Cable stake pouring automatic alarm and cable external damage-prevention detection method

Abstract

The invention aims to provide a cable stake pouring automatic alarm and cable external damage-prevention detection method. The vibration response of a stake is monitored in a mode of an acceleration sensor, the modal parameter of the stake is identified by adopting a modal analysis method after the acceleration data is acquired, then, the obtained parameter information is analyzed, the state of the stake is studied, and therefore the external damage situation of the stake is monitored; a vibration monitoring sensor is integrated on a low-power-consumption processor, and a low-power-consumptionNB-IOT communication technology is combined so as to form an effective and high-cost-performance stake monitoring scheme with flexible deployment; the equipment size is small, the service life is long, the deployment is flexible, the implementation can be achieved in steps and in batches, the installation and maintenance difficulty is low, the deployment cost is low, and large-area installation can be realized; and the problem that all existing construction behaviors in an urban area cannot be timely mastered in the existing electric power system construction process, and all construction sites cannot be guarded in a full time period, resulting in that the external damage protection work supervision process of the cable line is quite difficult is solved.

Description

technical field [0001] The invention belongs to a method for supervising electric equipment, and in particular relates to a method for detecting and detecting cable stakes with an automatic alarm for tipping and preventing external breakage of cables. Background technique [0002] In the power system, the 10kV cable line plays a central role in the power supply system. However, due to the large span of the 10kV cable line during the laying process, the relationship with the surrounding environment is very close, making the cable vulnerable to the influence and constraints of external forces. Therefore, it is particularly necessary to take measures to prevent external force damage. In the process of laying and maintenance of 10kv cable lines, the implementation of anti-external force measures can not only play a good preventive effect, but also reduce the damage to a large extent. Safety accidents caused by external force damage. [0003] At present, the external force damag...

Problems solved by technology

[0006] The object of the present invention provides an automatic alarm for cable stake tipping and anti-breakage detection method for cables, which solves the problem that in the construction process of the existing power system, it is impossible to grasp all the construction activities in the urban area in time, and it is also impossible to guard all the construction sites at all times, resulting in the failure of the cable lines. Very difficult problems in the supervision process of anti-breakage protection work
