Abstract
This study aims to design an intelligent safety helmet to enhance the safety of workers in the workplace. The safety helmet is based on the STM32F103C8T6 microcontroller and incorporates various sensors and communication modules, providing multiple functionalities.Firstly, the DHT11 sensor is used to detect the ambient temperature and humidity. When the temperature and humidity exceed the preset limits, the system triggers an audio-visual alarm to remind the wearer to take necessary protective measures. Secondly, the SGP30 sensor is employed to monitor the CO2 concentration. If the CO2 concentration exceeds the predefined maximum value, the system emits an audio-visual alarm, alerting the wearer to leave the area with high levels of harmful gases. Thirdly, the MQ-135 sensor is utilized to detect harmful gas concentrations. When the concentration of harmful gases surpasses the set maximum value, the system generates an audio-visual alarm to protect the wearer’s health.Moreover, the system utilizes a photosensitive resistor to measure the ambient light intensity. When the light intensity falls below the specified minimum value, the system automatically turns on the lighting system, while also providing a manual option to control the lighting. The GPS module is employed to acquire the wearer’s latitude and longitude information, and the system allows the wearer to send their location information with a single button press for quick localization.The system also offers the functionality to set various thresholds using buttons, allowing the wearer to customize settings based on specific requirements. Additionally, measurement data is displayed on an OLED screen, enabling the wearer to easily comprehend environmental parameters. The data is transmitted to a smartphone via a 4G module, where thresholds can be set and location information can be obtained with a single button press, providing a convenient remote monitoring and management solution.
By integrating multiple sensors and communication technologies, the intelligent safety helmet effectively monitors environmental parameters and issues timely alarms, offering comprehensive safety protection measures. The development and application of this system hold significant practical significance and are expected to find extensive use in industrial sectors.
Key words: intelligent safety helmet, microcontroller, sensors, audio-visual alarm, location information, 4G communication.
