摘要
针对电路板线或和线与(W-O+W-A)共存的互连故障诊断问题,提出了针对W-O+W-A的GNS算法.该算法采用组同时具备W-O和W-A对角独立性移位序列、网络同时具备W-O和W-A对角独立性移位序列和转移网络同时具备W-O和W-A对角独立性移位序列组成W-O+W-A的GNS序列,重点对其故障诊断能力进行了讨论,并进行了算法的性能验证.
To study the diagnostic problem of W-O ＋ W-A interconnect fault of PCB （Printed Circuit Board）, GNS algorithrns for W-O ＋ W-A is put forward. The algorithm uses group shift sequence with both W-O and W-A diagonal independence, network shift sequence with both W-O and W-A diagonal independence and transferred network shift sequence with both W-O and W-A diagonal independence to form GNS sequence for W-O ＋ W-A. Its fault diagnostic capability is discussed and capability validation is accomplished.
