以下、本発明の実施の形態について図面を用いて説明する。なお、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

（実施の形態１）
図１は本発明の実施の形態１によるガス保安システムを示す構成図である。 (Embodiment 1)
FIG. 1 is a configuration diagram showing a gas security system according to Embodiment 1 of the present invention.

ガス設備の保安責任区分についてはガス事業者が責任を持って管理するガスボンベからガスメータまでの供給設備と、ガス消費者が管理責任を持つ消費設備に大別される。   The safety responsibilities of gas facilities can be broadly divided into supply facilities from gas cylinders to gas meters, which are managed by the gas company, and consumption facilities, which the gas consumer is responsible for.

供給設備は上流側より供給されるガスを高圧で充填されたガスボンベ１と、ガスボンベ１に直接接合されガスの流量・圧力を任意に調整することのできる調整器２と、調整器２と供給配管３によりガスを供給可能に接合されたガスメータ４からなる。   The supply equipment includes a gas cylinder 1 filled with a gas supplied from the upstream side at high pressure, a regulator 2 which is directly joined to the gas cylinder 1 and can arbitrarily adjust the flow rate and pressure of the gas, the regulator 2 and the supply piping. 3 includes a gas meter 4 joined to supply gas.

次に、図２にガスボンベ１のブロック図を示し、図３に通信装置５のブロック図を示す。図２の通り、ガスボンベ１には、信号やデータを送受信することが可能な通信装置５と通信を実施するための入力装置６が取り付けられている。そして、図３の通り通信装置５はさらに、情報や指示データを通信する通信手段５ａと、通信により送受信されるデータを記憶する記憶手段５ｂと、通信手段と記憶手段の作動を制御する制御手段５ｃからなる。   Next, FIG. 2 shows a block diagram of the gas cylinder 1, and FIG. 3 shows a block diagram of the communication device 5. As shown in FIG. 2, the gas cylinder 1 is provided with an input device 6 for performing communication with a communication device 5 capable of transmitting and receiving signals and data. As shown in FIG. 3, the communication device 5 further includes a communication unit 5a for communicating information and instruction data, a storage unit 5b for storing data transmitted and received by communication, and a control unit for controlling the operation of the communication unit and the storage unit. 5c.

次に調整器２のブロック図を図４に示す。調整器２には下流側に供給するガスの流量を調整する調整機構２ａとガスの流路を遮断するガス遮断弁２ｂと、ガスボンベ１と同じ構成の通信装置２ｃが備わり、データ通信により遮断弁２ｂの開閉を制御する。   Next, a block diagram of the regulator 2 is shown in FIG. The regulator 2 includes an adjustment mechanism 2a for adjusting the flow rate of the gas supplied to the downstream side, a gas shut-off valve 2b for shutting off the gas flow path, and a communication device 2c having the same configuration as the gas cylinder 1, and the shut-off valve by data communication. Controls opening and closing of 2b.

次にガスメータ４の構造図を図５に示す。ガスメータ４は、マイコンメータとも呼ばれ、ガスの流量を計測する計量部４ａ、ガス通路を遮断する遮断弁４ｂ、ガスメータ内部のガスの圧力を計測する圧力センサ４ｃ、通信装置４ｅを備え、それらの装置を統括するマイコン基板からなる制御部４ｄを備えている。   Next, a structural diagram of the gas meter 4 is shown in FIG. The gas meter 4 is also called a microcomputer meter, and includes a measuring unit 4a for measuring a gas flow rate, a shutoff valve 4b for shutting off a gas passage, a pressure sensor 4c for measuring a gas pressure inside the gas meter, and a communication device 4e. A control unit 4d comprising a microcomputer board that controls the apparatus is provided.

一方、消費設備の器具は、一例としてガステーブル８ａ、ガスファンヒータ８ｂ、ガス給湯器８ｃが配管７を介して接続され、ガス供給設備から供給されるガスを燃焼し、ガスを燃焼・消費する。また、消費設備に装備される安全装置としては、ガス漏れ警報機９ａ、火災警報器９ｂ、ＣＯ警報機９ｃなどが有り、ガスメータ４に有線・無線で接続されている。もし消費設備の配管７にガスの漏洩があった場合はガス漏れ警報機９ａが信号を発信し、ガスメータ４に備えられた遮断弁４ｂを遮断して安全を確保する。   On the other hand, as an example of the appliance of the consumption facility, the gas table 8a, the gas fan heater 8b, and the gas water heater 8c are connected via the pipe 7, and the gas supplied from the gas supply facility is combusted to burn and consume the gas. . Further, as a safety device equipped in the consumption facility, there are a gas leak alarm 9a, a fire alarm 9b, a CO alarm 9c, and the like, which are connected to the gas meter 4 by wire and wireless. If there is a gas leak in the piping 7 of the consuming equipment, the gas leak alarm 9a transmits a signal and shuts off the shutoff valve 4b provided in the gas meter 4 to ensure safety.

次に、本発明の実施の形態１によるガス保安システムの動作を図６のフローチャートにより説明する。まず、ガスボンベ１の入力装置６に所定の信号を入力すると、ガスボンベ１の通信装置５の制御手段５ｃは通信手段５ａによりガスメータ４（通信装置４ｅ）に所定の信号を送信する（Ｓ１）。   Next, the operation of the gas security system according to Embodiment 1 of the present invention will be described with reference to the flowchart of FIG. First, when a predetermined signal is input to the input device 6 of the gas cylinder 1, the control means 5c of the communication device 5 of the gas cylinder 1 transmits a predetermined signal to the gas meter 4 (communication device 4e) by the communication means 5a (S1).

そして、所定の信号を通信装置４ｅで受けたガスメータ４は制御部４ｄが内蔵の遮断弁４ｂを遮断するとともに、調整器２の通信装置２ｃに内蔵の遮断弁２ｂを遮断する信号を送る（Ｓ２）。   And the gas meter 4 which received the predetermined signal with the communication apparatus 4e sends the signal which interrupts | blocks the built-in cutoff valve 2b to the communication apparatus 2c of the regulator 2 while the control part 4d cuts off the built-in cutoff valve 4b (S2). ).

信号を受けた通信装置２ｃは内蔵の遮断弁２ｂを遮断するとガスメータ４に遮断が完了したことを所定の信号で通信装置４ｅへ返信する（Ｓ３）。調整器２の遮断弁２ｂの遮断が完了しとことを信号により確認したガスメータ４の制御部４ｄは内蔵の圧力センサ４ｃで、調整器２からガスメータ４までの供給配管３の圧力変動を読み取る。   Upon receiving the signal, the communication device 2c shuts off the built-in shutoff valve 2b and returns a predetermined signal to the communication device 4e that the gas meter 4 has been shut off (S3). The controller 4d of the gas meter 4 that has confirmed that the shutoff of the shutoff valve 2b of the regulator 2 has been completed by a signal reads the pressure fluctuation of the supply pipe 3 from the regulator 2 to the gas meter 4 with the built-in pressure sensor 4c.

ここで時間と圧力変動を計測したグラフの一例を図７示す。縦軸に供給配管３内部の圧力、横軸に経過時間を取っている。上流側の調整器２と下流側のガスメータ４の二つの遮断弁が閉じられた供給配管３の圧力変動を測定すると、供給配管３にガスの漏洩が無い場合は時間に対して圧力の変動はなく一定となる（Ｐ１）。しかし、配管に欠陥や腐食がある場合は、ガスが微少に漏れるため時間に対して圧力は暫時低下する（Ｐ２）。ガスメータ４は内蔵の圧力センサ４ｃでこの圧力変動を計測し、制御部４ｄはこの圧力変動データをもとに供給配管３にガスの低下、即ち漏洩がないかを判定するとともに、判定結果を記憶する（Ｓ４）。   FIG. 7 shows an example of a graph obtained by measuring time and pressure fluctuation. The vertical axis represents the pressure inside the supply pipe 3, and the horizontal axis represents the elapsed time. When the pressure fluctuation of the supply pipe 3 in which the two shutoff valves of the upstream regulator 2 and the downstream gas meter 4 are closed is measured, if there is no gas leakage in the supply pipe 3, the fluctuation of pressure with respect to time is (P1). However, if there is a defect or corrosion in the piping, the gas leaks slightly, so the pressure drops for a while (P2). The gas meter 4 measures the pressure fluctuation with the built-in pressure sensor 4c, and the control unit 4d determines whether the supply pipe 3 has a gas drop, that is, there is no leakage based on the pressure fluctuation data, and stores the determination result. (S4).

判定を終えたガスメータ４は内蔵の遮断弁４ｂを開けるとともに通信装置４ｅより調整器２（通信装置２ｃ）に所定の信号を送る（Ｓ５）。信号を受けた調整器２は遮断弁２ｂを開けるとともにガスメータ４に遮断弁２ｂを開放したことを所定の信号で返信する（Ｓ６）。二つの遮断弁が開放されたことを確認したガスメータ４の制御部４ｄは、通信装置４ｅより供給配管３のガス漏洩検査の結果を所定の信号でガスボンベ１の通信装置５に送信する（Ｓ７）。ガスメータ４から所定の信号により判定結果を受信したガスボンベ１の通信装置５は記憶手段５ｂにその結果を記憶する（Ｓ８）。ガス事業者は、供給配管３のガス漏洩検査の結果をガスボンベ１内部の通信装置５の記憶手段５ｂに記憶させて、ガスボンベ１を回収する。   The gas meter 4 having finished the determination opens the built-in shutoff valve 4b and sends a predetermined signal from the communication device 4e to the regulator 2 (communication device 2c) (S5). Receiving the signal, the regulator 2 opens the shut-off valve 2b and returns to the gas meter 4 that the shut-off valve 2b has been opened with a predetermined signal (S6). The control unit 4d of the gas meter 4 that has confirmed that the two shut-off valves are opened transmits the result of the gas leakage inspection of the supply pipe 3 from the communication device 4e to the communication device 5 of the gas cylinder 1 with a predetermined signal (S7). . The communication device 5 of the gas cylinder 1 that has received the determination result by the predetermined signal from the gas meter 4 stores the result in the storage means 5b (S8). The gas company stores the result of the gas leakage inspection of the supply pipe 3 in the storage unit 5 b of the communication device 5 inside the gas cylinder 1 and collects the gas cylinder 1.

尚、本実施例においては供給配管３のガス漏洩検査の起動をガスボンベ１の入力装置６で手動で行っているが、ガスボンベ１と調整器２及びガスメータ４の通信装置４ｅの間で自動的に実施することも可能であり、その場合ガスボンベ１の交換毎に更に確実に漏洩検査が実施・記録される。具体的にはガスボンベ１の通信装置５をＩＣタグとしガスメータ４の通信装置４ｅをＩＣタグリーダーで構成する例や、ガスボンベ１とガスメータ４の通信装置を特小無線装置で構成する例が挙げられる。   In this embodiment, the gas leakage inspection of the supply pipe 3 is manually started by the input device 6 of the gas cylinder 1, but automatically between the gas cylinder 1, the regulator 2 and the communication device 4e of the gas meter 4. It is also possible to carry out, and in that case, leakage inspection is more reliably performed and recorded every time the gas cylinder 1 is replaced. Specifically, there are an example in which the communication device 5 of the gas cylinder 1 is an IC tag and the communication device 4e of the gas meter 4 is an IC tag reader, and an example in which the communication device of the gas cylinder 1 and the gas meter 4 is an extra-small radio device. .

以上のように、本実施形態においては、ガス事業者はガスボンベの交換毎に供給配管のガス漏洩検査を実施しかつその検査結果をガスボンベとともに確実に回収することができるため、ガス供給設備の安全性を高めることが可能となる。   As described above, in this embodiment, the gas company can perform a gas leakage inspection of the supply pipe every time the gas cylinder is replaced and reliably collect the inspection result together with the gas cylinder. It becomes possible to improve the nature.

（実施の形態２）
図８は本発明の第２の実施の形態によるガス保安システムの動作を示すフローチャートである。まず、ガスボンベ１の入力装置６に所定の信号を入力すると、通信装置５の制御手段５ｃは通信手段５ａによりガスメータ４（通信装置４ｅ）に所定の信号を送信する（Ｓ９）。所定の信号を通信装置４ｅで受けたガスメータ４は制御部４ｄが、通信装置４ｅにより、消費設備に有線・無線で接続・設置された各種の安全装置、ガス漏れ警報機９ａ、火災警報器９ｂ、ＣＯ警報機９ｃに所定の信号を発信する（Ｓ１０）。 (Embodiment 2)
FIG. 8 is a flowchart showing the operation of the gas security system according to the second embodiment of the present invention. First, when a predetermined signal is input to the input device 6 of the gas cylinder 1, the control means 5c of the communication device 5 transmits a predetermined signal to the gas meter 4 (communication device 4e) by the communication means 5a (S9). When the gas meter 4 receives a predetermined signal by the communication device 4e, the control unit 4d uses the communication device 4e to connect and install various safety devices wired / wirelessly to the consumption facility, a gas leak alarm 9a, a fire alarm 9b. Then, a predetermined signal is transmitted to the CO alarm device 9c (S10).

ガスメータ４から所定の信号を受信した各安全装置は、器具の安全機能の自己診断を実施し結果をガスメータ４（通信装置４ｅ）に返信する（Ｓ１１）。各安全装置より自己診断結果を受信したガスメータ４の制御部４ｄはその結果とともに、ガスボンベ１の交換までに記憶している過去の安全装置の作動履歴、またガスメータ４に内蔵の遮断弁４ｂの作動履歴と作動理由を、通信装置４ｅより所定の信号でガスボンベ１の通信装置５に送信する（Ｓ１２）。ガスメータ４から所定の信号により安全装置の作動履歴を受信したガスボンベ１の通信装置５は記憶手段５ｂにその結果を記憶する（Ｓ１３）。ガス事業者は、安全装置の作動履歴の結果をガスボンベ１内部の通信装置５の記憶手段５ｂに記憶させて、ガスボンベ１を回収する。   Each safety device that has received the predetermined signal from the gas meter 4 performs a self-diagnosis of the safety function of the instrument and returns the result to the gas meter 4 (communication device 4e) (S11). The control unit 4d of the gas meter 4 that has received the self-diagnosis result from each safety device, together with the result, the past operation history of the safety device stored until the replacement of the gas cylinder 1, and the operation of the shut-off valve 4b built in the gas meter 4 The history and the operation reason are transmitted from the communication device 4e to the communication device 5 of the gas cylinder 1 by a predetermined signal (S12). The communication device 5 of the gas cylinder 1 that has received the operation history of the safety device by a predetermined signal from the gas meter 4 stores the result in the storage means 5b (S13). The gas company stores the result of the operation history of the safety device in the storage unit 5 b of the communication device 5 inside the gas cylinder 1 and collects the gas cylinder 1.

以上のように、本実施形態においては、ガス事業者はガスボンベの交換毎にガス消費設備の安全装置の作動点検を実施しかつその検査結果と作動履歴をガスボンベとともに確実に回収することができるため、ガス供給設備の安全性を高めることが可能となる。またガス事業者はガス供給設備と消費設備の検査結果を一元的にガスボンベに記録することができるため、供給設備と消費設備の総合的な安全性を高めることが可能となる。   As described above, in this embodiment, the gas company can check the operation of the safety device of the gas consuming equipment every time the gas cylinder is replaced, and reliably collect the inspection result and the operation history together with the gas cylinder. It becomes possible to increase the safety of the gas supply equipment. In addition, since the gas company can centrally record the inspection results of the gas supply facility and the consumption facility in the gas cylinder, it is possible to improve the overall safety of the supply facility and the consumption facility.

以上のように、本発明にかかるガス保安システムは、ガスボンベ、調整器とガスメータを無線接続し、ガス供給設備とガス消費設備の検査を一括的自動的に実施可能となるため、今後発展する無線技術を使った２４時間集中監視でガス供給から消費設備までの全体を監視するガス保安システムに応用できる。   As described above, the gas security system according to the present invention wirelessly connects the gas cylinder, the regulator, and the gas meter, and can automatically perform the inspection of the gas supply facility and the gas consumption facility collectively. It can be applied to a gas security system that monitors the entire process from gas supply to consumption equipment by 24-hour centralized monitoring using technology.
