In order to solve the problem that the service performance of high-speed railway engineering structure declines and affect the safety and comfort of train operation

a vibration monitoring system of engineering structure based on micro-electro-mechanical system（ MEMS） accelerometer

single-chip microcomputer and data cloud storage is proposed.The system mainly includes acceleration signal synchronous acquisition module

vibration signal pick-up and real-time transmission module

server data compression and storage module

The vibration acceleration signal is transmitted to the local industrial computer through wireless access point（ AP）

which can be used for real-time structural safety evaluation in the remote central control room.The experimental results show that when the vibration occurs

the designed monitoring system can accurately collect the acceleration signal in real time and effectively the safety status of the structure.
