor, file transmission, I/O management , management modules and accomplished the design and implementation of these modules.更多还原
