【Abstract】 Because of the power supply and communication wiring difficulties caused by the rotating mechanical components in the monitoring system, and the disadvantages of the existing conductive slip ring technology, such as easy wear and short life, this paper designed a rotating mechanical component monitoring system based on wireless power supply. Firstly, theoretical analysis, simulation verification and hardware design were conducted on the LCC-S type magnetically coupled wireless power transmission system, realizing a wireless power supply subsystem capable of non-contact wireless power transmission. Secondly, a monitoring subsystem was designed, which could collect the temperature and vibration data of multiple points in the rotating mechanical components in real time and transmit them to the upper computer via wireless communication. Finally, the effectiveness of the system was verified by building a rotating experimental platform to simulate the rotational motion of mechanical components. To sum up, the designed system provides a feasible technical solution for the wireless monitoring of rotating mechanical components.更多还原
