The Realization of High-Speed Data Acquisition During the Process of Intelligent Control of Sheet Metal Forming

Real-time monitor is the most important link during the four basic key elements in the intellectualization of sheet metal forming, which adopts effective test means to reflect the mechanics parameter and geometry parameter of the processed target´s characteristic. A high-speed data acquisition system has been established in this paper. It is well realized for high-speed data acquisition using virtual instrument technique based on LabVIEW(Laboratory virtual Instrument Engineering Workbench) as the system controlling software and using the portable computer, 6062E portable data acquisition card, four-slot chassis for signal conditioning, eight-channel module for strain-gauge and eight-channel module for analog output as the hardware. The principle and the design of the high-speed date acquisition system has been introduced in this paper.
