Abstract

A management PC comprises a polling combination table 11a for storing data (combination data) where a combination of reader/writers, which are not problematic when being polled simultaneously, and a polled flag. The management PC examines combination data of each row by sequentially referencing the polling combination table starting at the first row in the polling process of a reader/writer. Then, one or a plurality of reader/writers set in the combination data are concurrently polled. Then, the polled flags of the polled reader/writers are set to “1”. After referencing the last row of the polling combination table, the management PC clears the polled flags of all of rows of the polling combination table to “0”, and repeats the above described series of operations.

Claims

1. An article managing system having a wireless tag attached to an article, a reader/writer for reading a unique ID of the wireless tag with a wireless communication via an antenna, and managing means for instructing the reader/writer to obtain the unique ID of the wireless tag, comprising:

deciding means for deciding a reader/writer to which a UID obtainment command is transmitted; and

controlling means for transmitting the UID obtainment command to the reader writer decided by said deciding means.

2. The article managing system according to claim 1, wherein

said deciding means comprises

a combination table for storing combination data of reader/writers to which the UID obtainment command can be simultaneously transmitted, and

first selecting means for deciding one or a plurality of reader/writers set in the combination data as reader/writers, to which the UID obtainment command is transmitted, by referencing the combination data within the combination table.

3. The article managing system according to claim 1, wherein:

the article is stored in a shelf having a door; and

said deciding means comprises

monitoring means for monitoring an opening/closing state of the door of the shelf, and

second selecting means for deciding a reader/writer obtaining a unique ID of a wireless tag of an article stored in the shelf, the door of which is open, as a reader/writer, to which the UID obtainment command is transmitted, based on a result of detection of said monitoring means.

4. The article managing system according to claim 3, wherein

said monitoring means comprises

a sensor for detecting opening/closing of the door provided in the shelf, and

detecting means for detecting that the door of the shelf is open, based on a result of detection of said sensor.

5. The article managing system according to claim 4, wherein

said sensor is placed in the shelf.

6. The article managing system according to claim 5, wherein

said detecting means is provided within the managing means, and said sensor and said detecting means are connected with a communication line.

7. The article managing system according to claim 1, wherein:

the article is stored in a shelf having a door; and

said deciding means comprises

detecting means for detecting an opening/closing angle of the door of the shelf, and

third selecting means for deciding a reader/writer obtaining a unique ID of a wireless tag of an article stored in a shelf having a door, which is open at a specified angle or more, as a reader/writer, to which the UID obtainment command is transmitted, based on a result of detection of said detecting means.

8. The article managing system according to claim 7, wherein

said third selecting means comprises

an angle setting table for storing the instructed angle, and

determining means for determining that the door is open at the specified angle or more by making a comparison between the specified angle stored in said angle setting table and the opening/closing angle of the door, which is input from said detecting means.

9. The article managing system according to claim 7, wherein

said detecting means is placed between the shelf and the door.

10. The article managing system according to claim 9, wherein

said detecting means is provided within the managing means, and said detecting means and said third selecting means are connected with a communication line.
