摘　　要：本文通过磁耦合共振的无线输电技术实现了对旋转LED主板的供电,并研制出一套旋转式LED点阵显示演示仪;通过STC12C5A32S2单片机实现对LED的控制和显示;通过红外通信实现对显示字符的红外操作;通过电机驱动实现LED的旋转显示。通过对旋转主板和底座主板的设计,实现了LED旋转显示的功能。该演示仪在实验和教学中起到了良好的演示效果。This paper realized the power supply to the rotating LED motherboard through wireless transmission technology of magnetic coupling resonance,and developed a set of nested type wireless transmission demonstra-tion instrument;the MCU STC12 C5 A32 S2 to control the LED and display;through the infrared operation show the character of the implementation of infrared communication;driven by the motor rotating display implemen-tation of LED. Through the design of rotating board and the base board, the realization of the LED rotary display functions. The demonstration instrument played a good demonstration effect in experiment and teach-ing.
