关于电子仪器软件化的初步探讨

The Primary Discussion on the Software Emluator of the Electronic Instrument

现代计算机辅助教学有两个方面的重要应用 ,即多媒体教学和远程教育 .其中有关课件缺乏问题是严重的 ,特别是在实验教学方面必须建立相关的虚拟实验 .研究和建立计算机虚拟实验室是一项巨大的系统工程 ,关于电子仪器的软件化和实现虚拟电子实验室是关键 .虚拟电子实验室平台的任务和使用对象都不同于一般的电子CAD和EDA软件 ,两者在仿真要求和数学模型上也有很大的差异 ,因此不能用电子CAD和EDA软件来代替虚拟电子实验 .虚拟电子实验仪器需要一个虚拟实验室平台操作系统来支持 ,该操作平台系统应有较好的交互界面。

Modern computer-assisted teaching has two important applications,multi-media teaching and long-distance educafion.However,the shortage of coursecsare is seriously,especially that of laboratory teaching Therefore,it is necessary to establish related vitual experiment.The research and establishment of virtual computer laboratory is a large systematic engineering,and the key to which is the computerization of electronic instruments and the establishment of virtual electronic laboratory.The task and user of its platform are quite different from the software of CAD and EDA.And both vary greatly in simulation requirement and mathematical model.Therefor,CAD and EDA software can not be used to replace virtual electronic experiment.uirtual electronic experimental instruments need the support of a platform operating system of uirtual laboratory.The operating systm should be of good interactive interface,multimedia quality and expansibility.
