In the paper,a set of supervising system for rail transit environmental vibration is designed,which integrates vibration signal acquisition,data treating,data uploading and supervision.The supervising node uses DSP digital signal processor to analyze the 1/3 frequency range spectrum and get the index used to appraise the environmental vibration,and upload the processed data to OneNet cloud platform through W5500 communication module.The supervising software is made on account of VS.NET platform.It reads the data stored on OneNet cloud platform through HTTP protocol to monitor the vibration status of rail transit environment.Through detecting the data gathering and the overall performance of the supervising system,the results show that the system is exact in signal gathering,the result is accord with the reality,and achieves the design purpose.
