In view of the shortcomings of the monitoring system for State of Bridge depended on the public mobile telecommunication network, which includes the impossibility to carry out the monitoring for a long term or real time, the call for a new method based on IOT has been responded in this paper. This method is concentrated by the cloud computing, modern data communication and industry process data sensor technology. The system is consisted of the forward sensor cells, data collecting & transmitting equipment and Hand-held Terminal. The wireless communication link of modules is established based on ZigBee and Wi-Fi technology. The ZigBee technology is used between sensor cells and data collecting & transmitting equipment, the Wi-Fi technology is practiced to access the upper network by data collecting & transmitting equipment, meanwhile the expert system is responsible for the deep data analysis. Through the long-term monitoring of the basic data such as the deformation of the bridge, this convenient and reliable means provides a scientific decision for the long-term bridge safety maintenance. The proposed solution is of great significance and valuable to theory and practice.
