摘　　要：利用混沌脉冲位置调制信号(CPPM)结合分布式时域传输测量法能够实现电缆网络故障的及时检测和准确定位。实验通过对构建的Double-Y型电缆网络中支路位置的故障进行探测,从而证明该方法的可行性。结果表明:该方法能够准确、高效地对电缆网络故障点进行定位和识别。Present a transmission measurement method to determine faults position in a multi-branch network using a distributed diagnosis strategy.The idea is based on the use of wide-band quasi-orthogonal chaotic pulse position modulation（CPPM） signals for distributed diagnosis.The experiment was test on a double-Y branched network and shows excellent potential of chaotic signals used for distributed faults location of complex topology networks.The experimental results show that the proposed method can effectively solve ambiguities due to the existence of multiple paths.
