Design and Implementation of Data Service Middleware in Earthquake Precursor Instrument Platform

With the gradual development of the earthquake signal early warning system, more and more earthquake precursor signal observation instruments and equipment have been added to the earthquake signal early warning system, which has also caused various compatibility issues. This article designs a data service middleware solution based on B/S architecture for the interaction between earthquake precursor signal observation equipment and remote access terminals on the earthquake precursor instrument platform. Combining embedded technology, it achieves compatible and universal deployment of heterogeneous terminals, and achieves the ideal function of data service middleware. At the same time, in the data service middleware system, real-time data access, presentation, and log upload and download of earthquake precursor instruments are implemented, as well as remote editing of basic information such as instrument IP addresses and station positions, as well as instrument status monitoring and other functions.
