As shown in FIG. 1, a general digital clock includes a power supply 11 for supplying power required for each component block, an oscillator circuit 12 for generating and applying a reference clock, and a corresponding oscillator circuit 12. A division clock circuit 13 for dividing the clock applied from the circuit 60 and applying the divided clock, and a divided clock applied from the division circuit 12 as a 60-degree counter circuit, and counting the first clock CK1 and `. Second counter 14 for applying the first signal representing the second 'and the first clock CK1 applied from the second counter 14 as a 60-degree counter circuit counting the second clock (CK2) and' minute ' The third counter CK3 which counts the second counter CK2 applied from the minute counter 15 as a binary and twelfth counter circuit of AM and PM, ) And the hour counter 16 for applying the third signal representing the hour, and the month The true number of the counter circuit varies according to the month discriminating unit 17 which calculates the number of `days' for the sixth signal to be applied and applies the control signal, and the control signal applied from the corresponding month discriminating unit 17. A one counter 18 that counts the third clock CK3 applied from the counter 16 and applies a fourth signal indicating 'one' with the fourth clock CK4; A day clock 19 for counting a third clock CK3 applied from 16 and applying a fifth signal indicating 'day of the week'; and a fourth clock applied from the corresponding day counter 18 as a hexadecimal counter circuit. CK4) is counted to receive the signal from the wall counter 20 to apply the sixth signal, and the seconds, minutes, hours, days, months and days of the week counters 14 to 20 receive the seconds, minutes, Display circuit section 21 for switching between 'hour', 'day', 'month' and 'day', and the corresponding display by user's operation Controlling the display function of 'hour', 'day of the week', 'date', etc. of the part 21 and controlling the setting of the corresponding seconds, minutes, hours, days, months, and days of the week counters 14 to 20 It comprises a switch control unit 22.

Operation of the clock configured as described above is as follows.

Receiving power from the power supply unit 11, each component block performs an operation. First, the oscillation circuit unit 12 generates a reference clock and applies it to the division circuit unit 13, and the division circuit unit 13 is a corresponding oscillation circuit unit ( The clock applied from 12) is divided into 60 to generate a signal of normally 1 (Hz) and applied to the second counter 14.

Thus, the second counter 14, which is a 60-degree counter circuit, counts the divided clock applied from the corresponding division circuit unit 12, applies a first signal indicating 'second' to the display circuit unit 21, and counts 60 times. Each time, the first clock CK1 is applied to the minute counter 15.

The minute counter 15, which is a 60-degree counter circuit, counts the first clock CK1 applied from the second counter 14 to apply the second signal indicating 'minute' to the display circuit unit 21. The second clock CK2 is applied to the time counter 16 every 60 counts.

Then, the second counter applied from the minute counter 15, the hour counter 16, which is a counter circuit selectable from 12-hour digits with AM and PM indications, or 24-hour digits with no indications. (CK2) is counted to apply a third signal indicating 'hour' to the display circuit unit 21, and the third clock CK3 is applied to the work counter 18 and the day counter 19 each time it is counted 24 times. Is authorized.

In addition, the day counter 18 changes the essence of the counter circuit according to the control signal applied from the month discrimination unit 17 that calculates the number of days for the sixth signal representing the month. For example, if the current month is January, 31 digits will be counted up to 31, especially if it is February, then 28 or 29 digits will be counted up to 28 or 29 by calculation. A fourth signal indicating 'work' is applied to the display circuit unit 21 by counting the third clock CK3, and the fourth signal is counted every time the number 28 or 29 or the number 30 or 31 is counted according to the control signal. The clock CK4 is applied to the wall counter 20.

Then, the day counter 19, which is a seven-counter counter circuit, counts the third clock CK3 applied from the counter 16 at that time, and applies a fifth signal indicating the day of the week to the display circuit unit 21. The wall counter 20, which is a 12-degree counter circuit, counts the fourth clock CK4 applied from the corresponding day counter 18, and outputs a sixth signal indicating 'month' to the corresponding display circuit 21 and the month discrimination circuit 17. ) Is applied.

In addition, the display circuit unit 21 receives the first to sixth signals from the corresponding seconds, minutes, hours, days, months, and days of the week counters 14 to 20 to display the seconds, minutes, hours, The display is switched to 'day', 'month' and 'day', and the display functions such as 'time', 'day of the week', 'date', and the like are displayed differently according to the control of the switch control unit 22.

By the way, the clock has been developed to have a number of functions in addition to the function to inform the time in the configuration as described above, for example, the function of the alarm, the function of weather warning, the time difference of the world is input There are functions to display the time differently according to the country. In particular, recently, with the development of microchips, watches that can perform various functions according to the input of the switch control unit 22 using one corresponding chip have been continuously developed.

Meanwhile, the United States, Europe, and other countries use a summer time system that speeds up the hour by hour to take advantage of long daylight hours during summer, compared to countries that do not use the summer time system. Same as increased. Therefore, during the period in which the summer time system is applied, one hour must be advanced and one hour must be delayed to the original time zone after the corresponding time period. In the related art, the user directly operates the switch control unit 22 to control the time. Had to be reset.

As described above, in the conventional clock, when the summer time system is to be applied or released, the user needs to manually operate the clock to reset the time.

Automatic time correction device for the clock according to the present invention for solving the inconvenience as described above is to provide a user convenience by automatically applying or releasing the daylight saving time without the user directly operating the clock.

The present invention for achieving the above object is a first date setting counter for setting the application date of the daylight saving time according to the operation of the switch control unit; A second date setting counter for setting a release date of daylight saving time according to an operation of the switch control unit; A first hour setting counter for setting an application time of daylight saving time according to an operation of the switch control unit; A second time setting counter for setting a release time of the summer time according to an operation of the switch control unit; Read the application date set in the first date setting counter and the application time set in the first hour setting counter to read the day signal applied from the day counter, the month signal applied from the wall counter, and the hour signal applied from the hour counter.

Automatic time correction apparatus for a clock according to an embodiment of the present invention, in addition to the configuration of the conventional digital clock shown in Figure 1, as shown in Figure 2, the first date setting counter 31, the first comparison The circuit section 32, the second comparison circuit section 33, the second date setting counter 34, the first hour setting counter 25, the second hour setting counter 36, and the summer time control circuit section ( 37).

The first date setting counter 31 is the same counters as the day counter 18 and the wall counter 20 of FIG. 1, and an application date (month and day) to start the daylight saving time according to the operation of the switch control unit 22 of FIG. 1. Set).

The first comparison circuit 32 reads the application date set in the first date setting counter 31 and the application time set in the first hour setting counter 35 and is applied from the work counter 18. Compared to the one signal, the wall signal applied from the wall counter 20 and the hour signal applied from the hour counter 16 of FIG. 1, and if the same, the first comparison signal CS1 having a 'low' level is generated. .

The second comparison circuit 33 reads the release date set in the second date setting counter 34 and the release time set in the second time setting counter 36 and is applied from the work counter 18. Compared to the one signal, the wall signal applied from the wall counter 20 and the hour signal applied from the hour counter 16, the second comparison signal CS2 having a 'low' level is generated.

The second date setting counter 34 sets the release dates (months and days) to end the daylight saving time according to the operation of the switch controller 22 as counters identical to the day counter 18 and the wall counter 20. Leave it.

The first hour setting counter 35 is the same counter as the hour counter 16 and sets an application time at which the summer time system starts according to the operation of the switch control unit 22.

The second hour setting counter 36 is the same counter as the hour counter 16, and sets a release time for terminating the summer time according to the operation of the switch control unit 22.

The summer time control circuit unit 37 starts to perform an operation according to the first comparison signal CS1 having a low level applied from the first comparison circuit unit 32 to the hour signal of the hour counter 16. 1 'is increased and set, and' 1 'is decreased to the hour signal of the hour counter 16 according to the second comparison signal CS2 of the' low 'level applied from the second comparison circuit unit 33. After completing the operation, terminate the operation.

The operation of the automatic automatic time correction apparatus for a clock according to an embodiment of the present invention will be described as follows.

First, by further using two sets of counters having the same configuration as the day and month counters 18 and 20 shown in FIG. 1, that is, the first date setting counter 31 and the second date setting counter 34 In accordance with the operation of the switch control unit 22 shown in FIG. 1, the day setting 18 and the month counter 20 need to apply daylight saving time to the corresponding first date setting counter 31. The application date is set and the second date setting counter 34 sets the release date to release the daylight saving time, and the set application date and release date can be reset later or the power supply shown in FIG. As long as it does not turn off (11), it does not change. Further, the first hour setting counter 35 and the second hour setting counter 36, which are counters having the same configuration as the hour counter 16 shown in FIG. 1, are further used, and the corresponding hour counter 16 is also used. In the same way as to adjust the time of the first time setting counter 35, the application time to apply the daylight saving time is set, and the corresponding time setting of the second time setting counter 36 is set to release the time to release the daylight saving time However, the set application time and release time do not change as long as the corresponding times are not reset later or the power supply 11 is turned off.

In addition, the first comparison circuit unit 32 may include a day signal indicating the number of 'days' counted from the day counter 18, a month signal indicating the number of `months' counted from the wall counter 20, and the time counter ( 16, the time signal indicating the number of hours counted is applied, and the application date set in the first date setting counter 31 and the application time set in the first hour setting counter 35 are read. The first comparison signal CS1 is applied to the summer time control circuit unit 37 after comparison with the counted one signal, the month signal, and the hour signal. In addition, the second comparison circuit unit 32 receives the day signal, the month signal, and the hour signal from the day counter 18, the wall counter 20, and the hour counter 16, respectively, and the second date setting counter 34. The second comparison signal CS2 is compared with the corresponding day time signal, the month signal, and the hour signal after reading the release date set in the second time signal and the hour signal set in the second hour setting counter 36. It applies to the control circuit part 37.

Accordingly, the summer time control circuit unit 37 starts to perform an operation according to the first comparison signal CS1 having the 'low' level applied from the first comparison circuit unit 32, and thus the hour signal of the hour counter 16 is performed. Set a value of '1' to increase the value of '1' and decrease the value of '1' to the time signal of the hour counter 16 according to the second comparison signal CS2 of the 'low' level applied from the second comparison circuit part 33. After setting, finish the operation.

That is, for example, the application date is set to 'June 10' and the application time is set to '10 o 'in the first comparison circuit unit 32, and the release is performed in the second comparison circuit unit 34. Assuming that the date is set to 'September 10' and the release time is set to '15 o ', the following description will be given.

First, if the counted day signal, the month signal, and the hour signal are not the same as compared with the application date and the application time of 'June 10, 10 o'clock', the first comparison circuit unit 32 is configured as a 'high' level first. The first comparison signal CS1 is generated, and if it is the same, the first comparison signal CS1 having a 'low' level is generated and applied to the summer time control circuit 37, and the second comparison circuit 33 is the release date. And the release time of September 10 15:00 are compared to the counted day signal, the month signal and the hour signal to generate a second comparison signal CS2 of the 'high' level if it is not the same and 'low' if it is the same. The second comparison signal CS2 of the level is generated and applied to the summer time control circuit unit 37.

Accordingly, the summer time control circuit unit 37 does not perform an operation but detects a first comparison signal CS1 having a low level applied from the first comparison circuit unit 32 to perform an operation. By setting '10' of the counted hour signal, which is the output signal of the hour counter 16, to '11', the summer time can be applied by increasing '1'. In addition, the summer time control circuit unit 37 is operating and detects a second comparison signal CS2 having a low level applied from the second comparison circuit unit 33 to release the daylight saving time. The operation is terminated by setting '15 or 3 'of the hour signal of the hour counter 16 to '14 or 2' to decrease '1'.

In this way, it is set to 'June 10th 11am' which is increased by one hour to 'June 10th 10am' to apply the daylight saving time and one hour to 'September 10th 15h' when the summer time is released. It is set to 'September 10 at 14:00', so you can turn daylight saving on and off.

However, an important matter at this time is that after the summer time is released, the summer time control circuit unit 37 is applied from the first comparison circuit unit 32 until the first comparison signal CS1 of the next 'low' level is applied. It does not perform an action. That is, in other words, the summer time control circuit unit 37 performs an operation according to the first comparison signal CS1 of the 'low' level applied from the first comparison circuit unit 32 and the second comparison circuit unit 33. The operation is terminated after canceling the summer time according to the second comparison signal CS2 having the low level of the second comparison signal CS2 applied, and the next 'low' level is released from the second comparison circuit section 33 after the summer time is released. Even if the second comparison signal CS2 is applied, the operation is not performed.

By further using the two date setting counters 31 and 34, the two hour setting counters 35 and 36, the two comparison circuits 32 and 33 and the summer time control circuit 37 as described above, You can automatically turn on or off daylight saving time without the need to manually adjust the clock.

Alternatively, daylight saving time can also be applied to a clock that moves analogously with the second hand, minute hand, and hour hand, that is, the minute hand that is connected to and rotates from the second hand or minute hand instead of removing the summer time control circuit 37. Or a device capable of rotating the minute hand or the hour hand regardless of the second hand or the minute hand by separating the hour hand, and when the first comparison signal CS1 is applied from the first comparison circuit part 32, the minute hand or the second hand from the second hand or minute hand. The hour hand is separated to rotate the minute hand or hour hand for one hour of summer time. When the second comparison signal CS2 is applied from the second comparison circuit unit 33, the minute hand or hour hand is applied for one hour of the corresponding summer time. Reverse or stop the rotation.

At this time, the important point is to make it possible to perform within 60 seconds when rotating with the minute hand, and to perform within 60 minutes when rotating with the hour hand. When rotating with the hour hand, it should be compensated as much as the minute hand rotation so that the hour hand is connected again. In this way, it can be applied to watches that work analogously.

As described above, the application and release dates set in the two date setting counters and the application and release times set in the two hour setting counters according to the present invention are applied from the day, month and hour counters in two comparison circuits. According to the comparison signal generated in comparison with the month and hour signals, the summer time control circuit unit may provide the user with convenience by automatically applying or releasing the summer time system without the user's direct manipulation of the switch control unit.
