사물인터넷 기반 장력조정장치 상태 모니터링 시스템 구현

초록

The contact wire made of copper or copper alloy is installed to keep a good current collection performance between a pantograph and catenary system. The tensioning device installed in a contact and messenger wire is required to have high reliability as a major component of the feeding facility which keeps constant tension of the wires regardless of temperature changes. The maintenance of the tensioning device is generally performed by the man power. In this paper, we propose a condition monitoring system for a spring tension device using sensor network and communication based on Internet of Thing. The proposed monitoring system is composed of a structure integrated with tensioning device by applying an ultrasonic sensor with minimum power consumption and communication device. It was able to monitor the dynamic state of the tensioning device according to temperature change n real time through the displacement of ultrasonic sensor.
