Tunnel Monitoring System for Superhighways in Yunnan, China
Industry Application: Tunnel ManagementIndustry Sector: TransportationLocation: Yunnan, China
The highways in Yunnan are complex and feature many long winding sections. Given the influence of fluctuating traffic levels, periodic extreme weather conditions, varying road profiles, and a range of topographical features, it is crucial that a reliable monitoring system be in place to provide real-time information on environmental conditions inside the tunnels. This would also contribute to mitigating climate change by reducing traffic congestion due to accidents or breakdowns.
- Accurately monitor road traffic and weather conditions to maintain control over road operations
- Detect and manage latent safety issues and reduce the number/severity of traffic accidents
- Minimize the effect of incidents, accidents, and poor weather on the traffic
- Guide and control traffic by using modelling to improve traffic flow during peak periods

IoT Application Software Platform
In this system, EKI-7710G switches are employed to collect data from the various equipment and devices in the tunnel and form a network ring for data redundancy purpose; all data is then transmitted to EKI-9428G layer 3 switch in the control room. Advantech’s EKI-7700 series of industrial management Ethernet switches allow users to quickly scale up their industrial networks in a cost-effective manner. Their robust design also ensures reliability and stability, while Advantech’s X-Ring technology gives the shortest available recovery time (<10 ms), thus improving both the reliability and speed of network infrastructure.
Finally, control over the logic configuration for network nodes, control computation, I/O points for field connections, and field network management is realized using Advantech’s WebAccess software solution. This software provides a means for system monitoring through the creation of widgets and user interfaces for visualizing data and displaying alerts as well as general functions such as printing and computer network management. To do this, it combines multiple information technologies, including geographic information system (GIS), SCADA, multimedia, and network security technologies, thus providing a unified platform for viewing GIS images and monitoring data in real time.
