基于单片机的冰箱温度智能控制系统的设计 摘要：近年来随着计算机在社会领域的渗透, 单片机的应用正在不断地走向深入，同时带动传统控制检测日新月益更新。在实时检测和自动控制的单片机应用系统中，单片机往往是作为一个核心部件来使用，仅单片机方面知识是不够的，还应根据具体硬件结构，以及针对具体应用对象特点的软件结合，以作完善。 电冰箱温度控制系统是利用温度传感器DS18B20采集电冰箱冷藏室和冷冻室的温度，通过INTEL公司的高效微控制器MCS-C51单片机进行数字信号处理，从而达到智能控制的目的。本系统可实现电冰箱冷藏室和冷冻室的温度设置、电冰箱自动除霜、开门报警等功能。 本文在第一章介绍了电冰箱的系统组成及工作原理，第二章论述了本控制系统的硬件设计部分。第三章论述了系统的软件设计部分。 通过对直冷式电冰箱制冷系统的改进和采用模糊控制技术，实现了电冰箱的双温双控，使电冰箱能根据使用条件的变化迅速合理地调节制冷量，且节能效果良好。Abstract:?With the infiltration in the social field of the computer in recent years, the application of the one-chip computer is moving towards deepening constantly, drive tradition is it measure crescent benefit to upgrade day to control at the same time. In measuring in real time and automatically controlled one-chip computer application system, the one-chip computer often uses as a key part, only one-chip computer respect knowledge is not enough, should also follow the structure of the concrete hardware , and direct against and use the software of targets characteristic to combine concretly, in order to do perfectly. The electric refrigerator temperature control system is uses the temperature sensor DS18B20 gathering electric refrigerator cold-storageroom and the freezing room temperature, monolithic integrated circuit carries on the digital signal processing through INTEL Corporations highly effective micro controller MCS-C51, thus achieves the intelligent control the goal. This system may realize the electric refrigerator cold-storageroom and the freezing room temperature establishment, the electric refrigerator automatically defrosts, opens the gate to report to the police and so on the function. This article introduced in the first chapter the electric refrigerator system composition 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 vague-control technology, the goal of
