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.

摘要： 在岩石变形声发射研究中,为了更好地探究声发射的物理特征,需要不断发展声发射数据的采集和处理技术。地震动力学国家重点实验室的声发射观测系统的记录能力在成倍提升,实验中产生的数据量也大幅增加,这对声发射数据存储、处理和系统地开展岩石变形声发射实验提出了挑战。针对用户的不同需求,文中构建的基于网络的实验室声发射实验数据服务系统不仅实现了数据积累,还实现了数据处理方法的积累和共享。加之与设备无关的声发射数据访问接口的实现,降低了数据访问与处理的门槛,提高了数据的使用率和处理效率。该系统能够满足科研和程序开发用户的需要,能够减少现有工作模式中存在的弊端,可以将其解决方案推广,应用于其它实验数据,提高科研工作效率。
