Tramway Dublin Clement Bouvard 16/11/2009CTN CTN overview
The Cable Transmission Network (CTN) supports the communications
between tram stops, electrical substations and the Central Control System.
The CTN system is based on a Gigabit Ethernet (GbE) network – 1000Mbps,
using Single Mode fibre optics as the physical transmission media
The network architecture is based in four communication rings
that converges in one central node at the CCR.
Two fibre optic cables run on either side of the tracks (i.e. one
cable on the LV duct side, the other cable on the HV duct side)

overview
Overview
The Dublin LRT operates on a Line of Sight principle. In case of facing points, which can
be run in normal or reverse position, the driver can control the points according to the
expected route. After the point has been called in the correct position, the signalling logic
provides a safe locking which will maintain the point in position while the tram goes
through.
Points are operated remotely by a Control Room only in the Depots. see AVLS for details of
servers

Equipment (trackside) see AVLS for details of servers
Manufacturer:
The HFP Track Circuits are designed to detect, in a passive way, a rail vehicle and send this information to the Point Controller. This
function is based on the fact that a rail vehicle produces a short-circuit with its axles in the track area.
The minimum length of a HFP track circuit is determined by the
interaxle of the tram bogies. A minimum of two consecutive axles must be
inside the track circuit area to guarantee a safe occupation
Where there is not enough space to install a HFP Track Circuit, the HSK blocking circuit can be used. The length of a HSK Blocking Circuit is 3 to
12 meters and does not depend by the inter-axle dimension of a vehicle:
The HSK blocking circuit recognises the entry of rail vehicles passively by the
wheelshunt produced and it recognises exiting vehicles by the reduction in
vehicle mass detected.
When a vehicle crosses the HSK blocking circuit, its axles produce a short
circuit in the area of the transmitter/receiver module. As soon as the
amplitude drops below a threshold value, the HSK-blocking circuit recognises
the rail vehicle.
After detection of wheel shunt the HSK blocking circuit only monitors the
resonance frequency. When the vehicle leaves the HSK blocking circuit again,
the resonance frequency drops again. As soon as it falls below a threshold
value, the HSK blocking circuit recognises a free track segment again.

HFK Mass Detector coil are installed behind the point setting mechanism. The
system operates via an electric oscillating circuit, which indicates a change in
frequency when a rail vehicle crosses the HFK mass detector coil with its
metal mass.
For safe protection against humidity and mechanical strain mass detection
coils and electronic components are cast in a plastic frame.
The Point Setting Mechanism for the installation on the line are the models
HWE 61 AVV ZVV. The drive unit operates electro-hydraulically.
The drive and tongue detector lock machine ensures that the open and closed
point tongue is held flush in its end position.
The point setting gear is equipped with a tongue detector. Four non-wearing
inductive approach switches register the defined end positions of the open
and closed point tongue.
The gauge thickness for the Open/Close indication is made by adjusting the
proximity switches. Normally they are set to give a Point Close indication
when the distance between the tongue and the stock rail is 3mm and a Point
open indication when the same distance is 4mm.

2 HFP (track circuit) module consists of a single channel transmitter and a two-
channel receiver. The control indicators are on the front plate. The status of
each channel is shown (error, free, occupied). The current measured value
of a channel is shown on an LED strip. Located on the HFP module there is
a step switch for adjusting the operating frequency. Selecting different
operating frequencies will prevent interference between the track circuits.
3 HFK (mass detector) module consists of a single channel transmitter and a
two-channel receiver. The control indicators are on the front plate. The status
of each channel is shown (error, free, occupied). The current measured
value (of a channel) is shown on an LED strip. Slow frequency changes
(temperature drift, component drift) are recognised by the system and
automatically compensated
4 I/O modules provide the connections for the devices and systems outside
the sub-rack (e.g. end position of the point setting mechanism, signals). I/O
are opto-insulated.
5 BIS operating and information module: it displays the function and signal
status of the point controller (display of points position, malfunctions, setting
commands, last setting command, stored setting command). It is possible to
send point movement commands in local mode via the BIS
6 The voltage supply module is connected on the input side with a nominal
voltage of DC 24V. At the output is provides the voltages required for operation
of the electronic plug-in boards.
The individual modules are connected to the operating voltage through a
mains unit. The mains unit has a central cut-out which isolates the operating
voltage from the individual modules in the event of a fault.
