3. Introduction
• Metro Rail system implemented in
underground as well as flyover system.
• The two components used for the
automation of the Metro Rail systems
are
1) Programmable Logic Controllers
(PLC). &
2) Supervisory Control and Data
Acquisition (SCADA) .
4. Programmable Logic Controllers
(PLC)
• A PLC is a user-friendly, microprocessor
based specialized computer that carries
out control functions of many types and
level of complexity.
• Its purpose is to monitor crucial process
parameters and adjust process operations
accordingly.
• Hence it is used for the automation of
metro rail systems.
6. SCADA
• SCADA stands for Supervisory Control and
Data Acquisition.
• SCADA is a control system architecture that
uses computers, networked data
communications and graphical user interfaces
for high-level process supervisory
management, but uses other peripheral devices
such as Programmable Logic Controllers to
interface to the process plant or machinery.
11. Advantages
• Train locations can be identified and controlled after
interruption of power supply
• Collision of trains can be avoided.
• Accidents are avoided.
12. Disadvantages
• IR Sensors senses only particular direction.
• Wiring Connectivity is more from one sensor to other
sensor.
• This system gives information to station not the
engine operator.
13. Conclusion
• By employing PLC automation can be achieved.
• SCADA is used to track the location of Train to avoid
the accidents.
• Speed can be reduced by the sensors and Inter
Passage Door opening is provided for safety of
passengers.
14. Future scope
• By implementing PLC and SCADA in
metro rail automation the train accidents
can be prevented and many lives would
be saved.
