INTELLIGEN HEALTH MONITORING SYSTEM for BRIDGES

A series of bridge collapse take place in recent years, which cause people to pay more attention to bridge health monitoring and early warning. An intelligent health monitoring system for bridges is proposed after analyzing the functions and characteristics of the current bridge health monitoring system. The paper first introduce main functions of system and key technologies, then mainly introduce bridge health monitoring and early warning subsystem based on GIS. The functions of subsystem include bridge spatial data maintenance and management, running bridge health early warning data model to get early warning information, displaying early warning information, querying bridge health data and present the information on electronic maps. To reduce the cost, we select ArcIMS as a means of map issue. We encapsulate the map realization in the module, and it not only separates the service realization and the map realization but also reduces the development difficulty.
