The battery capacity is estimated by calculating the battery consumption with, and the voltage abnormality determination means makes a determination based on both the battery consumption and the voltage drop signal from the voltage detection means. When a signal is detected, it can be determined that it is a transient erroneous signal. Therefore, it is possible to prevent the trouble that the normal time voltage is activated but the time measuring means is activated by an erroneous signal to shut off after a predetermined time to enter the recovery inhibition state, and consumes the time after turning on the battery power means and consumes the most battery capacity. The battery capacity estimation means calculates the battery consumption amount from the number of interruptions / returns of the interruption means, and if the battery consumption amount is within a predetermined value, even if the voltage detection means detects a voltage drop signal, the signal is output. By not driving the cutoff means without outputting to the time measurement means, it is possible to prevent the voltage drop abnormal state itself due to erroneous determination, and there is no possibility that the gas cannot be used due to erroneous interruption due to erroneous determination. Reliability is improved and usability is improved.

It may be erroneously determined as a decrease. If an erroneous determination is made, the time measuring means 16 starts the measurement, or if a predetermined time elapses after being left unattended, a shutoff signal is output to the shutoff means 3 to cause a low battery shutoff state and the recovery is prohibited. For example, when the resetting means 13 and the container reset switch for clearing the gas remaining amount counter value and the like are operated to set the battery voltage confirmation mode, the voltage of the battery power supply means 2 is confirmed again. As a result, if a normal voltage is detected, a voltage drop abnormality due to an erroneous determination is detected, and the voltage abnormality canceling means 1
Release with 8. That is, in the above voltage drop abnormal state, when a voltage confirmation operation instruction is received from the operation input means 19, the voltage detection means 15 is re-driven to confirm the voltage, and when a normal voltage is detected, the time measurement means is erroneously determined. The counting of 16 is stopped, the warning of the voltage drop by the notification means 17 is canceled, and if the recovery prohibition state due to the abnormal voltage decrease is canceled, the recovery acceptance prohibition is canceled to enable the recovery, and the gas use permission state is set. That is, by arbitrarily outputting the voltage confirmation instruction by the operation input means 19, the voltage determination can be performed again at an arbitrary time zone under the normal average environmental temperature as compared with the case where the voltage is detected under an abnormally low temperature, and It is possible to prevent erroneous determination of sex.

When it is detected and erroneously determined to be an abnormal voltage drop, a warning is displayed as an abnormal voltage, and the time measuring means 16 shuts off after counting a predetermined time and notifies the gas consumer and the gas supplier of replacement due to the abnormal voltage drop. The gas operator or the like can confirm the voltage by the operation input means 19. When the voltage confirmation instruction is output, the voltage detecting means 15 is driven, and if a normal voltage is detected by determining whether or not the voltage is low, it is determined again as an erroneous determination due to environmental factors, and the voltage of the informing means 17 decreases. When the warning display is reset, the operation of the time measuring means 16 is stopped, and the counting means is completed and the cutoff means 3 is operating, the return prohibition state of the return prohibition means 14 is released, and the consumer or gas business When a person performs a reset operation, the gas appliance can be used again.Therefore, it is necessary to reconfirm whether an erroneous determination of a voltage drop due to an environmental factor or the original voltage drop due to battery consumption due to some factor has occurred. Since the use of the gas appliance can be resumed by this, it is possible to prevent wasteful replacement of the gas shutoff device having a sufficient battery capacity, and the reliability and usability are significantly improved.

る。In this way, even though the battery capacity is sufficient, the supply voltage of the battery power supply means 2 of the gas cutoff device is erroneously determined as a low voltage below a predetermined value by the voltage detection means 15 due to environmental factors such as abnormal low temperature. When it is detected and erroneously determined to be an abnormal voltage drop, a warning is displayed as an abnormal voltage, and the time measuring means 16 shuts off after counting a predetermined time and notifies the gas consumer and the gas supplier of replacement due to the abnormal voltage drop. The gas utility or the like can confirm the voltage by the external communication means 20. When the communication means 21 receives and decodes the voltage confirmation request, the voltage detecting means 15 is driven, and if a normal voltage is detected by determining whether it is a low voltage or not, it is re-judged as an erroneous judgment due to environmental factors, etc. When the display of the voltage drop warning of 17 is reset, the operation of the time measuring means 16 is stopped, and when the counting means is completed and the shutoff means 3 is operating, the return prohibition state of the return prohibition means 14 is released, and the demand is restored. Since the gas appliance can be used again when the house or the gas operator restores the operation, whether the erroneous determination of the voltage drop due to environmental factors or the original voltage drop due to the battery consumption due to some factor,
Since it is possible to restart the use of the gas appliance by reconfirming from a remote place or at the site and performing a return operation in the case of an erroneous determination, it is possible to prevent wasteful replacement of the gas shutoff device having a sufficient battery capacity. Further, since the voltage reconfirmation operation can be performed remotely, the gas utility can reduce the number of dispatches, which greatly improves reliability and usability.

By communication from the external communication means 20 such as the setting device described in the embodiment or the communication device of the security center of the gas company,
Although the control means etc. are transmitted to the gas cutoff device and received by the communication means 21 to be decoded and the voltage is confirmed, even if the voltage confirmation communication message is received by the communication means 21 when the normal voltage is detected, the communication confirmation such as undefined response is confirmed. Unnecessary message is returned.

When the voltage confirmation communication message is received from the external communication means 20, the voltage detection means 15 is re-driven to check the voltage, and if the erroneous determination is made, the counting of the time measuring means 16 is stopped and the voltage by the notifying means 17 is applied. If the voltage drop warning is canceled and the recovery is prohibited due to an abnormal voltage drop, the recovery acceptance prohibition is canceled to enable recovery and the gas usage is enabled. That is, by outputting the voltage confirmation instruction through the communication unit 21, it is possible to perform the voltage determination again at an arbitrary time zone under the normal average environmental temperature as compared with the case where the voltage is detected under an abnormally low temperature.

ない。However, even if the external communication means 20 sends a voltage confirmation message to the communication means 21 when the voltage detection of the battery power supply means 2 is normal, it is necessary to drive the voltage detection means 15 many times. Since the battery capacity of the means 2 is wastefully consumed, the confirmation unnecessary message is returned to the external communication means 20 and the voltage detection means 15 is not driven. There is no problem even if the confirmation-unnecessary message is, for example, an undefined response message or the like, which is a returned power transmission message when setting is not possible.

い勝手が極めて向上する。In this way, when the battery capacity is sufficient and the voltage drop signal is not output from the voltage detection means 15, that is, when it is determined that the voltage is normal, the communication means 21 receives the voltage confirmation message. Also, if the voltage is normal, a confirmation unnecessary message is returned to prevent the voltage detection means 15 from being driven, and it is possible to prevent an accidental mistake of the gas utility and prevent unnecessary battery capacity from being consumed. The operability and usability are greatly improved.

Reference numeral 23 is a battery capacity estimating means, which is the elapsed time from when the battery power source means 2 is turned on, and the shutoff means 3
The battery capacity is estimated by calculating the battery consumption amount based on the number of times of interruption and the number of times of restoration and the current consumption of the interruption means 3. The voltage detection means 15A of the fourth embodiment monitors the supply voltage of the battery power supply means 2 and outputs a voltage drop signal when a low voltage below a predetermined value is detected, and the voltage drop abnormality determination means determines the voltage drop abnormality. 24 does. That is, when the battery consumption amount calculated by the battery capacity estimating means 23 is within the predetermined value, even if the voltage detecting means 15A detects the voltage drop signal, it is determined as an erroneous signal and output to the time measuring means 16. No, voltage detection means 1
Only when 5A detects the voltage drop signal and the battery consumption amount is equal to or more than the predetermined value, the voltage abnormality determination unit 24 determines that the voltage is abnormal and causes the time measuring unit 16 to output the voltage reduction signal.

A gas shutoff device is installed, and the flow rate detecting means 10 and the external equipment means 11 monitor the gas appliance usage state of the gas consumer. During the use, when the abnormality judging means 12 detects that the gas stove is being used for an abnormally long time, the interruption signal is output to the interruption means 3 to stop the gas supply. Under such a monitoring condition, the battery of the battery power supply means 2 is abnormally consumed for some reason and the battery voltage is lowered.
Is detected as a low voltage and the battery capacity is equal to or higher than a predetermined value by the voltage determining means 24, the recovery inhibiting means 14 is notified and the voltage detecting means 15A causes the time measuring means 16 to be notified.
To output a voltage drop signal. The notification means 17 displays a warning of a low voltage state by an LCD element, an LED element or the like.
Furthermore, the gas supplier will be notified of an abnormal voltage drop condition via a telephone line or the like.

る。The time measuring means 16 counts time by inputting the voltage drop signal and measures the usable time of the gas shutoff device after the voltage drop. When a predetermined time has been counted, the return signal from the return means 13 is put into the input prohibition state in the return prohibition means 14, and the cutoff output to the cutoff means 3 is performed.
By thus stopping the gas supply, the fact that the safe usable time of the gas shutoff device has elapsed is notified. Here, while the voltage drop signal is input and the time measuring means 16 is counting the time, the flow rate detecting means 10 and the external equipment means 11 detect the usage state of the gas appliance of the consumer, and the usage state is determined by the abnormality determining means 12. However, when an abnormal state is detected, the input of the return signal of the return prohibiting means 14 is immediately prohibited at that time, and the cutoff state is set. In other words, when the time measuring means 16 detects the voltage drop signal and the abnormality determining means 12 determines that there is an abnormality due to an abnormally high flow rate such as a gas hose disconnection for some reason during the time counting, the interruption means 3
In addition to the interruption output, the restoration prohibition means 14 is also notified of the interruption. Therefore, even if a return signal is input from the return means 13, the return is prohibited and the cutoff state is maintained.
Notify the customer and the gas supplier that the gas cannot be supplied unless the gas shutoff device itself is replaced via 7.

遮断されて復帰禁止状態になることはない。At this time, when the voltage detecting means 15 detects a voltage drop in the voltage of the battery power source means 2 under a weather environment such as a transient abnormal low temperature, the original battery capacity may be sufficient. Therefore, in the fourth embodiment, the battery capacity estimation means 23 calculates the battery consumption amount from the elapsed time from the start of turning on the battery power source means 2, the number of times of interruption of the interruption means 3 and the number of restorations, and the current consumption of the interruption means 3. Then, the remaining capacity of the battery is estimated, and if the battery consumption is within a predetermined value, the voltage drop signal from the voltage detection means 15A is determined to be an erroneous signal and is not output to the time measuring means 16. Therefore, the time measurement means 16 does not count the time, the voltage drop warning is displayed, or the voltage drop is interrupted and the recovery prohibition state does not occur due to an erroneous signal.

上している。In this way, the battery capacity estimating means 23 estimates that the battery capacity is sufficient at all times or at the time of outputting the voltage drop signal, and the voltage detecting means 15A detects the voltage drop due to the abnormal change of the environmental temperature. However, it is not output as an erroneous signal to the time measuring means 16, and the voltage abnormality determining means 24 outputs the voltage lowering signal only when it determines the voltage abnormality from both the voltage lowering signal and the battery capacity. Therefore,
Although the battery capacity is sufficient, it is possible to operate the time measuring means 16 by an erroneous determination and prevent unnecessary interruption such as erroneous interruption such as interruption after a lapse of time, and the customer can use gas appliances such as gas stoop. The gas is not cut off during heating and the gas cannot be used, improving reliability and improving usability.

使い勝手が向上する。As described above, according to the first aspect of the present invention, the battery power supply means for supplying power, the shutoff means for shutting off and restoring the gas medium, and the supply voltage of the battery power supply means are monitored. However, when a low voltage lower than a predetermined value is detected, the voltage detecting means determines that the voltage is abnormal, and a predetermined time is measured from the time when the voltage detecting means determines that the voltage is abnormal, and the cutoff signal is output when the predetermined time elapses. A time measuring means, a returning means for outputting a return signal for returning the shut-off means to a gas supply enabled state, and an input of the return signal is prohibited when the predetermined time has passed by the time measuring means, and the input is not prohibited. In this case, a recovery inhibiting means for outputting the recovery signal, an operation input means for outputting a drive signal to the voltage detecting means by an external operation, and a voltage detecting hand by the drive signal from the operation input means. Is driven and when the normal voltage is detected, the time measurement of the time measurement means is stopped, and the voltage abnormality canceling means for canceling the recovery prohibition state of the recovery prohibition means is provided. In this case, it is judged that the voltage drop is abnormal due to the detection that the supply voltage of the battery power source is a low voltage below a predetermined value, and it is in the recovery prohibition state after the lapse of a predetermined time. When a gas utility etc. performs a voltage confirmation operation, the voltage detection means is driven by a switch operation instruction to reconfirm whether the voltage has dropped due to environmental factors or the original voltage has dropped due to battery consumption, and a normal voltage is detected. , It is determined again that the battery capacity is sufficient, and the time measurement by the time measurement means is stopped. That because the gas usable state, even if the customer becomes time to gas unusable state is stopped gas by erroneous determination during the cooking gas appliance, if it is a normal voltage by the re-confirmation,
Since it is possible to return from the cutoff state, gas usage can be resumed and usability is improved.
