Multi-function, intelligent is one of its development direction, the traditional machine control, simple electronic control has been difficult to meet the requirements of the development. MCU is the center of real-time detection and control system a core device. This design of microcontroller-based temperature control system is used refrigerator temperature sensor DS18B20 collecting refrigerator freezer temperature, high-performance companies through INTEL microcontroller MCS-51 MCU signal control so as to achieve intelligent control. The system can set the refrigerator temperature, refrigerators over voltage detection, open display, open the compressor delay functions. Through direct cool refrigerator cooling system improvements, implementation of the intelligent control of refrigerator to refrigerator according to rapidly changing conditions of reasonable use to adjust cooling, and the effect is good. key word：MCU; refrigerator; temperature control; over-voltage detection 青岛理工大学毕业论文 PAGE II 青岛理工大学毕业论文 PAGE \* MERGEFORMAT I 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc327277041 前 言 PAGEREF _Toc327277041 \h 1 HYPERLINK \l _Toc327277044 第1章 绪 论 PAGEREF _Toc327277044 \h 2 HYPERLINK \l _Toc327277045 1.1 课题研究状况及目的 PAGEREF _Toc327277045 \h 2 HYPERLINK \l _Toc327277046 1.2 电冰箱的系统组成及工作原理 PAGEREF _Toc327277046 \h 3 HYPERLINK \l _Toc327277047 1.3 本设计研究内容 PAGEREF _Toc327277047
