Description

この発明は、例えば屋内で地上デジタル放送波を中継するために用いられる地上デジタル放送のホームギャップフィラー装置を構成するホームギャップフィラー用再送信アンテナに関する。   The present invention relates to a home gap filler retransmission antenna that constitutes a home gap filler device for digital terrestrial broadcasting used, for example, to relay terrestrial digital broadcasting waves indoors.

次世代のデジタル放送システムとして、現在の地上波によるテレビジョン帯域を利用した地上デジタル放送の開発が進められている。この地上デジタル放送システムでは、放送サービスエリアの拡大及び難視聴地域の解消を目的として、ギャップフィラー対策の実施が検討されている。
このギャップフィラー対策では、放送波が届かないエリアごとにギャップフィラーと呼ばれる中継装置を設置するようにしている(例えば特許文献1及び特許文献2)。
As a next-generation digital broadcasting system, development of digital terrestrial broadcasting using the current television band based on terrestrial waves is underway. In this terrestrial digital broadcasting system, implementation of gap filler countermeasures is being studied for the purpose of expanding the broadcasting service area and eliminating difficult viewing areas.
In this gap filler countermeasure, a relay device called a gap filler is installed for each area where broadcast waves do not reach (for example, Patent Document 1 and Patent Document 2).

ところで、上記地上デジタル放送システムでは、アナログ放送システムにもあるように、テレビジョン受信機の室内用受信アンテナでデジタル放送波を受信できるものも要望されている。このような放送システムにあっても、放送サービスエリア以外に屋内における難視聴域の解消を目的としたギャップフィラー対策の実施も検討されることになる。
そこで、屋内において、受信場所に制限を受けることなく地上デジタル放送波を既知の屋内用受信アンテナを備えた放送受信機に受信させるための地上デジタル放送のホームギャップフィラー装置が提案されている。
特開2002−101032公報 特開2003−78492公報。
By the way, in the terrestrial digital broadcasting system, as in the analog broadcasting system, there is a demand for a digital broadcasting wave that can be received by the indoor receiving antenna of the television receiver. Even in such a broadcasting system, implementation of measures against gap filler for the purpose of eliminating the difficult viewing area indoors in addition to the broadcasting service area will be considered.
Therefore, there has been proposed a home gap filler device for digital terrestrial broadcasting for allowing a terrestrial digital broadcast wave to be received indoors by a broadcast receiver having a known indoor reception antenna without being limited by the reception location.

上記ホームギャップフィラー装置は、簡易な構成であるため、安価であるという利点がある。しかしながら、このホームギャップフィラー装置が普及してくると、狭い家屋内にも設置できるようにしたものも求められることになり、この場合、設置スペースも考慮しなければならない。   Since the above-mentioned home gap filler device has a simple configuration, there is an advantage that it is inexpensive. However, when this home gap filler device becomes widespread, a device that can be installed in a narrow house will be required, and in this case, the installation space must be taken into consideration.

この設置スペース対策としては、天井裏などに設置することも考えられるが、その場合アンテナの設置・保守を行う専門家が必要となるためコストがかかり、さらに天井の部材に導電性物質が入っていた場合に、室内への電波の照射が阻害される恐れがあるという問題点を有している。   As a countermeasure for this installation space, it may be possible to install it on the back of the ceiling, but in that case it requires a specialist to install and maintain the antenna, and it is costly, and there is a conductive material in the ceiling member. In this case, there is a problem that the irradiation of radio waves into the room may be hindered.

そこでこの発明の目的は、家屋内に設置する再送信アンテナとして設置スペースを別に確保する必要が無く、かつ安価で設置・保守が容易であり、かつ屋内で安定な受信環境を実現するためのホームギャップフィラー用再送信アンテナを提供することにある。   SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a home for realizing a stable reception environment that does not require a separate installation space as a re-transmission antenna installed in a house, is inexpensive and easy to install and maintain, and is indoors. It is to provide a retransmission antenna for a gap filler.

この発明は、上記目的を達成するために、以下のように構成される。
地上デジタル放送波を、放送受信機に設置される既知の屋内用受信アンテナで受信させるために使用され、屋外に設置される受信手段により前記地上デジタル放送波を受信し、信号増幅手段にてその受信信号を増幅して同一周波数の再送信号を生成し、この再送信号を送信手段により前記屋内用受信アンテナへ向けて再送信するホームギャップフィラー装置で前記送信手段として使用されるホームギャップフィラー用再送信アンテナであって、屋内に設置される既知の照明器具の紐状スイッチの紐に導電性物質を取り付けることにより、線状アンテナ素子を構成し、この線状アンテナ素子への給電方式として照明器具の天井取り付け板をアースとして不平衡給電するようにしたものである。
In order to achieve the above object, the present invention is configured as follows.
It is used to receive terrestrial digital broadcast waves with a known indoor receiving antenna installed in a broadcast receiver. The terrestrial digital broadcast waves are received by receiving means installed outdoors, and the signal amplifying means receives the terrestrial digital broadcast waves. The received signal is amplified to generate a retransmission signal of the same frequency, and this retransmission signal is retransmitted by the transmission means toward the indoor reception antenna. A linear antenna element is constructed by attaching a conductive substance to a string of a string-like switch of a known lighting fixture installed indoors, and the lighting fixture is used as a feeding method for the linear antenna element. The ceiling mounting plate is used as a ground for unbalanced power feeding.

この構成によれば、照明器具のカバー以外に、蛍光灯などの紐状スイッチの紐部分を線状アンテナとして利用し、照明器具取り付け板をアースとして不平衡給電を行うことにより容易に設置が可能で、さらに省スペース化を図ることが可能となる。   According to this configuration, in addition to the cover of the lighting fixture, it can be easily installed by using the string portion of the string-like switch such as a fluorescent lamp as a linear antenna and using the lighting fixture mounting plate as the ground for unbalanced power feeding. Thus, further space saving can be achieved.

以上詳述したようにこの発明によれば、家屋内に設置する再送信アンテナとして設置スペースを別に確保する必要が無く、かつ安価で設置・保守が容易であり、しかも屋内で安定な受信環境を実現するためのホームギャップフィラー用再送信アンテナを提供することができる。   As described above in detail, according to the present invention, it is not necessary to secure a separate installation space as a re-transmission antenna to be installed in a house, is inexpensive and easy to install and maintain, and provides a stable reception environment indoors. A retransmission antenna for a home gap filler can be provided.

以下、この発明の実施形態について図面を参照して詳細に説明する。
図1は、この発明に係るホームギャップフィラー装置の構成を示すブロック図である。
図1において、送信所から到来する地上デジタル放送波は、屋外に取り付けられた受信アンテナ11によって受信され、その受信信号がフィーダー12を介して増幅器13に供給される。増幅器13は、入力された受信信号を所定の振幅レベルまで増幅し、この増幅した信号を再送信号として屋内に設置される再送信アンテナ14に出力する。すると、再送信アンテナ14は、入力された再送信号を再送信波として屋内に放射する。
そして、屋内に設置されたテレビジョン受像機21では、既知の簡易受信アンテナ22で再送信波を受信し、その放送コンテンツを再生表示する。
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram showing a configuration of a home gap filler device according to the present invention.
In FIG. 1, a terrestrial digital broadcast wave arriving from a transmitting station is received by a receiving antenna 11 attached outdoors, and the received signal is supplied to an amplifier 13 via a feeder 12. The amplifier 13 amplifies the input received signal to a predetermined amplitude level, and outputs the amplified signal to the retransmission antenna 14 installed indoors as a retransmission signal. Then, the retransmission antenna 14 radiates the input retransmission signal indoors as a retransmission wave.
Then, the television receiver 21 installed indoors receives the retransmitted wave with a known simple receiving antenna 22 and reproduces and displays the broadcast content.

図2は、第1の実施形態に係わるホームギャップフィラー装置用の再送信アンテナの構成を示す図である。
(First embodiment)
The first embodiment of the present invention relates to a retransmission antenna 14 for a home gap filler device.
FIG. 2 is a diagram illustrating a configuration of a retransmission antenna for the home gap filler device according to the first embodiment.

符号31は一般家庭で使用されるカバーつきの円形蛍光灯(サークライン)32のカバーである。   Reference numeral 31 denotes a cover of a circular fluorescent lamp (circular line) 32 with a cover used in a general home.

すなわち、この第1の実施形態では、アンテナ形式として不平衡型モノポールアンテナ方式とし、スリーブ状の導電性材料から成る放射素子51を図2(a)に示すように円形蛍光灯32のスイッチ紐34に取り付けるようにしている。この放射素子51への給電は図2(b)に示すように平衡/不平衡変換回路52の出力のグランドを反射板43に接続し、信号給電側を放射素子51に不平衡給電部53を介して接続することで実現される。不平衡給電部53は余長を持たせてスイッチのオンオフ時の動きを吸収するようにする。
また、放射素子51は、天井取り付け部33を介して増幅器13に接続されている。
That is, in the first embodiment, the antenna type is an unbalanced monopole antenna system, and the radiating element 51 made of a sleeve-like conductive material is connected to the switch string of the circular fluorescent lamp 32 as shown in FIG. 34 is attached. As shown in FIG. 2B, the radiating element 51 is fed by connecting the ground of the output of the balanced / unbalanced conversion circuit 52 to the reflector 43, and the signal feeding side is connected to the radiating element 51 and the unbalanced feeding portion 53 is provided. This is realized by connecting through the network. The unbalanced power supply unit 53 has a surplus length so as to absorb the movement when the switch is turned on and off.
The radiating element 51 is connected to the amplifier 13 via the ceiling mounting portion 33.

なお、再送信号が不平衡給電される場合は、平衡/不平衡変換回路52の代わりにアンテナ整合回路を置くことで同様の効果が発揮される。   When the retransmission signal is fed unbalanced, the same effect can be achieved by placing an antenna matching circuit instead of the balanced / unbalanced conversion circuit 52.

このように第1の実施形態であれば、円形蛍光灯32のカバー31以外に、スイッチ紐34に放射素子51を取り付け、反射板43をアースとして不平衡給電を行うことにより再送信アンテナ14の設置が容易となり、さらに省スペース化を図ることが可能となる。また、円形蛍光灯32の交換に全く影響を与えることなく、さらに、照明器具本体の交換時にも不平衡給電部53を一時取り外し、器具交換後再度接続すれば良いだけで保守・交換作業に熟練は不要である。   As described above, according to the first embodiment, in addition to the cover 31 of the circular fluorescent lamp 32, the radiating element 51 is attached to the switch string 34, and the reflector 43 is grounded to perform unbalanced power feeding. Installation becomes easy and further space saving can be achieved. In addition, there is no influence on the replacement of the circular fluorescent lamp 32. Furthermore, when the luminaire is replaced, the unbalanced power feeding portion 53 is temporarily removed, and it is only necessary to reconnect after replacing the luminaire. Is unnecessary.

(その他の実施形態)
なお、この発明は上記実施形態に限定されるものではない。前記実施形態では、導電性物質の反射板を天井および壁面に貼りつけ、アンテナの反射板を構成する例を示したが、天井や壁に導電性物質を含む断熱材などが取り付けられている場合は、それをアンテナの反射板として利用できる。
その他、再送信アンテナの種類及び構成、簡易受信アンテナの種類及び構成、給電線路の種類等についても、この発明の要旨を逸脱しない範囲で種々変形して実施できる。
