<P>PROBLEM TO BE SOLVED: To provide a gas appliance decision device that learns an oscillatory waveform of each type of a gas appliance in a micro time to decide the type of the gas appliance in a short time, and to provide a learning method of the device. <P>SOLUTION: The gas appliance decision device 50 includes: a short term decision unit 53a that decides a type of the used gas appliance 10 based on the comparison of an acquisition data consisting of at least one of the oscillatory waveform and a processed data of the oscillatory waveform acquired in a micro time from the change time of at least one of a gas flow rate and a gas pressure, with a stored reference data; a long term decision unit 53b that decides a type of the used gas appliance 10 from a gas flow-rate change transition pattern which is acquired in a time longer than the micro time, when the reference data is not stored and the type of the used gas appliance 10 is not decided by the short term decision unit 53a; and a learning unit 53c that calculates a reference data on the basis of the acquisition data acquired by the short term decision unit 53a and then causes the reference data to be stored, when the type of the used gas appliance 10 is decided by the long term decision unit 53b. <P>COPYRIGHT: (C)2012,JPO&INPIT |
