Uhf vehicle recognition equipment design

Vehicle recognition equipment or vehicle identification system is generally a fuel management system that provides solutions for fuel purchase of commercial vehicle fleets and fuel tracking of vehicles in fleets. This system was previously a system in which the control unit part was placed in the fuel pump and this unit provided control of the pump. With the expansion of the internet and the development of technology, the control of the pump has now started to be made using records on the databases. Thus, the control of the pump was included in the automation systems communicating with the database. On the other hand, vehicle information is transferred to the automation system by vehicle recognition equipment for querying the database. However, reading information from the vehicle at this stage is not healthy due to changing warehouse entries. Thus, vehicle recognition is not possible. In order to prevent all these, a vehicle identification system has been developed and electronic prototype has been realized in this thesis. With the electronic device developed, the problems experienced due to variable storage entrances are prevented. Thus, communication difficulties between the reader unit and the identification unit at the gun tip are overcome. In addition, communication with the identification unit could be achieved at distances that cannot be obtained with passive identification units. In this way, the problems of big vehicles that could not buy any fuel and other vehicles that had interruptions while buying fuel could be solved. For these operations, the identification unit is made operational with energy and communication with radio frequency is provided. For the reader unit to read the identification unit properly from different angles, a new monopoly antenna was designed, manufactured and included in the system. The system has been tried in many vehicles and it has been found that the problem of not being able to read is eliminated. Keywords: PCB antennas, RSSI, Vehicle identification system, UHF band,
