RFID BASED PREPAID CARD FOR PETROL STATION WITH STILL IMAGES USING RASPBERRY PI

Abstract

The main aim of the project is to design a system which is capable of automatically deducting the amount for petrol dispensed from user card based on RFID technology. Liquid dispensing systems are quite commonly found in our daily life in different places like offices, Bus stands, Railway stations, Petrol pumps. Here we are going to present modern era petrol dispensing system which is meant to be operated with prepaid card using RFID technology. The project mainly aims in designing a prepaid card for petrol bunk system and also petrol dispensing system using RFID technology. The system also supports with an additional feature of capturing the images of the vehicles passed by and also the people using camera and Raspberry Pi processor. Automation is the most frequently spelled term in the field of electronics. The hunger for automation brought many revolutions in the existing technologies. One among the technologies which had greater developments is RF communications. The result of this is the RFID cards which transmit a unique identification number. This number transmitted by the RFID can be read with the help of a RF reader. This project makes use of an onboard computer, which is commonly termed as Raspberry Pi processor. It acts as heart of the project. We make use of both these devices to construct a prepaid card for petrol station systems based on RFID. The concerned person of the vehicle should initially deposit money in the card initially. The RFID reader decodes the RFID tag which is with the vehicle and the amount is reduced from the prepaid card and this information is fed as input to Raspberry Pi processor. The processor reads this input and starts operating the dispensing motors until the required amount of petrol is dispensed into the vehicle. The dispensing system forms the output module and is interfaced to the same onboard computer. The system also enables with additional feature of capturing the images of the vehicles along with the surroundings. This feature can help the authorities or cops for searching thieves, theft vehicles etc.
