Abstract: A simple and intuitive method is proposed to describe the circuit diagram as an abstract model of community composed of equipotential points and their relationships. On this basis, this paper mainly discusses a search method of equal potential point on the circuit diagram through the network topology operation of Visio software in the specific environment of electrical engineering teaching simulation. Then, through the model comparison, the consistency of the circuit diagram made by Visio and the standard approach is determined from the functional level.
Key words: Visio; secondary development; electrical engineering teaching simulation; topology; group of equipotential point

Visio作為一款較為流行矢量的繪圖軟件,已經(jīng)被廣泛運(yùn)用于流程圖、工程圖的繪制等領(lǐng)域。它具有繪圖簡(jiǎn)單、靈活和呈現(xiàn)效果好等優(yōu)點(diǎn),這里不再累述。多數(shù)使用者或許沒有注意到,由于該軟件與Word、Excel和PPT等同為Microsoft公司Office系列軟件,它同樣具有強(qiáng)大的后臺(tái)編程控制能力,甚至在這方面其功能明顯強(qiáng)于上述其姊妹軟件,例如其表單(Shapesheet)集成了頁(yè)面上所有圖形(或是圖形組合)的所有可用屬性,通過(guò)在對(duì)應(yīng)的屬性欄填入相應(yīng)的Formula(公式)就能簡(jiǎn)單地改變圖元的形態(tài)、色彩以及位置等屬性。同時(shí),在Visio后臺(tái)的VB編程環(huán)境下,則能夠?qū)崿F(xiàn)對(duì)頁(yè)面中的圖元進(jìn)行較為復(fù)雜的控制,例如時(shí)序控制,也包括本文將要用到的拓?fù)溥\(yùn)算等。不僅如此,通過(guò)其OCX的植入,還能夠在C/C++以及.NET編程環(huán)境下實(shí)現(xiàn)對(duì)Visio繪圖的控制[1]。正是由于Visio軟件不僅有簡(jiǎn)單、靈活的繪圖功能,還具備強(qiáng)大的后臺(tái)編程控制能力,所以Visio軟件可視化仿真方面的運(yùn)用正逐步得到重視。
