The computer main body power control device according to the operating state according to the present invention includes a computer main board 100 and a power supply device 200.

The computer main board 100 serves to operate the computer in a plurality of operating modes. Here, the plurality of operation modes include at least one or more of a commercial power cut-off state, an off mode, a maximum power saving mode, a standby mode, and a basic operation mode.

It cuts off the standby power to maintain its versatility.

The power supply 200 measures the power consumption according to the operating mode, actively automatically generates and stores a reference value for shutting off standby power for each operating mode, and measures the power consumption reference value according to the measured operating state in real time. The power consumption of the computer main board 100 is compared, and the power switch 220 is controlled according to the comparison result to control the power of the computer main board 100, and the state of the computer main board 100 is changed.

By providing, it is preferable to realize power saving by cutting off standby power.

Here, the power control unit 230 may be implemented as firmware and mounted on a control device of an existing power supply device to implement power saving through power control of the computer main board 100 without adding hardware.

In addition, the power supply device 200 includes a power generator 210 that generates power to supply the computer main board 100, and a power switch 220 that supplies or cuts power to the computer main board 100. ).

In addition, the power control unit 230 is a power consumption measurement unit 231 for measuring the operating state of the computer main board 100 and power consumption according to a device mounted on the computer in connection with the power generation unit 210, A power supply device status check unit 233 that detects the state of the power supply device 200, a computer power button recognition unit 232 that detects a power button recognition signal by detecting a change in the power line impedance of the computer main board 100 ), a mainboard status check unit that stores power consumption according to the operating state of the computer in connection with the power consumption measurement unit 231, and checks the state change of the computer mainboard 100 using the measured power consumption (234), the power consumption measured by the power consumption measurement unit 231 is automatically generated and stored as a reference value for each operating state for blocking standby power, and a power consumption reference value according to the measured operating state and real-time The power consumption of the computer main board measured by is compared, and the power switch 220 is controlled according to the comparison result to control the power of the computer main board 100, and the main board status check unit 234 Based on the check result, when the computer main board 100 is changed, the state of the power supply 200 is initialized, and a reference value is determined according to each operating state based on the changed power consumption measurement value of the computer main board 100. It includes a control unit 235 that automatically regenerates and controls the power of the changed computer main board.

Preferably, the power control unit 230 detects the amount of change in impedance of the power button switch line 10, recognizes it as a power button recognition signal, and determines that the power button has been operated when an impedance change amount is detected as a result of the recognition. Control so that power is supplied to the computer main board 100.

The operation of the computer main body power control device according to the operating state according to the present invention configured as described above will be described in detail as follows.

First, when commercial AC power (AC power) is input to the computer, the power generation unit 210 of the power supply device 200 generates and supplies standby power for supply to the computer main board 100. At this time, the power switch 220 is turned on from the initial state and supplies standby power generated by the power generation unit 210 to the computer main board 100. Thereby, the computer main board 100 operates in a standby state.

When standby power is supplied to the computer main board 100, the power consumption in the power control unit 230 is measured and the standby power supplied from the control unit 231 to the computer main board 100 is measured as the power consumption of the computer, and is turned off. It is stored in the internal memory as a reference value for blocking standby power at the time. Here, the power consumption varies depending on the operating settings of the computer and various devices installed in the computer.

In the standby state, when the user presses the power button switch provided in the main body to use the computer, the computer power button recognition unit 232 of the power control unit 230 detects the amount of change in the impedance of the power button switch line 10 The power button recognition signal is transmitted to the control unit 235.

Here, the impedance of the power button switch line 10 connected between the power supply 200 and the computer main board 100 is detected when the power button switch is turned on while the power button switch is off, and this impedance is sensed. Recognized as a power button recognition signal.

In addition, when the power button recognition signal is transmitted, the control unit 235 recognizes that the user has operated the power button switch, maintains the switching state of the power switch 220, and controls the power generation unit 210 to Control to generate power.

In response to this control, the power generation unit 210 full-wave rectifies and smoothes the input commercial AC power to generate a DC power corresponding to a predetermined main power and supplies the main power to the computer main board 100.

As a result, the computer is in a normal operating and operating state, and even in this case, the control unit 235 measures the power consumed by the computer main board 100 as the power consumption through the power consumption measurement unit 231 in real time. In this case, the measured power consumption is the power consumption corresponding to the basic operating mode of the computer and is stored in the internal memory.

Meanwhile, the computer main board 100 operates in five power modes according to the operating state of the computer. That is, the commercial AC power off state, off mode, hibernation mode, standby mode and basic operation mode.

Here, when the computer main board 100 operates in five modes, power consumption varies according to each operating mode and various installed devices.

For example, when the user does not use the computer for a long period of time in the computer, the computer mainboard 100 switches the operating state to the standby mode, and in the standby mode, depending on the user's settings, the hibernation mode or the user switches the power button. When turned off, the computer switches to the off mode, and power consumption varies depending on the operating state.

The power consumption, which varies depending on the operating state of the computer, is measured in real time by the control unit 235, and it is checked whether the main power is off through the power supply status checker 233. If the main power is not in the off state, the computer It recognizes as on and repeats the process of measuring the power consumption of the computer in real time. On the contrary, if the main power is turned off during the process of measuring power consumption in real time, the power consumption measured in real time according to the operating state of the computer is compared with the reference power consumption measured in the initial standby mode and stored in the off mode. do.

As a result of the power consumption comparison, when the currently measured power consumption is higher than the reference power consumption in the off mode, it is determined that the current operating state of the computer is in the standby mode, and the current state is maintained.

Contrary to this, when the currently measured power consumption is lower than the reference power consumption in the off mode or equal to the power consumption in the off mode, it is determined that the operating state of the computer is the off mode or the maximum power saving mode, and the power supply By controlling the switch 220, the power switch 220 is turned off. When the power switch 220 is turned off, power generated by the power generating unit 210 is not supplied to the computer main board 100. As a result, the computer main board 100 does not consume power at all, and thus the best power saving is implemented.

For example, the present invention distinguishes the state of power consumption consumed in operating a computer, actively automatically generates a reference value for shutting off standby power, and detects the power consumption for each operating state in real time to achieve a specific state. When (off mode or hibernation mode), that is, when standby power is not required from the computer main board, the standby power supplied to the computer main board is completely cut off to realize ultra power saving.

When the power of the computer main board 100 is turned off, when the user presses the power button switch to use the computer, the impedance of the power button switch line 10 is detected, and the power control unit 230 recognizes the computer power button. The unit 232 detects this, generates a power button recognition signal, and transmits it to the control unit 235.

When the power button recognition signal is transmitted, the control unit 235 recognizes that the power button switch has been operated, and immediately turns on the power switch 220 so that the power generated by the power generation unit 210 is transferred to the computer main board 100. Be supplied.

On the other hand, as another feature of the present invention, even when the computer main board 100 in use is changed (replaced), computer power saving is continuously implemented, thereby improving versatility.

For example, the power consumption measurement unit 231 of the power control unit 230 measures power consumption according to an operating state of the computer main board 100 and a device mounted on the computer in connection with the power generation unit 210 .

Subsequently, the main board status check unit 234 stores the respective power consumption according to the operating state of the computer in connection with the power consumption measurement unit 231, and uses the measured power consumption to determine the state of the computer main board 100. Confirm the change. Here, the power consumption of each computer main board may be different. Therefore, the power consumption measured every time the computer boots is accumulated and stored, averaged, and then, based on the average value, it is checked whether the computer main board is changed. As a result of this check, when it is confirmed that the change (eg, replacement) of the computer main board 100 is replaced, the main board change information is transmitted to the control unit 235.

The control unit 235 implements power saving by controlling standby power or main power control of the computer main board 100 in the same manner as before in a state in which the main board change signal is not received, and the main board status check unit ( When the main board change information is received from 234, the state value of the power supply 200 is initialized. Next, based on the changed power consumption measurement value of the computer main board 100, a reference value is automatically regenerated according to each operating state to control the power of the changed computer main board.

Power control, as before, detects the power consumption that varies depending on the operating mode of the computer main board 100 and the installed device in real time, and when standby power is unnecessary, standby power supplied to the changed computer main board 100 Power consumption is prevented by blocking power consumption, and thus, even when the computer main board is replaced, it is possible to control the standby power supplied to the changed computer main board without additional work, thereby maintaining versatility.

2 is a flow chart showing a method for controlling power of a computer main body according to an operating state according to the present invention, where S represents a step.

As shown in FIG. 2, the method for controlling the power of the main body of the computer according to the operating state according to the present invention comprises the steps of (a) measuring power consumption when commercial power is supplied and booting the computer and storing it as an off-level reference value ( Steps S101 to S103), (b) comparing the stored off-level reference value with the previously accumulated and stored off-level reference value to check the state of the main board (S104), (c) the verification result of step (b) When the main board is changed, the state value of the previous main board is initialized, and the saved off-level reference value is registered as the off-level reference value of the new computer mainboard, so that power consumption can be continuously controlled even when the mainboard status is changed. Steps (S105 to S106), (d) turning on the computer when the power button switch provided in the computer body is turned on, and measuring power consumption according to the operation of the computer in real time (S107 to S109), (e) the computer Checks whether the main power is off, and if the main power is not off, it is determined that the computer is running in the on state, and moves to step (d), and if the main power is off, Determining that the computer is running in the standby mode or the off mode (S110), (f) in the case of the standby mode as a result of the step (e), the off-level reference value stored in the step (a) and the step (d) Checking the operating state of the computer by comparing the power consumption measured by the computer operation (S111), (g) the power consumption of the computer is lower than the off-level reference value as a result of the confirmation in step (f) When the operating state of the computer is in the off mode, the step of cutting off standby power supplied to the main board of the computer (S112), (h) in the state in which the standby power supplied to the computer main board is cut off, the power button switch is turned on. Checking whether the operation is in a state (S113), (i) If the power button switch is operated in the ON state as a result of the confirmation in step (h), standby power is supplied to the computer main board, and a power button event If the occurs, including processing the event operation (S114 to S116). In step (i), the amount of change in impedance of the power line is sensed and recognized as a power button recognition signal.

The operation of the method for controlling power of the main body of the computer according to the operating state according to the present invention configured as described above will be described in detail as follows.

First, when commercial AC power (AC power) is input to the computer in step S101, the power generation unit 210 of the power supply device 200 generates and supplies standby power for supply to the computer main board 100. At this time, the power switch 220 is turned on from the initial state and supplies standby power generated by the power generation unit 210 to the computer main board 100. Thereby, the computer main board 100 operates in a standby state.

When standby power is supplied to the computer main board 100, the power consumption measurement and the control unit 231 in the power control unit 230 in step S102 measure the standby power supplied to the computer main board 100 as the power consumption of the computer. , In step S103, the power consumption when turned off is stored in the internal memory. That is, during initial booting, power consumption that varies depending on the device installed in the standby mode is actively automatically generated and stored as a reference value for blocking standby power.

In the standby state as described above, in step S104, the mainboard status check unit 234 compares the stored off-level reference value with the previously accumulated and stored off-level reference value to check the status of the mainboard. Here, the state of the main board means a state to check whether the main board has been replaced and changed to a new main board. Subsequently, if the currently stored off-level reference value and the averaged off-level reference value differ by exceeding a predetermined error range, it is determined that the main board has been changed. Subsequently, the main board change information is transmitted to the control unit 235.

As a result of checking the state of the main board in step S105, the controller 235 moves to step S106 when the main board is changed, initializes the state value of the previous main board, and uses the stored off-level reference value of the new computer main board. It is registered as an off-level reference value so that power consumption is continuously controlled even when the state of the main board is changed.

Next, when the user presses the power button switch provided in the main body to use the computer as in step S107, the impedance change amount of the power button switch line 10 in the computer power button recognition unit 232 of the power control unit 230 Is sensed and transmitted to the control unit 235 as a power button recognition signal.

Here, the impedance of the power button switch line 10 connected between the power supply device 200 and the computer main board 100 is detected when the power button switch is turned on while the power button switch is turned off. When the power button recognition signal is transmitted, the control unit 235 recognizes that the user has operated the power button switch, and while maintaining the switching state of the power switch 220, the control unit 235 controls the power generation unit 210 to control the main power supply. Control to create

In response to this control, the power generation unit 210 full-wave rectifies and smoothes the input commercial AC power to generate a DC power corresponding to a predetermined main power and supplies the main power to the computer main board 100.

As a result, the computer is in a normal operating and operating state in step S108. Even in this case, as in step S109, the controller 235 measures the power consumed by the computer main board 100 as power consumption. In this case, the measured power consumption is the power consumption corresponding to the basic operating mode of the computer and is stored in the internal memory.

Meanwhile, the computer main board 100 operates in five power modes according to the operating state of the computer. That is, the commercial AC power off state, off mode, hibernation mode, standby mode and basic operation mode.

Here, when the computer main board 100 operates in five modes, power consumption varies according to each operating mode.

For example, when the user does not use the computer for a long period of time in the computer, the computer mainboard 100 switches the operating state to the standby mode, and in the standby mode, depending on the user's settings, the hibernation mode or the user switches the power button. When turned off, the computer switches to the off mode, and the power consumption varies according to the operating state.

The power consumption, which varies depending on the operating state of the computer, is measured in real time by the control unit 235, and in step S110, it is checked whether the main power is off through the power supply status checker 233, and the main power is turned off. Otherwise, it recognizes that the computer is on, and repeats the process of measuring the power consumption of the computer in real time.

On the contrary, if the main power is turned off during the process of measuring power consumption in real time, it moves to step S111, and the power consumption measured in real time according to the operating state of the computer and the power consumption measured and stored in the initial standby mode are stored in the off mode. Compare the power consumption.

As a result of the comparison of the power consumption, when the currently measured power consumption is higher than the power consumption in the off mode, it is determined that the current operating state of the computer is in the standby mode, and the current state is maintained.

Contrary to this, if the currently measured power consumption is lower than the power consumption in the off mode or equal to the power consumption in the off mode, it is determined that the operating state of the computer is the off mode or the maximum power saving mode, and step S112 Moving and controlling the power switch 220, the power switch 220 is turned off. When the power switch 220 is turned off, power generated by the power generating unit 210 is not supplied to the computer main board 100. As a result, the computer main board 100 does not consume power at all, and thus the best power saving is implemented.

For example, the present invention distinguishes the state of power consumption consumed in operating a computer, detects differential power consumption for each operating state in real time, and enters a specific state (off mode or hibernation mode), that is, When standby power is no longer needed on the computer main board, the standby power supplied to the computer main board is completely cut off to realize ultra power saving.

When the power of the computer main board 100 is turned off, when the user presses the power button switch to use the computer as in step S113, the impedance of the power button switch line 10 is sensed, and the power control unit 230 The computer power button recognition unit 232 detects this, generates a power button recognition signal, and transmits it to the control unit 235.

In step S114, when the power button recognition signal is transmitted, the control unit 235 recognizes that the power button switch has been operated, and immediately turns on the power switch 220, so that the power generated by the power generation unit 210 is transferred to the computer main board ( 100).

In addition, in step S115, it is checked whether a power button event occurs, and if the power button event occurs, the process moves to step S116 to perform a reserved special event operation.

The present invention measures the power consumption of the computer from the time when the commercial AC power is applied to the computer, and identifies and identifies the power consumption for each mode by operating state without additional set data while being active. Controls the power of the computer main board by checking the status of the computer and controlling the power supply.

As a result, the power consumed in operating the computer is classified by operating state and supplied to the computer main board when the computer enters a specific state (off mode, hibernation mode), that is, when standby power is no longer needed. The standby power is completely cut off to realize ultra power saving.

In addition, even when the computer main board is changed due to replacement, etc., without the inconvenience of adding and operating a separate device, the off-level reference value of the new main board is actively automatically generated and stored, and real-time power consumption is detected by feeling. In this way, the standby power or main power of the computer main body can be controlled, so that versatility can be improved.

Although the invention made by the present inventor has been described in detail according to the above embodiment, the invention is not limited to the above embodiment, and can be changed in various ways without departing from the gist of the invention.
