In measuring in real time and automatically controlled onechip puter application system, the onechip puter often uses as a key part, only onechip puter respect knowledge is not enough, should also follow the structure of the concrete hardware , and direct against and use the software of target39。s characteristic to bine concretly, in order to do perfectly The electric refrigerator temperature control system is uses the temperature sensor DS18B20 gathering electric refrigerator coldstorageroom and the freezing room temperatureWith evaporating surface temperature monolithic integrated circuit carries on the digital signal processing through INTEL corporation?s highly effective micro controller MCSC51 ,thus achieves the intelligent control the goal .This system may realize the electric refrigerator coldstorageroom and the freezing room temperature establishment , The electric refrigerator automatically defrosts ,opens the gate to rapot to the police and so on the function This article introduced in the first chapter the electric refrigerator system position and the principle of work, the second chapter elaborated this control system hardware design part. Third chapter elaborated the system software design part. By improving the refrigerating system of refrigerator and applying the vaguecontrol technology, the goal of doubletemperature, doublecontrol has been realized。it makes possible for the refrigerator to regulate the amount of cold air in a speedy and rational way. Thus, power saving is available Key words： The onechip puter； The temperature sensor； The electric refrigerator； Temperature control 更多論文 4 目錄 第一章 緒論 ................................................................................................................................................................. 6 電冰箱的結(jié)構(gòu)和工作原理 ............................................................................................................................... 6 1 .2 智能冰箱控制器的實現(xiàn)功能 .......................................................................................................................... 6 家用電冰箱的發(fā)展趨勢 ................................................................................................................................... 7 第二章 智能冰箱控制器系統(tǒng)硬件設(shè)計 ................................................................................................................... 9 系統(tǒng)硬件方案設(shè)計 ........................................................................................................................................... 9 硬件電路主要組成 ......................................................................................................................................... 10 MCS51單片機(jī)硬件介紹 ..................................................................................................................... 10 MCS51單片機(jī)中央處理器 ................................................................................................................. 10 MCS51單片機(jī)存儲器 ......................................................................................................................... 10 MCS51單片機(jī)中斷系統(tǒng) ..................................................................................................................... 11 MCS51單片機(jī)引腳介紹 ..................................................................................................................... 11 單片機(jī)的時鐘及復(fù)位 ............................................................................................................................ 13 時鐘電路 ................................................................................................................................................. 13 基本時序單位 ......................................................................................................................................... 14 復(fù)位電路 ................................................................................................................................................. 14 單片機(jī)應(yīng)用 ............................................................................................................................................. 16 智能冰箱控制器中使用 89C51 單片機(jī)的說明 .................................................................................. 17 溫度傳感器 DS18B20 .................................................................................................................................... 18 DS18B20 的外形和內(nèi)部結(jié)構(gòu) ............................................................................................................... 18 DS18B20 的供電方式選擇 ................................................................................................................... 21 智能冰箱控制器中采用 DS18B20的論證 ......................................................................................... 23 外圍電路設(shè)計 ..................................
