Embodiment 3
A kind of rove chain transmission retroactive method based on RFID, its step are as follows:
Step 1: RFID electronic label 4 is set in rove chain 1, and each default route is at least arranged one for reading
Optoelectronic switch 6 is detected with the reader 3 and chain of the ID data of output RFID electronic label 4, and is provided with and is read for receiving
The programmable logic controller (PLC) of the data of the sending of device 3 is write, chain detects optoelectronic switch 6 and is responsible for reader in detection current slot
3 regions whether there is chain 1；
Step 2: the chain 1 of rove is along different default route walking to next process, when chain 1 advances to chain inspection
It surveys at optoelectronic switch 6, chain detection optoelectronic switch 6 exports in corresponding control signal to programmable logic controller (PLC), may be programmed
Logic controller sends the ID data of the electronic tag 4 stored in reader 3 in memory and database；
Step 3: control signal is had issued to programmable logic controller (PLC) when chain detects optoelectronic switch 6, but reader 3
Corresponding 4 data of RFID electronic label are not returned, then programmable logic controller (PLC) issues the missing of RFID electronic label 4 and either damages
Bad, i.e., RFID electronic label 4 is to lose label, and alarm by alarm module；
Step 4: when the yarn on rove chain 1 has found problem in subsequent use, according to RFID electricity on problem chain 1
The related data stored in the ID data and programmable logic controller (PLC) of subtab 4 matches, and searches the responsible batch that produces and asks
Specific location of the board and chain 1 relevant to the board of topic yarn in subsequent processing.
In actual production, it is also possible to occur there is no the either RFID electronic label of RFID electronic label 4 on chain 1
The case where 4 damage, at this time if still using chain transmission traceability system and method in Examples 1 and 2 equally cannot be real
The positioning of existing problem board and the interception of problem yarn.The present embodiment is equipped with a chain detection on each reader 3
Optoelectronic switch 6, chain detection optoelectronic switch 6 are able to detect at its ray position with the presence or absence of chain 1, as shown in Figure 1.This implementation
Example can effectively avoid the case where causing loss of data due to electronic tag 4 is lacked and either damaged, and can be accurate
Positioning failure board and timely intercept problems yarn guarantee the normal operation of chain transmission traceability system.
It loses the fast algorithm of detecting of label: assuming that there are L readers 3 in system, being denoted as R={ R1, R2 ..., R
L }, these readers cover entire monitoring area.The fast algorithm of detecting of label is lost based on the observation that if one
Label is to lose label, then the label does not appear in the read range of any reader 3.Otherwise, if a label is
Label is not lost, which should appear in the read range of at least one reader 3.
Programmable logic controller (PLC) judges electronic tag 1 for the method for losing label are as follows: programmable logic controller (PLC) passes through
Detect RFID electronic label 4 in all 3 read ranges of reader there are situations to judge whether the RFID electronic label 4 loses
It loses；If a RFID electronic label 4 occurs at least one 3 range of reader, which is present in
In RFID electronic label identifying system, not be lose label；Otherwise, if a RFID electronic label 4 is in all readers 3
All do not occur in read range, then RFID electronic label 4 must be loss label.
In order to realize the fast algorithm of detecting for losing label, need accurately to determine a label whether in a reader
Read range in.Programmable logic controller (PLC) collects the ID of all RFID electronic label 4 in all 3 read ranges of reader
Whether data judge a RFID electronic label 4 in the read range of a reader 3.
Process when all RFID electronic label 4 are identified a usually consumption energy consumption is read, therefore, is based on virtual cloth
Shandong nurse filter algorithm rapidly judges a RFID electronic label 4 under the ID data cases for not collecting RFID electronic label 4
Whether in the read range of a reader 3.Virtual Bloom Filter algorithm (Bloom filter) is a time effect
The very high random access structure of rate, it includes one m bit arrays, and using k independent hash functions, they respectively will
Each element in set N is mapped in the range of { 1...m }, when judging whether an element belongs to set N, uses this k
A hash function is verified, when the bit of all hash Function Mappings is entirely 1, it is believed that the element belongs to set N, otherwise
Think that element is not belonging to set N.Certainly this phenomenon that there is false sun, that is to say, that element is actually not belonging to set N, but quilt
Judgement belongs to set N, this is because being possible to set 1 by other elements there are some bit.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
