　本発明は、電力シミュレーション装置、および電力シミュレーション方法に関する。本願は、２０１８年１月５日に日本に出願された、特願２０１８－０００５６９号と特願２０１８－０００５７０号と特願２０１８－０００５７１号に基づき優先権を主張し、その内容をここに援用する。 The present invention relates to a power simulation apparatus and a power simulation method. Priority is claimed on Japanese Patent Application Nos. 2018-000569, 2018-000570, and 2018-000571 filed on Jan. 5, 2018, the content of which is incorporated herein by reference. Do.
　近年、電子回路や無線技術の低消費電力化により、周囲の環境から電気エネルギーを得ることで、配線や電池交換なしで動作するワイヤレスセンサといったエネルギーハーベスティング（環境発電）デバイスが注目されている。このようなデバイスでは、例えば太陽電池を用いて発電し、発電したエネルギーを蓄電池に蓄電して制御回路や無線通信回路等を有する電子機器を動作させる。太陽電池等によって得られる電力は環境に依存するものの、例えばμＷ～ｍＷオーダーの微弱な電力である場合が多い。このため、動作させたい電子機器を安定的に連続して動作させるためには、設計段階で発電電力、蓄電電力を含む電子機器の消費電力のバランスを考慮することが重要視されている。 BACKGROUND In recent years, energy harvesting (environmental power generation) devices such as wireless sensors that operate without wiring and battery replacement have attracted attention by obtaining electric energy from the surrounding environment by reducing power consumption of electronic circuits and wireless technologies. In such a device, power is generated using, for example, a solar cell, and the generated energy is stored in a storage battery to operate an electronic device having a control circuit, a wireless communication circuit, and the like. Although the power obtained by the solar cell or the like depends on the environment, it is often a weak power of, for example, the order of μW to mW. Therefore, in order to stably and continuously operate the electronic device to be operated, it is considered important to consider the balance of the power consumption of the electronic device including the generated power and the stored power at the design stage.
　このため、太陽電池の発電電力を電子機器の消費電力を比較する手法や、発電された電力をＤＣＤＣ（直流－直流）変換器で変換する際の変換効率を考慮した消費電力を考慮することが検討されている。
　例えば、特許文献１には、太陽電池発電システムの発電量を演算するシミュレータが開示されている。 For this reason, it is necessary to consider the power consumption considering the conversion efficiency at the time of converting the generated power of the solar battery by the DCDC (direct current-direct current) converter and comparing the power consumption of the electronic device. It is being considered.
For example, Patent Document 1 discloses a simulator that calculates the amount of power generation of a solar cell power generation system.

　図３４に示す例では、１日あたり供給可能な電力量が平均値の際、電子機器２５Ａに電力を供給できる期間（駆動可能な期間）は、運用開始からの時間が、約２０時間～約６８時間の期間、約９１時間～約１４０時間の期間、約１６３時間～である。また、１日あたり供給可能な電力量が平均値の際、電子機器２５Ａに電力を供給できない期間（駆動できない期間）は、運用開始からの時間が、０時～約２０時間の期間、約６８時間～約９１時間の期間、約１４０時間～約１６３時間の期間である。 In the example shown in FIG. 34, when the amount of power that can be supplied per day is an average value, the period in which power can be supplied to the electronic device 25A (the drivable period) is about 20 hours to about A period of 68 hours, a period of about 91 hours to about 140 hours, and a period of about 163 hours. In addition, when the amount of power that can be supplied per day is an average value, the period when power can not be supplied to the electronic device 25A (period when it can not be driven) is about 68 hours from 0 o'clock to about 20 hours from the start of operation. The period of time is about 91 hours, and the period of about 140 hours to about 163 hours.
　また、図３４に示すように、１日あたり供給可能な電力量が最小値の際、電子機器２５Ａに電力を供給できる期間（駆動可能な期間）は、運用開始からの時間が、約２９時間～約６３時間の期間、約９７時間～約１２７時間の期間、約１６２時間～である。また、１日あたり供給可能な電力量が最小値の際、電子機器２５Ａに電力を供給できない期間は、運用開始からの時間が、０時～約２９時間の期間、約６３時間～約９７時間の期間、約１２７時間～約１６２時間の期間である。１日あたり供給可能な電力量が平均値に比べて最小時の際、電子機器２５Ａに電力を供給できない期間が長くなり、電子機器２５Ａに電力を供給できる期間が短くなることを、利用者は、蓄電池２３Ａの電圧対時間の変化を示すグラフの画像ｇ１１３Ａを見て確認することができる。 In addition, as shown in FIG. 34, when the amount of power that can be supplied per day is the minimum value, the period in which power can be supplied to the electronic device 25A (the drivable period) is approximately 29 hours from the start of operation. A period of ~ 63 hours, a period of about 97 hours to about 127 hours, ~ 162 hours. In addition, when the amount of power that can be supplied per day is the minimum value, the period from the start of operation is about 63 hours to about 97 hours, from 0 o'clock to about 29 hours, during the period when electric power can not be supplied Period of about 127 hours to about 162 hours. When the amount of power that can be supplied per day is at a minimum compared to the average value, the user can not supply power to the electronic device 25A longer, and the user can reduce the period that can supply power to the electronic device 25A. The image g113A of the graph showing the change of the voltage of the storage battery 23A versus time can be confirmed.

The change in voltage of the storage battery is calculated, and the display unit 14A graphs the change in voltage of the storage battery with respect to the elapsed time. Further, in the image with the code g113Ag in FIG. 34, the display unit 14A graphs the change of the illuminance with respect to the elapsed time based on the illuminance and the irradiation time with which the solar cell 21A set by the setting unit 11A is irradiated. It is the result of displaying the change of the voltage of the storage battery with respect to elapsed time on the graph superimposed.
　また、図３４の符号ｇ１１３Ａｅ、ｇ１１３Ａｆの画像は、演算部１２Ａが、求めた時間変化に対する前記蓄電池の電圧の変化に基づいて、電子機器２５Ａ（負荷回路）を駆動可能な期間および前記負荷回路を駆動できない期間のうち少なくとも１つを求め、表示部１４Ａが、演算部１２Ａが求めた電子機器２５Ａを駆動可能な期間および電子機器２５Ａを駆動できない期間のうち少なくとも１つを、グラフ化した蓄電池２３Ａの電圧の変化のグラフに対応付けて、重ねて表示した結果である。 In addition, the images with reference numerals g113Ae and g113Af in FIG. 34 have periods during which the operation unit 12A can drive the electronic device 25A (load circuit) and the load circuit based on the change in the voltage of the storage battery with respect to the time change obtained. The storage battery 23A is a graph of at least one of the periods in which the display unit 14A can drive the electronic device 25A and the periods in which the display device 14A can not drive the electronic device 25A. It is the result of being displayed in association with the graph of the change in voltage of.
　ここで、図３４において、ポインタ画像ｇ３０１Ａを用いた設定方法の例を説明する。
　なお、利用者は、設定部１１Ａを操作することで、ポインタ画像ｇ３０１Ａを操作する指示を行う。
　図３４において、例えば、太陽電池２１Ａに照射される照度を変更したいとき、ポインタ画像ｇ３０１Ａを操作して、符号ｇ１１３Ａｇの画像を高さ方向に変更するように操作する。演算部１２Ａは、操作された結果を検出し、符号ｇ１１３Ａｇの画像において、例えば、照度を５００［ｌｕｘ］から７００［ｌｕｘ］に変更する。これに伴い、表示部１４Ａは、センサシステム２Ａが設置される環境の光の状態の設定画像ｇ１０２Ａ（図２２、図２３）において、照度を５００［ｌｕｘ］から７００［ｌｕｘ］に変更する。
　さらに、表示部１４Ａは、時間変化に対する前記蓄電池の電圧の変化、電子機器２５Ａ（負荷回路）を駆動可能な期間、前記負荷回路を駆動できない期間を再演算して、蓄電池２３Ａの電圧対時間の変化を示すグラフの画像ｇ１１３Ａを更新する。 Here, in FIG. 34, an example of a setting method using the pointer image g301A will be described.
The user operates the setting unit 11A to issue an instruction to operate the pointer image g301A.
In FIG. 34, for example, when it is desired to change the illuminance irradiated to the solar cell 21A, the pointer image g301A is operated to operate to change the image of the code g113Ag in the height direction. The operation unit 12A detects the operated result, and changes the illuminance, for example, from 500 [lux] to 700 [lux] in the image of g113 Ag. Along with this, the display unit 14A changes the illuminance from 500 [lux] to 700 [lux] in the setting image g102A (FIGS. 22 and 23) of the state of light in the environment where the sensor system 2A is installed.
Furthermore, the display unit 14A recalculates a change in voltage of the storage battery with respect to time change, a period in which the electronic device 25A (load circuit) can be driven, and a period in which the load circuit can not be driven. The graph image g113A indicating the change is updated.
　図３４において、ポインタ画像ｇ３０１Ａを操作して変更可能な項目は、例えば、太陽電池２１Ａに照射される照度、太陽電池２１Ａに照射される光照射時間、蓄電池２３Ａに蓄電された電力を再出力する電圧値、充電上限電圧、放電下限電圧、電子機器２５Ａ（負荷回路）を駆動可能な期間、前記負荷回路を駆動できない期間である。
　例えば、電子機器２５Ａ（負荷回路）を駆動可能な期間がポインタ画像ｇ３０１Ａの操作によって変更された場合、演算部１２Ａは、図３４のグラフを求めた逆演算を行って、例えば、照度、光照射時間、太陽電池の発電効率、動作時間、動作インターバルに対して予め設定された優先順位に基づいて、設定値を変更して図２２や図２３の各表示画像を変更する。なお、照度、光照射時間、太陽電池の発電効率、動作時間、動作インターバルの優先順位は、予め利用者が設定部１１Ａを操作して設定を行い、設定された結果を演算部１２Ａが記憶部１３Ａに記憶させる。 In FIG. 34, items that can be changed by operating the pointer image g301A are, for example, the light intensity irradiated to the solar cell 21A, the light irradiation time irradiated to the solar cell 21A, and the power stored in the storage battery 23A again A voltage value, a charge upper limit voltage, a discharge lower limit voltage, a period in which the electronic device 25A (load circuit) can be driven, and a period in which the load circuit can not be driven.
For example, when the period during which the electronic device 25A (load circuit) can be driven is changed by the operation of the pointer image g301A, the operation unit 12A performs the reverse operation of obtaining the graph of FIG. The set value is changed based on the time, the power generation efficiency of the solar cell, the operation time, and the priority set in advance with respect to the operation interval, and the display images of FIG. 22 and FIG. 23 are changed. The user operates the setting unit 11A in advance to set the illuminance, the light irradiation time, the power generation efficiency of the solar cell, the operation time, and the priority of the operation interval, and the calculation unit 12A stores the set result. Make it memorize in 13A.
　図３５は、照度と蓄電池２３Ａの電圧の時間変化の例を示す図である。図３５において、横軸は時間、左縦軸は蓄電池２３Ａの電圧、右縦軸は照度である。
　図３５に示す例では、０時～２０時の期間、Ｌ１（例えば５００［ｌｕｘ］）の照度が太陽電池２１Ａに照射され、蓄電池２３Ａの電圧がＶ１となる。そして、消灯時の２０時～２４時の期間、Ｌ２（例えば０［ｌｕｘ］）の照度が太陽電池２１Ａに照射され、蓄電池２３Ａの電圧がＶ２となる。また、本実施形態では、１日（２４時間）を単位時間とする。 FIG. 35 is a diagram showing an example of the time change of the illuminance and the voltage of the storage battery 23A. In FIG. 35, the horizontal axis is time, the left vertical axis is the voltage of storage battery 23A, and the right vertical axis is illuminance.
In the example shown in FIG. 35, the illuminance of L1 (for example, 500 [lux]) is irradiated to the solar cell 21A in the period from 0 o'clock to 20 o'clock, and the voltage of the storage battery 23A becomes V1. Then, the illuminance of L2 (for example, 0 [lux]) is irradiated to the solar cell 21A in the period from 20 o'clock to 24 o'clock when the light is turned off, and the voltage of the storage battery 23A becomes V2. In the present embodiment, one day (24 hours) is taken as a unit time.
　図３６は、発電量と消費電力のエネルギー収支を表す画像ｇ１１４Ａの例を示す図である。図３６において、縦軸は、発電された発電電力量に対する総消費エネルギーの比である。符号ｇ１１４Ａａは、単位時間あたり供給可能な電力量が平均値の場合のエネルギー収支を表す。符号ｇ１１４Ａｂは、単位時間あたり供給可能な電力量が最小値の場合のエネルギー収支を表す。鎖線ｇ１１４Ａｃは、発電された発電電力量に対する総消費エネルギーの比が１００％、すなわちバランスが取れているラインを表す。 FIG. 36 is a diagram illustrating an example of an image g114A representing an energy balance of the power generation amount and the power consumption. In FIG. 36, the vertical axis is the ratio of the total energy consumption to the generated power generation amount. The code g114Aa represents the energy balance when the amount of power that can be supplied per unit time is an average value. The code g114Ab represents the energy balance when the amount of power that can be supplied per unit time is the minimum value. The dashed-dotted line g114Ac represents a line in which the ratio of the total energy consumption to the generated power generation amount is 100%, that is, a balanced line.
　図３６に示す例では、単位時間あたり供給可能な電力量が平均値の場合のエネルギー収支が６９．５％であり、単位時間あたり供給可能な電力量が最小値の場合のエネルギー収支が４８．６％である。利用者は、このようなエネルギー収支を確認して、例えば太陽電池２１Ａの数量を増やしたり、太陽電池２１Ａを選択し直したり等、設定をやり直して、エネルギー収支のバランスが取れる設定を検討することができる。 In the example shown in FIG. 36, the energy balance when the amount of power that can be supplied per unit time is an average value is 69.5%, and the energy balance when the amount of power that can be supplied per unit time is a minimum value is 48. 6%. The user confirms such an energy balance, for example, increases the number of solar cells 21A, reselects the solar cells 21A, etc., and considers setting that balances the energy balance by re-setting. Can.
　図３７は、一次電池２４Ａのバッテリ寿命を示す画像ｇ２１１Ａの例を示す図である。図３７に示すように、一次電池２４Ａのバッテリ寿命を示す画像ｇ２１１Ａには、１日あたり供給可能な電力量が平均値の場合の一次電池２４Ａのバッテリ寿命［ｙｅａｒｓ］（ｔｙｐ）、単位時間あたり供給可能な電力量が最小値の場合の一次電池２４のバッテリ寿命［ｙｅａｒｓ］（ｍｉｎ）が含まれる。図３７に示す例では、１日あたり供給可能な電力量が平均値の場合の一次電池２４Ａのバッテリ寿命が３．７［ｙｅａｒｓ（年）］（ｔｙｐ）であり、１日あたり供給可能な電力量が最小値の場合の一次電池２４Ａのバッテリ寿命が２．２［ｙｅａｒｓ］（ｍｉｎ）である。 FIG. 37 is a view showing an example of an image g211A showing the battery life of the primary battery 24A. As shown in FIG. 37, in the image g211A showing the battery life of the primary battery 24A, the battery life [years] (typ) of the primary battery 24A when the amount of power that can be supplied per day is an average value, per unit time The battery life [years] (min) of the primary battery 24 when the amount of power that can be supplied is the minimum value is included. In the example shown in FIG. 37, the battery life of the primary battery 24A is 3.7 [years (year)] (typ) when the amount of power that can be supplied per day is an average value, and the power that can be supplied per day is typical. The battery life of the primary battery 24A when the amount is the minimum value is 2.2 [years] (min).
　なお、上述した例では、太陽電池の選択画像ｇ１０４Ａ、電子機器の動作状態や消費電力の表示画像ｇ１０８Ａ、蓄電池の電圧対時間の変化を示すグラフの画像ｇ１１３Ａに対して、ポインタ画像ｇ３０１Ａを操作して、設定値等を変更する例を説明したが、これに限らない。図２２、図２３において表形式で示した設定項目を、ポインタ画像ｇ３０１Ａを操作して、設定値等を変更するようにしてもよい。 In the example described above, the pointer image g301A is manipulated with respect to the selected image g104A of the solar cell, the display image g108A of the operation state of the electronic device and the power consumption, and the graph g113A showing the change of voltage versus time of the storage battery. Although the example of changing the setting value etc. has been described, the present invention is not limited to this. The setting items etc. may be changed by operating the pointer image g301A for the setting items shown in tabular form in FIG. 22 and FIG.
　例えば、センサシステム２Ａが設置される環境の光の状態の設定画像ｇ１０２Ａにおいて、ポインタ画像ｇ３０１Ａで照度が選択された場合、表示部１４Ａは、選択可能な照度（例えば、１００、２００、３０、・・・、１００００）を、図２２や図２３の画像の上のレイヤに、例えばスライダ形式やポップアップメニュー形式で表示させるようにしてもよい。利用者は、表示されたポインタ画像ｇ３０１Ａを操作して、スライダを操作することで、例えば照度を変更するように指示してもよい。また、利用者は、ポインタ画像ｇ３０１Ａを操作して、電源回路２２Ａの昇圧効率、降圧効率、静止電流、出力電圧、蓄電池２３Ａの容量、蓄電池２３Ａの自己放電電流等を変更するようにしてもよい。 For example, in the setting image g102A of the light state of the environment in which the sensor system 2A is installed, when the illuminance is selected in the pointer image g301A, the display unit 14A can select selectable illuminance (for example, 100, 200, 30,. .., 10000) may be displayed in a layer above the image of FIG. 22 or 23, for example, in the form of a slider or a pop-up menu. The user may operate the displayed pointer image g301A to operate the slider, for example, to instruct to change the illuminance. In addition, the user may operate the pointer image g301A to change the boosting efficiency, step-down efficiency, quiescent current, output voltage, capacity of storage battery 23A, self-discharge current of storage battery 23A, etc. of power supply circuit 22A. .
　また、上述した例では、図２２や図２３の画像に対して、ポインタ画像ｇ３０１Ａを操作して設定を変更する例を説明したが、これに限らない。例えば、演算部１２Ａが初期状態の設定値の画像（例えば図２２）のデータを記憶部１３Ａから読み出し、表示部１４Ａがこの初期状態の設定に基づいて図２２の画像を表示するようにしてもよい。そして、利用者は、この初期状態の画面を変更するようにポインタ画像ｇ３０１Ａを操作するようにしてもよい。あるいは、演算部１２Ａは、設定を全て初期化し、表示部１４Ａは、図２２の設定値を空欄の状態で表示させるようにしてもよい。そして、利用者は、この初期状態の画面において、各項目の設定値をポインタ画像ｇ３０１Ａを操作して選択して設定するようにしてもよい。 Moreover, although the example which operates the pointer image g301A and changes a setting with respect to the image of FIG.22 and FIG.23 was demonstrated in the example mentioned above, it does not restrict to this. For example, even if the calculation unit 12A reads data of an image (for example, FIG. 22) of the setting value in the initial state from the storage unit 13A and the display unit 14A displays the image in FIG. Good. Then, the user may operate the pointer image g301A to change the screen in this initial state. Alternatively, the calculation unit 12A may initialize all the settings, and the display unit 14A may display the setting values in FIG. 22 in blanks. Then, on the screen in this initial state, the user may select and set the setting value of each item by operating the pointer image g301A.

　次に、演算部１２Ａ、表示部１４Ａが行う処理手順例を説明する。
　図３８は、本実施形態に係る演算部１２Ａ、表示部１４Ａが行う処理手順例を示すフローチャートである。 <Example of procedure of simulation>
Next, an example of a processing procedure performed by the calculation unit 12A and the display unit 14A will be described.
FIG. 38 is a flowchart showing an example of the processing procedure performed by the calculation unit 12A and the display unit 14A according to this embodiment.
　（ステップＳ１０１）演算部１２Ａは、利用者が設定部１１Ａを操作して設定、選択した設定情報を取得する。なお、設定部１１Ａが操作された結果は、キーボード等によって設定された操作結果、ポインタ画像ｇ３０１Ａ（図２２等）によって選択や変更された操作結果のいずれかである。 (Step S101) The calculation unit 12A acquires setting information selected and set by the user operating the setting unit 11A. The result of the operation of the setting unit 11A is any of the operation result set by a keyboard or the like, and the operation result selected or changed by the pointer image g301A (FIG. 22 or the like).
　（ステップＳ１０２）演算部１２Ａは、取得した設定情報に応じたパラメータを、記憶部１３Ａから読み出す。続けて、演算部１２Ａは、記憶部１３Ａからシミュレーションに使用する数式を読み出す。 (Step S102) Operation unit 12A reads from storage unit 13A a parameter corresponding to the acquired setting information. Subsequently, the calculation unit 12A reads a mathematical expression used for simulation from the storage unit 13A.

Further, the dashed-dotted line g113Bb represents the discharge lower limit voltage (lower limit voltage). The dashed-dotted line g113Bc represents a voltage value for re-outputting the power stored in the storage battery 23B. That is, when the voltage value of storage battery 23B reaches 3.3 (V) shown by a dashed-dotted line g113Bc, the discharge of the power of storage battery 23B is started. The dashed-dotted line g113Bd represents the charging upper limit voltage. A region indicated by reference sign g113Be represents a period in which power can not be supplied to the electronic device 25B.
