摘要
随着工业生产、智能家居等领域对环境温湿度控制精度与智能化需求的不断提升，传统单一路径或手动控制的温湿度调节方式已难以满足多区域、高精度、自动化管理的复杂要求。在实际应用中，温湿度监测点单一导致的数据片面性、人工干预滞后引发的环境波动、以及多设备协同控制不便等问题日益突出，亟需构建一套集成化、智能化的温湿度控制系统。本设计以STM32F103C8T6单片机为核心，通过模块化硬件架构与高效软件算法，开发出具备八路监测与智能调控功能的温湿度控制系统。
硬件层面，系统采用八个DHT11温湿度传感器实现对不同区域环境参数的实时采集，配合按键模块实现对特定监测通道的灵活选择与功能模式切换；集成OLED显示屏用于本地数据可视化与参数设置，通过蓝牙模块实现与手机端的数据交互与远程控制；同时，系统配置了加热、制冷、加湿、除湿等执行机构及声光报警装置，确保在环境参数异常时能及时响应。软件方面，基于单片机的多任务处理能力，设计了数据采集、平均温湿度计算、阈值判断、设备联动控制及人机交互等核心算法。系统能够根据用户设定的温湿度上下限值，对已启动的传感器监测数据进行平均运算，当均值超出设定范围时，自动触发相应的调节执行器，并启动声光报警；同时支持通过按键手动控制各执行机构的启停及模式切换，以及通过手机蓝牙端进行远程数据查看与设备操控。
该八路温湿度控制系统的成功开发与调试，有效克服了传统温湿度控制方式的局限性，显著提升了环境监测的全面性、控制的精准性与操作的便捷性。系统八路监测功能可实现多区域环境的同步感知，平均温湿度计算确保了调控依据的科学性；自动与手动双重控制模式兼顾了智能化与应急操作需求；本地与远程数据交互提升了系统的易用性与管理效率。本设计为多区域环境温湿度的智能化管理提供了切实可行的解决方案，对提高生产生活环境质量、降低人工管理成本具有重要意义，拥有广阔的应用前景与推广价值。

ABSTRACT
With the continuous improvement of requirements for precision and intelligence in environmental temperature and humidity control in fields such as industrial production and smart homes, traditional temperature and humidity regulation methods with single-path or manual control have been difficult to meet the complex demands of multi-area, high-precision, and automated management. In practical applications, problems such as data one-sidedness caused by single temperature and humidity monitoring points, environmental fluctuations due to delayed manual intervention, and inconvenience in collaborative control of multiple devices have become increasingly prominent, making it urgent to construct an integrated and intelligent temperature and humidity control system. This design takes the STM32F103C8T6 microcontroller as the core and develops a temperature and humidity control system with eight-channel monitoring and intelligent regulation functions through a modular hardware architecture and efficient software algorithms.
At the hardware level, the system uses eight DHT11 temperature and humidity sensors to achieve real-time collection of environmental parameters in different areas, and cooperates with a key module to realize flexible selection of specific monitoring channels and function mode switching; an integrated OLED display is used for local data visualization and parameter setting, and a Bluetooth module is used to realize data interaction and remote control with the mobile phone; at the same time, the system is equipped with heating, refrigeration, humidification, dehumidification and other actuators as well as sound and light alarm devices to ensure timely response when environmental parameters are abnormal. In terms of software, based on the multi-tasking processing capability of the microcontroller, core algorithms such as data collection, average temperature and humidity calculation, threshold judgment, equipment linkage control, and human-computer interaction are designed. The system can perform average calculation on the monitoring data of activated sensors according to the user-set upper and lower limits of temperature and humidity. When the average value exceeds the set range, it automatically triggers the corresponding regulating actuator and activates the sound and light alarm; it also supports manual control of the start/stop and mode switching of each actuator through buttons, as well as remote data viewing and equipment control through the mobile phone Bluetooth terminal.
The successful development and debugging of this eight-channel temperature and humidity control system have effectively overcome the limitations of traditional temperature and humidity control methods and significantly improved the comprehensiveness of environmental monitoring, the precision of control, and the convenience of operation. The eight-channel monitoring function of the system can realize synchronous perception of multi-area environments, and the calculation of average temperature and humidity ensures the scientificity of the regulation basis; the automatic and manual dual control modes take into account the needs of intelligence and emergency operations; local and remote data interaction improves the usability and management efficiency of the system. This design provides a practical solution for the intelligent management of temperature and humidity in multi-area environments, is of great significance for improving the quality of production and living environments and reducing manual management costs, and has broad application prospects and promotion value.
