Specifically, in step S100, reliability evaluation is performed on the communication optical cable from four aspects of the accumulated failure times in two years of the communication optical cable, the high-reliability communication optical cable duty ratio, the number of hidden trouble points of the communication optical cable, and the operation environment of the communication optical cable. The fault rate condition of the communication optical cable is a data index which most intuitively reflects the reliability of the communication optical cable, and the possibility that the communication optical cable is damaged by external factors such as biting of small animals, hooking of vehicles, construction damage and the like can be objectively measured through the dimension of accumulating the fault times of the communication optical cable for nearly two years, so that the reliability degree of the communication optical cable is reflected. The communication optical cable can be divided into an OPGW optical cable, an ADSS optical cable, a common aerial optical cable, a pipeline optical cable and the like according to types, and in certain areas, because of mountain areas, the communication optical cable passes through a forest, and the events that animals bite the communication optical cable frequently occur, so that the rat-proof optical cable can effectively avoid the damage of the animals, and meanwhile, the occurrence of the events that external forces damage can be effectively reduced by the pipeline optical cable, the OPGW optical cable, the rat-proof optical cable and the pipeline optical cable are high-reliability communication optical cables, and the high-reliability optical cable duty ratio can objectively measure the reliability degree of the communication optical cable. Through daily inspection of team members, hidden dangers of the discovered communication optical cable, communication stations and communication equipment are recorded in time, a hidden danger library is established, hidden danger positions and contents are perfected, three-level hidden danger classification is established according to emergency, importance and general, and the reliability degree of the communication optical cable can be objectively measured by combining hidden dangers discovered through inspection through the hidden danger library. The operation environment where the communication optical cable is located has very important influence on the reliability and operation and maintenance difficulty of the communication optical cable, if the operation environment is a dense mountain area and tree area, the communication optical cable is easily damaged by small animals, the reliability is poor, and the operation environment of the communication optical cable can objectively measure the reliability of the communication optical cable.

Specifically, in step S200, the hidden danger of the communication device is discovered through communication maintenance defect elimination, the hidden danger of the communication device is classified according to the three-level hidden danger classification, and the hidden danger of the communication device is scored through the class classification, and the reliability score of the communication device is equal to the reliability base score of the communication device minus the hidden danger score.
Specifically, in step S300, reliability evaluation is performed on the communication site by comparing the scores of the three communication devices, i.e., the transmission device, the communication power supply, the storage battery, the data network device, the access device, and the like, in the communication site, wherein the reliability of site transmission is mainly dependent on the robustness of the in-site "transmission device, the communication power supply, the storage battery", the reliability score of the communication site transmission is limited by the "bottleneck reliability score" of the in-site "transmission device, the communication power supply, the storage battery", and thus the reliability score ps=min (Pt, pe, pa) of the communication siteWherein Pt is the dynamic score of the reliability of the transmission equipment, pe is the dynamic score of the reliability of the communication power supply, and Pa is the dynamic score of the reliability of the storage battery.
In a communication ring network, the reliability of a communication optical path is comprehensively embodied by the transmission reliability of a communication optical cable through which the optical path is routed and a source-sink communication station, and the unreliability of any one of the routing optical cables or the transmission capability of the source-sink station can bring hidden danger to the healthy operation of the transmission optical path, and the total optical power attenuation value of the optical cable through which the optical path is routed should be in a reasonable range, if the optical path attenuation value is overlarge, the operation of the optical path is hidden danger. And calculating the bottleneck score (minimum score of the passing communication optical cable) of the optical cable according to the reliability score data of the bottom optical cable resource by taking the optical cable routing path of the optical path as a basis, and comprehensively evaluating the reliability state and the optical path attenuation of the communication stations at the two ends of the optical path. The dynamic score of the optical path reliability is a bottleneck score of the optical cable route and a smaller value of the dynamic score of the transmission reliability of the 'source-destination' communication station, the influence of the attenuation deviation degree of the optical path is considered on the basis, the health state of the optical path is displayed according to the reliability score of the optical path, specifically, the reliability score of the communication optical path in step 400 is Pr,
Wherein,
Wherein,
Pst denotes the reliability dynamic score of the communication path "source" communication site, psr denotes the reliability dynamic score of the communication path "sink" communication site, R denotes the set of reliability dynamic scores of the communication path routes through the communication optical cable, wherein plm denotes the mth optical cable route of the communication path,The function is used for calculating the attenuation deviation degree of the communication optical path, the Line (r) represents the total length of the optical cable route, the Atten (r) function is used for calculating the attenuation value of the communication optical path, cr represents the reasonable attenuation base factor of the communication optical cable, and Cq represents the attenuation weight factor of the communication optical path, wherein Cr and Cq are constants.
