虚拟仪器技术就是利用高性能的模块化硬件，结合高效灵活的软件来完成各种测试、测量和自动化的应用。灵活高效的软件能帮助您创建完全自定义的用户界面，模块化的硬件能方便地提供全方位的系统集成，标准的软硬件平台能满足对同步和定时应用的需求。这也正是NI近30年来始终引领测试测量行业发展趋势的原因所在。只有同时拥有高效的软件、模块化I/O硬件和用于集成的软硬件平台这三大组成部分，才能充分发挥虚拟仪器技术性能高、扩展性强、开发时间少，以及出色的集成这四大优势。LabVIEW（Laboratory Virtual Instrument Engineering Workbench，实验室虚拟仪器集成环境）是一种图形化的编程语言（又称G语言），它是由美国NI公司推出的虚拟仪器开发平台，也是目前应用最广、发展最快、功能最强的图形化软件集成开发环境。使用这种语言编程时，基本上不用写程序代码，取而代之的是程序框图。LabVIEW的特点如下：

? 编程简单； ? 开发周期短； ? 高效性； ? 开放性； ? 自定义性；

? 性价比高，能一机多用。

2.1 时钟显示的结构

本课题要求设计一个数字时钟。通过获取电脑的系统时间，并分离出给数字，在通过布尔显示显示。数字的显示主要是7个长条的布尔显示组成，原理与7段数码管相似。7段数码管显示不同的数字主要通过其7个布尔不同的真假值控制，将0-9对应的7段布尔显示值依次存入一个布尔数组里，只需提取此数组的不同段即可让其显示不同的值，如显示“0”提取数组的0-6位分别赋值给7段布尔显示。

2.2设计总思路

获取时间的控件可以获取的信息有：年、月、日、星期、天数、时、分、秒、秒小数等，取得的值为整型数据，利用除数取余即可分离个十位。为了获得更好的显示效果将背景改为黑色，布尔显示的颜色为绿色。

3.1获取时间的各整型数据

软件中获取日期/时间（秒）控件从计算机系统中自动提取时间，并转换成日期、时间等，控件图如下：

图3-1

在获取时间后，将数据解除捆绑即分别取得年、月、日、时间等，如下图：

图 3-2

3.2提取数字的各位

通过除10取余便可得到个位，商为十位，以此方法也可求出年的各个数字，如下图：
