针对静态SAMA图不能最大程度地满足虚拟开发的需求,对AutoCAD进行了二次开发,设计了能够让SAMA图与虚拟控制服务器进行实时交互的ARX程序软件,并且利用ActiveX Automation技术实现了 ARX程序的自动加载功能.实验表明,实时SAMA图软件的开发,不仅简化了虚拟DCS系统的调试过程,而且大大缩短了仿真项目的开发时间,有利于虚拟仿真技术的进一步发展.%Due to the static SAMA diagram cannot extremely meet the demand of virtual development, the further development of AutoCAD has been conducted for designing the ARX program software that can implement real-time interaction between SAMA diagram and virtual control server. By adopting ActiveX Automation technology , automatic loading function of ARX program is implemented. The experiments show that the development of real-time SAMA software simplifies the debug procedures of virtual DCS, and also reduces the developing period of simulation project. It is useful to further develop the virtual simulation technology.
