Title:
GAS APPLIANCE JUDGING DEVICE AND GAS METER HAVING GAS APPLIANCE JUDGING FUNCTION
Document Type and Number:
Japanese Patent JP3819282
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To produce a gas appliance judging device capable of easily judging a using gas appliance from a detected gas flow rate.
SOLUTION: A gas appliance judging device comprises a flow rate pattern table in which partial flow patterns separating a series of gas flow rate patterns generated in company with burning control for a plurality of gas appliances is classified for every control step, an appliance table making correspondence between gas appliances and the combination of partial flow patterns, and an appliance judging table for extracting a partial flow rate pattern matching to the gas flow rate pattern detected in a gas supply line and extracting a gas appliance matching the combination of the extracted partial flow rate patterns from the appliance table. As a using gas appliance is judged from the gas flow rate variation during the use of the gas appliance in this invention, a concept of partial flow rate pattern separating a series of complicated gas flow rate variation for every burning control step is introduced.
