Also, the voltage, current, and power information from the three-phase receptacle 100 can be received at certain time intervals at a specific event. For example, the outlet application execution at the terminal 200 may be a specific event.

The terminal timer 230 transmits a synchronization signal to the timer 180 of the three-phase receptacle 100 through the terminal communication unit 210 and operates according to the system clock of the terminal control unit 220. Here, the synchronization signal for synchronizing the timer 180 and the terminal timer 230 does not mean synchronization of the system clock but means synchronization of the timer.

The first switch block 210 and the second switch block 220 are connected to each other. The sensed voltages, currents, and power levels are transmitted to the terminal 200 through the communication unit 170 and the terminal communication unit 210 and transmitted through the display unit 240 to the first switch block 210 and the second switch block 220 ). The display unit 240 of the terminal 200 recognizes the voltage and current respectively applied to the two switches 130 and 132 by the control unit 160 of the three-phase receptacle 100 and transmits the voltage and current to the terminal 200 To the terminal control unit 220 through the terminal communication unit 200 of the terminal 100 at a predetermined time interval so that the terminal user can recognize the current state of the three-phase plug socket 100. The voltages and currents measured by the controller 160 are the voltages applied to the two switches 130 and 132 and the currents flowing through the switches 130 and 132 but the respective sockets 140 and 142 themselves serve as loads It can be determined that the voltages and currents applied to the respective switches 130 and 132 and the sockets 140 and 142 are substantially equal to each other.

Meanwhile, the power is a value obtained by multiplying the current voltage level by the current amount, and the amount of power is also divided into the first switch block 210 and the second switch block 220 through the display unit 240.

4 to 6, the outlet application is displayed by an input of an on-switch key for turning on the switch, an off-switch key for turning off the switch, a timer key for setting an operation time of the timer, A number for inputting the set time and a numeric key for indicating an input key for determining the input of the set time are separately displayed for each socket 140 and 142. [ For example, when the user clicks the OFF switch with respect to the second switch 142, the second switch 132 of the three-phase receptacle 100 is immediately turned OFF.

On the other hand, a step of controlling any one of the two switches will be described. For example, it is assumed that the first switch 130 is controlled. Since the control of the second switch 132 is also the same, description thereof will be omitted.

In step S202, the three-phase receptacle 100 waits for a control command from the terminal 200. [ Generally, since the three-phase receptacle 100 is often used for industrial applications such as a construction site and a factory site, the terminal 200 is connected to a wide area communication 2G to 5G communication, a LTE communication or a wide area WiFi .

In step S204, the communication unit 170 of the three-phase receptacle 100 receives a control command from the terminal 200 user. The control command can be input through the outlet application according to the above-described Figs. 4 to 6.

If the control input is inputted through the outlet application executed in the terminal 200 in step S206, it is determined whether or not the timer is set. At this time, an on / off control command is inputted together through the user terminal. In other words, whether the on / off control is to be performed after the timer is clicked is also input. After the timer and the on / off control command are inputted, the number keys as shown in Fig. 6 are displayed.

In step S208, the three-phase receptacle 100 receives the set time from the terminal 200 when the control command input by the user in the determination step is the timer setting (step S206, Y).

In step S210, the three-phase receptacle 100 elapses the set time input by the user through the terminal 200. [

In step S212, the user turns on or off the first switch 130 according to the on / off command inputted together with the set time inputted through the terminal timer 180. [ On the other hand, the step of turning on or off the first switch 130 will be described in detail with reference to FIG. 8 to be described later.

On the other hand, if the control command input by the user in the determination step is not the timer setting (step S206, N), the three-phase receptacle 100 proceeds to step S212 described above.

FIG. 8 is a flowchart illustrating a process of turning on or off according to FIG. 6 of the present invention in more detail.

Referring to FIG. 8, in step S302, the control unit 160 determines whether the control command input through the terminal 200 is an on-switch key input or an off-switch key input in step S302.

In step S304, it is determined whether the first switch 130 is in an ON state when it is determined that a switch key has been input through the terminal 200 (step S302, on switch input).

If the first switch 130 is not turned on, the first switch 130 is turned on (step S306). If the first switch 130 is in the ON state (step S304, N), the ON state is maintained since the current ON state of the first switch 130 is ON (the ON switch key input in step S302) And ends.

In step S308, it is determined whether the first switch 130 is in the ON state when it is determined that the OFF switch key is inputted through the terminal 200 (step S302, inputting the OFF switch key).

If the first switch 130 is on, the first switch 130 is turned off (S308, Y) (S310). If the first switch 130 is in the off state (step S308, N), the current switch 130 is in the off state and the off command is input (off switch key input in step S302) do.
