Vehicle Tagging, either
attended or unattended
A simple example of an attended site that uses vehicle tagging is shown below:
In this scenario, the vehicle is identified using a vehicle inlet tag, which is read
by the nozzle reader. When a valid tag is presented, the PSS 5000 is able to
authorize the dispenser to start. If the connection between the vehicle tag and
nozzle reader is broken, then the dispenser stops the fuelling until the two are
reconnected. Payments for the transactions take place via the POS terminals.
2.2 Application Solutions
Combining the basic
scenarios
By combining the basic scenarios, it is possible to provide a solution for the
individual sites. The illustration below shows a combination of all the basic
scenarios, which better represents the set up of a retail petrol station forecourt:
In this scenario, the PSS 5000 controls the operations of the forecourt pumps,
price poles and payment terminals, and provides a generic interface to the
Tank Gauge System for a readout of inventory data and deliveries. The PSS
5000 also ensures that any price changes are shown correctly on both the
pumps and price poles.
Business hosts and service organizations are able to take advantage of the net-
work connection to the PSS 5000. They are able to monitor the status of the
sites, gathering diagnostics and stock movements. This helps them to perform
planned maintenance tasks, optimize wet stock deliveries, and upload new
software, which can provide new features or improve some of the current op-
erations.
