AI Technical Summary

Technical Problem

Existing alarm devices at construction sites often have limited alarm functionality in noisy environments, making it difficult to effectively attract the attention of personnel on site and significantly reducing their alarm effectiveness.

Method used

The system combines infrared sensors, motors, electric actuators, alarm lights, and loudspeakers to create a multi-mode alarm system that integrates sound and light. When an unauthorized intrusion is detected by the infrared sensor, the motor is activated to rotate the alarm light and the striking ball strikes the bell to generate an audible warning, ensuring the effective propagation of light and sound at the construction site.

Benefits of technology

It effectively alerts on-site personnel to unauthorized intrusions in noisy construction environments through a combination of sound and light, improving the visibility and coverage of the alarm and ensuring construction safety.
