Description

technical field [0001] The invention relates to a self-powered bridge damage real-time monitoring device based on an optical fiber sensor, which belongs to the technical field of real-time embedded monitoring and control. Background technique [0002] With the development of society and economy, transportation has become more and more convenient. Bridge construction has played an important role in the development of transportation. However, after the bridge project is built, its health needs to be continuously tested, and its health is directly related to the masses. The safety situation of daily life, in order to repair the bridge in the early stage of damage or fracture, it is necessary to design a device for real-time monitoring of bridge health. The traditional monitoring method is based on wired sensor data collection, which makes it necessary to connect the monitoring center and bridge detection points through cables, requiring the laying of a large number of cables, w...
