Contact network operation and maintenance method and device based on space-time distribution technology

Abstract

The invention discloses an overhead line system operation and maintenance method and device based on a space-time distribution technology. The method comprises the following steps: acquiring overhead line system bird nest historical data and overhead line system bird nest generation cause factor historical data; on the basis of the acquired historical data, constructing a catenary nest time distribution prediction model, and performing catenary nest time distribution prediction by using the time distribution prediction model; based on the acquired historical data, training to obtain a catenary bird nest cause factor weight prediction model, and performing catenary bird nest spatial distribution prediction by using the catenary bird nest cause factor weight prediction model; and determining and outputting an overhead line system fault prevention and maintenance strategy according to the overhead line system bird nest time distribution prediction result and the overhead line system bird nest space distribution prediction result. According to the method, the bird nest distribution of the contact network is accurately predicted from the two dimensions of time and space, so that more comprehensive and reliable data support is provided for fault prediction and maintenance of the contact network.

Description

technical field [0001] The invention belongs to the technical field of catenary fault prevention and data mining, and in particular relates to a catenary operation and maintenance method and device based on a spatiotemporal distribution technology. Background technique [0002] There are many factors that lead to the failure of the catenary. At present, two factors are mainly considered: one is the weather factor, and the other is the human damage factor. Therefore, these two factors are mainly considered in the process of catenary fault diagnosis and prediction. [0003] Bird activities can easily lead to short-circuit, tripping, and mechanical compensation device jamming and failure of catenary transmission lines, which will cause transportation disturbances to electrified railways and seriously affect the power supply safety of electrified railways. The main form of catenary bird damage is that birds build bird nests on the catenary system. In order to reduce trips and ...

AI Technical Summary

Problems solved by technology

[0004] At present, the impact of bird activities on catenary faults is not considered in the existing catenary fault prediction technology, which reduces the reliability and accuracy of catenary fault prediction and cannot provide more comprehensive and reliable data support for relevant operation and maintenance departments and technical support
