2、TC89C52RC 的定时器与中断设计一段时间的倒计时，当倒计时到了预设的时 间继电器就会接通，相应的电器就会开始工作，时间结束继电器关闭，电器也停止工 作。本设计通过程序的循环设计可以实现倒计时的无限重复，即第一次倒计时结束后 会自动复位，继续下一轮的倒计时，所以一旦开始工作，无需人为的其他任何操作就 可以实现时间无限制的循环工作，真正实现智能、定时。 关键词： STC89C52RC，定时器，数码管，继电器 II A Design Of Smart Timing Power Switch Abstract With the increasingly popularity of the hou
