Remote automatic real-time bridge monitoring system and method based on MEMS technology

The invention discloses a remote automatic real-time bridge monitoring system and method based on an MEMS technology. The system comprises an MEMS inclination angle sensor, an MEMS accelerometer, a transmission network and a data center, the MEMS inclination angle sensor monitors inclination of bridge members so as to obtain the static flexibility of a bridge under a load effect, the MEMS accelerometer monitors the acceleration so as to obtain a dynamic flexibility function and the natural vibration frequency of the bridge, the MEMS inclination angle sensor and the MEMS accelerometer send monitored bridge data to the data center via the transmission network, and the data center analyzes and processes the bridge data, and evaluates the health condition of the bridge. According to the monitoring system and method, the static flexibility and dynamic flexibility of the bridge floor as well as the gradients of bridge tower, floor and piers can be fit and measured, the health state of the bridge can be evaluated according to power response of the bridge, and important basis is provided for diagnosis on bridge damage and timely maintenance.
