文档介绍：摘要
虚拟仪器是现代计算机技术同仪器技术深层次结合的全新概念仪器,实质是利用计算机显示器的显示功能模拟传统仪器的控制面板,以多种形式表达输出测量结果,利用计算机强大的软件功能实现信号数据的运算、分析和处理,完成各种测试功能的一种计算机仪器系统。
本文介绍了利用LabVIEW语言来实现上、下位机之间通信的方法,并从软、硬件两个方面阐述了设计思想。从实现PC机PC机之间的串口通信出发,先实现双PC机之间的数据发送、返还和接收,进而设计了以PC机作为上位机,以飞思卡尔8位单片机作为下位机的基于labview软件的串口通信系统。经过实验调试,系统达到了预期的通信目标。
应用先进的虚拟仪器软件LABVIEW,大大降低了串口通讯复杂程度,减小了软件设计的工作量,能够大大降低投资成本。在实际应用中有巨大的使用价值。

Design of the munication system Based on LabVIEW
Abstract
Virtual instrument is the puter bined with the instrumentation of the new concept of deep-level instruments, in real terms is the use of puter monitors display control panel, traditional instruments, in various forms to express the output measurements, puter software features to achieve a strong signal Operation data, analysis and processing, plete a variety of testing capabilities of puter instrument system
This article describes the use of LabVIEW to implement the language, the next method munication between the crew and from the software and hardware are two aspects of the design. PC-PC, from the implementation of munication between the departure, the first to achieve double the data between the PC, send and return, receive, and then designed a PC, as the puter to Freescale 8-bit microcontroller based on a lower machine LabVIEW software munication system. After experimental debugging, the system achieved the munication goals.
The application of advanced virtual instrument software LabVIEW, greatly reduces plexity of munication, reduce the workload of the software design can greatly reduce the investment cost. In practice, there is tremendous value in use.
Keywords: virtual instrument; Labview; munication; microcontroller
