BACKGROUND & PRIOR ART OF THE INVENTION
[002] In conventional petrol pumps, the accounting of sales, debiting for payment and collection of charges are made by operators through manual calculation or cash registers based on recollection of the sales including the recollection of various kinds and quantities of fuel and goods sold after the completion of services.
[003] The prior art relates to various forms of petrol metering devices for use in commercial dispensing of petroleum products. Such prior art devices have been largely restricted to mechanical forms of metering and price computation. Such counting devices are well-known and utilized in nearly all present day fuel stations throughout the world. Until the recent advent of solid state electronics and low power requirement components, the prior art devices have been restricted to mechanical forms, as has been dictated by safety requirements which are inherent with exigencies surrounding petrol handling and dispensing. However, most recently there has been a great amount of activity in research and development of suitable forms of electronic calculation devices for use in fuel dispensing. There are now several electronic systems that are known and in use.

[006] US patent no 6,529,800 is directed to a control system for a
fuel dispensing system for simultaneously refueling from at least two
fuel dispensers to provide a single transaction total wherein the two
fuel dispensers are a master/satellite fuel dispenser pair. A first
communication device enables the dispenser control circuitry in the
master dispenser to control the dispensing of fuel from the satellite
dispenser. A second communication device enables the dispenser
control circuitry to receive data regarding the amount of fuel
dispensed by the satellite dispenser. A combination device generally
associated with the dispenser control circuitry combines the total
amount of fuel dispensed from the master/satellite fuel dispenser
pair to a single vehicle.

[0081 US patent no 4,216,529 discloses a system for monitoring and controlling the operation of a plurality of fluid dispensers, such as gasoline pumps or the like in a self-service gasoline station. The system includes an operating console that may be located in a ton building and has electronic displays, dispenser selecting ,_ xnttnns and a keyboard including numeric and functional

switches, all of which an operator can use to control the operation of the system.
[009] US patent no 4,290,538 discloses a fuel-dispensing system with self-checking means. A processor is used to control a price display unit for a fluid-dispensing system. The amount of fluid dispensed by the system in measured and the information responsive thereto is fed to the processor. The processor calculates the cost of the dispensed fluid and those costs are then displayed.
[010] US patents no 5,926,097 relates to a fueling system composed of plurality of fueling units; a control unit mainly for controlling signals transmitted from the fueling units, settling accounts, and indicating fueling states indoors and an outdoor fueling state indicator for indicating fueling states outdoors by receiving signals from the control unit.

[012] US patents no 3,984,032 relates to a liquid fuel dispensing system having a plurality of dispensing pumps each generating electric pulses according to the volume of fuel dispensed and a central control where payment is made. A data transmission link couples each pump to the central control and each pump has a pulse store which accumulates pulses generated by the pump during a dispensing operation. A multiplexing unit at the central control samples the outputs from the pulse stores which are updated at each sampling.

and a special range of inverters with the DSP Sine wave technology making it very safe and reliable. It offers pure sine wave output with controlled frequency, making it safe for sensitive appliances. The Jumbo inverter is ideally suited for high power appliances that require protection from surges, spikes and interruptions in input power. Starting from 6 KVA and going up to for 100 KVA, this special range is also suitable for applications like petrol pumps, deep freezers, lifts, small offices, nursing homes, data centers and cyber cafes, photocopier machines and many other applications.
[014] In stations having more advanced administrating systems, flow quantity signal transmission equipment and signal receiving devices are sometimes used. These incorporate the amount of supplied fuel and sales which are transmitted from the fuel supplying post to the office room for subsequent calculation.
[015] However, no system has therefore been devised by which a central office can fully and promptly monitor the operations of a number of fuel stations, including sales from each dispenser, inventory and other data important in planning future operations and can at the same time be assured of the accuracy of the information obtained. Nor has any such system been devised which allows the central station operator to monitor sales on a plurality of dispensers, including temporarily storing data on a previous sale and recalling the previous sale on which a further sale is continuing., At the same time it gives operator the capability of instantly determining fuel inventories and levels of fuel in each of a plurality of storage tanks.

DETAIL DESCRIPTION OF THE INVENTION WITH REFERENCE TO THE ACCOMPANYING DRAWINGS:
[026] Reference may be made to fig 1 which shows the block diagram
of an IoT based system and method for real time monitoring multiple
fuel dispensing pumps and providing power back up using power
backup system. The system comprises an IoT based central control
unit (1) positioned at remote/central location which communicates
) with the backup systems at various locations. A solar based power
backup system with card reader (2) is provided at each dispensing
unit to monitor real time individual fuel pump dispensing data,
characterized in that the backup system records the voltage and
current at mains of the motor with respect to the time during the
withdrawal of the fuel wherein the backup system communicates
th the central control unit using IoT based interface. A unique
dentity card for each personnel which need to be logged at the power

back system at the start of the working hours and taken off during off hours wherein the backup system reads the cards and communicates the details to the central unit (1). The monitoring system cumulatively collects that when that person (card holder) has started the supply and the cost is calculated. Hence the present invention has IOT based Local as well as cloud server to monitor the pump from any location.
[027] The system provides real time IOT based monitoring of fuel
dispensing and billing. The system needs to be calibrates once when
it is attached to the dispensing pump motor to assess the voltage
and current for dispensing 1 Lts and is re-calibrated if motor
changes. The calibration is done once for each motor in every petrol
pump and feeded into the system (2) and central control unit (1J, to
monitor dispenser in mains or backup mode. During dispensing, the
system calculates the current drawn by motor and time to dispense
lleter fuel and monitor current in the motor. The system also
calculates transaction data like the total gallons dispensed, cost per
gallon and the total cost of a transaction.
[028] Thus the system also alerts the pump operators about how long the fuel will last. It also indicates volume of fuel left and calculated cost of the dispensed/ remaining fuel. By remote login, all subsystems of pump dispenser are monitored by using graphical user interface at any point of presence but this is not limited to user interface forms, images and maps. Graphical representation of 5 pump dispenser facilitates to locate all locations over internet/ ethernet platform. Also, standard and query based electronic and d report generation provides specific as well as consolidated records for various pump dispensers.

[029] Numerous modifications and adaptations of the system of the present invention will be apparent to those skilled in the art, and thus it is intended by the appended claims to cover all such modifications and adaptations which fall within the true 5 spirit and scope of this invention.
