Design and realization of serial communication interface based on LabVIEW

Serial communication is the common communication way of industry locale instrument or equipment, and in the application of low data rate demands, serial communication is still comparatively low-priced communication way. In this paper the author mainly studies the serial communication interface drive in LabVIEW, and uses virtual instrument standard API which is VISA to practice programming. VISA does not have the programming ability, and it is a high-layer API, realizing the instrument programming by the bottom drive and accomplishing serial communication interface program of long-range data collection terminal super ordination machine based on 8051 monolithic machine, which is used for such following functions: (1) to set up baud rate, data form, verification form and the control of data stream and the document saving route according to different needs, (2) after the program operating, in the nobodys post condition, waiting for receive data from the data collection at any moment, and saving the data under the form to the document being appointed, and waiting for data handling. (3) When uploading data, according to the prescriptive order format, entering the initiation and termination moment in the order window, pressing down sending order, waiting for the data from the monolithic machine data collect system, and saving the data, thereby, to observe the transformation of data.
