Four-Function Fully Automatic Refrigerator Protection System Design

Abstract In the automatic refrigerator protection system hardware design, the MCU is selected as the core control of the system, the specific design content includes the selection of the automatic refrigerator protection system design scheme, MCU, and sensor types and models, in addition, it is necessary to combine the components of the display module design; In the system software design, the most core content is the system program design. The system collects the undervoltage, overvoltage, power failure, leakage, and other conditions of the power supply refrigerator, and the control switch is automatically disconnected to protect the refrigerator. C language was chosen to design the system software code, and Proteus software was used to realize the system function simulation, and the functions of the system were verified.
