The terms used in the present invention have been selected from general terms that are currently widely used as much as possible, but in certain cases, there are terms arbitrarily selected by the applicant. Therefore, its meaning should be understood.

Hereinafter, the technical configuration of the present invention will be described in detail with reference to preferred embodiments shown in the accompanying drawings.

However, the present invention is not limited to the embodiments described herein and may be embodied in other forms. Like reference numbers indicate like elements throughout the specification.

Accordingly, FIG. 1 is a configuration diagram for explaining the configuration of a remote power meter reading verification system according to an embodiment of the present invention.

The measurement unit 100 serves to measure the measurement factor of the measurement target S, and is not limited as long as it is a means capable of measuring the measurement factor, such as an ammeter or a voltmeter capable of measuring direct current or alternating current.

Here, the measurement factor may be the current, voltage, frequency, etc. of the measurement object (S).

Here, the measurement target (S) is not limited as long as it is a means for producing, consuming or storing electricity such as door locks, lighting, heating, home appliances (washing machine, refrigerator, air conditioner, TV cleaner, etc.).

In addition, when the measurement target (S) is plural, the measurement unit 100 may be provided in a number corresponding to the measurement target (S).

The sensor unit 200 is provided on a wire connecting the measurement target S and the measurement unit 100, and transmits a signal transmitted from the measurement target S to the measurement unit 100 as a first information signal ( change to a).

Here, the first information signal (a) is preferably an analog signal, and the sensor unit 200 is preferably connected to the central processing unit 400 to be described later by wire.

This is to prevent the first information signal (a) transmitted to the central processing unit 400 from being distorted.

The output unit 300 converts the measurement factor measured by the measurement unit 100 into a second information signal (b) and outputs it.

Here, the second information signal (b) may be a digital signal, and may be output to a display so that a user or management company can check it.

In addition, the output unit 300 can be connected to the central processing unit 400 wirelessly or wired, and when connected wirelessly, it can be connected in various ways such as Bluetooth, WIFI, LORA, 3G, 4G, 5G.

The central processing unit 400 receives the first information signal (a) from the sensor unit 200 and receives the second information signal (b) from the output unit 300, and transmits the information signals (a, By comparing b), it is determined whether there is an abnormality between the measuring unit 100 and the second information signal (b), and the user's power usage pattern is analyzed based on the second information signal (b) determined to have no abnormality, and Calculate the optimal information value for power cost reduction.

More specifically, the measured value verification unit 410 receives the first information signal (a), which is an analog signal, from the sensor unit 200, and receives the second information signal (b), which is a digital signal, from the output unit 300. It is possible to determine whether or not the second information signal (b) is abnormal by receiving and determining whether the second information signal (b) is within the error range ±5 to 10% of the first information signal (a).

By comparing the signal (b) and determining whether there is an abnormality, it is possible to determine whether the measuring unit 100 has an abnormality.

For example, when the measurement unit 100 is out of order, the first information signal (a) has no abnormality, but the second information signal (b) disappears, so that the failure of the measurement unit 100 can be quickly determined.

As another example, the measured value verification unit 410 may be used when the measurement factor measured by the measurement unit 100 gradually decreases over time or when the measurement factor measured by the measurement unit is constantly repeated over time. In various cases, such as, the first information signal (a) and the second information signal (b) are compared to verify whether or not the second information signal (b) has an abnormality.

In addition, the AI reduction analysis unit 430 uses AI-based analysis technology to apply the differential power rate according to the situation to the user's power usage pattern analyzed by the AI pattern analysis unit 420, thereby reducing the user's power rate. Calculate the conditions for savings.

Here, the differential power rate includes various rate systems, such as a fixed rate system with a constant rate and a time-of-day rate system, a seasonal rate system, a peak rate system, and a real-time rate system that charge differently according to time zones, and may change according to the user's circumstances.

More specifically, the AI reduction analysis unit 430 learns the power rate to which the differential power rate is applied within the user's power use pattern for the use of the measurement target (S) calculated through the AI pattern analysis unit 420 And, by comparing the power rates under the condition where the cheapest differential power rate is applied, and calculating the optimal condition among the user's power use patterns in the use of the measurement target (S), the user can reduce power use conditions and electricity rates.

For example, when the power usage pattern analyzed by the AI pattern analysis unit 420 for the measurement target (S), which is a washing machine, is Saturday 9:00 to 12:00 or Tuesday 20:00 to 22:00, the AI reduction analysis unit 430 learns the electricity rate when using the user's measurement target (S).

Afterwards, when the saving analysis unit 430 analyzes that it is the cheapest from 20:00 PM on weekdays to 8:00 PM the next day, the AI reduction analysis unit 430 measures the electricity price from 20:00 PM on weekdays to 8:00 PM the next day. Use of (S) is provided as the first condition, and use of the measurement target (S) from 20:00 pm to 22:00 pm on Tuesday, which is within the user's power use pattern, may be provided as the second condition.
