Indoor RFID Alignment System for Service Station

Nowadays, motorized vehicles are essential in our daily lives. Therefore, fuel supply services should be efficient and easily accessible. Fuel supplying may encounter some difficulties, such as queues, non-continuous availability of fuel, and fraud. The problems of long waiting queues and non-continuous availability of fuel can be solved by going to another near fuel station. However, fraud is a more serious issue that is more difficult to solve. We developed, by research, an intelligent system for fuel supply management to solve this problem. For safety reasons, we must avoid the risk of causing a spark in the fueling environment. In particular, an electric system close to the pump, the hose, or the vehicle fuel tank may be a risk. We opted for the RFID (Radio Frequency IDentification) technology and the use of passive tags, since semi-passive or active tags involve a battery, on one hand, and are significantly more expensive, on the other hand. A motorized vehicle is identified by a passive RFID tag; two other passive RFID tags are used for the fueling nozzle of each fuel pump. Our work consists of the design, by research, of the required system and focuses on the optimization of the topology of antennas and tags so that frauds are prevented. The technique is based on the alignment of tags.
