The present invention is at least one defect overcome described in the above-mentioned prior art, there is provided a kind of RFID Card Readers information filtering system
System, by filtering the RFID card information repeated, can accurate and effective read needed for RFID card information, avoid RFID card information dirty
Dye, improves the efficiency of RFID card.It can be widely used in various regional high frequency RFID card operational versions.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of RFID Card Readers information filtering system, bag
RFID reader, RFID filters, server are included, the RFID filters include front end filter and rear end filter；
Described front end filter reads in RFID information, eliminates the repetition values of RFID information, by data communication to rear
Hold filter；
The rear end filter matching filtering eliminates RFID information, and RFID information is sent to server.
Further, the front end filter includes information collection cache module, first timer, repetition values elimination mould
Block；
The information collects the information that cache module receives RFID reader, and it is fixed by first that information collects cache module
When device control transmit information to repetition values cancellation module；
The information collects cache module：The RFID card information read is collected, when caching is full, sends to repetition values and disappears
Except resume module；
The repetition values eliminate：Eliminate the repetition values in information cache；
The first timer：If information collects caching or information sends the time cached less than and more than setting,
Information is then sent into repetition values cancellation module.
Further, the rear end filter includes information table matching filtering module, information sends cache module, filtering
Information table maintenance module, second timer；
Described information table matching filtering module, which receives the information of repetition values cancellation module and is transmitted to information, sends caching mould
Block, the filtering information table maintenance module read information and send cache module information and feed back to information table matching filter module
Block, the information send cache module and will output information to server by second timer control；
The information table matching filtering：Value in information cache is matched with filter table, eliminates matched invalid value；
The information sends caching：The filtered value of information is collected, when caching is full, is sent to server；
The filtering information table is safeguarded：The data of caching are sent according to information, identify the value that should be filtered, renewal filtering
Table；
The second timer：If information collects caching or information sends the time cached less than and more than setting,
Then also by information sending server.
Compared with prior art, beneficial effect is：Realize the RFID card information for reading batch high frequency to filter, subtract
Lack the wasting of resources caused by system repeatedly reads identical RFID card, improve the efficiency that system gathers RFID card informations,
Improve the load of server batch processing RFID card information.Can accurate and effective read needed for RFID card information, avoid RFID
Card information pollutes, and improves the efficiency of RFID card.It can be widely used in various regional high frequency RFID card operational versions.
