摘要：传统的万年历，通过线路连接电源来实现供电，在使用过程中必须靠近电源插板才能使用，使用空间受到限制。万年历的显示功能单一，只能显示数字，而且调节时间困难。随着自动化，智能化发展，传统万年历已经不能适应更多场合的需要。

在科技发展日新月异的今天，无线供电技术和LED显示屏应用于我们生活的各个领域。本论文设计基于无线供电方式的LED旋转万年历。LED旋转万年历是通过电动机带动一列发光二极管旋转，当发光二极管转到不同的位置时，由单片机控制发光二极管的亮灭，通过人眼影像暂留方式显示图案与文字。LED万年历达到360度可视范围，大大降低了成本，功耗小，实用性强，克服了传统平板LED显示屏的不足。

本论文主要设计了一款无线供电的LED旋转万年历。其中STC12C5A32S2单片机作为主控模块芯片，时钟模块采用DS1302，通过直流电机带动底盘的转动，通过电磁感应的无线供电方式实现对旋转的LED万年历进行供电，通过LED的亮灭让我们看到动态显示的LED旋转万年历。 通过实验测试可以对系统进行不断的更新和完善，测试各模块的兼容性，确保方案设计的可行性，从而提高无线供电方式的旋转LED万年历的整体质量，满足此次设计的要求。

Abstract：The traditional calendar, to realize power supply through line connected to the power supply, in use process must be close to the power plug board to use, the use of space is limited. The calendar display single function, can only display the number, and adjust the time difficult. Along with the automation, intelligent development, the traditional calendar has been unable to meet the needs of more occasions.

Now the development of science and technology change rapidly,various fields of wireless power supply technology and LED display used in our daily life. This paper designs LED rotate rotation calendar calendar.LED wireless power supply based on a series of light emitting diodes is driven to rotate by the motor, when the light emitting diode two to a different location, by the MCU control LED light off and by the human eye image persistence display patterns and characters on the.LED calendar achieves 360 degrees of visual range, which greatly reduces the cost, low power consumption, strong practicability, overcomes the shortcomings of traditional flat LED display.

This paper mainly designs the LED rotary calendar a wireless power supply. The STC12C5A32S2 microcontroller as the main control chip module, clock module using DS1302, drive chassis through the rotation of the DC motor, through the wireless power supply of electromagnetic induction on rotating LED million years calendar for power supply, through the LED light out let us see LED rotation the dynamic display of the calendar. By testing the system can be constantly updated and improved, the test of each module to ensure compatibility, the feasibility of design, so as to improve the overall rotation of the wireless power supply LED calendar Quality to meet the design requirements of the design.
