On Track Innovations Ltd OTI-EFVID ユーザーズマニュアル

Easy Fuel combines Long-range and Proximity RF technologies offering a 
revolutionary solution to gasoline management. 

Long range RF communication between the station fueling controller and 
the vehicles, combined with a short range proximity RF communication 
between the vehicles and the fueling nozzles, enable quick and easy secured 
controlled refueling transactions.  

The RF communication replaces hardwired communication between station 
components, hence greatly simplifying system installation at the gasoline 
station and reducing the maintenance expenses.  
For standard installations the RF frequency is in the range of 902-928MHz 
as required by the applications. 
For special applications which are reached with high power RFID systems 
radiation (up to 4W between 902.5-927.5 MHz) a special off-
communication channel is selected at 902.1 MHz.  

EF system comprises three elements: 

•

  NID (Nozzle IDentification unit):  

A very low power RF transmitter, mounted on the refueling 
nozzles. The NID periodically transmit its ID when off 
hook. 
This ID is used to identify the specific requested nozzle to 
the station controller. 

•

  VID (Vehicle IDentification unit): 

The VID is mounted in the vehicle. 
It is connected to fuel inlet antenna to retrieve the Nozzle 
ID and to an RF antenna to communicate with the SC. 

•

  SC (Site Controller): 

The SC is usually mounted at the station office. 
It communicates with the vehicles VIDs via an RF antenna 
and with the station controller via serial communication 
line.
