摘要： According to the present invention, mistaken detection of a gas leak can be prevented even when using an appliance which has been newly installed in a dwelling receiving a gas supply, and whereby a gas leak can be detected rapidly, efficiently and accurately. The characteristics extraction means 5 extracts characteristics of a gas flow including a combination of the instantaneous flow volume data and the instantaneous flow volume time differential value, on the basis of the data obtained by the flow volume measurement means 1, pressure measurement means 2, instantaneous flow volume time differential operation means 3 and pressure time differential operation means 4. The leak detection means 7 compares the characteristics data for respective types of gas appliance or for a gas leak registered in the storage means 6 with the characteristics extracted by the characteristics extraction means 5, and if a matching is not achieved, further judges whether there is a flow volume variation or nozzle variation, and whereby it judges whether there is a gas leak or whether an unregistered appliance is in use. If occurrence of a gas leak, the warning means 9 issues a warning. If an unregistered appliance is in use, the characteristics data forming the basis of the judgment is registered as a new characteristics data in the storage means 6 by the characteristics data registration means 8.

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.
