RFID Application: Automatic Vehicle Identification in gas refueling station.

RFID Application: Automatic Vehicle Identification for auto payment in gas refueling station.

Gas for vehicles, also known as CNG (Compressed Natural Gas) or Compressed Natural Gas obtained through the compression process of methane (CH4) the extraction of natural gas with a pressure of 200 s / d 275 BAR. The composition of methane (CH4) which has a fraction lighter than air, making CNG will be released into the air at once, when the leak so relatih safer than the fuel oil.

The use of CNG as fuel, much cleaner and friendlier to the environment than the fuel oil, this is due to CNG produces fewer emissions compared with Fuel (1/3 fuel emission levels), in addition to the content of octane (RON - Research Octane Number) of 120, CNG is also able to produce cleaner burning, so that the vehicle's engine is more durable with an efficient treatment.

Vehicles usually wear converter kit which can be fueled by hybrid with manual shift or automatic use CNG or gasoline.

RFID application this time is to automatically detect vehicles that will fill CNG and process the data on the database server and issue invoices bills on the company or individual.

Tag used to be relatively low cost because of this tag will be affixed to the vehicle, the driver's windshield, usually kind of windshield sticker or variants commonly used for this, with a note to avoid glass films containing metal concentrates.

The type of reader that is used on the entrance gate is a type of long range with installation following the standards and degree following the hardware datasheet, so the best position to be obtained at its optimum performance.

The process is as follows:

• Vehicle(s) enter Gas refueling station through the entrance or gate where fitted Long range RFID reader

• Long Range RFID reader reads the information on the tag affixed to the windshield of the vehicle (vehicle Automatic Identification)

• Long Range RFID reader informs the server and this information also displayed on the island monitor(s) SPBG

• Refueling Officer, choose the display monitor vehicle license plates number that appear and perform charging by the number of customers who have been determined

• Finish filling, all the information is sent to the server and published a letter printed for billing to the company or paid directly.

Tags can also contain micro money or points which can also be used for payment with a prepaid system for example, so that the refueling process faster, by directly cutting the contents of micro money or point on the tag.

Another innovation is still a lot of open and developed for applications of this kind.

The advantage of this system:

• The process is more accurate vehicle administration, particularly for public transport company (taxi / bus) which requires the calculation of fuel consumption (cost) and earned income.

• refueling process becomes more effective and accurate.

• Financial transactions electronically, it is faster and more positive side

ELEV-8 Li-Po Battery Pack

ELEV-8 Li-Po Battery Pack is rechargeable Lithium Polymer (LiPo) battery is perfect for RC and small robotic applications, such as our ELEV-8 v2 Quadcopter Kit (#80200). LiPo batteries are very popular due to their very high energy density (amp-hours to weight ratio) compared to NiCds or other batteries.

To charge the battery you will need a Lithium Polymer Balance Charger capable of charging a 3 cell (11.1 volt) battery.

Key Features:

• 66 amp continuous output can power your high-power projects
• 3.5mm “female” bullet connectors pre-soldered onto each lead.
• Balance charging cable can also attach to a low-voltage alarm
• 3.5" stranded 12AWG power cable with silicon insulation

Application Ideas:

• Remote-Controlled Model Aircraft
• Solar Power Station
• Weather Station Power

WARNING: Lithium Polymer (LiPo) batteries are volatile. Failure to read and follow the all safety instructions and warnings may result in fire, personal injury and damage to property if charged or used improperly.

ELEV-8 V2 Quadcopter Kit

ELEV-8 your skills with this extremely durable and stylish multirotor; great for first-time flyers and experienced aviators alike.  You'll be guided through every step of the assembly process with our exceptional online documentation and support.  Easy to repair and open-source, the versatile ELEV-8 has endless potential applications: from recreational flying, to unparalleled, hands-on multirotor education, to professional aerial photography or video.

The ELEV-8 Quadcopter is lifted and propelled by four rotors (vertically-oriented propellers). Electronic Speed Controllers power each motor/rotor independently, so that by altering the relative rotational rates of these rotors, the ELEV-8 is able to move in any direction. A HoverflyOPEN Flight Controller powered by a Parallax Propeller 1 multicore microcontroller provides stabilization, creating a small, maneuverable, and agile aircraft.

An RC transmitter & receiver and lithium-polymer battery & charger are required, not included.

Optional Additional Items Required (not included)

• Radio Control Transmitter and Receiver; 5-channel minimum required for flight. The recommend hardware are the Spektrum DX6i transmitter and matching Spektrum AR610 receiver (or OrangeRX R615); this setup will accommodate simple projects requiring one extra servo. If you anticipate building more sophisticated projects, such as controlled camera gimbals,  the Spektrum DX8 and matching Spektrum AR8000 receiver (or OrangeRC R800X) and Spektrum TM1000 telemetry transmitter. While this equipment is somewhat expensive, it is high-quality and will accommodate both your current and future needs.
• Lithium Polymer (LiPo) battery with 3000 to 4400 mAh capacity and minimum 20C discharge rate.
• “LiPo Balance Charger” (packaging should have those exact words). Using a charger not designed for LiPo batteries will cause the battery to flame and release toxic smoke.
• A LiPo Low-Voltage Alarm. These will alert you with a very loud buzzer when your battery voltage gets low, significantly reducing the risk of damaging your battery or crashing your ELEV-8.
