DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for settling electricity charges using a magnetic card or an IC card (hereinafter simply referred to as a recording card).

[Conventional technology and problems]

To explain the conventional method of settling electricity charges between an electricity supplier (electricity company) and a consumer, in Figure 2, electricity is transferred from the supplier (electricity company) 1 to the transmission line. Alternatively, it is supplied to each customer 3 via the distribution line 2. Load 32 of various electrical equipment, appliances, etc. of consumer 3
The amount of power consumed is calculated by an integrated power meter 31 and displayed in an integrated manner. Electricity charges are normally settled on a monthly basis. That is, the electric power company usually dispatches a meter reader to each customer to read the indicated value of the electricity meter 31 and calculate the amount of electricity used for the month, that is, read the meter. The meter reader notifies each customer of the meter reading results and submits them to the power company. From these meter reading results, the electric power company calculates the electricity bill for the month based on the contract type, the minimum charge for each contract type, the basic charge, and the unit price of electricity that is categorized according to usage. , bill each customer.

(If the electricity bill is more than a predetermined amount, the amount of electricity is also billed at the same time.) At this point, each consumer becomes obligated to pay the electricity company, and by paying the bill, liquidation is completed.

In this way, the electric power company that is the electricity supplier must perform meter reading, electricity bill calculation, and billing/collection operations in order to settle electricity charges.These operations are in addition to the electric power company's business of supplying electricity. Electric power companies spend a great deal of money and effort on these operations, even though they are secondary operations.

This invention was made in view of the above-mentioned circumstances, and its purpose is to provide an electricity bill settlement device using a recording card that can significantly reduce the workload of electricity bill settlements for electric power companies serving as power suppliers. There is a particular thing.

[Means for solving problems]

In order to solve the above-mentioned problems, the electricity bill settlement device using a recording card of the present invention is capable of reading and rewriting initial data on a recording card in which initial data representing a predetermined amount of money is recorded in advance. The power consumption by the card reader/writer and the customer's load is input from the power amount detection device, and the electricity charges to be charged to the customer are calculated by a predetermined program based on the contract type. The charge data is subtracted from the initial data to obtain balance data, the card reader/writer rewrites the initial data on the recording card with this balance data, and an alarm device is provided when the balance indicated by the balance data falls below a predetermined amount. and a control calculation unit that issues a command to operate the power receiving switch of the consumer and to open the power receiving switch of the consumer when the balance becomes zero or a predetermined negative amount.

[Effect]

When a consumer inserts a so-called prepaid recording card (magnetic card, IC card, etc.) on which the initial data representing the charge is recorded into the card reader/writer of his or her electricity bill payment device, the control The calculation unit reads the initial data, closes the power receiving switch, calculates the electricity bill according to the consumer's electricity consumption and contract type, and determines that the difference between the initial data amount and the electricity bill is less than a predetermined amount. When the difference reaches zero or a predetermined negative amount, a switch is opened to stop power supply.

(Embodiment) Hereinafter, an embodiment of the electricity bill settlement device using the recording card of the present invention will be described with reference to FIG.

The electricity bill settlement device 1 of this embodiment includes a card reader/writer 11 and a microcomputer 1 as a control calculation section.
2, an alarm device 13, and a display device 14. Electricity is supplied to each consumer such as a home or a factory to which this electricity bill settlement device 1 is installed via a power receiving switch 4 from the power transmission line 2, and various electrical appliances such as lighting equipment, refrigerators, and air conditioners etc. The power consumed by a load 6 consisting of equipment and appliances is calculated by a power detection device 5 such as an integrating wattmeter (watt hour meter).

In the electricity bill settlement device having the above configuration, when a consumer inserts a prepaid recording card C purchased in advance into the card insertion slot of the card reader/writer 11,
The microcomputer 12 is a card reader/writer 1
In addition to manually memorizing the initial data corresponding to the purchase price of the recording card C taken by the government in accordance with 1, the amount (or the corresponding frequency, etc.) is displayed on the display device 14, and the opening/closing for power reception is performed. The device 4 is closed to enable power supply to the load 6. The microcomputer 12 is
Built-in automatic calendar program with predetermined /ff
The indicated value of the power amount detecting device 5 is read and stored at the end of the period of M months (for example, I months) or at the designated settlement account.

As power is consumed by the consumer's load 6, the amount of power consumed is integrated and displayed on the power amount detection device 5. Of course, the power consumption may be sequentially fetched into the microcomputer 12 from the beginning of the settlement period 101 and stored. In this embodiment, the microcomputer 12 reads the indicated value of the power amount detection device 5 on a predetermined settlement day, subtracts the indicated value on the previous settlement day, and calculates the power consumption for that month. Then, the electricity bill for the month is calculated based on this amount of power consumption, the consumer's contract type, the minimum charge, and the basic charge, and the amount of electricity is added as necessary. Furthermore, the microcomputer 12 subtracts the charge data indicating the electricity charge amount calculated in this way from the above-mentioned initial data to obtain balance data indicating the difference, and obtains the initial data of the recording card (or If this is done, the balance data (as of the previous settlement date) is rewritten with this balance data, and the amount is displayed on the display device 14. Also, when the remaining amount reaches a predetermined amount, the LED
The alarm device 13 such as a (light-emitting diode) indicator light is activated and the customer is notified of this. When the balance becomes zero, the microcomputer 12 opens the switch 4 to prevent power from being supplied until a newly purchased recording card is inserted into the card reader/writer 11.

Note that the switch 4 may be opened when the remaining amount reaches a predetermined negative amount. In addition, if you want to calculate electricity charges only based on power consumption, microcomputer 1
