| 摘 要： | 就柴油机故障诊断而言，采集反映故障的特征信号具有其特殊性．如对喷油系统油压信号的采集，即需要具有高速采集数据的性能，又要能满足特殊同步的要求．该系统是应用了DMA技术的专用数据采集系统，它不仅可应用于舰艇发动机燃油系统的故障诊断，而且还可推广应用于各种柴油机燃油系统的故障诊断。

| Abstract: | As far as the fault diagnosis of diesel engine is conlerned, the requirement of sample signal reiat ed to the diesel engine is special. For example, the characteristics of data acquisition system for sample oil pressure signal of an injection system are of high speed, and special synchronization. This systam is a data acquisition system using the DMA technology. It can be applied to fault diagnosis in the naval vessels en gines fuel system as well as in various diesel engine fuel system. |
