Abstract

PROBLEM TO BE SOLVED: To actualize a data transfer method for a gas charging system which enables a gas meter or a network controller to securely operate continuously for 10 years only with its internal battery without being supplied from external electric power for the gas charging system which performs prepayment processing. SOLUTION: A managing center 1 which performs reception processing from gas consumers and the prepayment processing for subtracting a gas charge from a prepaid amount and the gas meter 7 which measures a gas flow rate to integrate the consumption of gas and hold its related information inside are connected by a communication network 5 and the network controller 6 which mediates in communication between the managing center 1 and gas meter 7; and the managing center 1 and gas meter 7 send and receive data to and from each other. The managing center 1 performs the prepayment processing by performing data transfer with the gas meter 7 twice in total, i.e., data transfer in money reception from the gas consumers and data transfer of remaining amount reaching information.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for collecting gas charges, and more particularly, to a method for collecting gas consumption from a gas meter that measures gas flow and accumulates gas usage, and uses the gas according to the state of the gas meter. In this case, the present invention relates to a data transfer method of a gas billing system for performing a prepaid process of subtracting the gas use price from the advance payment.

[0005] In the figure, a gas billing device 10 stores balance data of a prepayment, and sequentially sends a gas meter reading request command to the gas meter 7 via a communication network 5. In response to this, the gas meter 7 measures the gas flow rate and integrates the gas metering value obtained by integrating the gas usage, and
Send to 0. The gas billing device 10 receives this from the gas meter 7 and obtains a usage fee according to the usage from the received gas meter reading data. And the gas billing device 10
Subtracts this gas use price from the advance payment and checks sequentially whether the remaining amount of the advance payment becomes zero.

[0006] Due to such a data transfer method, the number of times of communication is extremely large. Although the gas meter 7 has a built-in battery for the purpose of being able to operate independently and continuously for about 10 years without power supply from the outside, the number of times of communication with the gas billing device 10 for data transfer is extremely large. In some cases, it is difficult to respond to the need for continuous operation for 10 years using only the built-in battery.

As another configuration example other than the above, there is a case where a network control device is provided, and the gas meter 7 communicates with the gas billing device 10 via the network control device. In this case, similarly to the gas meter 7, the network control device includes a battery for the purpose of being able to operate independently and continuously for about 10 years without power supply from the outside, but if the number of communications is extremely large, In some cases, it was difficult to operate continuously for ten years using only the built-in battery.

Therefore, in order to operate the gas meter 7 or the network control device continuously for 10 years reliably, a commercial power supply (for example, AC 100 V) may be used as a power supply, but only the built-in battery is used without receiving external power supply. Therefore, it does not meet the need for independent and continuous operation. (See Japanese Patent Application Laid-Open No. H11-132827).
