In the first transmission power, third transmission power is different from the second transmission power, and the first amount threshold is different from the second amount threshold.
It when there is multiple RFID label tags to need to inquire, can inquire in batches, each batch chooses one or more RFID
Label.Preferably, only choosing one, especially when inquiring weak label, only choose a weak label every time, avoid in each inquiry
Influence of other signals to weak label, to increase the query rate of weak label.The weak label refer to, due to position or property itself
Energy reason, the weaker RFID label tag of signal responding ability.
In the embodiment of above inquiry RFID label tag, the first kind message can be RN16, second class
Type message can be EPC (product code) information.
As shown in Fig. 2, for according to the flow chart of the RFID label tag checking method of one embodiment of the invention.Specifically include with
Lower step:
Step S100, all RFID label tags into Intelligent cargo cabinet are initiated to make an inventory for the first time.For identifying in Intelligent cargo cabinet
The FRID label informations of commodity is it is known that in the memory being for example stored in Intelligent cargo cabinet, or is stored in remote server.
When RFID label tag of the Intelligent cargo cabinet in cabinet of making an inventory, the processor control reader of Intelligent cargo cabinet issues wireless signal, uploads
It makes an inventory instruction.RFID tag in cabinet responds instruction therein of making an inventory to the wireless signal, sends its label letter
Breath, predominantly EPC information, i.e. product code, when receiving the EPC information, determination is made an inventory to the RFID label tag.
Step S200 determines the RFID label tag that do not make an inventory.After making an inventory for the first time, the mark that will currently make an inventory
Label information is compared with the label information before making an inventory, and can determine the RFID label tag that do not make an inventory.For example, counter before making an inventory
Inside share 100 RFID label tag tag1, tag2, tag3 ... tag100, by make an inventory to obtain for the first time tag1, tag2,
Tag3 ... tag90, it is found that not having there are also 10 RFID label tag tag91, tag92, tag93 ... tag100 after comparison
Have made an inventory to.Thus, by making an inventory for the first time, the RFID label tag in counter is divided into two set: not being made an inventory
RFID label tag is first set, and the RFID label tag made an inventory is second set.
Step S300 carries out secondary make an inventory using the method for inquiry tag for the RFID label tag in first set.At this
In embodiment, the RFID label tag in first set is usually weak label, and due to position or performance reason itself, signal respond
Ability is weaker than the RFID label tag made an inventory for the first time.When carrying out secondary make an inventory, chaotic or signal interference, is looked into every time in order to prevent
It askes and only inquires a RFID label tag.Wherein, the process for inquiring a RFID label tag is as shown in Figure 3:
Step S301 adjusts the transmission power of reader.Since the RFID label tag that part can not make an inventory is because of its position
Continuous wave irradiation cannot be received and can not activate by the reasons such as setting, and cannot respond instruction of making an inventory, thus in secondary make an inventory, in order to
The transmission power tune of reader must be greater than transmitting function used when making an inventory for the first time by the responding ability that can be improved RFID label tag
Rate.It however, reflection power is also big if transmission power is too big, will cause that receive the bit error rate too high, can not make an inventory to RFID
Label.Thus, a suitable transmission power can be determined by repetition test.
Step S302, selection need the RFID label tag made an inventory.It is chaotic in order to prevent, one is only selected in the present embodiment
RFID label tag.Specifically, which RFID the setting of the assert flag bit in being instructed by select selects mark to realize
The purpose of label.
The RFID label tag of step S303, Xiang Xuanzhong send query instruction, and receive the occasional password of RFID label tag return
RN16, in the present embodiment, RN16 is as the first kind message.Query instruction is used as inquiry instruction.As shown in figure 4, being
Signal when reader is interacted with RFID label tag sends schematic diagram.The message that the first behavior reader in figure is sent, the second row
The message returned for RFID label tag.Reader send message in include select instruct, then repeat send query instruction and
NAK instruction.It include RN16 in the message that RFID label tag returns.For normal, when RFID label tag receives query instruction every time,
RN16 will be sent as occasional password to reader.But due to being blocked etc. component, if RFID label tag does not receive
It is instructed to query, then will not send RN16.
Step S304 judges whether the query instruction for having had sent setting number, such as 50 times, if query instruction
Transmission times has had reached setting number, goes to step S305, if the transmission times of query instruction does not reach setting time
Number, return step S303 continue to send query instruction.
Step S305, statistics receive the number of RN16.
Whether step S306, the quantity that judgement receives RN16 have reached amount threshold, such as 5.If receiving RN16's
Quantity is greater than or equal to 5, then inquires the RFID label tag in step S309 confirmation and terminate to inquire the RFID label tag
Process；If not reaching 5, step S307 is gone to.
Step S307 judges whether to reach scheduled inquiry times, such as 10 times.If it is not, step S301 is gone to, weight
New adjustment transmission power, carries out inquiry next time.If having had reached inquiry times, that is, transmission power 10 is changed
It is secondary, 10 inquiries have been carried out, then have not inquired the RFID label tag in step S308 confirmation.
Step S400, it is determined whether the RFID label tag in all first sets is all inquired, if all inquired
It is over, then completes this and make an inventory；If do not inquired there are also RFID label tag, return step S300 continues to inquire.
In the present embodiment, those are caused to receive the weak RFID label tag of signal due to position, tag performance etc.,
Normally make an inventory make an inventory in treatment process less than when, using the method for inquiry, no longer using the EPC information of RFID label tag as being
The no judgment criteria made an inventory, but to receive RN16 of the quantity greater than amount threshold as judgment criteria.Due to EPC information
Data volume (usually 64 byte) is much larger than the data volume (2 byte) of RN16, thus, embodiment improves efficiency of making an inventory.Its
In, in order to guarantee accuracy rate that the present embodiment is made an inventory, multiple query instruction is sent in the present embodiment, it such as 50 times, certainly, can also
To be 20 times, 30 times, 80 inferior, usual any one number that can use within 20-100 times.The present embodiment, which is also provided with, to be used for
Judge whether to receive the amount threshold of RN16,5 as elucidated before.For example, if having sent 50 query instructions,
The quantity for wherein having received the RN16 of return is at least 5, then can determine that the RFID label tag is implicitly present in.
As shown in figure 5, the schematic diagram of the Intelligent cargo cabinet for one embodiment of the invention.The Intelligent cargo cabinet includes
RFID label tag check system and multiple RFID label tags 300.Wherein, the RFID label tag check system includes processor 100 and reads
Device 200 is write, processor 100 is connected with the reader 200, is configured to choose one or more RFID label tags, indicates institute
