Description

A kind of ultrahigh frequency RFID fast initialization EPC method

Technical field

The present invention relates to a kind of ultrahigh frequency RFID fast initialization EPC methods, belong to technical field of RFID.

Background technique

Currently, when in ultrahigh frequency electronic tag to client's hand, the area EPC is generally initialized as complete zero, client need by Different value is written in each label E PC, to distinguish different labels when making an inventory.And the initialization of ultrahigh-frequency tag mainly passes through read-write Device sends write command to label and completes, and tradition carries out EPC initialization flowchart as shown in figure 3, in actual mechanical process after making an inventory In, there are the following problems:

1) low efficiency: ultrahigh frequency electronic tag memory, in order to meet communication distance requirement, reduces memory read/write in design Power consumption, the content-length that once can be written into memory cannot be too long, long far below the content that EPC memory needs to initialize Degree, it is therefore desirable to which the data that will be initialized are written several times, this operation can consume client for quite a long time；

2) data are error-prone: since the length of EPC is longer, tag ram write-in needs biggish energy again, therefore data are first Error is easy during beginningization.

Summary of the invention

In view of the above existing problems in the prior art, the present invention provides a kind of ultrahigh frequency RFID fast initialization EPC method, Initialization efficiency can be improved, reduce error rate.

To achieve the goals above, a kind of ultrahigh frequency RFID fast initialization EPC method that the present invention uses, utilizes electronics Tag read device completes the initialization of EPC in multiple electronic tags, electronic tag reading and writing device include reader, host computer and Antenna, the ultrahigh frequency RFID fast initialization EPC method comprise the concrete steps that:

Step 1: reader sends radio-frequency carrier to multiple electronic tags by antenna, and electronic tag powers on；

Step 2: first making an inventory to one of electronic tag and enters safe condition, obtains tag read permission；

Step 3: reader sends command memory configuration-direct, successively opens TID copy function；

Step 4: reader sends command memory configuration-direct, and configuration needs the TID initial address replicated；

Step 5: reader sends command memory configuration-direct, and configuration needs the TID length replicated；

Step 6: reader sends command memory configuration-direct, and configuration needs for the TID content of duplication to be inserted into the position of EPC It sets；

Step 7: reader sends command memory configuration-direct, configures EPC Length information in host computer, defines label The total length of EPC；

Step 8: reader sends command memory configuration-direct, by the content for also needing to initialize in EPC write-in label storage Device；

Step 9: step 3 to step 8 completes whole EPC configuration process of made an inventory electronic tag, and reader continues to make an inventory Remaining electronic tag, and complete the initial work of EPC；

Wherein, the step of step 3 to step 8 can step in any combination, set-up procedure sequence.

The electronic tag includes radio-frequency front-end, AFE(analog front end), digital baseband processor and the memory of connection.

Compared with prior art, the present invention has the whole world according to ISO18000-6C agreement, each ultrahigh frequency electronic tag Unique encodings TID.Client only needs to enable simultaneously reasonable disposition function and TID all or part of the content is connected or is inserted into The area EPC, a part as EPC coding.Need to only EPC be written in remaining customized content by client, just complete the initialization of EPC Journey greatly reduces the initialization time of EPC.After label configures, it is dynamic to be automatically performed all or part of EPC initialization Make, does not need reader and send all write-in data commands to label again.To sum up, being initialized using this method, just Beginningization it is high-efficient, error rate is low.

Specific embodiment

The present invention will be further explained below with reference to the attached drawings.

As shown in Figure 1, Figure 2, shown in Fig. 4 and Fig. 5, a kind of ultrahigh frequency RFID fast initialization EPC method is read using electronic tag Write device completes the initialization of EPC in multiple electronic tags 4, and electronic tag reading and writing device includes reader 1, host computer 2 and day Line 3, which is characterized in that ultrahigh frequency RFID fast initialization EPC method comprises the concrete steps that:

Step 1 101: reader 1 sends radio-frequency carrier to multiple electronic tags 4 by antenna 3, and electronic tag 4 powers on；

Step 2 102: first making an inventory to one of electronic tag 4 and enters safe condition, obtains tag read permission；

Step 3 103: reader 1 sends command memory configuration-direct, successively opens TID copy function；

Step 4 104: reader 1 sends command memory configuration-direct, and configuration needs the TID initial address replicated；

Step 5 105: reader 1 sends command memory configuration-direct, and configuration needs the TID length replicated；

Step 6 106: reader 1 sends command memory configuration-direct, and configuration needs the TID content of duplication being inserted into EPC Position；

Step 7 107: reader 1 sends command memory configuration-direct, configures EPC Length information in host computer, definition mark Sign the total length of EPC；

Step 8 108: reader 1 sends command memory configuration-direct, and label is written in the content for also needing to initialize in EPC Memory；

Step 9 109: step 3 to step 8 completes whole EPC configuration process of made an inventory electronic tag 4, reader 1 after Continuous remaining electronic tag of making an inventory, and complete the initial work of EPC；

Wherein, the step of step 3 to step 8 can step in any combination, set-up procedure sequence.

Any combination step: certain several step or whole in optional three to eight step are configured.Such as it can only select Step 3: four, five, Step 3: five, seven or step 345678 and etc. configuration.

Set-up procedure sequence: three to eight do not need centainly to be arranged in order, can be with random order.Such as can carry out Step 5: Four, three or seven or six five-four-three of step 8 etc. configure.

Content schematic diagram after label fast initialization EPC is as shown in Figure 5.
