Warning device for preventing underground cables against accidental excavation
A warning device for preventing underground cables against accidental excavation comprises an optical fiber vibration sensor having a mode recognition function, a signal processing unit, a wireless communication unit and a power supply unit, wherein the signal processing unit is connected to the optical fiber vibration sensor, the wireless communication unit and the power supply unit, and the optical fiber vibration sensor is installed within a set range of a cable and is used to monitor vibration signals around the cable, so that once a behavior possibly endangering the cable occurs, an alarm is given out in time to reduce power transmission and transformation accidents. Compared with the prior art, the warning device has the advantages of low false alarm rate, rapid response and accurate localization region.
