Research on distributed monitoring system of intelligent highway based on weak fiber Bragg grating

The intelligent highway distributed monitoring system employing wFBG sensing technology is promising in the transport engineering. This research proposes a system architecture consisting of weak fiber Bragg grating (wFBG), data link, edge computing region and client interface. The structure and demodulation of the strained optical fiber cable and vibrating optical fiber cable based on wFBG were developed and applied. Further, taking Chen-Bridge and the nearby roadway as the research object, the performance of two types of sensing optical cables was verified according to dynamic and static loading experiments as well as finite element analysis. Moreover, the implementation solutions for intelligent highway functions such as bridge safety status, roadway safety status, lane identification, traffic volume statistics with speed calculation are proposed. Finally, the improvement directions of wFBG applications are analyzed.
