Researchers at UPM have developed an alarm system for construction vehicles with a low-cost radar network that can prevent collisions and improve safety in work environments.
The Radar and Microwave Group (GMR) at the Universidad Politécnica de Madrid (UPM) has developed an innovative system based on the usage of multiple radars that is installed in the vehicles creating a sensor network. This system will provide workers with a general view at the blind spots facilitating making decisions and preventing collisions.
The usage of large vehicles such as dump trucks is one of the main causes of accidents in construction sites, some of them with fatal consequences. This vehicle has numerous blind spots due to its size and design making difficult the driving and increasing the zone of collision risk.
Nowadays, there are diverse safety systems for these types of vehicles such as cameras or sirens. However, these systems do not have many advantages due to adverse conditions in construction sites. The suspended particles obstruct the camera lens and loud noises disturb the sirens. To summarize, an innovative solution was needed to solve this safety issue.
Radars are high reliability sensors hardly affected by the suspended particles, rain or fog. These radars do not need light to work and can be used in any work environment at any time. This way, GMR has developed a system based on a low-cost radar networks installed in the vehicle that detects obstacles around the vehicle and can be seen through a screen. Besides, the latest advances in electronics and processing speed allow researchers to miniaturize and to develop the proposed system.
