Abstract:
Radio Frequency Identification (RFID) is an auto identification technology which uses Radio Frequencies (between 30 kHz and 2.5GHz) to identify objects remotely. The paper describes a system which does the job of detecting, billing and accounting for vehicles as they pass through a tollgate using RFID as the identification technology. In the design, a frequency of 928MHz is used as it is in the Industrial Scientific and Medical (ISM) band. The system is a great investment in the transport industry. It reduces the common hustles in accounting for the movement of goods from point to point. The design can be further developed to aid the satellite surveillance systems once all toll gates are networked. An RFID tag is programmed with information in the form of an Electronic Product Code (EPC), which can be read over a considerable distance so that its contents identify the vehicle and enhance a transaction to be undertaken with respect to the specific tag identity taking advantage of radio frequencies ability to travel longer ranges with better data capacities and high speed attained with maximum accuracy. The design has been implemented as a miniaturized prototype.
Objective:
When the vehicle is going to enter into the toll plaza, the first aim is to detect the type & no. of the vehicle. For that purpose, it has to first pass through the IR transmitter - receiver gate.Then we have here the RFID system. In this system the tag is detected by the RFID reader & the data is matched withthe database provided at every toll booth. When further vehicle is going towards the Load cell plate it has to passthrough the IR transmitter - receiver gate.The RFID data is stored on tags which respond to the reader by transforming the energy of radio frequency queries from the reader (or transceiver), and sending back the information they enclose. A computer hosting a specific RFID application pilots the reader and processes the data it sends. The ability of RFID to read objects in motion and out of the line-of-sight is its major advantage. The tags can be read under harsh conditions of temperature, chemicals and high pressure.
RFID has the potential to change an organization’s ability to get real time information on the location of asserting and even personnel. The use of RFID technology reduces operational costs by reducing the need for human operators in systems that collect information and revenue collection. In manufacturing, a tagged product or part can be traced and this gives better visibility and the bottlenecks in automated manufacturing processes can be easily identified.The technology can also be used in toll collection at toll gates and this enables the tracking of vehicles as well as the goods they carry, in real time. Location tests prove that RFID is the best technology for tracking items in motion. The technology enables remote storage and retrieval of data and this is why developments towards wireless identification point towards low-bandwidth systems like RFID
