Systems


Overall COMMS System: it is complex!!

13


Train-to-ground communication networks

14

To provide the situational awareness to

operators in OCC of the train operations and

passengers on board.

▪ Live streaming of multiple CCTV feeds (via

WiFi);

▪ Passenger emergency voice calls (via

TETRA);

▪ Real-time data from train management

system.

The elements to enable this capability:

Train-borneAccess point controller, Antenna, Network switch, CCTV,

PEC, Speaker etc

Train-borne systems

15

Train-borne communication system

functions as a communication gateway

between on-board operational sub-

systems with train-to-ground

communication network.

At each car:

▪ CCTV cameras;

▪ Network Video Recorder (NVR);

▪ Passenger Emergency Call;

▪ Passenger Information Display;

▪ Public Address;

For high availability, both ends of the train

are installed with:

▪ WiFi AP controllers (dual-radio), incl.

network equipment;

▪ On-board TETRA system.

Two layers:

▪ TETRA is used for vital voice

communications;

▪ WiFi (IEEE 802.11) for wireless

broadband.

For wireless broadband:

▪ Coverage along the metro lines, including

station;

▪ Mobility capability whilst train moving at

100 kmph;

▪ Capacity performance of at least 25 Mbps;

▪ Seamless handover with packet loss

<0.1% at stop, 1% on the move;

▪ Fast roaming <30ms.

Coverage overlap is needed to ensure seamless

handover (roaming) and constant data

throughput.


The backbone transmission network:

▪ Fibre backbone for all uni- & bi-directional communication

paths between stations, depot, buildings, TPSS, BSS & OCC.

▪ Dense Wavelength Division Multiplexing (DWDM) technology.

▪ 20Gbits/s transmission rate, future upgradeable

▪ LAN with Layer 3 or Layer 2 networking nodes, with 3

QoS/traffic classes (i.e mission critical application)

The backbone also provides connectivity for other rail systems such

as Automatic Fare Collection (AFC), Electronic Access Control

System (EACS), Corporate IT system.

Backbone transmission network

17

Trackside network access points (NAP) are connected to the

backbone via access switches (LAN).

Station-level communication systems

18

At station-level, operator in station control room is able to:

▪ Monitor live streaming of multiple CCTV feeds;

▪ Broadcast live or pre-recorded messages;

▪ Communicate via voice and short messages;

▪ Communicate via telephony with OCC, other stations, help points, emergency phones etc.

The communication system plays a key role in managing situations pertaining to intrusion and fire:

▪ In case of fire: signalling is informed immediately to either bypass station or move the opposite direction.

▪ In case intrusion: Controller is alerted with a CCTV pop-up, and the public announcement & passenger display system are primed.

The brain of the whole metro operations, incl. depot in all scenarios:

▪ normal

▪ degraded

▪ emergency

Traffic management.

SCADA: all systems, inclu. M&E, LV systems, substations, distribution network.

Security management – surveillance, access.

Passenger information, inclu. public address.

Communications: TETRA, WiFi, Telephony, GIRN

Network management

In emergencies situation in tunnel (fire or trains topped), SCADA system plays a central role in

▪ alerting signalling;

▪ priming the public address & passenger information.

Voice & data communication capabilities for public safety agencies

20

GIRN system installed in underground sections provides public safety agencies with two-way inter & intra agency voice & data communication for day-to-day ops & during emergency.

Dual redundancy configuration (BSR, links, path, processors, physical connections) to ensure high reliability for mission critical operation needs.

RF distribution based on:

▪ DAS for in-building;

▪ leaky for tunnel; and

▪ RF BDA for short tunnel.

Concluding thoughts

23

No proper tools

processes

Gap in scope of work

“Grey Areas”

Unavailability of

Information from others

Proper tools and process of handling is not well defined.

Adherence to defined process

Demarcation of scope of works & responsibilities between

parties are not clear.

Complete definition of system is not always available.

Coordination!

Everybody is progressing at different rates.
