Abstract

In this paper, a real-time multi-channel high-speed data acquisition system for fiber-optic strain array based on DSP was introducted, which the bulk buffer of the system is implemented by combination of CPLD, DSP and SDRAM, and the data transfer is implemented by the combination of DSP, FIFO, USB and USB-HUB. The system could not only work independently in single-channel mode, but also implement high-speed real-time multi-channel mode by combination of multiple single-channels. The largest sampling rate and data storage capacity of each channel could reach up to 100Msps and 256Mbyte respectively. The system mentioned in this paper has such advantages as being flexible to extend, large storage capacity, high precision and real-time process, easy to transfer and etc.
