计算机仿真技术是当前应用最广泛的使用技术之一，虚拟现实已成为最热门的话题之一。随着科技的发展，计算机仿真技术被广泛运用于众多的领域之中。特别是20年代末，仿真模拟技术在高科技中所处的地位日益提高。在科学研究、工业、交通、军事、教育等领域得到大量应用。计算机仿真技术成为一种工程领域必不可少的重要设计手段，它的应用可以大大地缩短产品的开发周期和降低产品开发的成本，从而提高产品的竞争力。

本文介绍的是LED类部件的设计。主要是普通LED灯和用于显示数字的“8”字灯，为了力图仿真的效果，这里加入了响应时间的因素，以达到接近真实的情况。并分别封装成DLL文件来实现各LED类部件的功能并且易于更新功能。同时，还要求与另一些同学所设计与实现的“大型接口器件的功能演示的可视化设计”，“虚拟实验台的网络化改进方向”，“人机接口设备的仿真实现”等集成在一起，形成一个多功能的接口实验台模拟软件。

本文的最后对设计研究工作进行了总结，指出了研究上的不足，说明了需要进一步深入讨论的内容。

The computer simulation is one of technology employed most widely, and virtual reality has already become one of the hottest topics. With the development of science and technology, computer simulation technology is applied in numerous fields extensively. Especially, in the end of the twenties, the position of simulation technology gets improved in Hi-Tech day by day. It gets a large amount of application in scientific research, industry, traffic, military affairs, educating and etc. Computer simulation technology becomes an essential designing means in engineering field, and its application can shorten the development period of the products and reduce the cost of product development greatly, thus improve the competitiveness of the products.

The thesis introduced the design of LED parts, which is ordinary LED light and " 8 " word light used for displaying figure. For the better simulation result, the factor of response time is taken into accounts, and the LED functions are packaged into DLL file for updating the functions more easily. Meanwhile, it is still required to integrated with other modules to achieve a multifunctional software for interface experiments, such as ‘visualization of functions’ demonstration of large-scale interface device’, ’network oriented improvement of virtual laboratory platform’, ’the emulation of interface apparatus of man and machine’ and etc. which are designed by other students.

At the end of the thesis, it summarized the research work of designing, pointed out the deficiency studied, and explained the content needed further discussing.
