Abstract
The invention discloses a distributed health-monitoring system for a tunnel structure of a highway bridge, and the system comprises a sensor unit, a front-end information processing node, a star-shaped transmission network, an on-site information processing terminal, and a rear-end information processing platform. The sensor unit comprises a plurality of types of sensors, and obtains the internal information of a tunnel structure of the highway bridge. The front-end information processing node receives the internal information, and makes simple judgment. When the information is abnormal, the front-end information processing node uploads data and keeps silent under other normal conditions. The star-shaped transmission network provides a wireless transmission channel for the front-end abnormal information. The on-site information processing terminal carries out multi-source sensing information fusion, can give an alarm instantly when the health state of the structure is judged to be abnormal, and enables original data to be uploaded through the Internet when judgment cannot be made. The rear-end information processing platform combines a plurality of analysis algorithms and historical data for comprehensive judgment, and gives a final precise monitoring result. The system employs a three-stage distributed data processing configuration, reduces the overall consumption of resources, and improves the alarm efficiency.
