Wireless Crack Sensing

This project will develop and deploy a wireless crack sensing system that can measure and monitor cracks in bridge structures. This system will contain the sensing unit, wireless data transmitting system, as well as a data processing unit. The sensing unit(s) will be connected to a wireless transmitting system to broadcast the signal wirelessly. The wireless transmitting system utilizes a blue-tooth technology that can enable the sensing unit to broadcast electronic signals in terms of electrical resistance. These signals will be received by a cell-phone device that can convert the electrical resistance information into the measured strains. The data processing unit will convert the strains into crack displacement and when the measured crack displacement exceeds a predetermined warning threshold, warning messages will be sent to designated terminal devices through a mobile application software. The preliminary installation will be conducted to evaluate the accuracy of the developed system. After initial data collection, the sensing system will be revised and re-deployed in a final field testing.
