It is very important to do real-time bridge’s health monitoring and have a long time continual analysis and evaluation for the field status of the bridge. In order to make bridges monitoring more sufficient and intelligent, and reduce the cost of monitoring and maintenance of the multiple bridges, it is a new way to implement loosely coupled and distributed monitoring for all the bridges in one city or area. But with the fact that each of the present bridge monitoring subsystems adept different monitoring technology and network architecture, it is difficult to directly connect the existing bridge monitoring systems with their different technical interfaces, and will cost expensive to use some kind of hardware devices to achieve system integration. In this paper, we provide a bridges monitoring system which uses industrial soft middleware to provide different technical interfaces for the integration of the different existing bridge monitoring subsystems and build a unified communication platform over the public communication network. In this way, we lead into loosely coupled and distributed remote monitoring of the multiple bridges in one city or area.
