The parameter analysis model comprises a coefficient analysis formula and a combined coefficient calculation formula. Through calculation of the two formulas, parameter analysis can be carried out on the basic parameters of the cable, so that corresponding attenuation coefficient information is obtained. The cable impedance value and the cable basic parameter can be calculated according to the coefficient analysis formula, so that the characteristic impedance attenuation coefficient and the crosstalk attenuation coefficient can be respectively obtained. Specifically, a coefficient analysis formula for parameter analysis of a certain wire core can be represented by using formula (1):

Further, the characteristic impedance attenuation coefficient and the crosstalk attenuation coefficient may be calculated according to a combination coefficient calculation formula, so as to obtain a combination attenuation coefficient, and specifically, the combination coefficient calculation formula may be represented by using formula (2):

Wherein Sz is the calculated combined attenuation coefficient.

And combining the obtained characteristic impedance attenuation coefficient, the crosstalk attenuation coefficient and the combined attenuation coefficient to obtain attenuation coefficient information.

And acquiring detection configuration information matched with the attenuation coefficient information and the initial detection parameters from a preset detection configuration table. Further, detection configuration information matching the attenuation coefficient information and the detection conditions may be obtained from a detection configuration table, that is, a configuration table for performing detection parameter configuration. The matched detection configuration information can be obtained according to the attenuation coefficient information and the initial detection parameters of each strand of wire core, wherein the detection configuration information comprises signal transmission power corresponding to each wire core respectively, and the signal transmission power is the electric signal power corresponding to the detection of each group of wire cores.

In one embodiment, step S140 includes the steps of: determining a corresponding coefficient fluctuation range according to attenuation coefficient information of each strand core; combining the coefficient fluctuation range with the detection condition to obtain a combined screening characteristic; screening the configuration information in the detection configuration table according to the combination screening characteristics to obtain configuration information matched with the combination screening characteristics; and correspondingly calculating the detection configuration information according to the basic parameter information of each strand core in the initial detection parameters and the configuration information.

Specifically, the corresponding coefficient fluctuation range can be determined according to the attenuation coefficient information of each strand core, specifically, the minimum value and the maximum value of each coefficient value can be respectively determined from the characteristic impedance attenuation coefficient, the crosstalk attenuation coefficient and the combined attenuation coefficient of each strand core, so that the fluctuation range of each coefficient value is determined, and the corresponding coefficient fluctuation range is obtained. And combining the coefficient fluctuation range with the test wave frequency in the detection condition to obtain combined screening characteristics, wherein the configuration information in the detection configuration table comprises characteristic values corresponding to the characteristics, and the characteristic values of the configuration information in the detection configuration table can be screened according to the combined screening characteristics, so that the configuration information with the characteristic values all positioned in the combined screening characteristics is obtained as the configuration information matched with the combined screening characteristics. Wherein each configuration information includes a power calculation coefficient.

And calculating according to the basic parameter information of each strand core in the initial detection parameters and the power calculation coefficient in the configuration information, so as to obtain the signal transmitting power corresponding to each strand core. For example, the calculation formula for calculating the signal transmission power of the wire core may be expressed by the formula (3):

Px＝s _x ×p ₀ (3)；

Wherein P is ₀ For calculating the coefficient of power in the configuration information matched with the combination screening characteristics, px is the signal transmitting power of a certain strand of wire core obtained by calculation, s _x Is the cross-sectional area of the wire core.

And sending detection signals corresponding to the detection configuration information to the detection ports of the strand cores according to the port mapping information so as to obtain initial detection information corresponding to the strand cores. Because the port mapping information contains the corresponding relation between each strand core and the detection interface, the intelligent detection terminal can send detection signals to the detection ports of each strand core according to the detection conditions and the detection configuration information in the initial detection parameters. The detection signals sent to the strand cores can be sent simultaneously, and then the initial detection information of each strand of information can be obtained by detecting each strand core through sending the detection signals. The obtained initial detection information comprises initial signal intensity and signal drift ranges which respectively correspond to all frequency values in the frequency of the test electric wave; the initial signal strength is the strength value of the signal received by the receiving end of each strand core, and the unit is mW (milliwatt). An electric signal with rated frequency is transmitted from one end of the wire core, a corresponding receiving signal can be received from the other end of the wire core, the electric signal received by the receiving signal possibly contains clutter signals, the clutter signals are electric signals which do not correspond to the transmitted limit frequency, namely, the wave shape distortion of part of wave signals is caused by reflection and refraction in the signal propagation process of the receiving signal, namely, the wave signals are subjected to frequency drift. For example, if the rated frequency of a certain transmitted electric signal is 2.2MHz, the main signal of the received signal is a wave signal corresponding to the rated frequency of 2.2MHz, the lowest frequency of the received spurious signal is 2.183MHz, and the highest frequency is 2.216MHz, the signal drift range of the currently received signal is 2.216-2.183=0.033 MHz.

For example, if the test electric wave frequency in the detection condition is 2MHz-20MHz, the signal voltage is 12V, and the signal transmission rate is 5Mbp, according to the signal voltage, the signal transmission rate, and the signal transmission power corresponding to the wire core in the detection configuration information, a corresponding detection signal is transmitted to the detection port corresponding to the current wire core, where the transmission frequency of the detection signal corresponds to the test electric wave frequency.

And S160, respectively carrying out distortion adjustment on initial detection information corresponding to each strand core according to the attenuation coefficient information, so as to obtain adjusted detection information.

And respectively carrying out distortion adjustment on initial detection information corresponding to each strand core according to the attenuation coefficient information, thereby obtaining adjusted detection information. Specifically, since the transmitted detection signal is in a frequency range corresponding to the frequency of the test electric wave, rather than a fixed frequency value, the attenuation coefficient information of each strand core is changed at different frequencies, so that the obtained initial detection information of each strand core is distorted due to the difference of the attenuation coefficient information, and in order to obtain a more accurate detection result, the initial detection information corresponding to each strand core can be respectively distorted and adjusted according to the attenuation coefficient information, so that the detection information corresponding to each strand core after adjustment is obtained.

In one embodiment, step S160 includes the steps of: calculating basic attenuation information corresponding to the basic parameters of the cable; calculating to obtain distortion coefficients corresponding to the strand cores according to the attenuation coefficient information of the strand cores and the basic attenuation information; and carrying out distortion adjustment on initial detection information corresponding to each strand core according to the distortion coefficient to obtain adjustment detection information.

Specifically, the basic attenuation information corresponding to the basic parameters of the cable can be calculated, the combined attenuation coefficient of each cable is calculated according to the intermediate frequency value of the frequency of the test circuit, and the combined attenuation coefficients corresponding to the intermediate frequency value of each cable are respectively calculated in an average mode, so that the corresponding basic attenuation information is obtained. The calculation formula of the basic attenuation information can be expressed by adopting a formula (4):

wherein G is the number of wire core strands, S _zn Is the combined attenuation coefficient corresponding to the intermediate frequency value of the nth strand core, S _j Is the coefficient value of the base attenuation information.

And calculating to obtain a distortion coefficient corresponding to each strand core according to the attenuation coefficient information and the basic attenuation information of each strand core, and carrying out distortion adjustment on initial detection information corresponding to each strand core according to the distortion coefficient to obtain adjusted detection information, wherein the numerical correction is carried out on the detection value in the initial detection information.

Specifically, the process of calculating the distortion coefficient can be represented by the following formula (5):

wherein J is _i Is the corresponding distortion coefficient when the frequency value is i, szi is the combined attenuation coefficient of a certain wire core when the frequency value is i, S _j The rate of change of the frequency value i is 0.001MHz as the coefficient value of the basic attenuation information.

And according to the calculated distortion coefficients of the wire core and the frequency values, performing distortion adjustment on the values in the initial detection information of the wire core, namely multiplying the distortion coefficients by the signal strength of the corresponding frequency values in the initial detection information. For example, the original signal strength corresponding to the frequency value of the initial detection information of a certain wire core being 2.500MHz is P ₁ A distortion coefficient J with a frequency value of 2.500MHz ₁ After distortion adjustment, the new signal strength corresponding to the frequency value of the initial detection information of the wire core of 2.500MHz is P ₁ ×J ₁ . And then, after the signal intensity in the initial detection information of a certain wire core is subjected to distortion adjustment according to the distortion coefficient corresponding to each frequency value, adjusted detection information can be obtained, and each wire core is detected based on the adjusted detection information, so that a more accurate detection result can be obtained. By the method, the initial detection information of each wire core can be respectively subjected to distortion adjustment, and adjustment detection information corresponding to each wire core is obtained.

And S170, verifying whether the adjustment detection information of each strand core is matched with the standard detection information so as to obtain a detection result of whether each strand core in the cable to be detected is qualified.

And verifying whether the adjustment detection information of each strand core is matched with the standard detection information or not so as to obtain a detection result of whether each strand core in the cable to be detected is qualified or not. In order to realize whether each strand core is qualified or not, whether the adjustment detection information of each strand core is matched with the standard detection information or not can be verified, so that detection of each strand core is realized, and a detection result containing the detection information of each strand core is obtained, namely, the communication quality of each wire core in the cable can be combined and embodied through the detection result, and the combination detection of each strand core in the cable is realized. The standard detection information is information for verifying whether the adjustment detection information of each strand core accords with the corresponding standard, and whether each strand core is qualified or not can be verified through the standard detection information.

In one embodiment, step S170 includes the steps of: acquiring signal intensity and signal drift range corresponding to each frequency value in the adjustment detection information of each strand of wire core, and drawing a wire core detection curve based on three-dimensional characteristics; the wire core detection curve takes a frequency value as a horizontal axis, signal intensity as a vertical axis and a signal drift range as curve width; and judging whether each wire core detection curve accords with each detection item in the detection standard information according to the standard detection information, thereby obtaining whether the adjustment detection information is matched with the standard detection information.

Specifically, the signal intensity and the signal drift range corresponding to each frequency value in the adjustment detection information of each strand of wire core can be firstly obtained, the frequency value is taken as a horizontal axis, the signal intensity corresponding to the frequency value in the adjustment detection information is taken as a vertical axis, the signal drift range is taken as a curve width, a wire core detection curve based on three-dimensional characteristics is drawn, and each strand of wire core can obtain a corresponding wire core detection curve. That is, each wire core detection curve contains data values corresponding to three dimensions of a frequency value, a signal strength and a signal drift range, so that the acquired signal characteristic information of the adjustment detection information can be comprehensively reflected through the wire core detection curve.

The standard detection information comprises a plurality of detection items, whether the wire core detection curves meet the detection items corresponding to the detection standard information can be judged, and if the wire core detection curve of a certain wire core meets the detection items in the detection standard information, the adjustment detection information of the wire core can be confirmed to be matched with the standard detection information; if the wire core detection curve of a certain wire core does not accord with any detection item in the detection standard information, the adjustment detection information of the wire core can be determined to not match with the standard detection information.

In an embodiment, the determining, according to the standard detection information, whether each wire core detection curve meets each detection item in the detection standard information, so as to obtain whether the adjustment detection information matches with the standard detection information includes: acquiring standard detection ranges corresponding to the detection conditions and core parameters of each strand core from the detection standard information; judging whether curve parameters of each wire core detection curve are matched with range values of each detection item in the corresponding standard detection range or not so as to judge whether each wire core detection curve accords with each detection item in the detection standard information or not.

The detection standard information comprises detection ranges corresponding to various detection conditions and various wire core types, the detection conditions in the initial detection parameters and the wire core parameters of each wire core can be matched with the matching conditions of each group of detection ranges in the detection standard information, and if the matching conditions of a certain group of detection ranges are matched with the detection conditions and the wire core parameters of a certain wire core, the group of detection ranges are determined to be standard detection ranges matched with the current wire core.

Further, judging whether curve parameters of each wire core detection curve are matched with range values of all detection items in the corresponding standard detection range, namely judging whether the curve parameters are located in the range values of all detection items, and judging that the wire core detection curve accords with all detection items in the detection standard information if the curve parameters of the wire core detection curve are matched with the range values of all detection items in the corresponding standard detection range; if the curve parameters of the wire core detection curve are not matched with the range values of a certain detection item in the corresponding standard detection range, judging that the wire core detection curve does not accord with each detection item in the detection standard information. The curve parameters are numerical information extracted from the wire core detection curve and used for reflecting the characteristics of the wire core detection curve. The wire core detection curve of the wire core does not accord with each detection item in the detection standard information, namely the wire core is detected to be unqualified, and the reasons for the overlarge comprehensive loss of the wire core when the wire core transmits the electric signal are indicated to include: the reflection loss of the electric signal is greatly increased due to the uneven diameter of the wire core or the occurrence of external deformation, the crosstalk loss of the electric signal is greatly increased due to the damage of the electromagnetic shielding layer on the outer layer of the wire core, the intra-group crosstalk loss of the electric signal is greatly increased due to the uneven foaming of the insulating layer on the outer layer of the wire core, and the like.

In an embodiment, the determining whether the curve parameters of the wire core detection curves are all matched with the range values of the detection items in the corresponding standard detection range includes: calculating a wire core intensity coefficient corresponding to each frequency value in each wire core detection curve; performing numerical arrangement on the wire core intensity coefficients corresponding to the strand cores according to the detection items to obtain corresponding curve parameters; and judging whether each numerical value in the curve parameters of each strand wire core is positioned in the range value of each detection item in the corresponding standard detection range, so as to judge whether the curve parameters of each wire core detection curve are matched with the corresponding standard detection range.

Specifically, the core intensity coefficient corresponding to each frequency value in each core detection curve can be calculated first, where the core intensity coefficient is used to represent the overall intensity of the received electric signal at the corresponding frequency value. Specifically, the core strength coefficient can be calculated based on the signal strength and the signal drift range in the core detection curve, and a specific calculation formula can be expressed by adopting a formula (6).

Wherein fe is the rated frequency of the transmitted detection signal, fr is the lowest frequency in the signal drift range, ft is the highest frequency in the signal drift range, p _i For the signal intensity, T, of the cable core detection curve with the frequency value of i _i Is the core strength coefficient corresponding to the frequency value i.

Further, after the strength coefficients of the wire cores corresponding to the frequency values contained in the test electric wave frequency are obtained, the strength coefficients of the wire cores can be sorted to obtain corresponding curve parameters. Specifically, numerical statistics and arrangement can be performed on the plurality of wire core intensity coefficients, for example, numerical values such as an average value, a polar difference value (a difference value between a maximum wire core intensity coefficient and a minimum wire core intensity coefficient), a median value, a standard deviation, an average slope of a curve and the like of the plurality of wire core intensity coefficients are obtained through statistics and used as curve parameters of the wire cores. The average slope of the curve can be obtained by calculating the geometrical slope at each intensity coefficient point and carrying out average calculation. The geometrical slope of the intensity coefficient point is the ratio of the coefficient difference between the intensity coefficient of the wire core where the current intensity coefficient point is located and the intensity coefficient of the next adjacent wire core to the frequency change rate (0.001 MHz).
