摘要
串口通信方式是工业现场仪器或设备常用的通信方式,在对数据传输速率要求不高的应用场合,串口通信是比较廉价的通信方式。主要对LabVIEW的串行通信接口驱动进行了研究,采用虚拟仪器系统标准的API即VISA进行编程,由于VISA本身不具备编程能力,它是一个高层API,所以通过调用底层驱动程序来实现对仪器的编程,完成了基于8051单片机的远程数据采集终端的上位机串口通信接口程序的设计。
Serial communication is the common communication way of industrial instrument or equipment ,and in the application of low data rate demands,serial communication is still a comparatively low-priced communication way. This paper mainly studies the serial communication interface drive in LabVIEW,and uses virtual instrument standard API which is VISA to realize programming. VISA does not have the programming ability,and it is a high-layer API. By calling the bottom drive,the paper accomplishes serial communication interface program of long-range data collection terminal based on 8051 MCU.
