测试测量设备虚拟维修样机行为建模研究

Research on Behavior-Modeling of Virtual Maintenance Prototyping of Test Equipment

将测试测量设备虚拟维修样机划分为操作部件类和响应部件类,对其行为属性建模方法进行研究。分析了操作部件行为约束关系,基于Vega函数对操作部件的旋转和平移运动方式进行了实现;根据测试测量设备仪表显示特点,将响应部件类划分为数字显示、指示灯亮灭以及波形绘制等基本功能模块;借鉴数码管亮灭控制方法,使用视景仿真建模软件Multigen Creator中的SWITCH节点控制七段数码管的亮灭以显示数字;采用空间绘制曲线的GL-LINE-STRIP算法,基于OpenGL Performer实现了波形的动态显示。

It classes VMPTE＇ s behavior as operation part and response part and makes an research on their behavior modeling method. Analyzed operation part＇ s behavior restriction and realised operation part＇ s rotatation and transition behavior with Vega function. According to the response part＇ s characteristic, it classes response part as number display, indicator light and graph display;It shows numbers with SWITCH node using cgital diode lighting as reference. And then using GL-LINE-STRIP arithmetic realised the real-time graph display on base of OpenGL Performer.
