Description
本考案は地下に埋設された上水道管、下水道管、ガス管、電気、通信ケーブルなどの保守情報を検知するマンホール内の検知機器と地上の監視機器とをマンホール蓋を介して無線通信を行う際に利用される鋳鉄製マンホールの蓋に設置する送受信用アンテナに関するものである。 The present invention is used for wireless communication between a detection device in a manhole that detects maintenance information such as a water pipe, a sewer pipe, a gas pipe, electricity, and a communication cable buried underground and a monitoring device on the ground via a manhole cover. It is related with the antenna for transmission / reception installed in the lid | cover of the cast iron manhole utilized for.
車道や歩道や花壇などの地下には人が生活するために埋設された上水道管、下水道管、ガス管、通信ケーブルなどの管理をするために、監視員が地上から出入りできる様な大きなマンホール（穴）から腕が出入りできる程度の小さなマンホールまで様々な大きさのマンホールが設けられ、さらに該マンホール内には上水道管の漏水、下水道の通水漏れ、ガス管のガス漏れ、通信ケーブルの断線など異常状態の情報を検知する無線機の検知機器を設置し、該検知情報を送受信するマンホール用アンテナを介して監視する無線機の監視機器を地上に設置して構成される無線通信用システムが設けられている。マンホール内の検知機器と地上の監視機器との間には様々な構造の技術が開発され、例えば特開平９−２６１５８号公報は「地下の無線機と地上局との間の無線通信の電波通路において、マンホール蓋と導電性の該蓋受け部との間に絶縁部材を介して、マンホール蓋を支持する無線通信用マンホール蓋」、特開平１１−６６４８４号公報は「地導体部及び給電線を有するアンテナをマンホール用の蓋に取り付けたアンテナ装置において、マンホールの一部の表面に設けた凹部に貫通孔を設けたマンホール用の蓋と、該貫通孔を通る給電線を接続しかつ前記した凹部に設置する平板基板アンテナからなるマンホール蓋」、実用新案登録第３０６１７１５号は「マンホールに設置されて各種のセンサーから測定値を入力する計測ユニットと、該計測ユニットに接続しかつマンホール蓋の穴内から電磁波を放射するアンテナを有して電磁波に変調する通信ユニットからなる現場情報処理装置、通信ユニットさらに測定値を受信する管理コンピュータの中央処理装置からなるマンホールの遠隔監視装置」などがある。またマンホール内で検知された情報を地上の監視機器（中央処理装置）に送受信するアンテナについても、例えば特開平５−２２７０７３号公報の「マンホール蓋の一部である誘導体に埋め込まれたダイポールアンテナ」や特開２００３−１４２９０９号公報の「マンホール蓋に形成された凹部にアンテナを収納し、その上部を誘電体製カバーで覆いかつマンホール蓋の表面側から該蓋と誘電体製カバーとを固定したマンホールアンテナ」など、各種の形状や構造で取り付けられている。 Large manholes that allow observers to enter and exit from the ground to manage water pipes, sewer pipes, gas pipes, communication cables, etc. that are buried in the basement of roadways, sidewalks, and flower beds. There are manholes of various sizes ranging from holes) to small manholes that allow arms to enter and exit. In addition, water leaks in water supply pipes, water leaks in sewers, gas leaks in gas pipes, disconnection of communication cables, etc. A wireless communication system configured by installing a wireless device for detecting abnormal state information and installing a wireless device for monitoring via a manhole antenna for transmitting and receiving the detected information is provided. It has been. Various structures of technology have been developed between the detection device in the manhole and the monitoring device on the ground. For example, Japanese Patent Application Laid-Open No. 9-26158 discloses a radio wave path for wireless communication between an underground radio and a ground station. In Japanese Patent Application Laid-Open No. 11-66484, a wireless communication manhole cover that supports a manhole cover with an insulating member interposed between the manhole cover and the conductive cover receiving portion is described in Japanese Patent Application Laid-Open No. 11-66484. In an antenna device in which an antenna having a manhole is attached to a manhole cover, the recess for connecting the manhole cover provided with a through hole in a recess provided on a part of the surface of the manhole and a feed line passing through the through hole is described above. "Manhole cover consisting of flat substrate antennas installed on the board", Utility Model Registration No. 3061715, "Measurement unit installed in manholes to input measurement values from various sensors, and said meter An on-site information processing device comprising a communication unit that is connected to the unit and radiates electromagnetic waves from within the hole of the manhole cover and that modulates the electromagnetic waves, a communication unit, and a manhole comprising a central processing unit of a management computer that receives measurement values Remote monitoring device ". As for an antenna that transmits and receives information detected in a manhole to a ground monitoring device (central processing unit), for example, “Dipole antenna embedded in a derivative that is a part of a manhole cover” in Japanese Patent Laid-Open No. 5-227073. And JP 2003-142909 A "The antenna is housed in a recess formed in a manhole cover, the upper portion thereof is covered with a dielectric cover, and the cover and the dielectric cover are fixed from the surface side of the manhole cover. It is mounted in various shapes and structures, such as a “manhole antenna”.
上記の様な通信システムによれば都市の美観を損ねる事がなく、マンホール内の情報検知器と地上の監視機器とを有線ケーブルで接続する必要がないので設置コストの低減化と監視員の保全作業が簡単である。またマンホール蓋の強度を低下させる事もなく、道路表面に近接したマンホールアンテナによって電波を照射する事ができるため性能劣化がないなどの利点から、多く利用される傾向にある。 The communication system as described above does not impair the beauty of the city, and it is not necessary to connect the information detector in the manhole to the monitoring device on the ground with a wired cable. Easy to work. In addition, there is a tendency to be frequently used because there is no deterioration in performance because radio waves can be irradiated by a manhole antenna close to the road surface without reducing the strength of the manhole cover.
しかしながら、特開平７−１４３６３１号公報や上記した特開平１１−６１８６７号公報などの様にアンテナをマンホール内に設置する事は、送受信性能を若干低下する問題があった。また特開平１１−６６４８４号公報や上記した特開平５−２２７０７号公報や特開２００３−１４２９０９号公報などの様にマンホールの蓋に凹部を設けてアンテナを収容する構造は、マンホール蓋の製作上において厄介な作業を必要としまたマンホール蓋の強度を若干損なう問題があった。 However, installing the antenna in the manhole as in Japanese Patent Laid-Open No. 7-143631 and Japanese Patent Laid-Open No. 11-61867 described above has a problem of slightly reducing transmission / reception performance. In addition, a structure in which a recess is provided in a manhole cover and an antenna is accommodated as in JP-A-11-66484, JP-A-5-22707 and JP-A-2003-142909, etc. In this case, there is a problem that a troublesome work is required and the strength of the manhole cover is slightly damaged.
本考案は、上記した従来の問題を解決する事を目的に種々検討した結果から創作されたもので、地下に埋設された上水道管などの保全情報を検知する検知機器と地上の監視機器とをマンホール蓋を介して無線通信する際にマンホールの蓋に設置しかつ検知機器から発信される保全情報の検知信号を低下させる事なく確実に送受信し、また頻繁に走行する自動車の重さにも充分に耐えられる様に製作されたマンホール蓋の強度を少しも損なう事がなく、歩道に設けられたマンホールの蓋に設置されても目立つ事もなくしかも歩行者が躓いて転ぶ事のない安全な鋳鉄製マンホール蓋用送受信アンテナを提供するものである。 The present invention was created from the results of various studies for the purpose of solving the above-mentioned conventional problems, and includes a detection device for detecting maintenance information such as a water pipe buried underground and a monitoring device on the ground. When communicating wirelessly via a manhole cover, it is installed on the manhole cover and reliably transmits and receives the detection signal of maintenance information transmitted from the detection device. Safe cast iron that does not lose its strength even if it is installed on the manhole cover provided on the sidewalk and does not stand up and fall over due to pedestrians A transmission / reception antenna for a manhole cover is provided.
