Introduction to the AGS System
The AGS System is software designed to fully automate the re-fueling process for
, and alleviating the need for manned gas stations, thereby saving money, and manpower.
There are several components to the AGS System, Remote Station Interaction from a head office, allowing polling of the pumps for Daily Transaction Records, up-to the minute station status, and remote shutdown of facilities, local pump interaction, and station re-fueling procedures.
Once the software is designed and simulated on a PC or Sparc Workstation, the code will be burned onto FPGA's for installation into special PETRO 451 Fuel pumps. Card readers will read customer credit cards, debit cards and proprietary PETRO 451 fuel cards.
The batch processing component of the AGS System coordinates the activities of the other subsystems, namely the pump subsystem, the interactive login subsystem, and the central office.

Also, this centralized approach enables a common access point for the system which facilitates communication between the various components. It also prevents too many subsystems from maintaining data independently. The implementation provides a framework for a "clean" and relatively simple design without compromising functionality.
The purpose of this component of the system is to keep track of data coming from a number of different sources (gas pumps, head office, interactive subsystem) and to integrate this information into a number of reports that are then sent off at specified intervals (every night for example). There is also a provision for these reports to be accessible interactively on a per-request basis. In this case the most up-to-date report will be made available.
The interactive central system run from PETRO 451 head office, will be essentially menu driven. There will be a computer both at the central office, and at the automated station (for maintenance and delivery purposes) on which this system will be available.
There will be two levels of access to the system. One will be for fuel delivery personnel, the other only for Petro 451 employees requiring access to status information, sales reports, etc. Depending on the level of access, the user will either be displayed a screen showing information about the tanks to be filled (fuel delivery personnel), or a menu of options giving information about station status and allowing operations such as activation and shutdown of individual pumps.
We intended that the fuel delivery person access the system at the station
instead of at Head Office.
The menus, actions, and options will take the form of graphical, clickable buttons, providing the user with a simple, easy to understand interface. The system will not allow many unexpected inputs, so errors will be kept to a minimum. At each stage of the menus, a help button will be provided which describes the action of each of the menu choices.
