Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The present invention provides various embodiments, specifically, please referring to Fig.1-Fig. 2 the first embodiment of the invention, provides one kind
Based on the collision-proof method of hyperfrequency rfid transponders, include the following steps,
A1, reader send the first identification instruction to transponder；Wherein, the transponder of the first identification of response instruction generates the
One random number；The digit of random number is 2；
In this step, it should be appreciated that reader can be the device that existing rfid readers etc. have identification function
Part；Transponder can be that electronic tag etc. can be by the device of radio frequency identification.
Random number uses system, such as binary system etc.；

The transponder of identification instruction " Request (00) " generates the second random number；The digit of second random number is more than 1；TagA、TagB、
The second identification instruction " Request (00) " of TagG responses；The second random number of TagA, TagG are the second random number of 01, TagB
It is 11；
It is worth noting that after TagA-TagG generates random number, own register can be written in respective random number；Base
In this, when reader sends the second identification instruction " Request (00) ", TagA, TagB, TagG can respond the second identification and refer to
It enables.
A311, reader receive the third random number of response third identification instruction passback in each time slot and detect third
Collision time slot in the response time slot of random number；
Please refer to Fig. 2, reader receives the of response the second identification instruction " Request (00) " passback in each time slot
Two random numbers and the collision time slot responded in time slot for detecting the second random number；Detection obtains the response of the second random number of TagB
Time slot is that non-collision time slot TagB identifies that successfully the register of itself is written in its second random parameter " 11 " by TagB, at this time
The register storage content of TagB is " 0011 "；The response time slot of the second random number of TagA, TagG is collision time slot；
Reader complete to all second random numbers response time slot detection after, by for collide time slot response when
Second random number of gap responds the response sequential storage of time slot by it and prelists parameter to second, specifically can refer to the parts T2 in Fig. 2；
Second random number of storehouse 2 is respectively written into each stack layer of storehouse 1 by subsequent reader, obtains 0001,10；Reader
The random number of the most bottom stack of storehouse 1 after extraction write-in is instructed with the first identification of update, generates updated third identification again
Instruction, " Request (0001) ", reader send third identification instruction to transponder, TagA, TagG respond and generate third with
Machine number, wherein the third random number of TagA is that the third random number of 01, TagG is the third random parameter of 11, TagA and TagG
Collision time slot be non-collision time slot, TagA, TagG are identified successfully；Itself is written in its third random parameter " 00 " by TagA
