In this study, Bridge safety monitoring system using IOT is developed using the Wireless technology.With the help of Advancements in sensor technology have brought the automated real-time bridge health monitoring system. This system will help prevention in disaster management and recovery.IOT-based bridge safety monitoring system is developed using the Wireless Technology. By the use of wireless sensor nodes, various types of data can be collected like vibration, waterlevel and Bridge weight. Thease data would also be useful for monitoring and surveillance. The main moto of this paper is to develop a system that can prevent accidents or structural disasters of flyovers and bridges. This study gives the survey of various techniques used to monitor the conditions of the bridges and proposed a system for monitoring continuous structures and an ultrasonic sensor for monitoring the water level in the river to avoid traffic from a bridge in flood conditions using Kalman’s Filter algorithm. In case of emergency situations the gates of the Bridge will be automatically closed. The obtained data are transmitted to the server and database for admins to have real-time monitoring of the bridge conditions via mobile telecommunication devices.

This paper mainly discusses a method based on Wi-Fi network technology cluster bridge safety monitoring system. In bridge safety monitoring center can be displayed at the same time, analysis of many bridge safety monitoring status, is convenient for decision makers to different budgets, optimize regional bridge within cluster maintenance; through the cluster type bridge safety monitoring, can be realized on the spread over a larger area of bridge security state data comparison, unified management, completely changed the previous single bridge safety monitoring system to realize the information sharing between the" information island" situation, more convenient to the regional environment, similar to different bridge structure or different environment, similar to bridge structure safety status of the longitudinal, transverse analysis comparison and research, which is beneficial to promote the optimum design of bridge structure, and based on the bridge maintenance and reinforcement.

The effective construction of safety monitoring system at construction site depends on perfect management system and advanced technical support. And the lack of information technology platform, resulting in reduced management efficiency, information is not accurate and other issues. Based on the construction site safety monitoring system to achieve the goal, to do a good job in advance prevention, to take the latest information collection technology RFID and BIM integrated comprehensive and effective monitoring of the construction site, constitute the main technology in the monitoring system, thus ensuring the construction site safety monitoring efficiency , Comprehensive, real-time, etc., on the management and technical two points to achieve the construction site safety monitoring, improve the quality of safety management.
