Development of requirements for logic controls of the speed lines catenary system maintenance
Objective: To develop requirements for the organization of maintenance of the catenary system based on the actual state indicated by the digital diagnostic and monitoring platform in the logic control system for high-speed traffic. Methods: An overview analysis of high-speed catenary system diagnostics and monitoring systems is applied. Results: The systems of monitoring and automated control of catenary system devices in high-speed lines have been studied. The analytical findings as regards the maintenance methods according to the preventive maintenance schedule and based on the actual state monitoring data have been presented. Requirements for diagnostic and monitoring devices of the high-speed lines catenary system have been formulated, aimed at improving the quality attributes of current collection. Practical importance: A structural diagram of quality diagnostics and monitoring for the current collection in the high-speed Current Collector-Catenary system was obtained. The design concept of a prin-cipal model of logic control of the catenary system life cycle has been developed.
