Smart Barrier


Smart Barrier allows real-time monitoring of falling debris and build up.   It uses a web platform and mobile app to issue alerts to the authority.  This low cost, reliable, low power consumption system ensures real-time detection of landslide impact on barriers.

It enhances the effectiveness of remote barriers built through the years by the Civil Engineering and Development Department (CEDD) of the Hong Kong SAR Government.   By deploying internet-of-things sensor technologies, the landslide detection and alerting system can real-time detect landslide debris impacts onto the barriers and issue instant alerts to the authority.

To improve public safety against landslides, an instant camera system with infra-red light has been developed to provide instant image and transmitted to the related department for follow-up immediately. 

An on-site Warning Message System (WMS) helps to enhance the attractiveness of the landslide warning messages using the technique of Moving Message Display and strengthen the structural support of the system to withstand the external load brought by extreme weather events.

The Smart Barrier has won the Silver Medal at the 47th International Exhibition of Inventions Geneva in 2019.
