Step S304, controls RFID read-write unit and carries out data interaction with RFID medium, and judge the data interaction of the two
The most successful
The concrete step that performs is with step S203.
Step S305, when judging the data interaction success of RFID read-write unit and RFID medium, calculates RFID read-write list
RFID medium is written and read operate the required time in unit and RFID medium can call duration time
When judging the data interaction success of RFID read-write unit and RFID medium, control unit calculates RFID read-write unit
RFID medium is written and read operates the required time and RFID medium can call duration time.Wherein, RFID read-write unit is to RFID
Medium is written and read operating the required time, refers to send RFID medium to be written to by RFID read-write unit to RFID medium
Rf data and/or from RFID medium read written into rf data required for time, control unit according to RFID read
RFID medium is written and read during operation writing by communication speed and RFID read-write unit between r/w cell and RFID medium
And/or RFID medium is written and read operating the required time by the length computation RFID read-write unit of the rf data read, than
As, the communication speed between RFID read-write unit and RFID medium is f bps, and RFID medium is carried out by RFID read-write unit
The a length of s byte of the rf data writing and/or reading during read-write operation, then RFID medium is carried out by RFID read-write unit
Time needed for read-write operation be t1(unit be the second) be:
T1=(8*s/f) (formula one)
RFID medium can call duration time, refer to carry during RFID medium, RFID read-write unit 17 and RFID medium
Can successfully carry out the time of data interaction, i.e. when RFID read-write unit is with the data interaction success of RFID medium, data interaction
Time.Such as, during conveying RFID medium, control unit controls RFID read-write unit and carries out data with RFID medium
Alternately, RFID medium sequentially passes through position a1 and position a2, and when reaching position a1, RFID read-write unit is with RFID medium first
Data interaction success, between position a1 to position a2, RFID read-write unit and the data interaction of RFID medium all can be successful,
After the a2 of position, the data interaction failure of RFID read-write unit and RFID medium, then RFID medium by position a1 to position
The time of a2 is that RFID medium can call duration time.Fig. 8 a to Fig. 8 c is that RFID medium is when moving in the transfer passage of printing equipment
The schematic diagram of its change in location, as shown in Figure 8 a, when printing beginning, along medium conveying direction, the forward position of RFID medium P is positioned to be beaten

The displacement of RFID medium P of record be L3(unit be millimeter), i.e. distance between top of form 43 and position 44 is
L3, from Fig. 8 b, when RFID read-write unit and RFID medium P data interaction success first, the forward position institute of RFID medium P is in place
Putting 44 with the distance L4(unit of the second centrage 42 of RFID antenna 171 is millimeter) be:
L4=(L2-L3) (formula two)
Wherein, L2(unit is millimeter) it is between top of form 43 and the second centrage 42 of RFID antenna 171
Distance.
Due to the RFID antenna 171 of RFID read-write unit relative to it along being perpendicular to the second centrage of medium conveying direction
42 is symmetrical, and therefore, RFID antenna 171 is symmetrical relative to the second centrage 42 along electromagnetic field produced by medium conveying direction.Root
Understanding according to this principle, as shown in Figure 8 c, RFID medium P moves in transfer passage, along medium conveying direction, RFID medium P's
When distance L5 between tailing edge position 45 and the second centrage 42 of RFID antenna 171 and L4 approximately equal, RFID read-write
The data interaction of unit and RFID medium P will be failed, therefore, RFID medium P through the working region of RFID read-write unit,
Can be in successful data mutual time at RFID read-write unit and RFID medium P, the displacement L6(unit of RFID medium P is
Millimeter) be:
L6=L+L4+L5
Due to
L5≈L4
Therefore
L6 ≈ L+2*L4 (formula three)
Wherein, L(unit is millimeter) it is the RFID medium P length along medium conveying direction, if the printing speed of printing equipment
Degree for v mm/second, then RFID medium can call duration time t2(unit be the second) be:
T2=L6/v (formula four)
Formula two, formula three are substituted into formula four, obtain:
T2 ≈ (L+2*L2-2*L3)/v (formula five)
Step S306, it is judged that RFID medium is written and read whether operating the required time more than RFID by RFID read-write unit
Medium can call duration time
Control unit judges that RFID medium is written and read operating whether required time t1 is more than by RFID read-write unit
RFID medium can call duration time t2, if it is, perform step S307, otherwise, perform step S308.
Step S307, is written and read operating required time adjustment print speed to RFID medium according to RFID read-write unit
When RFID read-write unit be written and read RFID medium operating required time t1 can communicate more than RFID medium time
Between t2 time, show when RFID medium moves in transfer passage, can hand over by successful data at RFID read-write unit and RFID medium
In mutual time t2, RFID read-write unit can not complete the operation being written and read RFID medium, therefore, in order to avoid for obtaining
Time enough is so that RFID read-write unit can complete the operation being written and read RFID medium, and interrupts the conveying of RFID medium
And/or print, control unit calculates the RFID read-write unit of gained according to step S305 and is written and read RFID medium operating institute
The time t1 needed adjusts print speed, makes the RFID medium after adjustment print speed can be more than RFID read-write unit pair by call duration time
RFID medium is written and read operating the required time, it is ensured that can be in call duration time at RFID medium, and RFID read-write unit can be complete
The operation that RFID medium is written and read in pairs.From formula four, v=L6/t2, when arrange RFID medium can call duration time with
RFID read-write unit be written and read RFID medium operating required time t1 equal time, need print speed v ' (unit is
Mm/second) it is adjusted to:
V '=L6/t1 (formula six)
Formula one, formula two, formula three, formula four are substituted into formula six, obtain:
V ' < [f*(L+2*L2-2*L3)]/(8*s)
Therefore, if it is desired that RFID medium can be written and read operation more than RFID read-write unit by call duration time to RFID medium
The required time, need print speed v after making adjustment ' meet v ' < [f*(L+2*L2-2*L3)]/(8*s).

Write the phenomenon of failure, it is preferable that control unit carries out reserving enough surpluses when print speed adjusts, and makes RFID medium to communicate
RFID medium is written and read operating the required time, so that RFID read-write unit is to RFID by the time much larger than RFID read-write unit
Rf data read-write can be re-started during the operation failure that medium is written and read, such as, by adjusting print speed, make RFID
Medium can be written and read operating 3 times of required time t1 more than RFID read-write unit by call duration time to RFID medium, i.e. arranges
V ' < L6/ (3*t1), so that RFID medium can be in call duration time, the operation that RFID medium is written and read by RFID read-write unit
Can carry out twice retrying during failure.
Step S308, controls RFID read-write unit and RFID medium is written and read operation, and with the print speed after adjusting
