The
advanced Signalling & Train Control technology, Communication Based Train
Control (CBTC), has been deployed in Hyderabad Metro in order to ensure better
control of the trains. Hyderabad Metro would be the first such Metro in India
to claim trains controlled by CBTC technology. The trains, which ply on three
corridors would be controlled and also monitored from the state-of-the-art
Operation Control Centre (OCC) located at Uppal Depot.
This
ensures that trains can operate with a headway of 90 Seconds for tackling
commuter rush during office peak hours while the overview display panel shows
information of all the three corridors, indicating the current locations of all
the trains operating on these corridors.
The
OCC is considered the primary control centre, which would have back-up control
centre at Uppal depot to take over the operations in case of an emergency.
Local ATS at station and VDU at the interlocking stations also control the
train when needed. Axle Counter based Fall-Back system would be deployed as
secondary train detection system in across the three corridors as a backup for
CBTC operation. The two major depots at Uppal and Miyapur would be controlled
and also monitored from the independent control centres based at Uppal and
Miyapur. The signalling system at the depots is based on the redundant and
high-end Computer Based Interlocking (CBI) system.
The
trains of Hyderabad Metro operate on Automatic Train Operation (ATO) that
continuously monitors safe train operations and initiates necessary actions in
situation where the trains do not perform as desired. The station equipments such as Computer Based
Interlocking (CBI), wayside ATP etc., are critical signalling equipments for
ensuring safe and uninterrupted train operations. Passenger Emergency Stop
Plungers are also provided at every platform and at Station Control Rooms (SCR)
to halt a train immediately during emergency.
Power
Supply, Traction and SCADA System
Hyderabad
Metro Rail features three elevated corridors with a standard gauge system. For
minimizing interference with the main communication lines, Booster Transformers
are installed provided across the three corridors at specified locations. Receiving Substations (RSS) deployed at
Uppal, Yusufguda, Miyapur & MGBS receive the power supply.
SCADA
System
Hyderabad
Metro’s Supervisory Control and Data Acquisition system offers the highest
level of support for monitoring, controlling and command. A centralized OCC
i.e. Operation Control Centre located at Uppal Depot controls the entire Power
Supply and Traction system Equipment by means of SCADA.
Telecom
System
The
state-of-the-art communication system of Hyderabad Metro continuous
communication between the central control, train operators as well as station
controllers. These are reliable, redundant modular and proven systems. All
communication sub-systems support the IP and integrated through GE (IP) Network
i.e. Gigabit Ethernet based IP Backbone System. There are provisions for
emergency Call Point/help-point phone at Metro stations to assist passengers in
case of any emergency. PoE based and complete IP based CCTV surveillance
monitors the entire passenger areas of all stations.
