【発明の属する技術分野】
本発明は、例えば発光ダイオード等を用いた自発光式の道路鋲や道路標識等の電源装置として好適に用いられる太陽電池装置に関するものである。
【０００２】
【従来の技術】
発光ダイオード等を用いた自発光式の道路鋲や道路標識等においては、電源装置として太陽電池を用いた太陽電池装置が一般に用いられている。従来、かかる太陽電池装置は、負荷毎に設計されたものであって、複数の太陽電池を線で直接に直列又は並列に接続し、負荷に応じて予め設計された一定の電力や電圧が出力されるようになされている。
【０００３】
【発明が解決しようとする課題】
かように従来の太陽電池装置は負荷毎に設計された一定の電力や電圧が出力されるように、複数の太陽電池が線で直接に直列又は並列に接続されて変更することができないようになされており、出力される電力や電圧の変更はできないものであって、汎用性がなく、電力や電圧の異なる他の負荷への転用ができなかった。また複数の太陽電池の一部に汚れや傷が発生してその太陽電池の出力が低下した場合は、その不良の太陽電池によって装置全体としての出力が低下する問題があるが、各太陽電池は線で直接接続されているために、不良の太陽電池を切り離すことが容易でなく、また各太陽電池の出力も個別に検出されるようになされていないために、不良の太陽電池が存在するか否かも容易に検出することができなかった。
【０００４】
そこで本発明は、上記の如き問題点を解決し、汎用性があり、電力や電圧の異なる各種負荷への使用が可能であり、また不良の太陽電池の存在を検出し、その太陽電池を切り離すことができる太陽電池装置を提供せんとするものである。
【０００５】
【課題を解決するための手段】
上記目的を達成するために、本発明は次のような構成としている。
すなわち本発明に係る太陽電池装置は、２個の太陽電池のそれぞれのプラス側とマイナス側に２接点の切換スイッチが接続されると共に、一方の太陽電池のプラス側に接続された２接点の切換スイッチと他方の太陽電池のプラス側に接続された２接点の切換スイッチとの間に単接点の開閉スイッチが接続され、前記２接点の切換スイッチと前記単接点の開閉スイッチとを制御することにより、前記２個の太陽電池を直列接続又は並列接続に切り換えることができるようになされ、及びいずれか一方の太陽電池を接続し、他方の太陽電池の接続を切り離すことができるようにもなされ、且つ出力側に出力電力を検知する出力電力監視回路が設けられていることを特徴とするものである。
【０００６】
本発明によれば、切換スイッチ及び開閉スイッチを制御することにより、太陽電池は直列接続、並列接続、直列と並列の組合わせ接続、単一接続、又は切り離し等、接続状態を適宜切り換えることができるので、汎用性があり、電力や電圧の異なる各種負荷への使用が可能である。
【０００７】
また出力側に出力電力を検知する出力電力監視回路が設けられているので、接続状態を切り換える際における出力電力の検知が容易であり、素早く各種負荷への対応ができ、さらに前記切換スイッチ及び開閉スイッチを制御して各太陽電池を順次単一接続の状態にすれば、各太陽電池の出力を順次個別に検知することができるため、この検知した各太陽電池の出力に基づいて不良の太陽電池の存在を検出し、その不良の太陽電池を切り離して常に最適の状態で電力を出力させることもできる。
【０００８】

【００１４】
なお前記切換スイッチＳＷ１〜ＳＷ４及び開閉スイッチＳＷ５〜ＳＷ６及びＳＷ１３〜ＳＷ１７の制御については、外部より接続したコントロール装置によって制御してもよいが、切換スイッチＳＷ１〜ＳＷ４及び開閉スイッチＳＷ５〜ＳＷ６及びＳＷ１３〜ＳＷ１７については、リレー、半導体リレー、トランジスター、ＦＥＴ等、好適には低消費型にした保持型のラッチングタイプを用いると共に、出力電力監視回路ＣＨ１にコントロール回路を設け、検知された出力電力に基づいて太陽電池Ｃ１，Ｃ２の接続状態を適宜切り換えるべく前記切換スイッチＳＷ１〜ＳＷ４及び開閉スイッチＳＷ５〜ＳＷ６及びＳＷ１３〜ＳＷ１７が、このコントロール回路によって制御されるようになされていてもよい。

【００１７】
本形態において、切換スイッチＳＷ１〜ＳＷ４及びＳＷ７〜ＳＷ１０及び開閉スイッチＳＷ５〜ＳＷ６及びＳＷ１１〜ＳＷ１７の接点状態における、太陽電池Ｃ１〜Ｃ４の接続状態の一例を表１で表した。なお表１において、Ａ及びＢは、切換スイッチＳＷ１〜ＳＷ４及びＳＷ７〜ＳＷ１０をＡ接点側に接続した状態をＡで示し、Ｂ接点側にした場合をＢで示し、またオン及びオフは、開閉スイッチＳＷ５〜ＳＷ６及びＳＷ１１〜ＳＷ１７をオン又はオフした状態であることを示し、−はＡ接点、Ｂ接点、オンオフどちらでもよい状態を示している。

BACKGROUND OF THE INVENTION
The present invention relates to a solar cell device that is suitably used as a power supply device such as a self-luminous roadway or a road sign using, for example, a light emitting diode.
[0002]
[Prior art]
In a self-light-emitting roadway or a road sign using a light emitting diode or the like, a solar cell device using a solar cell as a power supply device is generally used. Conventionally, such a solar cell device is designed for each load, and a plurality of solar cells are directly connected in series or in parallel by wires, and a predetermined power or voltage designed in advance according to the load is output. It is made to be done.
[0003]
[Problems to be solved by the invention]
In this way, the conventional solar cell device cannot be changed by connecting a plurality of solar cells directly in series or in parallel so that constant power and voltage designed for each load are output. Therefore, the output power and voltage cannot be changed, and are not versatile, and cannot be diverted to other loads having different power and voltage. In addition, when dirt or scratches occur on some of the solar cells and the output of the solar cell decreases, there is a problem that the output of the entire device decreases due to the defective solar cell. Is it not easy to separate the defective solar cells because they are directly connected by wires, and the output of each solar cell is not individually detected, so there is a defective solar cell? Neither could it be detected easily.
[0004]
Therefore, the present invention solves the above-mentioned problems, is versatile, can be used for various loads with different power and voltage, detects the presence of a defective solar cell, and disconnects the solar cell. It is an object of the present invention to provide a solar cell device that can be used.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is configured as follows.
That is, in the solar cell device according to the present invention, a two-contact changeover switch is connected to the plus side and the minus side of two solar cells, and a two-contact changeover connected to the plus side of one solar cell. A single contact opening / closing switch is connected between the switch and the two contact switching switch connected to the positive side of the other solar cell, and the two contact switching switch and the single contact opening / closing switch are controlled. The two solar cells can be switched to a series connection or a parallel connection, and one of the solar cells can be connected and the other solar cell can be disconnected, and An output power monitoring circuit for detecting output power is provided on the output side.
[0006]
According to the present invention, by controlling the changeover switch and the open / close switch, the solar cell can appropriately switch the connection state such as series connection, parallel connection, combination connection in series and parallel, single connection, or disconnection. Therefore, it is versatile and can be used for various loads with different power and voltage.
[0007]
In addition, since an output power monitoring circuit for detecting output power is provided on the output side, it is easy to detect the output power when switching the connection state, and can quickly respond to various loads. If each solar cell is sequentially brought into a single connection state by controlling the switch, the output of each solar cell can be individually detected sequentially, so that a defective solar cell is based on the detected output of each solar cell. Can be detected, and the defective solar cell can be disconnected to always output power in an optimum state.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be specifically described below with reference to the drawings.
FIG. 1 is a circuit configuration diagram showing an embodiment of the present invention, and FIG. 2 is a circuit configuration diagram showing another embodiment.
[0009]
First, in FIG. 1, C1 and C2 are solar cells, and two are provided. Solar cells C1 and C2 are not particularly limited, and solar cells C1 and C2 are suitably used, such as single crystal or polycrystalline crystalline silicon solar cells, amorphous amorphous silicon solar cells, and compound semiconductor solar cells. . The solar cells C1 and C2 may be cells or modules.
[0010]
Next, SW1 to SW4 are changeover switches having two contacts, that is, at least an A contact and a B contact, and SW5 to SW6 and SW13 to SW17 are single contact open / close switches that perform an on / off operation. T1 and T2 are output terminals to which a load is connected, T1 is a ground line, T2 is a power supply line, and T3 to T5 and T8 are circuits in FIG. 1 connected in parallel, in series connection or similar to the present invention. It is an external connection terminal for connecting another solar cell device having a function. The on / off switches SW13 and SW14 are for disconnecting the load of the output terminals T1 and T2 when the outputs of the solar cells C1 and C2 are detected, and the on / off switches SW15 to SW17 are connected to the external connection terminals T3 to T4 and T8. This is for disconnecting other external connection devices. Note that a load may be directly connected to the output terminals T1 and T2, or may be connected via another circuit or device such as a power storage device.
[0011]
The changeover switches SW1 to SW4 and the open / close switches SW5 to SW6 and SW13 to SW17 connect the solar cells C1 and C2 to form a predetermined circuit. The changeover switches SW1 to SW4 and the open / close switches SW5 to SW6 and SW13 to SW17 are connected. By controlling the solar cells C1 and C2, the connection state such as series connection, parallel connection, combination connection in series and parallel, single connection, or disconnection can be appropriately switched, and the power and voltage according to the load can be changed. The output is output from the output terminals T1 and T2, and the load and the external connection can be disconnected.
[0012]
T6 to T7 are output power monitoring circuit connection terminals. The output power monitoring circuit CH1 is connected to the output power monitoring circuit connection terminals T6 to T7. The output power monitoring circuit CH1 outputs the output power from the output terminals T1 and T2. Electric power, voltage, etc. are detected.
[0013]
Therefore, if the changeover switches SW1 to SW4 and the open / close switches SW5 to SW6 and SW13 to SW17 are controlled so that the solar cells C1 and C2 are sequentially connected to each other, the outputs of the solar cells C1 and C2 are individually detected in order. In addition, the presence of a defective solar cell can be detected based on the detected output of each of the solar cells C1 and C2, and the defective solar cell can be disconnected to always output power in an optimum state. . Furthermore, when switching the connection state, the output power is detected, so the solar cells C1 and C2 are connected in series, in parallel, and in series and in parallel, in response to various loads while detecting the output power. By appropriately switching the connection state such as single connection or disconnection, it is possible to output power or voltage corresponding to the load.
[0014]
The change-over switches SW1-SW4 and the open / close switches SW5-SW6 and SW13-SW17 may be controlled by a control device connected from the outside, but the change-over switches SW1-SW4 and open / close switches SW5-SW6 and SW13- For SW17, a holding type latching type, preferably a low-consumption type, such as a relay, semiconductor relay, transistor, FET, etc. is used, and a control circuit is provided in the output power monitoring circuit CH1, and based on the detected output power The changeover switches SW1 to SW4 and the open / close switches SW5 to SW6 and SW13 to SW17 may be controlled by this control circuit in order to appropriately switch the connection state of the solar cells C1 and C2.
[0015]
Next, the form shown in FIG. 2 will be described.
2 is a circuit in which the circuit shown in FIG. 1 is connected in parallel, and in this embodiment, four solar cells C1 to C4 are provided, and these four solar cells C1 to C4 are provided. Are connected by at least two-contact change-over switches SW1 to SW4 and SW7 to SW10 having an A contact and a B contact, and single contact opening / closing switches SW5 to SW6 and SW11 to SW17 that perform on / off operations, and FIG. Similarly, T1 and T2 are output terminals connected to a load, T3 to T5 are external connection terminals, and CH1 is an output power monitoring circuit provided with a control circuit.
[0016]
2, the solar cells C1 to C4 are connected in series, in parallel, and in series and parallel by controlling the selector switches SW1 to SW4 and SW7 to SW10 and the open / close switches SW5 to SW6 and SW11 to SW17. The connection state can be switched as appropriate, such as combined connection, single connection, or disconnection, and power and voltage corresponding to the load are output from the output terminals T1 and T2, and the load and external connection are disconnected. It has been made so that it can.
[0017]
In this embodiment, an example of the connection state of the solar cells C1 to C4 in the contact state of the changeover switches SW1 to SW4 and SW7 to SW10 and the open / close switches SW5 to SW6 and SW11 to SW17 is shown in Table 1. In Table 1, A and B indicate the state in which the changeover switches SW1 to SW4 and SW7 to SW10 are connected to the A contact side, and A indicates the B contact side, and B indicates the on / off state. This indicates that the switches SW5 to SW6 and SW11 to SW17 are turned on or off, and − indicates a state in which any of the A contact, the B contact, and the on / off may be performed.
[0018]
For example, Table 1 will be specifically described when the connection state is “4 series”.
“4 series” is a case where all four solar cells C1 to C4 are connected in series. In this case, the contact states of the changeover switches SW1 to SW3 and SW8 to SW10 are the A contact, the changeover switch SW4 and SW7 is connected to the B contact side, the open / close switches SW6, SW12, and SW17 are turned off, and the open / close switches SW5, SW11, SW15, and SW16 may be either on or off.
[0019]
[Table 1]
As shown in Table 1, by controlling the selector switches SW1 to SW4 and SW7 to SW10 and the open / close switches SW5 to SW6 and SW11 to SW17, the solar cells C1 to C4 are connected in series, connected in parallel, and a combination of series and parallel. The connection state, such as connection, single connection, or disconnection, can be switched as appropriate, and power and voltage corresponding to the load can be quickly switched and output. In addition, the output states of the individual solar cells C <b> 1 to C <b> 4 can be confirmed by setting the contact states shown in “when C1 output is detected” and “when C2 output is detected” in Table 1 respectively.
[0021]
The basic configuration of the circuit of FIG. 1 and the configuration of FIG. 2 are two circuits connected in parallel. However, the present invention is not limited to this. Any number of circuits can be connected in series, parallel, or in series and parallel. They may be connected together.
[0022]
【The invention's effect】
According to the present invention, by controlling the changeover switch and the open / close switch, each solar cell can appropriately switch the connection state such as series connection, parallel connection, combination connection in series and parallel, single connection, or disconnection. Therefore, it is versatile and can be used for various loads with different power and voltage.
[0023]
In addition, since an output power monitoring circuit for detecting output power is provided on the output side, it is easy to detect the output power when switching the connection state, and can quickly respond to various loads. If each solar cell is sequentially brought into a single connection state by controlling the switch, the output of each solar cell can be individually detected sequentially. Therefore, a defective solar cell is based on the detected output of each solar cell. Can be detected, and the defective solar cell can be disconnected to always output power in an optimum state.
