Abstract
The invention provides a far-distance active remote radio frequency tag card which consists essentially of a controller, a timer, a RAM/ROM, a UHF transceiver, a LF field intensity detection circuit, an antenna and a power supply. The invention further introduces a set of perfect activation dormant conversion mechanism to effectively solve the problem of the working time of a battery, the radio frequency tag reports the current information to a reader and writer and then enters the dormant state, if the radio frequency tag is triggered by an external trigger or the timer, the radio frequency tag immediately enters the working state to communicate with the reader and writer by a UHF wireless interface, thus greatly improving the power saving application. As the radio frequency tag card does not have the bottleneck on the power supply power and can be made into the cards with different shapes according to the needs of the practical application, the radio frequency tag card has the advantages of far identification distance, high identification accuracy and so on. Thus the far-distance active remote radio frequency tag card has the advantages of reasonable structure, easy implementation, reasonable cost, wide application and so on.
Description
A kind of distant range active remote radio frequency label card.Relate in particular to automatic identification and non-contact data switching technology.
Technical field:
Automatic electronic identification and non-contact data exchange.
Background technology:
REID is an automatic identification technology that begins to move to maturity from the eighties.Because the maturation of large scale integrated circuit technology, the volume of radio-frequency recognition system dwindles greatly, and this technology enters into the stage of practicability.REID utilizes RF-wise to carry out the noncontact two-way communication, thereby reaches the purpose of identification and swap data.Different with the same period or early stage contact recognition technology is, just need not contact between the radio-frequency card of rfid system and the read write line and can finish identification, so it is adapted to widely in the occasion, but its price is higher, is not suitable for working under rugged surroundings.Because the passive RF card does not contain battery, utilize the electromagnetic wave of read write line emission that energy is provided, but its transmitting range is restricted, generally is tens centimetres, and needs the emissive power of read write line big again.By contrast, passive RF is being restricted aspect reading distance and the adaptation object of which movement speed.Therefore the bright development of this law just seems very necessary.
Summary of the invention:
Distant range active remote radio frequency label card critical piece of the present invention by: controller, timer, RAM/ROM, UHF transceiver, LF field intensity testing circuit, antenna and power supply are formed jointly.In order effectively to solve the problem of battery working time, the present invention introduces perfect activation, the dormancy of a cover again and changes the mechanism, radio-frequency (RF) tag promptly enters dormant state after read write line has reported current information, if be subjected to that extraneous trigger triggers or timer trigger after enter duty at once, by UHF wave point and read write line communication, improved its economize on electricity greatly and used.Because active radio frequency label card does not exist the bottleneck of output power aspect, characteristics such as decipherment distance is far away so it has, recognition accuracy height.Therefore, be one and have rational in infrastructurely, easy to implement that cost is reasonable, characteristics such as be widely used.
Description of drawings:
Distant range active remote radio frequency label card accompanying drawing of the present invention is a block diagram of the present invention, receiving antenna among the figure (1), LF field intensity testing circuit (2) amplifying circuit (3), circuit (6), modulator (7) antenna (8) and power supply (9) are prepared in control module (4), RAM/ROM storer (5), emission, the common composition.Wherein wake-up circuit is provided with in controller.
Embodiment:
The enforcement of distant range active remote radio frequency label card of the present invention is to use the design proposal of conventional integrated circuit, realized repertoire of the present invention at the finished product that uses conventional discrete circuit to be overlapped to form, and transmitting range is greater than 100m.The requirement of each circuit among the figure according to integrated circuit designed, is manufactured in the integrated circuit, make the card of various styles then as required.Both constituted the present invention.
In order to further specify its implementation method, here be further described with regard to its active remote radio frequency label card that uses discrete component and integrated circuit to mix overlap joint: the present invention has adopted superregenerative receiving circuit, reduced material cost greatly, receiving circuit adopts the working method of intermittent power supply to reduce stand-by power consumption simultaneously.On the basis of existing components and parts, according to the production method of conventional electrical product, circuit production is become a high frequency active remote radio frequency label circuit, reinstall in the card.Promptly constitute the present invention.Simultaneously also can be made into integrated circuit according to the principle of the invention.With all electronic devices and components, integrated circuit or complete chip of whole integrated one-tenth, at last, make the card of different shape according to the needs of practical application.Just constituted distant range active remote radio frequency label card of the present invention.
