Hereinafter, a preferred embodiment of a break time warning device and a method of performing the same according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an embodiment of a break time warning device of a computer. When the video signal driver 10 receives a video signal from a video signal source, the blanking signal BLK is input from the on-screen display unit 12. The video signal output from the video signal driver 10 is connected to be input to the video signal output unit 14 while the color signal R provided from the on-screen display unit 12 is connected to one side of the video signal output unit 14. G, B) are connected to be input. And the output signal of the video signal output unit 14 is configured to be input to the monitor 16 and displayed.

In addition, the microcomputer 20, which is a control means operated by a key signal input according to the user's keyboard 18 operation, is connected to the power supply unit 22 to receive power and to supply power to all parts including each component not shown. It is connected to control the supply, and the horizontal synchronous signal (H-Sync) and the vertical synchronous signal (V-Sync) are input to mix these synchronous signals to output a composite synchronous signal or to determine the presence or absence of the synchronous signal. It is connected to input a control signal from the synchronization signal adjusting unit 24 for outputting the output signal, and is connected to output a switching control signal for controlling the operation of the speaker 26 to the transistor Q1, and performs a predetermined operation Data for performing is interfaced with the data stored in the memory 28 to operate.

Therefore, when the user operates the computer after setting the working time and the rest time to 'AA' and 'BB' arbitrarily, the microcomputer 20 performs the specific operation and displays the working time inside the city. Calculate with an uncounted counter. As compared with the time counted with reference to the data stored in the memory 28, when the work completion time reaches, the microcomputer 20 outputs a high level control signal to the transistor Q1 to conduct the voltage Vcc. It is applied to the speaker 26, and accordingly the speaker 26 outputs a predetermined sound.

Then, when the work is completed, according to the manufacturer's design, a control signal for displaying on the monitor 16 the characters on which the user can recognize the end of work on the monitor 16 from the microcomputer 20 to the on-screen display unit 12. The on-screen display unit 12 outputs the blanking signal BLK to the video signal driver 10 by referring to the horizontal blanking signal H-BLK and the horizontal blanking signal H-BLK. The output unit 14 outputs the color signals R, G, and B. Then, the video signal driver 10 to which a video signal is input from a video signal source (not shown) blanks and outputs the video signal at a position at which a character indicating the end of work time is to be displayed, and the output video signal is output from the video signal output unit ( Characters are inserted to the monitor 16 by the input color signals R, G, and B at the positions blanked at 14), and the monitor 16 displays the characters that the user can recognize.

After the user is warned for a predetermined time as a predetermined sound or text, the microcomputer 20 does not provide power to the monitor 16 to control the power supply 22 so that the user may rest.

A detailed operation procedure thereof will be described with reference to FIG. 2.

If the user sets the green mode to turn on the power in step S2 and automatically perform work and rest operations according to a preset bar in order to use the computer, the microcomputer 20 starts the operation initialized in step S4. Set the work accumulation time and the break accumulation time to '0', set the work end time to 'AA' arbitrarily, set the break end time to 'BB' arbitrarily, and then perform step (6). Time is incremented using a timer not shown.

In step S8, the microcomputer checks whether the accumulated job accumulation time is greater than or equal to 'AA' set as the job end time, and if the accumulation time of the job is less than 'AA', performs step S6 again, and if more than 'AA', step S10 ) To output the job completion message for a predetermined time. In this case, the work completion message includes output of a predetermined sound through the speaker 26 and a text display through the monitor 16. In order to output a predetermined sound through the speaker 26, a high level control signal is applied from the microcomputer 20 to the transistor Q1, and a character from the microcomputer 20 to the on-screen display unit 12 for character display. A control signal for generation is output. At this time, the state of the text displayed by the blanking signal BLK and the color signals R, G, and B output from the on-screen display unit 12 may be a job end time as shown in FIG. 3A.

At this time, in the next step S12, the microcomputer determines whether to continue the work. In this case, do you want to continue the work shown in FIG. If the user wants to continue working, as in (Y'N), press the uppercase letter Y provided by the keyboard, and press the uppercase letter N, provided by the keyboard, to stop the operation. If a key signal corresponding to the input signal is inputted, perform step S14 to reset the cumulative work time to '0', then perform step S6 again, and if a key signal against the uppercase N letter is inputted (step S14). S16) to output a message and a predetermined sound indicating that the break time. At this time, the method of outputting the predetermined sound and the message is the same as step S10, and the content of the displayed message is 10 minutes from now on as shown in FIG. 3b.

Then, after performing step S16, the microcomputer 20 does not perform the operation in step S18, and thus, performing step S20 while turning off the monitor power to prevent unnecessary energy loss. Increase time

In step S22, when the accumulated resting time reaches 'BB' or more, the microcomputer 20 performs step S24 to turn on the power of the monitor and then outputs a predetermined sound or a message indicating that the working time is shown in FIG. 3C. After outputting for a predetermined time, it is determined whether the user releases the green mode by performing step S26. If the user releases the green mode by the key operation, the operation is terminated, and if the operation is not terminated, the operation (S28) is performed to reset the accumulation time to '0' and then perform the operation (S14) again.

As such, by automatically counting the user's computer working time at the same time as the power turn-on to warn the user not to perform excessive work, the user can take a proper rest, thereby making the work more efficient.

As described above, according to the break time warning device and the method of performing the computer according to the present invention, when the user turns on the power for the computer work in the state of setting the end time and the break end time in advance, the user's computer automatically By counting working hours and outputting a warning message for proper work, the user can maximize efficiency in performing work using a computer.
