Design and Software Development of Automated Data Acquisition System for Load Cell Calibration

摘要

The data acquisition system for loadcell calibration has been upgraded from a dedicated instrument controller to a desktop computer with a Microsoft(registered) WIN95 operating system. This paper includes a discussion of the selection of the instrumentation, software, design of the switching network, and software development. The system is controlled and monitored by software developed using National Instruments graphical programming language, LabVIEW. Data reports are generated in Microsoft Excel using Object Linking and Embedding (OLE) routines from LabVIEW. Data are archived in Microsoft Access with OLE routines from LabVIEW. Reports and historical data are electronically available to the test facilities at Arnold Engineering Development Center (AEDC) over the base Intranet.
