Description
Technical field
The invention belongs to computer application field, relate to a kind of main frame and display linked switch technology specifically.
Background technology
At present, the power switch PWR-SW of the main frame of computing machine and display generally is independently, generally is to open display earlier when using a computer, and opens main frame then; Generally be first Shutdown Hosts when stopping using computing machine, and then close display.The independence of the power switch PWR-SW of the main frame of simultaneous computer and display also exists other advantage: as when computer run during in some operation that does not temporarily need the people to keep an eye on, the power supply that can close display is used for energy-conservation, as downloads large software from the Internet.
When the main frame of current computer shut down, what display entered automatically was dormant state, must use the power switch PWR-SW of display to close display; Display for the power switch PWR-SW that adopts non-contact switch, after display is closed, the power supply of display only exists standby voltage CRT_5VSB (when in a single day the display ac input end has the alternating current of 220V, accessory power supply is just started working, output+5V supplies with the working power that display ON/OFF circuit etc. under off-mode needs); For the display power supply switch P WR-SW that adopts non-contact switch, click primary power source switch P WR-SW (power switch PWR-SW connects once) during use, display opens or closes.
The independence of the power switch PWR-SW of the main frame of current computer and display also exists shortcoming: the user needs 2 operations just can finish the action of start, shutdown, and this operation must be conscious, otherwise just might exist that main frame has cut out and display is forgotten and closed the phenomenon that causes waste electric power owing to carelessness.Granted publication number is operated for 1 time and just can be finished computer booting for " control computer main frame with display the method and the control device thereof of switch " simultaneously patent of CNl235115C has solved the user, the action of shutdown, because of its open and close of adopting the power supply (Vcc) on the sampling computer motherboard to come synchronization indicator, so having the leading display of the main frame of computing machine opens, can not complete observation arrive the host-initiated process, simultaneously because of removing the power switch PWR-SW on the display, when computer run when temporarily not needing on the observation display content, the power supply that can not close display is energy-conservation.
Known from institute, any machine open/close method of main frame all is low and high ATX (BTX) power supply of realizing opening or closing computing machine of control pin Pin 14 (be power supply starting signal PS-ON or the be called power on/off signal PS-ON) signal by control computer motherboard power supply interface; PS-ON control circuit in ATX (BTX) power supply of the control pin Pin 14 of computer motherboard power interface and computing machine is connected, the PS-ON control circuit is accepted the control from " PS-ON " signal on the computer motherboard, when " PS-ON " signal during less than 1 volt (low level), open ATX (BTX) power supply of computing machine, main frame is opened, when " PS-ON " signal during greater than 4.5 volts (high level), the ATX that shuts down computer (BTX) power supply, main frame shutdown; The ATX that shuts down computer described here (BTX) power supply is meant ATX (BTX) the power supply standby of computing machine, ATX (BTX) power supply that is computing machine only exists the standby voltage ATX_5VSB of accessory power supply (when in a single day the power supply ac input end of main frame has the alternating current of 220V, accessory power supply is just started working, output+5V, voltage supply with the inner part of computer motherboard will keep working chip under off-mode).
The ATX of computing machine (BTX) power supply abbreviation computing machine () power supply or host power supply.
