The present invention relates to a power-saving power strip that can be effectively applied to the characteristics of a power strip installed in a deep corner.

In general, the power strip used in a normal office environment or at home has a plurality of plug sockets, which can be used to supply power to various electronic devices by plugging in power plugs of various devices. It is provided with a power switch so that the power supplied to a plurality of power plug sockets can be supplied / blocked simultaneously or individually.

However, the conventional power strip of such a configuration must operate a separate power switch provided in the plug socket when operating the power of the peripheral electronic devices including the main electronic device while the plug of the electronic product is inserted into each plug socket as the power supply terminal. Power is cut off. Therefore, even if the main device is turned off, only the main device is in a power-off state, and the remaining peripheral devices are always in standby power mode, so that there is a problem in that power is not secured and unnecessary power is wasted.

Outputs each to make the respective devices in the multi-tap including the main control unit 100 in the standby operation state.

In this standby state, the main controller 100 receives the key inputs manipulated by the user through the switch input unit 31 or the remote control unit 32 of the function setting unit 30 by checking the overall operation of the power strip. Recognizes the various commands received from the user and sets the plug socket operation time zone of the user's desired tap in response to the command, or sets the user's password and the like, and then operates the desired relay through the multi-tap control unit 50. Power is supplied only to the socket, and whether or not the result of the command is performed is displayed on the LCD display unit 70, and the set data are stored in the memory unit 60, and the accident detection unit 13 When the operation of the relay on / off by controlling the output of the multi-tap control unit 50 according to the accident situation input from As such, it controls on / off of the power supply line supplied to the load.

On the other hand, in general, since the multi-tap is located in the corner because of its use characteristics, it is necessary to bend the body in the corner or remove the multi-tap to set the time and other functions. Therefore, in the present invention, since the remote control unit 32 takes most of the communication methods currently used, key input corresponding to the switch input unit 31 is possible, and thus it can be conveniently used. In this case, when the remote control unit 32 uses short-range RF communication that can be used for remote control as a wireless communication unit, first, by using near-field high-frequency (RF) communication, interference with an adjacent office is not generated. By using), the user can select the day of the week for which the user wants to use the power and the day that is not used, and select the use time of the selected date. In the high frequency receiver 33a, the memory unit for the above requirements of the user can be selected. The content is stored in (60) and used as a setting reference for the operation. You can also select the contents for the preset time.

In addition, the remote control unit 32 of the present invention by using the DTMF receiving unit 32a to receive the incoming signal through the external telephone line to transfer to the main control unit 100, this function is when the telephone ring signal is received through the external telephone line When the bell detection signal is input to the main control unit 100 and the main control unit 100 determines that the bell signal is a bell signal, the relay control signal is generated through the multi-tap control unit 50 to move the relay connected to the telephone line input terminal down. The connection is switched to determine the DTMF tone signal through the telephone line, and the main control unit 100 may send a response signal according to the input of the DTMF signal to the outside via the telephone line.

According to the present invention, it is equipped with a power saving function by various timers, and can be separated and controlled individually for a plurality of devices connected to the plug socket, thereby reducing the enormous power waste consumed in idle electric devices through timely and accurate power management for the electric devices.
