Introduction

EasyFuelPlus (EFP) is an automated refueling system based on wireless communication between the system components.
The system utilizes 13.56MHz proximity technology for interfacing between the vehicle (equipped with passive RFID tag) and the refueling nozzle (equipped with Mini RFN unit), and longer-range UHF communication for wireless interfacing between the refueling nozzle to the EF Site Controller which is mounted atthe site office.

The Mini RFN unit, together with the Passive Vehicle Tag, is OTI PetroSmart’s latest addition to the EFP family which also includes:

• EF-SC (Site Controller)

  • The Site Controller is an RF transceiver, mounted on a pedestal or in the site office, serving as an interface between the EFP system and the station refueling control system. It operates at 433MHz or
    902- 928MHz frequency ranges, depending on the locally allocated frequency slots.

• EF-VID (Vehicle IDentification) Vehicle Tag

  • The VID is a microcontroller-based in-vehicle device, that communicates with the Site Controller using a Window Mount Antenna. The Passive Tag in this case serves as an identifier of the fuel inlet, and whose serial number is mapped in the VID to create the association. The information stored in the VID may include more sophisticated data elements like the odometer and engine hour readings. The EF VID derives its power from the vehicle battery.

MiniRFN

Product Description

The MRFN (Mini RFN) is mounted on the refueling nozzle and serves as an interface between the refueled vehicle and the station SC (Site Controller). It facilitates controlled and secured refueling. It is a battery powered unit, comprising two different transceivers:

• RFID 13.56MHz Transceiver:
  • Communicates with the Vehicle Passive Tag.
• SC UHF transceiver:
  • Communicates with the refueling station SC.

All the transceivers operate under the control of a local microprocessor.

Product Features

• Bi-directional proximity 13.56MHz interface with Passive Vehicle Tags according to ISO15693 Vicinity Cards Standard.
• Long range UHF interface to the Site Controller.
• Tamperproof system to prevent its unauthorized removal from the nozzle.
• User defined LED indicator.
• Accelerometer used to detect removal from nozzle prior to refueling.
• Flexible, software configurable microprocessor-based design.
• Compliance with FCC Section 15 Radio requirements.
• Compliance with IEC/EN60079-0 & IEC/EN60079-11 safety requirements for operation in Hazardous area.
• Operating temperature range -20° to +60°C (-4° to 140°F).
• Powered by replaceable Lithium battery unit.
• Quick and simple installation.

Operation Scenario

Vehicle only with a Passive RFID Tag:

When the nozzle is inserted into the vehicle fueling inlet, the MRFN reads the relevant vehicle refueling data from the Passive RFID Vehicle Tag and transmits it together with its own identity data to the Site Controller.
Fuel is dispensed once the transaction is authorized. Fuel is dispensed as long as the MRFN detects the presence of the Passive RFID Vehicle Tag. If the nozzle is retracted from the refueling inlet,so that the RFID Vehicle Tag is not detected, the MRFN informs the system to stop dispensing fuel.

Installation

Mounting the Mini RFN

• The components comprising the Mini RFN Unit are shown below. It should be noted that the Reader Unit is frequency specific (434/902-928MHz) and as such, the correct Reader Unit is to be selected for use depending on the allowed frequency bands at the country of intended operation.
• The metal bracket is supplied with two M4 Screws and 2 x Nord Lock Washers for securing the Mini RFN Reader unit. The Battery Pack is supplied with 2 x 3/16 Screws for securing it to the MRFN Reader unit.

Assembly Procedure (shown for an OPW7H Nozzle):

• Install the Metal Mounting Band around the trigger section of the nozzle:
• Insert the Mini RFN on the nozzle spout and slide it onto the metal part, after which the 2 x M4 with their Nordlock Washers are to be inserted into the thread and tightened with a star screwdriver.
• Mount the Battery Unit on the Reader Unit and fasten it using the 2 x 6/32” Screws.
• After tightening the Battery pack Unit Screws, the Red LED will start blinking for approximately 40-seconds after which the RFN is operational.

Initialization

For correct field operation, the MRFN needs to be configured with a few parameters associated with the specific installation. The most important parameter is its logical ID number associated with the specific nozzle it is mounted on. The configuration is performed utilizing a laptop in conjunction with a Smart Tag Issuing Unit.
