一、前言 随着计算机的发展,故障测试与故障诊断实现自动化已经成为可能。过去靠人工、仪表实现的故障检测,早已由计算机辅助测试(CAT—Computer Aided Test)系统替代。计算机辅助测试系统大都通过计算机和可编程的仪器、仪表组合成较庞大的测试系统,通过软件实现对被测部件或被测系统的测试,提供了比人工测试更为准确、更加迅速的测试 I. INTRODUCTION With the development of computers, the automation of fault testing and fault diagnosis has become possible. In the past by the artificial, instrument fault detection, has long been the computer-aided test (CAT-Computer Aided Test) system to replace. Most computer-aided test systems through computers and programmable instrumentation, instrumentation combined into a larger test system, through the software to be tested on the measured part or the system under test, provides a more accurate and faster test than the manual test
