The application provides a self-powered vehicle state
monitoring system and a detection method, relates to the technical fields of
mechanical design and
signal analysis, and effectively solves the technical problem of monitoring the running state of a vehicle without power supply; the
system comprises a top cover, a bottom cover, an electromagnetic energy collection module and a triboelectric
signal collection module, the bottom of the top cover is provided with an annular table, the top of the bottom cover is rotationally connected with a rotor
pendulum, the electromagnetic energy collection module comprises a plurality of coils and magnets, the plurality of coils are arranged on the side wall of the annular table at intervals in the circumferential direction of the annular table, and the plurality of magnets are arranged on the rotor
pendulum; the triboelectric
signal collection module comprises a friction body and a friction plate, the friction body is arranged at the bottom of the rotor
pendulum and can rotate with the rotor pendulum, and the friction plate is arranged in the bottom cover and is in contact with the friction body. In the application, the rotor pendulum is used to receive inertial
kinetic energy, and vibration characteristics are effectively transmitted, so that the application scenarios are not limited to the transportation field, and can be expanded to
mechanical vibration monitoring, wave energy collection and monitoring and the like.
