摘要
在现代家庭生活中，压力锅作为高效便捷的烹饪工具，其安全性与智能化水平备受关注。传统压力锅多依赖手动操作，存在温度和压力控制精度不足、模式单一、缺乏实时监测与远程控制等问题，难以满足用户对精准烹饪和便捷操作的需求。
基于 STM32F103C8T6 单片机的压力锅设计，整合了 DS18B20 防水式温度检测模块、XGZP6847 压力检测模块、YW-J 水位监测模块、3 个独立按键、OLED 显示屏、ESP8266WiFi 模块及加热装置、声光报警装置等，实现了压力锅的自动化烹饪、安全监测与智能控制。系统核心功能包括：通过 DS18B20 实时监测锅内温度，精准把控烹饪火候；借助 XGZP6847 检测压力，当压力超过设定最大值时，立即触发声光报警并停止加热，保障使用安全；通过按键切换煮饭、煮粥、煲汤、炖肉等模式，不同模式对应不同烹饪时间，启动后自动加热，达到设定温度后停止；利用 YW-J 模块监测水位，避免干烧风险；支持按键设置温度值、切换模式及控制启停；通过 OLED 显示屏实时显示温度、压力、水位、当前模式及剩余时间等信息；借助 ESP8266WiFi 模块将数据传输至手机端，支持手机端选择模式、控制启停及查看烹饪状态。
该设计的实现，有效提升了压力锅的安全性、智能化与便捷性，解决了传统压力锅操作繁琐、控制精度低的问题，为用户提供了精准、安全、高效的烹饪体验，同时为厨房电器的智能化升级提供了参考，具有较高的实际应用价值。

ABSTRACT
In modern family life, pressure cookers, as efficient and convenient cooking tools, have attracted much attention for their safety and intelligence. Traditional pressure cookers mostly rely on manual operation, with problems such as insufficient precision in temperature and pressure control, single mode, lack of real-time monitoring and remote control, making it difficult to meet users’ needs for precise cooking and convenient operation.
The pressure cooker design based on the STM32F103C8T6 microcontroller integrates DS18B20 waterproof temperature detection module, XGZP6847 pressure detection module, YW-J water level monitoring module, 3 independent buttons, OLED display, ESP8266WiFi module, heating device, sound and light alarm device, etc., realizing automatic cooking, safety monitoring and intelligent control of the pressure cooker. The core functions of the system include: real-time monitoring of the temperature inside the pot through DS18B20 to accurately control the cooking heat; detecting pressure with XGZP6847, and when the pressure exceeds the set maximum value, immediately triggering an audible and visual alarm and stopping heating to ensure safety in use; switching modes such as rice cooking, porridge cooking, soup making, and meat stewing through buttons, with different modes corresponding to different cooking times, automatically heating after startup, and stopping when the set temperature is reached; using YW-J module to monitor water level to avoid the risk of dry burning; supporting button setting of temperature value, mode switching and start-stop control; real-time display of temperature, pressure, water level, current mode and remaining time through OLED display; transmitting data to the mobile phone through ESP8266WiFi module, supporting mobile phone selection of modes, control of start-stop and viewing of cooking status.
The implementation of this design effectively improves the safety, intelligence and convenience of the pressure cooker, solves the problems of cumbersome operation and low control precision of traditional pressure cookers, provides users with a precise, safe and efficient cooking experience, and also provides a reference for the intelligent upgrading of kitchen appliances, with high practical application value.
