基于STC89C51的温测型多功能电子万年历设计

摘要

本文介绍了基于STC89C51单片机的多功能电子万年历的硬件结构和软硬件设计方法。本设计由数据显示模块、温度采集模块、时间处理模块和调整设置模块4部分组成。系统以STC89C51单片机为主控芯片；以串行时钟日历芯片DS1302作为时间信号源，可以完成对年、月、日、等进行计时的任务；选用DS18B20数字温度传感器进行温度采集。采用1602液晶显示模块可同时显示年、月、日等及温度信息。此万年历结合测温功能具有功能多样、电路简洁、成本低廉等诸多优点，具有广阔的市场前景。%This paper introduces the hardware structure and the software design method of the electronic calendar based on STC89C51 single-chip microcomputer. This design made up of four modules: the data display module, temperature acquisition module, time processing module and the settings module. This system use STC89C51 single-chip microcomputer as the controler, serial clock chip DS1302 to record the time, it can be for years, months, days, hours and etc. With DS18B20 temperature acquisition, the display unit(LCD1602) can show temperature at the same time. The functional is diversity, it has a broad market prospect.
