Claim Text:
1. A detection method for detecting an appliance, comprising: selectively providing a first test load to connect with the appliance or providing a first test signal to the appliance; detecting a first voltage/current value of the appliance when the appliance is connected with the first test load or when the appliance receives the first test signal; generating a first voltage/current signature data according to the first voltage/current value; comparing the first voltage/current signature data with a plurality of signature data so as to generate a comparison result data; identifying a type of the appliance according to the comparison result data; selectively providing a second test load to connect with the appliance or providing a second test signal to the appliance when the type of the appliance is unable to be identified according to the first voltage/current signature data; generating a second voltage/current signature data according to a second voltage/current value of the appliance when the appliance is connected with the second test load or when the appliance receives the second test signal; and identifying the type of the appliance according to the second voltage/current signature data.
