图形化编程运行数据在线监测的设计方法

Design Method for Online Monitoring of Graphical Programming Running Data

针对用户无法直接观测图形化编程中可视化组件的实时运行数据,提出了一种图形化编程运行数据在线监测的设计方法。在PC机编译图形化程序时为每一个图形化组件分配虚拟页号和唯一的数据段段号,在平台主机中将图形化组件的数据段段号同实际组件内存相关联,由PC机下发动态监视命令报文,平台主机的背景线程再根据命令报文将组件数据按虚拟页组合并上送,在保证实时地周期执行可视化代码的同时实现了可视化组件多虚拟页同时在线监视功能,提高了图形化程序的开发效率。

In order to solve the unobservability of the runtime data of components in graphical programming,this article proposes a design method for online monitoring of graphical programming runtime data.When compiling graphical programs on a PC,virtual page numbers and unique data segment numbers are assigned to each graphical component.The data segment numbers of graphical components are associated with the actual component memory on the platform host.The PC sends dynamic monitoring command messages,and the background thread of the platform host combines component data and submits them.The proposed method ensures simultaneously real-time periodic execution of visual code and online monitoring of multiple virtual pages in visual components,thus improving the development efficiency of graphical programs.
