Deep integration of big data and sensor technology of the Internet of Things, sensing data such as sensing equipment and video monitoring can be used to realize the perception changes of bridge and tunnel structure (collapse, flooding, displacement, vibration, overload, etc.), online warning and structural assessment. A bridge and tunnel supervision and warning system integrating monitoring and warning can be established to realize the digitalization and intellectualization of bridge and tunnel management.

①Data visualization display: bridge and tunnel environment structure characteristics can be displayed in real time, convenient operation and maintenance view。

②Intelligent analysis: real-time collection of information for data analysis, beyond the alarm in time linkage alarm。

③Emergency command and dispatch: Based on various monitoring data, hierarchical early warning response helps decision-making and command。

④Effective technical supervision: equipment management archives, maintenance process traceable, automatic facility fault detection, resource management three-dimensional supervision means。

①Reduce bridge and tunnel accidents

②We will improve our ability to coordinate emergency response

③Improve the speed of response to security incidents

④Realize intelligent supervision
