Description
Technical field
The present invention relates to electronic communication field, RFID electronic tag, specifically the data handling system in the intensive layout environment of a kind of RFID tag can realize information reading and data handling system in transformer station's storehouse of the intensive layout of RFID tag.
Technical background
RFID (radio-frequency (RF) identification) system is generally comprised of RFID reader and transponder (being RFID label).Between RFID reader and transponder, by electromagnetic field, communicate.According to the difference of communication frequency between RFID reader and transponder (as 125KHz, 13.56MHz, 900MHz etc.), the communication distance between RFID reader and transponder is also different.In the situation that transponder does not use external power supply as battery (being passive label), general low frequency RF ID system communication distance is at several centimetres, and high-frequency RF ID system communication distance can reach 1-2 rice, and ultrahigh frequency RFID system communication distance can reach 10 meter level left and right.If transponder uses external power supply, it understands fartherly with the communication distance of RFID reader, can reach tens meters to km rank.
RFID technology allows for RFID transponder and specifies unique coding, so that RFID reader identifies uniquely this transponder when carrying out read operation.By setting up relation one to one between the object that RFID transponder and it are adhered to, RFID reader is identified this transponder and has been equivalent to identify the object that this transponder adheres to.RFID technology is often applied to the management of the article such as equipment and assets (as valuables such as relays).In stock control, generally use passive high frequency or ultra-high frequency RFID label, use active RFID tag will increase handling cost.Compare use bar code, this communication of RFID is non-contacting, without optical visible, and reading tag information quickly and easily.When count of stock, managerial personnel needn't use RFID reader just can once read a large amount of label informations to each article one one scan being managed, and greatly reduce managerial personnel's labour intensity.
As mentioned above, RFID label, when for stock control, has often been concentrated a large amount of RFID labels in a certain region.Conventionally RFID reader sends after reading tag instruction, RFID reader will be received the return signal of all labels in its signal coverage areas simultaneously, generally, utilizes anticollision technology, constantly screening, finally obtains the mutual information exchange with the target labels of expecting.Sometimes, managerial personnel have seen the RFID label on stock article, want to read the information in this label, use in conventional method situation, and reader still can read the return signal of a plurality of labels.
