SCOOTER - Seminar

  1. 1. SCADA Operating on Trains for Egyptian Railways
  2. 2. • Supervisors: * Prof.Dr. Mohammad Essam Khalifa. (Dean of Faculty of Computer and Information Science - Ain Shams University) * Dr. Hossam Faheem. * TA. Karim Emara. • Group Members: Abdalla Hassan AbdelRaheem Scientific Computing Mohammed Adel Mohammed Information Systems Mohammed Saudi AbdelSamad Computer Systems Mohammed Yehia Kamel Gawish Computer Sciences Shady Ahmed El-Melegy Computer Systems
  3. 3. Agenda • Background • Hardware Model • Problem definition • Interface Circuit • Objective • Design Tool • SCADA • References • System Architecture • Controller • Demonstrator
  4. 4. Introduction • What is SCADA ? – stands for Supervisory Control And Data Acquisition – Usually refers to centralized systems which monitor and control entire sites, or complexes of systems spread out over large areas • Components of SCADA system : – HMI – RTU (Remote Terminal Unit) – Controller Unit (PLCs)
  5. 5. Introduction: Railways • The Railways are controlled by many control towers along the trains’ paths, which control the semaphores, crosses ,…etc in a specific area
  6. 6. Background • Each of Control Towers has:  Large Control Panel.
  7. 7. Background • Each of Control Towers has:  Relays
  8. 8. Railways Background • Each of Control Towers has:  CTC - Centralized Traffic Control.
  9. 9. Background Control Tower Control Tower Control Panel Control Panel C T C Relays C T C Relays
  10. 10. Problem definition  Large control panel, which Requires Continuous costly maintenance.  Hard to control and manage.  Requires a number of operators to manage.  Poor details.
  11. 11. Objective • Provide a computerized control system for Egyptian railway stations replacing the huge control panel by a PC without changing the infrastructure . X Control Panel Relays
  12. 12. Computerized Railway control System Benefits Easy management More clear customizable details Improved alarm system notification
  13. 13. System Architecture Peripheral Interface Circuit Hardware Model Controller Demonstrator
  14. 14. Definition The controller module has the centralized control of the model, interface circuit and the demonstrator module, reflecting the changes that occur in them
  15. 15. Role & Features 1) Control the railway components 2) Show the current state of railway components 3) The ability to change the view of the displayed portion of the map 4) Alerts of the non-responding components of the railway 5) Displays information about some components
  16. 16. Hardware Model 6/26/2009
  17. 17. Why Model ? The real environment isn't available for testing Proof the concept taking in consideration the real world parameters to be controlled 6/26/2009
  18. 18. Hardware Model Components: Relays connected to the elements to be controlled Peripheral control interface : It receives the command serially from the controller software, understand it and direct it to the desired element to control it. We Chose the Microcontroller as Peripheral control interface . 6/26/2009
  19. 19. Peripheral control interface Why Microcontroller ? Easy to design and use Low design time Low cost Reprogrammable 6/26/2009
  20. 20. Circuit Schematic 6/26/2009
  21. 21. Control Process Controller software ID: a Value:1 ID =a Value = 1 Semaphore a mapped P1 Po to port 2 pin 3 8051 uC P3 P2 6/26/2009
  22. 22. Demo
  23. 23. Definition • SCOOTER Demonstrator shows how station components (Relays, Semaphores, Tracks, and Crosses) work in different situations. • Train movement mechanisms are beyond the scope of Demonstrator.
  24. 24. Role Measure the capabilities of the controller module and how it can work in complex environment and in different situations
  25. 25. Features 1) Simple User Friendly interface, Simple control using Mouse. 2) Allow Zoom in and out, Simple Moving from one station to another. 3) Set train trips based on trains database. 4) SCOOTER Demonstrator gives ability to change default behavior of Relays, Semaphores, Tracks and Crosses or demonstrate their default behavior.
  26. 26. Demo
  27. 27. Definition Design Tool is a CAD program designed specifically for the needs of model railways such Stations, Lines, Tracks, Crosses, Curves and Semaphores.
  28. 28. Features 1. Create New/Open/Save Station. 2. Add/Edit/Delete Railway. 3. Add/Edit/Delete straight Tracks, Crosses and Curves. 4. Customize Track orientation. 5. Change Track Place.
  29. 29. Demo
