基于STC89C52的电冰箱保护器控制系统设计
摘要
本文是维护电冰箱所设计的电路。本设计方案使用了智能系统的电源电路，该系统使用微控制器来保护设备的电源电路。主要是过电压、欠电压的维护，过电流和弱电流的维护以及冰箱线路温度测量维护等，选择STC89C52单片机运行集成IC，通过两个防水式DS18B20测量冰箱的上下层温度，并通过两个继电器模拟上下层制冷系统，当温度高于设置最大值时，相应层的继电器闭合进行制冷，直到小于设置最小值。当线路温度，冰箱电压、电流不理想时，将关闭电源警报，并断开对电源电路的维护，也可以通过按键控制冰箱的开关。

Abstract
This paper is designed to maintain the circuit of the refrigerator. This design scheme uses the power circuit of the intelligent system, which uses a microcontroller to protect the power circuit of the device. It mainly includes maintenance of overvoltage and undervoltage, maintenance of overcurrent and weak current, and measurement and maintenance of refrigerator line temperature. The STC89C52 single chip computer is selected to run the integrated IC, measure the temperature of the upper and lower layers of the refrigerator through two waterproof DS18B20, and simulate the upper and lower layers of the refrigeration system through two relays. When the temperature is higher than the set maximum value, the relay of the corresponding layer is closed for refrigeration until it is less than the set minimum value. When the line temperature, refrigerator voltage and current are not ideal, the power alarm will be turned off, and the maintenance of the power circuit will be disconnected. You can also control the switch of the refrigerator by pressing a key.
Keywords:SCM; call the police; Temperature sensing; Refrigerator.
