摘要
为满足现代越来越复杂的电子装备的测试需求,结合测试仪器接口多元化的发展,提出了将VXI、GPIB、1394集成于一体的多总线自动化测试系统。该测试系统采用具有高传输速率的VXI与1394总线,提高了电路板功能测试与故障诊断的效率。系统的通用性避免了测试系统重复性建设而造成的资金浪费,降低了测试成本。并以简单的继电器开关控制电路为例,使用支持向量机分类器对系统测试所得的样本进行故障诊断,诊断的准确率达到了99.73%。
To meet the increasingly complex modern electronic equipment test requirements,diversified with the development of the test instrument interface,put forward a multi-bus auto-test system which integrated VXI、GPIB、1394 in one.The test system used VXI and 1394 these high transmission rate buses,improved the circuit board functional test and fault diagnosis efficiency.Commonality of the system avoided the waste of money caused by the repetitive construction of a test system,reduced the cost of test.And take a simple relay switch control circuit for example,using SVM classifier to classify faults,it can make the accuracy rate of fault diagnosis achieve to 99.73%.
