In the scenario of large-scale smart factory management and control, factory personnel intrusion, door and window opening and closing status, and environmental temperature and humidity parameters are core indicators to ensure factory production safety, stable equipment operation and standard environmental management. The traditional manual inspection and management mode of factories has defects such as poor real-time monitoring, lagging security early warning, slow response of environmental regulation, high manual operation and maintenance costs, and inability to realize all-weather intelligent management. The manual inspection-based management method cannot meet the automatic and refined management requirements of modern smart factories. This paper proposes a design and implementation scheme of a smart factory based on STM32F103C8T6 microcontroller and IoT cloud platform. The system integrates core functions including human infrared security detection, door and window status monitoring, automatic environmental temperature and humidity regulation, local human-computer interaction, remote video monitoring, WiFi wireless data transmission, custom parameter thresholds, cloud data synchronization and remote control. The D203S human pyroelectric sensor is used to real-time detect the activity status of factory personnel, and the KY-003 Hall sensor is adopted to monitor the opening and closing status of factory doors and windows in real time. When abnormal intrusion and door or window opening actions are detected under the system arming state, local sound and light alarms will be triggered immediately, and pop-up window and vibration early warnings will be synchronized on the mobile terminal. The DHT11 temperature and humidity detection module collects real-time environmental temperature and humidity data of the factory, and automatically compares the monitored data with the user-preset temperature thresholds to realize intelligent temperature regulation. The fan is automatically started for cooling at high temperatures, and the relay module is linked to turn on the heating sheet and fan to realize hot air heating at low temperatures, ensuring a constant factory environmental temperature. Equipped with independent keys, the system supports arming and disarming switching, custom setting of temperature thresholds, and manual control of fans and heating equipment. The OLED display screen locally displays the equipment arming status, factory temperature and humidity data, door and window switching status and on-site personnel monitoring status in real time. Meanwhile, the camera module realizes remote viewing of real-time factory on-site pictures and playback of historical pictures. The ESP8266 WiFi communication module uploads real-time on-site monitoring data and equipment operating status to the IoT cloud platform for data cloud synchronization. The mobile terminal can receive equipment data in real time, remotely switch arming and disarming modes, modify temperature and humidity regulation thresholds, and manually control the start and stop of fans and heating equipment. This system effectively solves the pain points of low efficiency of manual inspection and management, untimely security early warning, low intelligence of environmental regulation and inconvenient remote management in traditional factories. It realizes the all-weather automatic operation and remote visual management of security monitoring, environmental regulation and equipment control of smart factories, greatly improves the intelligent and refined management level of factories, and has excellent industrial application value and promotion prospects.
