The RFID information reading technology comprises an RFID card reader and RFID tag cards. The RFID information reading technology is characterized in that the RFID card reader is provided with an RF chip which contains information of channels needing to be read; and the RFID tag cards have at least one channel, and each RFID tag card is on one channel. Through the way of polling, the RFID information reading technology is compatible with the existing various tag cards with the minimal cost, the RFID information reading technology is dynamically compatible with the reading of data in various types of RFID tag cards, and the RFID information reading technology has the beneficial effects of cost saving, good compatibility and wide range of application.
Description
Technical field
The present invention relates to RFID and intercept technical field, particularly belong to a kind of RFID information reading technology.
Background technology
RFID card reader in existing RFID information reading technology, can only receive the signal of single channel, if will receive the data of multiple channel, then need multiple card reader, cost is high, is unfavorable for the compatible various types of label cards using different channels.
Summary of the invention
Namely object of the present invention is to provide a kind of RFID information reading technology, can receive the signal of multiple channel simultaneously, to reach cost-saving, facilitates the object of compatible all kinds label card.
RFID information provided by the present invention reads technology, and comprise RFID card reader and RFID label tag card, it is characterized in that, described RFID card reader has RF chip, and above-mentioned RF chip is provided with the information needing to read channel; Described RFID label tag card has a channel at least, and each RFID label tag is positioned on a channel.Wherein, the interval time that RFID label tag card sends label information is greater than the interval time that RFID card reader is intercepted.
RFID card reader is by arranging RF chip parameter, RFID card reader is made to be positioned on different channels, the RFID label tag card being positioned at each signal channel constantly sends label information, RFID card reader reads type and the parameter of RFID label tag card as required, and pass through remote technology, realize the dynamic conditioning to RF chip parameter in RFID card reader, thus realize RFID card reader intercepting one by one multiple signal channel.
When RFID card reader intercepts signal channel 1, if channel 1 has data, can upload the data to external unit, if countless certificate on channel 1, RFID card reader can continue to intercept signal channel 2; If signal channel 2 has data, RFID card reader can by the data upload on channel 2 to external unit, if channel 2 does not have data, RFID card reader can continue to intercept signal channel 3; Repeat above to intercept behavior, and upload the data to external unit when there being data, countless according to time continue intercepting of next channel.
RFID information provided by the present invention reads technology, RFID card reader can receive the signal of multiple channel simultaneously, by the mode of poll, with the compatible existing all kinds of label card of minimum cost, achieve the reading of dynamic compatible polytype RFID label tag card data, have cost-saving, the good effect of compatible good and applied range.
Accompanying drawing explanation
Accompanying drawing part discloses specific embodiments of the invention, wherein,
Fig. 1 is workflow diagram of the present invention.
Embodiment
As shown in the figure, RFID information provided by the present invention reads technology, comprises RFID card reader and RFID label tag card.Wherein, described RFID label tag jig has channel 1, channel 2 ... the N number of channel of channel, each RFID label tag is positioned on a channel; Described RFID card reader is provided with RF chip, and RF chip is provided with the information needing to read channel.RFID card reader is by arranging RF chip parameter, RFID card reader is made to be positioned on different channels, the RFID label tag card being positioned at each signal channel constantly sends label information, RFID card reader can read type and the parameter of RFID label tag card as required, and pass through remote technology, the parameter of dynamic conditioning RFID card reader, the data of RFID card reader to the RFID label tag card of different channels are intercepted one by one, thus realizes the reading of the dynamic compatible polytype RFID label tag card data of RFID card reader.
It is 3 times per second in the present embodiment that above-mentioned label information sends the frequency, but is not limited only to 3 times, can set according to actual needs.In addition, the interval time that RFID label tag card sends label information is greater than the interval time that RFID card reader is intercepted.
Principle of work: when RFID card reader intercepts signal channel 1, if channel 1 has data, external unit can be upload the data to, if countless certificate on channel 1, RFID card reader can continue to intercept signal channel 2, if signal channel 2 has data, RFID card reader can by the data upload on channel 2 to external unit, if channel 2 does not have data, RFID card reader can continue to intercept signal channel 3, repeat above to intercept behavior, and upload the data to external unit when there being data, countless according to time continue intercepting of next channel.
In addition, RFID card reader is intercepting the data on different channels, upload the data in the process of external unit, and RFID card reader intercepts the number of signal channel, according to actual needs, sets in the RF chip of RFID card reader.
The present invention is in the Application Example in intelligent anti-theft field: at the RFID label tag card needing to carry out antitheft various vehicles being worn different numbering or address, RFID label tag card sends signal according to setting, the RFID card reader information of carrying out in certain area is intercepted, by intercepting the information such as numbering, position, owner obtained with RFID label tag card associated vehicles.If after monitoring a period of time, there is the FRID label information of vehicle during beginning always, if suddenly without the information of this car, illustrate that this car may be lost, then the managerial personnel in management and control region need be paid attention to, and notify that end user carries out confirming or managerial personnel in person carry out scene and confirm, thus avoid the generation of stealing hidden danger, or controlled at thievery early period of origination, reduce loss.
The Application Example of the present invention in Intelligent campus is built: the pupil in campus wears the RFID label tag card of different numbering or address, and RFID label tag card sends signal according to setting, and carries out intercepting of data by RFID card reader.If the signal channel of setting is 10, result only listens to the data of 9 signal channels, then represent a pupil not within the scope of nurse, and campus administration personnel need carry out confirming or checking at once, thus avoid the generation of unsafe incidents, or carry out corresponding measure in time at event early period of origination.
In sum, it is low that RFID information reading technology provided by the present invention has cost, and the information that the multiple RFID label tag card that can read unlike signal channel sends is compatible good, can be widely used in multiple field.
Claims (2)
1. RFID information reads a technology, and it is characterized in that, comprise RFID card reader and RFID label tag, it is characterized in that, described RFID card reader has RF chip, and above-mentioned RF chip is provided with the information needing to read channel; Described RFID label tag card has a channel at least, and each RFID label tag is positioned on a channel;
Wherein, RFID card reader is by arranging RF chip parameter, RFID card reader is made to be positioned on different channels, the RFID label tag card being positioned at each signal channel constantly sends label information, RFID card reader reads type and the parameter of RFID label tag card as required, and by remote technology, realize the dynamic conditioning to RF chip parameter in RFID card reader, thus realize RFID card reader intercepting one by one multiple signal channel;
