High Performance Distributed Data Acquisition System for Long-Term Bridge Health Monitoring

In view of the bridge structure monitor signal type and the distribution characteristic, has designed and constructed a high performance distributed data acquisition system for bridge health monitoring. The system topology uses the double ring network of optical fiber, and has designed the acquisition software flow, analysis department entirely failure diagnosis, the acquisition time synchronization and the system grade of service and realized way and strategy. To the load experiment monitor data analysis, had reflected accurately monitors the section the load stress, has guaranteed system´s reliability and highly effective.
