LabVIEW数据流控制方法研究

本文剖析了LabVIEW 数据流语言的特点，提供了其若干有效控制方法，指出LabVIEW 本身即可解决数据流控制上的变量冲突、响应时序控制、初始状态自适应调整等问题并保证其通用性，而不必求助于其它代码语言（如C 语言），这样，既减轻了程序的复杂性，提高了效率，还丰富了LabVIEW 的应用。文中以单选功能按钮设计实例详述了变量
冲突、响应时序控制、初始状态自适应调整等问题的具体解决方案，在某型装备测试系统的实际运行中验证了该方法可行有效。

Abstract: The character of LabVIEW dataflow programming is analyzed and some methods
on the control of dataflow in LabVIEW are given. Problems such as variable conflict, time
responding sequence control and initial status self-adjustment are able to be settled out without sing other codes (e.g. C language)，so that the programming complexity is less and the efficiency s higher and the application of LabVIEW is more extensive. The example of the design of ingle-activated buttons is detailed showing how to solute the problems above concretely and the xperiment result running on some measurement systems proves the solution is feasible and eliable.
