Design and Implement of SOA-based Bridge Monitoring System Data Layer

General operation of bridge does not have perfect safety monitoring schemes, especially for long span bridge and high-speed railway bridge. Unbalanced bearing force can cause bridge deformation and even serious accidents. In order to provide a comprehensive and intelligent monitoring method, a bridge monitoring system architecture has been presented. This paper analyzes a kind of architecture of monitoring system in order to give a universal approach on bridge health monitoring. Then, it brings a design and implement of system data layer based on spring framework and web service technology by using service-oriented method to solve system heterogeneous issues. This data layer can effectively respond to rapid changes in business and will be maintained and extended easily.
