摘　　要：提出以脉冲电源作用下的故障相与健全相的电流差为测量信号,运用小波变换对其作多尺度分解,并利用SoPC技术构建的煤矿井下电缆故障定位片上系统。系统具有具有体积小、成本低、灵敏度高、扩展容易、易于操作等优点,在不同程度上解决了目前煤矿井下电缆故障测定方法存在的问题。In this paper, the coal mine underground cable fault location system-on-chip of using the current difference of fault phase and normal phase under pulse power as a measurement signal, decomposing it on raulti-scale with wavelet transform, using SoPC technology to build,has the advantage of small size, low cost and high sensitivity, easy to expand and easy to operate. Moreover in varying degrees it solves the existing problem of the current determination of coal mine underground cable fault ,and is future research hot spot and trend in this area.
