Developers at Georgia Tech have developed Bluetooth proximity sensing software and related hardware that can track a moving object in real time such that it can detect and alert workers in hazardous situations. The system provides alerts in the form of audible sounds and vibrations to Bluetooth enabled devices when the user is close to a predefined hazardous zone (e.g., equipment workspace, elevated edges, and holes). The system also recognizes worker’s motion patterns to detect hazardous situations (e.g., fall) and to improve job site productivity (e.g., workspace redesign). The system allows connections of multiple devices, meaning it can include multiple signal transmitters and Bluetooth enabled devices for more stable communication among the components. A cloud-server based user interface allows users to remotely monitor construction sites and get statistics in a real-time manner. This technology offers rapid connectivity, low-cost hardware, and minimal individual infrastructure requirements.
- Low-cost: Hardware is low-cost and low-energy
- More stable communication and excellent scalability: Allows connections of multiple devices
- Adjustable: Depending on the types of hazards, the proximity radius may be different to accommodate differences
- Portable: Connects to mobile devices
- Construction zones (e.g., road, buildings) to prevent hazardous proximity and location-related accidents
- Construction job site productivity analysis
Safety is one of the most important components to be addressed during construction. The work environment in the U.S construction industry has proven to be one of the most dangerous work environments among industrial segments. Workers are often exposed to hazardous proximity situations, especially when there is a high level of interaction among the workers and construction equipment. Proximity and location tracking sensing technology is a way to assist construction personnel in avoiding accidents, especially hazardous proximity incidents.
