Midas AVR System

Jigsaw Web Services Access ...

The Midas unit is typically mounted on the dashboard or near the vehicles filler cap. The unit requires a 12 or 24 Volt feed, but draws only 10 thousandths of an Amp so wont flatten even the weakest battery.

The Midas vehicle unit holds a unique number which identifies the vehicle to the system so there is no need to enter registration numbers or set K Factors (pulses per mile) as these are all handled through the web software. This makes management of the system very simple as calibrations, vehicle unit transfers, mileage corrections etc are all handled centrally rather than having to track down the vehicle and amend information in the field. So long as a note is made of which unit is fixed to which vehicle, then the rest of the set up can be managed at a computer.

The unit is “deep potted” which means it’s sealed against water ingress and is very robust. A short lead emerges out of the back of the unit with a watertight, SureSeal connector. A mating lead extends the wiring to a place where it can be me terminated in a cleaner, dryer environment such as the vehicles cab or passenger compartment.

The vehicle units can be configured to measure distance travelled, or hours run. To measure distance travelled, the unit requires a source of distance pulses from the vehicle. Typically these would come from the output on the back of a tachograph, or a pulser fitted in the vehicles speedo cable. There are also CANBus interfaces available.

If measuring engine hours is more appropriate than distance travelled, with plant equipment for example, then the unit can be configured to count the minutes that the engine has been running. Detecting this is simple and inexpensive as the unit only requires a positive Voltage input from the vehicles ignition circuit to start the count.

The Midas key is a robust, weatherproof electronic device which is used to transfer the details from the vehicle to the fuel island controller. The keys used for Midas fuelling permanently hold the driver or fuellers ID number.

Midas Fuelling couldn’t be easier. Touch the Midas key on the vehicles Midas Unit, then touch it on the fuel island. Touching the key on the vehicle unit transfers the vehicles ID number and mileage/hours to the key. Touching the key on the Fuel Island Controller transfers that data, along with the driver/fueller ID ready to be tied to the fuelling transaction. Accurate data capture is that simple !

Driver Key – This has the Driver ID on it and is used to pass details from the vehicles Midas Reader to the Fuel Island Terminal. If the key is not touched on a Midas unit, then no fuel can be delivered.

Fueller Key - If this key is touched on a Midas unit then it functions like a driver key identifying the fueller to the system. If the key is not first touched on a Midas unit, then the fueller is prompted for details of the vehicle being fuelled according to its configured access protocol. This type of key gives the fueller more flexibility, and is a useful tool when a driver key based system is only partially fitted.

Vehicle Key – A vehicle key is used for vehicles that don’t have a Midas unit fitted to them. These operate just like Jigsaw Tags in that they are simply touched on the fuel island controller and the user follows the access protocol set up on the web site against that vehicle.

Manager Key – This is used by the system manager to access the managers functions in the Fuel Island controller.
