Design and Application of an Seismic Instrument Data Stream Accessing to Framework

In order to meet the requirements for the comprehensive utilization and exchange sharing of the ancillary data of seismic instruments,we analyzed the way and characteristics of transmitting data flowby seismic data acquisition,and designed a lightweight and reusable application framework by software-engineering ideas and object-oriented software reuse technology methods. This framework could provide a distributed,high-performance and asynchronous pipelined architecture for the design of seismic instrument-oriented data accessing program. We expound the implementation details of the frame in detail and apply the frame on the monitoring system of seismic station running state successfully. The test result showthat the framework is scientific,rational and practical,and our study could provide a typical example for the extension and application of the frame.
