Introduction

Distributed network control architectures are used for Tunnel Management Systems to provide traffic guidance,

CCTV, fire alarm, and ventilating systems while collecting several sensor data, such as vehicle detectors, VoIP

emergency phones, visibility, and other sensors. Compact and high performance Ethernet switches provide

redundant network connections

The Challenge

Prior to the new Tunnel’s opening in Norway, all of the necessary safety measures and

equipment check needed to be completed. It was required that the traffic management

engineers could monitor the status of the tunnel’s traffic in real-time traffic via

the Internet. Since the total distance of the network is greater than 100 KM

and high amount of data with high reliable transfer accuracy needed to

be sent, the problem of bandwidth and distance needed to be overcome.

Since a copper Ethernet cable Has a maximum range of

about 100 meters, the only alternative for the

Ring Topology was the use of single-mode fiber,

enabling ensuring network redundancy

and the transmission of data back

to the control center

for further analysis.

Case Study

Another necessary requirement of the Norwegian engineers was a reliable network with

redundancy and fast recovery function in case a node fails. Due to the large number of modules equipped with

the system such as Speed detectors, Smoke detectors, Temperature detectors, PIS LED information board,

PoE IP Camera for real-video monitoring, Voice broadcasting system, PoE IP Phone, License Plate

Recognition System and Traffic Light control, a reliable and fast redundancy network was essential.

Another important requirement of the tunnel management team in Norway was the 24/7 on-site

video surveillance of the tunnel. The non-stop tunnel surveillance in combination with the harsh operating

environment within the tunnel demanded a high tech, innovative and “intelligent” system of Ethernet devices

and cameras. The system was expected to support wide temperatures of an industrial grade form. Furthermore,

since all the equipment would be installed outdoors, the entire mechanism must be able to withstand harsh

environmental conditions. Normally, standard PoE switches only support 15.4W which is sufficient for fixed IP

cameras. However planned upgrades could include the need for high power PTZ cameras which would need

PoE+ (25.5W)

The Solution

The System Integrator (SI) in Norway chose Advantech’s industrial switch EKI-7710E-2CPI as its

interface includes eight 10/100 RJ-45 and supports IEEE 802.3 af/at Power-over-Ethernet (PoE) Fast Ethernet

ports + two Gigabit Copper/SFP (Small Form Pluggable) fiber combo ports. The EKI-7710E-2CPI is a full

managed industrial switch with wide operating temperature from -40 to +75°C.

Each of the Ethernet ports (ports1~8) provides up to 30W power to connected devices. That

eliminated the need to run dedicated power lines to the camera locations. In addition, the EKI-7710E-2CPI

supports POE port monitoring and configuration through the interface as shown below. Administrators and

operators can monitor the power consumption and voltage and temperature from the managed switch

interface.

Case Study

The flexible network topology, as shown below, supports multiple dual-ring networks from the control

center. Each ring’s ID supports one tunnel and is flexible enough to be extended in the future.

The SFP fiber ports support dual mode 100 Mbps or 1000 Mbps SFP auto detection which future-proofs

the installation.

There are many benefits of fiber:

1. Long distances up to 120KM

2. Immunity against Electromagnetic Interference (EMI)

3. Immunity against Electro-Static Discharge (ESD) and Surges

The Features

The terminal block on the top of the device supports dual DC power

24/48VDC input.

The Fault relay and fault LED indicate failed connection on power 1 /

power 2 or link status on the SFP fiber ports. The fault relay is a

switch where normal function is closed and fault is open.

Administrators can use these functions in the control room: the fault

LED indicates the power and (or) SFP fiber port link status, if power

or SFP fiber ports fail, the fault alarm LED will be on and SNMP can

receive the trap. All the EKI-7700 series products support 5 years

warranty.

All EKI-7710E-2CPI support IXM fast deployment technology. For a

whole new environment, engineers can assign new IP addresses for

each switch and then restore flexible software functions to the

EKI-7710E-2CPI. For existing environments, engineers need to

upgrade to a new firmware by using IXM for fast deployment of the

latest firmware to all of their EKI-7710E-2CPI devices just by following

the wizard. Below is the reference website introducing IXM

technology:

The EKI-7710E-2CPI also supports X-ring Pro technology, a

maximum of 250 devices and also popular protocols like VLAN

(Virtual Local Area Network), IGMP V1, V2, V3 for multicast video

streaming.

The Product:

EKI-7700 series with PoE+ technology

The PoE+ features meet IEEE 802.3af /at standards for running

electrical DC power over existing Category5 (or higher) copper

cabling, while concurrently supporting the Ethernet data stream. To

prevent damage to connected equipment, the detected circuit will

only provide as much power as the equipment actually draws.
