However, the power supply for equipment along railway lines currently faces many challenges.

[0003] Traditional centralized power supply methods require laying a large number of transmission lines due to the wide and dispersed distribution of equipment along railway lines.

Figure 1 As shown, it includes: Electromagnetic induction power extraction module 1 is used to extract power from the power supply line next to the railway track, including a flexible iron core, an energy extraction coil wound on the flexible iron core, and a clamping protection circuit. Wind power generation module 2 includes a wind turbine generator; the wind turbine generator is installed along the railway line at a location where there are no continuous obstructions between its wind energy collection surface and the prevailing wind direction.

[0027] This invention integrates electromagnetic induction power generation, wind power generation, and solar power generation to construct an intelligent hybrid power supply system for railway lines. Through a flexible iron core design and clamping protection circuit, efficient non-contact power extraction from the power supply line is achieved; combined with wind and solar power generation, it effectively overcomes the limitations of single-energy supply. Each energy module is optimized and managed by a dedicated controller, collaboratively powering battery pack 7, which then provides stable power to railway line equipment via voltage stabilization unit 10. This system features high power supply reliability, strong environmental adaptability, and convenient maintenance, solving the power extraction problem in remote sections while also offering green and environmentally friendly advantages, meeting the needs of modern intelligent railway development.

[0028] The magneto-electric controller 4 includes a rectifier circuit, a filter circuit, and a dynamic adjustment circuit. The rectifier circuit converts the alternating current induced by the energy harvesting coil into direct current. The filter circuit filters out ripple in the direct current. The dynamic adjustment circuit dynamically adjusts the output voltage and current according to the charging requirements of the battery pack 7, which avoids damage to the battery from overcharging and over-discharging, and ensures the continuous and reliable operation of the power supply system, providing a safer and more stable power guarantee for equipment along the railway line.

[0029] The solar controller 6 includes a charging mode switching circuit; the charging mode switching circuit is used to switch between constant current or constant voltage charging mode according to the light intensity and the state of the battery pack 7, so as to ensure fast charging under strong light conditions and maintain a stable charging process when the light is insufficient.

[0030] In one embodiment of this utility model, a status display and communication unit 8 is further included. This unit 8 is connected to the magnetoelectric controller 4, wind power controller 5, solar power controller 6, and battery pack 7, respectively. It is used to display the real-time operating status of each generator module and the charging / discharging status of the battery pack 7, and to transmit equipment operation data to a remote monitoring terminal. This unit can collect and intuitively display the operating parameters and battery status of each generator module in real time, enabling maintenance personnel to quickly grasp the equipment's operating status. Simultaneously, by remotely transmitting key data to the monitoring center, intelligent operation and maintenance management of the equipment is achieved, facilitating the timely detection and handling of potential problems.

Simultaneously, a clamping protection circuit is equipped to prevent overvoltage pulses from the energy extraction coil outputting and damaging downstream equipment due to magnetic saturation of the iron core under high current. The overvoltage pulses are limited to a safe range before being connected to subsequent circuits.
