摘要:
A gas appliance judgment apparatus and method by which a type of gas appliance in use and the existence of a gas leak can be identified. In operation, noise is removed from measured instantaneous flow volume, whereupon the “length”, “initial flow volume” and “sequence of transited regions” of the variable portion of the flow volume and the “length”, “average value” and “gradient” of the flat portion of the flow volume are extracted. A rule having characteristics data which matches the characteristics of the variable portion and the flat portion of the flow volume is then searched, and points are added respectively for the type of gas appliance and for the existence of a gas leak. When the added points are not less than a previously established threshold value, then the type of gas appliance in use is determined, and appliance type information is output as a judgment result.
摘要:
According to the present invention, the type of gas appliance in use can be identified and a gas leak can be detected, efficiently and accurately. The flow volume data noise removal means 21 removes noise from the instantaneous flow volume data measured by the flow volume measurement means 11, and from the data after noise removal, the flow volume data object extraction means 22 extracts data on the variable portion and the flat portion of the flow volume. The gas flow characteristics extraction means 31 extracts the “length”, “initial flow volume” and “sequence of transited regions” of the variable portion of the flow volume and the “length”, “average value” and “gradient” of the flat portion of the flow volume. In the appliance judgment means 41, the rule match search and point addition means 43 searches a rule having characteristics data which matches the characteristics of the variable portion and the flat portion of the flow volume, and adds points respectively for the type of gas appliance and for the existence of a gas leak. When the added points are not less than a previously established threshold value, then the appliance in use determination means 44 determines that a gas appliance of that type is in use, and outputs appliance type information as a judgment result.
摘要:
A control device includes a diagnostic pulse signal generating section having an internal circuit that generates control data and generates diagnostic pulse data for diagnosing the operating terminal and diagnoses the function of the signal line and the operating terminal from the waveform of a feedback signal of the diagnostic pulse signal; a variable amplification circuit that multiplexes the diagnostic pulse signal on the control signal and sends the result to the operating terminal with a preset signal level; and a receiving circuit that receives the feedback signal and sends it to the internal circuit. The internal circuit comprises a correction pulse data generating section that corrects the diagnostic pulse data by correcting the rise time of the diagnostic pulse signal. Even if the length of the signal line is long, the diagnostic pulse signal reception can be achieved without expanding the pulse width of the diagnostic pulse signal.

A first arithmetic operator (11) includes a first modular arithmetic coding encoder (11b) for encoding a numeric data transmitted by a command from a central controller (31) into a modular arithmetic code, a first arithmetic operation processor (11a) using the numeric data as modular arithmetic coded as an input operand, for executing an arithmetic operation based on a command from the central controller (13), to provide an output in the form of a modular arithmetic code, and a first modular arithmetic code decoder (11c) for determining presence or absence of a bit error in the numeric data output from the first arithmetic operation processor, correcting the bit error, if detected any, to output a decoded numeric data.
