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，根据ADC0832集成IC进行AD转换，模拟输入转换过程信息，在LCD1602显示屏上显示，并且进行监视，当达到预设值时，将发出警报。此外，DS18B20温度传感器还用于监控温度。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 a circuit designed to maintain a refrigerator. This design uses the power supply circuit of the intelligent system. The system uses the mICrocontroller to protect the power supply circuit of the equipment. Mainly over voltage, under voltage maintenance, over current and weak current maintenance and temperature measurement maintenance, choose AT89C51 mICrocontroller to run the integrated IC, according to the ADC0832 integrated IC for AD conversion, analog input conversion process information, displayed on the LCD1602 display, and monitoring, when reached the preset value, will issue an alarm. In addition, the DS18B20 temperature sensor is used for temperature monitoring. When the temperature is not ideal, the power alarm will be turned off, and the maintenance of the power circuit will be disconnected, select the relay control loop.
