Smart Barrier System


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

Problem addressed

To improve public safety against landslides, this system adopted internet-of-things sensor technologies to detect the impact of landslide debris on the barriers in real time and issue instant alerts to the authority for follow-up actions.

  • An instant camera system with infrared light has been developed to provide images and instantly transmit them to the related departments for follow-ups.
  • An on-site Warning Message System (WMS) helps deliver the landslide warning messages by using the technique of Moving Message Display and the structure of the system is strengthened to withstand the external load brought by extreme weather.
Key impact
  • The system enhances the effectiveness of the remote barriers built by the Civil Engineering and Development Department (CEDD) of the HK SAR Government throughout the years.
  • The system helps to remind the public not to stay too close to the high-risk areas during adverse weather, which can mitigate the risk of landslide hazards in natural terrains.
