Description

Multi-tab concent for saving power consumption

The present invention relates to a multi-tap outlet, in particular, the power of the peripheral device that operates depending on the main body can be turned on or off according to the operation of the main body, that is, when the power of the main body of the peripheral device connected to the main body It is a power saving power strip outlet to turn on / off power supply together

The multi-tap outlet is an outlet having a plurality of outlets, and is a device for supplying operation power to a plurality of electronic devices. The power strip as disclosed in Korean Utility Model Publication No. 1996-38797 (published Dec. 18, 1996) has a main switch that can control the power supply to all outlets, and an auxiliary power control for each outlet. With switches, a power saving effect is achieved by selectively controlling the power supply to each outlet.

However, such a power outlet has a problem in that it is not possible to automatically control the power of peripheral devices such as a monitor or a printer according to whether the main body is used or not, for example, the on / off state of the computer. On the other hand, a recent computer has a power control function to perform a function of turning on / off its own power, but the power of a monitor, a printer, etc. connected to the computer cannot be turned on or off.

Accordingly, there is a problem that a user must separately operate a switch for peripheral devices. Therefore, the conventional multi-tap outlet is not only inconvenient for the user's work, but also causes unnecessary power consumption when the user fails to properly check the on / off state of the peripheral devices.

Recently, in such a power-saving power strip outlet, whether power is supplied to peripheral devices (monitors, printers, etc.) operating in dependence on the main body (computer, game machine, etc.) as in the relationship between a computer, a monitor, and a game console. Things that can be turned on and off are being implemented. The conventional power-saving power strip outlet has a separate outlet for the computer main body, and a power supply to an outlet for peripheral devices depending on whether a current is detected in a ct-type detector or a CT-type detector that detects the flow of current through the outlet. Relays for controlling the supply or not.

However, a power-saving power strip outlet having such a CT type current detector to control power supply to peripheral devices has a high cost because it has an expensive CT detector, and malfunctions according to the sensitivity of the CT detector and the amount of leakage current of the main body used. There is a problem that may cause.

The present invention is designed to solve the above problems, and an object thereof is to provide an improved power-saving power strip outlet that detects a signal applied to a communication port of a main body and controls a power supply to a peripheral device to achieve a power saving effect. .

A communication port connected to a communication port of the main body; And

And a relay switch for controlling a power supply to an outlet for a peripheral device according to the presence or absence of a signal applied to the communication port.

The power-saving power strip outlet according to the present invention does not have a built-in CT-type detector that is more expensive than a power-saving power strip outlet having a built-in CT type detector. It has the effect of stable operation almost irrelevant.

The power-saving power strip outlet according to the present invention may be configured in an integrated form of an outlet for a computer body and an outlet for a peripheral device, or on the other hand, may be implemented in a form having only an outlet for a peripheral device. In both forms, only the outlet for the peripheral is controlled by the presence or absence of a signal at the communication port.

The power-saving power strip outlet according to the present invention preferably further includes an auxiliary switch for enabling or disabling the control operation by the relay switch.

In addition, the power-saving power strip outlet according to the present invention is preferably further provided with a main switch to turn on / off the entire power supply and cut off the power when overloaded.

Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram schematically showing a form using a power saving power outlet. As shown in FIG. 1, the computer 112, the speaker 114, the DVD player 116, the monitor 118, the printer 120, the modem 122, and the scanner 124 using the power outlet 100 are illustrated. Power on. The power strip outlet 100 has a main switch 102, an outlet 104 for the body and an outlet 106 for peripheral devices, a plug 108.

The main switch 102 controls the power supply to the outlets 104 and 106, and automatically shuts off the power supply when overloaded. When the computer 112 connected through the outlet 104 for the main body is turned on, the multi-tap outlet 102 detects the operation of the main body and automatically controls the power supply to the outlets 106 for the peripheral devices.

2 is a block diagram showing a detailed configuration of a conventional power strip outlet, showing an example disclosed in Japanese Patent Application Laid-Open No. 2000-6660 (2000. 2. 7 Publication).

In FIG. 2, reference numeral NFB (No Fuse Braker) is a circuit breaker that is automatically cut off in order to prevent damage to the device in the event of overcurrent or overvoltage, and 202 is a first and second power switch respectively provided in the AC power line. (SW1, SW2) is the power switch unit for controlling the input power of the device by the on or off operation, 204 is to prevent the surge voltage (surge voltage) to be supplied to the rear end and to protect the data loss by the surge Surge protection.

In addition, reference numeral 206 is a power supply for rectifying the AC power through the surge protection unit 204 and make a plurality of DC voltages to supply to each end of the device, and reference numeral 208 is an AC power line supplied to the main body and peripherals of the computer. It is connected to one of the power supply line of the power supply control unit for detecting the presence or absence of leakage current, and generates a peripheral power supply control signal and the main body power control signal in accordance with the detected leakage current.

Reference numeral 210 is a peripheral power control unit that senses the leakage current and transmits it to the power control unit 208 and controls AC power supplied to the peripheral device in response to the peripheral power control signal generated by the power control unit 208.

In the conventional power strip configured as described above, when the first and second power switches SW1 and SW2 in the power switch unit 202 are turned on, input AC power is supplied to the system, and the supplied AC power is a surge protection unit 204. Each surge protection element (MOV1,-MOV5) in the circuit is removed after the surge voltage is supplied to the rear stage.

The power supply unit 206 provides a DC voltage by full-wave rectifying the AC power supplied to the rear end, and converts the DC voltage into a plurality of DC voltages required by the system and supplies the DC power to each end of the system (main body).

As described above, in a state in which driving power is supplied to each end of the system, the microcurrent sensing element CT in the peripheral power supply control unit 210 is connected to one power line of the AC power line supplied to the peripheral device to connect the main outlet CONT. The leakage current is sensed and the result is transmitted to the power control unit 208.

The power control unit 208 generates a peripheral power supply control signal and a main body power control signal in accordance with the presence or absence of a leakage current detected by the microcurrent sensing element CT.

3 is a circuit diagram showing a detailed configuration of the power control unit shown in FIG.

As illustrated in FIG. 3, the power control unit 208 amplifies the diode 302 for bridge rectifying the leakage current sensed by the peripheral device power control unit 210 and the DC voltage bridged at the diode 302 to a predetermined level. The amplifier 304, first and second resistors R6 and R7 for setting the reference voltage for changing the level of the externally supplied DC voltage to set the reference voltage Ref, the reference voltage and the amplifier set above ( Comparing the output voltage of the 304, and outputs the result of the comparator 306 and the output of the comparator 306 to control the current of the relay coil RY to generate the peripheral power supply control signal as a result SCR 308.

The power control unit 208 configured as described above bridges the leakage current sensed by the diode 302 and amplifies it by the amplifier 304 at a predetermined level. The comparator 306 compares the reference voltage set by the resistors R6 and R7 with the output voltage of the amplifier 304, and controls the SCR 308 based on the resultant to control the power supply and the main power supply of the peripheral device. Done.

The conventional multi-tap capacitor shown through FIGS. 2 to 3 must have a CT for detection of leakage current, and has a considerable cost burden due to the high price of the CT. Also, an amplifier for amplifying the leakage current detected through the CT, a comparator for comparing the output of the amplifier with a predetermined reference voltage Ref, and an SCR for controlling the relay coil RY according to the output result of the comparator. There is a problem that the cost burden is large because it must be provided.

In addition, there is a problem that the cost of the air for mounting these devices is consumed to increase the production cost, the production time takes a lot.

On the other hand, the conventional power saving type power outlet shown in FIG. 2 has a problem that a malfunction may occur due to a sensitivity characteristic of a CT for detecting a leakage current, a leakage current characteristic of a main body, and the like. In detail, when the CT is deteriorated and the sensitivity for detecting the leakage current is decreased, or when a main body having a small leakage current is used, the CT may not detect the leakage current and may not properly supply power to peripheral devices.

The power-saving power strip outlet according to the present invention is characterized in that the power supply of the peripheral device is controlled by detecting the power supply voltage applied to the communication port of the main body rather than detecting the leakage current of the main body. Since the multi-wall outlet according to the present invention does not detect leakage current, no expensive CT is required, and thus, cost cost is reduced because an amplifier, a comparator, and an SCR for processing the micro current detected by the CT are not required. This reduces production time.

On the other hand, when driving the relay coil with a power supply voltage applied to the communication port of the main body there is also an advantage that no separate DC power supply is required.

RS232C, UART, USB, and a parallel port for a printer may be used as the communication port of the computer. However, a USB port having a 5V power supply suitable for driving a relay is generally used.

Figure 4 is a schematic view showing an example of using a power strip outlet according to the present invention. The power strip 400 according to the present invention as shown in Figure 4 is a plug 402 for introducing commercial power, the main switch 404, a plurality of outlets 406 for peripheral devices, and a USB connection line ( 408.

The main switch 404 controls the supply of power to a plurality of outlets 406 for peripheral devices and has a function that automatically shuts off during overload and overcurrent. A control unit as shown in FIG. 5 is built in the power outlet 400, and the control unit may be connected to a plurality of outlets 406 for peripheral devices depending on the presence or absence of a USB power supply voltage connected through the USB connection line 408. Control the power supply.

5 is a block diagram showing a detailed configuration of a power saving power outlet according to the present invention shown in FIG. As shown in FIG. 5, a multi-wall outlet according to the present invention includes a plurality of outlets 406 connected in parallel to a rear end of a plug 402, a main switch 404, and a main switch 404 for introducing a power supply voltage. And a relay switch 408 interposed between the main switch 404 and the outlets 406 to open and close by a relay operation, and a USB connection line 408 for supplying driving power to the relay switch 410. Here, the plug 402 corresponds to the power input means in the summary of the present invention, and the plurality of outlets 406 corresponds to the first outlet in the summary of the present invention.

The relay switch 410 is driven by the USB power supply voltage (GND, + 5V) provided through the USB connection line 408 to control the power supply of the outlets 406 for peripheral devices.

On the other hand, the auxiliary switch 414 is for turning on and off the control function by the relay switch 410.

Operation of the apparatus shown in FIGS. 4 and 5 will be described in detail.

USB connection line 408 is connected to a USB port of the computer. When the computer is running, a USB power supply voltage is applied to the USB port. This USB power supply voltage is applied to the relay switch 410 via the USB connection line 408. The relay switch 410 is turned on by the USB power source applied through the USB connection line 408, so that a power supply voltage through the main switch 404 is applied to the outlets 404 for the peripheral devices.

When the computer is off, no power voltage is applied on the USB port, which in turn causes the relay switch 410 to be turned off, so that the power voltage through the main switch 404 causes the outlets 406 for peripheral devices. It will not be applied to.

That is, the power of the peripheral devices is automatically controlled according to the operation of the computer.

In the device shown in FIG. 4, a USB port 412 may be provided as shown in FIG. 6 instead of the USB connection line 408. In this case, a separate USB connection line 414 is connected to the USB port of the computer.

On the other hand, the multi-tap outlet of the present invention can be applied to a game machine having a communication port in addition to the computer.

When the auxiliary switch 414 is turned on, operating power is applied to the outlet 406 for peripheral devices regardless of whether the relay switch 410 is operated. This auxiliary switch 414 does not need to automatically control the power supply to the outlets 406 for peripheral devices in the power strip according to the present invention, i.e., when not used for peripheral devices belonging to the main body. useful. On the other hand, the auxiliary switch 414 may be a means for coping when the relay switch 410 is broken or inoperable for some reason.

The device shown in FIG. 7 is further characterized by an outlet 416 for the body. The main switch 404 controls the power supply to the computer body and peripherals. When the main switch 404 is turned on and the computer connected to the outlet 414 is operated, the relay switch 410 is driven by a USB operating power applied through the USB connection line 408 to allow the outlets 406 for peripheral devices. To control the power supply. Here, the outlet 416 corresponds to the second outlet in the summary of the present invention.

In the power strip outlet according to the present invention, it may be formed integrally with the plug. In this case, it can be used by inserting into an auxiliary outlet installed in a computer.
