Abstract:

The normal operation of catenary is the premise of the operation safety of electrified railway, so real-time monitoring and regular maintenance are necessary. In view of the lack of the current catenary maintenance program, a catenary maintenance plan based on ID3 decision tree algorithm is proposed and implemented in the catenary safe operation online monitoring system. The catenary maintenance solution based on ID3 decision tree algorithm which uses the Analysis Services technology in SQL Server2012 tool multi-dimensional mode, is used to preprocess abnormal or faulty data of catenary, ID3 decision tree algorithm is used to mine and analyze the processed data samples to build a decision tree model. Through the decision tree, the main factors affecting the abnormality or failure of the main equipment of the catenary is discovered in order to obtain a relatively scientific and reasonable maintenance plan. Taking the historical fault data of a piece of equipment of the catenary as an example, the feasibility of the scheme is verified through analysis and calculation. Therefore, the catenary maintenance plan based on the ID3 decision tree algorithm not only improves the scientific efficiency and the intelligence level of the catenary maintenance operation, but also provides reference for related staffs to choose the maintenance plan.

Key words: Catenary, ID3 decision tree algorithm, data mining, maintenance plan
