Rest charge alarm device of IC card prepaid electricity meter

The present invention relates to the remaining charge alarm device of the IC card prepaid electricity meter, especially when the prepaid charges stored by the IC card are deducted according to the electricity usage and remain below a certain amount. The IC card prepaid rate formula enables the user to recognize the charging time of the prepaid rate accurately, thereby preventing the power shortage from occurring in the home by missing the charging time of the electric charge. Residual charge alarm device of the electricity meter.

Until now, the existing integrated electricity meter, which measures and measures the electricity consumption per hour for a certain period by visual inspection of the meter reader, has been used in homes, offices, public buildings, and all facilities that use electricity. In the first generation electricity meter, the meter visits the meter installed in each home or business, and checks the difference from the power consumption to the time of the meter reading, that is, the usage every month or for a certain period of time. After payment, print out and send the invoice by mail, and the user takes the paper to the bank and pays the paper to complete the settlement of the supply and use results. It was very complicated and costly, such as sending a bill once.

In addition, the second generation as the share of the above-mentioned costs in power supply costs, such as problems such as home invasion and camouflage strength disguising the meter reader, labor shortage due to evasion of the meter reading, and increase in labor cost of the meter reader, has increased. The product, a remote meter reading meter, is being reviewed as a new metering method and applied in a limited way. However, the above-mentioned remote meter reading can reduce visitor's cost and labor cost of meter reader, but problems such as computerized processing of monthly usage, billing procedure, receivables and processing of late fees remain intact, especially power line, telephone line, wireless, etc. When operating in conjunction with gas and water meter that require electric line and communication line, cost increase factors such as server operation, communication equipment and operation cost burden of meter and kia remote meter reading sensor such as gas and water due to communication function for remote meter reading Because of this, both vendors and users were avoided.

In order to solve the above problems, a third generation IC card prepaid electricity meter as shown in FIGS. 1 and 2 is provided.

In the conventional IC card prepaid electricity meter, when a user visits a nearby bank or storage institution and pays a predetermined amount of electricity, the storage institution records the unique number, user ID, and prepaid rate of the electricity meter installed in the user's home. While issuing an IC card, a predetermined password is provided to the user, and at the same time, the prepaid fee and the password paid by the user are transmitted through the communication unit 104 of the electronic meter 10 embedded in the electricity meter. Save it to

In this state, when the user returns home and inserts the IC card into the card insertion hole 103a provided in the main body case 20, the card reader 103 reads information such as the prepaid fee and the user ID stored in the IC card. Compare with the dictionary information stored in the memory (102a, 102b) to confirm the match.

Then, when the user operates the keypad unit 108 provided in the main body case 20 and inputs a password notified from the receiving institution, the central control unit 101 confirms whether the password matches and displays the prepaid fee. At the same time as output to the display window 122, the prepaid fee is deducted in proportion to the electricity consumption.

Reference numeral 204 denotes a power input line, reference numeral 206 denotes an output line connected to a load side, and reference numeral 106 denotes an open / close switch.

On the other hand, the central control unit 101 drives the alarm buzzer 124 when the charge balance falls to a certain value after a predetermined time elapses so that the user charges the prepaid fee.

However, in the prior art, since the alarm buzzer 124 is used as a means of informing the charging time of the prepaid fee, the user who dwells indoors even though the alarm sound is output through the alarm buzzer is considered that most of the electricity meters are installed outdoors. It was very difficult to charge the prepaid charges at the correct time when the alarm buzzed, and if the prepaid charges were missed, the on / off switch 106 was automatically turned off when the prepaid charges were exhausted, and the electricity supply to the home was stopped. There was a problem that prevented us from living.

In particular, most of the office workers who live outside the time there is a problem that often miss the charging time of the prepaid charges do not hear the alarm buzzer.

Therefore, the present invention for solving the above problems is a means for alarming the charging time of the prepaid charges to the user's phone, PC and mobile phone when the prepaid charges stored by the IC card is deducted according to the electricity usage and remains below a certain amount. By configuring the system, the user can recognize the charging time of the prepaid charges accurately, thereby providing the remaining charge alarm device of the IC card prepaid electricity meter, which prevents the electricity shortage from occurring in the home by missing the charging time of the electric charges. Has its purpose.
