With the construction of the National Seismic Intensity Rapid Reporting and Early Warning Project,the monitoring capacity of Chinese Seismic Network has been greatly improved,and the requirements for waveform precise analysis work have also been increased. Traditional products are no longer able to meet the needs of the new stage,and the system should also to be upgraded. In this paper,we introduce the Earthquake Waveform Comprehensive Analysis System,which is one of the subsystems of the National Seismic Intensity Rapid Reporting and Early Warning Project. Through the detailed introduction to the system overview,functional implementation,key technologies,and practical application,we explain how this system can be used to support the new waveform precise analysis work after the completion of the whole project. In the era of rapid development of big data and artificial intelligence technology,the system and its products will encounter the broader development and application field.
