Description

【０００１】
【発明の属する技術分野】
本発明は水道の使用量を示す積算メータの値を、無線通信を利用して検針するようにした通信機に防水機能を持たせた防水カバーを持った水道メータ検針用無線通信機に関する。
本発明の防水カバーを持った水道メータ検針用無線通信機は、大雨等により積算メータの設置場所が浸水した場合にも通信機能を確保出来、安定した検針作業を可能にしたものである。
【０００２】
【従来の技術】
水道の使用量を示す各種メータの積算値の検針を行う業務においては、それぞれのメータが設置されている環境も様々であることから、メーターが検針員による目視検針が容易でない環境に設置されている場合も多々ある。このような検針困難な状況に設置されているメータの検針作業を容易にするために、無線通信手段を用いた無線検針システムの実施運用も種々試行されている。このような無線検針システムを活用することにより、検針困難な水道メータへの対応救済が可能となるばかりでなく、検針作業効率も改善されるなどの相応の評価が得られるようになってきている。
近年の無線応用技術の急速な進歩に伴い、無線機器のコストやその設置工事費用が低廉となって来たために、水道メータ検針用無線通信機器を利用した検針システムの実現への期待が高まっており、種々の無線検針システムが試験的に使用され始めている。
【０００３】
従来の水道メータの無線検針システムの全体構成を図４に示す。図４において、１は水道メータ、２はメータ１に接続される子局の水道メータ検針用無線通信機器、３は検針者が携帯する水道メータ検針用無線通信機に接続されたハンディターミナルである。子局の水道メータ検針用無線通信機器２は、無線回路１１、制御回路１２、電池１３及びアンテナ１５により構成され、各水道メータにはそれぞれこれを特定するアドレス番号が設定されている。
水道メータの無線検針システムによる検針作業は、例えば訪問検針作業では、検針者が検針を行なうメータの近隣まで近づいて、そのメータのアドレス（ＩＤ）番号をハンディターミナル３に設定した後、ハンディターミナル３より、通信要求を出して指定されたアドレス（ＩＤ）番号のメータに接続される子局の水道メータ検針用無線通信機２を呼び出し、そのメータの積算値を無線でハンディターミナル３で読み取ることにより行われる。
【０００４】
子局の水道メータ検針用無線通信機２は、低消費電力のマイクロプロセッサと、極めて僅かの電力しか消費しない若干の周辺回路のみによって構成され、全体での消費電力は小さな値に設定されている。子局の水道メータ検針用無線通信機２の電池は、長期の保存性能を有し一般的に入手が容易なリチウム一次電池が使用される。
無線検針システムにあっては、設置の容易性及び運用コストの低廉性という無線システムの長所を最大限に生かすために、電源に内蔵電池を使用し、且つ計量法によるメータの交換サイクルである８年〜１０年間にわたり、電池を交換することなく運用するために、消費電力の少ない極めて微弱な電波を使用している。（特許第３２６４６４２号）
【０００５】
【発明が解決しようとする課題】
水道メータの無線検針システムは、検針員による目視検針が容易でない環境、例えば雪国において積雪期にメーターが雪に覆われいるような検針困難な状況にある水道メータの検針作業を容易にすることが大きな利点である。
しかしながら、消費電力の少ない極めて微弱な電波を使用した水道メータ検針用無線通信機は、図５に示すように、雪解水や常時流されている融雪水、大雨等により積算メータＭＴの設置場所のメーターボックスＭＢが浸水した場合には、水道メータ検針用無線通信機１０に防水を施しても、アンテナ１５の部分が水没するレベルまでメーターボックスＭＢの浸水が進と、水により電波が減衰するため、検針用のハンディターミナル３との通信が確保出来なくなる問題があり、このような検針困難な状況に設置された水道メータの無線検針システムを安定して運用する技術は実用化される段階には至っていない。
このため、水道メータの無線検針システムは、現在でも実質的に試行的な領域から出られない状況が長く続いており、その結果、真に実用に耐え得る水道メータの無線検針システムの実現が広く待望されている。
【０００６】
【課題を解決するための手段】
本発明は、水道の使用量を示す積算メータの値を、無線通信を利用して検針するようにした水道メータの無線検針システムにおいて、
水道メータ検針用無線通信機のアンテナ部分に浸水時にアンテナ部分が水面上に浮上する浮力を持った空間を設けて、水道メータ検針用無線通信機本体とアンテナを一体として防水カバーにより密封被覆して、雪解水や常時流されている融雪水、大雨等により積算メータの設置場所が浸水した場合には、水道メータ検針用無線通信機が浮上してアンテナ部分が水面上に出るようにして、通信が確保出来るようにして無線検針システムを安定して運用出来るようにしたものである。
【０００７】
【発明の実施の形態】
【実施例】
図１及び図２は、本発明の防水カバーを持った水道メータ検針用無線通信機の構成を説明する無線通信機本体外函の斜視図である。
図１の実施例は、水道メータ検針用無線通信機本体が角型の場合の例を示したもので、図２の実施例は、水道メータ検針用無線通信機本体が平型の場合の例を示したものである。
図１及び図２において、１０は水道メータ検針用無線通信機、２０は水道メータ検針用無線通信機のアンテナである。３０は水道メータ検針用無線通信機１０と水道メータを接続する信号線て、４０は水道メータ検針用無線通信機本体とアンテナを一体として覆う防水カバーである。防水カバー４０は、水道メータ検針用無線通信機１０の本体とアンテナ２０とを一体として密封被覆しており、信号線３０貫通させる水蜜貫通孔３１が設けられており、信号線３０が防水カバー４０の外部に防水状態を保って引き出されている。
【０００８】
防水カバー３０の水道メータ検針用無線通信機１０の上部のアンテナ部分には浸水時にはアンテナ部分が水面上に浮上する浮力を持たせるための空間３１が設けてある。
防水カバー３０の内部に空間３１をもうけることにより、防水カバー３０で覆われた水道メータ検針用無線通信機１０の本体とアンテナ２０との重心Ｇは、防水カバー３０の下部に位置することになるので、これを水中に入れた場合には、常にアンテナ２０が水道メータ検針用無線通信機１０の本体の上部に来るような状態で浮上する。
このように構成された本発明の防水カバーを持った水道メータ検針用無線通信機は、従来の水道メータ検針用無線通信機と同様にメーターボックスＭＢの中に設置されるが、その設置方法は、水道メータ検針用無線通信機１０は何処にも固定されずにフリーの状態で設置され、水道メータＭＴと信号線３０を介して接続される。
無線検針システムによる検針作業は、例えば訪問検針作業では、検針者が検針を行なうメータＭＴの近隣まで近づいて、そのメータのアドレス（ＩＤ）番号をハンディターミナル３に設定した後、ハンディターミナル３に搭載されている無線機より、通信要求を出して指定されたアドレス（ＩＤ）番号のメータＭＴに接続される水道メータ検針用無線通信機１０を呼び出し、そのメータの積算値を無線でハンディターミナル３で読み取ることにより行われる。
【０００９】
図３は、本発明の防水カバーを持った水道メータ検針用無線通信機１０が設置されているメーターボックスＭＢが浸水した場合の状態を説明する図である。
図３において、図１，図２と同一の部分には同一の符合を付けてその説明を省略する。
本発明の水道メータ検針用無線通信機１０は、メーターボックスＭＢの中に設置される場合に、水道メータ検針用無線通信機１０はメーターボックスＭＢの何処にも固定されずにフリーの状態で設置され、水道メータＭＴと信号線３０を介して接続されている。
図３に示すように、本発明の防水カバーを持った水道メータ検針用無線通信機１０が設置されているメーターボックスＭＢが浸水した場合には、防水カバーの中のアンテナ１５の部分に設けられた空間２１の浮力により、防水カバーを持った水道メータ検針用無線通信機１０は、水面上に浮上し、そのアンテナ１５の部分が水面上に出る。
これにより、メーターボックスＭＢが浸水した場合にも、検針用のハンディターミナル３との通信が確保されるので、常に安定した検針業務を行うことが可能になる。
【００１０】
【発明の効果】
以上の説明より明らかなように、本発明の防水カバーを持った水道メータ検針用無線通信機は、水道の使用量を示す積算メータの値を、無線通信を利用して検針するようにした無線遠隔検針システムにおいて、水道メータ検針用無線通信機のアンテナ部分に浸水時にアンテナ部分が水面上に浮上する浮力を持った空間を設けて、水道メータ検針用無線通信機本体とアンテナを一体として防水カバーにより密封被覆して、雪解水や常時流されている融雪水、大雨等により積算メータの設置場所が浸水した場合には、水道メータ検針用無線通信機のアンテナ部分が水面上に浮上するようにして、通信が確保出来るようにして無線検針システムを安定して運用出来るようにしたものである。
このため、従来読取り作業が困難であった水道メータに本発明の防水カバーを持った水道メータ検針用無線通信機を適用することにより、水道メータの検針作業を容易に行うことができるようになると共に、降雪地帯では冬期間における検針作業そのものができず、月単位の正確なメータ値をとることができなかったなどの、地域的な困窮問題も殆ど解決できるようになる。これにより、公益事業が本来目指すところの公共の便益を新たな付加情報サービスとして提供できるようになるなど、あらたな産業の創造および産業の発展に寄与できる等の幅広い効果を得ることが出来る。

[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
【Example】
FIGS. 1 and 2 are perspective views of an outer case of a wireless communication device main body for explaining a configuration of a water meter reading wireless communication device having a waterproof cover according to the present invention.
The embodiment in FIG. 1 shows an example in which the main body of the wireless meter for water meter reading is square, and the embodiment in FIG. 2 shows an example in which the main body of the wireless meter for water meter reading is flat. It is shown.
1 and 2, reference numeral 10 denotes a wireless meter for water meter reading, and reference numeral 20 denotes an antenna of the wireless meter for water meter reading. Reference numeral 30 denotes a signal line connecting the water meter reading wireless communication device 10 and the water meter, and reference numeral 40 denotes a waterproof cover that integrally covers the water meter reading wireless communication device body and the antenna. The waterproof cover 40 integrally covers the main body of the water meter meter reading wireless communication device 10 and the antenna 20 in a hermetically sealed manner, and is provided with a water-penetrating through hole 31 through which the signal line 30 penetrates. It is pulled out while keeping it waterproof.
[0008]
A space 31 is provided in the antenna portion of the waterproof cover 30 above the water meter reading wireless communication device 10 so that the antenna portion has a buoyancy to float on the water surface when it is submerged.
By providing the space 31 inside the waterproof cover 30, the center of gravity G between the main body of the water meter meter reading wireless communication device 10 and the antenna 20 covered with the waterproof cover 30 is located below the waterproof cover 30. Therefore, when this is put in water, the antenna 20 always floats in a state where the antenna 20 comes to the upper part of the main body of the water meter reading wireless communication device 10.
The water meter reading wireless communication device having the waterproof cover of the present invention configured as described above is installed in the meter box MB in the same manner as the conventional water meter reading wireless communication device. The water meter reading wireless communication device 10 is installed in a free state without being fixed anywhere, and is connected to the water meter MT via a signal line 30.
In the meter reading operation by the wireless meter reading system, for example, in a visit meter reading operation, the meter reader approaches the vicinity of the meter MT that performs the meter reading, sets the address (ID) number of the meter on the handy terminal 3, and then mounts the meter on the handy terminal 3. A wireless communication device 10 issues a communication request, calls the water meter reading wireless communication device 10 connected to the meter MT of the specified address (ID) number, and wirelessly transmits the integrated value of the meter to the handy terminal 3. This is done by reading.
[0009]
FIG. 3 is a diagram illustrating a state where the meter box MB in which the water meter reading wireless communication device 10 having the waterproof cover of the present invention is installed is flooded.
In FIG. 3, the same portions as those in FIGS. 1 and 2 are denoted by the same reference numerals, and description thereof will be omitted.

Due to the buoyancy of the space 21, the water meter reading wireless communication device 10 having the waterproof cover floats on the water surface, and the antenna 15 portion comes out on the water surface.
Accordingly, even when the meter box MB is flooded, communication with the handy terminal 3 for meter reading is ensured, so that stable meter reading can be performed at all times.
[0010]
【The invention's effect】
As is clear from the above description, the wireless communication device for water meter reading having the waterproof cover according to the present invention is a wireless communication device that measures the value of the integrating meter indicating the amount of water used by using wireless communication. In the remote meter reading system, a water-proof cover is provided in which the antenna part of the water meter meter reading wireless communication device has a buoyant space in which the antenna part floats on the water surface when submerged in water, and the water meter meter reading wireless communication body and the antenna are integrated. When the location of the integrating meter is flooded by snowmelt, snowmelt that is constantly flowing, heavy rain, etc., the antenna part of the wireless meter for water meter reading will float above the water surface. Thus, the wireless metering system can be stably operated by ensuring communication.
For this reason, by applying the water meter meter reading wireless communication device having the waterproof cover of the present invention to a water meter which has conventionally been difficult to read, the meter reading operation of the water meter can be easily performed. At the same time, in the snowfall area, it is almost impossible to solve the regional distress, such as the inability to read the meter itself in the winter period and to obtain accurate monthly meter values. As a result, it is possible to obtain a wide range of effects such as being able to provide the public benefits originally intended by the public utility as a new additional information service and contributing to the creation and development of new industries.
