Embodiment 1

[0052] The following is an introduction to Embodiment 1 of a fault location method for a power communication network provided by the present application, see figure 1 , embodiment one includes:

[0053] S101. Construct a fault propagation model based on Bayesian theory according to the historical operation and maintenance data of the power communication network;

[0054] The fault propagation model includes a parent node used to represent a fault of a network device, a child node used to represent a symptom of the network device, and a connecting line used to represent the probability that the symptom is a negative symptom when the network device fails;

[0055] In order to construct the fault propagation model based on Bayesian theory as mentioned above, several important definitions used in fault location of power communication network are first given:

[0056] Symptoms: Refers to the information that can be observed during the operation of the power communication network. It...

Embodiment 2

[0071] see figure 2 , embodiment two specifically includes:

[0072] S201. Constructing a fault propagation model based on Bayesian theory;

[0073] In this embodiment, symptoms refer to information that can be observed when the power communication network is running. Specifically, this embodiment uses s j ∈S represents the symptom of service j on the power communication network, use S={s 1 ,s 2 ,...,s n} represents the set of all services on the power communication network. In order to distinguish symptom information, this embodiment defines the normal information of the power communication network as a positive symptom, using s j = 0 means that the service j on the power communication network is running normally; to define abnormal information as a negative symptom, use s j =1 means that the service j on the power communication network is in an abnormal state.

[0074] A fault refers to the cause of one or more abnormal services on the power communication network. Sp...

Abstract

The invention discloses a fault positioning method, device and equipment for a power communication network and a readable storage medium, and the method can build a fault propagation model based on the Bayesian theory according to the historical operation and maintenance data of the power communication network; in the fault positioning process, the fault propagation model is firstly segmented intoa plurality of independent sub-models based on the D-segmentation theory, and then fault positioning is realized according to the detected negative symptom set and each sub-model, so that the time consumption of the fault positioning process is remarkably reduced, and the fault positioning efficiency is improved.

Description

technical field [0001] The present application relates to the field of communication, and in particular to a fault location method, device, equipment and readable storage medium of an electric power communication network. Background technique [0002] With the rapid development of the smart grid, the number of equipment in the power communication network is increasing and the coverage is wider and wider, bringing sufficient power resources for social development and people's lives. In order to ensure the stable operation of power communication network, fault management is more and more important. In fault management work, quickly locating faulty equipment is the premise and necessary condition for fault handling. [0003] However, the existing fault location solutions take a long time and cannot meet the current needs. Contents of the invention [0004] The purpose of this application is to provide a fault location method, device, equipment and readable storage medium fo...
