　（制御システム１００）
　図１は、実施の形態における制御システム１００を備えた装置２００の回路図である。制御システム１００の構成について説明する。制御システム１００は、電源部１と、負荷部２と、発電部３と、制御部２０とを有する。電源部１は電力Ｐ１を出力する。負荷部２は電力Ｐ１によって駆動される。発電部３は、電力Ｐ３を外力によって発電する。制御部２０は、電力Ｐ３が出力されたことにより、負荷部２へ電力Ｐ１を供給する。 (Control system 100)
FIG. 1 is a circuit diagram of an apparatus 200 including a control system 100 according to an embodiment. The configuration of the control system 100 will be described. The control system 100 includes a power supply unit 1, a load unit 2, a power generation unit 3, and a control unit 20. The power supply unit 1 outputs electric power P1. The load unit 2 is driven by electric power P1. The power generation unit 3 generates power P3 with external force. The controller 20 supplies the power P1 to the load unit 2 when the power P3 is output.
　次に、制御システム１００の動作について説明する。発電部３は、外力を受けた場合にその外力を電力Ｐ３に変換することで電力Ｐ３を発電して出力する。制御部２０は、電力Ｐ３が出力されたことを検出する。電力Ｐ３が出力されたことを検出すると、制御部２０は、電源部１から負荷部２へ電力Ｐ１を出力する。負荷部２は、電源部１から電力Ｐ１を供給されて駆動され始める。 Next, the operation of the control system 100 will be described. When receiving the external force, the power generation unit 3 converts the external force into the power P3 to generate and output the power P3. The control unit 20 detects that the power P3 is output. When detecting that the power P3 is output, the control unit 20 outputs the power P1 from the power supply unit 1 to the load unit 2. The load unit 2 is supplied with electric power P1 from the power supply unit 1 and starts to be driven.
　前述の従来の制御システムでは、制御部が負荷部の駆動を制御している。したがって、従来の制御システムが駆動されている間、電源部から制御部や負荷部へ電力を常時供給しなければならない。したがって、従来の制御システムの消費電力は大きくなってしまう。 In the above-described conventional control system, the control unit controls the driving of the load unit. Therefore, power must be constantly supplied from the power supply unit to the control unit and the load unit while the conventional control system is driven. Therefore, the power consumption of the conventional control system becomes large.
　実施の形態における制御システム１００では、発電部３は、負荷部２を駆動するためのスイッチとして機能している。そのため、制御システム１００は、電源部１からの電力Ｐ１を負荷部２へ常時は供給しなくてよい。よって、制御システム１００は、消費電力を抑制できる。 In the control system 100 in the embodiment, the power generation unit 3 functions as a switch for driving the load unit 2. Therefore, the control system 100 does not always have to supply the power P1 from the power supply unit 1 to the load unit 2. Therefore, the control system 100 can suppress power consumption.
　図２は制御システム１００のブロック図である。以下、説明の理解を助けるために「電気的に接続」や「信号」という表現を用いる。 FIG. 2 is a block diagram of the control system 100. Hereinafter, the expressions “electrically connected” and “signal” are used to help understand the description.
　「電気的に接続」とは、電気信号をやりとりできるように繋がっていることを意味している。つまり、「電気的に接続」されている構成とは、たとえば、導線によって複数の電子部品が繋がっていている構成や、トランスによって誘導電流を発生させて電気信号のやりとりを行う構成や、絶縁コンバータなどを介して電気信号をやりとりする構成などを含む。 “Electrically connected” means connected so that electrical signals can be exchanged. In other words, “electrically connected” configurations include, for example, a configuration in which a plurality of electronic components are connected by a conducting wire, a configuration in which an electrical current is exchanged by generating an induced current using a transformer, an insulating converter The structure etc. which exchange an electric signal through these etc. are included.
　また、電気信号などの表現で用いる「信号」とは、電流や電圧が変化する電力や、電流や電圧が一定の電力、電流や電圧の向きが変化する電力や、電流や電圧の向きが一定の電力のことである。つまり、「信号」は、たとえば、情報や指示などの送受信等に用いる信号や、電子部品を駆動するための電力を含む。 In addition, “signal” used in expressions such as electrical signals is power that changes current and voltage, power that has a constant current and voltage, power that changes the direction of current and voltage, and constant direction of current and voltage. It is the electric power of. That is, the “signal” includes, for example, a signal used for transmission / reception of information and instructions, and electric power for driving an electronic component.
　制御システム１００は、電源部１と、負荷部２と、発電部３と、制御部２０と、切替部４とを有する。 The control system 100 includes a power supply unit 1, a load unit 2, a power generation unit 3, a control unit 20, and a switching unit 4.
　発電部３は、発信部１０と、整流出力部４０と、整流平滑出力部５０と、電圧降下部６０と、電圧降下部７０と、フィルタ回路８０１、８０２と、駆動部９０とを有する。制御部２０は、計測端子２１と、電圧計測部２２と、制御素子２４と、電源端子２５と、起動部３０とを有する。 The power generation unit 3 includes a transmission unit 10, a rectification output unit 40, a rectification smoothing output unit 50, a voltage drop unit 60, a voltage drop unit 70, filter circuits 801 and 802, and a drive unit 90. The control unit 20 includes a measurement terminal 21, a voltage measurement unit 22, a control element 24, a power supply terminal 25, and an activation unit 30.
　計測端子２１は、電圧計測部２２と電気的に接続されている。電圧計測部２２は、たとえばアナログ／デジタル変換器である。制御素子２４は、たとえばマイクロコントロールユニット（ＭＣＵ）やセントラルプロセシングユニット（ＣＰＵ）を含む。電源端子２５は、電源と電気的に接続されている。電源は、たとえば一次電池や二次電池や発電体などである。そして、制御部２０は、電源端子２５から制御部２０を駆動するための駆動電力を供給される。 The measurement terminal 21 is electrically connected to the voltage measurement unit 22. The voltage measuring unit 22 is, for example, an analog / digital converter. The control element 24 includes, for example, a micro control unit (MCU) and a central processing unit (CPU). The power terminal 25 is electrically connected to a power source. The power source is, for example, a primary battery, a secondary battery, or a power generator. The control unit 20 is supplied with driving power for driving the control unit 20 from the power supply terminal 25.
　起動部３０は、端子３１、３２を有する。端子３１は、発信部１０と電気的に接続されている。端子３２は、発信部１０と電気的に接続されている。発信部１０から端子３１までの回路と発信部１０から端子３２までの回路とは、たとえばインピーダンス、インダクタンス、抵抗値、電気容量値などが異なるように構成されている。そのため、１つの発信部１０に接続されていても、端子３１に印加される電圧Ｖ３１と端子３２に印加される電圧Ｖ３２との間には差を生じさせられる。 The starting unit 30 has terminals 31 and 32. The terminal 31 is electrically connected to the transmitter 10. The terminal 32 is electrically connected to the transmitter 10. The circuit from the transmission unit 10 to the terminal 31 and the circuit from the transmission unit 10 to the terminal 32 are configured so that, for example, impedance, inductance, resistance value, capacitance value, and the like are different. Therefore, even if connected to one transmitter 10, a difference is generated between the voltage V 31 applied to the terminal 31 and the voltage V 32 applied to the terminal 32.
　起動部３０は、端子３１に印加された電圧Ｖ３１と端子３２に印加された電圧Ｖ３２とを比較する。制御部２０は、起動部３０と電気的に接続されている。起動部３０は、端子３１に印加された電圧Ｖ３１が端子３２に印加された電圧Ｖ３２以上である場合に、端子３１に入力された電圧Ｖ３１を制御素子２４へ出力する。起動部３０は、電圧Ｖ３１が電圧Ｖ３２より低い場合に、制御素子２４へ何も出力しない。 The starting unit 30 compares the voltage V31 applied to the terminal 31 with the voltage V32 applied to the terminal 32. The control unit 20 is electrically connected to the activation unit 30. The starting unit 30 outputs the voltage V31 input to the terminal 31 to the control element 24 when the voltage V31 applied to the terminal 31 is equal to or higher than the voltage V32 applied to the terminal 32. The starting unit 30 outputs nothing to the control element 24 when the voltage V31 is lower than the voltage V32.
　なお、制御部２０は、端子３１に印加された電圧Ｖ３１が端子３２に印加された電圧Ｖ３２を上回った場合に端子３１に入力された電圧Ｖ３１を出力してもよい。このように構成することにより制御システム１００の信頼性を向上できる。また、起動部３０は、たとえば制御部２０内に起動部３０としての機能を有しているなどのように制御部２０と一体になっている構成でもよい。 The control unit 20 may output the voltage V31 input to the terminal 31 when the voltage V31 applied to the terminal 31 exceeds the voltage V32 applied to the terminal 32. With this configuration, the reliability of the control system 100 can be improved. In addition, the activation unit 30 may be integrated with the control unit 20 such that, for example, the control unit 20 has a function as the activation unit 30.
　発信部１０は、制御部２０と電気的に接続されている。発信部１０は、たとえば圧電素子、磁気歪素子、コイルと磁石などを有する。そして、発信部１０は、制御システム１００の外から働いた力の強さに応じた交流信号Ｓａｃを出力する。外力は、たとえば振動、衝撃などである。しかし、外力の代わりにエネルギーを用いても良い。エネルギーは、たとえば、熱、磁力などである。 The transmission unit 10 is electrically connected to the control unit 20. The transmitter 10 includes, for example, a piezoelectric element, a magnetostrictive element, a coil and a magnet. Then, the transmitter 10 outputs an AC signal Sac corresponding to the strength of the force that has worked from outside the control system 100. The external force is, for example, vibration or impact. However, energy may be used instead of external force. The energy is, for example, heat, magnetic force or the like.
　整流出力部４０は、端子３１と発信部１０との間で電気的に接続されている。整流出力部４０は整流回路４１を有している。整流回路４１は発信部１０と電気的に接続されており、発信部１０からの交流信号Ｓａｃを脈流である信号Ｓ１に変換する。 The rectification output unit 40 is electrically connected between the terminal 31 and the transmission unit 10. The rectification output unit 40 includes a rectification circuit 41. The rectifier circuit 41 is electrically connected to the transmitter 10 and converts the AC signal Sac from the transmitter 10 into a signal S1 that is a pulsating flow.
　整流回路４１は、ブリッジ接続された複数のダイオードＤ１、Ｄ２、Ｄ３、Ｄ４を有し、ダイオードＤ１～Ｄ４を用いたブリッジ回路で構成されている。 The rectifier circuit 41 includes a plurality of diodes D1, D2, D3, and D4 that are bridge-connected, and includes a bridge circuit that uses the diodes D1 to D4.
　なお、整流回路４１は半波整流回路であっても全波整流回路であってもよい。また、整流回路４１はダイオードＤ１～Ｄ４の代わりにサイリスタやＭＯＳ－ＦＥＴ（Ｍｅｔａｌ－Ｏｘｉｄｅ－Ｓｅｍｉｃｏｎｄｕｃｔｏｒ　Ｆｉｅｌｄ－Ｅｆｆｅｃｔ　Ｔｒａｎｓｉｓｔｏｒ）など他の整流素子を用いてもよい。 The rectifier circuit 41 may be a half-wave rectifier circuit or a full-wave rectifier circuit. The rectifier circuit 41 may use other rectifier elements such as a thyristor or a MOS-FET (Metal-Oxide-Semiconductor Field-Effect Transistor) instead of the diodes D1 to D4.
　整流平滑出力部５０は、端子３２と発信部１０との間で電気的に接続されている。整流平滑出力部５０は、整流回路５１と充電部５２とを有している。整流回路５１は、発信部１０と端子３２との間で電気的に接続されている。整流回路５１は、ブリッジ接続された複数のダイオードＤ３、Ｄ４、Ｄ５、Ｄ６を有してダイオードＤ３～Ｄ６を用いたブリッジ回路で構成されている。整流回路５１は、発信部１０からの交流信号を脈流に変換して充電部５２に向かって出力する。 The rectifying and smoothing output unit 50 is electrically connected between the terminal 32 and the transmission unit 10. The rectifying / smoothing output unit 50 includes a rectifying circuit 51 and a charging unit 52. The rectifier circuit 51 is electrically connected between the transmitter 10 and the terminal 32. The rectifier circuit 51 includes a plurality of diodes D3, D4, D5, and D6 that are bridge-connected, and includes a bridge circuit that uses the diodes D3 to D6. The rectifier circuit 51 converts the AC signal from the transmission unit 10 into a pulsating flow and outputs the pulsating flow toward the charging unit 52.
　なお、整流回路５１は半波整流回路であっても全波整流回路であってもよい。整流回路５１は、ダイオードＤ３～Ｄ６の代わりにサイリスタやＭＯＳ－ＦＥＴ（Ｍｅｔａｌ－Ｏｘｉｄｅ－Ｓｅｍｉｃｏｎｄｕｃｔｏｒ　Ｆｉｅｌｄ－Ｅｆｆｅｃｔ　Ｔｒａｎｓｉｓｔｏｒ）など他の整流素子を用いてもよい。 The rectifier circuit 51 may be a half-wave rectifier circuit or a full-wave rectifier circuit. The rectifier circuit 51 may use other rectifier elements such as a thyristor or a MOS-FET (Metal-Oxide-Semiconductor Field-Effect Transistor) instead of the diodes D3 to D6.
　充電部５２は、整流回路５１と端子３２との間で電気的に接続されている。充電部５２は充電素子５２Ｃを有している。充電素子５２Ｃの一端は、整流回路５１と端子３２との間に電気的に接続している。また、充電素子５２Ｃの他端はグランドに接続されている。充電部５２は、整流回路５１からの脈流を平滑して信号Ｓ２へ変換する。そして、充電部５２は、端子３２に向かって信号Ｓ１を出力する。 The charging unit 52 is electrically connected between the rectifier circuit 51 and the terminal 32. The charging unit 52 has a charging element 52C. One end of the charging element 52 </ b> C is electrically connected between the rectifier circuit 51 and the terminal 32. The other end of the charging element 52C is connected to the ground. Charging unit 52 smoothes the pulsating flow from rectifier circuit 51 and converts it into signal S2. Then, the charging unit 52 outputs a signal S <b> 1 toward the terminal 32.
　たとえばコンデンサを充電素子５２Ｃとして用いることができる。充電素子５２Ｃは、たとえばコイル、トランジスタなどであってもよい。そして、充電素子５２Ｃが、遅延回路として機能するよう接続されている。 For example, a capacitor can be used as the charging element 52C. Charging element 52C may be, for example, a coil or a transistor. The charging element 52C is connected to function as a delay circuit.
　ダイオードＤ３およびダイオードＤ４は、整流回路４１、５１の双方に組み入れられている。言い換えれば、整流回路４１、５１は、ダイオードＤ３およびダイオードＤ４を共有している。整流回路４１、５１が、ダイオードＤ３、Ｄ４を共有することにより回路の小型化を行える。 The diode D3 and the diode D4 are incorporated in both the rectifier circuits 41 and 51. In other words, the rectifier circuits 41 and 51 share the diode D3 and the diode D4. Since the rectifier circuits 41 and 51 share the diodes D3 and D4, the circuit size can be reduced.
　電圧降下部６０は、整流平滑出力部５０と端子３２との間で電気的に接続されている。電圧降下部６０は、抵抗器Ｒ１と抵抗器Ｒ２を有している。抵抗器Ｒ１の一端は、整流平滑出力部５０と電気的に接続されている。抵抗器Ｒ１の他端は接続点６０Ｐで抵抗器Ｒ２の一端と電気的に接続されている。抵抗器Ｒ２の他端は、グランドと電気的に接続されている。電圧降下部６０の接続点６０Ｐは端子３２と電気的に接続されている。すなわち、電圧降下部６０は、電圧降下部６０に入力された信号Ｓ２すなわち充電部５２の電圧ＶＳ２を降下させて得られた電圧を有する信号Ｓ４を端子３２に向かって出力する抵抗分圧回路である。 The voltage drop unit 60 is electrically connected between the rectifying and smoothing output unit 50 and the terminal 32. The voltage drop unit 60 includes a resistor R1 and a resistor R2. One end of the resistor R1 is electrically connected to the rectifying and smoothing output unit 50. The other end of the resistor R1 is electrically connected to one end of the resistor R2 at a connection point 60P. The other end of the resistor R2 is electrically connected to the ground. A connection point 60 </ b> P of the voltage drop unit 60 is electrically connected to the terminal 32. That is, the voltage drop unit 60 is a resistance voltage dividing circuit that outputs the signal S2 input to the voltage drop unit 60, that is, the signal S4 having a voltage obtained by dropping the voltage VS2 of the charging unit 52 toward the terminal 32. is there.
　なお、電圧降下部６０は、２つの抵抗器Ｒ１、Ｒ２を用いて説明したが、抵抗器の数は３つ以上であってもよく、ひとつであってもよい。また、抵抗器Ｒ１、Ｒ２は、固定抵抗器であってもよく可変抵抗器であってもよい。また、電圧降下部６０は、抵抗器Ｒ２の変わりにたとえばコンデンサやコイルなどを用いて構成されていてもよい。 In addition, although the voltage drop part 60 demonstrated using two resistors R1 and R2, the number of resistors may be three or more, and may be one. The resistors R1 and R2 may be fixed resistors or variable resistors. Moreover, the voltage drop part 60 may be comprised using the capacitor | condenser, the coil, etc. instead of the resistor R2.
　電圧降下部７０は、整流出力部４０と端子３１との間で電気的に接続されている。電圧降下部７０は、抵抗器Ｒ３と抵抗器Ｒ４を有している。抵抗器Ｒ３の一端は、整流出力部４０と電気的に接続されている。抵抗器Ｒ３の他端は接続点７０Ｐで抵抗器Ｒ４の一端と電気的に接続されている。抵抗器Ｒ４の他端はグランドと電気的に接続されている。電圧降下部７０の接続点７０Ｐは端子３１と電気的に接続されている。すなわち、電圧降下部７０は、電圧降下部７０に入力された信号Ｓ１の電圧を降下させて得られた電圧を有する信号Ｓ４を端子３１に向かって出力する抵抗分圧回路である。 The voltage drop unit 70 is electrically connected between the rectification output unit 40 and the terminal 31. The voltage drop unit 70 includes a resistor R3 and a resistor R4. One end of the resistor R3 is electrically connected to the rectification output unit 40. The other end of the resistor R3 is electrically connected to one end of the resistor R4 at a connection point 70P. The other end of the resistor R4 is electrically connected to the ground. A connection point 70 </ b> P of the voltage drop unit 70 is electrically connected to the terminal 31. That is, the voltage drop unit 70 is a resistance voltage dividing circuit that outputs a signal S4 having a voltage obtained by dropping the voltage of the signal S1 input to the voltage drop unit 70 toward the terminal 31.
　なお、電圧降下部７０は、２つの抵抗器Ｒ３と抵抗器Ｒ４とを有するが、抵抗器の数は３つ以上であってもよく、ひとつであってもよい。また、抵抗器Ｒ３、Ｒ４は、固定抵抗器であってもよく可変抵抗器であってもよい。また、電圧降下部７０は、抵抗器Ｒ４の変わりにたとえばコンデンサやコイルなどを用いて構成されていてもよい。 The voltage drop unit 70 includes two resistors R3 and R4, but the number of resistors may be three or more, or may be one. Further, the resistors R3 and R4 may be fixed resistors or variable resistors. Moreover, the voltage drop part 70 may be comprised using a capacitor | condenser, a coil, etc. instead of the resistor R4.
　電圧降下部６０と電圧降下部７０との関係について述べる。電圧降下部６０の電圧降下率Ｆ６０は、電圧降下部７０の電圧降下率Ｆ７０よりも大きくなるように構成されている。電圧降下部６０と電圧降下部７０とをこのように構成することにより、起動部３０は、より正確に電圧を比較できる。 The relationship between the voltage drop unit 60 and the voltage drop unit 70 will be described. The voltage drop rate F60 of the voltage drop unit 60 is configured to be larger than the voltage drop rate F70 of the voltage drop unit 70. By configuring the voltage drop unit 60 and the voltage drop unit 70 in this way, the activation unit 30 can compare voltages more accurately.
　実施の形態において、電圧降下部６０の電圧降下率Ｆ６０は、抵抗器Ｒ１に入力された信号Ｓ２の電圧Ｖ２と、抵抗器Ｒ１から出力された接続点６０Ｐの電圧Ｖ４を用いて以下の式で与えられる。
Ｆ６０＝（Ｖ２―Ｖ４）／Ｖ２
　電圧降下部７０の電圧降下率Ｆ７０は、抵抗器Ｒ３に入力された信号Ｓ１の電圧Ｖ１と、抵抗器Ｒ３から出力された接続点７０Ｐの電圧Ｖ３により以下の式で与えられる。
Ｆ７０＝（Ｖ１―Ｖ３）／Ｖ１
　言い換えると、同じ値の電圧が、電圧降下部６０、７０に印加された場合、電圧降下部６０から出力される電圧Ｖ４は、電圧降下部から出力される電圧Ｖ３よりも小さくなる。このように、電圧降下部６０、７０は構成されている。 In the embodiment, the voltage drop rate F60 of the voltage drop unit 60 is expressed by the following equation using the voltage V2 of the signal S2 input to the resistor R1 and the voltage V4 of the connection point 60P output from the resistor R1. Given.
F60 = (V2-V4) / V2
The voltage drop rate F70 of the voltage drop unit 70 is given by the following equation by the voltage V1 of the signal S1 input to the resistor R3 and the voltage V3 of the connection point 70P output from the resistor R3.
F70 = (V1-V3) / V1
In other words, when the voltage having the same value is applied to the voltage drop units 60 and 70, the voltage V4 output from the voltage drop unit 60 is smaller than the voltage V3 output from the voltage drop unit. Thus, the voltage drop parts 60 and 70 are comprised.
　フィルタ回路８０１は、電圧降下部６０と端子３２との間で電気的に接続されている。また、フィルタ回路８０２は、電圧降下部７０と端子３１との間で電気的に接続されている。フィルタ回路８０１は電圧降下部６０から出力された信号Ｓ４のノイズを除去して、ノイズを除去した信号Ｓ４を端子３２に出力する。フィルタ回路８０２は電圧降下部７０から出力された信号Ｓ３のノイズを除去して、ノイズを除去した信号Ｓ３を端子３１に出力する。このように構成することにより、端子３１、３２に入力される信号にノイズが混ざることを抑制できる。 The filter circuit 801 is electrically connected between the voltage drop unit 60 and the terminal 32. Further, the filter circuit 802 is electrically connected between the voltage drop unit 70 and the terminal 31. The filter circuit 801 removes noise from the signal S4 output from the voltage drop unit 60, and outputs the signal S4 from which noise has been removed to the terminal 32. The filter circuit 802 removes noise from the signal S3 output from the voltage drop unit 70, and outputs the signal S3 from which noise has been removed to the terminal 31. By comprising in this way, it can suppress that a noise is mixed with the signal input into the terminals 31 and 32. FIG.
　フィルタ回路８０１が、電圧降下部６０と端子３２との間で電気的に接続され、フィルタ回路８０２が、電圧降下部７０と端子３１との間で電気的に接続されていると好ましい。しかし、フィルタ回路８０１が電圧降下部６０と端子３２との間で電気的に接続されており、かつフィルタ回路８０２が、電圧降下部７０と端子３１との間で電気的に接続されていなくてもよい。また、フィルタ回路８０２が電圧降下部７０と端子３１との間で電気的に接続されており、かつフィルタ回路８０１が電圧降下部６０と端子３２との間で電気的に接続されていなくてもよい。このように、フィルタ回路（８０１、８０２）は、電圧降下部６０と端子３２との間と、電圧降下部７０と端子３１との少なくともいずれか一方の間に電気的に接続されていてもよい。 It is preferable that the filter circuit 801 is electrically connected between the voltage drop unit 60 and the terminal 32, and the filter circuit 802 is electrically connected between the voltage drop unit 70 and the terminal 31. However, the filter circuit 801 is electrically connected between the voltage drop unit 60 and the terminal 32, and the filter circuit 802 is not electrically connected between the voltage drop unit 70 and the terminal 31. Also good. Further, the filter circuit 802 is electrically connected between the voltage drop unit 70 and the terminal 31, and the filter circuit 801 is not electrically connected between the voltage drop unit 60 and the terminal 32. Good. Thus, the filter circuit (801, 802) may be electrically connected between the voltage drop unit 60 and the terminal 32 and between at least one of the voltage drop unit 70 and the terminal 31. .
　駆動部９０は、整流平滑出力部５０と電圧降下部６０との間と電気的に接続されており、電源端子２５とも電気的に接続されている。駆動部９０は、たとえばＤＣ／ＤＣ（Ｄｉｒｅｃｔ　Ｃｕｒｒｅｎｔ／Ｄｉｒｅｃｔ　Ｃｕｒｒｅｎｔ）コンバータである。駆動部９０は、整流平滑出力部５０の出力する電圧Ｖ２を制御部２０を駆動できる電圧に変換して出力する。言い換えれば、駆動部９０は、制御部２０を駆動するための駆動電力Ｐ９０に信号Ｓ２を変換する。これにより、制御システム１００は、制御部２０を駆動するための電力として信号Ｓ２を用いる。 The drive unit 90 is electrically connected between the rectifying and smoothing output unit 50 and the voltage drop unit 60, and is also electrically connected to the power supply terminal 25. The drive unit 90 is, for example, a DC / DC (Direct Current / Direct Current) converter. The drive unit 90 converts the voltage V2 output from the rectifying and smoothing output unit 50 into a voltage that can drive the control unit 20, and outputs the voltage. In other words, the drive unit 90 converts the signal S2 into drive power P90 for driving the control unit 20. Thereby, the control system 100 uses the signal S2 as power for driving the control unit 20.
　電源部１は、たとえば一次電池や二次電池である。電源部１は、直流電力である電力Ｐ１を発生させる。電源部１は、切替部４と負荷部２と電気的に接続されている。 The power supply unit 1 is, for example, a primary battery or a secondary battery. The power supply unit 1 generates power P1 that is DC power. The power supply unit 1 is electrically connected to the switching unit 4 and the load unit 2.
　切替部４は、駆動部９０と電源端子２５との間すなわち電源部１と制御部２０との間で電気的に接続されている。つまり、切替部４は、駆動部９０からも電力Ｐ９０の供給を受けることができ、電源部１からも電力Ｐ１の供給を受けることができる。そして、切替部４は、駆動部９０が電力Ｐ９０を出力した場合に駆動部９０から電源端子２５へ電力Ｐ９０を供給し、駆動部９０が電力Ｐ９０を出力していない場合は電源部１から電源端子２５へ電力Ｐ１を供給する。切替部４は、たとえば、電源端子２５と電源部１との間で電源端子２５へ電力Ｐ１を流せるように接続されたダイオードＤ４２と、電源端子２５と駆動部９０との間で電源端子２５へ電力Ｐ９０を流せるように接続されたダイオードＤ４１とを有する回路（図１参照）である。切替部４は、スイッチや、デジタル制御されるデジタル回路であってもよい。 The switching unit 4 is electrically connected between the drive unit 90 and the power supply terminal 25, that is, between the power supply unit 1 and the control unit 20. That is, the switching unit 4 can also receive the power P90 from the drive unit 90 and can also receive the power P1 from the power supply unit 1. The switching unit 4 supplies the power P90 from the driving unit 90 to the power supply terminal 25 when the driving unit 90 outputs the power P90. When the driving unit 90 does not output the power P90, the switching unit 4 supplies the power from the power source unit 1. Power P1 is supplied to the terminal 25. For example, the switching unit 4 is connected to the power supply terminal 25 between the power supply terminal 25 and the drive unit 90, and the diode D42 connected so that the power P1 can flow to the power supply terminal 25 between the power supply terminal 25 and the power supply unit 1. It is a circuit (refer FIG. 1) which has the diode D41 connected so that the electric power P90 could be sent. The switching unit 4 may be a switch or a digital circuit that is digitally controlled.
　負荷部２は、負荷２Ａと負荷制御回路２Ｂとを有している。負荷２Ａは、たとえば、モータ・ディスプレイ・発光素子などの電源部１の出力する電力Ｐ１によって動作する電子部品である。負荷制御回路２Ｂは、制御部２０からの負荷制御信号によって、負荷２Ａのオン（駆動）とオフ（停止）とを切り替える。 The load unit 2 includes a load 2A and a load control circuit 2B. The load 2 </ b> A is an electronic component that is operated by electric power P <b> 1 output from the power supply unit 1 such as a motor, a display, and a light emitting element. The load control circuit 2B switches on (drive) and off (stop) the load 2A according to a load control signal from the control unit 20.
　なお、実施の形態における制御システム１００では、起動部３０を用いて可変の電圧Ｖ３２で閾値を設定できるが、所定の値に固定された閾値が設定されていてよい。 In the control system 100 according to the embodiment, the threshold value can be set with the variable voltage V32 using the starting unit 30, but a threshold value fixed to a predetermined value may be set.
　このように構成された制御システム１００の動作について説明する。図３Ａと図３Ｂは制御システム１００の動作を示すフローチャートである。図４は制御システム１００の交流信号Ｓａｃと駆動部に入力される電圧ＶＳ２と、切替部４の出力する電圧とを示し、制御システム１００と装置２００の状態も併せて示す。図５と図６はそれぞれ装置２００の模式側面図と模式下面図である。実施の形態における制御システム１００では、負荷２Ａは電源１から供給された電力Ｐ１により光を発する発光ダイオード（ＬＥＤ；ｌｉｇｈｔ　ｅｍｉｔｔｉｎｇ　ｄｉｏｄｅ）等の発光素子である。制御システム１００は、制御システム１００を収納可能なシステム収納部２０１を形成された靴２０１Ａの中に収納されて用いられる。また、制御部２０は、所定の時間Ｔｔｈのみ発光素子を点灯するように構成されている。実施の形態では、検出部５は制御システム１００の周囲の光の照度等の外部環境をセンシングして検出信号を出力する照度センサである。 The operation of the control system 100 configured as described above will be described. 3A and 3B are flowcharts showing the operation of the control system 100. FIG. FIG. 4 shows the AC signal Sac of the control system 100, the voltage VS2 input to the drive unit, and the voltage output by the switching unit 4, and also shows the states of the control system 100 and the apparatus 200. 5 and 6 are a schematic side view and a schematic bottom view of the apparatus 200, respectively. In the control system 100 in the embodiment, the load 2 </ b> A is a light emitting element such as a light emitting diode (LED) that emits light by the electric power P <b> 1 supplied from the power source 1. The control system 100 is used by being housed in a shoe 201 </ b> A in which a system housing 201 capable of housing the control system 100 is formed. Further, the control unit 20 is configured to light the light emitting element only for a predetermined time Tth. In the embodiment, the detection unit 5 is an illuminance sensor that senses an external environment such as illuminance of light around the control system 100 and outputs a detection signal.
　まず図３Ａに示す動作を説明する。制御部２０は、電源部１からの電力Ｐ１を供給されて起動し（ステップＳ１）、待機状態であるディープスリープ状態となる（ステップＳ２）。発信部１０は、外側から力を加えられることにより交流信号Ｓａｃを発生させる。交流信号Ｓａｃは、整流出力部４０を介して端子３１へと至る回路と、整流平滑出力部５０を介して端子３２へと至る回路とに出力される。 First, the operation shown in FIG. 3A will be described. The control unit 20 is activated by being supplied with the electric power P1 from the power supply unit 1 (step S1), and enters a deep sleep state that is a standby state (step S2). The transmitter 10 generates an AC signal Sac when a force is applied from the outside. The AC signal Sac is output to a circuit that reaches the terminal 31 via the rectification output unit 40 and a circuit that reaches the terminal 32 via the rectification smoothing output unit 50.
　起動部３０は端子３１に印加された電圧Ｖ３１と端子３２に印加された電圧Ｖ３２を比較する（ステップＳ３）。ステップＳ３にて電圧Ｖ３１が電圧Ｖ３２よりも大きくない場合には（ステップＳ３の「Ｎｏ」）、起動部３０はステップＳ３にて電圧Ｖ３１、Ｖ３２を比較し続ける。ステップＳ３にて端子３１に印加された電圧Ｖ３１が端子３２に印加された電圧Ｖ３２よりも大きい場合に（ステップＳ３の「Ｙｅｓ」）、起動部３０は、信号Ｓ１を制御部２０の制御素子２４へ出力する。制御部２０の制御素子２４は、起動部３０から信号Ｓ１が出力されたことにより起動して靴の着地を検出し、充電素子５２Ｃに蓄えられた充電電圧ＶＳ２を計測し始める（ステップＳ４）。 The starting unit 30 compares the voltage V31 applied to the terminal 31 with the voltage V32 applied to the terminal 32 (step S3). If the voltage V31 is not greater than the voltage V32 in step S3 (“No” in step S3), the activation unit 30 continues to compare the voltages V31 and V32 in step S3. When the voltage V31 applied to the terminal 31 in step S3 is larger than the voltage V32 applied to the terminal 32 (“Yes” in step S3), the activation unit 30 transmits the signal S1 to the control element 24 of the control unit 20. Output to. The control element 24 of the control unit 20 is activated when the signal S1 is output from the activation unit 30, detects landing of shoes, and starts measuring the charging voltage VS2 stored in the charging element 52C (step S4).
　制御部２０は、充電電圧ＶＳ２または起動部３０から出力された電圧の少なくともいずれか一方を基準に、制御部２０の制御素子２４と接続された照度センサである検出部５を用いて検出部５の周囲の光の照度をセンシングする（ステップＳ５）。制御部２０の制御素子２４は検出部５でセンシングされた照度の値５Ｓを制御部２０に設定された閾値Ｌｔｈと比較する（ステップＳ６）。ステップＳ６にて検出部５でセンシングされた照度の値５Ｓが閾値Ｌｔｈ未満でない場合には（ステップＳ６の「Ｎｏ」）、制御素子２４はステップＳ２にてディープスリープ状態となる。ステップＳ６にて検出部５でセンシングされた照度の値５Ｓが閾値Ｌｔｈ未満である場合には（ステップＳ６の「Ｙｅｓ」）、制御素子２４は、負荷制御回路２Ｂに負荷２Ａへの通電を指示する。これにより、制御システム１００は、発光素子の点灯をすなわち負荷２Ａの動作を開始する（ステップＳ７）。 The control unit 20 uses the detection unit 5 that is an illuminance sensor connected to the control element 24 of the control unit 20 on the basis of at least one of the charging voltage VS2 and the voltage output from the activation unit 30. The illuminance of the ambient light is sensed (step S5). The control element 24 of the control unit 20 compares the illuminance value 5S sensed by the detection unit 5 with the threshold value Lth set in the control unit 20 (step S6). When the illuminance value 5S sensed by the detection unit 5 in step S6 is not less than the threshold value Lth (“No” in step S6), the control element 24 enters a deep sleep state in step S2. When the illuminance value 5S sensed by the detection unit 5 in step S6 is less than the threshold value Lth (“Yes” in step S6), the control element 24 instructs the load control circuit 2B to energize the load 2A. To do. Thereby, the control system 100 starts the lighting of the light emitting element, that is, the operation of the load 2A (step S7).
　制御部２０は、発光素子を点灯させてから経過した時間を計測し（ステップＳ７）、計測された時間を制御部２０の閾値と比較する（ステップＳ８）。ステップＳ８にて計測された時間が制御部２０の閾値を超えていない場合に（ステップＳ８の「Ｎｏ」）、制御部２０はステップ発光素子を点灯し続ける。制御部２０は発光素子を消灯する。そして、計測された時間が制御部２０の閾値を超えた場合に（ステップＳ８の｛Ｙｅｓ｝）、制御部２０は発光素子を消灯する（ステップＳ９）。すなわち、制御部２０は、負荷２Ａを動作させ始めてから経過した時間を計測する。そして、計測された時間が制御部２０の閾値を超えた場合に、制御部２０は負荷２Ａの動作を停止させる。 The control unit 20 measures the time elapsed since the light emitting element was turned on (step S7), and compares the measured time with the threshold value of the control unit 20 (step S8). When the time measured in step S8 does not exceed the threshold value of the control unit 20 (“No” in step S8), the control unit 20 continues to light the step light emitting element. The control unit 20 turns off the light emitting element. When the measured time exceeds the threshold of the control unit 20 ({Yes} in step S8), the control unit 20 turns off the light emitting element (step S9). That is, the control unit 20 measures the time that has elapsed since the load 2A started to operate. When the measured time exceeds the threshold value of the control unit 20, the control unit 20 stops the operation of the load 2A.
　図１および図２の構成においては、制御部２０は電源部１から供給された電力Ｐ１と駆動部９０を用いて発電部３から供給された電力Ｐ３とを受けられるように構成されている。制御部２０が、電源部１から供給された電力Ｐ１から発電部３から供給された電力Ｐ３を切り替える構成について、図３Ｂを参照してさらに説明する。 1 and 2, the control unit 20 is configured to receive the power P1 supplied from the power supply unit 1 and the power P3 supplied from the power generation unit 3 using the drive unit 90. A configuration in which the control unit 20 switches the electric power P3 supplied from the power generation unit 3 from the electric power P1 supplied from the power supply unit 1 will be further described with reference to FIG. 3B.
　駆動部９０は、制御部２０へ供給する電圧へ変換動作を開始するための基準電圧Ｐｈ９０を設定されている。図３Ａに示すステップＳ１において制御部２０が起動し、ステップＳ２においてディープスリープ状態であるときには、制御部２０には電源部１から電力Ｐ１が供給されている（ステップＳ１０１、Ｓ１０２）。具体的には、ステップＳ１０１、Ｓ１０２において、切替部４は電力Ｐ１の電圧からダイオードＤ４２の順方向電圧ＶＦを引いた差の電圧を制御部２０に供給する。駆動部９０は、入力された充電電圧ＶＳ２を閾値電圧Ｐｈ９０と比較する（ステップＳ１０３）。ステップＳ１０３にて発電部３から駆動部９０へ入力された充電電圧ＶＳ２が基準電圧Ｐｈ９０を上回っていない場合に（ステップＳ１０３の「Ｎｏ」）、ステップＳ１０２にて切替部４は電源部１の電力Ｐ１を制御部２０に供給する。ステップＳ１０３にて発電部３から駆動部９０へ入力された充電電圧ＶＳ２が基準電圧Ｐｈ９０を上回った場合に（ステップＳ１０３の「Ｙｅｓ」）、駆動部９０は充電電圧ＶＳ２を変換して駆動電圧Ｖ９０を有する電力Ｐ９０を出力する（ステップＳ１０４）。具体的には、ステップＳ１０４において、切替部４は電力Ｐ９０の電圧からダイオードＤ４１の順方向電圧ＶＦを引いた差の電圧を制御部２０に供給する。 The drive unit 90 is set with a reference voltage Ph90 for starting a conversion operation to a voltage supplied to the control unit 20. When the control unit 20 is activated in step S1 shown in FIG. 3A and is in the deep sleep state in step S2, power P1 is supplied from the power supply unit 1 to the control unit 20 (steps S101 and S102). Specifically, in steps S101 and S102, the switching unit 4 supplies the control unit 20 with a difference voltage obtained by subtracting the forward voltage VF of the diode D42 from the voltage of the power P1. The drive unit 90 compares the input charging voltage VS2 with the threshold voltage Ph90 (step S103). When the charging voltage VS2 input from the power generation unit 3 to the drive unit 90 in step S103 does not exceed the reference voltage Ph90 (“No” in step S103), the switching unit 4 determines that the power of the power supply unit 1 is in step S102. P1 is supplied to the control unit 20. When the charging voltage VS2 input from the power generation unit 3 to the driving unit 90 in step S103 exceeds the reference voltage Ph90 (“Yes” in step S103), the driving unit 90 converts the charging voltage VS2 to convert the driving voltage V90. Is output (step S104). Specifically, in step S104, the switching unit 4 supplies the control unit 20 with a difference voltage obtained by subtracting the forward voltage VF of the diode D41 from the voltage of the power P90.
　駆動部９０が出力する駆動電圧Ｖ９０は、電源部１が制御部２０へ供給する電圧Ｖ１１よりも大きい。そのため、駆動部９０が制御部２０へ電力Ｐ９０を出力している場合、切替部４は駆動部９０からの電力Ｐ９０を制御部２０に供給し、電源部１から制御部２０への電力Ｐ１の供給は擬似的に停止する。 The drive voltage V90 output by the drive unit 90 is higher than the voltage V11 that the power supply unit 1 supplies to the control unit 20. Therefore, when the drive unit 90 outputs power P90 to the control unit 20, the switching unit 4 supplies the power P90 from the drive unit 90 to the control unit 20, and the power P1 from the power supply unit 1 to the control unit 20 is supplied. Supply stops in a pseudo manner.
　駆動部９０は、入力された充電電圧ＶＳ２を閾値電圧Ｐｈ９０と比較する（ステップＳ１０５）。ステップＳ１０５にて発電部３から駆動部９０へ入力された電圧ＶＳ２が基準電圧Ｐｈ９０を上回っている場合に（ステップＳ１０５の「Ｙｅｓ」）、ステップＳ１０４にて切替部４は駆動部９０からの電力Ｐ９０を制御部２０に供給し続ける。ステップＳ１０５にて発電部３から駆動部９０へ入力された電圧ＶＳ２が基準電圧Ｐｈ９０を上回っていない場合に（ステップＳ１０５の「Ｎｏ」）、駆動部９０は動作を停止して電力Ｐ９０を出力しない。そのため、切替部４はステップＳ１０２にて電源部１から制御部２０への電力Ｐ１の供給を擬似的に開始する。 The driving unit 90 compares the input charging voltage VS2 with the threshold voltage Ph90 (step S105). When the voltage VS2 input from the power generation unit 3 to the drive unit 90 in step S105 is higher than the reference voltage Ph90 (“Yes” in step S105), the switching unit 4 receives power from the drive unit 90 in step S104. P90 continues to be supplied to the control unit 20. When the voltage VS2 input from the power generation unit 3 to the drive unit 90 in step S105 does not exceed the reference voltage Ph90 (“No” in step S105), the drive unit 90 stops operating and does not output the power P90. . Therefore, the switching unit 4 artificially starts supplying the power P1 from the power supply unit 1 to the control unit 20 in step S102.
　以上のように制御システム１００は、動作する。そのため、制御システム１００は、常時電力Ｐ１を供給されている場合に比べて省電力な動作を実現できる。また、このような制御システム１００と、負荷２Ａとしての発光素子とを用いた装置２００である靴は、暗い場所で足元から照らすことができたり、他人に存在を知らせることができたりでき、そのため、安全性が向上する。 As described above, the control system 100 operates. Therefore, the control system 100 can realize a power saving operation as compared with the case where the electric power P1 is constantly supplied. In addition, the shoe, which is the device 200 using the control system 100 and the light emitting element as the load 2A, can illuminate from the feet in a dark place and can inform the existence of others. , Improve safety.
　負荷２Ａである発光素子は、アウトソールや、靴底２０３、アッパーソール２０２などにつけることができる。負荷部２は配線２０４で制御システム１００に接続されている。また、発光素子は、発光ダイオードを用いたが、電球でも良い。発光素子は、接着剤などで靴に固定しても良い。 The light emitting element as the load 2A can be attached to the outsole, the shoe sole 203, the upper sole 202, or the like. The load unit 2 is connected to the control system 100 by a wiring 204. Moreover, although the light emitting diode was used for the light emitting element, a light bulb may be used. The light emitting element may be fixed to the shoe with an adhesive or the like.
　制御システム１００は、たとえば照度センサや圧力センサ、ガスセンサなどである検出部５を用いても良い。負荷２Ａは、検出部５の検出結果に応じて決められた所定の動作をしても良い。たとえば、ガスセンサである検出部５が所定値以上の濃度のガスを検出した場合に、負荷２Ａが熱や音や光などによって使用者に知らせるように構成してもよい。また、たとえば、圧力センサである検出部５が所定値以上の圧力を検出した場合に、負荷２Ａが熱や音や光などによって使用者に知らせるように構成してもよい。また、検出部５は複数のセンサを組合せて構成してもよい。これにより、装置２００は、より安全性を向上できる。 The control system 100 may use the detection unit 5 such as an illuminance sensor, a pressure sensor, or a gas sensor. The load 2A may perform a predetermined operation determined according to the detection result of the detection unit 5. For example, when the detection unit 5 that is a gas sensor detects a gas having a concentration equal to or higher than a predetermined value, the load 2A may notify the user by heat, sound, light, or the like. Further, for example, when the detection unit 5 that is a pressure sensor detects a pressure equal to or higher than a predetermined value, the load 2A may notify the user by heat, sound, light, or the like. The detection unit 5 may be configured by combining a plurality of sensors. Thereby, the apparatus 200 can improve safety | security more.
