Design of the Intelligent Bridge Drainage Monitoring and Control System

When a bridge spans over water, traffic accidents or hazardous chemical spills may result in pollutants entering the waterway through the runoff on the bridge surface, causing water pollution. This study aims to address the shortcomings of existing bridge drainage systems, such as environmental unfriendliness, low efficiency, and difficult maintenance, and to achieve intelligent and informational control of bridge drainage valves. To achieve this, we developed a bridge drainage intelligent control system based on the existing drainage system of the bridge, using Internet of Things (IoT) technology, machine learning technology and information visualization technology. The system consists hardware modules for detecting bridge surface conditions, long-distance wireless communication modules, intelligent drainage valves, and a server monitoring terminal. When a special situation occurs on the bridge surface, the server monitoring terminal will present real-time information on the bridge and send timely instructions to control the intelligent drainage valves to prevent pollutants from being discharged into the water. This study explores a safe, efficient, and environmentally friendly bridge drainage mode, contributing to the construction of a digital-era urban bridge information management system.
