(実施の形態1)
図1は、本発明による警報器対応ガスメータシステムを示す図である。
(Embodiment 1)
FIG. 1 is a diagram showing an alarm-compatible gas meter system according to the present invention.

ガス導入管8から供給されたガスは、ガスメータ1を介し、ガス供給管9を経由して、ガス器具A5、ガス器具B6、ガス器具C7のそれぞれへ供給されるようになっている。ガスメータ1は、通過する流量を計測するための計測手段10と、この計測手段10により計測された流量及び流量の変化パターンに基づいて私用されているガス機器の種類を判定するガス機器判定手段11及び後述の警報器と通信を行うための双方向通信手段12を備えている。警報器A2、警報器B3、警報器C4はガス器具A5、ガス器具B6、ガス
器具C7の近傍に設置されており、それぞれ双方向通信手段2a、3a、4aを有しガスメータ1と双方向通信を行うことができるようになっている。
The gas supplied from the gas introduction pipe 8 is supplied to each of the gas appliance A5, the gas appliance B6, and the gas appliance C7 via the gas meter 1 and the gas supply pipe 9. The gas meter 1 includes a measuring unit 10 for measuring a flow rate passing therethrough, and a gas device determining unit that determines a type of a gas device that is privately used based on a flow rate measured by the measuring unit 10 and a change pattern of the flow rate. 11 and a bidirectional communication means 12 for communicating with an alarm device described later. The alarm device A2, the alarm device B3, and the alarm device C4 are installed in the vicinity of the gas appliance A5, the gas appliance B6, and the gas appliance C7. Can be done.

以下、ガスメータ1には、ガス器具A5が設置された部屋に警報器A2が、ガス器具B6が設置された部屋に警報器B3が、ガス器具C7が設置された部屋に警報器C4が設置されていることが情報として、登録されている状態での動作例を説明する。   Hereinafter, in the gas meter 1, the alarm device A2 is installed in the room where the gas appliance A5 is installed, the alarm device B3 is installed in the room where the gas appliance B6 is installed, and the alarm device C4 is installed in the room where the gas appliance C7 is installed. As an example, an operation example in a registered state will be described.

ガス器具A5が動作しているとガスメータ1が判断しているときに、警報器A2が異常を検知した時、ガスメータ1はガスの供給を遮断するとともに、警報器A2、警報器B3、警報器C4に通信を行い、警報器A2が設置された部屋でガス器具が関連した異常が発生していることを、報知するよう指示を出す。   When the gas meter 1 determines that the gas appliance A5 is operating and the alarm device A2 detects an abnormality, the gas meter 1 shuts off the gas supply, and the alarm device A2, the alarm device B3, and the alarm device Communication is performed to C4, and an instruction is given to notify that an abnormality related to the gas appliance has occurred in the room where the alarm device A2 is installed.

また、ガス器具A5が動作していないとガスメータ1が判断しているときに、警報器A2が異常を検知したときはガスメータ1はガスの供給を遮断せずに、警報器A2、警報器B3、警報器C4に通信を行い、警報器A2が設置された部屋でガス器具以外で異常が発生していることを、報知するよう指示を出す。   Further, when the gas meter 1 determines that the gas appliance A5 is not operating and the alarm device A2 detects an abnormality, the gas meter 1 does not shut off the gas supply, and the alarm device A2 and the alarm device B3. Communicate to the alarm device C4 and issue an instruction to notify that an abnormality has occurred in a room other than the gas appliance in the room where the alarm device A2 is installed.

この時、ガス器具での異常とガス器具以外での異常を区別しやすくするために警報器が発する音色やメロディ、警告音を変えることも手段として有効である。   At this time, it is also effective as a means to change the tone color, melody, and warning sound emitted by the alarm device in order to easily distinguish between abnormality in the gas appliance and abnormality in other than the gas appliance.

なお、他のガス器具と警報器との組み合わせでも同様で、ガス器具B6のみが動作しているとガスメータ1が判断しているときに、警報器C4が異常を検知した場合は、ガスを遮断せずにガス器具以外の異常であることを報知する。   The same applies to combinations of other gas appliances and alarm devices. When the gas meter 1 determines that only the gas appliance B6 is operating, the alarm device C4 shuts off the gas if it detects an abnormality. Notify that there is an abnormality other than gas appliances.

ここで、どの警報器からの警報情報であればガスメータがガスを遮断するかの設定は、ガス器具・警報器個々の設置状態や、家屋構造等によって最適に行えることも可能である。   Here, the alarm information from which alarm device the gas meter shuts off the gas can be optimally set according to the installation state of the gas appliance / alarm device, the house structure, and the like.

次に、ガスメータ1に、ガス器具A5が設置された部屋に警報器A2が、ガス器具B6が設置された部屋に警報器B3が、ガス器具C7が設置された部屋に警報器C4が設置されていることを情報として登録するための手段の例を下記に示す。   Next, in the gas meter 1, the alarm device A2 is installed in the room where the gas appliance A5 is installed, the alarm device B3 is installed in the room where the gas appliance B6 is installed, and the alarm device C4 is installed in the room where the gas appliance C7 is installed. Examples of means for registering information as information are shown below.

第1の例としては、ガス器具および警報器を設置したときに、ガスメータ1に個別に情報入力することにより登録する方法がある。   As a first example, there is a method of registering by inputting information individually to the gas meter 1 when a gas appliance and an alarm device are installed.

第2の例としては、ガス器具が動作したときに発生する熱や排気ガスの状態を警報器のセンサーが検知し、ガス器具が動作したガス消費パターンをガスメータ1が検知し、ガス消費パターンと警報器のセンサーの検知信号とを関連付けてどのガス器具とどの警報器が関連しているかを自動判別して登録する方法がある。   As a second example, the sensor of the alarm device detects the state of heat and exhaust gas generated when the gas appliance is operated, the gas consumption pattern when the gas appliance is operated is detected by the gas meter 1, and the gas consumption pattern and There is a method of automatically identifying and registering which gas appliance is associated with which alarm device by associating the detection signal of the sensor of the alarm device.

また、警報器A2、警報器B3、警報器C4は個々にガスメータ1と双方向通信するのではなく、たとえば、警報器A2が警報器の親機として代表でガスメータ1と双方向通信を行い、警報器B3、警報器C4は親機の警報器A2を介してガスメータ1と通信を行うシステムでもかまわない。 なお、警報器とガスメータとの通信は、有線でも無線でもかまわない。   In addition, the alarm device A2, the alarm device B3, and the alarm device C4 do not communicate bidirectionally with the gas meter 1, but for example, the alarm device A2 typically performs bidirectional communication with the gas meter 1 as a master unit of the alarm device, The alarm device B3 and the alarm device C4 may be a system that communicates with the gas meter 1 via the alarm device A2 of the master unit. The communication between the alarm device and the gas meter may be wired or wireless.
