摘要
随着工业生产与科研实验对环境温度监测要求的不断提高，多点温度的精准、同步检测对保障设备正常运行、实验数据可靠性具有重要意义。传统的单点温度检测方式不仅效率低下、难以实现多区域同步监测，还依赖人工记录与判断，存在响应滞后、误差较大等问题，难以满足规模化、智能化场景的需求。
基于 STM32F103C8T6 单片机的多点温度巡回检测系统，整合了四个 DS18B20 温度监测模块、按键、OLED 显示屏、声光报警装置及 WiFi 模块，实现了多区域温度的自动化监测与智能预警。系统核心功能包括：通过四个 DS18B20 模块分别监测不同区域的温度，实时获取各点温度值；支持通过按键设置温度的最大值和最小值，当任一区域温度大于最大值或小于最小值时，触发声光报警；OLED 显示屏实时显示四个监测点的温度数据及报警状态；借助 WiFi 模块将温度数据传输至手机端，手机端也可远程设置温度的最大、最小值。
该系统的实现，有效提升了多点温度监测的自动化与智能化水平，减少了人工干预，确保了温度监测的及时性与准确性，为工业生产、科研实验等场景提供了高效、可靠的温度监测解决方案，同时为同类多点监测设备的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
With the increasing requirements for environmental temperature monitoring in industrial production and scientific research experiments, accurate and synchronous detection of multi-point temperatures is of great significance for ensuring the normal operation of equipment and the reliability of experimental data. The traditional single-point temperature detection method is not only inefficient and difficult to achieve synchronous monitoring of multiple areas, but also relies on manual recording and judgment, with problems such as delayed response and large errors, which is difficult to meet the needs of large-scale and intelligent scenarios.
The multi-point temperature 巡回 detection system based on STM32F103C8T6 microcontroller integrates four DS18B20 temperature monitoring modules, buttons, OLED display, sound and light alarm device and WiFi module, realizing automatic monitoring and intelligent early warning of multi-area temperatures. The core functions of the system include: real-time temperature values of each point are obtained through four DS18B20 modules monitoring temperatures in different areas respectively; it supports setting the maximum and minimum temperature values through buttons, and triggers sound and light alarm when the temperature in any area is higher than the maximum value or lower than the minimum value; the OLED display real-time shows the temperature data and alarm status of the four monitoring points; the temperature data is transmitted to the mobile phone through the WiFi module, and the mobile phone can also remotely set the maximum and minimum temperature values.
The implementation of this system effectively improves the automation and intelligence level of multi-point temperature monitoring, reduces manual intervention, ensures the timeliness and accuracy of temperature monitoring, provides an efficient and reliable temperature monitoring solution for industrial production, scientific research experiments and other scenarios, and also provides a reference for the research and development of similar multi-point monitoring equipment, with high practical application value.
