Tunnel Traffic Monitoring
The disastrous fires and everyday accidents lead to a major
reappraisal of tunnel safety. As a result, latest video surveillance
technologies are being installed to ensure the highest level of safety
and fast reaction in emergency situations. However, some challenges
need to be addressed, including the relatively humid, dusty and salty
environmental conditions in tunnels, the frequent vibration of
equipment caused by moving heavy vehicles, etc.
For the system integrating company Korenix JetNet 3706-RJ
appeared to be a great solution, which solved all these problems and,
in addition, reduced the impact to heavy traffic by shortening the
construction and future maintenance time.
JetNet 3706-RJ
rugged switches installed in underground tunnels powered the IP
cameras and transferred the captured streams to the monitoring center.
To overcome the long distance between the traffic center and the pole, JetCon 3401G gigabit media converters where used as intermediate devices.

With six IP67 rated RJ45 ports, the JetNet3706-RJ
outdoor PoE switches are easy to install. As a result, they reduce
wiring costs and provide secure and highly reliable waterproof,
dust-tight, anti-vibration connection. In addition, the 4 PoE ports of JetNet 3706-RJ
make it possible to extend power deployments to the most inaccessible
areas and reduce maintenance time, thus the overall costs, too. Due to
its outstanding mechanical design and capability of operating in -40 ~
+70oC wide temperature range, JetNet 3706-RJ
can be easily adopted in difficult to wire tunnel applications
providing the most rugged solutions for reliable IP surveillance
network construction.

The real-time traffic monitoring of tunnels from the control center is becoming possible when additional JetCon 3401G gigabit converters are installed. These converters receive millions of video streams from IP cameras via JetNet 3706-RJ
and through gigabit optic fibers transfer these high bandwidth data to
the central room. With its rugged design in addition to the excellent
traffic handling and the active link loss forwarding technologies, JetCon 3401G enlarges network performance and keeps the data transfer running non-stop in severe conditions.
The overall network system provided by Korenix, with the installation of JetNet 3706-RJ and JetCon 3401G became
an ideal efficient and cost-effective solution for the System
Integrating company to design a real-time traffic management and
monitoring in harsh tunnel applications.

Due to the increasing complexity of traffic flow in the highways with the desire for advanced mobility, safety, security or other environmental issues, the role of reliable and congestion-free road traffic management is becoming more and more crucial. To ensure the non-stop transmission of a large number of video and audio flows from widely-located road sites to the monitoring room, high-speed gigabit Ethernet and fiber connections are required to be used in harsh industrial environments.

The plans of security surveillance are already underway to ensure the safety of all people taking public bus in Spain. However, there are some challenges revealed: Firstly, there could be the extra costs of wiring for each IP camera since 4 IP cameras would be required in one bus. Secondly, the temperature in the cabinet is relatively high due to the heat generated from the plastic roof; therefore the commercial switches could have difficulty sustaining under the heating environment.
