BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic timer device using a microprocessor, and in particular, accurate time control in seconds is possible, and accordingly, various power supply opening and closing control functions are provided. Power ON, OFF, ON-OFF, OFF-ON, Repeat, and four functions by the time value set accordingly. The present invention relates to an electronic clock power supply timer device that allows any combination of functions to be controlled at one time.

Various types of timers have been developed and used in the past, but mechanical timers have a simple operation that turns on when a certain time elapses after manual operation or, conversely, turns off a contact after a certain time, In the case of a mechanical timer, the maximum charging time is set, which makes it difficult to continuously operate the timer.

In addition, various timer devices used in general household products are kept "on" during the time setting, and are "off" when the setting time is reached. On the contrary, when the setting time is reached in the "off" state, In many cases, the "on" state is continuously maintained or "on" at the first setting time of the "off" state and "off" at the second setting time.

These timers are generally embedded in home appliances and have been used in various ways while providing a very funky function to the user. However, the above-described timers are simple in their functions, and most of them cannot control the power switching time arbitrarily. There is a limiting factor in use, which is impossible because it is embedded in the product, which can only give a timer function to a specific product.

The present invention devised to solve the above problems has all the functions of a general digital electronic clock and the user needs to connect a control device (electrical product) to a power outlet 7 installed on the back of the clock of the present invention. By performing the power opening and closing function at the time set by the operation of the key board 5 installed on the front of the clock, the power can be arbitrarily adjusted by supplying or cutting off the power of the controlled device (electronic product), As well as the conventional simple function, it is possible to perform repeated power on and off at any time and to repeat and turn on and off for a specific time, maximizing convenience for the user and minimizing waste of power and all energy. It is an object of the present invention to use effectively.

Hereinafter, the configuration of the present invention with reference to the accompanying drawings in detail.

1A, 1B, and 1C, a microprocessor (2) is connected to the power supply unit (1), and the input / output ports (I / O ports) of the microprocessor are respectively. Operation mode display unit with time display section 3, time set (TS), on mode (ON), off mode (OFF), program mode (PRO), repeat mode (RPT), and on / off mode (ON / OFF) (4) Key board consisting of PROG, PROG, Slow Set Key (SS), Fast Set Key (FS), Clear Key (CLR), Current Time Set (TS) and Enter Key (ENT). -The board (5) and the relay (RELAY) 6 is connected, and the outlet 7 to which power is applied by the operation of the relay 6 is coupled to the relay 6 on the secondary side.

Looking at the operation and effects of the present invention made of the above configuration in detail by the accompanying drawings as follows.

In FIG. 1, when the AC power source (100 / 200VAC) is applied to the input power cord, the power supply unit 1 generates a DC power supply (5VDC) necessary for the operation of the electronic clock and the timer circuit to the microprocessor 2. A battery back-up 1 'is provided to apply power and cope with a power failure, and the time display unit 3 displays the current time and operation time of the timer using a display (FND or LCD). Key-board (5) has six key switches, the program key (PROG) to set the operation mode, the slow set key (SS) and fast set key (FS) It is used to set the time in the relevant mode.Clear key (CLR) is used to delete the set time.Enter key (ENT) indicates the setting completion and current time set key (TS) sets the current time of the electronic clock. When used.

The calculation of time is processed by software using the Interrupt function in the microprocessor 2 to count the frequency by the crystal oscillator 8 and to supply and cut off the output power outlet 7 as shown in FIG. Acts to be determined by the contact interruption of the relay 6 driven by the power transistor Q.

In addition, the oscillation frequency by the crystal oscillator 8 (X-TAL) that all functions such as mode setting, time setting, present time display, relay start, etc. are processed by the software of the microprocessor 2 and oscillates at a predetermined interval for this purpose. Is to generate the hardware interrupt function in the frequency counter.

The selection and operation principle of each timer function described above will be described in more detail based on the accompanying drawings with software.

2 to 4, when the power is initially applied, it initializes the necessary data structures and hardware (step 101), and then performs an interrupt function from this time, and initially operates in the present time display mode TS. do. The operation mode is changed by the program key PROG of the key board 5, and if the current time is set, set the current time display mode TS (step 102), and then set the slow set key (SS) and the fast set key. By using (FS) to perform the operation to display the current time on the time display unit 3, it can be seen that it is similar to the existing electronic clock, the usual timer is to perform the same function as the normal clock. .

Next, each mode which can be possessed by the program PROG is explained as follows.

The first is the ON time mode. This mode is the flow chart shown in FIGS. 3A and 3B. When the "on" time pointer is set (step 201) by the mode data change (step 105), the corresponding lamp ( ON mode is turned ON (step 202). After changing the "ON" time data (step 203) to a certain time (θt) and leaving the program with the Enter key (ENT), the corresponding lamp (ON mode) ) Is turned off (step 205), and the output power of the outlet 7 remains OFF from the current time as shown in the time chart shown in FIG. This mode is to turn on the power and get the output.

Secondly, in regard to the OFF time mode, the operation of this mode is similar to the ON mode described above, except that a timer that sends an output from the current time, such as the time chart shown in FIG. When the time set to OFF mode, i.e., t is reached, the timer output is interrupted and the controlled device is turned off.

Thirdly, it is ON-OFF time mode, which sets two times (step 403) and (step 408) in two modes, on time mode and off time mode. When it is small, as shown in the time chart in FIG.

Fourth is the OFF-ON time mode. In this mode, the output power is turned off during the time t _{6 when} the output power is turned on in the third mode description, that is, when the relay (RELAY) 6 is closed. (Diagram 2d)

Fifthly, in the Rep time mode, this mode is used to continuously repeat the on-off of the output power. In this case, there is no need to set the off time separately. The operation is performed by setting two times (step 503) and (step 508) of the cycle (RPT) and the time chart shown in FIGS. 2e and 2f, and the cycle (RPT) is a time to repeat , θH time and ON-RPO is the time interval that the power is output in the repetition period (RPT). This ON-RPO points out that performing the repeat mode directly from the current time is the next and next point.

That is, this mode is a mode in which the on-off period is repeated as long as? H time in the period of? H time, and the period is repeated repeatedly.

The sixth is the ON / Rep time mode. The fifth mode is used when you want the ON / Rep to be repeated after a certain time, that is, the αH time. The repeat mode is executed (step 206) by setting three times of the time mode set (item 1) and the repetition time mode set (item 5), and the timer stops output power until the on time, i.e., the αH time elapses. The repetitive mode is performed from the on-mode setting time θt while being kept off (Fig. 2g).

The seventh is the OFF / Rep time mode, which is similar to the sixth mode described, but performs the repetitive mode only for the time set to the off mode, that is, βH time, and turns the output power from θt time to γH time. The mode to be turned off is to operate contrary to the sixth mode described (Figure 2h).

Eighth, there is an ON-OFF / Rep time mode, which operates in two modes (step 902) and (step 903) depending on the magnitude of the on time and the off time. Time setting), the repetition mode (βH time) and the off mode (γH time) are set four times, and the repetitive mode which turns on / off the power for a specific time (βH time) is a mode (step 411).

If the on time is less than the off time, the power is kept off from the current time and the repeat mode is executed from the on time (Fig. 2i), otherwise the repeat mode is performed from the current time. The output power remains off until the on-time repeats to the repeat mode (Fig. 2j).

Such time setting, mode selection, and display time pointer conversion are performed in the main program of the software (Figs. 3a, 3b, 3c, 3d, 3e, 3f, 3g, and 3h). , FIG. 3i). If an error occurs during time setting, all time data of the current mode can be deleted using the clear (CLR) key. Each mode and the present performing operation display can be seen by the user as the lighting state of the light emitting diode (LED) in the operation mode display unit 4, the driving state, time calculation and comparison of the relay 6, the operation mode display unit 4 The operation state of the light emitting diode (LED) control and time display section 3 is performed in the interrupt program (FIGS. 5a, 5b, 5c, 5d, 5e). In other words, it can be seen from the flowchart (Fig. 5A) that the interception is usually performed in hardware.

When the control mode of the relay according to the mode selection of the present invention is described in detail, the control mode of the relay varies depending on which type of mode is selected in FIG. 5B (step 701 to step 704). The repetitive control (step 705) described above is performed, and in the on-off mode, the step of comparing the two time values is performed in the microprocessor 2, but if the off time is larger than the on time (step 708). When the on time mode is larger than the current time, that is, when the current time has not yet reached the relay on time stored in the timer, the relay is turned off (step 710). In 7), there is no output power.

When the current time is smaller than the timer stored time (step 709), the relay operation time has been reached, so the relay 6 is turned on (step 711) and the timer is operated on time. That is, the relay is driven or shut off by the time value comparison of the microprocessor 2.

In this way, the relay control in the on state or the relay control in the off state (FIGS. 5C, 5D, and 5E) results in smooth operation.

In addition, in the present invention, the display unit uses a dynamic display to minimize power consumption, and the operation of the relay is adjusted in units of 1 minute.

When performing the repeat mode, whenever the repetition period (RPT) starts the repetition using a pseudo-clock, this clock is set to form a period (RPT) and the time from the repetition period (RPT) Compared with that, the output power can be opened and closed. (Figure 5b, Figure 5c, Figure 5d, Figure 5e)

As described above, the timer of the present invention performing the operation as described above not only makes the control time of the controlled device (electrical product) accurate, but also repeatedly opens and closes the output power after a certain time (αH), so that the sunset of the heating apparatus used indoors It is possible to open and close repeatedly after the time and before sunrise, and it can also be used for home cooking utensils. It is superior to the existing electronic timer in terms of its function. If you select each mode by program key and operate it by setting the required timer time, The display unit displays the current time and is useful for opening and closing the controlled device through various control types such as on, off, repeat, on / repeat, off / repeat, on-off / repeat according to the set mode. An invention is a multifunctional electronic timer having a power switch function in addition to a general clock function.
