Abstract

PROBLEM TO BE SOLVED: To give an alarm that the battery has run out in consideration of the use condition, not only the data on the remaining capacity of the battery in a portable instrument.
SOLUTION: The necessary alarm is that the battery run out, for example, in a day, while such as alarm has little effect to inform the remaining capacity of the battery is 10%. Further, as for a primary battery, giving the alarm in the situation that no primary battery can be obtained, or as for a secondary battery, giving the alarm in the situation that the battery cannot be charged is meaningless; but instead, the timing for giving the alarm should be considered. Therefore, by storing a model of power consumption of the instrument in the instrument and always grasping the current capacity of the battery, the time when the battery runs out is estimated, and if necessary, the alarm is given when the instrument is used under the similar situation.

【発明の詳細な説明】 DETAILED DESCRIPTION OF THE INVENTION

【0001】 [0001]

【発明の属する技術分野】本発明は携帯電話や電子手帳など電池で動作する機器の電池切れ予告の方法に関する。 The present invention relates to relates to a battery power warning of the method of the devices operating on batteries such as mobile phones and electronic organizers.

【0002】 [0002]

【従来の技術】従来、携帯機器の電池切れ警報は、電池の電圧を監視してあるレベルより以下に低下すると電池切れ警報を出すのが一般的である。 Conventionally, battery exhaustion alarm portable devices, put out the battery exhaustion alarm when drops below the level that is monitoring the voltage of the battery is generally used. この警報を出した後も、一定の時間は機器が使用できる。 Even after you put this warning, a certain period of time is the equipment can be used. その時間の長さは警報を出すべき電圧の設定によって変化する。 Length of the time varies depending on the setting of the voltage to the alarm sounds.

【0003】従来行われている第2の方法は電池の消費電力を積算し、電池のもつ電力量と比較して電池切れ警報を出すものである。 [0003] The second method that has been done conventionally by integrating the power consumption of the battery is intended to issue the battery dead alarm as compared to the amount of power possessed by the battery. 2次電池を用いる機器などで、消費電流を検出し電流に比例した周波数のパルスを発生させ、それを積算する事で消費電力量を算出することが行われている。 In such devices using a secondary battery, consumption current generates pulses having a frequency proportional to the detected current, it has been conducted to calculate the power consumption by accumulating it. この方法は前記の方法より精度が高い。 This method has higher accuracy than the method.

【0004】 [0004]

【発明が解決しようとする課題】従来から行われている上記の方法は、基本的に電池の残量を推定して、一定の残量を切ったところで警報を出すという原理に基づいている。 The above method is conventional [0005] is to estimate the remaining amount of the basic cell, based on the principle that alert where cut a certain remaining amount. しかしながら機器の使用者の立場からすれば電池の残量でなく、実際に使用できる時間がある値を切った時点で警報を出して欲しいのである。 However, instead of the remaining capacity of the battery if from the point of view of the user of the equipment, it is want you to issue a warning at the time of cut there is a time that can be actually used value.

【0005】たとえばあと1日で電池が切れるという警報が欲しいのであって、電池の残量が10%であるというような警報は実地の効果が少ない。 [0005] For example, there is the want the alarm that the battery runs out in one day later, alarm, such as that the remaining amount of the battery is 10% has less effect of the field. さらに1次電池の場合なら電池が手に入らない状況での警報であるとか、 In addition Toka battery if the case of the primary battery is a warning in situations that do not fall into the hands,
2次電池の場合なら充電できない状況での警報は意味がないのであって、警報を出すタイミングも問題である。 The alarm in a situation that can not be charged if the case of the secondary battery be than no sense, is a timing problem that alert.

【0006】しかし電池の持続時間は機器の使用状況に依存する事はいうをまたず、従って上記の要求に答えるには機器の使用状況を知る必要がある。 [0006] However, the duration of the battery without waiting for the say that depends on the usage of the equipment, and therefore the answer to the above requirements, it is necessary to know the usage of the equipment.

【0007】 [0007]

【課題を解決するための手段】本発明においては上記の課題を解決するために、機器の電力消費モデルを機器内部に保持する。 In the present invention SUMMARY OF] In order to solve the above problems, to hold the power consumption model of the device to the internal device. すなわち機器の消費電力は使用状況に依存するので、ある時点以降の消費電力の予測は機器の使用状態の予測に基づく必要がある。 That is, the power consumption of the device is dependent on the usage, the prediction of power consumption since a point in time should be based on the prediction of the use state of the apparatus. 使用状況の予測の簡単な方法は時間と曜日に依るものである。 A simple way of predicting usage is due to the time and day of the week. さらに休日などの情報を含むカレンダ機能を利用すればよい。 Furthermore, it is sufficient to use the calendar function that contains information such as the holiday. ビジネス用の携帯電話では週日の昼間が使用量が多いであろう。 A mobile phone for business would be there are many usage during the day on weekdays.

【0008】本発明ではかかる時間、曜日などをパラメータにとった消費電力モデルを機器内部の情報として蓄積する。 [0008] The time required in the present invention, stores the power consumption model took day and the parameter as information inside the device. このモデルは簡単には固定のものでもよいが、 This model may also easy to those of fixed but,
実使用状況のデータに基づき適応的に変化・学習させることもできる。 It may be adaptively changing and learning based on the data of the actual usage. 警報のタイミングの計算には消費電力量の予測のほかに電池の総容量の推定が必要である。 The calculation of the timing of the alarm requires the estimation of the total capacity of the battery in addition to the prediction of the consumed electric power amount. 簡単には電池の仕様値を用いる事もできるが、2次電池では充電を重ねるごとに総容量が減少するので、これも実使用データに基づき適応的に推定量を変化させることができる。 Briefly can also be used specification value of the battery, but the secondary battery because the total volume is reduced to each successive charging, which also can be changed adaptively estimates based on actual usage data.

【0009】また、警報を出すタイミングも例えば朝の出勤前に警報が出ても困るのであって、前夜の余裕ある時に出て欲しいものである。 [0009] In addition, there is troubled even out an alarm before timing also for example in the morning attendance to issue a warning, is what you want out when there is the eve of the room. これは予め都合よいタイミングを入力して指定すればよい。 This may be specified by entering the pre-convenient timing.

【0010】最近の携帯情報機器は概ねマイクロコンピュータを内蔵しており上記のような消費電力モデルや、 [0010] and the latest mobile information equipment is generally the power consumption models, such as has a built-in micro-computer,
電池容量モデルを計算する事は容易である。 It is easy to calculate the battery capacity model.

【0011】 [0011]

【発明の実施の形態】以下、本発明に従う携帯機器の電池切れ報知方法の実施形態について説明する。 BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments will be described battery exhaustion notification method for a portable device according to the present invention.

【0012】(実施形態1)図1は本発明に係る携帯機器の電池切れ報知方法の実施例を説明する図である。 [0012] (Embodiment 1) FIG. 1 is a diagram for explaining an embodiment of a battery exhaustion notification method for a portable device according to the present invention. 図において10は電池であり給電線12,13を通じて負荷11に電力が供給されている。 10 power is being supplied to the load 11 through and the feed line 12, 13 a battery in FIG. 負荷11は携帯機器全体の電力消費を表わしており、機器の使用状況により消費電力が変化する。 Load 11 represents the power consumption of the entire portable device, the power consumption is changed depending on usage of the device.

【0013】給電線12を流れる電流、給電線12,1 [0013] The current flowing through the feed line 12, the feed line 12, 1
3の間の電圧は計算手段14に伝えられ負荷の消費電力が計算される。 Voltage between the 3 power consumption transmitted to calculation means 14 load is calculated. その電力は計算手段15に伝えられ、時計、 Its power is transmitted to the calculation means 15, watch,
カレンダー17からの情報と合わせて電力の時間経過が記録される。 Together with information from the calendar 17 time lapse of power is recorded. カレンダーは曜日や休日などの情報を持っているから計算手段には時間別変動、曜日変動、休日と週日の差異などのデータが蓄積されていく。 Calendar another change time in the calculation means because they have the information, such as day of the week and holidays, day of the week fluctuations, data such as the difference between the holidays and weekdays are accumulated. その方法は初期に標準的な時間変動モデルを与えておき、機器を実使用するにしたがって、実データでモデルを修正する方法をとる。 The method initially advance fed a standard time-varying model, according to actual use equipment, employ a method of modifying the model in real data.

【0014】一方、電池10の総容量は一次電池であればその規格値から、2次電池であれば放電データから計算手段16によりモデル的に計算できる。 [0014] On the other hand, the total capacity of the battery 10 from its standard value when a primary battery, a calculation unit 16 from the discharge data if secondary battery can model to calculate. 二次電池は充放電を繰り返すと総容量が減少していき、例えば500回サイクルのあとは約70%の容量になるが、本発明では満充電から放電終了までの電気量が毎回、データとして得られるので、電池の劣化があっても、残量の計算に大きな誤差を生じることはない。 Rechargeable battery repeats charging and discharging as the total capacity gradually decreases, for example after 500 cycles is a volume of about 70%, quantity of electricity in the present invention from the fully charged until the end of discharge every time, as the data since the resulting, even when deterioration of the battery, does not cause large errors in the calculation of the remaining amount.

【0015】なお電池の残量は放電した積算電流によるのが一般的であるから、上記の計算において、総電力の計算を総電流の計算で置き換える事もできる。 [0015] Note that since the battery level it is common due to the discharged cumulative current, in the above calculation, it is also possible to replace the total power calculation in the calculation of the total current.

【0016】電池の残量情報は電池の総容量から充電後または交換後の総電力消費量を差し引いて求められ計算手段15に蓄えられる。 The remaining amount information of the battery is stored in a calculating unit 15 is calculated by subtracting the total power consumption amount after the charging or after replacement of the total capacity of the battery. このようにして電池の容量、充電後の総放電量が求められるのでこれを用いて適当なタイミングで電池切れ警報を出す事ができる。 Battery capacity in this way, this because the total amount of discharge after charging is required can issue a battery exhaustion alarm at appropriate timing using.

【0017】電池切れ警報の出し方は、例えば電池切れの24時間前など、設定された時間の長さに到達したら警報を出すのが一つの方法である。 [0017] How to put out of battery exhaustion alarm, such as, for example, 24 hours before the battery exhaustion, has put out an alarm when it reaches the length of time that has been set is one way. しかし他の方法は使用者の生活サイクルに合わせる方法であり、例えば帰宅時間以前に電池切れが予測されるときは、自宅を出る前に警報を出す、前の晩に警報を出すなどの方法を取る事もできる。 However, other method is a method to match the life cycle of the user, for example, when the battery power is expected to return home time before, alert before leaving the home, a method such as issuing a warning the night before it is also possible to take. これは警報タイミング計算手段18によってなされる。 This is done by the warning timing calculator 18.

【0018】警報タイミング計算手段18には警報を出すべきタイミングに関する入力手段を備えている。 [0018] The warning timing calculating means 18 and an input unit on when to alert. それにより警報を出すべき時刻、警報から電池切れまでの時間などを外部から設定する事が可能である。 Whereby the time to issue a warning, it is possible to set up such as the time until the battery out from the outside from the alarm.

【0019】表示装置19は携帯電話の表示装置と兼用のものである。 [0019] The display device 19 is of a shared with the mobile phone of the display device. また表示と併用してバイブレータや音響などを使うことが出来る。 Also it can be used such as a vibrator and sound in conjunction with the display.

【0020】 [0020]

【発明の効果】以上説明したように本発明によれば、機器の電力消費モデルを機器内部に保持し、また電池の容量を常に把握する事によって、同じような使用状況で経過した場合、電池切れが起こる時間を推定し、必要により警報を出す事ができる。 According to the present invention as described in the foregoing, if the holding power consumption model of the device to the internal device, also by always grasp the capacity of the battery, it has passed in similar usage, battery to estimate the time that cut occurs, it is possible to issue a warning if necessary. これは単なる電池の残量からする警報と相違して、使用状況における電池切れの予測によるものであるから、より実用に近い警報を出すことが出来る。 This differs from the alarm to the remaining amount of mere battery, since it is due to predictive battery exhaustion in usage, can alert closer to practical use. また電力消費モデルに時刻依存性、曜日依存性などの情報を利用し、より正確な警報を出す事が出来る。 The time dependence on the power consumption model, using information such as day of the week-dependent, it is possible to give a more accurate warning.

【0021】これにより不意の電池切れにより携帯機器が使用不能になる不便を大きく回避する事が出来る。 [0021] In this way it is possible to avoid increasing the inconvenience the portable device unusable by the battery out of the unexpected.
