Charging method of bus charging system based on rfid

Abstract

The invention discloses a RFID-based public transport charging system charging method; the public transport charging system comprises a RFID writer-reader, a control module, a display module, a storage module, a bus door status sensor and a RFID tag module; the RFID tag module comprises a plurality of RFID tags used for storing encrypted IDs, user names, and card balances; the RFID writer-reader is arranged in the bus and used for reading information of each RFID tag; the storage module is used for storing the coordinates of the RFID writer-reader in the bus and the bus space information; the bus door status sensor is used for sensing opening status of the bus door; the display module is used for displaying billing information; in application, the control module can decrypt, charge, encrypt and write the RFID tags of onboard passengers, and can use the display module to display the billing information. The RFID-based public transport charging system is simple in structure, convenient in usage, can actively deduct fares without wiping cards, thus improving on / off board efficiency.

Description

technical field [0001] The invention relates to the field of RFID application, in particular to a charging method of an RFID-based bus charging system. Background technique [0002] RFID is the abbreviation of Radio Frequency Identification, that is, radio frequency identification, which is a non-contact automatic identification technology. It automatically identifies the target object through radio frequency signals, and can quickly track items and exchange data. The identification work does not require manual intervention and can work in various harsh environments. RFID technology can identify high-speed moving objects and can identify multiple tags at the same time, and the operation is fast and convenient. RFID technology was born during World War II. It is the successor of traditional barcode technology, also known as "electronic tag". [0003] The basic working principle of RFID technology is not complicated: after the tag enters the magnetic field, it receives the r...

Problems solved by technology

3. Anti-pollution ability and durability, the carrier of traditional barcode is paper, so it is easy to be polluted, but RFID has strong resistance to substances such as water, oil and chemicals

6. The memory capacity of data is large. The capacity of one-dimensional barcode is 50Bytes, the maximum capacity of two-dimensional barcode can store 2 to 3000 characters, and the maximum capacity of RFID is several MegaBytes. With the development of memory carrier, the data capacity is also expanding continuously. trend

[0009] The existing bus fare system requires passengers to actively swipe their cards after getting on the bus. On the one hand, it takes time to take out the card and swipe the card itself, which delays the boarding time of the bus. Taking out and swiping the card is prone to collisions and falls
