基于DSP的变电所高频扰动信号采集卡的设计

The Design of High Frequency Interferential Signal In Transformer Substation Acquisition Card Based on DSP

针对采集变电所高频扰动信号的需要,介绍了一种由DSP芯片TMS320VC5509和8位并行高速A/D转换芯片TLC5510组成的高速数据采集卡。经过实测,该卡的数据采集速度可达20 Ms/ps。利用该数据采集卡,可以采集高频扰动信号并存储采集到的数据。

In order to gather the high frequency interferential signal in transformer substation, this article introduce a high speed data acquisition card . DSP named TMS320VC5509 and TLC5510 which is a 8 bits collateral A/D chip compose of the card. According to practical measure, the system＇s acquisition speed can achieve 20 Ms/ps. The card can be used to gather the high frequency interferential signal and save the gathering data.
