Background

• What is the current system and problems in the current system?

• What is the need for implementing our project?

http://dcm.uhcl.edu/caps10g8/ 4

Introduction

• The glycol dehydration unit prototype is built by the EPIC services.

• Glycol dehydration unit is the two dimensional representation of the sample oil platform.

http://dcm.uhcl.edu/caps10g8/ 5

Objective

• Display status of the equipment every second• Record status for all equipment in the

database • Update the status of all the equipment• Design faceplate for equipment• Read instructions from a file in the USB

Database Layer

• MySQL Queries & Procedures• Record and save status for all the

equipment.

http://dcm.uhcl.edu/caps10g8/ 13

Database Access Layer

• Establish the connection with the database

• Data access classes• Synchronization between

incoming and outgoing instructions.

• Integration

http://dcm.uhcl.edu/caps10g8/ 14

Business Layer

• Generate and acknowledge warnings

• Maintain business rules• Record all the classes

http://dcm.uhcl.edu/caps10g8/ 15

Control Access Layer

• Updating the status of the physical model

• Navigate between the faceplates• Provide security• Monitor and control equipment

http://dcm.uhcl.edu/caps10g8/ 16

Physical Layer

• Display the status of the physical model

• Display history whenever requested

• Display warnings and alerts as they arise

Technologies Used

• Adobe Flex• Eclipse• Jboss• MySql

http://dcm.uhcl.edu/caps10g8/ 21

Problems Encountered

• Configuration of web server i.e. Jboss 5

• Integration of flex, eclipse and mySQL

• Working with java hibernate

http://dcm.uhcl.edu/caps10g8/ 22

Lessons Learnt

• Working in team • Time management• Professional work environment• Introduction with new

technologies like Flex Builder, JBoss

http://dcm.uhcl.edu/caps10g8/ 23

Future Work

• Adding more functionalities to the user interface & faceplates

• Deploying the developed software prototype with the serial port

• Provide system security
