Abstract: Acoustic emission (AE) technique is one of the important methods in rock mechanics and experimental seismology. Improving AE data acquiring and processing technology is a basic work in research of the features of AE during the process of rock deformation. Following the progress of the AE systems in State Key Laboratory of Earthquake Dynamics,more and more AE data were obtained with higher recording speed and higher resolution for every experiment. It is a challenge to store such growing data reasonably and deal with it efficiently up to now. Researchers who work in the stand-alone mode have to copy a lot of raw AE data files with different format from remote computer to local PC. Storage space and time are thus squandered away. In addition,every user has to rewrite some processing programs using his own language for the row data,as a result,human resource is wasted. The commercial data service systems are not designed for laboratory study. According to the special demands,AE data service system based on web is designed and realized in the laboratory. Experiment AE data and processing method can be accumulated with the system. On the AE data access interface which is independent of equipments,researchers can acquire and process data easily. The system enhances the frequency of data use and the efficiency of data processing because it allows more and more people to participate in processing and analyzing the AE data. The system not only satisfies the needs of researcher and programmer,but also overcomes the previous shortcoming in the operating mode of AE data management. The most important thing is that the resolvent of AE data service system can be extended and applied to other experiment data to improve work efficiency.
