ABSTRACT

In current days the petrol stations are operated manually. These petrol pumps are time consuming and require more manpower. To place petrol stations in distant area it very costly to provide excellent facility to the consumers all these problem are sorted out by the use of unmanned power pump which requires less time to operate and it is effective and can be installed anywhere the customer self going to avail the services the payment is done by electronic clearing system. These petrol stations easily monitor with the video capturing and alarming system over the time by a central control unit.

INTRODUCTION

Unmanned petrol station

Today’s consumers are more mobile — and more demanding than ever. Consumers want more choices, more speed and more convenience. They’re less forgiving of slow pumps and outdated features and searching for petrol station all over the place . To upgrade market we need a dispenser that is reliable, user-friendly and ready to increase our profitability. We need unmanned petrol station. Designed from the ground up, this flexible, dependable and scalable fuel dispenser will meet our needs, today and tomorrow.

The world’s most consumer-friendly fuel dispenser. The world’s most consumer-friendly fuel pump. It has the easy operated ATM machine. It had easy operated graphics user interface (GUI). It is interface with high speed petrol dispenser which is convenient for consumer to operate

Centralized control unit As in today world men have no time to waste in this competitive world for the search of petrol. Centralized control unit can easily access many number of unmanned petrol stations situated at various locations. As by this technology we can reduce our expenditure, we can generate more revenue from it.

Security from the outside Unmanned petrol stations are growing in popularity largely to the fact that they provide petrol at reduced prices.

We understand that theft and fraud are a growing concern for today’s retailers. So we have applied our innovation toward developing dispensers that deter criminal activity

However not having a person keeping an eye on the customers or the station changes the security requirements. The customers need to feel safe when filling up and any vandalism to the station has to be quickly identified. We provide an all encompassing security system that can constantly monitor

multiple petrol stations from a central location, ensuring the customers and stations well being at all times.

Video surveillance of the station at all times Customers are only a push button away if assistance is

needed Pumps and pay terminals are constantly monitored One central monitoring point for multiple stations

HARDWARE REQUIREMENT

GENERAL SPECIFICATION Display New backlight display with 10+9+8 digits.Selectively, 7+6+5 digits can also be applied. Card Reader/Optional Double purpose integrated card reader which is capable to read and write both magnetic and smart cards. Printer/Optional Dual purpose thermal printer with cutter which is used both for sales as well as promotion campaign receipts.

Intelligent Meter Thank to the intelligent meter, equipment with hall-effect sensor and micro processor, separate Electronic calibration for each meter and fault recognition is possible and it can Communicate with site controller via RS 485 communication interface. Proportional Valve The new proportional valve provides more accurate deliveries than traditional double stage solenoid valves.

Modular Hydraulic The hydraulic units used in dispensers; because of its modeler design, gives you the Following advantages, reduced number of component. Easy maintenance, reduced dimension and weight. Filter flanged to the main body. Coupling Connected Drive Mechanism Pump-motor connection has been realized by means of a coupling. Through this coupling Connection system problems arising from pulley and belt system has been avoided and Security in service has been obtained. Nozzle and Swivel ¾ “Automatic Nozzle, with a swivel allowing 360movement for smooth operation and Prevention of hose fractures. High Speed Suction Pump Efficiency can be Rosen up to 90lt./min.

SOFTWARE REQUIREMENT

Programming in C Programming in C is required for the programming of micro-controller which control the flow rate of fluid in container Programming in Visual Basic Programming in visual basic is required to make easy for consumer to operate ATM machine.

FUTURE APPLICATION

Unmanned petrol station was required for over the years to

fulfill the requirement of consumers over the wide area.

Unmanned petrol station concept is not limited petrol station, but it can be applicable for the availability of food grades at long distinct area.

It can make human more safe from robbery, fraud, and any other unwanted incidences by the use of plastic money.
