1-4. ISLANDER PLUS STRUCTURE
1-4.1. Main Components
Following is a short description of the Islander PLUS main sub units (see Figure 1-3 and
Figure 1-5):
Orpak Controller Unit (OrCU)
Orpak Controller Unit (OrCU) is a complete
forecourt controller with its own embedded
operating system. The unit consists of an
embedded hardware platform with a solid state
Flash hard disk, Real Time Clock (RTC) with
back up, along with surge suppressors for
transient and noise immunity
OrCU features two separate and isolated networks
(TCP/IP over Ethernet). One network links the
Islander PLUS system components. The second
network is intended for external remote
communication (Head Office, 3
rd
party systems).
This network is protected by SSL security.
OrCU includes a built-in server for Web access trough an internet browser (Explorer).
Wireless Gateway Terminal (WGT) (Optional)
WGT (Wireless Gateway Terminal) receives both
DataPass and FuelOpass vehicle data, decrypts the
information and transmits it to the Station automation
system in a secure manner over an RF signal.
To obtain maximal grid availability, several WGT units
are installed at the station to create a robust 'mesh'
network. This setup enables the RF signal to travel through various routes and bypass possible
interferences (such as a big truck/bus).
The units that provide data to the WGT are:
DataPass - DataPass is a miniature unit that connects to the vehicle bus and captures data from the
vehicle CPU/BUS. It then transmits this data to the nearest Wireless Gateway Terminal (WGT) in
the forecourt.
FuelOpass - FuelOpass is a passive vehicle identification tag for refueling. Its encrypted data
includes the account to be charged and is read by the Nozzle Reader device using RFID contactless
technology.
Nozzle Reader (NR) - Nozzle Reader is a self contained unit installed on the nozzle which reads
the FuelOpass data using contactless technology.
