This simple, cost-effective design also has proven
track record automatic coupler applications. LOKEL opted for
HARTING Ethernet switches for this application. fault occurs

with redundant links, namely the trunking function. in
Ostrava-Hrabůvka has developed digital control and
camera system for the new ED74 commuter train which
has four cars and meters long. The
solution provides safe, dependable performance the
network under any operating conditions.
The network includes
• Video servers for signal transm ission
• monitors display the images from the cameras
• Industrial PCs record the images
• Ethernet switches provide connectivity between the
network components
• GSM module for Internet access
The trunking function
An automatic coupler connects the electrical and pneu
matic lines between trains. Twelve
cameras provide real time surveillance the passenger
com partm ents. LOKEL developed
the software for recording and displaying the images
that are captured the cameras. A
logical Ethernet connection can established between
2x2 physical ports using this function. The system records images from all
cameras full video stream quality.
