Description

本発明は利用者が携帯する無線端末機器の電力制御に関する。   The present invention relates to power control of a wireless terminal device carried by a user.

ユーザの動作を検出する機能として歩数計が知られている。また、加速度センサが搭載された携帯電話を歩数計として使うことも公知となっている。さらに、スポーツ選手に心拍計端末を携帯させ無線で遠隔監視することも公知である。歩数計などのセンサは基本的にユーザが常時使うことを前提としているためユーザ自身が手動で電源をオンオフしている。 A pedometer is known as a function for detecting a user's action. It is also well known to use a mobile phone equipped with an acceleration sensor as a pedometer. Furthermore, it is also known that a sports player carries a heart rate monitor terminal and performs remote monitoring wirelessly. Since sensors such as pedometers are basically assumed to be used by the user at all times, the user manually turns the power on and off.

携帯機器の電源を自動的にオンオフ制御することで省電力化を図る技術として加速度センサを用いることが知られている。特許文献１に開示されている技術は、加速度センサを用いて装置の動きを検出し、装置が動いていないときには省電力モードに入り、装置が動いたことを検出すると通常動作モードに移行することで、装置が使われていないときの省電力化を実現している。   It is known to use an acceleration sensor as a technique for saving power by automatically turning on / off a power source of a portable device. The technique disclosed in Patent Document 1 detects the movement of the apparatus using an acceleration sensor, enters the power saving mode when the apparatus is not moving, and shifts to the normal operation mode when it is detected that the apparatus has moved. Therefore, power saving is realized when the device is not used.

一方、特許文献２または３は端末の位置に基づいて無線通信機能をオンオフすることで、端末機器の省電力化を実現する技術を開示している。この公知技術によると端末がＧＰＳや車載ナビゲーションシステムで取得した位置情報と、通信相手である基地局の領域情報や自動料金収受システム（ＥＴＣ）の位置情報を比較し、通信相手の装置との距離が近く通信が可能である確率が高いと判断したときには無線インターフェースやＥＴＣ車載機などの無線通信機能をオンにし、通信相手との距離が遠く通信が可能である確率が低いと判断した場合には無線通信機能をオフにすることで省電力化を図っている。
特開２００７−１０２３７０ 特開２００２−２４６９７７ 特開２００３−３４６２０４ On the other hand, Patent Document 2 or 3 discloses a technique for realizing power saving of a terminal device by turning on and off a wireless communication function based on the position of the terminal. According to this known technology, the position information acquired by the terminal using GPS or an in-vehicle navigation system is compared with the area information of the communication partner base station or the position information of the automatic toll collection system (ETC), and the distance to the communication partner device If it is determined that there is a high probability that communication is possible, turn on the wireless communication function such as the wireless interface or ETC in-vehicle device, and if it is determined that there is a low probability that communication with a communication partner is far away Power saving is achieved by turning off the wireless communication function.

特許文献１は使われないときは静止している無線端末機器の省電力化は可能であるが、使われていないときもユーザが持ち歩くような無線端末機器の省電力化を実現することはできない。   Patent Document 1 can reduce the power consumption of a stationary wireless terminal device when it is not used, but cannot realize the power saving of a wireless terminal device that a user carries even when it is not being used. .

特許文献２は、センサ機能付きの端末機器に関するものではなく無線通信装置に関するものであり、無線通信機能のオンオフが通信相手の基地局の領域情報や設置位置を基に決定されている。そのため通信相手がいないセンサ機能の電源制御に適用することができない。殊に、本技術を無線端末機器のセンサ機能のオンオフに適用することを考えると、この端末機器が通信相手の基地局の領域内にいるときには常にセンサ機能がオンになるため省電力化はできない。   Patent Document 2 relates not to a terminal device with a sensor function but to a wireless communication apparatus, and on / off of the wireless communication function is determined based on area information and an installation position of a communication partner base station. Therefore, it cannot be applied to power control of a sensor function with no communication partner. In particular, considering that the present technology is applied to turning on and off the sensor function of a wireless terminal device, the power saving cannot be achieved because the sensor function is always turned on when the terminal device is in the area of the base station of the communication partner. .

さらに、センサ機能付き無線端末機器の電力消費の大部分はセンサが検出した情報を無線で送信する際に発生するため無線送信機能を効率的に使用し、無駄な送信を出来る限り少なくする必要がある。   Furthermore, since most of the power consumption of wireless terminal devices with sensor functions occurs when the information detected by the sensors is transmitted wirelessly, it is necessary to use the wireless transmission function efficiently and minimize unnecessary transmissions. is there.

Based on the area information, the determination results of the sensor driving range determination function 213 that determines whether or not the wireless terminal device 101 is within the area where the sensor function 204 is driven, the wireless range determination function 211, and the driving range determination function 213 And a power saving control function 212 for driving the sensor function 204 based on this.

When the terminal location management function exists on an external network, it is conceivable to acquire the location information of the terminal itself from the external location management function using wireless communication. For example, when entrance / exit to / from a specific area of a user holding a wireless terminal is managed by an entrance / exit management system or the like, it is conceivable to acquire location information of the wireless sensor terminal from the entrance / exit management system. Various sensors such as an acceleration sensor, a temperature sensor, and an illuminance sensor can be used as the sensor function.

図３は位置情報を赤外線により複数箇所から発信する例を示す。この例で、赤外線送信器３０１，３０２，３０３が互いに異なる位置ＩＤ情報を下方に向けて発信される。無線端末機器１０１は、位置情報取得機能として赤外線受信器を使用し、この無線端末が赤外線受信エリア３０４、３０５，３０６に順次入ると赤外線送信器３０１、３０２，３０３が発信する位置ＩＤを順次受信する。   FIG. 3 shows an example in which position information is transmitted from a plurality of locations by infrared rays. In this example, the infrared transmitters 301, 302, and 303 transmit different position ID information downward. The wireless terminal device 101 uses an infrared receiver as a position information acquisition function, and sequentially receives position IDs transmitted by the infrared transmitters 301, 302, and 303 when the wireless terminal sequentially enters the infrared reception areas 304, 305, and 306. To do.

図４は、実際の環境における無線通信エリアと赤外線受信エリアの設置例を示した図である。フロア４０１は２つの無線通信エリア４０２、４０３でカバーされ、さらに複数の赤外線受信エリア４０４でカバーされている。   FIG. 4 is a diagram showing an installation example of a wireless communication area and an infrared reception area in an actual environment. The floor 401 is covered with two wireless communication areas 402 and 403, and further covered with a plurality of infrared receiving areas 404.

図５にセンサ機能２０４を駆動するエリア情報を格納するメモリ２０５の構成を示す。センサ駆動エリアの情報は、２組の座標情報（ｘ１、ｙ１、ｘ２、ｙ２）で与えられる矩形エリアで管理する場合（５０１）、１組の座標情報（ｘ３、ｙ３）と１つの半径情報（ｒ１）で管理する場合（５０２）、接続する無線基地局の基地局番号などの情報で管理する場合（５０３、５０４）、位置情報取得用に設置される位置管理用ＩＤ番号で管理する場合（５０５、５０６）などが考えられる。また、これらの管理方法を複数併用してもよい。さらに、位置情報取得機能が赤外線受信器である場合、参照番号５０５が示すように位置情報として位置ＩＤ“００００１００１”がメモリ２０５に格納される。また、参照番号５０６は位置ＩＤの範囲「００００１２００」乃至「００００１２５０」を示す。また、参照番号５０７は「０００２」で始まる全ての位置ＩＤを表す赤外線位置情報を示している。   FIG. 5 shows a configuration of the memory 205 that stores area information for driving the sensor function 204. When the sensor drive area information is managed by a rectangular area given by two sets of coordinate information (x1, y1, x2, y2) (501), one set of coordinate information (x3, y3) and one radius information ( In the case of management in r1) (502), in the case of management by information such as the base station number of the connected radio base station (503, 504), in the case of management by the location management ID number installed for acquiring location information ( 505, 506) and the like. A plurality of these management methods may be used in combination. Further, when the position information acquisition function is an infrared receiver, a position ID “00000101” is stored in the memory 205 as position information as indicated by reference numeral 505. Reference numeral 506 indicates a range of position IDs “0000200” to “0000100250”. Reference numeral 507 indicates infrared position information representing all position IDs starting with “0002”.

図６は図２の無線端末機器１０１のＣＰＵが実行する処理の例を示すフローチャートである。無線圏内判定機能２１１は端末機器１０１が無線基地局の圏内であるか否かを判定し圏内であれば外部と通信が可能であると判定する（ステップ６０１）。ＣＰＵ２０１は無線基地局圏内ではないと判定するとステップ６０１の処理を連続的又は周期的に繰り返し実行する。無線基地局圏内であると判定すると（ステップ６０１のＹｅｓ）、ＣＰＵ２０１は位置情報取得機能２０３を用いて位置ＩＤ情報を受信する（ステップ６０２）。ＣＰＵ２０１はステップ６０３でメモリ２０５を参照し、受信した位置ＩＤが駆動圏内情報に該当するか否かを判定する。ＣＰＵ２０１は、無線端末１０１がセンサ駆動圏内にいると判定すると、無線端末１０１が引き続き無線基地局圏内に止まっているか否かをステップ６０４で判定し、無線基地局圏外であると判定した場合ステップ６０１に戻り、無線基地局圏内に引き続き止まっていると判定するとステップ６０５でセンサ機能２０４を駆動する。センサ機能２０４が得た情報は無線通信機能２０２を介し外部に送信される。ステップ６０５が実行されるとＣＰＵ２０１はステップ６０１に戻る。あるいは、一定時間センサ機能２０４を連続定期または周期的に駆動した後ステップ６０１に戻ってもよい。   FIG. 6 is a flowchart illustrating an example of processing executed by the CPU of the wireless terminal device 101 of FIG. The wireless range determination function 211 determines whether or not the terminal device 101 is within the range of the wireless base station, and determines that communication with the outside is possible if within range (step 601). If the CPU 201 determines that it is not within the radio base station range, it repeatedly executes the process of step 601 continuously or periodically. If it is determined that it is within the radio base station range (Yes in step 601), the CPU 201 receives the position ID information using the position information acquisition function 203 (step 602). In step 603, the CPU 201 refers to the memory 205 and determines whether or not the received position ID corresponds to driving area information. If the CPU 201 determines that the wireless terminal 101 is within the sensor driving range, the CPU 201 determines in step 604 whether or not the wireless terminal 101 is still within the wireless base station range, and if it is determined that the wireless terminal 101 is outside the wireless base station range, step 601. Returning to step S605, if it is determined that the mobile station is still within the radio base station range, the sensor function 204 is driven in step 605. Information obtained by the sensor function 204 is transmitted to the outside via the wireless communication function 202. When step 605 is executed, the CPU 201 returns to step 601. Or you may return to step 601 after driving the sensor function 204 for a fixed period of time continuously or periodically.

一方、ＣＰＵ２０１は、ステップ６０３でセンサ駆動圏内であると判定すると、センサ機能２０４が動作中であれば（ステップ６０６）該センサ機能を停止し（ステップ６０７）ステップ６０１に戻り、動作中でなければステップ６０６から直ちにステップ６０１に戻る。   On the other hand, when the CPU 201 determines in step 603 that the sensor is within the driving range of the sensor, if the sensor function 204 is in operation (step 606), the sensor function is stopped (step 607), and the process returns to step 601. The process returns from step 606 to step 601 immediately.
