As a preferable mode of the present embodiment, the optical cable evaluation model includes an optical cable communication quality evaluation model and an optical cable risk evaluation model.
As a preferred solution of this embodiment, the method for constructing the optical cable communication quality assessment model specifically includes:
acquiring historical attenuation data corresponding to optical cables with preset quality grades; wherein each preset quality grade comprises a priority grade, a good grade, a middle grade and a bad grade; and determining the range of the historical attenuation data corresponding to each preset quality level according to the historical attenuation data and the wavelength corresponding to the optical communication in the optical cable, so that each range of the historical attenuation data corresponds to one preset quality level, and constructing an optical cable communication quality evaluation model.
It can be understood that the optical cable communication quality evaluation model mainly judges the optical path communication quality through the attenuation value of each kilometer of the optical path. According to the signal intensity a1 emitted by the light emitting end and the signal intensity a2 received by the receiving end, the attenuation value A between two points of the light path can be calculated, and according to the attenuation value A between two points of the light path and the light path length L (kilometer), the attenuation value A' of each kilometer of the light path is calculated, wherein the specific expression is as follows: a=a1-a 2; a' =a/L.
Further, the optical path attenuation value can affect the quality of optical fiber communication, the data transmission speed can be affected when the optical attenuation is too large, and even the optical path can be interrupted when the optical attenuation is severe. The range of the historical attenuation data corresponding to each preset quality level may be, for example: the attenuation of 1560nm per kilometer is not more than 0.34 (1560 nm represents the wavelength), four quality grades are set on the basis, and when the attenuation value is more than 0.34 (including 0.34), the quality grade of the optical path is poor; when attenuation value is between 0.2 and 0.34 (including 0.2), the quality grade of the light path is medium grade; when attenuation value is between 0.1 and 0.2 (including 0.1), the quality grade of the light path is good grade; and when the attenuation value is smaller than 0.1, the quality grade of the optical path is high. Wherein, the preset values of 0.34, 0.2, 0.1 and the like can be adjusted according to national standards, industry standards and the like.
It can be understood that by acquiring the historical attenuation data corresponding to the optical cables with each preset quality level, the constructed optical cable communication quality evaluation model is ensured to have higher accuracy, and the range of the historical attenuation data corresponding to each preset quality level is determined according to the historical attenuation data and the wavelength corresponding to the optical communication in the optical cable, so that the range of each historical attenuation data is ensured to have a corresponding preset quality level, and the modeling efficiency is improved while the accuracy is ensured.
As a preferred solution of this embodiment, the method for constructing the optical cable risk assessment model specifically includes:
acquiring historical attenuation data corresponding to optical cables with preset risk levels; wherein each preset risk level comprises an extremely high grade, a medium grade, a low grade and no grade; according to the historical attenuation data, calculating a historical attenuation annual growth rate and a historical attenuation month average growth rate corresponding to the optical cable; according to the historical attenuation annual growth rate and the historical attenuation month average growth rate, calculating a historical optical cable attenuation coefficient corresponding to the optical cable; and determining the range of the historical optical cable attenuation coefficient corresponding to each preset risk level according to the historical optical cable attenuation coefficient, so that each historical optical cable attenuation coefficient corresponds to one preset risk level, and constructing an optical cable risk assessment model.
It should be noted that, the optical cable risk assessment model mainly judges the optical cable risk level through the optical cable attenuation coefficient, calculates the increase condition of the optical cable attenuation according to the historical optical path attenuation value, and then calculates the optical cable attenuation coefficient, and the related calculation formula is as follows:
b＝(A 2 ′－A 1 ′)/A 1 ′；c 1 ＝(A 21 ′－A 11 ′)/A 11 ′；d＝(c 1 +c 2 +c 3 +…+c 12 ) 12; e=d/b; wherein b is the growth rate of the decay year, A 2 ' is attenuation value of the cable per kilometer at the end of the year, A 1 ' is attenuation value of optical cable per kilometer in the early years, c 1 For the rate of increase of the decay month of one month, the same applies, c 2 Is the decay month increase rate of february, c 12 A decay month increase rate of december; a is that 21 ' is attenuation value of optical cable per kilometer at one month end, A 11 ' is the attenuation value of the optical cable per kilometer at the beginning of one month, and similarly, A 22 ' and A 12 ' means february, A 212 ' and A 112 ' means december; d is the average attenuation increase rate in months, and e is the attenuation coefficient of the optical cable.
Further, the rate of increase of the cable attenuation reflects the degradation trend of the cable, and when the rate of increase of the cable attenuation is higher, it means that the degradation speed of the cable is faster, and the risk of the cable is higher. The risk of the optical cable can be judged through the optical cable attenuation coefficient, and the optical cable attenuation coefficient standard is 30% by way of example, five risk levels are set on the basis, and when the optical cable attenuation coefficient is more than 30% (including 30%), the optical cable risk level is extremely high; when the cable attenuation coefficient is more than 20 percent (including 20 percent), the risk level of the cable is high; when the cable attenuation coefficient is more than 10 percent (including 10 percent), the risk level of the cable is medium; when the attenuation coefficient of the optical cable is more than 5 percent (including 5 percent), the risk level of the optical cable is low; and when the attenuation coefficient of the optical cable is less than 5%, the risk level of the optical cable is zero. Wherein, the preset values of 30%, 20%, 10%, 5% and the like can be adjusted according to actual conditions.
It can be understood that by acquiring the historical attenuation data corresponding to the optical cables of each preset risk level, the constructed optical cable risk assessment model is ensured to have higher accuracy, the historical attenuation annual growth rate and the historical attenuation month average growth rate are calculated according to the historical attenuation data, the historical optical cable attenuation coefficient is further determined, the range of the historical optical cable attenuation coefficient corresponding to each preset quality level is further determined, the range of each historical optical cable attenuation coefficient is further ensured to correspond to one preset risk level, and modeling efficiency is improved while accuracy is ensured.
As a preferred scheme of the embodiment, after the risk assessment result of the optical cable is obtained and the optical fiber communication quality grade and the optical cable risk grade are obtained, the optical fiber communication quality grade can be displayed in a list and a sector diagram, wherein the list displays detailed average attenuation value per kilometer and the optical fiber quality grade of each optical path, and the sector diagram displays the distribution condition of the optical fiber quality grade; the optical cable risk levels are displayed in the form of a list and a combined graph, wherein the list displays the optical cable risk levels, and the combined graph displays the attenuation increase rate and average attenuation value of each optical cable in the past year; the specific form of the combined graph is as follows: the horizontal axis represents years, the left vertical axis represents attenuation growth rate, the right vertical axis represents average attenuation value, the bar graph shows the average attenuation value of the optical cable in years, and the line graph shows the attenuation growth rate of the optical cable in years.
