Abstract
A portable data acquisition and analysis system based on ARM and DSP was developed. The system used master-slave structure: The software of the host computer was developed based on Labview which implemented path, communication, data management and data analysis; the lower computer implemented data acquisition and analysis. The hardware core of the lower computer used “ARM+DSP” dual-core structure; RT-Linux was imported as embedded real-time operation system, which assigned the tasks and enhanced the operational stability and real-time performance of task assignment; The communication between the host computer and the lower computer was achieved by UART module; The Ibutton module was carried out by 1-wire bus technology.
