Simple display power for display {Display apparatus for power consumption rates}

The present invention relates to a simple power amount display device.

More specifically, by directly measuring and checking the power consumption, usage time, power bill, and power consumption of electric and electronic products used in homes and businesses, it is possible to immediately know the state of use of power as well as the energy use. The present invention relates to a simple power display device that can induce a sense of savings.

In general, where a small amount of electricity, such as a home or a company, uses electricity, an electricity meter is installed to measure the amount of electricity used.

When installing a power meter as described above, a power supply side (for example, a power supply supplied by an electricity supplier) (Korea Electric Power) applied to each home or office, and a load-side wire supplying electricity to each load such as a home or an office Should be connected to the electricity meter.

When the power consumption used by the load side is measured by the above-described electricity meter, a mechanical method or a single-phase method of counting a predetermined pulse signal generated through the dial rotation of the mechanical electricity meter and recording and displaying the power consumption by the central processing unit ( It is metered electronically to calculate the amount of power by applying voltage and current of single phase or three phase.

In this case, the unit displayed with the number is [WON] for power charge, [KWH] for power usage, [HOUR] for consumption time, and consumption. Power [KW].

The power charge, power usage, usage time, and power consumption displayed on the display unit 150 are sequentially displayed for a predetermined time (for example, 3 seconds) according to the display control signal 141 of the controller 140.

In addition, unlike the above description, any one data selected by the consumer among the power charge, the power usage, the use time, and the power consumption may be continuously displayed.

In addition, the above-described display unit 150 is usually composed of a liquid crystal display device (Liquid Crystal Display) in order to represent the number and the decimal point, any other element that can display the number may be used.

Next, the operation of the simple power amount display device according to the present invention configured as described above will be described in detail.

First, in order to check how much power various electrical and electronic products consume using the power amount display device 100, the consumer should combine the electrical and electronic products to be measured with the power amount display device 100.

For example, as shown in FIG. 4, the plug 210 of the refrigerator 200 is coupled to an outlet 180 formed on the bottom of the power display 100, and the plug 180 formed on the back of the power display 100. ) Is coupled to an outlet 300 to which a commercial AC power is applied.

As described above, when the coupling is completed and the commercial AC power is applied to the electrical and electronic products through the power display 100, the input current of the commercial AC power output from the plug 170 to the outlet 180 is converted into a current transformer ( It is detected through 110, and is converted into a DC voltage through the rectifying and amplifying unit 120 is applied to the comparison circuit unit 130.

Meanwhile, a triangular waveform 191 output from the basic waveform forming unit 190 is input to the comparison circuit unit 130 described above, and the triangular waveform 191 is distributed by the above-described DC voltage data 121 and distributed. The data 131, which is a rectangular waveform generated and generated, is input to the controller 140.

In this case, the triangular waveform 191 is divided into a maximum of 3000 steps by the DC voltage data 121, and the control unit 140 varies the measurement degree according to the number of steps described above. ) Is the highest point of measurement.

Then, the control unit 140 calculates the power charge, the power usage, the use time, the power consumption through the data 131 which is the above-described rectangular waveform.

As such, when the power charge, the power usage, the use time, and the power consumption are calculated by the controller 140, the display control signal 141 is displayed by the controller 140 to be displayed together with the unit of each item through the display unit 150 in real time. Is output.

Meanwhile, the controller 140 outputs the control signal 142 to generate a predetermined triangular waveform in the above-described basic waveform forming unit 190, and the above-described basic waveform forming unit 190 controls the above-mentioned control unit 140.

In this way, according to the display control signal 141 of the controller 140, the measured data may be displayed on the display unit 150 while sequentially displaying power rates, power usage, usage time, and power consumption (for example, For example, if more than four digits), the control unit 140 switches to the initial state and performs the re-measurement process.

As described above, while the power consumption is performed through the electrical and electronic products, a part of the display unit 150 is controlled to be turned on or blinking so that the consumer can easily recognize the power, and the consumer exchanges the power amount display device 100 with commercial use. When the power supply is disconnected from the outlet 300 and recombined, the current measurement data is reset so that the measurement and display can be made from the beginning. When measuring a current of about 5W or less, the power amount is not measured.

In addition, when a user inputs a reset signal through the key manipulation unit 200, all values stored in the control unit 140 are initialized, and the unit price of the charge stored in the control unit 140 is also increased. Or changed by the down key. At this time, the range of the price change price is 0 ~ 9999 won, the unit price pre-set in the control unit 140 is not erased until reset by the user.

Herein, the present invention has been described based on the fact that the commercial AC power applied to the electric power display device is 220V, but is not limited thereto. In addition, the same may be applied to the case of 110V.
