The sensor-supported localization of construction site lights enables the automated recording of the spatial and temporal extent of construction sites in the Digital Twin Munich. This allows construction site areas to be visualized in real time.
State-of-the-art roadworks lights can use integrated sensors to detect and automatically transmit their position on the road. The interconnected use of several of these systems makes it possible to track the position and extent of the roadworks area over time. In a pilot project, several of these lights were installed on safety beacons for testing purposes and the recorded data was transferred to the DT-M. The lights are approved safety beacon lights certified by BASt, which are equipped with GNSS receivers and send their position to an IoT platform of the light manufacturers via mobile data connections. This data is retrieved from the platform and integrated into the DT-M. By networking several lights, an area-wide construction site perimeter can be derived, which is compared with the construction site plans and used to monitor the construction sites. In addition to the position of the light, for which an accuracy of less than 0.5 m is aimed for, further information such as battery charge status, temperature etc. is transmitted. In addition, a warning message is sent if the position of the light changes.
