"智能化电饭锅电子保姆仪的设计与实现"

The design and implementation of the rice cooker electronic nanny instrument based on single-chip microcomputer are the focus of this thesis. This electronic nanny instrument represents a new generation of intelligent rice cookers, incorporating advanced features such as timed water filling and cooking functions, while inheriting the advantages of traditional rice cookers. The system is designed to start cooking at a specified time and automatically stop working when the rice is cooked within a specified time. The design utilizes a temperature sensor DS18B20 to collect temperature data, and controls the relay off through the low voltage output of the single-chip microcomputer, achieving the effect of shutting off the water inlet valve and disconnecting the automatic circuit. Additionally, it has a display function that shows the working status on the LCD screen over time. The entire process is controlled by the single-chip microcomputer. This article introduces a new type of rice cooker control system, detailing the overall design concept, hardware design, and software system. It also provides a detailed introduction to the functions and implementation of the system, as well as potential shortcomings and improvements for the design. Keywords: single-chip control; timing function; relay control; sensor.
