The vibration monitoring technology for aviation engines includes high-precision, anti-aliasing processing of vibration acceleration and velocity signals, as well as total vibration calculation and vibration spectrum analysis. To adapt to the high-temperature environment of aviation engines, this paper proposes using charge-type vibration sensors for vibration monitoring. High-performance, environmentally resistant ensure processing performance through software and hardware architecture design, meeting different safety design assurance levels and environmental adaptability requirements. By implementing and validating these key technologies in the engine's environment, a solid foundation is laid for subsequent precise engine fault diagnosis and health monitoring.
