时钟芯片DS1302在校园电视信号控制系统中的应用

The Application of Clock Chip DS1302 in the Control System of Campus Television Signal

基于时钟芯片DS1302设计了用来控制校园电视信号定时传送的校园电视信号控制系统,可以方便地设置信号送出和中断的时间,便于校园电视信号控制的管理。文中详细给出了校园电视信号控制系统中DS1302芯片与AT89C51的接口电路设计以及整个系统的电路设计,以某大学校园电视信号的发送时间为例完成了系统运行软件的设计。

A set of campus television signal control system based on DS1302 clock chip is designed to transfer the campus television signal as desired. The system can be used to send out and interrupt the campus television signal, and manage the campus television signal broadcast conveniently. The interface circuit of DS1302 and AT89C51, and the system circuit are presented in this paper. At last, an example is given to descript the software design of the system.
