摘要：Labview是虚拟仪器、远程测控等领域的通用编程环境，其基于VISA的编程机理得到广泛应用，VISA支持的接口种类多、功能强大、技术成熟，是目前虚拟仪器及测控编程使用最为广泛的工具之一。串行口是仪表、数据采集、远程测控应用较多的接口，也是最为成熟的接口技术，目前在数据量不大的仪表控制、数据采集、远程测控等领域普遍使用。研究基于VISA的串口通信程序，对于开发串口仪表控制程序、数据采集、远程测控应用具有较通用的参考意义。

Abstract: Labview is the general IDE for Virtual Instrument(VI),its program theory on VISA is widely used,VISA supports many kind of interfaces,has much function and is perfect,it is the popular tool to program the VI and measurement.Serial port is the popular interface of Instrument,DAQ,remote measurement.it is used widely in the no much data area such as Instrument control,DAQ,remote measurement.The research of Serial program baed on VISA has the importance for programming on Instrument control,DAQ and remote measurement.
Key words: VISA; serial port; VI(Virtual Instrument); DAQ(Data Acquisition)
