Applying beacon sensor alarm system for construction worker safety in workplace

The construction site is one of the most dangerous workplaces among all the industries, workers are exposed to various hazards sources. Ubiquitous accidents occur even with detailed regulations and laws. Situation awareness theory revealed that there are three processes when people are dealing with the changing environment: perception of environmental situation, comprehension of what people are dealing with and decision-making. The likelihood of risky behaviours increases a lot when any of these processes go wrong. In this paper, the author proposed an alarm system to help workers get a better perception of construction site and improve the efficiency and quality of safety management. In this system, a beacon sensor will be deployed on the hazard source and it will keep send Bluetooth package to receiver equipment. Workers will carry the receiver, a BLE sensor, to calculate the distance between people and the hazard point. If the distance is less than the setting number, the sensor will trigger the alarm to broadcast siren and send the unsafety behaviour event to manager backend to archive the entire process.
