The invention provides a self-powered rail transit facility monitoring device and system.The device comprises a rail vibration energy capturing device, an energy storage circuit, a vibration awakening circuit and a data acquisition and transmission controller, the device can collect and store energy generated by rail vibration, and when the energy reaches a specified level, the vibration awakening circuit awakens the vibration awakening circuit; and the vibration wake-up circuit activates the dormant data acquisition and transmission controller so as to monitor the rail transit facilities and send the monitoring data to a remote data center. Self power supply of the wireless sensor network can be realized by utilizing a vibration energy capture technology, and ultra-low power consumption rail transit infrastructure measurement is realized by optimizing the power consumption of the sensor node, so that the energy captured by vibration can meet the requirement of long-term work of the sensor node, and the problem of power supply of a ground sensor is solved.
