Description

【０００１】
【発明の属する技術分野】
本発明は、地震発生時に、集合住宅のガス供給の安全を確保する地震保安システムに関するものである。
【０００２】
【従来の技術】
従来、この種の地震保安システムは、内蔵する感震器の信号を判定処理し信号送信する複数の通信型ガス保安メータから構成されていた（例えば、特許文献１参照）。
【０００３】
【特許文献１】
特開平１０−１２４１０１号公報（図１）
【０００４】
【発明が解決しようとする課題】
しかしながら、このような地震保安システムは、地震発生時には各戸毎の通信型ガス保安メータで家庭内のガス供給を停止する事は可能であったが、各戸までのパイプシャフト等の配管上に漏れが発生した場合には対処することが不可能であった。また各通信型ガス保安メータから同時に遮断情報の送信がなされるため、回線処理上で同送を防ぐ処理が必要であった。さらに集合住宅にあっては、感震レベルは同一であるにも拘わらず、各戸毎の通信型ガス保安メータに感震器を搭載しているという経済的なムダがあった。
【０００５】
本発明は、上記従来の問題点を解決すべく創案されたもので、地震の発生後直ちに、ガス供給管に接続され無線通信用親機を有するガス供給遮断手段によって、自動的に集合住宅内のガス供給を停止する地震保安システムを提供することを目的とする。
【０００６】
【課題を解決するための手段】
上記課題を解決するために、無線通信用子機を有する複数の通信型のガス保安メータと、ガス供給管に接続され、感震器と無線通信用親機とを有し、前記感震器からの信号を判定処理しガスの供給を止めるガス供給遮断手段とを備えたものである。
【０００７】
上記発明によれば、地震の発生後、直ちに且つ自動的にガスの供給を停止することが可能な地震保安システムを提供することができる。
【０００８】
【発明の実施の形態】
本発明は、集合住宅内の複数の通信型ガス保安メータと、このガス保安メータに接続された無線通信用子機と、集合住宅のガス供給管上に設置され、内部に感震器と、前記感震器の信号を判定処理しガス供給を止めるガス供給遮断手段とを有する無線通信用親機とで構成されたものである。この構成により、地震の発生後直ちに、自動的に集合住宅内のガス供給を停止し、火災の誘発を未然に防ぐことが可能となる。
【０００９】
また、無線通信用親機は、ガス供給遮断手段作動時には、無線通信用子機が接続された全ての通信型ガス保安メータに遮断信号を送信するものである。この構成により、集合住宅のガス供給管上だけでなく各戸毎にもガス供給を停止できるため地震発生時の保安性能をさらに向上することが可能となる。
【００１０】
また、通信型ガス保安メータは、無線通信用親機からの遮断信号受信時には、遮断表示する表示手段を有するするものである。この構成により、地震時には各戸毎にガス供給が停止状態にあるかどうかを容易に判別することが可能となる。
【００１１】
さらにまた、無線通信用親機は、ガス供給遮断手段作動した後は、無線通信用子機が接続された全ての通信型ガス保安メータからの復帰信号を確認した後のみ、ガス供給遮断手段の復帰が可能となるものである。この構成により、地震被害確認後のガス供給再開時には、各戸毎の安全確認を漏れなく行うことが必要となり、未確認のままガス供給を行うミスを防ぐことが可能となる。
【００１２】
【実施例】
以下本発明の実施例について図面を用いて説明する。
【００１３】
（実施例１）
図１は本発明の実施例１の地震保安システムの構成図である。図１において、１は集合住宅内の各戸毎に設置された通信型ガス保安メータ、２はガス保安メータに接続された無線通信用子機、３は無線通信用親機内部に設けられた感震器、４は感震器の信号を判定処理しガス供給を止めるガス供給遮断手段、５は集合住宅のガス供給管上に設置され、ガス供給遮断手段作動時には、無線通信用子機が接続された全ての通信型ガス保安メータに遮断信号を送信する無線通信用親機、６は通信型ガス保安メータ内に設けられ、無線通信用親機からの遮断信号受信時に遮断表示する表示手段、７は無線通信用親機内に設けられ、ガス供給遮断手段作動した後は、無線通信用子機が接続された全ての通信型ガス保安メータからの復帰信号を確認した後、ガス供給遮断手段の復帰が可能となる判定手段である。
【００１４】
次に作用を説明する。無線通信用親機と子機からなるガス供給地震保安システムを有する集合住宅で地震が発生した場合、無線通信用親機５は内蔵する感震器３により、その地震の強弱をレベル判定し、そのレベルに応じて集合住宅のガス供給配管のガス供給を遮断し、遮断信号を無線通信用子機２が接続された集合住宅内の各戸毎に設置された通信型ガス保安メータ１にデータ送信する。通信型保安ガスメータ１は、無線通信用親機１から送られてきた遮断信号のデータを受信すると、個別にもガス供給の遮断を行い、遮断表示を内蔵する表示手段６にて行う。
【００１５】
また無線通信用親機５は、地震被害確認後のガス供給再開時には、通信型ガス保安メータ１の個別の遮断復帰を行ったデータを受信し、接続された全ての無線通信用子機からの復帰情報を受け取った後、ガス供給配管の遮断解除を行うことができる。
【００１６】
【発明の効果】
本発明の地震保安システムによれば、地震発生時に通信型ガス保安メータによって家庭内のガス供給を停止できることは勿論、家庭まで配管されているパイプシャフト等の配管上の漏れまでも防止することができるという効果を奏する。

BACKGROUND OF THE INVENTION
The present invention relates to an earthquake security system that ensures the safety of gas supply to a housing complex when an earthquake occurs.
[0002]
[Prior art]
Conventionally, this type of seismic safety system has been composed of a plurality of communication-type gas safety meters that determine and transmit signals from built-in seismic sensors (see, for example, Patent Document 1).
[0003]
[Patent Document 1]
JP-A-10-124101 (FIG. 1)
[0004]
[Problems to be solved by the invention]
However, in such an earthquake safety system, it was possible to stop the gas supply in the home with a communication gas safety meter for each door at the time of the earthquake occurrence, but there was a leak on the piping such as the pipe shaft to each door. It was impossible to deal with it when it occurred. Moreover, since the communication information is simultaneously transmitted from each communication type gas security meter, a process for preventing the transmission on the line processing is necessary. Furthermore, in the housing complex, there was an economic waste that the seismic device was mounted on the communication gas security meter for each house, even though the seismic level was the same.
[0005]
The present invention was devised to solve the above-mentioned conventional problems. Immediately after the occurrence of an earthquake, the gas supply cut-off means connected to the gas supply pipe and having a master unit for wireless communication automatically The purpose is to provide an earthquake security system that stops the gas supply.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, a plurality of communication-type gas safety meters having wireless communication slave units, a gas supply pipe connected to a seismic device and a wireless communication master unit, And a gas supply shut-off means for stopping the gas supply by determining the signal from the signal.
[0007]
According to the above invention, it is possible to provide an earthquake security system that can immediately and automatically stop the supply of gas after an earthquake occurs.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The present invention includes a plurality of communication type gas safety meters in an apartment house, a wireless communication slave connected to the gas safety meter, a gas supply pipe of the apartment house, It is comprised with the main | base station for radio | wireless communication which has the gas supply interruption | blocking means which judges the signal of the said seismic device, and stops gas supply. With this configuration, immediately after the occurrence of the earthquake, it is possible to automatically stop the gas supply in the apartment house and prevent a fire from occurring.
[0009]
Further, the base station for wireless communication transmits a cut-off signal to all communication type gas safety meters connected to the handset for wireless communication when the gas supply shut-off means is activated. With this configuration, since the gas supply can be stopped not only on the gas supply pipe of the apartment house but also for each house, it is possible to further improve the safety performance in the event of an earthquake.
[0010]
The communication-type gas safety meter has a display means for displaying a cut-off signal when receiving a cut-off signal from the base station for wireless communication. With this configuration, it is possible to easily determine whether the gas supply is stopped for each house during an earthquake.
[0011]
Furthermore, the radio communication master unit, after the gas supply shut-off means is activated, only after confirming the return signals from all communication-type gas safety meters to which the radio communication slave units are connected, It is possible to return. With this configuration, when resuming the gas supply after confirming the earthquake damage, it is necessary to confirm the safety of each house without omission, and it is possible to prevent mistakes in supplying the gas without confirmation.
[0012]

[0014]
Next, the operation will be described. When an earthquake occurs in an apartment house with a gas supply earthquake security system consisting of a base unit for wireless communication and a handset, the base unit for wireless communication 5 uses the built-in seismic sensor 3 to determine the level of the strength of the earthquake, Depending on the level, the gas supply piping of the housing complex is cut off, and the cut-off signal is transmitted to the communication gas security meter 1 installed in each house in the housing complex to which the wireless communication cordless handset 2 is connected. To do. When the communication type safety gas meter 1 receives the data of the cut-off signal sent from the wireless communication master unit 1, the communication type security gas meter 1 cuts off the gas supply individually and performs it with the display means 6 incorporating the cut-off display.
[0015]
In addition, when the gas supply is resumed after the earthquake damage is confirmed, the wireless communication master unit 5 receives the data of the individual disconnection / recovery of the communication gas safety meter 1, and receives data from all the connected wireless communication slave units. After receiving the return information, the cutoff of the gas supply pipe can be released.
