多功能工业定时器设计

The Design of Multi-Purpose Industrial Tinner Warning System

主要设计了以STC89C51单片机为核心的多功能工业定时器设计,并且使用了万年历芯片DS1302、液晶显示器TS1620、蜂鸣器等器件。该设计采用C语言编程,包括液晶显示程序、万年历程序、按键扫描程序。该工业定时器应能够实现绝对时间和相对时间的定时,定时范围广,并且有信号输出。

This paper mainly designs a multi-purpose industrial timer which is based on STC89C5 l.The multi-purpose industrial timer uses the calendar chip DS1302, LCD TS1620, buzzers and other devices. The design uses C language programming, inchiding liquid crystal display program, calendar program, key scanner. The industrial timer should be able to achieve absolute time and timing of relative time wide range of timing, and a signal output.
