The data acquisition system uses FPGA as its main controller to achieve the dual-channel acquisition of pulse wave and continuous wave. The ARM9 microprocessor S3C2440 is used as the main processor in this system for data acquiring/processing/storage. Linux OS is ported to the ARM core and Linux device drivers are developed for configuring the FPGA sub system and transmitting data. Compared to optical fiber vibration data acquisition methods (PC+PCI card) before, this method has the advantage of low-power, good expansibility and portability, which makes it a broader usage.
