データタグ５の電池を交換した場合、データタグ５における初期化処理として、パーソナルタグ４との通信回数ｎ（ｐ）、及び観察機３との通信回数ｎ（ｏ）がゼロに設定される。また、待機時消費電力Ｐｏｆｆ、パーソナルタグとの通信消費電力Ｐｏｎ（Ｐ）、観察機との通信消費電力Ｐｏｎ（ｏ）、及び電池最大容量Ｐｍａｘは初期設定データとして、サーバ２から、観察機３又はパーソナルタグ４を経由してデータタグ５に送られる。電池残量Ｐｒｅｓｔ、駆動時間Ｔ_５は、図示しないタイマで通信時間がカウントされて、通信のたびに更新される。
【００３２】
図３は、データタグ５の動作フローチャートを示している。データタグ５は通常、パーソナルタグ４又は観察機３からの受信待ち状態である。データタグ５が、パーソナルタグ４からの信号を受信すると（ステップＳ３０１でＹｅｓと判断されると）、パーソナルタグ４との通信回数ｎ（ｐ）に１が加えられ、駆動時間Ｔ_５が更新される（ステップＳ３０２）。
【００３３】
また、データタグ５が、観察機３からの信号を受信すると（ステップＳ３０３でＹｅｓと判断されると）、観察機３との通信回数ｎ（ｏ）に１が加えられ、駆動時間Ｔ_５が更新される（ステップＳ３０４）。
【００３４】
続いて、データタグ５の保有データから電池残量Ｐｒｅｓｔが算出される（ステップＳ３０５）。
【００３５】
すなわち、この電池残量Ｐｒｅｓｔは、
Ｐｒｅｓｔ＝Ｐｍａｘ−（ｎ（ｐ）＊Ｐｏｎ（Ｐ）＋ｎ（ｏ）＊Ｐｏｎ（ｏ）＋Ｔ_５＊Ｐｏｆｆ）
により求められる。
【００３６】
次に、このデータタグ５のタグＩＤと、算出された電池残量Ｐｒｅｓｔとが、パーソナルタグ４又は観察機３に送信され（ステップＳ３０６）、通信が完了する。
【００３７】
【表２】

表２は、パーソナルタグ４に設けられたメモリ４２データ構成例を示している。各パーソナルタグ４のタグＩＤは、メモリ４２上に初期データとして与えられたハードウェアに固有の値である。
【００３８】
パーソナルタグ４の電池を交換した場合、パーソナルタグ４における初期化処理として、データタグ５との通信回数ｎ（ｄ）、観察機３との通信回数ｎ（ｏ）がゼロに設定される。また、待機時消費電力Ｐｏｆｆ、データタグ５との通信消費電力Ｐｏｎ（ｄ）、観察機３との通信消費電力Ｐｏｎ（ｏ）、電池最大容量Ｐｍａｘは、初期設定データとしてサーバ２から観察機３を経由してパーソナルタグ４に送られる。電池残量Ｐｒｅｓｔ、及び駆動時間Ｔ_４は、通信のたびに更新される。
【００３９】
また、パーソナルタグ４は、データタグ５との通信履歴を残すために、図４に示すようなデータタグ情報を記録するデータシート４５を保有している。図中、記号ＤｎはデータタグＩＤを示し、データタグＩＤは初期化処理時にサーバ２から与えられる。通信の有無を示す通信チェックフラグＣｆ（Ｄｎ）や、通信時刻Ｔｃｏｍ（Ｄｎ）、及び電力残量Ｐｃｏｍ（Ｄｎ）は、対象となるデータタグ５と通信した際に更新される。
【００４０】
図５はパーソナルタグ４の動作フローチャートを示している。パーソナルタグ４は通常、通信信号を発信し続けており、データタグ５又は観察機３からの応答があるかどうかを確認している。
【００４１】
パーソナルタグ４が、データタグ５と通信を確認すると（ステップＳ５０１でＹｅｓと判断されると）、データタグ５との通信回数ｎ（ｄ）に１が加えられる（ステップＳ５０２）。
【００４２】
続いて、パーソナルタグ４は、通信の確立したデータタグ５からのタグＩＤ、電池残量Ｐｒｅｓｔを受信する（ステップＳ５０３）。そして、データシート４５上において、受信したデータタグ５のタグＩＤと合致する「Ｄｎ」のデータ行の電力残量Ｐｃｏｍ（Ｄｎ）に電池残量Ｐｒｅｓｔを代入し、通信時刻Ｔｃｏｍ（Ｄｎ）に時刻を入力するとともに、通信チェックフラグＣｆ（Ｄｎ）に１を代入する（ステップＳ５０４）。これにより、パーソナルタグ４は、通信を行ったデータタグ５のデータを記録・更新する。
【００４３】
一方、パーソナルタグ４が、観察機３との通信を確認すると（ステップＳ５０５でＹｅｓと判断されると）、観察機３との通信回数ｎ（ｏ）をインクリメントし、図示しないタイマ等によりパーソナルタグ４の駆動時間Ｔ_４が更新される（ステップＳ５０６）。
【００４４】
続いて、データタグ５との通信消費電力Ｐｏｎ（ｄ）、データタグ５との通信回数ｎ（ｄ）、観察機３との通信消費電力Ｐｏｎ（ｏ）、観察機３との通信回数ｎ（ｏ）、駆動時間Ｔ_４、及び待機時消費電力Ｐｏｆｆにより、パーソナルタグ４における電池残量Ｐｒｅｓｔが算出される（ステップＳ５０７）。
【００４５】
すなわち、この電池残量Ｐｒｅｓｔは、
Ｐｒｅｓｔ＝Ｐｏｎ（ｄ）＊ｎ（ｄ）＋Ｐｏｎ（ｏ）＊ｎ（ｏ）＋Ｔ_４＊Ｐｏｆｆ
により求められる。
【００４６】

続いて、送信したＤｎ＝１であった行のデータについて、通信チェックフラグＣｆ（Ｄｎ）＝０、Ｔｃｏｍ（Ｄｎ）＝ＮＵＬＬ（値なし）、Ｐｃｏｍ（Ｄｎ）＝ＮＵＬＬ（値なし）を代入する（ステップＳ５０９）。
【００４８】
以上の処理によって、パーソナルタグ４は、メモリ４２上に蓄積した自己のデータとデータタグ５のデータとを観察機３を介してサーバ２に送信する。
【００４９】
【表３】

表３は、サーバ２が保有するデータ構成例を示している。
【００５０】
サーバ２が保有する各データのうち、データタグ５の電池最大容量Ｐｍａｘ（ｄ）、データタグ５の待機時消費電力Ｐｏｆｆ（ｄ）、データタグ５のパーソナルタグ４との通信消費電力Ｐｏｎ（ｄ）（ｐ）、データタグ５における観察機３との通信消費電力Ｐｏｎ（ｄ）（ｏ）、パーソナルタグ４の電池最大容量Ｐｍａｘ（ｐ）、パーソナルタグ４の待機時消費電力Ｐｏｆｆ（ｐ）、パーソナルタグ４のデータタグ５との通信消費電力Ｐｏｎ（ｐ）（ｄ）、パーソナルタグ４における観察機３との通信消費電力Ｐｏｎ（ｐ）（ｏ）、データタグ５の消費電力警告閾値Ｐｔｈ（ｄ）、及びパーソナルタグ４の消費電力警告閾値Ｐｔｈ（ｐ）は、システム初期化時にユーザ９又はシステム管理者によって設定された初期データファイルから読み込まれる。また、現時刻Ｔｎｏｗは、図示しないタイマにより常に更新されている。
【００５１】
また、サーバ２は図６に示すような、パーソナルタグ４及びデータタグ５の情報を保有するためのデータシート２５を保有している。図中、記号Ｐｎは、パーソナルタグ４のタグＩＤを示す。このデータシート２５には、パーソナルタグ４に関するタグ名称Ｎａｍｅ（Ｐｎ）、予想電力残量Ｐｒｅｓｔ（Ｐｎ）、前通信時からの経過時間Ｔｐａｓｓ（Ｐｎ）、通信時電力残量Ｐｃｏｍ（Ｐｎ）、及び通信動作時刻Ｔｃｏｍ（Ｐｎ）のデータが記録される。また、データタグ５に関しても同様のデータが記録される。
【００５２】
このデータシート２５上のデータのうち、パーソナルタグ４のタグ名称Ｎａｍｅ（Ｐｎ）、及びデータタグ５のタグ名称Ｎａｍｅ（Ｄｎ）は、ユーザ９により設定される。また、これらのタグ名称以外のデータは、観察機３を経由して得られたパーソナルタグ４のデータ、又はデータタグ５のデータによって更新される。
【００５３】
図７は、サーバ２の動作フローチャートを示している。
【００５４】
前記したように、パーソナルタグ４が観察機３と通信を行うと（ステップＳ７０１でＹｅｓと判断されると）、サーバ２は観察機３を通じてパーソナルタグ４及びデータタグ５のデータを受信する。そして、サーバ２のデータシート２５上において、受信したパーソナルタグ４のタグＩＤと合致する「Ｐｎ」のデータ行の通信動作時刻Ｔｃｏｍ（Ｐｎ）に時刻を入力し、通信時電力残量Ｐｃｏｍ（Ｐｎ）に電池残量Ｐｒｅｓｔを代入する。さらに、受信したデータタグ５のタグＩＤと合致する「Ｄｎ」のデータ行の通信動作時刻Ｔｃｏｍ（Ｄｎ）欄、及び通信時電力残量Ｐｃｏｍ（Ｄｎ）欄に受信したデータを代入する（ステップＳ７０２）。
【００５５】
次に、現時刻Ｔｎｏｗと、パーソナルタグ４の通信動作時刻Ｔｃｏｍ（Ｐｎ）との差分を、前通信時からの経過時間Ｔｐａｓｓ（Ｐｎ）に入力する。同様に、現時刻Ｔｎｏｗと、データタグ５の通信動作時刻Ｔｃｏｍ（Ｄｎ）との差分を、前通信時からの経過時間Ｔｐａｓｓ（Ｄｎ）に入力する（ステップＳ７０３）。
【００５６】
続いて、これらの前通信時からの経過時間Ｔｐａｓｓ（Ｐｎ），Ｔｐａｓｓ（Ｐｎ）を用いて、パーソナルタグ４及びデータタグ５のそれぞれににおける予想電力残量Ｐｒｅｓｔ（Ｐｎ），Ｐｒｅｓｔ（Ｄｎ）を計算する（ステップＳ７０４）。各予想電力残量Ｐｒｅｓｔ（Ｐｎ），Ｐｒｅｓｔ（Ｄｎ）は、前通信時からの経過時間Ｔｐａｓｓ（Ｐｎ），Ｔｐａｓｓ（Ｄｎ）に各タグ４，５の待機時消費電力Ｐｏｆｆ（Ｐｎ），Ｐｏｆｆ（Ｄｎ）を乗した値を、通信時電力残量Ｐｃｏｍ（Ｐｎ），Ｐｃｏｍ（Ｄｎ）から差し引いて求められる。
【００５７】
次に、パーソナルタグ４とデータタグ５に警告するための各消費電力警告閾値Ｐｔｈ（ｐ），Ｐｔｈ（ｄ）と、データシート２５上の各予想電力残量Ｐｒｅｓｔ（Ｐｎ），Ｐｒｅｓｔ（Ｄｎ）を比較して、各消費電力警告閾値Ｐｔｈ（ｄ），Ｐｔｈ（ｄ）を下回るタグＩＤ「Ｐｎ」、「Ｄｎ」があるかどうかが判定される（ステップＳ７０５）。
【００５８】
パーソナルタグ４又はデータタグ５に、該当するタグＩＤ「Ｐｎ」、「Ｄｎ」があると（ステップＳ７０５でＹｅｓと判断されると）、メッセージバッファに「Ｐｎ」、「Ｄｎ」の各タグ名称Ｎａｍｅ（Ｐｎ），Ｎａｍｅ（Ｄｎ）、及び電力残量警告メッセージが追加される（ステップＳ７０６）。
【００５９】
続いて、メッセージバッファに警告メッセージがあるかどうかが確認され（ステップＳ７）、警告メッセージがあると（ステップＳ７０７でＹｅｓと判断されると）、情報端末装置１においてメッセージを表示するように情報端末装置１にデータが送信される（ステップＳ７０８）。
【００６０】
以上の処理によって、ユーザ９の生活情報が取得されると、同時にパーソナルタグ４及びデータタグ５における各予想電力残量Ｐｒｅｓｔ（Ｐｎ），Ｐｒｅｓｔ（Ｄｎ）を管理して、これらが設定された値以下になった場合はユーザ９に対して警告を出すものとなる。ユーザ９は、情報端末装置１に表示されたメッセージを見ることで、電池交換が必要なパーソナルタグ４及びデータタグ５を認識し、適宜電池を取り替えることができる。この結果、電池切れによるユーザ９の生活情報の取りこぼしがなくなる。
【００６１】
また、データタグ５が保持するデータをユーザ９が要求したとき、あるいは定期的に要求するようにプログラムした場合には、パーソナルタグ４による各データの更新がなくてもデータタグ５の電力残量の確認をすることができる。図８は、このような場合のサーバ２における動作フローチャートを示している。
【００６２】
まず、ユーザ９あるいはプログラムによってデータタグ５に対し返信要求信号が送信される（ステップＳ８０１）。このとき、データタグ５における処理は、図３に示した動作と同様である。データタグ５からの返信を受信すると（ステップＳ８０２でＹｅｓと判断されると）、データシート２５上において、受信したデータタグ５のタグＩＤと合致するタグＩＤ「Ｄｎ」のデータ行の通信動作時刻Ｔｃｏｍ（Ｄｎ）に時刻を入力し、通信時電力残量Ｐｃｏｍ（Ｄｎ）に受信した電池残量Ｐｒｅｓｔを代入する（ステップＳ８０３〜Ｓ８０４）。以後の処理（ステップＳ８０５〜Ｓ８１０）は、前記と同様である。
【００６３】
以上説明した生活情報管理システムは、パーソナルタグ、データタグ、及び観察機とを用いて、管理対象物を管理するとともに、これらの電力残量を管理する処理を機能させるためのプログラムで実現されている。

About.
[0002]
[Prior art]
Human life is surrounded by many things, but each action is thought to be related only to a specific one of them. Therefore, if the living information is appropriately managed, useless operations can be eliminated when searching for an object to be managed, and the user can act efficiently. In addition, it becomes easy to collect information on human behavior. Here, the living information refers to, for example, information on a storage location and an operation state of the management target object, information on a person's location and its behavior, and the like.
[0003]
Conventionally, a technique described in Patent Literature 1 has been proposed to manage such living information. The behavior determination device disclosed in Patent Document 1 detects the behavior of a subject using a CCD camera, an infrared sensor, or the like, and further turns on / off a power supply of a television, opens and closes a refrigerator door, and the like. The operation of various devices can be detected. Further, a combination pattern of the operation of these devices and the behavior of the target person is recorded in the behavior determination device in advance. The behavior determination device compares such a combination pattern with the actually detected behavior of the target person and the operation of the device to determine the behavior of the target person. If the combination pattern does not match the detection result, a warning is output.
[0004]
However, in such a behavior determination device, means for acquiring behavior data (user data) of a target person by using several kinds of fixed sensors is not uniform, and lacks versatility.
[0005]
In order to solve such a problem, the present applicant has a versatility for a management target object, a living information management system capable of efficiently detecting the management target object and managing various information in a human living environment. A system was developed (Japanese Patent Application No. 2002-032727).
[0006]
FIG. 9 shows an example of an arrangement state of the living information management system. The living information management system is installed, for example, in the residence of the subject (user 9) who manages living information. The user 9 has a device (personal tag 4) for acquiring his / her own living information, and attaches a device (data tag 5) for acquiring the information to an object or place to be managed. In the living room, a server 2 that stores the action history of the user 9 and performs data processing is also installed. Further, in the living room, a communication device (observation device 3) that communicates with the personal tag 4 and obtains life information of the user 9 is installed. Then, the server 2 communicates with the personal tag 4 to accumulate the action history data of the user 9 and give an instruction to the personal tag 4. Further, the user 9 inputs information of the management target into the information terminal device 1 to give an instruction, and receives the result from the information terminal device 1.

[Problems to be solved by the invention]
In the living information management system, the personal tag and the data tag are reduced in size and weight so as to be portable or attachable to any place or article. For this reason, a battery is used to drive each tag. However, in the above-described system, since the remaining battery level in each tag cannot be checked, communication is not possible when the batteries are exhausted, and as a result, there is a possibility that the user's life information cannot be recorded.
[0009]
In the above-mentioned system, the occurrence of such a problem due to running out of the battery is prevented by periodically replacing the battery of each tag. However, the power consumption naturally differs depending on the number of times of communication of each tag.

[Table 1]

Table 1 shows a data configuration example of the memory 52 provided in the data tag 5. The tag ID of each data tag 5 is a hardware-specific value given as initial data on the memory.
[0031]
When the battery of the data tag 5 is replaced, the number of communications n (p) with the personal tag 4 and the number of communications n (o) with the observation device 3 are set to zero as initialization processing in the data tag 5. The standby power consumption Poff, the communication power consumption Pon (P) with the personal tag, the communication power consumption Pon (o) with the observation device, and the battery maximum capacity Pmax are set as initial setting data from the server 2 to the observation device 3. Alternatively, the data is sent to the data tag 5 via the personal tag 4. Battery remaining time Prest, driving time T ₅ The communication time is counted by a timer (not shown), and is updated each time communication is performed.
[0032]
FIG. 3 shows an operation flowchart of the data tag 5. The data tag 5 is usually in a state of waiting for reception from the personal tag 4 or the observation device 3. When the data tag 5 receives a signal from the personal tag 4 (determined as Yes in step S301), 1 is added to the number n (p) of communications with the personal tag 4, and the driving time T ₅ Is updated (step S302).
[0033]
Further, when the data tag 5 receives the signal from the observation device 3 (determined as Yes in step S303), 1 is added to the number of communications n (o) with the observation device 3, and the driving time T ₅ Is updated (step S304).
[0034]
Subsequently, the remaining battery power Prest is calculated from the data held in the data tag 5 (step S305).
[0035]
That is, this battery remaining amount Prest is
Prest = Pmax- (n (p) * Pon (P) + n (o) * Pon (o) + T ₅ * Poff)

[0036]
Next, the tag ID of the data tag 5 and the calculated remaining battery power Prest are transmitted to the personal tag 4 or the observation device 3 (step S306), and the communication is completed.
[0037]
[Table 2]

Table 2 shows a data configuration example of the memory 42 provided in the personal tag 4. The tag ID of each personal tag 4 is a value unique to hardware given as initial data on the memory 42.
[0038]
When the battery of the personal tag 4 is replaced, the number of communication n (d) with the data tag 5 and the number of communication n (o) with the observation device 3 are set to zero as initialization processing in the personal tag 4. The standby power consumption Poff, the communication power consumption Pon (d) with the data tag 5, the communication power consumption Pon (o) with the observation device 3, and the battery maximum capacity Pmax are transmitted from the server 2 to the observation device 3 as initial setting data. Is sent to the personal tag 4 via. Battery remaining amount Prest and driving time T ₄ Is updated for each communication.
[0039]
The personal tag 4 has a data sheet 45 for recording data tag information as shown in FIG. 4 in order to leave a communication history with the data tag 5. In the figure, the symbol Dn indicates a data tag ID, and the data tag ID is given from the server 2 at the time of initialization processing. The communication check flag Cf (Dn) indicating the presence or absence of communication, the communication time Tcom (Dn), and the remaining power Pcom (Dn) are updated when communicating with the target data tag 5.
[0040]
FIG. 5 shows an operation flowchart of the personal tag 4. The personal tag 4 normally keeps transmitting a communication signal, and confirms whether or not there is a response from the data tag 5 or the observation device 3.
[0041]
When the personal tag 4 confirms communication with the data tag 5 (determined as Yes in step S501), 1 is added to the number of communication n (d) with the data tag 5 (step S502).
[0042]
Subsequently, the personal tag 4 receives the tag ID and the battery remaining amount Prest from the data tag 5 with which communication has been established (step S503). Then, in the data sheet 45, the remaining battery power Prest is substituted for the remaining power Pcom (Dn) of the data row of “Dn” that matches the tag ID of the received data tag 5, and the time is set as the communication time Tcom (Dn). Is input, and 1 is substituted for the communication check flag Cf (Dn) (step S504). As a result, the personal tag 4 records and updates the data of the data tag 5 with which the communication has been performed.
[0043]
On the other hand, when the personal tag 4 confirms communication with the observation device 3 (when it is determined as Yes in step S505), the personal tag 4 increments the number n (o) of communication with the observation device 3 and uses a timer (not shown) or the like to increment the personal tag. 4 driving time T ₄ Is updated (step S506).
[0044]
Subsequently, the power consumption Pon (d) of communication with the data tag 5, the number n (d) of communication with the data tag 5, the power consumption Pon (o) of communication with the observation device 3, and the number of communication n (n) with the observation device 3 o), drive time T ₄ And the standby power consumption Poff, the remaining battery power Prest in the personal tag 4 is calculated (step S507).
[0045]
That is, this battery remaining amount Prest is
Prest = Pon (d) * n (d) + Pon (o) * n (o) + T ₄ * Poff
Required by
[0046]
Next, the calculated remaining battery power Prest, the tag ID of the personal tag 4, the tag ID “Dn” of the row where the communication check flag Cf (Dn) = 1 on the data sheet 45, the communication time Tcom (Dn), and The remaining power Pcom (Dn) is transmitted (step S508).
[0047]
Subsequently, the communication check flag Cf (Dn) = 0, Tcom (Dn) = NULL (no value), and Pcom (Dn) = NULL (no value) are substituted for the transmitted data of the row where Dn = 1. (Step S509).
[0048]
Through the above processing, the personal tag 4 transmits its own data stored in the memory 42 and the data of the data tag 5 to the server 2 via the observation device 3.
[0049]
[Table 3]

Table 3 shows an example of a data configuration held by the server 2.
[0050]
Among the data held by the server 2, the maximum battery capacity Pmax (d) of the data tag 5, the standby power consumption Poff (d) of the data tag 5, and the communication power consumption Pon (d) of the data tag 5 with the personal tag 4. ) (P), power consumption Pon (d) (o) of communication with the observation device 3 in the data tag 5, maximum battery capacity Pmax (p) of the personal tag 4, standby power consumption Poff (p) of the personal tag 4, The power consumption Pon (p) (d) of communication of the personal tag 4 with the data tag 5, the power consumption Pon (p) (o) of communication of the personal tag 4 with the observation device 3, and the power consumption warning threshold Pth ( d) and the power consumption warning threshold value Pth (p) of the personal tag 4 are read from the initial data file set by the user 9 or the system administrator at the time of system initialization. It is. The current time Tnow is constantly updated by a timer (not shown).
[0051]
Further, the server 2 has a data sheet 25 for storing information of the personal tag 4 and the data tag 5 as shown in FIG. In the figure, the symbol Pn indicates the tag ID of the personal tag 4. The data sheet 25 includes a tag name Name (Pn) for the personal tag 4, an expected power remaining amount Prest (Pn), an elapsed time Tpass (Pn) from the previous communication, a communication power remaining amount Pcom (Pn), and Data of the communication operation time Tcom (Pn) is recorded. The same data is recorded for the data tag 5 as well.
[0052]
Of the data on the data sheet 25, the tag name Name (Pn) of the personal tag 4 and the tag name Name (Dn) of the data tag 5 are set by the user 9. The data other than the tag names is updated by the data of the personal tag 4 obtained via the observation device 3 or the data of the data tag 5.
[0053]
FIG. 7 shows an operation flowchart of the server 2.
[0054]
As described above, when the personal tag 4 communicates with the observation device 3 (determined as Yes in step S701), the server 2 receives the data of the personal tag 4 and the data tag 5 through the observation device 3. Then, on the data sheet 25 of the server 2, a time is input as the communication operation time Tcom (Pn) of the data line “Pn” that matches the tag ID of the received personal tag 4, and the remaining power during communication Pcom (Pn ) Is substituted for the battery remaining amount Prest. Further, the received data is assigned to the communication operation time Tcom (Dn) column and the communication remaining power amount Pcom (Dn) column of the data row of “Dn” that matches the tag ID of the received data tag 5 (step S702). ).
[0055]
Next, the difference between the current time Tnow and the communication operation time Tcom (Pn) of the personal tag 4 is input to the elapsed time Tpass (Pn) from the previous communication. Similarly, the difference between the current time Tnow and the communication operation time Tcom (Dn) of the data tag 5 is input to the elapsed time Tpass (Dn) from the previous communication (step S703).
[0056]
Subsequently, using the elapsed times Tpass (Pn) and Tpass (Pn) from the previous communication, the estimated remaining power levels Prest (Pn) and Prest (Dn) in the personal tag 4 and the data tag 5, respectively, are calculated. The calculation is performed (step S704). The estimated remaining power levels Prest (Pn) and Prest (Dn) are the standby power consumption Poff (Pn) and Poff (Poff (Pn) of the tags 4 and 5 during the elapsed times Tpass (Pn) and Tpass (Dn) from the previous communication. Dn) is obtained by subtracting the value raised to the power of Dcom from Pcom (Pn) and Pcom (Dn).
[0057]
Next, each power consumption warning threshold value Pth (p), Pth (d) for warning the personal tag 4 and the data tag 5 and each expected power remaining amount Prest (Pn), Prest (Dn) on the data sheet 25. Are compared, it is determined whether there are tag IDs “Pn” and “Dn” below the power consumption warning thresholds Pth (d) and Pth (d) (step S705).
[0058]
If the corresponding tag IDs “Pn” and “Dn” are present in the personal tag 4 or the data tag 5 (Yes in step S705), the tag names “Pn” and “Dn” are stored in the message buffer. (Pn), Name (Dn), and a remaining power warning message are added (step S706).
[0059]
Subsequently, it is confirmed whether or not there is a warning message in the message buffer (step S7). If there is a warning message (if Yes is determined in step S707), the information terminal 1 displays the message on the information terminal device 1 so as to display the message. The data is transmitted to the device 1 (Step S708).
[0060]
When the life information of the user 9 is acquired by the above-described processing, at the same time, the respective expected power remaining amounts Prest (Pn) and Prest (Dn) in the personal tag 4 and the data tag 5 are managed and set to the set values. In the following cases, a warning is issued to the user 9. The user 9 recognizes the personal tag 4 and the data tag 5 that require battery replacement by seeing the message displayed on the information terminal device 1, and can replace the battery as appropriate. As a result, missing of the life information of the user 9 due to running out of the battery is eliminated.
[0061]
When the user 9 requests the data held by the data tag 5 or when the user is programmed to request the data periodically, the remaining power of the data tag 5 can be obtained without updating the data by the personal tag 4. Can be confirmed. FIG. 8 shows an operation flowchart in the server 2 in such a case.
[0062]
First, a reply request signal is transmitted to the data tag 5 by the user 9 or a program (step S801). At this time, the processing in the data tag 5 is the same as the operation shown in FIG. When the reply from the data tag 5 is received (Yes in step S802), the communication operation time of the data row of the data ID 25 with the tag ID “Dn” that matches the tag ID of the received data tag 5 The time is input to Tcom (Dn), and the received battery remaining amount Prest is substituted for the communication power remaining amount Pcom (Dn) (steps S803 to S804). Subsequent processing (steps S805 to S810) is the same as described above.
