Study on vibration monitoring system of shipboard antenna based on MEMS

This paper introduces the design of structure vibration monitoring system of shipborne TT&C system antenna based on MEMS sensor,which focuses on the traditional one’s problem that existed design complexity,bulky,high power consumption and so on.The conceptual design of multimode and long-distance structure vibration monitoring system is proposed,and it makes a study on selection of monitoring sensor,software and hardware designing of the vibration monitoring system,then the design flow for the structure vibration monitoring system is presented.According to experimental results,the system can collect vibration signal with range from 0.002g to 20g effectively,which complete real-time acquisition and analysis of vibration signals,and it achieves the expected effect,it provides the theory basis for fault diagnosis and repair of the shipborne TT&C system.
