Description

A kind of power plugboard device and control method thereof

Technical field

The present invention relates to energy-saving electric power plate technical field, relate to a kind of energy-saving electric power board plug device and control method thereof of computer concretely.

Background technology

At present; The energy-saving electric power plate that is successfully applied to computer all is the input current value size through the host power supply of sampling detection computations machine; Compare with the input current value of host power supply under the various operating states of the main frame that prestores; Differentiate the host work state of current computer, the power connection and the cut-out of respective socket on the control electric socket; And the input current value of host power supply under the various operating states of the main frame that prestores is the input current value of the host power supply under the various operating states of main frame, preserved through the method sampling of study in advance; So when the host hardware of computer is changed; The input current value that must preserve host power supply under the various operating states of main frame through the method sampling of study again; That is to say: along with the host hardware of computer is aging; Must often to sample again and preserve the input current value of the host power supply under the various operating states of main frame through the method for study, otherwise, the power connection and the cut-out of respective socket on the electric socket can not correctly be controlled; In a word, because the input current value of the host power supply that will under the various operating states of main frame, preserve through the method sampling of study in advance, thereby cause the energy-saving electric power plate directly not exchange; Along with the host hardware of computer is aging, also must learn again, otherwise control unreliable; Pretty troublesome, inconvenience.

Known from institute, the current computer system considers from energy-conservation, safe angle when not needing long-range calling out, and is directly to cut off the electricity supply through mains switch on the electric socket or the total lock of powered-down, and often operation is very inconvenient.

Current computer all has ACPI (abbreviation of Advanced Configuration and Power Interface) " ACPI ", and ACPI has six kinds of states, be respectively S0 to S5, their the representative implication be respectively:

S0: abbreviate complete intact the unlatching as, i.e. the normal operating conditions of computer, all hardware equipment all is in to be opened or the state of operate as normal; In fact our usual operating state that Here it is; All devices standard-sized sheet, power consumption generally can surpass 80W, and this moment, the main frame power supply was in opening;

S1: abbreviate POS (Power on Suspend, CPU quits work) as, other hardware device is operate as normal still; Exactly except CPU being closed through the cpu clock controller; Other parts are operate as normal still, and power consumption at this moment is below 30W (some CPU cooling software utilizes this operation principle exactly in fact) generally, its wakeup time: 0 second; Usually be called POS standby or S1 standby, this moment, the main frame power supply was in opening;

S2: CPU is closed, but remaining hardware device still turning round, is exactly that CPU is in the state of decommissioning; Bus clock also is closed; But remaining equipment still turns round, its wakeup time: 0.1 second, this moment, the main frame power supply was in opening; Yet present this pattern is not used usually;

S3: abbreviate STR (Suspend to RAM suspends to internal memory) as, with closing hard disk behind the operating data write memory; Be exactly the STR (Suspend to RAM) that we are familiar with; At this moment power consumption is no more than 10W, its wakeup time: 0.5 second, be called STR standby or S3 standby usually; At this moment main frame power-off (soft-off) relies on the 5VSB of host power supply to provide electric current to supply internal memory RAM;

S4: abbreviate STD (Suspend to Disk as; Suspend to hard disk); Memory information writes hard disk, and all parts quit work then, at this moment main frame power-off (soft-off); Its wakeup time less than: 30 seconds, our usually said computer dormancy just (STD park mode or claim hibernate mode);

S5: be called for short shutdown, all hardware equipment (comprising power supply) is closed all, i.e. powered-down (soft-off), just computer shutdown (shutdown).

S1 to S4 state is to be used for the energy-conservation and quick complete intact computer system of opening of computer system, and the S2 pattern does not adopt usually at present, and commonly used is S1, S3, S4 pattern, just: POS standby, STR standby, STD dormancy; The S0 state is exactly the computer booting (complete intact the unlatching) that we often say; S5 is exactly the computer shutdown (soft-off) that we often say.

The main frame power supply is in unlatching with respect to S0 state to S2 state; The main frame power supply is in shutdown (soft-off) with respect to S3 state to S5 state; Be that the main frame power supply only exists accessory power supply work, output standby voltage+5VSB (+5V Standby).

Waking up all of S1 state to S4 state can power knob wakes up on the plate through pressing in face of the mainframe box, gets back to the S0 state; S1 state, S3 state be the tool function that quilt is not waken up from the state of deenergization not, and the general computer of S4 state is not supported from the state of deenergization, to be waken up.

In order to observe the current computer system running state; On the mainboard of computer, have ACPI led state lamp, know that state that computer system operates in S0 state, S1 state, S3 state, S4 state and S5 state through observing corresponding ACPI led state lamp; The positive pole of ACPI led state lamp all is to be connected with the power supply of computer; The negative pole of ACPI led state lamp is connected with corresponding output pin on the computer motherboard; So when output pin is low level; Corresponding ACPI led state lamp is lighted, and when output pin was high level, corresponding ACPI led state lamp extinguished.

ACPI led state lamp often has three kinds of manifestation modes to S1 state, S3 state now:

A kind of is to be connected to cabinet on the utilization computer motherboard to represent that current computer system be in S1 state or S3 state when the power supply indicator Power Led of plate glimmers in front; And the normal bright expression current computer of power supply indicator system is in the S0 state, and power supply indicator extinguishes expression current computer system and is in S4 state or S5 state;

A kind of is to increase a Sleep Led status indicator lamp to represent S1 state and S3 state, when the current computer system is in S1 state or S3 state, and Sleep Led status indicator lamp Chang Liang; When the current computer system was in S0 state, S4/S5 state, Sleep Led status indicator lamp extinguished;

Also having a kind of is on computer motherboard, to build the corresponding S1 state of S1 status lamp, the corresponding S3 state of S3 status lamp in separately; Like the GA-EP45-DS4 of Jijia mainboard; In build four ACPI led state lamps, respectively corresponding S0, S1, S3, S4/S5 state, computer is in that state; Corresponding status lamp Chang Liang, all the other status lamps extinguish; That is to say with respect to S1 status lamp, S3 status lamp: when the current computer system was in the S1 state, S1 status lamp Chang Liang, S3 status lamp extinguished, and when the current computer system was in the S3 state, S3 status lamp Chang Liang, S1 status lamp extinguished; When the current computer system was in S0 state, S4/S5 state, S1 status lamp, S3 status lamp all were in and extinguish.

Consider that from the angle of information preservation, system safety when cutting off the main frame power supply, computer system should be located S4 state or S5 state, preferably under the S5 state, cut off the main frame power supply certainly; So when computer system is in the S0 state, before the cut-out main frame power supply, should close (soft-off) computer systems division earlier, under the S5 state, cut off the main frame power supply; When computer system is in S1 state or S3 state, cut off the main frame power supply before, should carry out system wake-up earlier after, close (soft-off) computer systems division again, cut-out main frame power supply under the S5 state.

To S1 state, S3 state, very clear know that the current computer system is in S0 state or S3 state from ACPI led state lamp.

Know from the corresponding main frame mains switch of computer system state characteristic: when computer system was in S0 state or S1 state, the main frame power supply was in unlatching; When computer system was in S3 state, S4 state, S5 state, the main frame power supply is in closed (soft-off).

Know from above analysis: as long as obtain the status lamp information of S1 state and S3 state; And the information of correctly representing host power supply to open and close on the mainboard, just can differentiate S0 state, S1 state and S3 state, S4 state and the S5 state that is in S0 state to S5 state when computer system; When the host power supply unlatching, S1 status lamp, S3 status lamp all do not have the S1 state, the S3 state information shows, explain that working as computer system is in S0 state, i.e. complete opening; Show when S1 status lamp or S3 status lamp have S1 state, S3 state information, explain that working as computer system is in S1 state or S3 state, i.e. POS standby or STR standby; Close when host power supply is in (soft-off), S1 status lamp, S3 status lamp all do not have the S1 state, the S3 state information shows, explain that working as computer system is in S4 state or S5 state.

Known from institute; The ATX of main frame (BTX) power supply; When in a single day the power supply ac input end had the alternating current of 220V, the accessory power supply that comprises was just started working, output standby voltage+5VSB (+5V Standby); + 5VSB refers to that the one+5V that closes ATX (BTX) the power supply reservation of (soft-off) back in computer system waits for voltage; Be used for waking up of system, be called the standby power voltage of computer ATX (BTX) power supply usually, it supplies with the inner part of computer motherboard will keep working chip under off-mode; + 5VSB circuit is an independent power circuit in the inside of ATX (BTX) power supply, and no matter whether computer booting to be, as long as plug in plug, and the power supply energising ,+5VSB just exists.When the ATX of main frame (BTX) electric power starting, the output of ATX (BTX) power supply supplies the power supply of computer motherboard to have: 5V, 12V, 3.3V, so 5V, 12V, 3.3V can both correctly indicate electric power starting on the mainboard.
