摘　　要：为了满足对在线监测的局部放电信号高速采集的要求,设计并完成了一个基于DSP的多通道数据采集系统,此系统可实现连续高速采样,并可同步采集工频信号得到局放信号的工频相位。详细描述了信号调理、A/D转换、DSP接口、数据缓存以及DSP/BIOSⅡ操作系统、局部放电信号的处理。The paper introduces a multi-channel high speed data acquiring system based on DSP for the partial discharge monitoring. The key feature of this system is that it can realize continuous-time sampling with very high speed, also it can acquire the power frequency phase of PD signal which helps to analyze the PD signal more explicitly. Details are depicted about the DSP interface, A/D converter, data storage, DSP/BIOSⅡ, signal process and so on.
