AI Technical Summary
Technical Problem
Existing train rails are prone to warping due to temperature changes, leading to friction and potential derailments, and existing monitoring systems require external power sources, which are not self-sufficient.
Method used
An energy harvesting magnetic device installed between train rails generates power from train wheel pressure to monitor rail temperature, incorporating a support member, lifting base, power generation unit, power storage, temperature sensor, and control unit, with optional vibration and humidity sensors to detect rail conditions.
Benefits of technology
The device self-generates power for rail monitoring, operates without batteries, and predicts rail damage by analyzing sensor data, enabling timely maintenance and preventing accidents.

Abstract
The present invention relates to an energy harvesting magnetic device for monitoring the temperature of a rail, and more specifically, to an energy harvesting magnetic device for monitoring the temperature of a rail that is installed between train rails to generate power through pressure provided by the wheels of the train and uses the generated power to monitor the condition of the rail. According to an embodiment of the present invention, an energy harvesting magnet device for monitoring the temperature of a rail is provided, which is installed between a pair of train rails and can monitor the condition of the rails by measuring the temperature of the train rails, comprising: a support member installed between the pair of rails; a lifting / lowering base installed on the upper sides of the support member and raised / lowered by the pressure of a moving train wheel; a power generation unit that generates power through the lifting / lowering of the lifting / lowering base; a power storage unit that stores the power generated through the power generation unit; a temperature sensor installed on one side of the support member to measure the temperature of the train rails; and a control unit that receives temperature data measured by the temperature sensor.
