Description

電力供給装置Power supply
　本発明は、太陽光発電を用いて機能部に電力を供給する電力供給装置に関する。 This invention relates to the electric power supply apparatus which supplies electric power to a function part using photovoltaic power generation.
　現在、防災の観点から、地滑り等の観測を行うシステムが各種考案されている。例えば、特許文献１に記載の観測データ回収システムは、複数の解析装置、複数の中継装置、および集約装置を備える。 Currently, various systems for observing landslides have been devised from the viewpoint of disaster prevention. For example, the observation data collection system described in Patent Literature 1 includes a plurality of analysis devices, a plurality of relay devices, and an aggregation device.
　１つの中継装置には複数の解析装置がリンクしている。各中継装置がリンクする解析装置は異なる。集約装置は、複数の中継装置にリンクしている。 中 継 Multiple analysis devices are linked to one relay device. The analysis devices linked to each relay device are different. The aggregation device is linked to a plurality of relay devices.
　中継装置は、自身がリンクしている複数の解析装置の観測データを取得する。中継装置は、取得した複数の観測データをまとめて、集約装置に送信する。 The relay device acquires observation data of multiple analysis devices that it links to. The relay device collects the acquired plurality of observation data and transmits it to the aggregation device.
　解析装置は、中継装置、集約装置とは離れた位置に配置されており、商用電源から電力供給を受けられない位置に配置されることもある。この場合、解析装置は、自装置にて発電を行い、この発電した電力によって観測データの生成および送信を行わなければならない。 The analysis device is arranged at a position away from the relay device and the aggregation device, and may be arranged at a position where power supply from a commercial power source cannot be received. In this case, the analysis device must generate power with its own device, and generate and transmit observation data using the generated power.

　しかしながら、解析装置が配置される位置によって、必要とする電力量は異なることが多い。例えば、無線通信の通信環境が良好であれば通信に係る電力は小さくて済むが、無線通信の通信環境が悪ければ通信に係る電力は大きくなる。 However, the amount of electric power required is often different depending on the position where the analyzer is arranged. For example, if the communication environment for wireless communication is good, the power related to communication is small, but if the communication environment for wireless communication is bad, the power related to communication is large.
　また、解析装置の発電を太陽光発電で行う場合、日照等の環境によって発電量が異なってしまう。したがって、配置位置によって、必要とされる太陽光発電パネルの枚数が異なる。ここで、全ての解析装置において十分に電力をまかなえるようにすると、発電機能部が増長になる解析装置が存在する。一方、最も少ない消費電力の解析装置の発電機能部に合わせると、機能が停止して観測データを送信できない解析装置が存在してしまう。また、それぞれの解析装置に合わせて発電機能部を個別に形成すると、設計、製作費用が嵩んでしまう。また、経時変化によって必要とされる電力量が変化することもあり、解析装置毎に個別に発電機能部を形成したとしても、適切な電力供給を行えるとは限らない。 In addition, when the power generation of the analysis device is performed by solar power generation, the power generation amount varies depending on the environment such as sunshine. Therefore, the required number of photovoltaic power generation panels differs depending on the arrangement position. Here, there is an analysis device in which the power generation function unit is increased if sufficient power is supplied to all the analysis devices. On the other hand, when the power generation function unit of the analysis device with the lowest power consumption is used, there is an analysis device that stops functioning and cannot transmit observation data. In addition, if the power generation function unit is individually formed in accordance with each analysis device, design and manufacturing costs increase. In addition, the amount of power required may change due to changes over time, and even if a power generation function unit is individually formed for each analysis device, appropriate power supply is not always possible.
　したがって、本発明の目的は、設置位置や状況に応じて、適切な回路規模で適切な電力量を供給することができる電力供給装置を提供することにある。 Therefore, an object of the present invention is to provide a power supply device that can supply an appropriate amount of power with an appropriate circuit scale according to the installation position and situation.
　この発明の電力供給装置は、光発電パネル、蓄電池、および充電部を備える。充電部は、光発電パネルの発生する電荷を直流電圧に変換し、蓄電池に充電する。電力供給装置は、さらに、外部から直流電圧が入力される直流電圧入力端子と、直流電圧を出力する直流電圧出力端子とを備える。電力供給装置は、さらに、第１整流器と第２整流器を備える。第１整流器は、直流電圧入力端子と直流電圧出力端子を接続する直流電力ラインに挿入される。第１整流器は、直流電圧入力端子から直流電圧出力端子へ電流を整流する。第２整流器は、第１整流器の直流電圧出力端子側の直流電力ラインと蓄電池との間に接続される。第２整流器は、蓄電池から直流電圧出力端子へ電流を整流する。 The power supply device of the present invention includes a photovoltaic panel, a storage battery, and a charging unit. The charging unit converts the electric charge generated by the photovoltaic panel into a DC voltage and charges the storage battery. The power supply device further includes a DC voltage input terminal to which a DC voltage is input from the outside, and a DC voltage output terminal that outputs the DC voltage. The power supply device further includes a first rectifier and a second rectifier. The first rectifier is inserted into a DC power line connecting the DC voltage input terminal and the DC voltage output terminal. The first rectifier rectifies current from the DC voltage input terminal to the DC voltage output terminal. The second rectifier is connected between the DC power line on the DC voltage output terminal side of the first rectifier and the storage battery. The second rectifier rectifies current from the storage battery to the DC voltage output terminal.
　この構成では、上記機能部からなる回路を単位発電ユニットとし、供給すべき電力量に応じた個数を用意する。前段の単位発電ユニットの直流電圧出力端子を後段の直流電圧入力端子に接続する。すなわち、複数の単位発電ユニットをカスケード接続する。これにより、適切な回路規模で適切な電力量を供給することができる。 In this configuration, the circuit composed of the above functional units is used as a unit power generation unit, and a number corresponding to the amount of power to be supplied is prepared. Connect the DC voltage output terminal of the front unit power generation unit to the DC voltage input terminal of the rear stage. That is, a plurality of unit power generation units are cascade-connected. Thereby, it is possible to supply an appropriate amount of power with an appropriate circuit scale.
　また、この発明の電力供給装置は、データ入力端子、データ出力端子、および、データ入力端子とデータ出力端子を接続するデータ通信バスを備える。充電部は、データ通信バスに接続されている。 The power supply device of the present invention includes a data input terminal, a data output terminal, and a data communication bus that connects the data input terminal and the data output terminal. The charging unit is connected to the data communication bus.

　図２は、本発明の第１の実施形態に係る電力供給部のブロック図である。図３は、本発明の第１の実施形態に係る電力供給部を構成する単位発電ユニットのブロック図である。 FIG. 2 is a block diagram of the power supply unit according to the first embodiment of the present invention. FIG. 3 is a block diagram of a unit power generation unit constituting the power supply unit according to the first embodiment of the present invention.
　図２に示すように、電力供給部６０は、単位発電ユニット６１０，６２０，６３０を備える。単位発電ユニット６１０，６２０，６３０は、図３に示す単位発電ユニット６００の構成を備える。 2, the power supply unit 60 includes unit power generation units 610, 620, and 630. The unit power generation units 610, 620, and 630 have the configuration of the unit power generation unit 600 shown in FIG.
　図３に示すように、単位発電ユニット６００は、光発電パネル６０１、充電部６０２、蓄電池６０３、整流器６０４，６０５、直流電圧入力端子Ｐｉｎ、および、直流電圧出力端子Ｐｏｕｔを備える。 As shown in FIG. 3, the unit power generation unit 600 includes a photovoltaic power generation panel 601, a charging unit 602, a storage battery 603, rectifiers 604 and 605, a DC voltage input terminal Pin, and a DC voltage output terminal Pout.
　光発電パネル６０１は、充電部６０２に接続されている。充電部６０２は蓄電池６０３に接続されている。蓄電池６０３は、整流器６０４（本発明の第２整流器）を介して直流電圧出力端子Ｐｏｕｔに接続されている。直流電圧入力端子Ｐｉｎと直流電圧出力端子Ｐｏｕｔは、整流器６０５（本発明の第１整流器）を介して接続されている。整流器６０４の直流電圧出力端子Ｐｏｕｔ側の電力伝送ラインと、整流器６０５の直流電圧出力端子Ｐｏｕｔ側の電力伝送ラインは接続されている。 The photovoltaic panel 601 is connected to the charging unit 602. Charging unit 602 is connected to storage battery 603. The storage battery 603 is connected to the DC voltage output terminal Pout via the rectifier 604 (second rectifier of the present invention). The DC voltage input terminal Pin and the DC voltage output terminal Pout are connected via a rectifier 605 (first rectifier of the present invention). The power transmission line on the DC voltage output terminal Pout side of the rectifier 604 and the power transmission line on the DC voltage output terminal Pout side of the rectifier 605 are connected.
　光発電パネル６０１は、照射された光量に応じて電荷を発生する。充電部６０２は、光発電パネルで発した電荷を直流電圧に変換する。充電部６０２は、ＭＰＰＴ制御等を行うことによって、光発電パネル６０１の発生した電荷を直流電圧に変換する。充電部６０２は、変換した直流電圧を、蓄電池６０３の充電電圧に変換して、蓄電池６０３に供給する。蓄電池６０３は、充電部６０２からの充電電圧によって充電されるとともに、整流器６０４を介して、直流電圧出力端子Ｐｏｕｔに直流電圧を供給する。 The photovoltaic panel 601 generates electric charge according to the amount of light irradiated. The charging unit 602 converts the charge generated by the photovoltaic panel into a DC voltage. The charging unit 602 converts the electric charge generated by the photovoltaic panel 601 into a DC voltage by performing MPPT control or the like. The charging unit 602 converts the converted DC voltage into a charging voltage for the storage battery 603 and supplies it to the storage battery 603. The storage battery 603 is charged by the charging voltage from the charging unit 602 and supplies a DC voltage to the DC voltage output terminal Pout via the rectifier 604.
　整流器６０４は、蓄電池６０３から直流電圧出力端子Ｐｏｕｔに電流が流れるように回路が構成されている。例えば、整流器６０４は、蓄電池６０３に接続するアノードと、直流電圧出力端子Ｐｏｕｔに接続するカソードを備えるダイオードからなる。 The circuit of the rectifier 604 is configured such that a current flows from the storage battery 603 to the DC voltage output terminal Pout. For example, the rectifier 604 includes a diode having an anode connected to the storage battery 603 and a cathode connected to the DC voltage output terminal Pout.
　整流器６０５は、直流電圧入力端子Ｐｉｎから直流電圧出力端子Ｐｏｕｔに電流が流れるように回路が構成されている。例えば、整流器６０５は、直流電圧入力端子Ｐｉｎに接続するアノードと、直流電圧出力端子Ｐｏｕｔに接続するカソードを備えるダイオードからなる。 The rectifier 605 has a circuit configured such that a current flows from the DC voltage input terminal Pin to the DC voltage output terminal Pout. For example, the rectifier 605 includes a diode having an anode connected to the DC voltage input terminal Pin and a cathode connected to the DC voltage output terminal Pout.
　このような構成とすることによって、単位発電ユニット６００は、蓄電池６０３に蓄電されている電力が十分であり、蓄電池６０３から出力可能な電圧が直流電圧入力端子Ｐｉｎから入力される直流電圧よりも高ければ、蓄電池６０３から直流電圧出力端子Ｐｏｕｔに、直流電圧（直流電力）を供給する。 With this configuration, the unit power generation unit 600 has sufficient power stored in the storage battery 603, and the voltage that can be output from the storage battery 603 is higher than the DC voltage input from the DC voltage input terminal Pin. For example, a DC voltage (DC power) is supplied from the storage battery 603 to the DC voltage output terminal Pout.
　一方、単位発電ユニット６００は、蓄電池６０３の蓄電量が不十分で、蓄電池６０３から出力可能な電圧が直流電圧入力端子Ｐｉｎから入力される直流電圧よりも低くれば、直流電圧入力端子Ｐｉｎから直流電圧出力端子Ｐｏｕｔに、直流電圧（直流電力）を供給する。 On the other hand, in the unit power generation unit 600, if the amount of power stored in the storage battery 603 is insufficient and the voltage that can be output from the storage battery 603 is lower than the DC voltage input from the DC voltage input terminal Pin, the DC from the DC voltage input terminal Pin A DC voltage (DC power) is supplied to the voltage output terminal Pout.
　電力供給部６０は、このような構成からなる単位発電ユニット６００（６１０，６２０，６３０）を、図２に示すように接続する。 The power supply unit 60 connects the unit power generation units 600 (610, 620, 630) having such a configuration as shown in FIG.
　具体的には、単位発電ユニット６１０の直流電圧出力端子Ｐｏｕｔを子機２０の各機能部に接続されている。単位発電ユニット６２０の直流電圧出力端子Ｐｏｕｔを単位発電ユニット６１０の直流電圧入力端子Ｐｉｎに接続されている。単位発電ユニット６３０の直流電圧出力端子Ｐｏｕｔを単位発電ユニット６３０の直流電圧入力端子Ｐｉｎに接続されている。言い換えれば、単位発電ユニット６３０，６２０，６１０は、この順でカスケード接続されている。 Specifically, the DC voltage output terminal Pout of the unit power generation unit 610 is connected to each functional unit of the slave unit 20. The DC voltage output terminal Pout of the unit power generation unit 620 is connected to the DC voltage input terminal Pin of the unit power generation unit 610. The DC voltage output terminal Pout of the unit power generation unit 630 is connected to the DC voltage input terminal Pin of the unit power generation unit 630. In other words, the unit power generation units 630, 620, and 610 are cascade-connected in this order.
　このような構成とすることによって、子機２０の必要な電力量に応じて、電力供給部６０を構成する単位発電ユニットの個数を適宜調整することができる。すなわち、消費電力量が小さな子機２０に対しては、カスケード接続する単位発電ユニットの個数を少なくする。一方、消費電力量が大きな子機２０に対しては、カスケード接続する単位発電ユニットの個数を多くする。 With such a configuration, the number of unit power generation units constituting the power supply unit 60 can be appropriately adjusted according to the amount of power required by the slave unit 20. That is, the number of unit power generation units to be cascade-connected is reduced for the slave unit 20 with a small amount of power consumption. On the other hand, the number of unit power generation units to be cascade-connected is increased for the slave unit 20 that consumes a large amount of power.
　これによって、回路構成が増長にならず、必要な電力量を供給できる電力供給部６０を、子機毎に設置することができる。 Thus, the power supply unit 60 that can supply a necessary amount of power without increasing the circuit configuration can be installed for each slave unit.
　また、本実施形態の構成を用いることによって、経時的に必要な電力量が変化したときに、電力供給部６０の全体を取り替える必要はなく、単位発電ユニットの個数を調整するだけでよい。特に、必要な電力量が多くなった場合、発電量を増加させる必要があるが、本実施形態の構成を用いることによって、必要数の単位発電ユニットを増設すればよく、電力供給部６０の仕様を容易に適正化することができる。特に、地滑り検出システムでは、作業が容易でない山中に子機２０が配置されることが多いが、この構成を用いることによって、子機２０の電力量に応じた電力供給部６０を容易な作業によって実現できる。 In addition, by using the configuration of the present embodiment, when the amount of power required over time changes, it is not necessary to replace the entire power supply unit 60, and it is only necessary to adjust the number of unit power generation units. In particular, when the required amount of power increases, it is necessary to increase the amount of power generation. However, by using the configuration of the present embodiment, a required number of unit power generation units may be added, and the specifications of the power supply unit 60 are as follows. Can be easily optimized. In particular, in the landslide detection system, the handset 20 is often arranged in a mountain where the work is not easy. However, by using this configuration, the power supply unit 60 corresponding to the amount of power of the handset 20 can be easily worked. realizable.
　また、本実施形態の構成を用いることによって、設置された環境の変化に応じて適切に電力を供給することができる。これによって、子機の動作時間をできる限り長くし、観測データの送信を継続することができる。例えば、積雪等によって発電および充電ができないような状況になっても、上述の複数の単位発電ユニットのカスケード接続によって、供給電力が自動的に調整され、適切な電力の供給を実現することができる。 Also, by using the configuration of the present embodiment, it is possible to supply power appropriately according to changes in the installed environment. Thereby, the operation time of the slave unit can be made as long as possible, and the transmission of the observation data can be continued. For example, even if it becomes a situation where power generation and charging cannot be performed due to snow or the like, the supply power is automatically adjusted by the cascade connection of the plurality of unit power generation units described above, and appropriate power supply can be realized. .
　なお、上述の説明では、子機２０の電力供給部６０について示したが、親機３０の電力供給部６０も同様の構成からなる。これによって、親機３０に対して、回路構成が増長にならず、必要な電力量を供給できる電力供給部６０を実現できる。 In the above description, the power supply unit 60 of the child device 20 is shown, but the power supply unit 60 of the parent device 30 has the same configuration. As a result, the power supply unit 60 that can supply the necessary amount of power to the parent device 30 without increasing the circuit configuration can be realized.
　次に、本発明の第２の実施形態に係る電力供給装置を含む観測システムについて、図を参照して説明する。図４は、本発明の第２の実施形態に係る電力供給部を構成する単位発電ユニットのブロック図である。図５は、本発明の第２の実施形態に係る電力供給部のブロック図である。 Next, an observation system including a power supply device according to the second embodiment of the present invention will be described with reference to the drawings.

The DC voltage output terminal Pout of the unit power generation unit 620A is connected to the DC voltage input terminal Pin of the unit power generation unit 610. The DC voltage output terminal Pout of the unit power generation unit 630A is connected to the DC voltage input terminal Pin of the unit power generation unit 630A. In other words, the power supply function units in the unit power generation units 630A, 620A, and 610A are cascade-connected in this order.
　さらに、単位発電ユニット６１０Ａのデータ出力端子ＰｏｕｔＤは、子機２０の制御部２１に接続されている。単位発電ユニット６２０Ａのデータ出力端子ＰｏｕｔＤは、単位発電ユニット６１０Ａのデータ入力端子ＰｉｎＤに接続されている。単位発電ユニット６３０Ａのデータ出力端子ＰｏｕｔＤは、単位発電ユニット６２０Ａのデータ入力端子ＰｉｎＤに接続されている。この構成によって、単位発電ユニット６１０Ａ，６２０Ａ，６３０Ａの充電部６０２は、データ通信バス６０６を介して制御部２１に接続されている。 Furthermore, the data output terminal PoutD of the unit power generation unit 610A is connected to the control unit 21 of the slave unit 20.
