Underground cable external damage warning spike based on vibration sensor and having wireless communication function

Abstract

The invention discloses an underground cable external damage warning spike based on a vibration sensor and having a wireless communication function, and belongs to the field of detection. A vibration detector, a main controller, a wireless communication module and on-site alarm equipment are arranged in a circular shell; the vibration detector is used for detecting the vibration condition around the position where the spike is located. The main controller is used for storing preset data, periodically detecting data of the vibration detector and carrying out similarity matching on an actual detection numerical value and known model data, when the matching degree reaches 80% and is maintained for preset time, the main controller sends pre-warning information to the background through the wireless communication module, and the background pushes the pre-warning information to a formulated user through a short message. meanwhile, on-site alarm equipment is started to remind on-site constructors to pay attention. The vibration condition around the position where the spikes are located is monitored through the preset spikes on a pavement, a sidewalk or a construction site with burying paths of important pipelines, cables and the like underground, and relevant informing or stopping measures can be taken in advance before an accident occurs, so that the accident is nipped in advance.

Description

technical field [0001] The invention belongs to the detection field, and in particular relates to an alarm device for external damage warning of underground cables. Background technique [0002] With the continuous advancement of the State Grid's "overhead line into the ground" work, more and more underground cables are distributed. [0003] In recent years, among cable faults, external faults account for 80%. [0004] Now the power supply industry generally deploys and sets up warning beacons that can emit light to serve as a reminder. [0005] Because the warning signs are easy to lose (main reason: greening construction, road construction, etc.), and the construction personnel at the excavation site do not observe carefully and other factors, construction often leads to damage to underground cables. The unit to which the cable belongs only knows that a certain cable has been damaged after it has been damaged by external force and caused adverse consequences. [0006] I...
