摘要
随着医药行业的严格规范，药品生产车间的环境参数对药品质量与生产安全至关重要。传统车间环境监测依赖人工巡检和手动记录，存在数据滞后、调控不及时、误差较大等问题，难以满足药品生产的高标准要求。
基于 STM32F103C8T6 单片机的药品生产车间环境监测系统，整合了 5516 光照检测模块、DS18B20 温度传感器、GP2Y1014AU 粉尘检测模块、MQ-135 有害气体传感器、MQ-2 烟雾传感器、OLED 显示屏及按键，实现了对车间环境的实时监测与智能调控。系统核心功能包括：通过 5516 光照检测模块监测光照值，低于设定最小值时自动开启照明灯；借助 DS18B20 检测温度，高于设定最大值时自动启动空调降温；利用 GP2Y1014AU 检测粉尘浓度，超标时通过 ULN2003 驱动步进电机模拟打开窗户通风；通过 MQ-135 和 MQ-2 分别检测有害气体与烟雾值，超标时触发声光报警，烟雾超标时还会启动水泵灭火；支持通过按键设置各参数阈值；通过 OLED 显示屏实时展示各项监测数据。
该系统的实现，有效提升了药品生产车间环境监测的自动化与精准性，通过多参数实时监测与智能响应，为药品生产提供了安全、稳定的环境保障，同时为工业生产环境监测设备的研发提供了参考，具有较高的实用价值与行业意义。

ABSTRACT
With the strict regulations in the pharmaceutical industry, environmental parameters in pharmaceutical production workshops are crucial to drug quality and production safety. Traditional workshop environmental monitoring relies on manual inspections and manual records, which have problems such as delayed data, untimely regulation, and large errors, making it difficult to meet the high standards required for pharmaceutical production.
The environmental monitoring system for pharmaceutical production workshops based on the STM32F103C8T6 single-chip microcomputer integrates the 5516 light detection module, DS18B20 temperature sensor, GP2Y1014AU dust detection module, MQ-135 harmful gas sensor, MQ-2 smoke sensor, OLED display, and buttons, realizing real-time monitoring and intelligent regulation of the workshop environment. The core functions of the system include: monitoring the light intensity through the 5516 light detection module, and automatically turning on the lighting when the light intensity is lower than the set minimum value; detecting the temperature with the DS18B20, and automatically starting the air conditioner for cooling when the temperature is higher than the set maximum value; using the GP2Y1014AU to detect the dust concentration, and when it exceeds the standard, simulating opening windows for ventilation through the ULN2003-driven stepper motor; detecting harmful gas and smoke values through MQ-135 and MQ-2 respectively, triggering sound and light alarms when exceeding the standards, and starting the water pump for fire extinguishing when the smoke exceeds the standard; supporting the setting of various parameter thresholds through buttons; and displaying various monitoring data in real-time through the OLED display.
The implementation of this system has effectively improved the automation and accuracy of environmental monitoring in pharmaceutical production workshops. Through multi-parameter real-time monitoring and intelligent response, it provides a safe and stable environmental guarantee for pharmaceutical production. At the same time, it provides a reference for the research and development of industrial production environmental monitoring equipment, with high practical value and industry significance.
