The invention provides a railway track plate vibration monitoring system and monitoring method based on a friction nano electric generator. The railway track plate vibration monitoring system comprises a friction nano sensor, an energy storage unit, a logic analysis unit, a positioning unit and a transmission unit. According to the invention, the friction nano sensor is placed on the railway track plate along a railway line, track plate vibration generated by railway operation is converted into an electric signal by using the principle of the friction nano generator, and the vibration accelerated speed of the track plate is reflected through the magnitude of the electric signal, so that the purpose of monitoring the vibration state of the railway track plate is achieved. The positioning unit and the transmission unit of the monitoring system can accurately monitor the vibration state of the railway track plate in real time. The energy storage unit can store surplus electric energy, and self-energized monitoring of the system is achieved. A cheap and degradable polylactic acid material can be adopted to manufacture a sensor, so that the cost of the railway monitoring system is reduced, green pollution-free monitoring is realized, and the construction of the Internet of Things of the intelligent railway system is greatly promoted.
