Recognition and application of electrical home users emissions measurement system using the same

The invention discloses an electrical appliance recognition method. The method is characterized in that: an electrical appliance is recognized according to a matching result of current characteristic parameter values. The invention further provides a household user carbon emission metering system applying the method. The metering system comprises a bus voltage sampling module, a bus current detection module, a phase detection module, a signal conditioning module, an amplitude detection module, an electrical appliance recognition module and a carbon metering module, wherein the bus voltage sampling module is connected with the input ends of the phase detection module, the signal conditioning module and the amplitude detection module respectively; the bus current detection module is connected with the input end of the signal conditioning module; the output ends of the phase detection module, the signal conditioning module and the amplitude detection module are connected with the input end of the electrical appliance recognition module; and the output end of the electrical appliance recognition module is connected with the carbon metering module. In the system, carbon emission is metered on the basis of accurate recognition of the electrical appliance, so that people are helped to set up the consciousness of energy saving, emission reduction and low-carbon consumption and correct incorrect power utilization habits.
