摘　　要：利用边界扫描技术,对边界扫描器件到悬空插头间的开路故障测试比较困难;通过借鉴国外的研究经验,将边界扫描技术与在线测试技术相结合,用边界扫描器件发送信号,感应电容接收信号的方法,测试电容值大小,来判断节点是否开路,实现开路故障的测试;通过实际模拟验证,得到开路故障节点电容值明显小于正常状态的电容值,判断出了开路的故障节点;因此,证明了方法的可行性,最后对存在的利弊进行了分析总结,期望对国内相关领域的理论研究和实践应用提供有益的参考。Abstract ： It is difficult to test the open fault between boundary scan device and vacant connector in the application of boundary scan tech nique. This thesis combine boundary scan with ICT to solve the＇problem by learning foreign experience. A boundary scan device is used to stimulus a signal and a capacitance is used to receive the response. The fault node capacitance is small than normal value obviously. Then, the open fault node is detected. This method is proved to be feasible by experiments. The advantage and disadvantage is summarized at last. We hope that this method is a good reference to the relevant research and application.
