摘 要

    隨著電子技術(shù)的迅速發(fā)展，特別是隨大規(guī)模集成電路出現(xiàn)，給人類生活帶來了根本性的改變。由其是單片機(jī)技術(shù)的應(yīng)用產(chǎn)品已經(jīng)走進(jìn)了千家萬戶。電子萬年歷的出現(xiàn)給人們的生活帶來的諸多方便。
本文首先描述系統(tǒng)硬件工作原理，并附以系統(tǒng)結(jié)構(gòu)框圖加以說明，著重介紹了本系統(tǒng)所應(yīng)用的各硬件接口技術(shù)和各個(gè)接口模塊的功能及工作過程,其次，詳細(xì)闡述了程序的各個(gè)模塊和實(shí)現(xiàn)過程。本設(shè)計(jì)以數(shù)字集成電路技術(shù)為基礎(chǔ)，單片機(jī)技術(shù)為核心。本文編寫的主導(dǎo)思想是軟硬件相結(jié)合，以硬件為基礎(chǔ)，來進(jìn)行各功能模塊的編寫。
本系統(tǒng)以單片機(jī)的C語言進(jìn)行軟件設(shè)計(jì)，增加了程序的可讀性和可移植性,為了便于擴(kuò)展和更改，軟件的設(shè)計(jì)采用模塊化結(jié)構(gòu)，使程序設(shè)計(jì)的邏輯關(guān)系更加簡(jiǎn)潔明了。系統(tǒng)通過點(diǎn)陣式液晶為載體顯示數(shù)據(jù)，所以具有人性化的操作和美觀的頁(yè)面效果?？梢燥@示年月日、星期、溫度等

Title    Electronic real-time clock/ Calendar system                   
       
Abstract
Along with the rapid development of electronic technology, especially with large scale integrated circuit appear, give mankind living has brought the fundamental change. By its is the application of single-chip computer technology product has entered innumberable families. Electronic calendar appear to the life of people bring many convenient.
This paper firstly describes the system hardware working principle, each accompanied by a diagram of the system structure of the elucidation, introduces this system by the application of the hardware interface technology and the function of each interface module and the working process, and secondly, expounded the program modules and realization process. This design with digital integrated circuit technology as the foundation, microcontroller technology as the core. In this paper the compiling principle is combining software with hardware, based on the preparation of the functional modules.
The system takes microcontroller C language software design, increased the readability of our programs and portability, to facilitate the expansion and change, the design of software modular structure, make the program design of logical relationship more concise. System through dot-matrix LCD display data for carrier, so has the humanized operate and beautiful page effect. Can display the time, and lunar dates, week, temperature, solar term, tian gan earthly branches and the day sunrise sunset time, and has alarm and intelligent control household appliances function.
