Embodiment Construction

[0065] A method of predicting the number of times a cable will undergo external force damage failures, such as figure 1 shown, including:

[0066] S10: Obtain at least two sets of municipal engineering raw data in the last two unit time periods, and determine the weight of each group of municipal engineering data according to the municipal engineering raw data to perform fitting to obtain a municipal engineering quantity curve.

[0067] In this implementation manner, the unit time is year, and in other implementation manners, the unit time may be month or quarter.

[0068] The municipal engineering of the set group includes: road length (unit: km), road area (unit: km), length of water supply pipeline (unit is kilometer), green coverage area (unit is hectare), green coverage area-built-up area (unit is hectare), green area (unit is hectare), green area-built-up area (unit is hectare ), park green area (unit is hectare) and park area (unit is hectare).

Abstract

The invention relates to a method for predicting the number of times of cable external force damage failure and a system thereof. The method comprises the steps that municipal engineering original data of the set groups within at least two units of time recently are acquired, and the weight of each group of municipal original engineering data is determined according to the municipal engineering original data to perform fitting so that a municipal engineering quantity curve is obtained; external force damage prevention measure original data of the set groups within at least two units of time recently are acquired, and the weight of each group of the external force damage prevention measures is determined according to the external force damage prevention measure original data to perform fitting so that an external force damage prevention measure curve is obtained; a cable external force damage curve is obtained according to the municipal engineering quantity curve and the external force damage prevention measure curve; and the current failure number of times of cable external force damage failure of current unit time is obtained, and the number of times of cable external force damage failure of the next unit time is predicted according to the current failure number of times and the cable external force damage curve. The number of times of damage failure of the next unit time can be visually predicted by the method.

Description

technical field [0001] The invention relates to the field of power cable fault prediction, in particular to a method and system for predicting the times of external force damage faults in cables. Background technique [0002] The research on cable damage by external force is mainly divided into two parts: the cause of cable damage by external force and the research on how to take measures to prevent external force damage. [0003] (1) Research on the causes of cable damage caused by external force [0004] The research on the causes of cable external force damage can be divided into three categories. The first category is the research on the influence of human factors on cable external force damage faults. The second category is that non-construction personnel have weak awareness of cable protection, especially when construction personnel ignore cable protection during construction; the third category is research on unreasonable construction methods; mainly research on cons...
