【正文】 論文題目： 基于 單片機定時控制器的研制 摘 要 隨著電子技術的迅速發(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。由其是單片機技術的應用產品已經(jīng)走進了千家萬戶。 作為單片機技術應用之一的定時控制器，在日常生活，工業(yè)場合甚至軍事領域都有應用。 本 文主要介紹了單片機定時控制器的硬件設計過程。單片機作為主控器件，是整個系統(tǒng)的核心，它起到主要的控制作用；時鐘芯片為系統(tǒng)提供一個數(shù)字鐘，定時功能的實現(xiàn)也要依賴它；液晶模塊為系統(tǒng)顯示提供載體；按鍵部分采用獨立式結構，主要用作調時和定時，也可用作功能選擇； 控制輸出部分通過繼電器的動作和發(fā)光二極管的亮滅，模擬機器的開和停。 本文完成了對系統(tǒng)硬件電路制作、軟件設計和調試過程的說明，系統(tǒng)最終實現(xiàn)分時段定時控制的功能。 關鍵詞 ： 單片機，時鐘芯片，液晶模塊，定時控制 Subject： Development of Time Controller Based on Single Chip Microprocessor ABSTRACT Along with the electronic technology rapid development, appears of the large scale integrated circuit specially, these have made a big change on people’s living. Products including the technology application of the single chip microprocessor sets already entered every family. As one application of the single chip microprocessor technology, the time controller has been applied in the daily life, the industry situation and military field. This article introduced mainly the design process of the time controller posed by the single chip microprocessor. As the main control ponent, the single chip microprocessor is the core of the device and it plays the main control action. The clock chip provides a digital clock for the device and helps to realize the function of the timing control. The liquid crystal display is the carrier for the device system demonstrating. The keys use free standing structure. They mainly use as the timing and fixed time and use also as function choice. The control output simulates machine39。s opening and stops by relay39。s movement and the light emitter diode. This article has showed the process of the hardware manufacture, the software design and debugging. The function of the time controller is realized finally.
