Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0072] In a first aspect, this embodiment discloses Figure 1 A method for comprehensively evaluating the operation quality of a power communication network is shown, the method comprising the following steps:

[0073] Step 1: Obtain reliability performance score, transmission performance score, security performance score, and network performance score.

[0074] Among them: The reliability performance score is used to characterize the reliability of the operation of the power communication network, and the reliability is proportional to the reliability performance score. The transmission performance score is used to characterize the transmission quality of the operation of the power communication network, and the transmission quality is proportional to the transmission performance score. The safety performance score is used to characterize the safety of the operation of the power communication network, and the safety is proportional to the safety performance score. The network performance score is used to characterize the network quality of the operation of the power communication network, and the network quality is proportional to the network performance score.

[0075] Step 2: Calculate the corresponding operation and maintenance performance score based on the historical supervision data of the power communication network operation.

[0076] Among them: the supervision data is specifically the operation and maintenance records when any one or more of the reliability performance score, transmission performance score, security performance score and network performance score is abnormal. The abnormality is specifically the situation where each performance score is less than the corresponding preset performance score threshold. The operation and maintenance records include downtime equipment, downtime duration, and operation and maintenance costs. The operation and maintenance performance score is generated based on the operation and maintenance records.

[0077] Step 3: Use the operation and maintenance performance score to correct the real-time reliability performance score, the real-time transmission performance score, the real-time security performance score, and the real-time network performance score to obtain the corresponding corrected reliability performance score, corrected transmission performance score, corrected security performance score, and corrected network performance score.

[0078] Step 4: Use the modified reliability performance score, modified transmission performance score, modified safety performance score and modified network performance score to conduct a comprehensive assessment of the operation quality of the power communication network and generate early warning information.

[0079] Specifically, step one includes:

[0080] The reliability performance score is obtained based on the reliability performance parameters of the power communication network operation and normalized.

[0081] The transmission performance score is obtained by normalizing the transmission performance parameters based on the operation of the power communication network.

[0082] The safety performance score is obtained by normalizing the safety performance parameters of the power communication network operation.

[0083] The network performance score is obtained by normalizing the network performance parameters based on the operation of the power communication network.

[0084] Among them, normalization is used to process different parameters into values ​​of the same dimension.

[0085] It should be noted that the reliability performance parameters, transmission performance parameters, security performance parameters and network performance parameters in this embodiment are all related parameters well known to those skilled in the art. This embodiment obtains corresponding performance scores through normalization processing to realize the transformation of massive and complex data into specific and concise data, providing an accurate data basis for subsequent data processing. It should also be noted that the normalization processing used in this embodiment is an existing normalization processing technology, which aims to unify different data into data of the same dimension, providing a reasonable basis for subsequent data processing. In this embodiment, a number of targeted performance scores provide a data basis for the comprehensive evaluation of the operation quality of the power communication network.

[0086] Specifically, step 2 includes:

[0087] Obtain the supervision data of historical power communication network operation, and capture the corresponding relationship between the anomalies and operation and maintenance records.

[0088] Based on the operation and maintenance records, the corresponding operation and maintenance performance score is calculated using the operation and maintenance performance scoring formula, where the operation and maintenance performance scoring formula is specifically:

[0090] Among them: OE is the importance value of the downtime equipment obtained based on the preset equipment importance query table.

Therefore, the classification of equipment is achieved through the preset importance value, and the importance value is proportional to the importance of the equipment. OD is the downtime duration. OMC is the operation and maintenance cost. ζ is the operation and maintenance performance score, and the operation and maintenance performance score is inversely proportional to the operation and maintenance performance.

[0091] In this embodiment, the operation and maintenance performance score is used to quantify the data generated during the process of failure and failure repair, providing the necessary technical means for utilizing the data without causing unnecessary increase in the amount of calculation. The operation and maintenance performance score also provides a data basis for optimizing various performance scores.

[0096] Among them: PS x is the real-time reliability performance score, real-time transmission performance score, real-time security performance score or real-time network performance score. ζ is the operation and maintenance performance score. CPS x To modify the reliability performance score, modify the transmission performance score, modify the security performance score, or modify the network performance score.

[0097] This embodiment achieves the real-time nature of the comprehensive evaluation of the operation quality of the power communication network by obtaining real-time performance scores, and introduces operation and maintenance performance scores to improve the accuracy and comprehensiveness of various performance scores. At the same time, under the normalization processing in the previous article, there is no need to calculate each performance indicator with a unique calculation formula. Instead, the performance score correction formula of this embodiment is used as a general formula, thereby achieving the goal of ensuring targetedness while improving comprehensiveness.

[0098] Specifically, step four includes:

[0099] Based on the modified reliability performance score, modified transmission performance score, modified security performance score and modified network performance, a comprehensive evaluation formula is used to determine whether to generate warning information.

When ψ < 0, an over-threshold warning is generated. x_τ is the corresponding preset abnormal fluctuation threshold. || is the absolute value operator. σ is the abnormal fluctuation warning parameter. When σ>0, an abnormal fluctuation warning is generated.

[0103] In this embodiment, the evaluation results are optimized by classifying the warning information into over-threshold warnings and abnormal fluctuation warnings, thereby improving the interpretability of the evaluation results and facilitating front-line staff to use the classified warning information to quickly perform subsequent warning processing known to technical personnel in this field.
