| Abstract: | According to resampling - based order analysis theory, considering the real situation in workshop, by using NI software and hardware, a hardware system is configured for transmission fault diagnosis system and the structure of software is confirmed. It finishes the data acquisition task by NI - 4474 and NI -6601. It can automatically do the data acquisition work according to the control signals. This system achieves and validates synchronous data acquisition of vibration and tachos signals. In addition, it can choose signals according to special RPM range. It has a good effect in working environment. |
