西华大学课程设计说明书硬币兑换系统摘要:我们在设计此课题中要求设计一个零钱兑换机，用74hc4511、74lvc161、显示管等实现译码、计数、显示等功能。我们选择了一种相对来说较简单的设计方案，进行由上而下层次化的设计，先定义和规定各个模块的结构，再对模块内部进行详细设计。最后将设计好的模块组合调试，并模拟仿真。英文摘要：Wedesigntheprojectsareinthedesignrequirementfora'schangemakers,with74hc4511,74lvc161,XianShiGuandecoding,counting,andgetthedisplayfunction.Wechoosearelativelysimpledesign,bygoupanddownthehierarchicaldesign,firstdefinitionandprovisionsofthestructureofthemodules,andthenamodulewithinthedetaileddesign.Thelastwilldesigngoodmodulescommissioning,andsimulation.英文关键词:transcodecountingreveal关键词:译码计数显示目录TOC\o"1-2"\h\z\uHYPERLINK\l"_Toc266186669"1前言PAGEREF_Toc266186669\h1HYPERLINK\l"_Toc266186670"1.1设计背景PAGEREF_Toc266186670\h1HYPERLINK\l"_Toc266186671"1.2设计概述PAGEREF_Toc266186671\h1HYPERLINK\l"_Toc266186672"2总体方案设计PAGEREF_Toc266186672\h3HYPERLINK\l"_Toc266186673"2.1方案比较PAGEREF_Toc266186673\h3HYPERLINK\l"_Toc266186674"2.2方案论证PAGEREF_Toc266186674\h4HYPERLINK\l"_Toc266186675"2.3方案选择PAGEREF_Toc266186675\h4HYPERLINK\l"_Toc266186676"3单元模块设计PAGEREF_Toc266186676\h5HYPERLINK\l"_Toc266186677"3.1硬币兑换系统组成5HYPERLINK\l"_Toc266186681"3.2电路元器件的选择PAGEREF_Toc266186681\h9HYPERLINK\l"_Toc266186676"４软件简介12HYPERLINK\l"_Toc266186684"5系统调试PAGEREF_Toc266186684\h9HYPERLINK\l"_Toc266186692"5.1系统仿真总图PAGEREF_Toc266186692\h13HYPERLINK\l"_Toc266186692"5.2系统仿真参数设置PAGEREF_Toc266186692\h13HYPERLINK\l"_Toc266186693"5.3功能调试PAGEREF_Toc266186693\h13HYPERLINK\l"_Toc266186694"5.4调结果分析PAGEREF_Toc266186694\h18HYPERLINK\l"_Toc266186695"6系统功能指标参数PAGEREF_Toc266186695\h19HYPERLINK\l"_Toc266186696"6.1系统实现的功能PAGEREF_Toc266186696\h19HYPERLINK\l"_Toc266186697"6.2系统指标参数测试PAGEREF_Toc266186697\h19HYPERLINK\l"_Toc266186698"6.3系统功能及指标参数分析PAGEREF_Toc266186698\h19HYPERLINK\l"_Toc266186699"7结论PAGEREF_Toc266186699\h20HYPERLINK\l"_Toc266186700"8设计总结PAGEREF_Toc266186700\h21HYPERLINK\l"_Toc266186
