The invention relates to an optical cable
route detection method and device,
electronic equipment and a storage medium, and belongs to the technical field of
optical fiber sensing and sensing networks. According to the method, vibration with specific frequency is emitted, the vibration and irrelevant vibration are distinguished,
scattered light in a to-be-detected optical cable is collected to obtain a vibration
signal, auxiliary signals are superposed in the
scattered light when the
optical power is low, the small
signal processing precision is improved, and scattered signals are obtained according to the
scattered light and processed. Converting the processed scattering
signal to a
frequency domain according to the vibration duration, accumulating
time domain information to improve the
frequency domain signal-to-
noise ratio, improving the routing judgment accuracy, obtaining the peak-to-average ratio of the
frequency domain signal, judging whether the corresponding vibration signal is an effective signal or not, taking the corresponding ground position point as an effective position point, and combining the peak-to-average ratio to judge whether the corresponding vibration signal is the effective signal or not. And obtaining a
route position point right above the to-be-tested optical cable, and obtaining the
route of the to-be-tested optical cable. According to the invention, the accuracy of
vibration detection is improved, so that the accuracy of optical cable routing detection is improved.
