Fiber bragg grating based bridge safety monitoring structure
The invention relates to the technical field of bridge safety monitoring, and discloses a fiber bragg grating based bridge safety monitoring structure, which comprises piers, a bridge deck and bridgespans, and is characterized in that the piers are used for supporting the bridge deck and the bridge spans; the bridge piers are in butt joint with the bridge spans to form skewback parts, fiber bragggrating strain sensors and fiber bragg grating temperature sensors are arranged at the skewback parts, and first acceleration sensors are arranged on the bridge deck; and the fiber bragg grating stress-strain sensor, the fiber bragg grating temperature sensors and the first acceleration sensors are in signal connection with a server. According to the bridge deck vibration, the first accelerationsensor outputs a voltage signal in direct proportion to the vibration quantity and transmits the voltage signal to the server to monitor the bridge deck; through the fiber bragg grating strain sensorsand the fiber bragg grating temperature sensors, once stress changes occur to the skewback part, the corresponding fiber bragg grating strain sensor transmits signals to the server, remote monitoringis achieved, great convenience is brought to monitoring of a bridge, and the use safety of the bridge is guaranteed.
