本実施形態の無線通信ガスメータ1は、例えば都市ガス等のガスの使用量を測定するとともに使用量についての情報を送受信するものであって、図1、2に示すように、ガスメータ2と、ガスメータ用無線機3と、を備える。 The wireless communication gas meter 1 of the present embodiment measures the amount of gas used, for example, city gas, and transmits / receives information about the amount of gas used. As shown in FIGS. 1 and 2, the gas meter 2 and the gas meter 1 are used. The radio device 3 is provided.

ガスメータ2は、全体が箱状に形成され、幅方向の両側において上方に向かって突出した一対のガス管接続口21と、正面に設けられた流量表示部22と、流量表示部22の下方に形成された凹状の端子収容部23と、端子収容部23内に収容された通信端子部24と、端子収容部23の外側に形成された枠状のカバー取付部25と、を有する。 The gas meter 2 is formed in a box shape as a whole, and has a pair of gas pipe connection ports 21 protruding upward on both sides in the width direction, a flow rate display unit 22 provided on the front surface, and a flow rate display unit 22 below the flow rate display unit 22.

The cover portion 31 has a recess 311 for accommodating the radio equipment main body 32, and is formed in a box shape with one side open. Further, the cover portion 31 is attached to the cover attachment portion 25 of the gas meter 2 so as to cover the communication terminal portion 24 in the terminal accommodating portion 23. At this time, the cover portion 31 may be attached by a fixing member such as a screw. Further, the cover portion 31 may be made of an appropriate metal, resin member or the like so that the outer surface thereof has the same appearance (color, gloss, texture, etc.) as the outer surface of the gas meter 2. Further, appropriate coating may be applied so that the outer surface of the cover portion 31 has the same appearance as the outer surface of the gas meter 2.

無線機本体32は、通信端子部24に接続された接続配線4の他端が接続されることで、ガスメータ2から情報を受信する。無線機本体32は、図3に示すように、信号を送受信するための逆Fアンテナ321と、送信する電波を変調および増幅する送信部322Aおよび受信した電波を増幅および復調する受信部322Bからなる無線部322と、無線部322を制御する制御部323と、各種のプログラムや設定値等を記憶する記憶部324と、ガスメータ2と通信するための通信インターフェイス325と、を有する。 The radio main body 32 receives information from the gas meter 2 by connecting the other end of the connection wiring 4 connected to the communication terminal portion 24. As shown in FIG. 3, the radio main body 32 includes an inverted F antenna 321 for transmitting and receiving signals, a transmitting unit 322A that modulates and amplifies the transmitted radio wave, and a receiving unit 322B that amplifies and demodulates the received radio wave.

ここで、以上のようなガスメータ用無線機3が設けられる無線自動検針システム100について、図4に基づいて説明する。各需要家によって使用される複数のガスメータ用無線機が、多段中継無線200によって互いに接続される。このように接続される複数のガスメータ用無線機には、ガスメータ用無線機3と同様のガスメータ用無線機20に加え、少なくとも1つのゲートウェイ無線機30が含まれる。即ち、ガスメータ用無線機3の無線機本体32は、他のガスメータ用無線機を外部機器として通信する。尚、ガスメータ用無線機3がゲートウェイ無線機であってもよい。 Here, the wireless automatic meter reading system 100 provided with the gas meter radio 3 as described above will be described with reference to FIG. A plurality of gas meter radios used by each consumer are connected to each other by a multi-stage relay radio 200. The plurality of gas meter radios connected in this way include at least one gateway radio 30 in addition to the gas meter radio 20 similar to the gas meter radio 3. That is, the radio main body 32 of the gas meter radio 3 communicates with another gas meter radio as an external device. The gas meter radio 3 may be a gateway radio.

ゲートウェイ無線機30は、多段中継無線200によって他のガスメータ用無線機と通信するだけでなく、広域無線機30Aを有しており、広域通信回線300を介し、広域無線機40Aを有するセンター40と通信する。以上のように、センター40がゲートウェイ無線機30と通信するとともに、ゲートウェイ無線機30を介して他のガスメータ用無線機と通信可能な無線自動検針システム100が構成される。 The gateway radio 30 not only communicates with other gas meter radios by the multi-stage relay radio 200, but also has a wide area radio 30A, and communicates with the center 40 having the wide area radio 40A via the wide area communication line 300. connect. As described above, the wireless automatic meter reading system 100 is configured in which the center 40 can communicate with the gateway radio 30 and also communicate with other gas meter radios via the gateway radio 30.

このような無線自動検針システム100では、センター40が各需要家におけるガスの使用量についての情報を要求することにより、各ガスメータ用無線機からガス使用量に関する情報が信号として送信される。また、無線自動検針システム100においては、各需要家のガスメータ用無線機が無線通信のみで結ばれており、通信のための配線作業が極めて容易となる。 In such a wireless automatic meter reading system 100, when the center 40 requests information on the amount of gas used by each consumer, the information on the amount of gas used is transmitted as a signal from each gas meter radio. Further, in the wireless automatic meter reading system 100, the gas meter radios of each consumer are connected only by wireless communication, and the wiring work for communication becomes extremely easy.

以下、ガスメータ用無線機3の放射電磁波の指向性及び強度についての実験結果の一例を図5、6及び表1に示す。尚、図5はガスメータ用無線機3をガスメータ2に取り付けない状態(無線機単体)に対応し、図6はガスメータ2に取り付けた状態(メータ一体)に対応する。また、本実験では、電波暗室内においてガスメータ用無線機3から放射される電波をダイポール受信アンテナで受信した際の最大電波強度MAX(dBm)、最小電波強度MIN(dBm)および平均電波強度AVE(dBm)を測定した。このとき、水平偏波及び垂直偏波を独立に評価するために、それぞれに対応したダイポールアンテナを独立に設置した。 Hereinafter, examples of experimental results on the directivity and intensity of the radiated electromagnetic wave of the gas meter radio 3 are shown in FIGS. 5 and 6 and Table 1. Note that FIG. 5 corresponds to a state in which the gas meter radio 3 is not attached to the gas meter 2 (radio unit alone), and FIG. 6 corresponds to a state in which the gas meter 2 is attached (integrated with the meter). Further, in this experiment, the maximum radio wave strength MAX (dBm), the minimum radio wave strength MIN (dBm), and the average radio wave strength AVE (dBm) when the radio wave radiated from the gas meter radio 3 is received by the dipole receiving antenna in the anechoic chamber. dBm) was measured. At this time, in order to evaluate the horizontally polarized waves and the vertically polarized waves independently, the corresponding dipole antennas were independently installed.

Figure 0006966186

本実験例では、放射電磁波の指向性を示すMAX/MIN(1に近いほど指向性が良い)は、ガスメータ用無線機3をガスメータ2に取り付けても、一部を除きほとんど劣化しなかった。また、放射電磁波の強度を示す平均電波強度AVE(大きいほど強度が高い)は、ガスメータ用無線機3をガスメータ2に取り付けても、大きな低下は見られなかった。即ち、本実験例ではメータ一体としても(即ち、図1に示すようにガスメータ用無線機3をガスメータ2に取り付けても)ガスメータ用無線機3の放射電磁波の指向性及び強度は良好であった。 In this experimental example, MAX / MIN (the closer it is to 1, the better the directivity), which indicates the directivity of the radiated electromagnetic wave, hardly deteriorates except for a part even when the gas meter radio 3 is attached to the gas meter 2. Further, the average radio wave intensity AVE (the larger the intensity, the higher the intensity), which indicates the intensity of the radiated electromagnetic wave, did not decrease significantly even when the gas meter radio 3 was attached to the gas meter 2. That is, in this experimental example, the directivity and intensity of the radiated electromagnetic wave of the gas meter radio 3 were good even when the meter was integrated (that is, even if the gas meter radio 3 was attached to the gas meter 2 as shown in FIG. 1). ..

しかしながら、無線通信ガスメータ1の設置環境によっては、放射電磁波の指向性及び強度が影響を受けることがあり、また、設置後の環境変化によっても影響を受けることがある。これにより、ガスメータ用無線機3の多段中継無線200における通信状態が良好でなくなってしまうことがある。 However, depending on the installation environment of the wireless communication gas meter 1, the directivity and intensity of the radiated electromagnetic wave may be affected, and may also be affected by changes in the environment after installation. As a result, the communication state of the multi-stage relay radio 200 of the gas meter radio 3 may not be good.

このような場合には、図7、8に示すように、無線通信ガスメータ1を、取付部材5および接続ケーブル6をさらに備えるものとすればよい。即ち、取付部材5によって、ガスメータ用無線機3をガスメータ2から離れた位置に設置すればよい。 In such a case, as shown in FIGS. 7 and 8, the wireless communication gas meter 1 may further include a mounting member 5 and a connecting cable 6. That is, the gas meter radio 3 may be installed at a position away from the gas meter 2 by the mounting member 5.

取付部材5は、板状のベース部51と、ベース部51の周縁から立設された枠部52と、枠部52の外側に形成された取付部53と、を有し、ガスメータ用無線機3を保持するとともにガスメータ以外の適宜な取付対象に取り付け可能に構成されている。 The mounting member 5 includes a plate-shaped base portion 51, a frame portion 52 erected from the peripheral edge of the base portion 51, and a mounting portion 53 formed on the outside of the frame portion 52, and is a radio device for a gas meter. 3 is held and can be attached to an appropriate attachment target other than the gas meter.

ベース部51と枠部52とによって、無線機本体32を収容可能な凹部54が形成される。枠部52は、ガスメータ2のカバー取付部25と同様の形状を有しており、ガスメータ用無線機3のカバー部31が取り付けられるようになっている。即ち、図8に示すように枠部52にカバー部31が取り付けられることにより、取付部材5とカバー部31との間に形成される空間に無線機本体32が収容される。 The base portion 51 and the frame portion 52 form a recess 54 capable of accommodating the radio equipment main body 32. The frame portion 52 has the same shape as the cover mounting portion 25 of the gas meter 2, and the cover portion 31 of the gas meter radio 3 can be mounted. That is, as shown in FIG. 8, the cover portion 31 is attached to the frame portion 52, so that the radio device main body 32 is accommodated in the space formed between the attachment member 5 and the cover portion 31.

このように収容される無線機本体32は、接続ケーブル6によって通信端子部24と接続される。接続ケーブル6は、ガスメータ2に対してガスメータ用無線機3を適宜な距離だけ離れた位置に設置することができるような長さを有して配索可能なものであればよい。枠部52には、接続ケーブル6が挿通される挿通孔521が形成されており、凹部54内で接続ケーブル6が無線機本体32に接続される。 The radio main body 32 accommodated in this way is connected to the communication terminal portion 24 by the connection cable 6. The connection cable 6 may be long enough to allow the gas meter radio 3 to be installed at an appropriate distance from the gas meter 2 and can be routed. An insertion hole 521 through which the connection cable 6 is inserted is formed in the frame portion 52, and the connection cable 6 is connected to the radio device main body 32 in the recess 54.

取付部53には、ビス等の固着部材が挿通される挿通孔531が形成され、例えば建物の内壁等を取付対象として取り付けられる。取付対象となる内壁の位置は、多段中継無線200におけるガスメータ用無線機3の通信状態が良好となる位置であればよく、周囲の設置物によって判断してもよいし、仮設置して通信状態を確認した後、適切な位置に本設置してもよい。 An insertion hole 531 through which a fixing member such as a screw is inserted is formed in the attachment portion 53, and for example, an inner wall of a building or the like is attached as an attachment target. The position of the inner wall to be mounted may be any position as long as the communication state of the gas meter radio 3 in the multi-stage relay radio 200 is good, and may be determined by surrounding installation objects, or may be temporarily installed and communicated. After confirming, the main installation may be performed at an appropriate position.

このような本実施形態によれば、以下のような効果がある。即ち、カバー部31に無線機本体32が内蔵されていることで、ガスメータ用無線機3全体を、通信端子部24を覆うカバーとして取り付けることができる。これにより、ガスメータ2にガスメータ用無線機3を取り付けることによる意匠性の低下を抑制することができ、無線通信ガスメータ1全体の意匠性の低下を抑制することができる。 According to this embodiment, there are the following effects. That is, since the radio main body 32 is built in the cover portion 31, the entire gas meter radio 3 can be attached as a cover that covers the communication terminal portion 24. As a result, it is possible to suppress the deterioration of the design due to the attachment of the gas meter radio 3 to the gas meter 2, and it is possible to suppress the deterioration of the design of the entire wireless communication gas meter 1.

また、ガスメータ用無線機3を保持した取付部材5を適宜な取付対象に取り付けることにより、ガスメータ用無線機3をガスメータ2から離れた場所にも設置することができ、通信状態を良好なものとすることができる。 Further, by attaching the mounting member 5 holding the gas meter radio 3 to an appropriate mounting target, the gas meter radio 3 can be installed at a place away from the gas meter 2, and the communication state is good. can do.

なお、本発明は、前記実施形態に限定されるものではなく、本発明の目的が達成できる他の構成等を含み、以下に示すような変形等も本発明に含まれる。 The present invention is not limited to the above-described embodiment, but includes other configurations and the like that can achieve the object of the present invention, and the following modifications and the like are also included in the present invention.

例えば、前記実施形態では、ガスメータ用無線機3の無線機本体32が外部機器として他のガスメータ用無線機と通信可能に構成されているものとしたが、無線機本体は、多段中継無線を介さずに、外部機器としてのセンターと直接通信するものであってもよい。 For example, in the above embodiment, the radio body 32 of the gas meter radio 3 is configured to be able to communicate with another gas meter radio as an external device, but the radio body is via a multi-stage relay radio.
