Title:
ガス器具判別装置およびガス遮断装置
Document Type and Number:
Japanese Patent JP4032944
Kind Code:
B2
Abstract:
PURPOSE: A gas appliance discriminating device and a gas cut-off device are provided to specify a used gas appliance by suing processing a usage state of the gas appliance and power consumption amount data. CONSTITUTION: A gas appliance discriminating device includes a gas flow detection part(11), a tap water consumption detection part(12), and an electric power consumption detection part(13). The gas flow detection part(11) detects a gas flow rate. The tap water consumption detection part(12) is connected to a water meter and detects water consumption amount. The electric power consumption detection part(13) is connected to a power meter and detects power consumption amount. The gas appliance discriminating device determines a type of a gas appliance by comparing the gas flow rate detected by the gas flow detection part(11), the water consumption amount detected by the tap water consumption detection part(12), and the power consumption amount detected by the electric power consumption detection part(13) with a stored gas flow rate stored, a stored water consumption amount, and a stored power consumption amount.
