The utility model discloses a bridge health distributed monitoring system based on thing networking, including control management platform, the GPRS communication module who is used for communication and 3G communication module, a plurality of setting at bridge distributed monitoring unit everywhere, the control management platform is passed through 3G communication module and is realized two -way signal connection with remote monitoring terminal and thing networking, the control management platform is passed through GPRS communication module and is realized two -way signal connection with a plurality of setting at bridge distributed monitoring unit everywhere. This bridge health distributed monitoring system based on thing networking conveniently monitors the unsatisfied requirement of health parameter that managers knows large -scale bridge somewhere, conveniently takes corresponding maintenance action, through the cooperation of a plurality of distributed monitoring unit, GPRS communication module and control management platform, its effect that can realize centralized monitoring and unified management, GPRS communication module has solved that communication distance is limited, the low shortcoming of installation cost height and measurement accuracy.
