一种基于STC89C52单片机的智能闹钟的设计

The design of an intelligent alarm clock based on STC89C52 micro controller core

以STC89C52单片机为握力闹钟的控制核心,采用单片机定时器作为闹钟的时钟系统,由两块74HC595CMOS八移位寄存器控制八位数码管对时、分、秒,年、月、日及计数状态功能的显示。采用充电锂电池作为整个系统的供电电源。握力器作为运动机械,握力器的张合触发信号通过按键送入单片机,单片机通过计数值来做出是否停止响铃的判断,高效而人性化地将人们唤醒。

The design is based on STC89C52 micro contrelier core of the control of the alarm c）ock, Display module usfng 74HC595 which eight shift register to control eight digital tubes to display the Hour, minute, second, day, month, year and counting function, Using rechargeable lithium batteries as the entire system for power supply. Grip act as sports equipment and the grip trigger signal passed to the micro controller buy a key. The micro controller to make judgments by the count value and then control the alarm clock to stop ringing the bell, efficient and humanized wakes people up.
