Embodiment
Below in conjunction with accompanying drawing, structural principle of the present invention and principle of work are described in detail:
Radio RF identification label detection method provided by the invention is mainly: first read the multiple radio RF identification labels in a readable region.Then, judge whether bad radio RF identification label, if had, utilize the mode successively changing this shaded areas size, find out the position of problematic wireless radio frequency identification label.
The inventive method is described in detail below with embodiment.As shown in Figure 2, this figure is radio RF identification label detection method embodiment schematic flow sheet of the present invention.This detection method includes the following step: as shown in Figure 3A, first carry out step 20, the material strip 90 that one is to be detected is provided, this material strip 90 have multiple radio RF identification label to be detected (RFIDTag) 91 and 91a, wherein label 91 represents good wireless radio frequency identification label, and label 91a then represents bad radio RF identification label.Then carry out step 21, read the multiple radio RF identification labels in a readable region.In figure 3 a, the size of this readable region 92, substantially depends on and the scope that reader 93 can read there is no a definite limitation.Then carry out step 22, according to the quantity of the radio RF identification label read in readable region 92, judge whether bad radio RF identification label, if there is no bad label, then judge whether the region not examining side in addition, if also had, carry out step 23, material strip quickly through, and mobile next material strip to be measured is in this readable region.Otherwise, if there is bad label, then, in this readable region, carry out step 24, covers at least two radio RF identification labels with a shaded areas.For Fig. 3 A, total quantity due to the radio RF identification label in readable region is known (18), therefore in step 22, this total quantity (18) can be learnt whether there is bad radio RF identification label in this readable region compared with the total quantity at the radio RF identification label read in this readable region 92.In figure 3 a, owing to having 3 bad labels in readable region 92, what therefore read adds up to 15.According to aforementioned, 18 differ 3 with 15, therefore can judge to have 3 problematic radio RF identification label 91a in current readable region.
As shown in Figure 3 B, after defining bad radio RF identification label, owing to needing the position finding out bad label, the masking material with shielding function is therefore utilized to provide this shaded areas 94 to cover multiple radio RF identification label in this readable region 92 immediately.The size of shaded areas is can cover the area size of plural wireless radio frequency identification label in step 24.After covering, carry out step 25 again and read multiple wireless radio frequency identification labels in this readable region, judge whether the radio RF identification label quantity that can read in this readable region reduces, if do not reduced, then the radio RF identification label represented in shaded areas is all bad label.Then carry out step 26, it is complete whether the label in readable region all detects, if not, carries out step 27 and this shaded areas is moved to next position, then repeats step 25.Otherwise, if there is minimizing, then carries out step 28 and judge to reduce quantity, if the quantity reduced equals the quantity of the radio RF identification label of this crested, the plurality of wireless radio frequency identification label then representing crested is all good label, then return step 26.If the quantity reduced is less than the quantity of the radio RF identification label of this crested, utilizes step 29 successively to change an occlusion detection mode of this shaded areas size, find out the position of problematic wireless radio frequency identification label.
Such as: in figure 3b, this shaded areas size is at the beginning for having the shaded areas 94 can covering three wireless radio frequency identification labels, therefore pass through the sum of the wireless identification identification label read in this readable region after being blinded by three radio RF identification labels after, if find that the sum that can read has lacked three, then the wireless radio frequency identification label represented in this shaded areas 94 is all good label.Otherwise, if find that the sum that can read is less than three with the sum difference that originally can read, then represent, in this shaded areas, there is bad radio RF identification label.Such as: if sum difference is two, represent in three that cover and have two to be good, one is bad label; If sum difference is one, then represent in three that cover and have one to be good, two other is bad label; In addition, if difference is zero, then it is all bad for representing the radio RF identification label covered.And in figure 3b, current the contained region of shaded areas 94 has two good radio RF identification labels 91 and a bad wireless identification identification label 91a, therefore the label number in read readable region 92 can become 13 by 15, therefore can conclude in current shaded areas, to have 1 bad radio RF identification label 91a and two excellent radio RF identification label 91.
How to find out the position of bad label, refer to Fig. 4 A, this figure is occlusion detection mode first embodiment schematic flow sheet of the present invention.When this flow process has bad radio RF identification label mainly for shaded areas, how to search out the embodiment of the position of bad label.The embodiment of Fig. 4 A mainly illustrates the embodiment (such as: three) containing two or more radio RF identification label with shaded areas.First carry out step 290, the scope of this shaded areas is reduced a radio RF identification label and reduce shaded areas to form one.Then carry out step 291, in this shaded areas, reduce with this radio RF identification label that shaded areas covers respective amount.For Fig. 3 B and Fig. 3 C, when finding there is bad radio distinguishing label in shaded areas in step 29, by the scope of this shaded areas by containing the size reduction of three radio RF identification labels to the size containing two radio RF identification labels.And then reduce shaded areas 95 cover corresponding region size radio RF identification label with this in this shaded areas 94.In the embodiment of Fig. 3 C, reduce corresponding to shaded areas 95 to number of labels be two.
As shown in Figure 4 A, then carry out step 292, read the multiple wireless radio frequency identification labels in this readable region, judge the quality of the radio distinguishing label do not hidden in this shaded areas according to the quantity of the radio RF identification label read in readable region.For Fig. 3 C, after covering, recycling reader 93 reads and can read quantity in readable region 92, due under the state of Fig. 3 C, can read the radio RF identification label that can read in region 92 is 14, than utilizing many one of the quantity (13) read during shaded areas 94 at Fig. 3 B.Therefore can learn that uncovered radio RF identification label is good radio RF identification label.Certainly, also can by the reading result of Fig. 3 C compared with the reading result of Fig. 3 A, such as, under shielding status in fig. 3 c, if read comparatively originally do not cover time few two of sum may be read into, then representing the wireless radio frequency identification label covered is good label, and those of ordinary skill in the art can know by inference according to reading result according to the aforesaid spirit of the present invention.Can learn thus, utilize the reading result under shielding status compared with the most original uncovered reading result, the label quality distribution of crested can be learnt.And utilize the reading result of twice different shaded areas size (differing from) to compare, the quality of that label uncovered can be learnt.
Then carry out step 293 and judge to reduce in shaded areas whether have bad label.Due in the embodiment of Fig. 3 C, can learn that compared with reading result when not covering the radio RF identification label reduced in shaded areas 95 at this is a good and bad label according to the reading result of step 292.Now carry out step 294 again, if this reduces in shaded areas still bad radio RF identification label, with step 294 repeat above five steps 290 ~ 294 until the quantity reducing the radio RF identification label that shaded areas can be covered is one.In the embodiment of Fig. 3 C, because this reduces in shaded areas 95, there is bad label, therefore continue this shaded areas to be contracted to only can cover single wireless frequency identification volume label reduce shaded areas 96, as shown in Figure 3 D.Reduce in the position that shaded areas 96 covers at this, carry out step 295, read the multiple radio RF identification labels in this readable region, compared with the number of labels read in unsheltered situation, judge whether the radio RF identification label quantity that can read in this readable region reduces, if reduced, judge that this radio RF identification label of crested is normal radio RF identification label with step 296.If do not reduced, then judge that this radio RF identification label of crested is bad radio RF identification label with step 297.
For the situation of Fig. 3 D, the total number of labels read under the shielding status of Fig. 3 D can than the total number of labels read under the situation of Fig. 3 A also few, and the label that therefore can predicate crested is good label.And another does not cover the label can learnt as bad.The judgment mode of step 294 also can by the sum read when covering with front once (cover two) time the sum that reads compared with, to judge the quality of uncovered label.Such as illustrate for Fig. 3 C and Fig. 3 D, the number of tags read under the state of Fig. 3 C is 14, and the number of tags read under the condition of Fig. 3 D is 14, therefore can conclude non-crested to label be bad radio RF identification label.Subsequently, return shown in Fig. 2, after picking out bad radio RF identification labels all in this shaded areas, return step 25, this shaded areas is moved to next position, then repeats step 25 to 29 until detect at all bad wireless identification identification labels of this readable region.And then get back to step 23, the label of next readable region is detected.
As shown in Figure 4 B, this figure is occlusion detection mode second embodiment schematic flow sheet of the present invention.The flow process of the present embodiment is illustrating when containing two radio RF identification labels for shaded areas.First carry out step 290a, reduce shaded areas with one in this shaded areas, cover a radio RF identification label.Then carry out step 291a and read multiple wireless radio frequency identification labels in this readable region, judge whether the radio RF identification label quantity that can read in this readable region reduces, if reduced, judge that this radio RF identification label of crested is normal radio RF identification label with step 292a.If do not reduced, then judge that this radio RF identification label of crested is bad radio RF identification label with step 293a.The shaded areas of different size can be spreaded to by the spirit of Fig. 4 A to Fig. 4 B, such as: if shaded areas is the region containing four wireless radio frequency identification labels, also be first utilize to cover four labels and read readable quantity in readable region again, if the readable quantity of readable region has lacked four, then representing labels all in shaded areas has been good label.Otherwise, if the few quantity of the readable quantity of readable region is less than four, then represents in four labels in shaded areas and have bad label.Therefore the size reducing shaded areas progressively, when shaded areas dwindles into three, then the quantity read according to readable region judges that uncovered label is defective products or non-defective unit.Then, then continue to dwindle into two, judge that uncovered label is non-defective unit or defective products.
