In this article we introduced the architecture,database,main functional modules,technical features and functional characteristics of the platform for extracting and processing gravity tidal and non-tidal signals from continuous gravity observation data. The platform meets the needs of large-scale network operation and massive data processing of China's seismic gravity station network. Through calculation of tidal signal processing,non-tidal signal processing and time-frequency conversion in continuous gravity data processing,the automatic cleaning,data quality evaluation and data product production of the massive data of China's seismic gravity station network are realized based on big data technology. Products of 24 kinds data such as gravity tidal factor and time-frequency graph were produced,which improved the application efficiency of continuous gravity observation data and the operation,management and service level of seismic gravity station network.
