Energy supply system and method for track side sensor

The invention relates to the technical field of energy, in particular to an energy supply system and method for a track side sensor. The invention discloses an energy supply system of a track side sensor. The energy supply system comprises an electrified steel rail, and an energy management module, a pull capacitor and a micro detection sensor which are electrically connected are installed on the side of the electrified steel rail; the electrified steel rail supplies power to the energy management module, the energy management module supplies power to the pull-method capacitor, and the pull-method capacitor supplies power to the micro detection sensor. The technical problem to be solved by the invention is to develop an energy supply system and method for a track side sensor, which can effectively supply power to a detection sensor on a track for a long time and does not need to replace a battery. 本发明涉及能源技术领域，特别是涉及一种轨道侧传感器的供能系统及方法。本发明公开了一种轨道侧传感器的供能系统，包括带电钢轨，带电钢轨侧安装有电性连接的能量管理模块、拉法电容器和微型检测传感器；带电钢轨向能量管理模块供电，能量管理
