Description
本発明は、非接触通信を行うＲＦＩＤタグ及びこれを用いた物品管理システムに関する。 The present invention relates to an RFID tag that performs non-contact communication and an article management system using the RFID tag.
本発明は、上述したような従来の技術が有する問題点に鑑みてなされたものであって、電源の消費を低減しながらも必要時に非接触通信が可能な状態とするＲＦＩＤタグ及びこれを用いた物品管理システムを提供することを目的とする。 The present invention has been made in view of the problems of the conventional technology as described above, and uses an RFID tag that enables non-contact communication when necessary while reducing power consumption . An object of the present invention is to provide an article management system .
このように、通信部が、コマンド信号に応じて第１のモードと第２のモードと第３のモードとに遷移することにより、周囲環境に応じて電源の消費を制御することができる。また、通信部がコマンド信号を受信できない第３のモードの状態においては、検出手段にて所定の操作が検出された場合、通信部が第１のモードと第２のモードとのいずれかに遷移し、コマンド信号を受信できる状態となるので、ＲＦＩＤタグに対して非接触通信を開始する際に行われる操作を所定の操作とすることにより、通信部がコマンド信号を受信できない第３のモードの状態であっても、必要時に非接触通信が可能な状態となる。
また、前記ＲＦＩＤタグを用いた物品管理システムとして、
前記通信部が前記第２のモードの状態のＲＦＩＤタグに対して、前記通信部を前記第１のモードに変更するためのコマンド信号を送信し、該コマンド信号を受信することで前記通信部が前記第１のモードとなったＲＦＩＤから、当該ＲＦＩＤに記憶された情報を取得し、その後、当該ＲＦＩＤに対して前記通信部を前記第３のモードに変更するためのコマンド信号を送信する第１の通信手段と、
前記所定の操作が検出されることで前記通信部が前記第３のモードから前記第１のモードに遷移したＲＦＩＤから、当該ＲＦＩＤに記憶された情報を取得する第２の通信手段と、
前記第１及び第２の通信手段にて取得された情報を用いて、当該ＲＦＩＤが取り付けられた物品を管理する管理手段とを有するものも考えられる。
Thus, the communication unit can control the power consumption according to the surrounding environment by changing to the first mode, the second mode, and the third mode according to the command signal. In the state of the third mode in which the communication unit cannot receive the command signal, the communication unit transitions to either the first mode or the second mode when a predetermined operation is detected by the detection unit. Since the command signal can be received, the operation performed when the contactless communication with the RFID tag is started is set as a predetermined operation, so that the communication unit cannot receive the command signal. Even if it is in a state, non-contact communication is possible when necessary.
In addition, as an article management system using the RFID tag,
The communication unit transmits a command signal for changing the communication unit to the first mode to the RFID tag in the state of the second mode, and receives the command signal so that the communication unit First, the information stored in the RFID is acquired from the RFID in the first mode, and then a command signal for changing the communication unit to the third mode is transmitted to the RFID. Communication means of
Second communication means for acquiring information stored in the RFID from the RFID in which the communication unit has transitioned from the third mode to the first mode by detecting the predetermined operation;
It is also conceivable to have management means for managing an article to which the RFID is attached, using information acquired by the first and second communication means.
保冷箱５０が搬入、開梱される搬入拠点７０には、受付エリア７１と搬入開梱エリア７２とが設けられており、これら受付エリア７１と搬入開梱エリア７２のそれぞれにおいても、ＲＦＩＤタグ１０との間にて非接触通信によって信号の送受信をすることで情報を読み出すリーダ７３，７４と、データセンタ８０に接続可能な通信装置７５，７６とが配置されている。なお、リーダ７３と通信装置７５とから第１の通信手段が構成され、リーダ７４と通信装置７６とから第２の通信手段が構成される。 A receiving area 71 and a loading / unpacking area 72 are provided at a loading base 70 where the cold box 50 is loaded and unpacked. The RFID tag 10 is also provided in each of the receiving area 71 and the loading / unpacking area 72. Readers 73 and 74 for reading information by transmitting and receiving signals by non-contact communication with the communication center 75 and communication devices 75 and 76 connectable to the data center 80 are arranged. The reader 73 and the communication device 75 constitute a first communication means, and the reader 74 and the communication device 76 constitute a second communication means.
データセンタ８０は、保冷箱５０の搬送状況を管理する管理手段となる拠点であって、通信装置６２，７５，７６と接続可能な通信装置８１が設けられるとともに、保冷箱５０の搬送状況が記憶されるデータベース８２を有している。 The data center 80 is a base serving as a management means for managing the conveyance status of the cold box 50, and is provided with a communication device 81 that can be connected to the communication devices 62, 75, and 76, and stores the conveyance status of the cold box 50. The database 82 is stored.
