Referring to FIG. 1, the switching device 100 for a power saving device according to the present invention includes a power supply unit 110, a switching unit 140, an emergency switching unit 150, a CPU 120, and a signal input unit ( 130).

First, the power supply unit 110 receives commercial power (110 / 220V) and rectifies and outputs it, or outputs a constant voltage (device driving voltage) using a signal line of a used device, and the signal input unit 130 receives a signal input from the device. Is converted and output to the CPU 120, the CPU 120 is driven by a constant voltage applied from the power supply unit 110, and compares the input signal with the pre-stored data and outputs a switching signal if the signal is not in use. Here, when the signal input from the signal input unit 130 is the same as the stop state of use, the CPU 120 turns off the switching means 140 to block the commercial power from being applied to the device.

In addition, the switching means 140 is switched by a switching signal output from the CPU 120 to apply and cut off commercial power to the device. Here, the switching means 140 is composed of a photo triac 141 and a triac 142 as shown in FIG. 2. The photo triac 141 is turned on / off according to a switching signal output from the CPU 120, and is used to circuitally separate the commercial power supply 110 / 220V and the power supply 110, and the triac 142. ) Is used to interlock according to the on / off of the photo triac 141 to supply power to the device, and to protect the switching element even under an environment at high voltage. Meanwhile, the photo triac 141 and the triac 142 are used here, but other switching elements, that is, transistors, diodes, and relays, may be used.

Emergency switching means 150 is switched in accordance with an external operation is applied in parallel to the input terminal and the output terminal to the switching means 140 so that the device is operated by applying the commercial power (110 / 220V) to the use device. Here, the emergency switching means 150 is a dip switch or the like is used, it is preferably formed outside the apparatus main body (not shown).

Hereinafter, an operation of a switching device for a power saving device according to the present invention will be described in detail with reference to FIG. 1.

First, the user's switch operation for driving the device or an output signal from another device connected thereto is applied to the signal input unit 130, and the output of the signal input unit 130 is input to the CPU 120.

Then, the CPU 120 is driven through the power supplied from the power supply unit 110 to compare the signal applied from the signal input unit 130 with previously stored data. Thus, when the comparison result is a signal for the operation of the user device, that is, a signal generated for use by the user, the switching means 140 outputs a high signal to turn on the switching means 140. When the switching means 140 is turned on, the power of the device is applied to drive the user device.

In this state, the CPU 120 continuously checks the signal output from the device through the signal input unit 130. In this case, if the user generates a signal for stopping the use of the device, the CPU 120 turns off the switching signal. Then, as the switching signal is turned off, the switching means 140 is turned off and the power to the entire circuit is completely shut off. Therefore, the use of the device is stopped and power applied to the entire circuit of the device is cut off, thereby reducing the power in the entire circuit of the device. It is not consumed.

In addition, when the user device is added to another device to operate, when the flow of signals between the devices disappears or operates in the power saving mode, the CPU 120 detects this through the signal input unit 130 and turns off the switching signal. Then, the switching signal output from the CPU 120 goes low, and the switching means 140 is turned off, so that power to the entire circuit of the used device is completely cut off and there is no power consumed.

In addition, even after the power is completely shut off, the signal output from the use device is continuously checked through the signal input unit 130 to operate by applying detection power to the user's use signal or the operation signal of the device.

In addition, when the user manipulates the emergency switching means 150, commercial power (110 / 220V) is applied to the device.

When power is applied to the device, the device is operated. Thus, the device is used in the same manner as above, and when the use is completed, the power supply to the entire circuit of the device is cut off.

When the user presses the power switch 211 to use the computer 210, the signal is input to the input unit 130, the output of the signal input unit 130 is applied to the CPU 120 through which the CPU 120 of the user The switching means 140 is turned on by determining that the signal is a signal for use, so that the power of the computer 210 is supplied to use the computer 210. In this state, the CPU 120 continuously checks the signal of the power switch 211 of the computer 210 with the signal input unit 130. At this time, when the user presses the power switch 211 to suspend the use of the CPU 120 determines that the signal for use stops the switching unit to turn off the switching means 140, the power of the computer 210 is cut off. In addition, when a power-off signal is generated in the computer 210, the CPU 120 reads the signal from the signal input unit 130 and determines that the signal is a stop signal, thereby turning off the switching unit so that the switching unit 140 is turned off. Power off. As a result, the standby power consumes only the minimum power for driving the switching device for the power saving device, thereby minimizing the standby power.

From this signal line, the power supply unit 110 generates a voltage of a predetermined level, from which the CPU 120 operates. The signal input unit 130 receives this signal and outputs the signal to the CPU. The CPU 120 determines the signal output from the signal input unit 130 and turns on the switching unit when the signal is for a user's use so that the switching unit 140 is turned on to supply the power of the monitor 220 to monitor the monitor 220. Will be used. In this state, the CPU 120 continuously checks the signal of the monitor 220 signal line. At this time, if a signal for the power saving mode of the monitor 220 is applied from the computer 210, the CPU 120 determines the signal, and when the power saving mode signal is a signal, the switching unit 140 is turned off so that the monitor 220 is turned off. The power consumption in the power saving mode is zero because the power is turned off. On the contrary, when the power saving mode is canceled, the CPU 120 determines a signal and turns on the switching unit when the power saving mode is not in the power saving mode so that the switching unit 140 is turned on to use the monitor 220. In addition, when the use of the computer 210 is terminated, the signal from the display device is cut off from the main body of the computer 210, and the CPU 120 detects it through the signal input unit 130 to turn off the operation of the power supply unit 110. Then, the CPU 120 is turned off in response to the power supply 110 being turned off, the switching signal output from the CPU 120 is turned low, and the switching means 140 is turned off, so that power to the entire circuit is completely shut off and consumed. There is no power.

When the switching means 140 is turned on, a commercial power source 110 / 220V is applied, and the charger 230 charges the battery B. In this state, the CPU 120 continuously checks the charging signal through the signal input unit 130. At this time, if the battery B is fully charged, the operation of the power supply unit 110 is turned off. Then, the CPU 120 is turned off according to the power supply 110 off, the switching signal output from the CPU 120 becomes a low signal, the switching means 140 is turned off, and eventually the power to the entire circuit of the charger 230 Since the battery B is completely blocked, the charging of the battery B is stopped and power applied to the charger 230 circuit is cut off so that power is not consumed in the entire circuit of the charger 230.
