The invention discloses a bridge span monitoring system and a monitoring method based on polarized light, and relates to the technical field of bridge span monitoring. The monitoring system includes: a light source, a polarized reflector, a polarized light image acquisition component, and a control center; the light source Used to emit light to the polarized reflective plate; the polarized reflective plate is used to polarize and reflect the light to the polarized light image acquisition component; the polarized light image capture component is used to collect the polarized light reflected by the polarized reflective plate Form a polarization image and transmit it to the control center; the control center is used to obtain a polarization interference fringe spacing according to the polarization images of the bridge under no load and vehicle load, and calculate the distance between the two polarization interference fringes The relative value of the change of the stripe spacing, if the relative value of the change of the stripe spacing is greater than the preset relative value of the variation of the stripe spacing, it is determined that the load of the vehicle exceeds the rated load of the bridge span. The cost of the invention, the cost of maintenance and use are all lower, and it is easy to popularize.
Description
technical field [0001] The invention relates to the technical field of bridge monitoring, in particular to a polarized light-based bridge span monitoring system and monitoring method. Background technique [0002] With the rapid development of my country's traffic construction, the number of bridges in the highway traffic network is increasing. For the safe operation of the highway traffic network, the safety of bridge structures is particularly important. In recent years, the overloaded and over-limited transportation of vehicles has brought great harm to the safety of highway bridges, and has become a major hidden danger in the safety of highway bridges. The illegal overloading of large freight vehicles has caused many bridge toppling and rollover accidents. Bridge monitoring technology can not only carry out the completion acceptance of newly built bridges, but also evaluate the operating bearing capacity of existing bridges, which has become an important technical means...
