Development of a mobile safety monitoring system for construction sites

In spite of efforts to reduce fatal accidents on construction sites, such accidents continue to occur. In particular, fall accidents constitute the majority of these accidents, and therefore appropriate managing measures are needed. In this study, a safety monitoring system was established at a site where fall accidents often occurred, with the aim of reducing the rate of fatal accidents on the construction site. The system consisted of a mobile sensing device for detecting the workerʹs approach, transmitter sets and repeaters for sending the detected information to a receiver, and exclusive software for interpreting this information. The system was applied to a real construction site and tested in order to verify its utility and efficiency. It is expected that the system will decrease the potential for fall accidents and increase the efficiency of safety management.
