発明の開示
発明が解決しょうとする課題
[0003] 単方向通信方式のタグ装置では、コマンドを無線受信して周辺機器を駆動したり、 周辺機器の状態を報告することが出来ない問題点がある。
他方、双方向通信方式のタグ装置では、単方向通信方式に比べて通信時間が長 くなるため、規定空間内に置かれるタグ装置の個数が増えるとコリジョンが生じやすく なって無線通信の確立が困難となる問題点がある。
そこで、本発明の目的は、周辺機器の駆動と周辺機器の状態告知が行え、コリジョ ンの防止が行えるタグ装置、トランシーバ装置およびタグシステムを提供することにあ る。
課題を解決するための手段
[0004] 第 1の観点では、本発明は、第 1の周波数の RF送信部（11)と、第 2の周波数の RF 送受信部（12)と、情報処理部（13)とを具備し、前記情報処理部（13)は、前記 RF 送信部（11)により定期的に IDを送信すると共に前記 RF送受信部（12)によりコマン ドの受信やユーザ IDの送信を行うことを特徴とするタグ装置（10)を提供する。 上記第 1の観点によるタグ装置（10)では、定期的な IDの送信を RF送信部（11)に より単方向通信方式で行うため、通信時間が短くて済み、規定空間内に置かれるタ グ装置（10)の個数が増えてもコリジョンが生じにくくなり無線通信の確立が容易にな る。また、 RF送受信部（12)による双方向通信方式でコマンドの受信やユーザ IDの 送信を行うことが出来るので、周辺機器を駆動したり、周辺機器の状態を報告するこ とが出来る。なお、 RF送信部（11)と RF送受信部（12)とは周波数が異なるため、重 なってもコリジョンは生じない。さらに、単方向通信の頻度よりも双方向通信の頻度を 減らせば、タグ装置（10)に内蔵した電池の寿命を延ばすことも出来る。
[0005] 第 2の観点では、本発明は、第 1の周波数の RF受信部（21)と、第 2の周波数の RF 送受信部（22)と、情報処理部（23)とを具備し、前記情報処理部（23)は、前記 RF 受信部（21)により IDを受信すると共に前記 RF送受信部（22)によりコマンドの送信 やユーザ IDの受信を行うことを特徴とするトランシーバ装置 (20)を提供する。
上記第 2の観点によるトランシーバ装置（20)では、前記第 1の観点によるタグ装置 ( 10)からの IDを RF受信部（21)により単方向通信方式で受信するため、通信時間が 短くて済み、規定空間内に置かれるタグ装置（10)の個数が増えてもコリジョンが生じ に《なり無線通信の確立が容易になる。また、 RF送受信部（22)による双方向通信 方式でコマンドの送信やユーザ IDの受信を行うことが出来るので、タグ装置（10)側 の周辺機器を駆動したり、周辺機器の状態を調べたりことが出来る。なお、単方向通 信と双方向通信とは周波数が異なるため、重なっても支障はない。
[0006] 第 3の観点では、本発明は、前記第 1の観点によるタグ装置（10)力 第 1の周波数 で定期的に IDを送信し、前記第 2の観点によるトランシーバ装置（20)で前記 IDを受 信すると前記トランシーバ装置（20)力もその上位装置 (H)に IDを報告し、前記トラン シーバ装置（20)がその上位装置 (H)力もコマンドを受け取ると第 2の周波数でコマ ンドを送信し、前記タグ装置（10)が前記コマンドを受信すると該コマンドに応じた処 理を行うことを特徴とするタグシステム（100)を提供する。
上記第 3の観点によるタグシステム（100)では、定期的な IDの送信を単方向通信 方式で行うため、通信時間が短くて済み、規定空間内に置かれるタグ装置（10)の個 数が増えてもコリジョンが生じに《なり無線通信の確立が容易になる。また、コマンド の送受信やユーザ IDの送受信を双方向通信方式で行うことが出来るから、タグ装置 (10)側の周辺機器を駆動したり、周辺機器の状態を調べたりすることが出来る。なお 、単方向通信と双方向通信とは周波数が異なるため、重なっても支障はない。さらに 、単方向通信の頻度よりも双方向通信の頻度を減らせば、タグ装置（10)に内蔵した 電池の寿命を延ばすことも出来る。
発明の効果
[0007] 本発明のタグ装置、トランシーバ装置およびタグシステムによれば、規定空間内に 置かれるタグ装置の個数が増えてもコリジョンが生じにくくなり無線通信の確立が容 易になる。また、コマンドの送受信やユーザ IDの送受信を双方向通信方式で行うこと が出来るから、タグ装置側の周辺機器を駆動したり、周辺機器の状態を調べたりする ことが出来る。なお、単方向通信と双方向通信とは周波数が異なるため、重なっても 支障はない。さらに、単方向通信の頻度よりも双方向通信の頻度を減らすことも可能 であるため、タグ装置に内蔵した電池の寿命を延ばすことも出来る。
発明を実施するための最良の形態
[0008] 以下、図に示す実施の形態により本発明をさらに詳細に説明する。なお、これによ り本発明が限定されるものではない。
実施例 1
[0009] 図 1は、実施例 1にかかるタグ装置 10を示す構成図である。
このタグ装置 10は、第 1の周波数 fl (例えば 303.825MHz)の RF送信部 11と、第 2の周波数 f2 (例えば 315MHz)の RF送受信部 12と、情報処理部 13と、情報処理 部 13に接続された周辺機器 4とを具備して 、る。
周辺機器 4は、操作スィッチ 1, LED2およびブザー 3である。
[0010] 図 2は、タグ装置 10の外観図である。
ケース 5に、操作スィッチ 1, LED2およびブザー 3が設置されている。
[0011] 図 3は、実施例 1にかかるトランシーバ装置 20を示す構成図である。
このトランシーバ装置 20は、第 1の周波数 fl (例えば 303.825MHz)の RF受信部 21と、第 2の周波数 f 2 (例えば 315MHz)の RF送受信部 22と、情報処理部 23ととを 具備している。 情報処理部 13は、ホストコンピュータのごとき上位装置 (H)に接続されている。
[0012] 図 4は、実施例 1にかかるタグシステム 100を示す構成図および単方向通信のタイミ ングチャートである。
このタグシステム 100は、複数（図示は 1台だけ）のタグ装置 10と、トランシーバ装置
20と力 構成されている。
タグ装置 10の情報処理部 13は一定時間 T (例えば 5秒間）毎に IDを送信するよう に RF送信部 11に指示し、 RF送信部 11は周波数 f 1で IDを電波送信する。
[0013] トランシーバ装置 20の RF受信部 21は第 1の周波数 flで IDを電波受信すると、受 信した IDを情報処理部 23に渡す。情報処理部 23は、 IDを上位装置 Hに報告する。
[0014] 図 5は、タグシステム 100における双方向通信のタイミングチャートである。
上位装置 Hは、トランシーバ装置 20から IDを報告されると、当該 ID宛コマンドがあ る力検索し、あれば該 ID宛コマンドをトランシーバ装置 20に送る。
[0015] トランシーバ装置 20の情報処理部 23は、上位装置 Hから ID宛コマンドが送られて きたなら、当該 ID宛コマンドを送信するように RF送受信部 22に指示し、 RF送受信部
22は第 2の周波数 f2で当該 ID宛コマンドを電波送信する。
[0016] タグ装置 10の RF送受信部 12は第 2の周波数 f2でコマンドを電波受信すると、受 信したコマンドを情報処理部 13に渡す。情報処理部 13は、コマンドが自 ID宛でない なら破棄し、自 ID宛なら当該コマンドによる処理を行う。ここで処理が例えば「操作ス イッチ 1の状態を報告せよ」である場合、情報処理部 13は、操作スィッチ 1の状態をス キャンし、それをユーザ IDに書き込み、そのユーザ IDを送信するように RF送受信部
12に指示し、 RF送受信部 12は周波数 f 2でユーザ IDを電波送信する。
[0017] トランシーバ装置 20の RF送受信部 22は第 2の周波数 f2でユーザ IDを電波受信 すると、受信したユーザ IDを情報処理部 23に渡す。情報処理部 23は、ユーザ IDを 上位装置 Hに報告する。
[0018] 上位装置 Hは、トランシーバ装置 20からユーザ IDを報告されると、当該 ID宛コマン ドがある力検索し、あれば該 ID宛コマンドをトランシーバ装置 20に送る。
[0019] トランシーバ装置 20の情報処理部 23は、上位装置 Hから ID宛コマンドが送られて きたなら、当該 ID宛コマンドを送信するように RF送受信部 22に指示し、 RF送受信部 22は第 2の周波数 f2で当該 ID宛コマンドを電波送信する。
[0020] タグ装置 10の RF送受信部 12は第 2の周波数 f2でコマンドを電波受信すると、受 信したコマンドを情報処理部 13に渡す。情報処理部 13は、コマンドが自 ID宛でない なら破棄し、自 ID宛なら当該コマンドによる処理を行う。ここで処理が例えば「LED2 を点灯し、ブザー 3を鳴らせ」である場合、情報処理部 13は、 LED2を点灯し、ブザ 一 3を鳴らす。そして処理済みの旨をユーザ IDに書き込み、そのユーザ IDを送信す るように RF送受信部 12に指示し、 RF送受信部 12は周波数 f 2でユーザ IDを電波送 信する。
[0021] トランシーバ装置 20の RF送受信部 22は第 2の周波数 f2でユーザ IDを電波受信 すると、受信したユーザ IDを情報処理部 23に渡す。情報処理部 23は、ユーザ IDを 上位装置 Hに報告する。
[0022] 実施例 1のタグシステム 100によれば次の効果が得られる。
(1)定期的な IDの送受信を単方向通信方式で行うため、通信時間が短くて済み、規 定空間内に置かれるタグ装置 10の個数が増えてもコリジョンが生じに《なり、無線 通信の確立が容易になる。
(2)コマンドの送受信やユーザ IDの送受信を双方向通信方式で行うから、周辺機器 4を駆動したり、周辺機器 4の状態を調べたりすることが出来る。
(3)単方向通信と双方向通信とは周波数が異なるため、重なっても支障はない。
(4) RF送信部 11は定期的な単方向通信の短い通信時間の間だけ動作し他の時間 は休止し、 RF送受信部 12は単方向通信より頻度の少ない双方向通信の間だけ動 作し他の時間は休止するので、タグ装置 10に内蔵した電池の寿命を延ばすことが出 来る。
[0023] (5)単方向通信の直後に同一 IDに対する双方向通信が行われるので、タグ装置 10 では単方向通信の直後の短時間だけ送受信部 12を動作させ、自 IDに対するコマン ドを受信すれば動作を継続し、自 IDに対するコマンドを受信しなければ休止させるこ とが出来る。これにより、タグ装置 10に内蔵した電池の寿命を延ばすことが出来る。 なお、タグ装置 10で単方向通信の直後の短時間だけ送受信部 12を動作させること を毎回行ってもよいが、間欠的（例えば単方向通信の 1回飛び毎）に行えばタグ装置 10に内蔵した電池の寿命をより延ばすことが出来る。
産業上の利用可能性
[0024] 本発明のタグ装置、トランシーバ装置およびタグシステムは、資産検索 (棚卸）シス テムやアンケート集計システムやオークションシステムに利用できる。
