Description

technical field

[0001] The invention relates to an automobile overspeed monitoring technology, in particular to a method for monitoring automobile overspeed based on distributed optical fibers. Background technique

[0002] In highway construction, it is difficult to understand the geological conditions of the slope in the preliminary survey work, and the stability of the slope is affected by comprehensive environmental factors, which has the characteristics of dynamic change. It is very large, and there are many geotechnical problems involved, so it is necessary to carry out key monitoring on these parts. Every point can be monitored to avoid the missed detection of serious disasters) monitoring, etc., and achieve good results in the safety monitoring of the slope.

[0003] At present, speeding accounts for a very high proportion of traffic accidents. The commonly used monitoring methods include radar speed measurement, laser speed measurement, and video monitoring. These ...
