論文字數:8195,頁數:25

摘  要
計算機仿真技術是當前應用最廣泛的使用技術之一，虛擬現實已成為最熱門的話題之一。隨著科技的發展，計算機仿真技術被廣泛運用于眾多的領域之中。特別是20年代末，仿真模擬技術在高科技中所處的地位日益提高。在科學研究、工業、交通、軍事、教育等領域得到大量應用。計算機仿真技術成為一種工程領域必不可少的重要設計手段，它的應用可以大大地縮短產品的開發周期和降低產品開發的成本，從而提高產品的競爭力。
本文介紹的是LED類部件的設計。主要是普通LED燈和用于顯示數字的“8”字燈，為了力圖仿真的效果，這里加入了響應時間的因素，以達到接近真實的情況。并分別封裝成DLL文件來實現各LED類部件的功能并且易于更新功能。同時，還要求與另一些同學所設計與實現的“大型接口器件的功能演示的可視化設計”，“虛擬實驗臺的網絡化改進方向”，“人機接口設備的仿真實現”等集成在一起，形成一個多功能的接口實驗臺模擬軟件。
本文的最后對設計研究工作進行了總結，指出了研究上的不足，說明了需要進一步深入討論的內容。

Man-machine Interaction Equipment 
--Simulation Implementation of LED Parts 
Abstract
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.

Key words: Computer emulation; DLL; Update; Integrate
