Abstract:
To provide a prepaid system, a prepaid server and a gas meter in which a prepaid money amount is managed at a monitoring center side to improve convenience of a gas user.SOLUTION: A prepaid system 1 comprises: a gas meter 10; a monitoring center server; and a prepaid server. The prepaid server calculates a gas consumption amount used for a first time period on the basis of a meter reading value of the gas meter, and updates a prepaid money amount. When it is determined that a gas amount being usable using the updated prepaid money amount is lower than a setting value, the prepaid server transmits a warning determination value to the gas meter. When the warning determination value is received, the gas meter measures the gas consumption amount for a second time period being shorter than the first time period, and transmits a warning signal to the prepaid server when an integrated value of the gas consumption amount exceeds each warning determination value. The prepaid server transmits a residual amount alarm to a terminal device of a gas user who uses the gas meter.SELECTED DRAWING: Figure 1
