Description
【０００１】[0001]
本考案は、自動検針動作やセキュリティ動作等をマイクロコンピュータによる 制御部で制御する、ガスメータ等の流量計、特にその電源部の改良に関する。 The present invention relates to an improvement in a flow meter such as a gas meter in which automatic meter reading operation, security operation, and the like are controlled by a control unit of a microcomputer, and particularly to a power supply unit thereof.
【０００２】[0002]
従来のこの種の流量計では、制御部の電源としてリチウム電池を使用していた 。この場合、リチウム電池は、当該流量計の使用期間中に消費されると考えられ る最大値を見込んで、それに応じた容量のものが選択されるが、それにも拘らず 時々予期しない電池消耗により、流量計自体の交換を余儀なくされることがあっ た。また、リチウム電池は、その容量により消費電流の大きさに制限を受け、し かも寸法も比較的大きい上に形状も円筒形であるから、設計上及び電池設置上の 自由度が制約されるという欠点もあった。 In conventional flowmeters of this type, a lithium battery was used as the power source for the control unit. In this case, the lithium battery is selected in consideration of the maximum value that is considered to be consumed during the period of use of the flow meter, and the capacity is selected accordingly, but nevertheless due to unexpected battery consumption, In some cases, the flowmeter itself had to be replaced. In addition, lithium batteries are limited in the amount of current consumption due to their capacity, and because the size is relatively large and the shape is cylindrical, the degree of freedom in design and battery installation is limited. There were also drawbacks.
【０００３】[0003]
そこで、本考案の目的は、このような問題点に鑑み、電池消耗による流量計自 体の交換をなくすとともに、電池による設計上の制約を低減し、かつ電池の厚さ を薄くしかも形状を自由に選べるようにして電池設置上の自由度を向上させるこ とにある。 In view of these problems, the purpose of the present invention is to eliminate the need to replace the flowmeter itself due to battery consumption, reduce the design restrictions imposed by the battery, and reduce the battery thickness and shape. It is intended to improve the degree of freedom in battery installation by making it possible to select.

本考案による流量計では、マイクロコンピュータによる制御部１０の電源とし てポリアニリン等の導電性高分子材料を正極とした二次電池１１を用い、該二次 電池１１を太陽電池１２で充電する構造としたものである。 In the flow meter according to the present invention, a secondary battery 11 having a conductive polymer material such as polyaniline as a positive electrode is used as a power source of a control unit 10 by a microcomputer, and the secondary battery 11 is charged by a solar cell 12. It was done.
【０００５】[0005]
電源として太陽電池１２で充電される二次電池１１を用い、しかも該二次電池 １１としてポリアニリン系電池を使用すると、小型・薄型・軽量、かつ形状の自 由度が高いので、設計上及び電池設置上において有利であるばかりでなく、充電 サイクル特性に優れ、しかも自己放電が少ない上に過放電に強いため、電源部の 寿命を長くできる。 When a secondary battery 11 charged by a solar cell 12 is used as a power source, and a polyaniline-based battery is used as the secondary battery 11, the size, thickness, weight and shape of the secondary battery 11 are high. Not only is it advantageous for installation, it also has excellent charge cycle characteristics, and it has little self-discharge and is resistant to over-discharge, so the life of the power supply section can be extended.
【０００６】[0006]
次に、本考案の一実施例を図面に従い詳細に説明する。 この流量計の電源部は、図１に示すように、マイクロコンピュータによる制御 部（以下、マイコン制御部と記す）１０の電源として、ポリアニリン系電池によ る二次電池１１を用い、該二次電池１１を太陽電池１２により逆流防止用ダイオ ード１３を介して充電する構造になっている。ダイオード１３は、太陽電池１２ の発生電圧の高低によらず、電流が二次電池１１を充電する方向にのみ流れるよ うにする。また、その充電電圧を一定以下に保つためにツェナーダイオード１４ が設けられている。 Next, an embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, the power supply unit of this flowmeter uses a secondary battery 11 made of a polyaniline battery as a power supply for a control unit (hereinafter, referred to as a microcomputer control unit) 10 by a microcomputer. The battery 11 is charged by the solar cell 12 through the backflow prevention diode 13. The diode 13 allows the current to flow only in the direction of charging the secondary battery 11, regardless of the level of the generated voltage of the solar battery 12. Further, a Zener diode 14 is provided to keep the charging voltage below a certain level.
【０００７】 二次電池１１としては、鉛蓄電池やニッケルカドミウム電池も考えられるが、 両者共に小型・薄型・軽量化が難しく、後者は特にカドミウムが公害問題を起こ すので適切とはいえない。これに対して、導電性高分子材料で電極を構成し、ゲ ル状電界質を用いた二次電池は、小型・軽量であり、液漏れしないという優れた 特長を有し、近年実用化されつつある。その中でも、正極にポリアニリン系高分 子材料を使用し、負極としてリチウム又はリチウム合金を使用した二次電池は、 小型・薄型・軽量であるに加え、充電サイクル特性に優れ、しかも自己放電が少 ない上に過放電に強いため、本考案における二次電池１１としては最適である。A lead storage battery or a nickel-cadmium battery can be considered as the secondary battery 11, but it is difficult to reduce the size, thickness, and weight of both batteries, and the latter is not suitable because cadmium causes pollution problems. On the other hand, a secondary battery that uses an electrically conductive polymer material as an electrode and uses a gel-like electrolyte has the advantages of being small and lightweight and not leaking liquid, and has been put to practical use in recent years. It's starting. Among them, a secondary battery using a polyaniline-based high molecular material for the positive electrode and lithium or a lithium alloy for the negative electrode is small, thin, and lightweight, has excellent charge cycle characteristics, and has less self-discharge. In addition, it is suitable for the secondary battery 11 in the present invention because it is strong against over-discharge.
【０００８】 また、太陽電池１２の発電能力は、平均してマイコン制御部１０で消費される 電荷量を少し上回る程度であればよく、二次電池１１の容量としては、満充電状 態で途中の充電なしに１年程度、マイコン制御部１０を有効動作させることがで きれば十分である。Further, the power generation capacity of the solar cell 12 may be a little over the amount of electric charge consumed by the microcomputer controller 10 on average, and the capacity of the secondary battery 11 may be halfway in the fully charged state. It is sufficient if the microcomputer control unit 10 can be effectively operated for about one year without charging.
【０００９】 かかる電源部では、日中、太陽電池１２の発生電圧がダイオード１３による電 圧低下分を差し引いても二次電圧１１の端子電圧より高い場合には、充電が行わ れるが、夜間などの発生電圧が低い場合には、充電が行われずにマイコン制御部 １０で消費される分だけ二次電池１１が放電していくことになる。In such a power supply unit, if the voltage generated by the solar cell 12 is higher than the terminal voltage of the secondary voltage 11 during the day even if the voltage drop due to the diode 13 is subtracted, charging is performed, but at night, etc. When the generated voltage is low, the secondary battery 11 is discharged by the amount consumed by the microcomputer control unit 10 without being charged.
【００１０】 図２及び図３に、ガスメータの場合における二次電池１１及び太陽電池１２の 設置例を示す。この例では、太陽電池１２はガスメータ１５の前面の表示部１６ の上側に設置され、二次電池１１は、太陽電池１２のすぐ裏側において表示部設 置室１７内に設置されている。なお、太陽電池１２の設置個所は、ガスメータ１ ５の上面でもまた側面でも構わない。2 and 3 show examples of installation of the secondary battery 11 and the solar cell 12 in the case of a gas meter. In this example, the solar cell 12 is installed above the display unit 16 on the front surface of the gas meter 15, and the secondary battery 11 is installed in the display unit installation chamber 17 immediately behind the solar cell 12. The solar cell 12 may be installed on the upper surface or the side surface of the gas meter 15.
【００１１】 図４に示す例では、二次電池１１をシート状にして回路基板１８の裏側に設置 した状態を示している。The example shown in FIG. 4 shows a state in which the secondary battery 11 is formed in a sheet shape and installed on the back side of the circuit board 18.

本考案によれば、ポリアニリン等の導電性高分子材料を正極とした二次電池を 用い、該二次電池を太陽電池で充電する構造としたので、二次電池自体が小型・ 薄型・軽量、かつ形状の自由度が高いため、設計上及び電池設置上において有利 である。特に、ポリアニリン系電池は、充電サイクル特性に優れ、しかも自己放 電が少ない上に過放電に強いため、電源部の寿命を長くできる。 According to the present invention, since the secondary battery having the conductive polymer material such as polyaniline as the positive electrode is used and the secondary battery is charged by the solar cell, the secondary battery itself is small, thin and lightweight. In addition, it has a high degree of freedom in shape, which is advantageous in design and battery installation.
