针对许多机务段由于试验设备不完备，无法全面完成铁道部机车架修工艺要求的空气压缩机试验的情况，我们研制了空压机试验台微机监控及故障诊断系统，完满地解决了这一问题。本文介绍了该系统的功能、特点、软硬件概况，并较详细地介绍了基于单片机的故障诊断方法──故障字典法
For many locomotive depot due to incomplete testing equipment, can not fully complete the Ministry of Railways locomotive repair process requirements of the air compressor test situation, we developed a compressor test bed microcomputer monitoring and fault diagnosis system, a complete solution to this problem. This article introduced this system’s function, the characteristic, the hardware and software general situation, and introduced the fault diagnosis method based on the one-chip computer in detail - fault dictionary method
