GUI For A Virtual Pipeline Simulation Testbed

By,Revathi Manni Ranganathan

Major Professor:Dr.Virgil Wallentine

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

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

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

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

Pipeline Editor – A snapshot

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

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

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

Pipes Should support visualization of the leftmost and

rightmost nodes Implemented by class MyEdge – extension of

JGraph’s Edge Required modification in DataCell

Pipe – Snap Shot

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

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

Compression Units-Snap Shot

Database Design

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

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

GUI-Parallel Simulator

GUI to Parallel Simulator-Snap Shot

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.

GUI-Sequential Simulator

GraphParser – Input text file generator Covert .vps to .txt

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

Sequential Simulator - GUI

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

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

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
