【発明の属する技術分野】
本発明は、網制御装置と少なくとも1つの端末装置との間の情報のやりとりを、それぞれ網制御装置側および端末装置側に設けられた無線装置を介して無線により行なう電話回線利用端末システムに関する。
【0002】
【従来の技術】
例えば電気、ガス、水道等の自動検針システムにみられるように、複数の端末装置とセンタ装置との間の情報のやりとりを網制御装置を介して電話回線を用いて行なうシステムが提案されるに至っている。そして、このようなシステムにおいては、センタ装置による端末装置の監視効率の向上という観点から、1台の網制御装置に接続される端末装置の数が増大し、またこれに伴い端末装置の設置場所も網制御装置から離反する傾向にある。このため、網制御装置と端末装置との間の情報のやりとりを、両装置側に無線装置を配備して無線で行なうことが検討されるに至っている。
【0003】
ところで、近年の電話通信技術の発展に伴い、電話回線として、従来からのノーリンギング回線だけでなく、ISDN回線を用いることも可能な環境となっている。各回線においては、当然のことながら、伝送されるデータの種類が異なり、特に、ISDN回線においてはアナログ通信およびデジタル通信によっても異なる。このため、電話回線に接続され、電話回線の制御を行なう網制御装置についても、接続される電話回線の種類毎に異なるものとならざるを得ない。
【0004】
【発明が解決しようとする課題】
このように、電話回線の種類毎に網制御装置が異なることから、前述した如く網制御装置と端末装置との間を無線装置を介して行なおうとする場合、次のような問題がある。
【0005】
網制御装置とこの網制御装置側の無線装置(以下、適宜「無線装置親機」と呼ぶ)とを一個の筐体で構成した場合には、電話回線の変更に伴い、網制御装置の交換と共に無線装置親機をも交換しなければならず、非効率である。
【0006】
また、網制御装置と無線装置親機とを別個とした場合には、両装置を個別に設置した後、両装置間の配線工事をしなければならず、設置工事に手間がかかり、加えて設置場所のスペースを縮少することができない。
【0007】
本発明は、上記に鑑みてなされたもので、その目的としては、電話回線の変更に伴う網制御装置の交換を無線装置親機に影響を与えることなく容易に行なえると共に、網制御装置と無線装置親機の設置スペースの縮少に寄与し得る電話回線利用端末システムを提供することにある。
【0008】
【課題を解決するための手段】
上記目的を達成するため、請求項1記載の本発明は、電話回線の制御を行なう網制御装置と少なくとも1つの端末装置との間の情報のやりとりを、それぞれ網制御装置側および端末装置側に設けられた無線装置を介して無線により行なう電話回線利用端末システムにおいて、前記網制御装置および前記網制御装置側の無線装置に設けられ、互いに相手を結合・離脱させる結合・離脱手段と、この結合・離脱手段により前記網制御装置および無線装置が結合して一体化したときに、両装置間に信号路を形成する信号路形成手段とを有し、前記結合・離脱手段が、両装置の結合面に互いに嵌合可能に形成された凹凸構造の螺旋ねじからなるねじ込み機構であることを要旨とする。
【0009】
請求項1記載の発明では、網制御装置と無線装置を別体にて構成する一方、結合・離脱手段を設けて互いに結合して一体化可能としたことで、電話回線が変更されても網制御装置だけを新たに交換すればよい。
【0010】
請求項2記載の本発明は、電話回線の制御を行なう網制御装置と少なくとも1つの端末装置との間の情報のやりとりを、それぞれ網制御装置側および端末装置側に設けられた無線装置を介して無線により行なう電話回線利用端末システムにおいて、前記網制御装置および前記網制御装置側の無線装置に設けられ、互いに相手を結合・離脱させる結合・離脱手段と、この結合・離脱手段により前記網制御装置および無線装置が結合して一体化したときに、両装置間に信号路を形成する信号路形成手段とを有し、前記結合・離脱手段が、両装置の結合面に互いに嵌合可能に形成された凹凸構造であり、前記網制御装置または無線装置の一方に設けられ、前記網制御装置または無線装置の他方を収容固定し、さらに、前記網制御装置および無線装置を覆う蓋を有することを要旨とする。
【0013】
請求項2記載の発明においても、網制御装置と無線装置を別体にて構成する一方、互いに結合して一体化可能としたことで、電話回線が変更されても網制御装置だけを新たに交換すればよい。
【0014】
請求項記載の本発明は、請求項1または請求項2記載の発明において、前記信号路形成手段が、前記網制御装置および無線装置の結合面に設けられ、両装置が一体化したときに互いに接触する電極であることを要旨とする。
【0015】
請求項記載の本発明は、請求項1または請求項2記載の発明において、前記信号路形成手段が、前記網制御装置および無線装置が一体化したときに対向するように両装置の結合面に設けられた窓と、この窓を通して光による信号のやりとりを行なう両装置に設けられた光電変換部とを有することを要旨とする。
【0016】
請求項乃至記載の発明では、網制御装置および無線装置を結合して一体化することで、自動的に両装置間の信号路が形成される。
【0017】
【発明の実施の形態】
以下、図面を用いて、本発明の実施の形態を説明する。
【0018】
図1および図2は、本発明の第1の実施の形態に係る電話回線利用端末システムの構成を示す図である。その特徴としては、結合面を構成する一面に凸部1が形成された網制御装置3および結合面を構成する一面に凹部5が形成された無線装置親機7を別体として構成し、網制御装置3と無線装置親機7とをこの凸部1および凹部5を互いに嵌合してスライドさせることで一体化できるようにすると共に、一体化したときに網制御装置3と無線装置親機7との間で自動的に信号路が形成されるように、凸部1および凹部5の所定の位置にそれぞれ電極9および電極11を設けたことにある。ここで、凸部1および凹部5の嵌合スライド面には、傾斜をつけることが好ましい。なお、図1および図2において、13は電話回線(図示せず)が接続されるモジュラジャック、15は電話機(図示せず)が接続されるモジュラジャックである。また、電極9および電極11は、それぞれ網制御装置3および無線装置親機7のインタフェース回路17,19に接続されている。
【0019】
図3は、網制御装置3と無線装置親機7を一体化した状態でのデータ伝送時の回路状態を示すもので、(a)は網制御装置3から無線装置親機7へのデータ伝送時、(b)はその逆の時を示している。すなわち、(a)の状態においては、網制御装置3の第1のフォトカプラ21のダイオード21aが電話回線側からのデータによってオン−オフすると、これにより第1のフォトカプラ21のフォトトランジスタ21bもオン−オフし、このオン−オフに応じて無線装置親機7の受信入力信号はグランドレベルとVC レベルに変化する。すなわち、オンの時には、グランドレベルになり、オフの時には、VC レベルになる。一方、(b)の状態においては、無線装置親機7の第2のスイッチ23がa接点側に接続されて接地され、第1のスイッチ25がオン−オフすることにより、網制御装置3の第2のフォトカプラ27のダイオード27aに電流I1が流れ、これにより第2のフォトカプラ27のフォトトランジスタ27bがオン−オフする。この結果、無線装置親機7の第1のスイッチ25がb接点側に接続されてVC レベルとなった場合には、第2のフォトカプラ27のフォトトランジスタ27bのコレクタからの受信入力信号がグランドレベルになり、また第1のスイッチ25がa接点側に接続されてグランドレベルになった場合には、第2のフォトカプラ27のフォトトランジスタ27bのコレクタからの受信入力信号がVD レベルになる。
【0020】
したがって、本実施の形態によれば、網制御装置に接続されている電話回線の変更があった場合には、網制御装置のみを新たな電話回線に対応する網制御装置に交換すればよく、無線装置親機に何ら影響を与えることがない。また、網制御装置と無線装置親機を一体化するだけで両者間において信号路が形成されるので、両装置間での配線を別個行なう必要がなく、設置工事の手間を省き、さらに設置スペースの縮少化を図ることができる。
【0021】
なお、上記実施の形態では、凸部1を網制御装置3に、凹部5を無線装置親機7にそれぞれ形成したが、逆でも構わない。
【0022】
また、上記実施の形態では、電極9を凸部1と同一面内に、電極11を凹部5と同一面内にそれぞれ設けたが、網制御装置3および無線装置親機7における結合面のどこかであればよい。
【0023】
図4乃至図6は、本発明の第2の実施の形態に係る電話回線利用端末システムの構成を示す図である。その特徴としては、結合面を構成する一面に外周囲がねじ部30となっている凸部31が形成された網制御装置33および結合面を構成する一面に内周囲がねじ部34となっている凹部35が形成された無線装置親機37を別体として構成し、網制御装置33と無線装置親機37とをこの凸部31および凹部35のねじ部30,34において互いに嵌合してねじ込むことで一体化できるようにすると共に、一体化したときに網制御装置33と無線装置親機37との間で自動的に信号路が形成されるように、凸部31および凹部35の所定の位置にそれぞれ電極9および電極11を設けたことにある。なお、図4乃至図6において、図1乃至図3と同一構成には同一の符号を示す。
【0024】
したがって、本実施の形態においても、前記第1の実施の形態と同様の効果を奏することができる。
【0025】
図7および図8は、本発明の第3の実施の形態に係る電話回線利用端末システムの構成を示す図である。その特徴としては、網制御装置41に別体で構成した無線装置親機43を収容固定する空間45を設けることで一体化できるようにすると共に、一体化したときに網制御装置41と無線装置親機43との間で自動的に信号路が形成されるように、両者所定の位置にそれぞれ電極9および電極11を設けたことにある。なお、図7および図8には、特に図示していないが、空間45には、無線装置親機43を規定の位置に誘導し固定するための手段が設けられている。また、図7および図8において、47はスライド式の蓋であり、さらに図1乃至図3と同一構成には同一の符号を示す。
【0026】
したがって、本実施の形態においても、前記第1の実施の形態と同様の効果を奏することができる。
【0027】
なお、上記実施の形態においては、網制御装置41に空間45を設けたが、無線装置親機に空間を設けて網制御装置を収容固定するようにしてもよいことは言うまでもない。
【0028】
一方、上述した各実施の形態においては、一体化したときの網制御装置と無線装置親機との間の信号路を電極9,11によって形成するようにしたが、図9に示す如く、この電極9,11に代って窓51,53を設け、この窓を通した光による信号路としてもよい。すなわち、図9の構成例では、網制御装置のインタフェース回路17の入出力段には窓51近傍にフォトダイオード55およびフォトトランジスタ57がそれぞれ設けられ、また無線装置親機のインタフェース回路19の入出力段には窓53近傍にフォトトランジスタ57に対向してフォトダイオード59およびフォトダイオード55に対向してフォトトランジスタ61がそれぞれ設けられている。そして、網制御装置のインタフェース回路17より送信される情報は、フォトダイオード55より出力され、窓51,53を介してフォトトランジスタ61に入力され、無線装置親機のインタフェース回路19で受信される。また、無線装置親機のインタフェース回路19より送信される情報は、フォトダイオード59より出力され、窓51,53を介してフォトトランジスタ57に入力され、網制御装置のインタフェース回路17にて受信されるのである。
【0029】
したがって、このような光による信号路を形成することで、絶縁性および高耐雷性を向上することができる。
【0030】
なお、図9において、63および65は、それぞれ窓51および53に設けられ、窓51および53の開口を覆う透明体である。
【0031】
【発明の効果】
以上、説明したように、請求項乃至記載の発明によれば、網制御装置と無線装置親機を別体にて構成する一方、互いに結合して一体化可能としたことで、電話回線が変更されても網制御装置だけを新たに交換すればよいので、電話回線の変更に伴う網制御装置の交換を無線装置親機に何ら影響を与えることなく容易に行なうことができる。
【0032】
また、請求項乃至記載の発明によれば、網制御装置および無線装置親機を結合して一体化することで、自動的に両装置間の信号路が形成されるので、網制御装置と無線装置親機の設置作業を簡単化でき、また設置スペースを従来に比べて縮小することができる。

【The invention's effect】
As described above, according to the first and second aspects of the present invention, the network control device and the wireless device base unit are configured separately, and can be combined and integrated with each other. Even if the network is changed, only the network control device needs to be exchanged. Therefore, the network control device can be easily exchanged with the change of the telephone line without any influence on the wireless device base unit.
[0032]
According to the third to fourth aspects of the present invention, since the network control device and the wireless device base unit are combined and integrated, a signal path between the two devices is automatically formed. The installation work of the wireless device master can be simplified, and the installation space can be reduced compared to the conventional one.
