Definitions

  • the present invention relates to a bulk reader of RFID tags.
  • RFID tags it is possible to read or write a number of RFID tags within an accessible range successively in bulk. At that time, only the tags that could be recognized by the reader/writer are accessed, and thus, the presence or absence of the tags that could not be recognized cannot be determined.
  • tags that are unrecognizable due to the orientation and position of the tag or due to a defect in the tag. Determination of the presence or absence of such unrecognizable tags is essential to improving the accuracy of bulk access.
  • the tag reader is a tag reader for detecting the number of goods via a tag attached to the goods and counting the number of tags read by a reader/writer, and has determination means for determining whether reading of the tag has been properly conducted or not by comparing the quantity of goods mounted on a goods mounting means to which a tag having quantity information relating to the quantity of mounted goods is attached and the quantity information of the tag attached to the goods mounting means.
  • FIG. 1 is a block diagram of an RFID system according to the embodiments of the present invention.
  • FIG. 2 is a diagram explaining a first embodiment of the present invention
  • FIG. 3 is a flowchart of the bulk access processing that a reader/writer of the first embodiment of the present invention performs
  • FIG. 4 is a diagram explaining the second embodiment of the present invention.
  • FIG. 5 is a flowchart of the bulk access processing that the reader/writer in the second embodiment performs
  • FIG. 6 is a diagram explaining the third embodiment of the present invention.
  • FIG. 7 is a flowchart of the bulk access processing that the reader/writer of the third embodiment performs.
  • FIG. 1 is a block diagram of an RFID system according to the embodiments of the present invention.
  • An RFID control unit 12 is connected to an upper-level system 10 such as an application for managing overall workflow in a place of business.
  • the RFID control unit 12 executes a series of processes in accordance with the embodiments of the present invention.
  • a display device or an audio device 11 is connected to the RFID control unit 12 , and when the RFID control unit 12 detects an error, an operator is notified of the error occurrence.
  • a reader/writer 13 is connected to the RFID control unit 12 , radio waves are transmitted to a tag 16 via an antenna 14 , and the information of the tag 16 is read.
  • the tag 16 is attached to each piece of the goods etc. mounted on a palette 15 .
  • the goods mounted on the palette 15 are counted as a single unit and they move down the operation process.
  • the reader/writer 13 reads the information of the tag attached to the goods on the palette 15 .
  • the tag information is read, the information of the tag attached to all the goods on the palette 15 and the information of the tag attached to the palette 15 are read successively.
  • Such a manner of accessing a number of tags in units of palettes etc. successively as just described above is referred to as bulk access.
  • FIG. 2 is a diagram explaining a first embodiment of the present invention.
  • a tag is placed on a carrier (or a palette or the like) used in a bulk access operation of the tags attached to goods.
  • the quantity of the tags attached to the goods on the carrier is recognized by accessing the tag on the carrier and reading the written information (indicating the number of goods that should be mounted on the carrier or the palette or the like).
  • the normality of the bulk access can be evaluated (in other words, the presence or absence of an unrecognized tag is determined).
  • a tag is placed on the palette.
  • the quantity of the mounted goods is written on the tag on the palette (other information such as a carrier ID is also stored).
  • the quantity information written on the tag attached to the carrier is read.
  • the accessed quantity of tags attached to goods is counted. The above two kinds of information are compared. In the comparison processing, the decision is made as below.
  • FIG. 3 is a flowchart of the bulk access processing performed by a reader/writer of the first embodiment of the present invention.
  • step S 10 first, quantity information is read from the tag on the palette, and the quantity information of the tag on the palette is stored.
  • step S 11 the number of tags attached to the goods is counted, and the count information is stored as an accessed number of tags attached to the goods.
  • the processing in steps S 10 and S 11 is performed in bulk access in units of palettes.
  • step S 12 the quantity information of the tags on the palette is compared with the accessed number of tags attached to the goods, and whether the two are equal or not is determined. If the determination in step S 12 is Yes, the processing is recognized as normal and is terminated. If the determination in step S 12 is No, then whether the accessed number is within the predetermined number or not is determined in step S 13 .
  • step S 12 When the processing is determined to be abnormal in the determination of step S 12 , a notification to instruct the operator to cause the palette to pass in front of the antenna is issued, and the number of times that the palette passes in front of the antenna is referred to as the number of times accessed.
  • the processing in step S 13 determines whether the number of times that the palette passes in front of the antenna is within the predetermined number of times or not. If the determination in step S 13 is Yes, an instruction is issued to have the operator restore the palette and cause the palette to pass in front of the antenna again, and the processing returns to step S 10 . If the determination in step S 13 is No, it is determined to be abnormal, and in step S 14 , the operator is notified of the error and the processing is terminated.
  • FIG. 4 is a diagram explaining the second embodiment of the present invention.
  • tags are placed in (plural) positions on the carrier where goods are to be mounted.
  • quantity information is stored in each of the tags in ascending order, starting from zero and incremented upward by one in each tag; the number placed at the first position in which goods are not mounted is the number of goods stored.
  • the tags on the carrier are blocked in sequence (blocked by the goods themselves or by providing to the carrier a mechanism to block the tags at the mounting).
  • the mounting of the goods on the carrier is performed in the order from the tag with the smallest quantity information.
  • the quantity information written on the tag on the carrier is read, and the smallest piece of the quantity information is set as a reference.
  • the quantity of accessed tags attached to the goods is counted. The above two kinds of information are compared with each other. As a result of the reference, the determination is made as below.
  • the determination is made that the situation is normal. If the accessed number of tags attached to the goods is 2 or less, it is determined that there are tags that could not be detected. If the accessed number of tags attached to the goods is 4 or above, the determination is made that the situation is abnormal (possibility of reading tags other than those on the carrier).
  • FIG. 5 is a flowchart of the bulk access processing that the reader/writer in the second embodiment performs.
  • step S 20 the quantity information is read from plural tags on the carrier, and the smallest value of the plural quantity information is stored as reference quantity information.

When the determination in step S 22 is Yes, the processing is terminated. When the determination in step S 22 is No, whether the number of times accessed is within the predetermined number of times or not is determined in step S 23 . When the determination in step S 23 is Yes, the processing goes back to step S 20 , and when the determination in step S 23 is No, the error processing is performed in step S 24 , and the processing is terminated.
