Abstract

Antennas X and Y are disposed such that they are opposed and sandwich a product case to which an IC tag is attached. A transmitting part (120) radiates an IC tag reading radio wave from the antenna X. An antenna-X receiving part (130a) derives the data of an IC tag from a response radio wave received by the antenna X, and then stores it into a read data storage part (140). An antenna-Y receiving part (130b) derives the data of the IC tag from a response radio wave received by the antenna Y, and then stores it into the read data storage part (140).

[0006] 例えば、図 10は、図 9に示した製品ケースが四つ積み付けられた場合の ICタグの 読取を示す図である。この場合、 ICタグ読取装置は、 ICタグ Dについては、アンテナ との間に障害物がないため容易に読み取ることができる。また、 ICタグ Bおよび ICタ グ Cについても、これらの ICタグが通信範囲にあり、 PET容器および食用油は電波を 通すため、読み取ることができる。しかし、 ICタグ Aについては、金属缶がアンテナか らの ICタグ読取用電波および ICタグ A力もの応答電波を遮蔽する障害物として作用 するため、読み取ることができない。 [0006] For example, FIG. 10 is a diagram showing reading of an IC tag when four product cases shown in FIG. 9 are stacked. In this case, the IC tag reader can easily read the IC tag D because there is no obstacle between the IC tag D and the antenna.

However, for IC tag A, the metal can acts as an obstacle to shield the radio waves for reading the IC tag from the antenna and the response radio waves from the power of the IC tag A. Therefore, it cannot be read.

[0035] 以下に、本発明に係る ICタグ読取装置、 ICタグ読取方法および ICタグ読取プログ ラムの実施例を図面に基づいて詳細に説明する。なお、ここでは、本発明を図 8に示 した入庫管理システムに適用した場合にっ 、て二つの実施例を中心に説明するが、 これらの実施例により本発明が限定されるものではない。 実施例 1  Hereinafter, embodiments of an IC tag reading device, an IC tag reading method, and an IC tag reading program according to the present invention will be described in detail with reference to the drawings. Here, two examples will be mainly described when the present invention is applied to the warehousing management system shown in FIG. 8, but the present invention is not limited to these examples. Example 1
[0036] まず、本実施例 1に係る ICタグ読取システムの概念について説明する。図 1は、本 実施例 1に係る ICタグ読取システムの概念を説明するための説明図である。同図に 示すように、この ICタグ読取システムでは、パレット上に積み付けられた製品ケースを 挟んで相対する位置に二つのアンテナを配置する。  First, the concept of the IC tag reading system according to the first embodiment will be described. FIG. 1 is an explanatory diagram for explaining the concept of the IC tag reading system according to the first embodiment. As shown in the figure, in this IC tag reading system, two antennas are placed at opposite positions across the product case stacked on the pallet.
[0037] そして、 ICタグを読み取る場合には、アンテナ Xが読取用の電波を発射し、アンテ ナ Xおよびアンテナ Yで ICタグの応答電波を受信する。したがって、アンテナ Xだけ では応答電波を受信することができな力つた ICタグ Aについても、アンテナ Yによつ て応答電波を受信することができる。 [0038] このように、本実施例 1に係る ICタグ読取システムでは、製品ケースを挟んで相対 する位置に二つのアンテナを配置することによって、障害物の影響を受けることなく 全ての ICタグを読み取ることができる。 [0037] When reading the IC tag, the antenna X emits a radio wave for reading, and the antenna X and the antenna Y receive the response radio wave of the IC tag. Therefore, even for the strong IC tag A that cannot receive the response radio wave with the antenna X alone, the response radio wave can be received with the antenna Y. [0038] As described above, in the IC tag reading system according to the first embodiment, by arranging two antennas at positions facing each other across the product case, all the IC tags can be removed without being affected by an obstacle. Can be read.
[0039] 次に、本実施例 1に係る ICタグ読取システムの構成について説明する。図 2は、本 実施例 1に係る ICタグ読取システムの構成を示す機能ブロック図である。同図に示す ように、この ICタグ読取システムは、 ICタグ読取装置として動作するコントローラ 100と 照合装置 200とが接続されて構成される。  Next, the configuration of the IC tag reading system according to the first embodiment will be described. FIG. 2 is a functional block diagram of the configuration of the IC tag reading system according to the first embodiment. As shown in the figure, this IC tag reading system is configured by connecting a controller 100 operating as an IC tag reading device and a verification device 200.
[0040] コントローラ 100は、 ICタグに記憶されたデータを読み取って照合装置 200に送信 する装置であり、読取指示部 110と、発信部 120と、アンテナ X受信部 130aと、アン テナ Y受信部 130bと、読取データ記憶部 140と、読取データ送信部 150と、通信部 160とを有する。  [0040] The controller 100 is a device that reads the data stored in the IC tag and transmits the data to the verification device 200. The reading instruction unit 110, the transmission unit 120, the antenna X reception unit 130a, and the antenna Y reception unit 130b, a read data storage unit 140, a read data transmission unit 150, and a communication unit 160.
[0041] 読取指示部 110は、製品ケースが積まれたパレットの接近を検出して発信部 120に 対して ICタグ読取用電波の発射を指示する処理部である。また、この読取指示部 11 0は、照合装置 200から ICタグ読取指示を受けた場合にも、発信部 120に対して IC タグ読取用電波の発射を指示する。  The reading instruction unit 110 is a processing unit that detects the approach of a pallet loaded with product cases and instructs the transmission unit 120 to emit radio waves for reading an IC tag. The reading instruction unit 110 also instructs the transmitting unit 120 to emit an IC tag reading radio wave when receiving an IC tag reading instruction from the verification device 200.
[0042] 発信部 120は、読取指示部 110の指示に従って、 ICタグ読取用電波を発射する処 理部である。具体的には、この発信指示部 120は、アンテナ Xを使って ICタグ読取用 電波を発射する。  Transmitting unit 120 is a processing unit that emits an IC tag reading radio wave in accordance with an instruction from reading instruction unit 110. Specifically, the transmission instructing unit 120 uses the antenna X to emit an IC tag reading radio wave.
[0043] アンテナ X受信部 130aは、アンテナ Xが受信した応答電波力も ICタグのデータを 取り出して読取データ記憶部 140に格納する処理部である。ただし、このアンテナ X 受信部 130aは、応答電波から取り出したデータが既にアンテナ Y受信部 130bによ つて読取データ記憶部 140に格納されている場合には、そのデータの格納を行わな い。  [0043] The antenna X receiving unit 130a is a processing unit that extracts the data of the IC tag and stores the response radio wave power received by the antenna X in the read data storage unit 140. However, when the data extracted from the response radio wave is already stored in the read data storage unit 140 by the antenna Y reception unit 130b, the antenna X reception unit 130a does not store the data.
[0044] アンテナ Y受信部 130bは、アンテナ Yが受信した応答電波から ICタグのデータを 取り出して読取データ記憶部 140に格納する処理部である。ただし、このアンテナ Y 受信部 130aも、 ICタグ力も読み取ったデータが既にアンテナ X受信部 130aによつ て読取データ記憶部 140に格納されている場合には、データの格納を行わない。  [0044] The antenna Y receiving unit 130b is a processing unit that extracts data of the IC tag from the response radio wave received by the antenna Y and stores it in the read data storage unit 140. However, the antenna Y receiving unit 130a also does not store data when the data read by the IC tag force is already stored in the read data storage unit 140 by the antenna X receiving unit 130a.
[0045] このように、アンテナ X受信部 130aおよびアンテナ Y受信部 130bが、別のアンテナ が受信した応答電波力も ICタグのデータを取り出すことによって、片方のアンテナだ けが応答電波を受信可能な場合にも、 ICタグのデータを読み取ることができる。 [0045] In this manner, antenna X receiving unit 130a and antenna Y receiving unit 130b are different antennas.

[0054] 次に、本実施例 1に係るコントローラ 100による ICタグ読取処理の処理手順につい て説明する。図 4は、本実施例 1に係るコントローラ 100による ICタグ読取処理の処理 手順を示すフローチャートである。  Next, a processing procedure of IC tag reading processing by the controller 100 according to the first embodiment will be described. FIG. 4 is a flowchart of the process procedure of the IC tag reading process performed by the controller 100 according to the first embodiment.
[0055] 同図に示すように、この ICタグ読取処理では、読取指示部 110が製品ケースが積 まれたパレットの接近を検出して発信部 120に ICタグ読取を指示し (ステップ S101) 、発信部 120が ICタグ読取用電波をアンテナ Xから発射する (ステップ S102)。  As shown in the figure, in this IC tag reading process, the reading instructing unit 110 detects the approach of the pallet on which the product case is loaded and instructs the transmitting unit 120 to read the IC tag (step S101). Transmitter 120 emits an IC tag reading radio wave from antenna X (step S102).
[0056] そして、アンテナ X受信部 130aがアンテナ Xが受信した応答電波力も ICタグのデ ータを取り出して読取データ記憶部 140に格納し、アンテナ Y受信部 130bがアンテ ナ Yが受信した応答電波力も ICタグのデータを取り出して読取データ記憶部 140に 格納する (ステップ S103)。ただし、アンテナ X受信部 130aおよびアンテナ Y受信部 130bは、応答電波から取り出したデータが既に読取データ記憶部 140に格納され ている場合には、そのデータの格納は行わない。  [0056] Then, the response radio wave force received by the antenna X by the antenna X receiving unit 130a also retrieves the IC tag data and stores it in the read data storage unit 140, and the antenna Y receiving unit 130b receives the response received by the antenna Y. The radio wave power is also extracted from the IC tag and stored in the read data storage unit 140 (step S103). However, when the data extracted from the response radio wave is already stored in the read data storage unit 140, the antenna X reception unit 130a and the antenna Y reception unit 130b do not store the data.
[0057] そして、読取指示部 110による読取指示から所定の時間経過後に読取データ送信 部 150が ICタグ力も読み取られたデータを読取データ記憶部 140から取り出して照 合装置 200に送信する (ステップ S104)。  [0057] Then, after a predetermined time has elapsed from the reading instruction by the reading instructing unit 110, the read data transmitting unit 150 takes out the read data of the IC tag force from the read data storage unit 140 and transmits it to the collating device 200 (step S104). ).
[0058] このように、アンテナ X受信部 130aがアンテナ Xが受信した応答電波から ICタグの データを取り出して読取データ記憶部 140に格納し、アンテナ Y受信部 130bがアン テナ Yが受信した応答電波力も ICタグのデータを取り出して読取データ記憶部 140 に格納することによって、片方のアンテナが応答電波を受信できない場合にも、 ICタ グのデータを読み取ることができる。  [0058] Thus, the antenna X receiving unit 130a extracts the IC tag data from the response radio wave received by the antenna X and stores it in the read data storage unit 140, and the antenna Y receiving unit 130b receives the response received by the antenna Y. As for the radio wave power, the IC tag data can be read even if one of the antennas cannot receive the response radio wave by retrieving the IC tag data and storing it in the read data storage unit 140.
[0059] 上述してきたように、本実施例 1では、発信部 120がアンテナ Xから ICタグ読取用電 波を発射し、 ICタグ力もの応答電波を ICタグを挟んで相対する位置に配置したアン テナ Xおよびアンテナ Yで受信することとしたので、製品ケースに収められた金属缶 が片方のアンテナに対して障害物として作用する場合にも、他のアンテナで応答電 波を受信することができ、 ICタグの読取性能を改善することができる。  [0059] As described above, in the first embodiment, the transmitter 120 emits an IC tag reading radio wave from the antenna X, and the response radio wave having the power of the IC tag is arranged at a position facing the IC tag. Since antenna X and antenna Y are used for reception, even if a metal can contained in the product case acts as an obstacle to one antenna, the other antenna can receive the response wave. And the reading performance of the IC tag can be improved.
[0060] なお、本実施例 1では、パレットを挟んで相対する位置に二つのアンテナを配置し て応答電波を受信する場合について説明したが、本発明はこれに限定されるもので はなく、三つ以上のアンテナをパレットを囲むように配置して応答電波を受信する場 合にも同様に適用することができる。 [0060] In the first embodiment, two antennas are arranged at opposite positions across the pallet. However, the present invention is not limited to this, and the same applies to the case where three or more antennas are arranged around the pallet to receive the response radio wave. Can be applied.

[0061] ところで、上記実施例 1では、金属缶が ICタグ力もの応答電波に対して障害物とし て作用する場合について説明した。し力しながら、 ICタグからの応答電波だけでなく 、発信部 120から発射される ICタグ読取用電波に対しても金属缶が障害物として作 用する場合もある。そこで、本実施例 2では、 ICタグ読取用電波を二つのアンテナか ら順に発射することによって、電波障害物がある場合にも ICタグ読取用電波を ICタグ へ到達させることができる ICタグ読取システムについて説明する。  By the way, in the first embodiment, the case where the metal can acts as an obstacle to the response radio wave having the power of the IC tag has been described. However, the metal can may act as an obstacle not only for the response radio wave from the IC tag but also for the radio wave for reading the IC tag emitted from the transmitter 120. Therefore, in this second embodiment, the IC tag reading radio wave can reach the IC tag even when there is a radio wave obstruction by emitting the IC tag reading radio wave sequentially from the two antennas. The system will be described.
[0062] まず、本実施例 2に係る ICタグ読取システムの構成について説明する。図 5は、本 実施例 2に係る ICタグ読取システムの構成を示す機能ブロック図である。同図に示す ように、この ICタグ読取システムは、コントローラ 300と照合装置 200とが接続されて 構成される。なお、ここでは説明の便宜上、図 2に示した各部と同様の役割を果たす 機能部については同一符号を付すこととしてその詳細な説明を省略する。  First, the configuration of the IC tag reading system according to the second embodiment will be described. FIG. 5 is a functional block diagram of the configuration of the IC tag reading system according to the second embodiment. As shown in the figure, this IC tag reading system is configured by connecting a controller 300 and a verification device 200.

[0065] 読取指示部 310は、製品ケースが積まれたパレットの接近を検出してまずアンテナ X発信部 320aに対して ICタグ読取用電波の発射を指示し、所定時間経過後アンテ ナ Y発信部 320bに対して ICタグ読取用電波の発射を指示する処理部である。  [0065] Reading instruction unit 310 detects the approach of the pallet loaded with the product case, and first instructs antenna X transmitting unit 320a to emit radio waves for reading the IC tag. After a predetermined time has elapsed, antenna Y is transmitted. The processing unit instructs the unit 320b to emit an IC tag reading radio wave.
[0066] この読取指示部 310が、アンテナ X発信部 320aおよびアンテナ Y発信部 320bに 対して順に ICタグ読取用電波の発射を指示することによって、電波障害物によって 片方のアンテナからは ICタグ読取用電波を到達させることができない ICタグに対して も他のアンテナ力 ICタグ読取用電波を到達させることができる。 [0067] そして、アンテナ X受信部 130aは、アンテナ Xから発射した ICタグ読取用電波に対 してアンテナ Xが受信した応答電波力 データを取り出して読取データ記憶部 140に 格納し、次に、アンテナ Yから発射した ICタグ読取用電波に対してアンテナ Xが受信 した応答電波力もデータを取り出して読取データ記憶部 140に格納する。 [0066] The reading instruction unit 310 sequentially instructs the antenna X transmission unit 320a and the antenna Y transmission unit 320b to emit radio waves for reading the IC tag. Other antenna forces can be made to reach IC tag reading radio waves even for IC tags that cannot receive radio waves. [0067] Then, the antenna X receiving unit 130a extracts the response radio wave power data received by the antenna X in response to the IC tag reading radio wave emitted from the antenna X, stores it in the read data storage unit 140, and then The response radio wave power received by the antenna X with respect to the IC tag reading radio wave emitted from the antenna Y is also extracted and stored in the read data storage unit 140.

[0069] なお、アンテナ X受信部 130aおよびアンテナ Y受信部 130bは、応答電波から取り 出したデータが既に読取データ記憶部 140に格納されている場合には、そのデータ を読取データ記憶部 140に格納しな 、。  [0069] When the data extracted from the response radio wave is already stored in the read data storage unit 140, the antenna X reception unit 130a and the antenna Y reception unit 130b store the data in the read data storage unit 140. Don't store it.
[0070] 次に、本実施例 2に係るコントローラ 300による ICタグ読取処理の処理手順につい て説明する。図 6は、本実施例 2に係るコントローラ 300による ICタグ読取処理の処理 手順を示すフローチャートである。  Next, a processing procedure of IC tag reading processing by the controller 300 according to the second embodiment will be described. FIG. 6 is a flowchart of the process procedure of the IC tag reading process performed by the controller 300 according to the second embodiment.
[0071] 同図に示すように、この ICタグ読取処理では、読取指示部 110が製品ケースが積 まれたパレットの接近を検出してアンテナ X発信部 320aに対してアンテナ Xからの IC タグ読取用電波の発射を指示する (ステップ S201)。  As shown in the figure, in this IC tag reading process, the reading instruction unit 110 detects the approach of the pallet on which the product case is loaded, and reads the IC tag from the antenna X to the antenna X transmitting unit 320a. Instructs emission of radio waves (step S201).
[0072] すると、アンテナ X発信部 320aが ICタグ読取用電波をアンテナ Xから発射し (ステ ップ S 202)、アンテナ X受信部 130aがアンテナ Xが受信した応答電波から ICタグの データを取り出して読取データ記憶部 140に格納し、アンテナ Y受信部 130bがアン テナ Yが受信した応答電波力も ICタグのデータを取り出して読取データ記憶部 140 に格納する（ステップ S203)。  [0072] Then, the antenna X transmitter 320a emits an IC tag reading radio wave from the antenna X (step S202), and the antenna X receiver 130a extracts the IC tag data from the response radio wave received by the antenna X. Then, the response radio wave force received by the antenna Y by the antenna Y receiving unit 130b is also extracted from the IC tag and stored in the read data storing unit 140 (step S203).
[0073] ただし、アンテナ X受信部 130aおよびアンテナ Y受信部 130bは、応答電波から取 り出したデータが既に読取データ記憶部 140に格納されている場合には、そのデー タの格納は行わない。  [0073] However, antenna X receiving unit 130a and antenna Y receiving unit 130b do not store the data when the data extracted from the response radio wave is already stored in read data storage unit 140. .
[0074] そして、読取指示部 110が所定の時間経過後にアンテナ Y発信部 320bに対して アンテナ Yからの ICタグ読取用電波の発射を指示する (ステップ S 204)。すると、ァ ンテナ Y発信部 320bが ICタグ読取用電波をアンテナ Yから発射し (ステップ S205) 、アンテナ X受信部 130aがアンテナ Xが受信した応答電波から ICタグのデータを取 り出して読取データ記憶部 140に格納し、アンテナ Y受信部 130bがアンテナ Yが受 信した応答電波力 ICタグのデータを取り出して読取データ記憶部 140に格納する (ステップ S 206)。 [0074] Then, after a predetermined time has elapsed, reading instruction unit 110 instructs antenna Y transmitting unit 320b to emit an IC tag reading radio wave from antenna Y (step S204). Then, antenna Y transmitter 320b emits an IC tag reading radio wave from antenna Y (step S205). The antenna X receiving unit 130a extracts the IC tag data from the response radio wave received by the antenna X and stores it in the read data storage unit 140, and the antenna Y reception unit 130b receives the response radio wave force received by the antenna Y. IC tag Is extracted and stored in the read data storage unit 140 (step S206).
[0075] ただし、アンテナ X受信部 130aおよびアンテナ Y受信部 130bは、応答電波から取 り出したデータが既に読取データ記憶部 140に格納されている場合には、そのデー タの格納は行わない。  [0075] However, antenna X receiving unit 130a and antenna Y receiving unit 130b do not store the data when the data extracted from the response radio wave is already stored in read data storage unit 140. .
[0076] そして、読取指示部 110による読取指示から一定の時間経過後に読取データ送信 部 150が ICタグ力も読み取られたデータを読取データ記憶部 140から取り出して照 合装置 200に送信する (ステップ S207)。  [0076] Then, after a lapse of a certain time from the reading instruction by the reading instruction unit 110, the read data transmission unit 150 takes out the read data of the IC tag force from the reading data storage unit 140 and transmits it to the collation device 200 (step S207). ).
[0077] このように、アンテナ X発信部 320aおよびアンテナ Y発信部 320bが順に ICタグ読 取用電波を発射することによって、片方のアンテナ力も ICタグ読取用電波を到達させ ることができな 、ICタグに対しても、他のアンテナ力 ICタグ読取用電波を到達させ ることがでさる。  [0077] As described above, the antenna X transmitting unit 320a and the antenna Y transmitting unit 320b sequentially emit the IC tag reading radio wave, so that the antenna force of one side cannot reach the IC tag reading radio wave. Another antenna force can be made to reach the IC tag.
[0078] 上述してきたように、本実施例 2では、パレットを挟んで相対する位置に配置したァ ンテナ Xおよびアンテナ Yから順に ICタグ読取用電波を発射することとしたので、片 方のアンテナからの ICタグ読取用電波が電波障害物の作用によって到達できない I Cタグに対しても別のアンテナ力 ICタグ読取用電波を到達させることができる。  [0078] As described above, in the second embodiment, since the IC tag reading radio wave is emitted in order from the antenna X and the antenna Y arranged at opposite positions across the pallet, one antenna is used. IC tag reading radio waves from can not reach due to the action of radio wave obstructions Even for IC tags, another antenna force IC tag reading radio waves can reach.
