Abstract
The invention discloses a dual-frequency active label in 3.56MHz and 5.8GHz for avoiding stopping to charge. Wherein, it is formed by contact IC card read-write module, 13.56MHz read-write module, 5.8GHz radio frequency module, micro band antenna, control unit and power source manage unit; the contact IC card and 13.56MHz non-contact card are generally used in preset speedway to charge. The invention has the advantages that: it uses 5.8GHz remote RFID (radio frequency identification) technique, to realize charging without stopping vehicle, while said 3.56MHz/5.8GHz dual-frequency active electric charge label is compatible to the contact IC card and 13.56MHz non-contact card.
Description
Technical field
The present invention relates to a kind of 13.56MHz and 5.8GHz dual frequency active label that is applied to non-parking charge, adopt 5.8GHz far Distance RFID technology, support 13.56MHz non-contact card and Contact Type Ic Card that highway uses.
Background technology
Along with the quick increase of Freeway Development and automobile quantity, the expressway tol lcollection Study on Technology becomes the key areas of intelligent transportation research.In recent years, REID (RFID) obtains major progress, and the RFID label has begun to be applied to the expressway tol lcollection field at a distance, and the distance of reaction of these labels generally at several meters to tens meters, can be realized real non-parking charge.5.8GHz be the focus frequency range that present ETC uses.US and European has all been worked out the standard that is applied to ETC of 5.8GHz, and China ISO/TC204 technical committee view proposes the 5.8GHz frequency allocation is given the junction service in ITS field, comprising the ETC system.And the ETC test is carried out in approval on the 5.8GHZ frequency range.
The highway tolling system majority adopts the modes of Contact Type Ic Card and 13.56MHz non-contact card at present, 13.56MHz non-contact card particularly,, low cost and other advantages easy to operate with it obtained to popularize, and the non-contact card quantity tool of having provided is big, and relevant background devices is also more complete.As how lower cost existing contact card and non-contact card Fare Collection System being carried out the transition to the 5.8GHzETC system is a current big demand, supports the 5.8GHzETC dual frequency active label of contact card and non-contact card to adapt to just that these needs propose.
Summary of the invention
The objective of the invention is to: the 13.56MHz non-contact card of the existing highway tolling system of a kind of compatibility and the remote ETC dual-frequency label of 5.8GHz of Contact Type Ic Card are provided.
Technical scheme of the present invention is: a kind of 13.56MHz and 5.8GHz double frequency RFID electronic charging label, adopt 5.8GHz far Distance RFID technology, 13.56MHz non-contact card and Contact Type Ic Card that compatible highway at present uses.It is made up of several parts such as Contact Type Ic Card module for reading and writing, 13.56MHz module for reading and writing, 5.8GHz radio-frequency module, microstrip antenna, control module and power managements.13.56MHz non-contact card or Contact Type Ic Card insert in the dual-frequency label by draw-in groove, dual-frequency label is finished and non-contact card and the information interaction that contacts card by 13.56MHz module and Contact Type Ic Card module for reading and writing, and the 5.8GHz radio-frequency module is finished the radio communication with read write line.
Advantage of the present invention is: the present invention has adopted 5.8GHz far Distance RFID technology, has realized the non-parking charge of highway, the simultaneously compatible Contact Type Ic Card and the 13.56MHz non-contact card of present use.

Embodiment
Below the present invention is done and describe in further detail.Referring to Fig. 2, the dual-frequency label that the present invention relates to is made up of several parts such as Contact Type Ic Card module for reading and writing, 13.56MHz module for reading and writing, 5.8GHz radio-frequency module, microstrip antenna, control module and power managements.The present invention comprises 13.56MHz and two high-frequency models of 5.8GHz, so be called dual-frequency label.Non-contact card and Contact Type Ic Card are two kinds of rate cards that present highway user uses, card inserts dual-frequency label by draw-in groove, dual-frequency label is supported existing two kinds of rate cards by 13.56MHz module for reading and writing and Contact Type Ic Card module for reading and writing and control module, and the 5.8GHz radio-frequency module has constituted the communication channel with read write line.Power management module is according to the duty of label, and the part of module of adjustment label changes battery saving mode over to or wakes up from battery saving mode, to reduce the power consumption of whole label.
Implement main points of the present invention and be dual-frequency label and pass through 13.56MHz module for reading and writing and Contact Type Ic Card module for reading and writing and control module and support existing two kinds of rate cards, adopt 5.8GHz far Distance RFID technology to realize non-parking charge simultaneously.
Fig. 1 is the synoptic diagram of long-range radio-frequency identification ETC system.Long-range radio-frequency is discerned the ETC system mainly by the RFID vehicle identification system, compositions such as background manage software and other auxiliary equipment.Vehicle identification system comprises vehicle-mounted RFID label, and utility appliance such as read write line unit and ground induction coil are formed.When vehicle enters the reach of reading and writing device antenna, at first trigger the ground induction coil on the road surface, PC receives that starting read write line behind the signal of ground induction coil seeks the RFID label, if vehicle has carried legal RFID label, then label and read write line are by the radiofrequency signal exchange message, the vehicle dispense with parking just can be finished the authentication and the operation of paying dues, and passes through charge station.If vehicle does not carry the RFID label or is illegal label, then will be blocked.
More than introduced the composition module of the dual-frequency label that the present invention relates to, the specific implementation form of this invention, may have multiple variation as the physical circuit of each module, the form of antenna, all belong in scope of the present invention as the 5.8GHzRFID label of supporting 13.56MHz non-contact card and Contact Type Ic Card.
