Abstract: Provided is a system for real-time condition diagnosis of a bearing module including a self-power generation module installed in an outer ring of a bearing to generate electricity using vibration generated from a micro whirling motion of the bearing, a behavior detection unit installed in the bearing to detect behavior information of the bearing in real time, a wireless transmission module connected to the behavior detection unit to transmit the real-time detected behavior information of the bearing to an external device, and a condition diagnosis unit that receives the behavior information of the bearing transmitted from the wireless transmission module and diagnoses condition of the bearing in real time, wherein the real-time behavior information of the behavior detection unit installed in the bearing is transmitted through the electricity obtained by the self-power generation module.
