摘　　要：为解决传统实验室设备资源紧张、更新投入大的问题,将在线仿真计算引入到实验教学中,设计、建立了基于Modelica的虚拟网络实验平台。详细介绍了设计数字电子技术网络实验平台的原理和过程,及相关的结构拓扑组成,并介绍了一种新型的、面向对象的多领域统一建模语言Modelica,利用其对数字电路器件进行了建模及仿真,详述了数字电路译码器元件的建模思路、过程以及实验场景的设计实现中的关键技术,并将模型与前台可视化插件相关联;最后将实验平台与EDA商用软件Multisim进行了比较。研究结果表明了该虚拟实验平台的优越性。In order to solve the problems of traditional laboratory in strained equipment resources and huge invetment for updating, the Internet-based simulation and calculation were applied in experiment education and a network virtual laboratory was designed based on Modelica. The principle and process of designing a digital electronic technique network experiment platform were depicted, also its related structural topology composition was shown. The modeling and simulation of a digital circuit experiment built up with a new-type,object-oriented field unified modeling language called Modelica was introduced. The process of modeling the digital circuit decoder and the key technology of experimental scene design were elaborated, also the models were related to the front desk visualization plugin. The experiment platform was compared with EDA commercial software Multisim. The resuhs show that the advantage of the virtual experiment platform is clear.
