Embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment will be carried out clear, intactly description.
Referring to Fig. 1, be the circuit module figure of the active RFID card sender that provides of the utility model embodiment.
The active RFID card sender that present embodiment provides comprises: processor 1, RF transceiver 2, PCB directional antenna 3 and power module 5.Processor 1 is connected with RF transceiver 2, and RF transceiver 2 is connected with PCB directional antenna 3.PCB directional antenna 3 is a built-in aerial, and the below of antenna is provided with the reflection aluminium sheet; And has absorbing material with the back of reflection aluminium sheet around the antenna.
The active RFID card sender also comprises shell, shows the read area that is useful on read write tag at the shell subscript; This read area is positioned at the top of PCB directional antenna 3.
Further, as shown in Figure 1, the active RFID card sender (hereinafter to be referred as card sender) that present embodiment provides also comprises the USB interface 6 that is used to transmit data and power supply, and this USB interface 6 is connected with processor 1.During practical implementation, card sender with after outside computing machine is connected, can transmit data through USB interface 6 through USB passage and computing machine, and the acquisition working power.
Optional, as shown in Figure 1, card sender also comprises tag activation module 4, this tag activation module 4 is connected with processor 1.
Need to prove, when card sender the label that will read, be that this card sender need be provided with the tag activation module, sends active information to active label when adopting the timing wake-up radio frequency to trigger the active label of transmit mechanism.And the label that will read when card sender institute is when adopting the label of the uncontrolled unidirectional transmit mechanism of timing wake-up, and this card sender need not to be provided with the tag activation module, only need 1 the tunnel with the RF transceiver of label correspondence frequency, be used to detect active label.
One preferred embodiment in, as shown in Figure 1, card sender also comprises pilot lamp 7, this pilot lamp 7 is connected with processor 1.During practical implementation, after card sender is connected to computing machine through USB interface 6, obtain power supply, beginning initialization card sender, pilot lamp 7 flickers this moment from computing machine.After initialization finishes, pilot lamp 7 Chang Liang.
Another preferred embodiment in, as shown in Figure 1, card sender also comprises hummer 8, this hummer 8 is connected with processor 1.During practical implementation, card sender whenever reads a label, and hummer 8 sends prompt tone.The time that hummer 8 sounding continue can be set, and also can forbid sounding.
Referring to Fig. 2, be the structural representation of the active RFID card sender that provides of the utility model embodiment.
The PCB directional antenna of active RFID card sender is a built-in aerial, and the below of antenna is provided with reflection aluminium sheet 9; With absorbing material, annular region 10 as shown in Figure 2 is an absorbing material around the antenna.And the back of reflection aluminium sheet 9 is also with absorbing material.
As shown in Figure 2, card sender also comprises shell 11, and on shell 11, indicating has read area, this read area to be positioned at PCB directional antenna top.Optional, can USB interface 6, pilot lamp 7 and hummer 8 be installed on the shell 11, conveniently use and observe the duty of card sender.
The built-in PCB directional antenna of card sender possesses less main lobe width, and the signal power of transmission is little, and has good directionality.In addition, the antenna bottom has the good aluminium sheet of reflecting properties, and around the antenna and the aluminium sheet back side has guaranteed that also with absorbing material card sender can only receive or send the signal of assigned direction.During practical implementation, card sender can only be read and write the label that is placed on read area, and reads less than the outer label of read area, has realized card sender reading specify labels.
The principle of work of the active RFID card sender that provides in the face of present embodiment is down described in detail.
When card sender the label that will read be when adopting the timing wake-up radio frequency to trigger the active label of transmit mechanism; The RF transceiver of card sender is in lasting accepting state; Because the effect of built-in PCB directional antenna; The radiofrequency signal of having only the label in the read area to send could be received by card sender, and the radiofrequency signal that the outer label of read area sends can not received by card sender.
When card sender the label that will read be that card sender also needs the label allocation active module when adopting the label of the controlled unidirectional transmit mechanism of timing wake-up, send active information to label, trigger label and send radiofrequency signal.Because the effect of built-in PCB directional antenna; The radiofrequency signal of having only the label in the read area to send could be received by card sender; Even and the radiofrequency signal that the outer label of read area sends after being activated also can not received by card sender; Same realization card sender reads label one by one, after the card sender success reading tag, and the hummer sounding of card sender and pilot lamp flicker indication.If the card sender reading tag is unsuccessful, only need remove label from the card sender reader after, wait for the reader that once more label was placed on card sender in 1 second.
After card sender passes through USB interface and computing machine is connected, can send order to card sender, start the information that card sender reception label sends through computing machine.After card sender receives label information, send to computing machine through USB interface immediately.Card sender also can be in accepting state always after powering on, continue the information of detecting from label, is transmitted to computing machine after receiving immediately.For the active RFID tag of supporting write operation, card sender can also receive the information from computing machine, and information is write label.
In an application scenarios, the active RFID application system comprises active label, reader, card sender and computing machine.Before active label comes into operation, seriatim active label is placed on the read area of card sender, obtain the active label sequence number seriatim by card sender.Card sender sends to computing machine with tag serial number, accomplishes tag serial number and corresponding attribute (for example user profile, Item Information etc.) on computers and binds, and deposit database in, thereby accomplish the hair fastener function.Present embodiment adopts card sender to read the active label sequence number one by one, no longer needs manual input label sequence number, has improved hair fastener speed greatly, and has avoided the mistake of manual input.
In the Another application scene, in the production run of active RFID tag, tag serial number is cured in the inner storer of label.After accomplishing the tag package completion, need go out identifier at the shell surface marking, to distinguish each label, this identifier is corresponding one by one with tag serial number.The card sender that adopts present embodiment to provide; Can be after tag package be accomplished; Read the sequence number of the built-in curing of each label one by one, thereby easily go out corresponding identifier at the shell surface marking, whether the tag serial number of perhaps checking card sender to read is corresponding with tag identification number; Improve production efficiency greatly, also avoided taking place the sequence number of the built-in curing of label and the inconsistent situation of identifier that the label case surface indicates.
The above is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also are regarded as the protection domain of the utility model.
