    Method for displaying the amount of power consumption in a television
    BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power consumption display method of a television having a power consumption display function, wherein the rated power consumption and the activation mode in the stand-by mode are not provided without a power consumption sensing means for calculating power consumption. Calculate the power consumption and power bill from the rated power consumption in TV on mode, duration of these modes, and charge per unit power, process various data based on this, and then display OSD (On Screen) in response to user demand. Display) The present invention relates to a power consumption display method of a television.
    Conventionally, since the television does not have a power consumption display function for informing the viewer of the power consumption according to the television, when the viewer wants to know the power consumption for watching the television, the television viewing time is recorded one by one and It was only possible to multiply the indicated rated power consumption.
    In order to solve this inconvenience, a television with a power consumption display function has emerged.
    The television with the power consumption display function described above includes power consumption sensing means for sensing power consumption based on at least the amount of current drawn through an AC power plug, as in Korean Utility Model Registration Publication No. 97-007542, and the power consumption detection. There is a power consumption display function television comprising power consumption calculating means for calculating an average power consumption based on a data value by the means and means for displaying the calculated value by the power consumption calculating means on a CRT.
    In addition, the power consumption display function of the Korean Utility Model Registration Publication No. 95-020121, which not only displays power consumption on a CRT, but also displays power consumption by date and year, as well as charges according to the amount of power consumed, as described above. There is a power consumption detection means for detecting the power consumption based on the amount of current drawn through the AC power plug, and calculates the power consumption based on the detection result by the power consumption detection means and stored in the charge storage means A database according to power consumption based on calculation means for calculating a usage fee based on unit fee data, calendar generation means for generating date and date data, power consumption calculated by the calculation means, and date and date data by the calendar generation means. Data processing means to create, save the charge per power consumption In the data input means and the data input means having a storage means, a selection key for selecting a data item desired by the viewer, an inquiry key for inquiring the total usage fee, and a numeric key for inputting the usage fee data per power consumption. And display means for visually displaying the selected item data.
    The television having the power consumption display function as described above has a problem in that the manufacturing cost of the television is increased by adding the power consumption sensing means for calculating power consumption as an essential component.
    In addition, it only calculates and accumulates the power consumption, and does not have the function of calculating and displaying the power consumption and power consumption accumulated for each of the standby mode / activation mode. There was also a problem that can not be recognized by the viewer that can not be ignored.
    Accordingly, the present invention has been sought for a method for calculating and displaying power consumption and total power consumption for each of the standby mode and the activation mode without the power consumption sensing means.
    DISCLOSURE OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and in a television having a power consumption display function, the rated power consumption in the standby mode and the activation mode without providing a power consumption sensing means for calculating the power consumption. The power consumption and power rates are calculated from the duration of each mode and the charge per unit power. Based on this, the accumulated power consumption or power charge is displayed on the screen in response to the user's request. The purpose is to provide a power consumption display method.

And a screen display process of reading the power rate from the storage means and outputting the screen as OSD characters. The operation and storage process includes: a mode determination step of determining whether the current television mode is a standby mode or an active mode; The calculation step for each mode that calculates the power consumption and power bill for each mode, and the accumulation and storage step for calculating and storing the cumulative power consumption and power bill for each month and month based on the calculated power consumption and power bill Comprising, the step of calculating the power consumption is rated power in the standby mode and the activation mode And the power in each mode, the average power consumption by the respective duration and multiplies the count it is characterized in that calculation.
    The above objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.
    Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
    1 is a block diagram of a television employed in accordance with the present invention, a microprocessor 10, EEPROM (Electrically Erasable and Programmable Read Only Memory) 20, tuner unit 30, image signal processing unit 40, OSD unit 50, a voice signal processing unit 60 is included.
    In the figure, the microprocessor 10 is a means for controlling the overall operation of the television by the key input means (key matrix of the remote control or front panel), not shown, and the power consumption and the power bill in the standby mode / activation mode. And accumulate and store the result in the EEPROM 20, and display the cumulative power consumption and the electric power bill calculated by the operation of the key input means on the screen for each month and year according to the viewer's selection.
    Therefore, the key input means employed in the television of the present invention should additionally be provided with a selection key so that the viewer can inquire the accumulated power consumption and / or power rate.
    On the other hand, the EEPROM 20 stores power consumption and power rates for each mode and year and day so far under the control of the microprocessor 10, and the viewer operates the key input means to adjust the power consumption and / or power rates. When inquiring, the microprocessor 10 outputs the corresponding data to the microprocessor 10 under the control of the microprocessor 10 so that the microprocessor 10 can display it on the screen.
    In the present invention, the EEPROM 20 is adopted so that the data calculated so far is not lost even when the power plug is completely unplugged.
    The tuner unit 30 outputs a broadcast signal received by being tuned to a channel corresponding to the control of the microprocessor 10, and the image signal processor 40 demodulates and broadcasts the broadcast signal applied from the tuner unit 30. By detecting and extracting the composite video signal, the extracted composite video signal is processed and displayed as a displayable signal.
    In addition, the OSD unit 50 may read a character font corresponding to the control of the microprocessor 10 to generate a character signal using the read character font, and apply the generated character signal from the image signal processor 40. It is combined with the video signal and output to a monitor not shown.
    The voice signal processing unit 60 detects and separates the voice signal from the broadcast signal applied from the tuner unit 30, processes the signal into a signal that can be output, and then amplifies and outputs the audio signal to a speaker (not shown).
    A detailed description will be given with reference to the flowcharts of FIGS. 2A and 2B attached to a power consumption display process according to a preferred embodiment of the present invention in a television having a power consumption display function having the above-described configuration.
    First, when power is supplied to the television, the microprocessor 10 supplies only the power if the current mode of the television is plugged in and the power switch is "on", i.e. in active mode (TV / AV mode). It is determined whether the standby mode is in operation (S100).
    In the standby mode, if the standby mode is determined, the standby time duration is counted, and the power consumption is calculated by multiplying the rated power consumption in the standby mode accurately measured at the time of television development as the average power consumption and multiplying the standby power duration by the average power consumption. The power rate is calculated by multiplying the power consumption and the charge per unit power (S110 and S130).
    On the other hand, in the activation mode (TV / AV mode), the activation mode duration is counted, and the power consumption is calculated by multiplying the average power consumption in the activation mode precisely measured at the time of television development by the average power consumption to calculate the power consumption. The power rate is calculated by multiplying the calculated power consumption and the charge per unit power (S120 and S130).
    In order to calculate the power consumption and the electricity bill, the values for the rated power consumption in the standby mode and the rated power consumption in the activation mode must be memorized in advance when the TV is manufactured. It is assumed that the viewer can directly input and store the information by using key input means (not shown).
    Subsequently, the power consumption and power charges for each mode are accumulated and the total power consumption and power charges are calculated using the calendar function provided by the television. And the process of storing is completed (S140).
    The above process is repeated at regular intervals only while power is being supplied.
    On the other hand, when the viewer operates the key input means (not shown) to inquire the current power consumption and power bill of the television at this time, the microprocessor 10 recognizes this and outputs the power consumption and power bill inquiry menu on the screen as OSD characters. In order to control the OSD unit 50.
    Accordingly, the OSD unit 50 reads a character font corresponding to a power consumption and power bill inquiry menu under the control of the microprocessor 10, and generates a character signal using the read character font. Is synthesized to an image signal applied from the image signal processor 40 and output to a monitor (not shown) to display a menu (S200, S210).
    When the viewer selects a desired item from the power consumption and power bill inquiry menu displayed on the screen (S220), the microprocessor 10 recognizes this and reads out the corresponding data item from the EEPROM 20, which is displayed on the screen as an OSD character. By controlling the OSD unit 50 so that the viewer can visually check a desired item, for example, the power consumption and / or power consumption on the day of the standby mode, or the accumulated power consumption and / or electricity consumption on the active mode up to now. It will be (S230).
    As described above, according to the present invention, since a separate power consumption detection means is not required to calculate power consumption, it is possible to reduce the manufacturing cost of the television. Since the power bill can be calculated, the viewer can recognize that the power consumption in the standby mode cannot be ignored, unlike when the power plug is completely unplugged, thereby inducing energy saving.
