Fault analysis method and device based on power communication network

Abstract

The invention provides a failure analysis method and device based on a power communication network. The method comprises the following steps: acquiring history data of failures to be analyzed in the power communication network, and acquiring a failure cause type set corresponding to generated failures, wherein each cause type comprises at least one cause factor; calculating cause probabilities corresponding to the cause factors in the cause types, acquiring weights corresponding to the cause factors according to the probabilities, and acquiring failure probabilities corresponding to the cause types according to the acquired weights corresponding to the cause factors; calculating the probabilities of the failures to be analyzed according to the failure probabilities corresponding to the cause types; and if the probabilities of the failures to be analyzed are greater than a first preset threshold, performing troubleshooting in sequence from large to small according to the failure probabilities corresponding to the cause types and the weights corresponding the cause factors in the cause types.

Description

Technical field The present invention relates to power communication network technology, in particular to a fault analysis method and device based on the power communication network. Background technique At present, the power communication network is directly related to the safety of the power grid and the reliability of power supply. Therefore, it is particularly important to ensure the safety of the power communication network. With the vigorous development of the power communication network, the structure of the power communication network is becoming more and more complex, and the environment in which it is located is becoming more and more diverse. Therefore, more and more failures may occur in the power communication network. Specifically, in the power communication network, its main components, such as: Synchronous Digital Hierarchy (SDH) equipment, optical fibers, interfaces, etc., may all have failures, and the causes of failures generally come from many aspects.

Problems solved by technology

However, in the prior art, the probabilities of failures under different inducements are generally directly given manually, which is highly subjective. Therefore, manual methods cannot effectively guide the operation and maintenance of the power communication network and avoid failures in advance. occur
