    • With a gas shutoff device in the related art, a non-uniform gas layer can be produced by mixing of a gas of a different type from the gas currently in use during a shift in the amount of heat or installation or replacement, and an unexpected flow rate may be detected due to a disruption in the propagation of ultrasonic waves, thereby causing an erroneous determination of a flow rate abnormality or a sensor abnormality. With the gas shutoff device according to the invention, a valve-closing timer section 14 starts to time based on a valve-closing signal which is output by the flow rate abnormality or the sensor abnormality, and outputs a valve-opening signal to a valve driving section 12 if a release input is accepted from outside within a setting time period. Thus, even when the non-uniform gas layer is produced by mixing the gas of a different type from the gas currently in use during the shift in the amount of heat or installation or replacement, an unexpected flow rate is detected due to the disruption in the propagation of ultrasonic waves, thereby causing the erroneous determination of the flow rate abnormality or the sensor abnormality, and the valve is closed, the erroneous determination is resolved and the gas is available again within a given time period.
    • 利用现有技术中的燃气切断装置,可以通过在热量或安装或更换的换挡期间将不同类型的气体与当前使用的气体混合而产生不均匀的气体层, 可以由于超声波的传播中断而检测出流量,从而导致流量异常或传感器异常的错误判定。 利用根据本发明的燃气切断装置,基于由流量异常或传感器异常输出的关闭信号,关闭计时器部14开始时间,并将阀开启信号输出到阀 如果在设定时间段内从外部接受释放输入,则驱动部分12。 因此,即使当通过在热量或安装或更换的换挡期间将不同类型的气体与当前正在使用的气体混合来生产非均匀气体层时,由于中断而检测到意外的流量 超声波的传播,从而导致流量异常或传感器异常的错误判定,并且阀关闭,错误判定被解决,并且气体在给定时间段内再次可用。

    • A convention appliance monitoring apparatus handles only the amount of gas used and security information for the case of a gas cutoff and can not address social needs for a desire to obtain information about influence (e.g., an amount of CO2 emission) of use of the gas combustion appliance on a terrestrial environment.Based on a gas appliance used by a client and a gas flow signal pertaining the gas appliance which are output from an appliance determination unit 2, CO2 emission data on the gas appliance stored in a CO2 emission data storage unit 3, and CO2 emission data which are to be compared with the gas appliance and stored in a comparative CO2 emission data storage unit 4, a CO2 emission calculation unit 5 calculates an amount of CO2 emission, an comparative amount of CO2 emission and a difference between the amount of CO2 emission and the comparative amount of CO2 emission. Accordingly, it is possible to determine the amount of CO2 emission produced by using the gas appliance and the difference between the amount of CO2 emission and the comparative amount of CO2 emission.
