N number of basic information index includes: the temperature for the detection information local environment that the cable test side obtains, Electricity locating for the detection information that the humidity for the detection information local environment that the cable test side obtains, the cable test side obtain The indication informations such as the position on cable road, the material of the cable, cable radius, cable insulation thickness；

The numeralization, for will be originally used for numerical value expression finger target value without modification, will not be the finger of numerical value originally Target value is indicated with numerical value, such as cable material can be AVR, AVRB, AVRS etc., then can indicate that AVR, 2 indicate with 1 AVRB, 3 indicate AVRS；

Step S4, there are a defect database in the described background server, there are the appearance of P item in the defect database The detection information data of the cable of defect contain N number of detection information index, N number of detection information index in every data The N number of basic information index extracted in the detection information obtained with the cable test side corresponds, by the P data N number of detection information index constructs defect matrix Q, states matrix Q and contains P row N column, the P row indicates the electricity of defect occur comprising P item The detection information data of cable, N list show the corresponding N number of detection information index of every detection information data, in the defect matrix Q The value of any position indicates the detection information data of the corresponding cable of the row of the position in the corresponding index of the column of the position Value after place's numeralization, while every data also marks corresponding defect information；

Step S5, the vector C and matrix Q is subjected to data normalization processing；

Using step S5, the size of numerical value can be caused to there is very big difference to avoid various indexs because of unit difference It is different, while difference will not occur because of the scale of measurement difference of each index, so that have can for the numerical value for calculating Than property, obtained result is more scientific.

Step S6, the score of every data in the defect database is determined using formula (3)；

Wherein, F_tFor the score of t data in the defect database, C_iFor the basic information vector C's after standardization I-th of value, D_iFor i-th of value of preset index weights vector D, D_iAccording to the significance level of index be set as based on 0 to 1 it Between preset value, Q_t,iFor the value for carrying out the data normalization t row i-th that treated column to defect matrix Q, defect database Value after corresponding i-th of the criterion of t data, i=1,2,3 ... N, t=2,3,4 ... P, calculate all F_t, find F_tIn maximum value, check the defect information of the mark of the data corresponding to the maximum value, defect letter Breath is then current defect information, and the defect information is transferred to the monitoring terminal.

The utility model has the advantages that (1) above-mentioned technology can intelligence the judgement cable whether there is defect.

(2) cable unit length impedance can be obtained according to the detection information that cable test side obtains using above-mentioned technology Value, thus according to cable unit length impedance value to determine whether existing defects.

(3) current data are not only considered when judging whether to occur defect, but are connected according to identical time interval The continuous data for considering n times, to judge the stability of the cable unit length impedance value, and according to judging the cable unit The stability of length impedance value is to determine whether existing defects.

(4) in the judgment process, itself essential information of cable is not only allowed for, it is also contemplated that the factors such as environment, thus So that the result can more match varying environment.

(5) step S5 is utilized, can be to avoid various indexs because of unit difference, and it is very big to cause the size of numerical value to exist Difference, while difference will not occur because of the scale of measurement difference of each index, so that the numerical value for calculating has Comparativity, obtained result are more scientific.

(6) process does not need manual intervention, is fully able to machine intelligence processing, significantly reduces workload.

Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art Mind and range.In this way, if these modifications and changes of the present invention belongs to the range of the claims in the present invention and its equivalent technologies Within, then the present invention is also intended to include these modifications and variations.
