A This paper introduces a new type of signal wireless acquisition system with MEMS applied to generator sets. This system bases MEMS accelerometer sensor including high speed multichannel sampling, SD card memory, wireless transceiver module to acquire the vibration signal of engine under the circumstance of field work and running. The system has simple structure, and the sensor can provide high sensitivity. It has very high practical value for diagnosing the fault of generator sets and monitoring the state of engine.
