摘要
在现代工厂生产中，生产线环境参数的稳定与生产效率的把控是保障产品质量和生产效益的关键。温湿度异常可能导致设备故障或产品质量下降，生产速度的波动则直接影响生产计划的执行，这些问题若不能及时监测和干预，可能给企业带来经济损失。因此，研发一种能实时、精准监控生产线环境与生产状态的系统十分必要。
本设计提出一种基于 STM32F103C8T6 单片机的物联网工厂生产线监控系统。系统主要功能包括：通过DHT11 传感器检测当前生产环境的温湿度，当温度或湿度大于最大值时进行声光报警；借助HWFS 分离式红外对射管检测物品生产数量，结合时间计算生产速度，速度大于最大值或小于最小值时触发声光报警；用户通过按键设置温湿度最大值、速度极值及开启 / 关闭生产监控；通过OLED 显示屏实时显示温湿度、生产数量、速度及监控状态；同时，系统通过WiFi 模块将检测数据传输至手机端，手机可远程设置各项参数及控制监控开关。
该系统的作用在于，为工厂提供了一种智能化的生产线监控方案。通过实时监测、自动报警和远程控制，能够帮助企业及时发现生产异常，优化生产流程，保障生产稳定运行，提升生产管理效率与效益。

Design of Factory Production Line Monitoring System Based on Internet of Things
Abstract
In modern factory production, the stability of production line environmental parameters and the control of production efficiency are key to ensuring product quality and production efficiency. Abnormal temperature and humidity may lead to equipment failure or decreased product quality, and fluctuations in production speed directly affect the execution of production plans. If these issues are not monitored and intervened in a timely manner, they may cause economic losses to the enterprise. Therefore, it is necessary to develop a system that can monitor the production line environment and production status in real-time and accurately.
This design proposes an IoT factory production line monitoring system based on STM32F103C8T6 microcontroller. The main functions of the system include: detecting the temperature and humidity of the current production environment through DHT11 sensors, and issuing sound and light alarms when the temperature or humidity exceeds the maximum value; Using HWFS separated infrared tube to detect the production quantity of items, combined with time calculation of production speed, triggering sound and light alarms when the speed is greater than the maximum value or less than the minimum value; Users can set the maximum temperature and humidity values, speed limits, and turn on/off production monitoring through buttons; Real time display of temperature and humidity, production quantity, speed, and monitoring status through OLED display screen; At the same time, the system transmits the detection data to the mobile phone through the WiFi module, and the mobile phone can remotely set various parameters and control the monitoring switch.
The function of this system is to provide an intelligent production line monitoring solution for factories. Through real-time monitoring, automatic alarm and remote control, it can help enterprises detect production abnormalities in a timely manner, optimize production processes, ensure stable production operation, and improve production management efficiency and benefits.
