Problems solved by technology

However, in some remote areas, the shortage of external power supply and the difficulty of personnel arrival have brought difficulties to the establishment of wireless monitoring systems for the health status of track structures in these areas.
Battery power supply is a commonly used solution at present, but the battery capacity is limited, and the exhaustion of the battery means the end of the life of the sensor node, which brings challenges to the realization of the health monitoring of the track structure's full life cycle

Abstract

The present invention provides an electromagnetic vibration transducer, a sensing device and a track state monitoring system, and relates to the energy technology field. The electromagnetic vibration transducer comprises a coil, a hollow body, a first magnet, a second magnet and a third magnet, the coil sleeves the hollow body along the axial direction of the hollow body, the first magnet is arranged at one end of the hollow body, and the second magnet is arranged at the other end. Under the repulsive force action of the first and second magnets, the third magnet suspends in the hollow body. When the electromagnetic vibration transducer vibrates, the third magnet generates the relative vibration with the first and second magnets, so that the coil generates an induction current to convert the vibration kinetic energy into the electric energy based on the law of electromagnetic induction, and the autonomous power supply is realized.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to an electromagnetic vibration energy transducing device, a sensing device and a track state monitoring system. Background technique [0002] As the main mode of transportation, railway plays an indispensable role in national life. The speed of railway operation continues to increase, and the scale of the road network continues to increase. How to quickly and effectively maintain and manage the track structure and other infrastructure without affecting the normal operation of the railway is a huge challenge that railway managers need to face. The application of track structure health status monitoring system based on technologies such as sensors, communications, data storage, and data mining can help operators systematically grasp the service status of railway track structures in their jurisdictions, make reasonable maintenance decisions, avoid accidents, and improve management eff...
