PURPOSE: A multifunctional detection device of railway vehicles, using a power generator containing a piezoelectric element, is provided to easily check the location and operating information of a train by increasing the response speed of a sensor module. CONSTITUTION: A power generation part(10) generates electric energy by using vibration or pressure. A sensor part(20) detects the voltage in the power generation part. A communications part(30) transmits collected information detected at the sensor part. A monitoring part(40) displays the location and operating information of a train. The monitoring part uses the voltage information received from the communications part.
