That is, the microcomputer 31 outputs a signal for controlling the lock control unit 34. The plugs 3 to which the first power cord 2 is connected can be disconnected from the receptacle 16 by opening the covers 12 and 20 when the locking device is released.

Next, if the direct power control mode is selected in the main menu, the power control section 39 is controlled by the control panel 30 of the power control apparatus 10 so that power is supplied to the electronic apparatus 1, (1) can be used. At this time, the plug 18 to which the second power cord 17 of the power supply control apparatus 10 is connected should be connected to the outlet 4, a multi-tap, or the like. In the power direct control mode, the electronic apparatus 1 can be used by applying power in real time instead of time reservation. When the power supply direct control mode is turned OFF in the main menu, the control panel 30 of the power supply control apparatus 10 controls the power supply control unit 39 to turn off the power to the electronic apparatus 1, ) Can not be used. In addition, the power direct control mode can not use the electronic device 1 by turning off the power in real time instead of the time reservation.

Next, the first power supply reservation control mode is selected from the main menu to reserve the time zone. When the first power supply reservation control mode is selected, the screen of Fig. 11 is displayed. If you select to add or modify here, the screen of Fig. 12 is displayed.

The time setting can be entered in the separate keypad input window of the smartphone (5), and the input result can set the time (HH): minute (MM). Also, if you set it once today, you can set it by selecting the reservation only once in the repeat setting menu. In addition, when it is desired to repeat weekly, it is possible to select and set the corresponding day of the week, that is, Monday to Sunday, in addition to the weekly repeated reservation in the repeat setting menu. Accordingly, when the set power-ON start time comes, the control panel 30 controls the power control unit 39 to apply power to the electronic device 1. [ In addition, a notification sound or voice is output through the alarm unit 35 of the control panel 30 a predetermined time before the set power-on end time, for example, one minute before, so that the user can easily recognize. This is to induce the storage of documents in operation or the normal termination of the PC when the user uses an electronic device such as a PC. Then, the control panel 30 controls the power source control unit 39 to cut off the power applied to the electronic device 1 when the set power source end time is reached. On the screen of Fig. 12, a plurality of power ON start time and power ON end time can be selected and set, and can be modified by selecting to modify after the initial setting.

Also, when the list view / delete is selected on the screen of Fig. 11, the screen of Fig. 13 is displayed. In the screen of Fig. 13, one or more time zones set up to the present are displayed. If the corresponding delete button is pressed to erase the set time zone, the set time zone is deleted. Since the selection of the list is not displayed in the list any more, the control panel 30 is not controlled in the set time zone.

Next, when the second power supply reservation control mode is selected from the main menu of Fig. 10, submenus are displayed on the smartphone screen of Fig. Here, the cumulative total usage time for turning on the power, that is, the time (HH): minute (MM), can be set or the set time can be deleted.

Next, when the password setting mode is selected in the main menu of Fig. 10, a sub menu is displayed on the smartphone screen of Fig. Here, the user can set and store a password. The password can be a number, a letter, or a combination of more than six digits. It is preferable to input and input a plurality of passwords. When the password set by the smartphone 5 is normal, the password is transmitted to the control panel 30 and stored in the memory unit 36. The input of the password is for the security of the power supply control device 10 and is intended to allow the operation for power control only in the smartphone of the guardian so that the child or the third party can not operate the device unauthorized other than the guardian. Therefore, the guardian can set the password through the application for power control after the first connection with the smartphone and the power supply control device 10. Since all the power control apparatuses 10 are initially set with the same password, the user can arbitrarily change and set them.

Also, when communication is selected from the main menu of Fig. 10, a sub menu is displayed on the smartphone screen of Fig. In the submenu of the communication mode, one of Bluetooth, WiFi, and WiFi direct may be set as a communication protocol (mode). If you select one of the three and then select the Connect menu, the communication takes place. Although there are some differences in the communication procedure for each of the three modes, this part is done according to the communication protocol standard. For example, there is a paying process in the case of Bluetooth, and a connection process after scanning the wireless router (AP) in the case of Wi-Fi. Thereafter, the screen is switched to the screen shown in Fig. 17, in which a password set in this screen is input, and communication can be performed when the passwords match. The control panel 30 of the power supply control device 10 requests the smartphone 5 to input the password and confirms whether or not the password inputted from the smartphone 5 matches the password stored in the memory unit 36, The normal communication is performed between the smartphone 5 and the control panel 30 of the power supply control device 10 only when they match.

On the other hand, all of the electronic apparatuses incorporated in the microcomputer 31 of the control panel 30, particularly the electronic apparatuses to which the embedded system is applied, have a time error after a certain period of time. If these errors accumulate over a period of several years, errors may occur for several hours. Even if the microcomputer 31, which is precise and has excellent performance, this error occurs. However, a network-connected smartphone or PC can receive time from a time server that maintains standard time, which is commonly used worldwide, and time can be corrected. Therefore, the power control device 10 of the present invention needs to be accurate in time, and therefore it is necessary to correct the time error that occurs. Immediately after the communication between the smartphone and the power control device is performed, the time information received from the smartphone may be corrected based on the time information. During this time, the menu of the power control application installed on the smartphone becomes inactive and "Please wait a moment. This time is very short, so you will not feel uncomfortable. When the time correction of the microcomputer 31 of the control panel 30 is completed, a signal is sent to the smartphone 5, and the smartphone 5 activates the menu to use the menu.

Further, although the present invention has described Bluetooth communication, Wi-Fi communication, and Wi-Fi direct communication as the above-mentioned communication means, it is not limited thereto. Furthermore, it will include all existing communication methods (protocols) and all communication methods (protocols) to be applied to future smart phones. NFC, RFID, UWB, Zigbee, and mobile communication standards.

Although it has been described in the present invention that the time setting and the execution of commands are performed in an application for power control of a smartphone, this is not necessarily limited to a smartphone. In terms of hardware, it can be applied to various kinds of waved PCs including smart phones, smart pads, tablet PCs, smart watches, home robots, notebooks, and PCs. It is applicable to all products which can be run with OS (Operating System) as a software and can be loaded with separate application software for power control.
