As shown therein, a power supply unit 10 for converting the power input through the connector J1 into a setting level to provide driving power to each device; A function selector 20 having a plurality of operation switches SW1-SW3 for setting the relay operation time and function; The microprocessor 30 which operates with the power supplied to the power supply unit 10, generates a relay control signal according to a function input by searching the function selection unit 20, and simultaneously generates a control time display control signal with a specified time and an elapsed time. Wow ; A relay control signal generator 40 generating a driving control signal of the relay according to the relay control signal generated by the microprocessor 30; In accordance with the designated time and elapsed time display control signal generated by the microprocessor 30, the set time or the relay operation progress time is displayed, and at the same time, the designation / elapsed time display unit 50 is configured to display the state of the device.

In the above description, the power supply unit 10 includes a connector J1 for receiving power, a bridge diode DB1 for full-wave rectifying power supplied through the connector J1, and a direct current output from the bridge diode DB1. It consists of a constant voltage diode (ZD1) for making the voltage at a constant level, and a smoothing capacitor (C4) for smoothing the constant voltage produced by the constant voltage diode (ZD1) to supply to each part of the device.

In addition, the function selector 20 includes an operation switch SW1 for generating set and reset signals, a digit switch SW2 for resetting a time, and an up switch SW3 for adjusting a time when resetting a time. It consisted of

In addition, the relay control signal generator 40 includes switching elements Q1 and Q2 for generating a positive (+) and a negative (−) signal according to the relay control signal generated by the microprocessor 30. .

In addition, the designation / elapsed time display unit 50 includes two seven segments 51 and 52 for digitally displaying the designated time and the elapsed time according to the designated and elapsed time display control signals output from the microprocessor 30. And first to third light emitting diodes LED1 to LED3 which display an on / off time operation state and a set / reset state according to a display control signal output from the microprocessor 30.

Referring to the accompanying drawings, the operation of the digital dual timer device according to the present invention configured as described above is as follows.

First, the power supply unit 10 performs a full-wave rectification of the power input through the connector J1 to the bridge diode DB1 to make a DC voltage, and the DC voltage ZD1 is a constant voltage level (constant voltage). It is made to output, and smoothing capacitor (C4) smoothes the constant voltage and supplies it to each part of the device.

When the driving power is supplied to the device by the power supply unit 10 as described above, the microprocessor 30 performs the initialization operation of the internal port, and when the initialization operation is completed, the microprocessor 30 scans the function selection unit 20 to operate the switch SW1. It is determined whether or not SW3) is operated.

At this time, when the user presses the operation switch SW1 which is the set and reset switch to correct the time set previously, the microprocessor 30 stops the progress of the timer, and at the same time, in the designation / elapsed time display unit 50. The set display light emitting diode LED3 flashes.

Thereafter, when the user presses the digit switch SW2 while the set display light emitting diode LED3 is blinking, the on-time light emitting diode in the designation / elapsed time display unit 50 is controlled by the microprocessor 30 described above. The LED1) emits light, and at the same time, the on-time is displayed in the seven segments 51 and 52, and the number of digits of the day blinks.

Next, when the user presses the up switch SW3 once, the number of the place of the flashing day is changed to a number added with 1 to the previous number, wherein the up switch SW3 is pressed continuously. The digits of digit are displayed by adding one by one.

When the adjustment of the number of digits is completed by such a process, the number of the tens digit blinks when the digit switch SW2 is pressed again to adjust the number of tens digit next. Here, the number control of the tens digit is also set in the same way as the number control of the ones digit.

Here, the time displayed on the seven segments 51 and 52 can be set from 00 seconds to 99 seconds when the second unit is set through the function selection unit 20, and from 00 minutes to 99 seconds when the minute unit is set. Up to minutes can be set, and even from 0 to 99 hours can be set.

The above method is a time setting for the on time, and when the digit switch SW2 is pressed again after the on time time setting is completed, the off-time light emitting diode LED2 in the designation / elapsed time display unit 50 emits light. As described above, the number of one digit of the seven segments 51 and 52 flashes.

Then, the off time time setting is also performed in the same manner as the above-described on time time setting to set the off time.

When the time setting is completed in this way, when the set / restart switch SW1 is pressed at the time at which the timer is to operate, the timer proceeds to the set time zone.

Here, when the on-timer is in progress, the set on-time is decremented in reverse, and the elapsed time is displayed on the seven segments 51 and 52, and even when the off-timer is in progress, the set-off time is decremented inversely and the seven-segment 51 is reversed. Is displayed as elapsed time.

On the other hand, when the start key is pressed while the on time / off time is set as described above, the microprocessor 30 selectively controls the switching elements Q1 and Q2 in the relay control signal generator 40 to control the relay. Control to output the signal.

That is, when both the on time and the off time are set, the relay control signal generator 40 outputs + 5V as a relay control signal during the on time by the control of the microprocessor 30. On the other hand, the relay control signal is output at 0 V during off time.

If only the on time is set and only the off time is not set, the relay control signal generator 40 outputs a + 5V as the relay control signal at the on time, and the set and restart are set at the off time only. When the switch SW1 is operated, + 5V is output as the relay control signal, and when the off time is reached, the output of the relay control signal is cut off.

If both the on time and the off time are not set, the set light emitting diode LED3 in the designation / elapsed time display unit 50 blinks to request the user to set the on time or the off time. In the elapsed time display unit 50, the on-time light emitting diode LED1 or the off-time light emitting diode LED2 emits light in accordance with a state in which the dual timer is operated by the on timer or the off timer.

In the present invention, the relay control signal generation unit 40 has been described to control only the relay as a main point, the application of the operating characteristics of the present invention as described above can easily operate the photo-triac or other optical elements.

As described in detail above, the present invention has an effect of reducing the volume of equipment by changing the existing digital timer to a digital dual timer using an EPYROM type processor.

In addition, it is easy to manage and supervise the set time and the running time by converting to the digital dual timer.

In addition, by converting to a digital dual timer, the range of use and application is widened, so that the timer can be effectively and efficiently used.

The present invention relates to a digital dual timer (DGITAL DUAL TIMER), in particular to convert the existing digital timer into a digital dual timer to facilitate the management and supervision of the set time progress time, as well as to expand the range of use and application of the timer effectively It relates to a digital dual timer device to be used as.
