| Abstract: | This paper introduces a kind of new type signal acquisition system that is applied to engine of automobile. It analyses the software and hardware's design and method of realization. Reliability and anti-jamming is solved efficiently by OSR when acquisiting the vibration signal of engine under the circumstance of field work and running. Through the multimode real-time acquisition of vibration signal of engine, it can provide the favorable basic for diagnosing the fault of engine and monitoring the state of engine afterward. |
