基于LabVIEW串行通信系统的开发

Development of Serial Communication Based on LabVIEW

虚拟仪器是由软件实现的,其软件开发平台是LabVIEW。VISA是在所有LabVIEW工作平台上控制VISA、GPIB、RS-232以及其他种类仪器的单接口程序库,通过LabVIEW平台中的VISA模块编写控制程序,可以进行仪器控制。本文以串行通信为例,用LabVIEW构建仪器控制进行串行设备通信,在虚拟环境中使用VISA功能模块向串行设备读写数据,缩短了项目开发周期,提高了开发效率。

virtual instruments are implemented by software whose development is based on LavVIEW. VISA is single interface program library that is used to control VISA, GPIB, RS-232 and other kinds of instruments on LabVIEW work platform. The centrel program that can control instruments is written by VISA module of LabVIEW. This paper illustrates that the instrument is controlled to carry on serial equipment communication by LabVIEW, and VISA module is used to read and write data to serial equipment in virtual environment. It has shortened cycle of item devetoping and improved efficiency of developing.
