METHOD AND SYSTEM FOR CONFIRMING CONTRACT STATE OF FLAT-RATE POWER USAGE APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a contract state confirming method for a flat-rate power usage apparatus capable of easily and correctly confirming the contract state of the flat-rate power usage apparatus, and to provide a contract state confirming system thereof.

SOLUTION: The method comprises a step (S11) for receiving unique identification information to be transmitted from each flat-rate power usage apparatus by going round an area with the flat-rate power usage apparatuses installed therein; a step (S12) for determining existence of the flat-rate power usage apparatus not receiving the identification information though the contract is made; and a step (S13) for confirming a contract content concerning the flat-rate power usage apparatus when the flat-rate power usage apparatus not receiving the identification information though the contract is made exists. The method preferably includes a step (S15) for canceling the contract concerning the flat-rate power usage apparatus when the existence of the unused power usage apparatus is confirmed.
