摘要： 本次设计中的LED数码管电子时钟电路采用24小时制记时方式,本次设计采用AT89C51单片机的扩展芯片和6个PNP三极管做驱动，由三块LED数码管构成的显示系统，与传统的基于8/16位普通单片机的LED显示系统相比较，本系统在不显著地增加系统成本的情况下，可支持更多的LED数码管稳定显示。设计采用AT98C51单片机，使用5V电源供电，并且在按键的作用下可以进行调时，调分，复位功能。计时数据的更新在计算机C语言的驱动下每秒自动进行一次，但不需程序干预其输出状态。

Abstract: The design of LED digital electronic control circuit with the 24-hour clock system in mind when they approach the design of the expansion AT89C51 single chip and chipset PNP transistor 6 so driven by the three LED digital display system consisting of control , And based on the traditional 8 / 16 of an ordinary single-chip LED display system compared to the present system does not significantly increase the cost of the system, can support more stable LED digital tube display. AT98C51 single chip design, the use of 5V power supply, and the key role can be carried out when the transfer, transfer points and reset functions. Time to update the data in the computer language C driven by a second automatic, but the procedures do not interfere with the state of the output..
