Research And Development Of Online Monitoring Management System For The Safe Operation Of Catenary Power Supply

The catenary is a network that supplies power to electric locomotive.Because of its non-backup,complex structure,and open-air installation,it needs to be monitored and repaired.At present,most of the catenary monitoring uses manual inspection methods,misjudgment often occurs for human factors,and real-time monitoring cannot be achieved;the monitoring of maintenance operation ground lines is a traditional manual management mode,which is difficult to meet the rapid development of electrified railways,and there are problems such as blind maintenance,overhaul,and difficulties in monitoring.Therefore,aiming at the problems in catenary monitoring and maintenance ground management,this paper develops an online monitoring management system for the safe operation of catenary power supply.The online monitoring management system for the safe operation of catenary power supply monitors the electrical nodes of the main conductive circuit of catenary,the power cable joints,and the grounding wire of catenary maintenance work in real time.The system uses classification and aggregation algorithms to process and store the real-time data uploaded by the temperature monitoring terminal,cable joints monitoring terminal and ground wire monitoring terminal,and display it on the corresponding page in real time through Chart and MapXtreme controls and Baidu map API to build a platform.Use clustering similar matching,statistics and other data processing methods to reorganize the information collected by the main conductive circuit electrical node monitoring terminal,power cable joints monitoring terminal and ground wire monitoring terminal,and visually display them on the same interface,so that the dispatcher can understand the current status of each monitoring terminal.A method which determines catenary maintenance plan based on the ID3 decision tree the daily operation and maintenance of the catenary stored in the database,and uses the ID3 decision tree algorithm to mine the data to determine the most important factors of the fault,thereby formulating the corresponding catenary maintenance plan.The online monitoring and management system for the safe operation of power supply of catenary was developed under the ASP.NET grid structure of Visual Studio 2017,which realized the online monitoring function of the contact network,the power cable joints and the maintenance grounding wire.The system software and each functional module program have passed software debugging and functional test experiments,and the test results have achieved the expected results.
