Description

本発明は、ガス遮断装置に関し、特に内部電源の消耗度合いを抑制するものである。   The present invention relates to a gas shut-off device, and particularly suppresses the degree of consumption of an internal power supply.

従来、この種のガス遮断装置である無線自動検針システムにおいて、メータで検針したデータを含む情報を収集すべく無線回線を介してメータに設けられた無線機子機と通信を行う無線機親機を有し、その無線機親機は特定小電力無線にて無線機子機との無線通信を行うと共に携帯電話回線やテレターミナル無線回線を介してセンター装置側と通信するようにしたものである(例えば、特許文献1参照)。

JP 2001-111701 A

ところで、上記従来の構成では、ガス流量を測定する流量検出部やガス流量を遮断する遮断弁を内蔵するガス遮断装置と、測定したガス流量値をガス管理センターへ送信する通信機器とが別筐体として構成され、それぞれが独立して作動することが可能であった。   By the way, in the conventional configuration described above, a gas shut-off device incorporating a flow rate detecting unit for measuring the gas flow rate and a shut-off valve for shutting off the gas flow rate and a communication device for transmitting the measured gas flow rate value to the gas management center are separately provided. It was configured as a body and each could operate independently.

しかし、上記流量検出部や遮断弁と通信部とを一体にしてガス遮断装置を構成すると、通信部が新たに加わったことにより電池などの内部電源の消耗は大幅に増加してしまい、特にガス流量の測定や遮断といった制御と、通信制御とを同時に行った場合は、その負荷は大きなものとなり、電池寿命が短くなるという課題が挙げられる。   However, if the gas shut-off device is configured by integrating the flow rate detection unit, the shut-off valve, and the communication unit, the consumption of internal power sources such as batteries is greatly increased due to the addition of the communication unit. When control such as measurement and shut-off of the flow rate and communication control are performed at the same time, there is a problem that the load becomes large and the battery life is shortened.

本発明は上記課題を解決するもので、ガス流量の遮断動作やガス管理センターへ流量値を送信するときには、ガス流量を遮断する遮断弁を開閉駆動させる遮断制御部とガス管理センターとの無線通信を行う通信部との間でデータ伝送を行わないようにしたものである。   SUMMARY OF THE INVENTION The present invention solves the above problems, and when a gas flow shutoff operation or a flow rate value is transmitted to a gas management center, wireless communication between a shutoff control unit that opens and closes a shutoff valve that shuts off the gas flow rate and the gas management center. Data transmission is not performed between the communication unit and the communication unit.

以下、本発明の実施の形態について、図面を参照しながら説明する。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)

(Embodiment)
FIG. 1 is an overall configuration diagram of a communication mode between a gas cutoff device, a base station, and a customer's house in an embodiment of the present invention.

ガス遮断装置100は、各家庭のガス供給管の入口部分に設置され、このガス遮断装置
100を経由した後のガス配管から分岐して家庭で使用する種々のガス器具が設置された場所まで配管されガスが供給される。例えば、屋外にはガス給湯器が設置され、このガス給湯器で生成される湯が水配管を介して台所の給湯栓、浴槽やシャワー装置が設置された風呂、リビング等に設置された床暖房に供給され、種々の使用形態を形成している。
The gas shut-off device 100 is installed at the entrance of the gas supply pipe of each household, and is branched from the gas pipe after passing through the gas shut-off device 100 to the place where various gas appliances used at home are installed. Gas is supplied. For example, a gas water heater is installed outdoors, and hot water generated by the gas water heater is connected to a kitchen hot water tap, a bath provided with a bathtub or shower device, a floor heater installed in a living room, etc. To form various usage forms.

また、屋内にあっては、台所に設置されたガステーブル、リビングや寝室等に設置されたガスファンヒータにガスが供給され、必要に応じて適宜使用される。   In addition, when indoors, gas is supplied to a gas table installed in a kitchen, a gas fan heater installed in a living room, a bedroom, or the like, and is used as needed.

そして、設置されたガス器具が使用されガスの消費が発生するとガス遮断装置100でその使用量が計測され、そのデータが所定期間毎に累積記憶されている。このガス遮断装置100に記憶されたデータはガス管理センター200からの定期的なデータ要求指令に基づいて所定の情報処理を行った後、ガス料金やガス使用量あるいはガス管理センター200が提供する割引サービス等の情報として需要家及びガス事業者に送信される。その際、後述するようにガス遮断装置100に設けられた通信部を用いて基地局300へ、ガス料金やガス使用量あるいはガス管理センター200が提供する割引サービス等の情報を送信し、基地局300で受信できた情報は公衆回線網などを介してガス管理センター200へ送信される。   When the installed gas appliance is used and gas consumption occurs, the gas shut-off device 100 measures the amount of use, and the data is accumulated and stored every predetermined period. The data stored in the gas shut-off device 100 is subjected to predetermined information processing based on a periodic data request command from the gas management center 200, and then a gas fee, a gas usage amount, or a discount provided by the gas management center 200. Information such as services is transmitted to consumers and gas companies. At that time, as will be described later, the base station 300 is transmitted to the base station 300 by using a communication unit provided in the gas shut-off device 100, and information such as a gas fee, a gas usage amount, a discount service provided by the gas management center 200, etc. Information received at 300 is transmitted to the gas management center 200 via a public network or the like.

図2は、本発明の実施の形態におけるガス遮断装置100の構成図を示すものである。ガス遮断装置100は、ガス流路中を流れるガスの流量を測定する流量検出部101と、前記流量検出部101からの信号に基づいてガス流路を開閉する遮断弁102と、前記遮断弁102を駆動する制御部103とを備えており、これらは同一プリント配線板104上に配置されている。   FIG. 2 shows a configuration diagram of the gas cutoff device 100 according to the embodiment of the present invention. The gas cutoff device 100 includes a flow rate detection unit 101 that measures the flow rate of gas flowing in the gas flow path, a cutoff valve 102 that opens and closes the gas flow path based on a signal from the flow rate detection unit 101, and the cutoff valve 102. And a control unit 103 for driving the same, and these are arranged on the same printed wiring board 104.

また、プリント配線板104上の制御部103は、ガス遮断の判断、ガス使用量の測定や積算等の保安機能の制御を行い、さらには火災警報器やCO警報器やホームセキュリティー機器等の外部機器からの受信データを判定し、遮断弁などの制御に活かすことができる。   In addition, the control unit 103 on the printed wiring board 104 performs the control of safety functions such as judgment of gas interruption, measurement of gas usage and integration, and further external devices such as fire alarms, CO alarms, and home security devices. Can be used for the control of shutoff valves and the like.

さらに、プリント配線板104上には通信部110が実装されており、これを用いて基地局300と無線通信を行うことができる。通信部110は、ガスメータ装置100の内部に設置することからなるべく小型であることが望ましく、例えば通信モジュールなどが好ましい。この通信モジュール(通信部110)は、無線送受信機能、マイコン機能を一体に封止して実装したもので、実装基板上にマイコン機能を配置する必要がない。また、無線部110では、400MHz帯や1.2GHz帯、2.4GHz帯を用いた特定小電力無線通信を行っている。   Further, a communication unit 110 is mounted on the printed wiring board 104, and wireless communication with the base station 300 can be performed using the communication unit 110. The communication unit 110 is preferably as small as possible because it is installed inside the gas meter device 100, and for example, a communication module is preferable. This communication module (communication unit 110) is a unit in which a wireless transmission / reception function and a microcomputer function are integrally sealed and does not need to be arranged on a mounting board. The wireless unit 110 performs specific low-power wireless communication using a 400 MHz band, a 1.2 GHz band, or a 2.4 GHz band.

なお、流量検出部101、制御部103や通信部110は、リチウム電池などの内部電源部111を電力供給源としており、蓄積電力量が消耗されると、新たなリチウム電池に交換することができる。   The flow rate detection unit 101, the control unit 103, and the communication unit 110 use the internal power supply unit 111 such as a lithium battery as a power supply source, and can be replaced with a new lithium battery when the stored power amount is consumed. .

次に、制御部103と通信部106との間のデータ通信について説明する。まずは、通信部106から制御部103へデータが伝送される場合について説明する。   Next, data communication between the control unit 103 and the communication unit 106 will be described. First, a case where data is transmitted from the communication unit 106 to the control unit 103 will be described.

震発生時や周辺地区の災害発生時といった緊急時にガス流量を遮断するため、ガス管理センター200はそれぞれのガス遮断装置100に対してガス遮断要求信号を発する。そのガス遮断要求信号は、まず無線部110で受信される。そして、無線部110は制御部103からの伝送許可ビットを確認する。伝送許可ビットとは、ON(High)、OFF(Low)の2値で表される信号である。ここで、無線部110が伝送許可ビットを確認してON(High)であれば、ガス遮断要求信号を制御部103へ伝送できる。一方
で、無線部110が伝送許可ビットを確認してOFF(Low)であれば、ガス遮断要求信号を制御部103へ伝送できないので、伝送許可ビットがON(High)となるまで伝送を待つことになる。
In order to shut off the gas flow rate in an emergency such as an earthquake or a disaster in the surrounding area, the gas management center 200 issues a gas cutoff request signal to each gas cutoff device 100. The gas cutoff request signal is first received by the wireless unit 110. Then, the wireless unit 110 confirms the transmission permission bit from the control unit 103. The transmission permission bit is a signal represented by a binary value of ON (High) and OFF (Low). Here, if the wireless unit 110 confirms the transmission permission bit and is ON (High), the gas cutoff request signal can be transmitted to the control unit 103. On the other hand, if the wireless unit 110 confirms the transmission permission bit and is OFF (Low), the gas cut-off request signal cannot be transmitted to the control unit 103, so the transmission waits until the transmission permission bit becomes ON (High). become.

このようにして制御部103がガス遮断要求信号を受信できると、制御部103は遮断弁102を制御して、ガス流量を遮断する。   When the control unit 103 can receive the gas cutoff request signal in this way, the control unit 103 controls the cutoff valve 102 to shut off the gas flow rate.

ここで、図4を用いて制御部103が伝送許可ビットを出力する処理手順を説明する。まず、制御部103は流量検出部101または遮断弁102を制御しているかを確認する(S401)。S401において、もしも制御部103が流量検出部101か遮断弁102を制御していれば、伝送許可ビットとしてOFF(Low)を出力する(S402)。また、S401において制御部103が流量検出部101か遮断弁102を制御していなければ、伝送許可ビットとしてON(High)を出力する(S403)。   Here, a processing procedure in which the control unit 103 outputs the transmission permission bit will be described with reference to FIG. First, the control unit 103 confirms whether the flow rate detection unit 101 or the shutoff valve 102 is controlled (S401). In S401, if the control unit 103 controls the flow rate detection unit 101 or the shutoff valve 102, OFF (Low) is output as a transmission permission bit (S402). If the control unit 103 does not control the flow rate detection unit 101 or the shutoff valve 102 in S401, ON (High) is output as a transmission permission bit (S403).

なお、図4では制御部103が火災警報器やCO警報器やホームセキュリティー機器等の外部機器からのデータを受信していれば、伝送許可ビットとしてOFF(Low)を出力し、受信していなければ伝送許可ビットとしてON(High)を出力するような形態であってもよい。   In FIG. 4, if the control unit 103 receives data from an external device such as a fire alarm device, a CO alarm device, or a home security device, it outputs OFF (Low) as a transmission permission bit. It may be configured to output ON (High) as the transmission permission bit.

次に、制御部103から通信部106へデータが伝送される場合について説明する。上記で説明したように、ガス遮断要求信号を受信してガス流量を遮断した後、制御部103は、通信部106を介してガス管理センター200へ遮断完了信号を送信する。   Next, a case where data is transmitted from the control unit 103 to the communication unit 106 will be described. As described above, after receiving the gas cutoff request signal and shutting off the gas flow rate, the control unit 103 transmits a cutoff completion signal to the gas management center 200 via the communication unit 106.

ガス流量遮断後、制御部103は無線部110からの伝送許可ビットを確認する。無線部110からの伝送許可ビットを確認してON(High)であれば、遮断完了信号を無線部110へ伝送できる。一方で、無線部110からの伝送許可ビットを確認してOFF(Low)であれば、遮断完了信号を無線部110へ伝送できないので、伝送許可ビットがON(High)となるまで伝送を待つことになる。   After the gas flow rate is cut off, the control unit 103 checks the transmission permission bit from the wireless unit 110. If the transmission permission bit from the wireless unit 110 is confirmed and turned ON (High), a cutoff completion signal can be transmitted to the wireless unit 110. On the other hand, if the transmission permission bit from the wireless unit 110 is confirmed and is OFF (Low), the cutoff completion signal cannot be transmitted to the wireless unit 110, and thus waiting for transmission until the transmission permission bit becomes ON (High). become.

このようにして無線部110が遮断完了信号を受信できると、基地局300を介してガス管理センター200へ遮断完了信号を送信することができる。   When the wireless unit 110 can receive the cutoff completion signal in this way, the cutoff completion signal can be transmitted to the gas management center 200 via the base station 300.

ここで、図5を用いて無線部110が伝送許可ビットを出力する処理手順を説明する。まず、無線部110は外部(基地局300)からデータを送信または受信中であるかを確認する(S501)。S501において、もしも無線部110が外部からデータを送受信中であれば、伝送許可ビットとしてOFF(Low)を出力する(S502)。また、S501において無線部110が外部(基地局300)からデータを送受信中でなければ、伝送許可ビットとしてON(High)を出力する(S503)。   Here, a processing procedure in which the wireless unit 110 outputs the transmission permission bit will be described with reference to FIG. First, the wireless unit 110 confirms whether data is being transmitted or received from the outside (base station 300) (S501). In S501, if the wireless unit 110 is transmitting / receiving data from the outside, OFF (Low) is output as a transmission permission bit (S502). If the wireless unit 110 is not transmitting or receiving data from the outside (base station 300) in S501, ON (High) is output as a transmission permission bit (S503).

なお、無線部110が外部からデータを送受信中であるとき、優先的にそのデータを受信して一時的に保存しておき、遮断完了信号をガス管理センター200へ送信完了後に、外部からのデータを制御部103へ伝送することができる。   Note that when the wireless unit 110 is transmitting / receiving data from the outside, the data is preferentially received and temporarily stored, and after the completion of transmission of the cutoff completion signal to the gas management center 200, data from the outside is received. Can be transmitted to the control unit 103.

したがって、上記によれば、遮断動作や流量測定動作、外部機器(火災警報器やCO警報器やホームセキュリティー機器等)やガス管理センター200からのデータ送受信中に、制御部103と通信部106との間でデータ伝送を一時的に行わないため、内部電源部111は同時に大電流を消費することが無く、放電末期に内部抵抗が増加するという負荷の増加を抑制できることから、電池の寿命が短くなることを防止できる。   Therefore, according to the above, during the data transmission / reception from the gas management center 200 during the interruption operation, the flow measurement operation, the external device (fire alarm device, CO alarm device, home security device, etc.), the control unit 103 and the communication unit 106 The internal power supply unit 111 does not consume a large amount of current at the same time, and can suppress an increase in load that increases the internal resistance at the end of discharge, thereby shortening the battery life. Can be prevented.

なお、図5に示した無線部110の処理において、遮断情報を一刻も早急にガス管理セ
ンター200へ送信する必要があるという場合では、制御部103からの遮断完了信号(その他データ信号であってもよく、遮断完了信号に限るものではない)を優先的に扱うような形態であってもよい。この場合であれば、制御部103から無線部110へデータ伝送するタイミングで、強制伝送ビットを用いて無線部110に知らせることができる。すなわち、無線部110が強制伝送ビットOFF(Low)を確認している間は図5の処理を行い、もしも無線部110が強制伝送ビットON(High)を確認すれば、無線部110は外部からのデータ送受信を一旦中断し、制御部103からの遮断完了信号を無線部110へ伝送する。
In the process of the wireless unit 110 shown in FIG. 5, when it is necessary to transmit the cutoff information to the gas management center 200 as soon as possible, the cutoff completion signal (other data signal is sent from the control unit 103). In other words, it is not limited to the shutoff completion signal. In this case, the wireless unit 110 can be notified using the forced transmission bit at the timing of data transmission from the control unit 103 to the wireless unit 110. That is, while the wireless unit 110 confirms the forced transmission bit OFF (Low), the process of FIG. 5 is performed. If the wireless unit 110 confirms the forced transmission bit ON (High), the wireless unit 110 is externally connected. Is temporarily interrupted, and a cutoff completion signal from the control unit 103 is transmitted to the wireless unit 110.

これによれば、ガス事業者からの無線通信により、地震発生時や周辺地区の災害発生時等の緊急時にガス通路を遮断することができる。   According to this, the gas passage can be shut off in an emergency such as an earthquake or a disaster in the surrounding area by wireless communication from the gas company.

また、上記と同様にして図4に示した制御部103の処理において強制伝送ビットを用いても良いことは言うまでもない。それによれば、ガス事業者が緊急出動しなければならない場合や、ホームセキュリティー機能を有した警報を発する外部機器との連動が必要な場合に、外部機器又はガス管理センター200との無線通信状況に関わらず、送信データを外部機器7又はガス管理センター200に送信することができる。   Further, it goes without saying that the forced transmission bit may be used in the processing of the control unit 103 shown in FIG. 4 in the same manner as described above. According to this, when a gas company has to call out urgently or when it is necessary to link with an external device that issues an alarm having a home security function, the wireless communication status with the external device or the gas management center 200 is affected. Instead, the transmission data can be transmitted to the external device 7 or the gas management center 200.

以上のように、本発明にかかるガス遮断装置は、内部電源に対する負荷の集中を抑制し、内部電源の寿命低下を抑制することができる。   As described above, the gas shutoff device according to the present invention can suppress the concentration of the load on the internal power supply and suppress the decrease in the lifetime of the internal power supply.
