A summary by scientists at Hong Kong Polytechnic University about a newly developed system for construction site safety monitoring.

We have developed a system for construction safety, called S-Helmet, based on our real-time localization technique. S-Helmet can track workers’ real-time locations with desirable accuracy. When a worker is moving near danger zones, the helmet will automatically issue an alarm. The helmet can also be equipped with other sensors to monitor the worker’s health condition. 

The S-Helmet can provide traces of works and moving objects. By mining the historical traces, we can analyze workers’ safety associated behavior and improve construction site safety management. S-Helmet can effectively help to avoid the construction site accidents and improve healthcare condition of workers. The system will have substantial impact on the construction safety.

Special features and advantages

1.High accuracy: The localization error of S-Helmet is 1~2 meters
2.High update frequency: The real-time location information can be
   updated every second
3.Ease of deployment: The system can be easily to be deployed on
   the construction sites

Applications

1. Construction site management: To help to improve the safety of
    construction worker in construction site
2. Coal-mine applications: To help to provide the real-time
    localization of coal-mine workers
