Аннотация:Structural health monitoring (SHM) is processes which detects and monitor the destructive part of various structures like bridges, buildings, wind turbines etc. Structural health assessment is widely applied to various forms of infrastructures. Structural health monitoring system elements consider the structural model, various types of sensors, Data acquisition systems, power management unit. SHM system for bridge application is including accelerometer sensor and ultrasonic sensor. Accelerometer sensor is used to measure the tilting angle of bridge pillar and ultrasonic sensor is used to measure the level of water. SHM system developing hardware and software model to be used for distributed real-time monitoring. Two sensor node and central station work at same frequency band. By using the central station, receive sensor data from the nodes and send to the PC. By using the visual basic program uploading data to the static IP address and also developing the android application to send the condition of bridge structure to the people. The wireless sensor network is easy to use; it is require minimum power and its ability to fast data acquisition. The main aim of this project to develop the sensor nodes for bridge health monitoring system and send the bridge situation to the people.
