As illustrated in FIG. 3, the liquid crystal display unit 300 is configured at the time of setting a timer and a digital type information display unit 310 which is displayed as a digital type so as to grasp the current time and a function set according to the purpose. One time consists of an analog type information display unit 320 in which the analog type is displayed.

The operation of the present invention configured as described above will be described in detail with reference to FIG.

When the power control key 210 is operated to operate the multipurpose timer of the present invention, the AC power applied from the external commercial power source is converted into a stabilized DC power through the power supply unit 600 and supplied into the circuit according to the opening of the switch.

The microprocessor 110 of the central processing unit 100 detects a power-on signal according to a control program pre-stored in the memory 120, and initializes all internal memory areas of the microprocessor 110 to '0'. The input / output terminal 110 is set as an input or an output so that a control signal is input or output.

In addition, the microprocessor 110 inputs a constant value to the timer to generate a reference time of the system, and initializes the internal timer to regularly generate an interrupt by the internal timer every 1/1000 seconds, and displays the current time. By inputting a value of "1:00" into the operation memory, the current time is "1:00" at the same time as the operation of the power supply control key 210, and the digital display unit 310 of the liquid crystal display unit 300 is a digital type. When the timer is set, the analog display unit 320 displays a character of '1' to '24' indicating the circular dot display and the time so that the user can easily grasp the remaining time and the elapsed time.

In more detail with respect to the initialization state, with the operation of the power control key 210, the microprocessor 110 detects a power application signal and operates according to a pre-programmed initialization operation program.

In the initialization operation program, the memory 120 is stored in the initialization state by inputting and storing a value of '0' in the memory 120 inside the microprocessor 110 and for displaying the output characters of the liquid crystal display device 300. In this case, the initialization screen is output to the liquid crystal display device 300 by inputting the digital type current time and the analog type dot and function display information to the storage space allocated to the memory 120.

In addition, the microprocessor 110 sets the properties of the input and output terminals so that the peripheral device and the control signal can be interchanged with each other. The function key connected to the power state monitoring circuit of the input device unit 200 is set as an input terminal. In order to set a terminal, a value of '0' is input to a storage space allocated to the memory 120, and the light emitting device unit 400, the alarm sound generating unit 500, and the relay connected to the liquid crystal display unit 300 are connected. A terminal connected to an element such as 800 completes input / output terminal setting by inputting a value of '1' into a terminal setting storage space of the memory 120 to set as an output terminal.

In addition, an internal real time clock every 1/1000 second using an 8-bit real time clock mounted in the microprocessor 110 to generate a reference time in the operation of the microprocessor 110. In order to generate interrupts periodically, input a constant value to the internal real time clock every cycle to use the interrupt cycle as a reference time, and generate 1 second by integrating 1/1000 second 1000 times and 1 second 60 times. It is configured to generate 1 minute by integrating so that the current time is displayed based on seconds and minutes, and the colon (:), which is a standard for dividing hours and minutes, blinks every second.

As described above, after the initialization operation of the device is completed, the microprocessor 110 operates according to a main program pre-programmed in the memory 120 to perform a function.

The main program compares a program for processing an input command according to an operation of a function key of the input device unit 200 with the current time to a timer operating time setting value represented by an analog type to operate or cut off the relay 800. Is divided into programs.

A program for processing a command input according to a function key operation of the input device unit 200 receives a signal of a function key of the input device unit 200 and performs a corresponding operation.

When the lamp control key 220 is pressed, the lamp of the light emitting device unit 400 is turned on by a flip-flop operation of an internal circuit, and the letter 'LAMP' is displayed on the liquid crystal display unit 300 and then pressed again. By the flip-flop operation of the internal circuit, the lamp goes out and the letter 'LAMP' disappears.

When the alarm control key 240 is pressed, the alarm is set by the flip-flop operation of the internal circuit, and the letter 'ALARM' is displayed to indicate that the alarm function is set on the liquid crystal display 300.

When the alarm control key 240 is pressed again, the alarm setting is released by the flip-flop operation of the internal circuit and the letter 'ALARM' disappears.

When the alarm function is set, the alarm sound is generated from the alarm sound generator 500 inside the circuit when the current time displayed in the digital type reaches a timer set value compared to a timer set value preset by the user. 800 is operated to supply or stop the power to the power control target equipment.

If the user presses the alarm control key 240 again to stop the operation after confirming the alarm sound generation, the alarm sound generation is stopped.

When the user operates the mode setting key 230 to set a function according to the purpose, the LCD panel unit 300 operates in the operation mode, clock mode, and timer mode according to the signal. The mode is switched in order, and the user selects and uses the desired mode.

The time adjustment mode will be described with reference to FIG. 5 which is an explanatory flowchart of the time adjustment mode.
