【0001】 [0001]

【発明の属する技術分野】本発明は、建屋内無電源電波中継器であり、特に、電波を遮蔽する床、壁、間仕切等を有する大きなビルディング内で、無線通信を行う際に、前記電波遮蔽物の存在に関係なく無線通信を可能にするための建屋内無線通信用電波中継器に関する。 BACKGROUND OF THE INVENTION The present invention is a building in a no-power radio repeater, in particular, the floor of shielding radio waves, the wall, in a large building with a partition or the like, when performing radio communication, the radio wave shielding about building a wireless communication radio wave relay for enabling wireless communication regardless of the existence of the object.

【0002】 [0002]

【従来の技術】近年、益々大形な建物が建てられ、その内部で多数の情報処理装置またはOA機器を相互に結合させ所謂システムにして使用する例が増えてきたが、これらの装置または機器よりなるシステムは、常に注意深く保守して、良好な稼働状態を保持させなければならない。 In recent years, it built increasingly large buildings, but examples have been increasing to be used in the number of the information processing apparatus or the called system plant is bound to each other OA equipment therein, these devices or equipment become more system, always carefully maintained, must be maintain good operating condition.

【0003】上記保守作業では、例えば、据付時の現場調整を始め、障害対策などの際、保守作業者が複数個所それぞれに居て相互に連絡を取りながら作業しなければならないことが多い。 [0003] In the above maintenance work, for example, started the site adjustment at the time of installation, when such as fault tolerance, it is often a maintenance worker must work while to contact each other to stay in each of a plurality of locations. そのような場合に、既設の建屋内の電話施設を利用できる場合もあるが、電話を設置してない個所もあるし、他の業務のために設置した電話を保守作業のために専用することは、たとえ一時的にせよ不可能な場合も多い。 In such a case, you can sometimes be using a telephone facility in the building of the existing, but to also point you have not set up a telephone, which only a phone call that was installed for other work for maintenance work It is, even if temporary in many cases impossible case. 従って、保守作業者は、不特定の複数個所の問で相互に連絡する必要があるから、それぞれ、専用の無線通信機によって連絡をとるようにすることが望ましい。 Therefore, the maintenance worker, it is necessary to contact each other in Question unspecified plurality of locations, respectively, it is desirable to keep in touch by a dedicated radios. 通常、この目的には、電波法上、簡易無線と分類され、例えば150MHz帯や450MHz帯で、地区ごとに、互いに送受する少数の固定、移動無線の組に対して、無線従事者の資格がなくても認可される代わりに、空中線電力や空中線高さ、その他、通話時間などに、電波を共同で効率的に利用するために種々の規制を受ける方式の無線通信機が適当と思われる。 Usually, for this purpose, on the Radio Law, it is classified as a simple radio, for example, 150MHz band and 450MHz band, for each district, a small number of fixed transmitting and receiving each other, the mobile radio set, qualify telegraphist instead of being authorized without, antenna power and aerial height, other, etc. call time, the wireless communication apparatus system that receives the various regulations in order to efficiently utilize the radio waves jointly deemed appropriate.

【0004】しかし、今日の建物の中にある鉄骨や鉄筋が埋め込まれたコンクリートの厚い床面や壁面は電波を殆ど通さないし、移設可能な仕切壁も、遮音などのために床から天井まで密閉している場合などは、材料として、通常、鋼板を用いているためもあって電波を遮蔽する。 [0004] However, the sealing thick floor and walls of steel and rebar is embedded concrete that is in today's buildings do not pass through the radio waves almost, relocatable partition wall also, from the floor, such as for sound insulation to the ceiling etc. If you are, as a material, usually, also a shielding radio waves due to the use of steel plate. 通常のガラス窓は比較的電波を良く通過させるので、本発明者等の実験の結果によれば、建屋の外部に面する部屋同士では、遠く離れた階の問でも、近くに隣接する建屋との間でも、無線交信可能であったが、建屋内部の壁面、金属製仕切壁などに囲まれた部屋の間では、 Since ordinary glass windows to relatively Telecommunications well passes, according to the results of experiments of the present inventors, in the room between facing outside of the building, even in distant floors question, buildings adjacent to near Metropolitan even among, but was possible wireless communication, between the building interior wall, surrounded by such a metal partition wall room
これらの電波遮蔽物によって、例えば50dB以上減衰し、簡易無線機では通信不能であった。 These wave shield, for example 50dB attenuated or, in the simple radio was unable to communicate. なお、用途から考えても判るように、高性能でも大きく重い無線装置は、このような目的には使用し難く、無線通信装置自体の性能改善では解決し難い。 Incidentally, as can be seen be considered from applications, high performance even massive wireless device, difficult to use for such a purpose, it is difficult to solve in the performance improvement of the wireless communication device itself.

【0005】これらを解決するために、電波を遮蔽する床、壁、間仕切等を有する建屋内で、電波遮蔽物に隔てられた両側の室内それぞれに、使用する無線通信用電波の送受に適したアンテナを前記電波遮蔽物を挾んで設置し、そして、これら両側のアンテナ間を、前記電波遮蔽物に穿設した、孔径が精々2cm程度の貫通孔に同軸ケーブルを通し、この同軸ケーブルの両端と両側のアンテナそれぞれの支持部とにコネクタを取付け、これらのコネクタを介して着脱自在に連結接続した建屋内無線通信用電波中継器を使用することが提案されている。 [0005] In order to solve these problems, the floor of shielding radio waves, the wall, in a building having a partition or the like, each room on both sides separated the radio wave shield, suitable for transmission and reception of radio waves for wireless communication using the antenna is placed across the electric wave shield, and, between these two sides of the antenna, and formed in the radio wave shield, through a coaxial cable pore size in the through-holes of about at most 2 cm, and both ends of the coaxial cable attaching the connector to the opposite sides of the antenna respective support portions, the use of building a wireless communication radio wave repeater detachably connected connected via these connectors have been proposed.

【0006】しかしながら、この建屋内無線通信用電波中継器では、アンテナ等について、詳細に検討されておらず、得られる特性は、十分なものではなかった。 However, in this building in the radio communication radio wave repeater, the antenna and the like, have not been studied in detail, the characteristics obtained are not sufficient. 特に、アンテナの保護や外観等について、考慮していなかった。 In particular, the antenna protection and appearance, etc., were not taken into account.

【0007】 [0007]

【発明が解決しようとする課題】本発明は、上記のような、相互に通信しようとする電波遮蔽物の両側のうち、 SUMMARY OF THE INVENTION It is an object of the present invention, as described above, of the both sides of the radio wave shield to be communicate with each other,
少なくとも一方の部屋が、そのままでは無線通信用電波を遮蔽して交信不能にするよう囲まれている場合であっても、当該電波遮蔽物を挾んで設置することにより、その電波遮蔽物に防げられずに無線通信を可能とし、そして、作り易く、廉価で、更に、簡単な構造で、アンテナを保護し、外観を良くした無指向性の建屋内無線通信用電波中継器を提供することを目的とする。 At least one of the room, even when it is being surrounded to the communication impossible to shield radio waves for wireless communication, by installing sandwiching the radio wave shielding object, are prevented in the radio wave shield and enabling wireless communication without, and made easy, inexpensive, further objects with a simple structure, to protect the antenna, to provide a nondirectional building a wireless communication radio wave repeater to improve the appearance to.
