人類最早使用的定時(shí)工具是沙漏或水漏，但在鐘表誕生發(fā)展成熟之后，人們開(kāi)始嘗試使用這種全新的計(jì)時(shí)工具來(lái)改進(jìn)定時(shí)器，達(dá)到準(zhǔn) 確控制時(shí)間的目的。單片機(jī)作為主控器件，是整個(gè)系統(tǒng)的核心，它起到主要的控制作用；時(shí)鐘芯片為系統(tǒng)提供一個(gè)數(shù)字鐘，定時(shí)功能的實(shí)現(xiàn)也要依賴它；液晶模塊為系統(tǒng)顯示提供載體；按鍵部分采用獨(dú)立式結(jié)構(gòu)，主要用作調(diào)時(shí)和定時(shí)，也可用作功能選擇； 控制輸出部分通過(guò)繼電器的動(dòng)作和發(fā)光二極管的亮滅，模擬機(jī)器的開(kāi)和停。論文題目： 基于 單片機(jī)定時(shí)控制器的研制 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(lái)了根本性的改變。 本 文主要介紹了單片機(jī)定時(shí)控制器的硬件設(shè)計(jì)過(guò)程。s opening and stops by relay39。起初每周上一次發(fā)條， 1918 年使用電鐘計(jì)時(shí)后，就不用上發(fā)條了。 目前單片機(jī)滲透到 日常 生活的各個(gè)領(lǐng)域，幾乎很難找到哪個(gè)領(lǐng)域沒(méi)有單片機(jī)的蹤跡。 為了能夠鞏固以前所學(xué)習(xí)的單片機(jī)原理的有關(guān)知識(shí)，并將其應(yīng)用到實(shí)踐中，培養(yǎng)動(dòng)手能力和解決實(shí)際問(wèn)題的能力， 因此選擇了基于單片機(jī)的定時(shí)控制器的設(shè)計(jì)課題。 單片機(jī) STC89C58RD+結(jié)構(gòu) STC89C58RD+是宏
