The intermittent fault is a main factor that temporarily disables mechatronics system and incurs the BIT false alarms. Diagnosing intermittent faults is an efficient approach to improve performance and to reduce false alarms of the BIT.
国内外装备实践表明:间歇故障是导致机电系统BIT虚警的一个主要原因,诊断间歇故障能有效地提高机电系统BIT的性能和降低虚警。

该方法通过少量样本训练出有效的模型,实现对间歇故障的诊断。
Then the SVM based intermittent faults diagnostic method is presented. With the features extracted from small samples, the SVM models are trained to diagnose intermittent faults.
与传统两状态方法相比,基于三状态方法的BIT通过诊断间歇故障,不仅有效地抑制间歇故障引起的虚警,而且还能提高故障检测率。
By diagnosing intermittent fault, BIT with the method is better than that of two-state method in reducing false alarm rate as well as increasing fault detection rate.
这些较复杂的场景趋于暴露出较困难的故障,它们更难调试,并且有时是间歇的。
These more complicated scenarios tended to expose more difficult bugs, which were harder to debug and sometimes were intermittent.
