[0076] The following will be combined Figure 2 Steps S110 to S140 are explained and illustrated in detail.

[0077] In step S110, the power outage time and battery pack data of the target site are obtained, and the relative power supply stability index of the target site is determined according to the power outage time and the battery pack data.

[0078] The power outage time of the target site within a preset time period may be obtained, which may be the power outage time within one year to the present time or the power outage time within half a year to the present time, which is not specifically limited in the present example embodiment.

[0079] In this example embodiment, reference Figure 3As shown, obtaining the power outage time and battery pack data of the target site, and determining the relative power supply stability index of the target site according to the power outage time and the battery pack data may include steps S310 to S340:

[0080] Step S310. Obtain a preset time period and a power outage time within the preset time period, and determine the power availability of the target site according to the preset time period and the power outage time within the preset time period;

[0084] In the following, step S310 to step S340 will be explained and illustrated. Specifically, first, a preset time period for calculating the power outage time of the target site and a time unit of the preset time period can be determined; then, according to the determined preset time period, the power outage time of the target site within the preset time period is obtained from the network management alarm based on the preset time period, and the power availability I of the target site is determined according to the preset time period and the power outage time within the preset time period. 11 , the calculation of power availability can refer to equation (1)

[0085]

[0086] Next, the battery pack data of the target site can be obtained, wherein the battery pack data may include: the number of battery packs, the battery capacity, and the operating current of the battery when working, and the relative battery life index of the target site can be obtained based on the number of battery packs, the battery capacity, and the operating current of the battery when working included in the battery pack data; finally, the relative power supply stability index of the target site can be obtained based on the power availability rate and the relative battery life index of the target site.

[0087] Further, in this exemplary embodiment, reference is made to Figure 4 As shown, obtaining the relative endurance index of the target site according to the number of battery packs, battery capacity, and operating current may include steps S410 to S430:

[0088] Step S410. Determine the absolute endurance index of the target site when the power supply of the target site is interrupted according to the number of battery packs, the battery capacity and the operating current;

[0090] Step S430: Obtain a relative battery life index of the target site according to the battery continuous working time reference critical value and the absolute battery life index.

[0091] Specifically, first, according to the number of battery packs, the battery capacity, and the working current of the battery, the absolute working time of the battery of the target site when the power supply is interrupted is determined, that is, the absolute endurance index of the target site, wherein the absolute endurance index of the target site is I 12 The calculation of ′ is as follows:

[0092]

The absolute endurance index can be converted into a relative endurance index by referring to the critical value η of the battery continuous working time, where the percentage system can be processed and the converted relative endurance index is mapped within [0,100]. The calculation of the relative endurance index is equation (3)

[0094]

[0095] Among them, I 12,i is the relative battery life index of the i-th base station site battery that needs to be rated, I 12,i ′ is the absolute battery life index of the i-th base station site battery that needs to be rated, (I 12 ′) max is the maximum value of the absolute battery life index of all base stations to be evaluated, and η is the reference critical value of the continuous working time of the base station battery. 12,i When the value of ′-η) is negative, the value of the relative endurance index of the base station is 0.

[0096] After obtaining the power availability of the target site and the relative battery life of the base station site, the relative power supply stability index of the base station site can be obtained according to the power availability and the relative battery life. The calculation formula of the relative power supply stability index can refer to equation (4) as shown in

[0097] I 1，i =I 11,i I 12,i (4)

[0098] Among them, I 1，i is the relative power supply stability index of the i-th base station site to be rated, I 11,i is the power availability of the i-th base station site with the required rating, I 12,i is the relative endurance index of the battery of the i-th base station site that needs to be rated.

[0099] For example, when the preset time period is 365 days and the time unit of the preset time period is minutes, the total time interval is 365*24*60=525600 minutes, and the power outage times of the 10 base station sites are obtained as shown in Table 1.

[0100] According to equation (1), the power availability of the 10 base station sites can be obtained. The power availability of the 10 base station sites is shown in Table 2.

[0103] Table 2 Power availability of each base station

[0104]

[0105] Wherein, power available time = total time interval - power interruption time. When the battery continuous working time in the area where the 10 sites are located refers to the critical value η = 3*60 = 180, the battery group data of the 10 base station sites can refer to Table 3:

[0106] Table 3 Battery data of each base station

[0107] Site number Number of battery packs Battery capacity (Ah) Working current (A) 1 2 38 25 2 1 100 25 3 1 150 25 4 2 100 30 5 2 150 25 6 1 300 30 7 2 160 30 8 2 150 20 9 2 200 25 10 2 200 30

[0108] According to the reference critical value of the battery continuous working time in the area, the battery group data of the 10 base station sites and the calculation equation (3), the absolute endurance index and the relative endurance index of the 10 base station sites can be obtained as shown in Table 4:

[0109] Table 4 Absolute endurance index and relative endurance index of each site

[0110] Site number Absolute battery life index (minutes) Relative battery life index (-) 1 182.40 0.31 2 240.00 7.69 3 360.00 23.08 4 400.00 28.21 5 720.00 69.23 6 600.00 53.85 7 640.00 58.97 8 900.00 92.31 9 960.00 100.00 10 800.00 79.49

The relative stability index of power supply obtained according to equation (4) can be shown in Table 5:

[0113]

[0114] When a base station site has multiple supporting power supplies and batteries, the relative power supply stability indexes of the multiple supporting power supplies and batteries can be calculated, and the minimum value of the multiple relative power supply stability indexes is used as the relative power supply stability index of the base station site.

[0115] In step S120, the received optical power and the distribution optical cable data of the target site are obtained, and the relative transmission optical path stability index of the target site is determined according to the received optical power and the distribution optical cable data.

[0122] In the following, step S510 to step S540 will be explained and illustrated. Specifically, first, the received optical power of the uplink baseband processing unit side of the target base station site and the critical value of the received optical power are obtained, wherein the critical value of the received optical power can be used as the critical value λ of the absolute optical cable effective connection index of the base station site, and the received optical power of the uplink baseband processing unit side can be used as the absolute optical cable effective connection index I of the target site. 21 ′, after obtaining the critical value of the absolute optical cable effective connection index and the absolute optical cable effective connection index, the absolute optical cable effective connection index can be processed into a percentage according to the critical value of the absolute optical cable effective connection index to obtain the relative optical cable effective connection index. The calculation equation of the relative optical cable effective connection index can refer to equation (5):

[0123]

[0124] Among them, I 21,i is the relative optical cable effective connection index of the i-th base station site that needs to be rated, I 21,i ′ is the absolute optical cable effective connection index of the i-th base station site to be rated, (I 21 ′) max is the maximum value of the absolute optical cable effective connection line index of all base station sites to be evaluated, and λ is the critical value of the absolute optical cable effective connection index of the base station site. 21,i When the value of ′-λ) is negative, the relative optical cable effective connection index value of the base station site is 0.

[0125] After obtaining the relative optical cable effective connection index of the target base station site, the number of distribution optical cables of the target site can also be obtained, and the relative route allocation rationality index of the target site is determined according to the obtained number of distribution optical cables; finally, the relative transmission optical path stability index of the target site is obtained according to the relative optical cable effective connection index and the relative route allocation rationality index of the target site.

[0126] Further, refer to Figure 6 As shown, obtaining the number of distribution optical cables of the target site and obtaining the relative route allocation rationality index of the target site according to the number of distribution optical cables may include steps S610 to S640:

[0127] Step S610. Obtain a reasonable reference value for absolute route allocation of the target site according to the number of the distribution optical cables;

[0128] Step S620. Obtain the total number of sectors of the target site and the minimum number of sectors remaining and available when a distribution optical cable in the target site is disconnected;

[0129] Step S630. Obtain the absolute route allocation rationality index of the target site through the total number of sectors and the remaining minimum number of sectors that can be used;

[0130] Step S640: Obtain the relative route allocation rationality index of the target site according to the absolute route allocation rationality index and the absolute route allocation rationality reference value.

[0131] In the following, step S610 to step S640 will be explained and illustrated. Specifically, first, the number of distribution optical cables of the target site can be obtained, and the absolute route allocation reasonable reference value θ of the target site can be obtained according to the number of distribution optical cables of the target site. The calculation formula of the absolute route allocation reasonable reference value can refer to equation (6):

[0132]

[0133] Then, the total number of sectors of the target site and the minimum number of sectors that can be used when any distribution optical cable in the target site is interrupted are obtained, and the absolute route allocation rationality index I of the target site is determined according to the total number of sectors of the target site and the minimum number of sectors that can be used 22 ′, where the calculation formula of the absolute routing allocation rationality index can refer to equation (7)

[0134]

[0135] Finally, the absolute route allocation rationality index of the target site can be processed into a percentage according to the absolute route allocation rationality index of the target site and the absolute route allocation rationality reference value to obtain the relative route allocation rationality index of the target site. The calculation formula of the relative route allocation rationality index of the target site can refer to equation (8):

[0136]

[0137] Among them, I 22,i Assign a reasonable index to the relative routing of the i-th base station site with the required rating, I 22,i ′ is the absolute routing allocation rationality index of the i-th base station site with the required rating, θ i Assign a reasonable reference value to the absolute route of the i-th base station. i When it is 0, the value of the relative routing allocation rationality index of the base station site is 0.

[0138] After the relative optical cable effective connection index and the relative route allocation rationality index of the target site are obtained, the relative transmission optical path stability index of the target site can be obtained according to the relative optical cable effective connection index and the relative route allocation rationality index of the target site. Specifically, first, the first weight factor ω1 of the relative optical cable effective connection index and the second weight factor ω2 of the relative route allocation rationality index are determined according to the target site, where ω1+ω2=1, and then the relative transmission optical path stability index of the target site is obtained according to the first weight factor and the second weight factor. The calculation formula of the relative transmission optical path stability index can refer to equation (9)

[0139] I 2,i =ω1I 21，i +ω2I 22，i (9)

[0140] Among them, I 2，i is the relative transmission optical path stability index of the i-th base station site that needs to be rated, I 21，i is the relative optical cable effective connection index of the i-th base station site that needs to be rated, I 22，i Assign a reasonableness index to the relative routing of the i-th base station site of the desired rating.

[0141] For example, the critical value of the absolute optical cable effective connection index λ=-13dbm, and the absolute optical cable effective connection indexes of 10 base station sites are obtained as shown in Table 6:

[0142] Table 6 Absolute optical cable effective connection index table of each base station site

[0143] Site number Absolute optical cable effective connection index (dbm) 1 -5 2 -12 3 -10 4 -7 5 -9 6 -19 7 -12 8 -16 9 -8 10 -11

[0144] According to the absolute optical cable effective connection index in Table 6 and equation (5), the relative optical cable effective connection index of each base station site can be obtained. The relative optical cable effective connection index of each base station site can be shown in Table 7:

[0145] Table 7 Relative optical cable effective connection index of each base station site

[0146] Site number Absolute optical cable effective connection index (dbm) Relative optical cable effective connection index (-) 1 -5 100 2 -12 12.5 3 -10 37.5 4 -7 75 5 -9 50 6 -19 0 7 -12 12.5 8 -16 0 9 -8 62.5 10 -11 25

[0147] At the same time, the number of distribution optical cables in each base station site is shown in Table 8. According to the number of distribution optical cables in each base station site in Table 8 and equation (6), the reasonable reference value of absolute route allocation of each base station site can be obtained. The obtained reasonable reference value of absolute route allocation of each base station site is the reasonable reference value θ of absolute route allocation in Table 8.

[0148] Table 8 Reasonable reference value table for absolute route allocation of each base station

[0149] Site number Number of distribution optical cables Reasonable reference value θ for absolute routing allocation 1 2 0.5000 2 1 0.0000 3 2 0.5000 4 3 0.6667 5 1 0.0000 6 2 0.5000 7 3 0.6667 8 3 0.6667 9 3 0.6667 10 3 0.6667

[0150] Furthermore, the total number of sectors of each base station site and the minimum number of sectors remaining available when a distribution optical cable in each base station site is terminated are shown in reference Table 9. According to equation (7) and the total number of sectors in each base station site and the minimum number of sectors remaining available when a distribution optical cable is disconnected in Table 9, the absolute routing allocation rationality index of each base station site in Table 9 can be obtained.

[0151] When the absolute route allocation reasonable reference value θ in Table 8 and the absolute route allocation reasonable index in Table 9 are obtained, the relative route allocation reasonable index of each base station site can be obtained according to equation (8), as shown in reference Table 10.

[0152] Table 9 Reasonable index of absolute routing allocation of each base station

[0153]

[0154] Table 10 Relative routing allocation rationality index table of each base station site

[0155]

[0156] After obtaining the relative optical cable effective connection index in Table 7 and the relative route allocation rationality index in Table 10, with the first weight factor ω1 of the relative optical cable effective connection index = 0.5 and the second weight factor ω2 of the relative route allocation rationality index = 0.5, the relative transmission optical path stability index of each base station site can be obtained as shown in Table 11:

[0157] Table 11 Relative transmission optical path stability index of each base station

[0158]

[0159] In step S130, a board temperature and a site type of a radio remote unit of the target site are obtained, and a relative environmental stability index of the target site is determined according to the board temperature and the site type.

[0160] In this example embodiment, reference Figure 7 As shown, obtaining the board temperature and site type of the radio remote unit of the target site, and determining the relative environmental stability index of the target site according to the board temperature and the site type may include steps S710 to S740:

[0161] Step S710: Obtain the maximum value of the board temperature of the radio remote unit of the target site and the reference critical value of the board temperature index;

[0162] Step S720: Determine the relative temperature suitability index value of the target site according to the maximum value of the single board temperature and the critical reference value of the single board temperature index;

[0163] Step S730. Determine the site type of the target site, and determine the target site type stability factor according to the site type;

[0164] Step S740: Obtain a relative environmental stability index of the target site according to the relative temperature suitability index value and the target site type stability factor.

[0165] Specifically, first, the reference critical value α of the board temperature index of the remote radio unit (RRU) of the base station site can be obtained, and the maximum value I of the board temperature of the remote radio unit of the target site can be obtained through the alarm information of the network management system. 31 ′; Then, the maximum value of the single board temperature is processed into a percentage by using the single board temperature index reference critical value to obtain the relative temperature suitability index value of the target site. The calculation of the relative temperature suitability index value of the target site can refer to equation (10):

[0166]

[0167] Among them, I 31，i is the relative temperature suitability index value of the i-th base station site to be rated, I 31，i ′ is the maximum value of the board temperature of the RRU of the i-th base station site to be rated, (I 31 ′) min is the minimum value among the highest values ​​of the board temperature of multiple base station sites RRUs that need to be rated, and α is the reference critical value of the board temperature index. 31,i ′) is negative, the relative temperature suitability index value of the base station site is 0.

[0168] After obtaining the relative temperature suitability index value of the target site, the target site type stability factor can also be determined according to the site type of the target site. Specifically, different site types have different effects on the environmental stability of the base station site, wherein the site type can be a computer room type site, a cabinet type site, or a wall-mounted site. In this example embodiment, the site type is not specifically limited. The value of the site type stability factor of sites of different site types is not greater than 1. After obtaining the site type stability factor of the target site and the relative temperature suitability index value of the target site, the relative environmental stability index of the target site can be obtained according to the site type stability factor and the relative temperature suitability index value of the target site. Among them, the calculation of the relative environmental stability index of the target site can refer to equation (11)

[0169] I 3,i =I 31,i *I 32,i (11)

[0170] Among them, I 3,i is the relative environmental stability index of the i-th base station site to be rated, I 31,i is the relative temperature suitability index value of the i-th base station site to be rated, I 32,i is the site type stability factor of the i-th base station site that requires rating.

[0171] For example, the maximum values ​​of the board temperatures of the radio remote units of 10 base station sites are shown in Table 12. When the reference critical value of the board temperature index of the RRU is 70 degrees Celsius, the relative temperature suitability index values ​​of the 10 base station sites can be obtained according to equation (11). The relative temperature suitability index values ​​of the 10 base station sites are shown in Table 12:

[0172] Table 12 Relative temperature suitability index values ​​of each base station site

[0173]

[0174] When the site type stability factor value of the computer room site in the site type is 1, the site type stability factor value of the cabinet site is 0.9, and the site type stability factor value of the wall-mounted site is 0.9, the relative environmental stability index of each site can be obtained according to the values ​​of the site type stability factors of different sites shown in Table 13, the relative temperature adaptability index values ​​in Table 12, and equation (11). The relative environmental stability index of each site can be shown in Table 13:

[0175] Table 13 Relative environmental stability index of each site

[0176]

[0177] In step S140, an evaluation factor of the target site is determined according to the relative power supply stability index, the relative transmission optical path stability index, and the relative environmental stability index, and maintenance measures for the target site are determined according to the evaluation factor.

[0178] In this example embodiment, reference Figure 8 As shown, determining the evaluation factor of the target site according to the relative power supply stability index, the relative transmission optical path stability index, and the relative environmental stability index, and determining the maintenance measures for the target site according to the evaluation factor may include steps S810 to S830:

[0179] Step S810. Determine a first weight factor, a second weight factor, and a third weight factor corresponding to the relative power supply stability index, the relative transmission optical path stability index, and the relative environmental stability index, respectively;

[0180] Step S820. Obtain an evaluation factor of the target site according to the relative power supply stability index, the first weight factor, the relative transmission optical path stability index, the second weight factor, the relative environmental stability index, and the third weight factor;

[0181] Step S830: Classify the target site based on the evaluation factor, and determine the maintenance measures corresponding to the target site according to the classification level of the target site.

[0182] In the following, step S810-step S830 will be explained and illustrated. Specifically, after obtaining the relative power supply stability index, relative transmission optical path stability index and relative environmental stability index of the target site, the first weight factor corresponding to the relative power supply stability index, the second weight factor corresponding to the relative transmission optical path stability index, and the third weight factor corresponding to the relative environmental stability index can be determined, and the evaluation factor of the target site is determined according to the first factor, the second factor and the third factor, and the target site is classified according to the evaluation factor of the target site, and the maintenance measures for the target site are determined according to the classification level of the target site. When classifying the target site, the sites ranked in the top 30% can be classified as first-level sites, the sites ranked in 30%-70% can be classified as second-level sites, and the sites ranked in the bottom 30% can be classified as third-level sites. In this example embodiment, the classification of the target site is not specifically limited. The sum of the first weight factor n1, the second weight factor n2 and the third weight factor n3 is 1. In this example embodiment, the values ​​of the first weight factor, the second weight factor and the third weight factor are not specifically limited.

[0183] For example, when n1=n2=n3=1 / 3, and the base station classification rule is to classify the sites ranked in the top 30% as first-level sites, the sites ranked between 30% and 70% as second-level sites, and the sites ranked in the bottom 30% as third-level sites, the evaluation factors of the 10 base station sites and the classification levels of the 10 base station sites can be obtained through the relative power supply stability index shown in Table 5, the relative transmission optical path stability index shown in Table 11, and the relative environmental stability index shown in Table 13, as shown in Table 14:

[0184] Table 14 Evaluation factors and classification levels of each site

[0185]

[0186] In Table 14, sites with site numbers 7, 8, and 9 are first-level sites with the best health and little impact on business perception. No special maintenance and management are required, and routine inspection and maintenance work can be performed. Site numbers 1, 4, 5, and 10 are second-level sites with moderate health and slightly greater impact on business perception. They should be given appropriate attention and management, monitor the operating status of the equipment, and allocate inspection and maintenance resources as needed. Site numbers 2, 3, and 6 are third-level sites with the greatest impact on business perception. They should be given special attention and management, closely monitor the operating status of the equipment, and perform inspections and maintenance operations in a timely manner.
