Deployed on the G75 Lanzhou–Haikou Expressway, one of the main highways in Guangxi province, the system has already undergone extensive trials during which it successfully prevented adverse impact to road users following a landslip in March 2019.
Mr Yang Jirong, enterprise applications expert at CMCC Guangxi, said: “Immediately upon deployment, the Nokia IoT solution demonstrated the value it can deliver. As a leading operator, we are highly committed to enhancing expressway safety for all road users with 5G technology and this project is a major step forward in that goal.”
Using the system, expressway management receives real-time reports on changes in ground conditions and incline stability across highway slopes. Upon indications of a potential landslide, the system immediately notifies highway management personnel by SMS or phone call, enabling appropriate action to be taken. A 4G eye-camera deployed on the highway slope simultaneously monitors landslide status for staff members.
Cheng Gang, Executive Vice President of Nokia Shanghai Bell said: “This is an outstanding example of the benefits the Internet of Things can deliver to improve public safety. Nokia is working with the world's leading manufacturers to develop high-precision sensors and algorithms for industrial applications that can deliver all the cost-competitive benefits of easily deployed, low-power, wide-area network technology.
“We’re pleased that our system showed its worth during trials. At Nokia we believe that with the advent of 5G we can apply our IoT, analytics and wireless expertise to even more solutions that enhance levels of citizen care, well-being and security.”
The landslide monitoring and alarm system is based on the Nokia IMPACT IoT platform, comprising end-to-end Nokia hardware (Edge+ gateway and sensor nodes) and software.
Implementation of expressway slope safety evaluation, using monitoring and early warning systems, is one of the main objectives of the Ministry of Transport’s 13th Five Year Plan, and will make a major contribution to road safety.
It is of social and economic importance to establish an effective highway slope monitoring network, capable of assessing geological and environmental parameters in real time to accurately predict and prevent possible disasters.
