功能强大的ARM处理器在嵌入式系统以及信号处理与采集系统中得到了越来越广泛的应用。但随着采集速度的不断增加,数据量也成倍的增长,为了保存实时采集到的海量数据,采用USB总线传到PC的硬盘保存。本文将外部的光纤布拉格光栅传感信号通过ARM处理后在LCD上显示波形,同时将得到的数据通过PSIUSBD12保存到硬盘,工作稳定可靠,基本达到了设计要求。
ARM processor is powerful in embedded systems and signal processing and acquisition system has been more and more widely used. However, with the continuous increase in acquisition speed, the amount of data also increased exponentially, in order to save the massive data collected in real time, using the USB bus to the PC’s hard drive to save. In this paper, an external fiber Bragg grating sensing signal is processed by ARM to display the waveform on the LCD, meanwhile the obtained data is saved to the hard disk through the PSIUSBD12, the work is stable and reliable, and basically meets the design requirements.
