  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the present embodiment.

(Embodiment 1)
FIG. 1 is a block diagram of the system meter corresponding to an alarm device according to the first embodiment of the present invention, and FIG. 2 is a block diagram thereof.

  1 and 2, the alarm-compatible system meter includes an ultrasonic flow rate measuring unit 18 as a flow rate measuring unit that measures the flow rate of the gas flowing through the flow path 17, and a gas blocking unit that blocks the gas when an abnormality is detected. A fire alarm having a gas meter 21 having a shutoff valve 19 and a communication means 20 for communicating information with an external information detection means, a notification means 22 for detecting and notifying a fire, and a communication means 23 as an external communication means Detector 24, gas alarm device 27 having an external communication means 26 for detecting and informing a combustible fluid and a toxic fluid, and a concentration of carbon monoxide (hereinafter referred to as CO) to detect and notify. And a CO alarm device 30 having an external communication device 29, and information communication with at least one of the fire alarm device 24, the gas alarm device 27, and the CO alarm device 30. Te, identified by the identification means 31 of the alarm, a gas meter 21 is configured to include a treatment selection means 32 for selecting a treatment in accordance with the identification result. Here, 33 is a gas water heater, gas cooker, gas fan heater or other gas appliance connected to the flow path 17, 34 is a fire sensor, and 35 is an alarm control means.

  The operation and action of the alarm meter compatible system meter configured as described above will be described.

  A fire alarm 24 is installed in the house. If a fire occurs, the fire alarm 24 detects the fire and generates a notification sound from the notification means 22 of the fire alarm 24. . At this time, the communication means 23 of the fire alarm 24 sends a signal notifying the gas meter 21 of the occurrence of a fire. And the gas meter 21 can know that the fire has occurred in the house by identifying that it is a signal of the fire alarm device 24. As a result, the gas selection is performed by the cutoff valve 19 by the treatment selection means 32 of the gas meter 21 outputting a signal for blocking the gas.

  On the other hand, when the gas meter 21 transmits a fire occurrence signal to another alarm device, for example, the gas alarm device 27 or the CO alarm device 30, the gas alarm device 27 or the CO alarm device 30 also receives the notification means 25, A notification sound can be generated from 28.

  With such a configuration, when the fire alarm 24 detects a fire, the gas meter 21 cuts off the gas and first prevents the spread of damage. And by reporting to other alarm devices, the gas alarm device 27 and the CO alarm device 30 can also generate a warning sound, so that many alarm devices can notify the danger, such as evacuation of people and initial fire extinguishing. Therefore, safety can be improved and damage can be minimized.

In addition, although it demonstrated that the fire alarm 24 detected initially, it is the same also when the gas alarm 27 and the CO alarm 30 detect initially. An instruction designated for each alarm signal is communicated to the gas meter 21, and the treatment selection means 32 outputs a signal for shutting off the gas to the gas meter 21, thereby performing abnormal gas detection or CO detection. The gas can be shut off immediately, and a safety process with improved safety can be performed. In addition, although the fire alarm 24, the gas alarm 27, and the CO alarm 30 have been described, at least one of these alarms and the gas meter communicate information, Similar effects can be obtained.

  Furthermore, when the gas meter 21 receives an abnormal signal from the gas alarm device 27, it is possible to prevent an instantaneous stop of the gas and improve convenience by shutting off the gas after a lapse of a certain time after reception. . For example, in the case of malfunction of the gas alarm device 27 due to spray or the like, the abnormality detection of the gas alarm device is canceled in a short time, so that the malfunction of the alarm device can be determined by opening a certain time interval. By such an operation, it is possible to prevent erroneous gas blockage. In addition, although demonstrated with the gas alarm device, the same treatment is fully conceivable also in other alarm devices. In addition, it is desirable that the fixed time interval can be set arbitrarily, and is normally set between 1 minute and 10 minutes.

  When the signal from the CO alarm device 30 shown in FIG. 3 is received, the ultrasonic flow rate measuring means 18 of the gas meter 21 instantaneously determines whether or not the gas is used, and it is determined that the gas is being used. For example, by immediately shutting off the gas, the gas can be shut off immediately, and a security process with improved safety can be performed. By using the ultrasonic flow rate measuring means 18, it is possible to instantaneously discriminate even when a low flow rate gas is used, and to quickly shut off the gas. Here, 36 is a CO sensor.

  In addition, if gas is not used, the gas meter is instructed to increase the notification sound from the CO meter, and the volume adjusting means 37 that informs the resident is provided, so that an accident other than the occurrence of CO by the gas appliance is also warned. It is possible to perform security processing with improved safety. Again, since the ultrasonic flow rate measuring means 18 can be used to detect that no gas is flowing instantaneously, such a treatment can also be performed quickly, and an accident can be prevented from expanding.

  For example, when an automobile is left running in the garage on the first floor, the CO alarm device 30 installed on the second floor detects CO and communicates the information to the gas meter 21. And if it confirms that the gas meter 21 is not using gas, it will instruct | indicate to the CO alarm device from the gas meter 21 to make the alarm sound of the CO alarm device 30 loud. If you do this, people who live on the second floor will be more likely to notice the alarm, and even if the person on the second floor falls, people who live in the next room can make a louder sound. Can be rescued at an early stage, and can prevent accidents caused by poisoning with CO exhaust gas from automobiles. Although the CO alarm device has been described, a similar configuration can be considered for other alarm devices.

  Although the above description has been made using the ultrasonic flow rate measuring means, it is obvious that the same effect can be obtained with a flow rate measuring means that can measure other instantaneous flow rates. Further, the information communication between the gas meter and the alarm device has been mainly described. However, the same effect can be obtained by selecting the processing by communicating the information of the gas meter and the alarm device to the management center. And although it demonstrated by sound volume as alerting | reporting, displaying visually on the display part of a gas meter is also included. Moreover, although the description has been made with the configuration in which the treatment selecting means is attached to all the alarm devices, it may be configured to be attached to some of the alarm devices, or only on the gas meter side. In addition, although the communication means is illustrated by wireless transmission / reception, it is obvious that the same effect can be obtained even if it is configured by wire. In particular, a LAN or a telephone line can be used.

As described above, the alarm-compatible system meter according to the present invention includes at least one of a fire alarm provided with communication means, a gas alarm provided with communication means, and a CO alarm provided with communication means. By providing a gas meter provided with a communication means for information communication with the above alarm device, an identification means for identifying the signal of the alarm device, and a treatment selection means for the gas meter to select a treatment according to the identification result of the identification means. The gas can be shut off by the abnormality information of the gas meter and various alarm devices, and the safety can be improved.
