  1. GUI For A Virtual Pipeline Simulation Testbed By, Revathi Manni Ranganathan Major Professor: Dr.Virgil Wallentine

  2. Agenda • Pipeline Editor – Introduction • Previous Work by Oyenan • New Requirements • Design and implementation • User Feedback • Demo

  3. Pipeline Editor- An introduction • Tool to create and manipulate virtual pipeline systems. • Window to the Simulators • Cut, Copy, Paste, drag and drop • Store / Retrieve pipeline system in .vps format • Visualize the results

  4. Pipeline Editor • Developed using Java Swing, JGraph, Oracle 8i • Can be started on a remote machine • Requirements – Java Web Start, Web browser, JDBC driver • Connects to the Simulator on the remote server

  5. JGraph • Graph drawing component purely in Java Swing • Based on Model-View-Controller framework • Graph Theory + Swing Architecture = JGraph • Provides cut, copy, paste, drag & drop, zoom

  6. Pipeline Editor – A snapshot

  7. Earlier Work by Oyenan • Basic Version of the GUI • Editor built on top of JGraph • Modeling of pipeline components – pipes, compressors • Job Control Optimizer • Result Visualization

  8. New Requirements • Connector – generic type • Modification of Pipe • Compression Units • Connection to the Parallel Simulator • Connection to the Sequential Simulator

  9. Connector • Generic Type Component • Multiple incoming and outgoing branches • Number decided by the user at run time • Replaces 2-way & 3-way Split, 2-way & 3way Combine

  10. Pipes • Should support visualization of the leftmost and rightmost nodes • Implemented by class MyEdge – extension of JGraph’s Edge • Required modification in DataCell

  11. Pipe – Snap Shot

  12. Compression Units • Generic Type Component • Comprises of a Driver and Compressor • Four Basic types – • Reciprocating Engine – Reciprocating Compressor • Gas Turbine – Centrifugal Compressor • Reciprocating Engine – Centrifugal Compressor • Gas Turbine – Reciprocating Compressor

  13. Compression Unit - Design • Different models under each type • Properties can be grouped meaningfully – Simulation Data, Operational Data, Manufacturer’s Data • Type and model name can be chosen at run time. • New models can be created and stored in the database

  14. Compression Units-Snap Shot

  15. Database Design

  16. Adaptations • Customized UserObject for each component • Customized method to draw property panel • Provision to group properties meaningfully

  17. GUI- Parallel Simulator • Connection is through sockets • Two separate threads are used to avoid GUI freezing • SimulatorClient – send user commands • SimulatorDataClient – get data and status

  18. GUI-Parallel Simulator

  19. GUI to Parallel Simulator-Snap Shot

  20. GUI-Sequential Simulator • Communication is through text files in ASCII format • Input text file contains graph data • Output text file contains simulation data • Option to set global parameters available for input text file.

  21. GUI-Sequential Simulator • GraphParser – Input text file generator • Covert .vps to .txt

  22. Sequential Simulator - GUI • The Sequential Simulator generates output in standard text format. • The text file is parsed by the GUI to create a live simulation effect • Simulation is the same as replay

  23. Sequential Simulator - GUI

  24. GUI to Simulators - Supported Features • Simulate (Only in Parallel version) • Replay • Stop • Pause / Resume • Step / Skip Forward • Step / Skip Backward

  25. Class Diagram

  26. User Feedback • “The GUI application fully implements these features and let users construct a natural gas pipeline system via drag-and-drop. The interface is very friendly. It can send requests to the server (simulator) and display the results back from the server in real-time. In the future, more components may be supported. The display of the results may be improved. In a word, the GUI is excellent.” - Liubo Chen, Programmer – Parallel Simulator • “The GUI for the VPST is a very useful tool for the user to create any pipeline network and run the simulation process. The GUI in its present form contains all the basic components that a Pipeline network comprises off. - Ravi Kiran Addanki, Programmer – Sequential Simulator

  27. Conclusion • The new requirements have been satisfied • The basic software has been adapted to meet the complex demands • The tool is fully functional with minimum system requirements

  28. Pipeline Editor in Action -A Demo
