1、电冰箱温度测控系统设计（A）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，同吋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,述应根据具体硕件结构，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采集电冰箱冷藏室的温度，通过Atmel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温度设置、电冰
2、箱过欠压检测、开门显示、压缩机开启延时等功能。通过对直冷式电冰箱制冷系统的改进，实现了电冰箱的温度智能控制，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。关键词：单片机；温度传感器；电冰箱；温度控制ElectricRefrigeratorTemperatureObservationandControlSystemDesign(A)Abstract:Withtheinfiltrationinthesocialfieldofthecomputerinrecentyears,thea
