Below in conjunction with the drawings and the specific embodiments the present invention is described further.
As shown in Figure 1, be the calcspar of a preferred embodiment of the present invention, be installed on such as on the vehicles such as car, ship, aircraft in order to represent computer A of the present invention, and connect the situation of the power supply 5 and the electric switch 6 of these vehicles.Wherein, power supply of these electric switch 6 these vehicles of bridge joint 5 and electric-control system 8 can start or close this vehicles by key operated this electric switch 6.
This computer A can start its Basic Input or Output System (BIOS) (BIOS) when receiving a starting-up signal, and closes its operating system (OS) when receiving an off signal.More detailed it, this computer A comprises a motherboard 1 and such as computer peripheral device (not shown)s such as CD-ROM device, Hard Disk Drive, displays.
This motherboard 1 comprises the control module group, for example be used to store the non-volatile memory 100 of this Basic Input or Output System (BIOS), be used to constitute a south bridge controller 110, a north bridge controller 120, a central processing unit 130, memory main (not shown) of control and arithmetic core or the like.Wherein, this south bridge controller 110 is responsible for receiving this starting-up signal and off signal.When this south bridge controller 110 is received this starting-up signal, can start this Basic Input or Output System (BIOS) and carry out a series of boot program, to finish the start of this computer A, the selftest (POST) and this operating system is written into the memory main supervisor of for example starting shooting.When this south bridge controller 110 is received this off signal, will close this operating system, just require this operating system to carry out a series of shutdown programm, to finish the shutdown of this computer A.
This motherboard 1 also comprises a power-switching circuit 2, an electric switch circuit for detecting 3, reaches a power switch circuit 4.Wherein:
This power-switching circuit 2 is connected to the power supply 5 of these vehicles via this power switch circuit 4, the electricity that the power supply 5 of these vehicles can be transmitted is from its power input 200 inputs, and convert to and be fit to that those unit use, for example convert the magnitude of voltage that meets under the AXT standard to, and be supplied to those unit respectively from its each power output end 210.Further, this power-switching circuit 2 also can send the ready signal of a power supply from its output terminal 220 and give this south bridge controller 110, represents that this power-switching circuit 2 has been in the state of being ready at present.
The power supply 5 of these power switch circuit 4 these vehicles of bridge joint and the input end 200 of this power-switching circuit 2, and controlled turn-on or cut off the power supply 5 and this power-switching circuit 2 of these vehicles, for example use solid state switch or relay just can reach this purpose.
This electric switch circuit for detecting 3 can be detected the electric switch 6 of these vehicles, and detecting this electric switch 6 when being opened (ON), order about the power supply 5 and this power-switching circuit 2 that this power switch circuit 4 is connected these vehicles through its first control end 30, and send above-mentioned starting-up signal through its second control end 31 and give this south bridge controller 110.This electric switch circuit for detecting 3 also can detect this electric switch 6 when being closed (OFF), order about this power switch circuit 2 cuts off these vehicles after one period stand-by period power supply 5 and this power-switching circuit 2 through its first control end 30, this can use oscillator timer or electrotimer to reach this purpose.Further, this electric switch circuit for detecting 3 is detecting this electric switch 6 when being closed, and sends above-mentioned off signal through its second control end 31 and gives this south bridge controller 110.
Because this electric switch circuit for detecting 3 is when on detection of this electric switch 6 is closed (OFF), will after waiting time, cut off the power supply 5 of these vehicles via this power switch circuit 2, and waiting time is at least greater than the time of normally closing this operating system, therefore, no matter this computer A shuts down via user's operation, or via these electric switch circuit for detecting 3 shutdown, after can both guaranteeing that this operating system is normally closed, this power switch circuit 4 just cuts off the power supply 5 of these vehicles, in order to avoid this computer A improper shutdown situation takes place.Simultaneously, even this operating system can't be closed, as long as crossed after waiting time, this power switch circuit 4 also can cut off the power supply 5 of these vehicles, avoids continuing consuming the power supply 5 of these vehicles.
In addition, this motherboard 1 comprises that also a manual power switch 7 is connected in this south bridge controller 110, in order to produce above-mentioned starting-up signal.
In above-mentioned example, this electric switch circuit for detecting 3 and manual power switch 7 can produce this starting-up signal, and this electric switch circuit for detecting 3 is that the opening according to this electric switch 6 produces this starting-up signal, therefore, this computer A not only can start shooting with manual mode by this manual power switch 7, more can follow the unlatching of this electric switch 6 and Auto Power On.This one makes the function of this computer A Auto Power On by this electric switch 6, show for former technology can't be obtained.Further, this computer A also can shut down automatically along with closing of this electric switch 6 and cut off itself and being connected of the power supply 5 of these vehicles automatically, this one makes automatically shutdown and isolate the function of the power supply 5 of these vehicles automatically of this computer A by this electric switch 6, also be before technology unexistent.
Moreover 3 states that need this electric switch 6 of detecting of this electric switch circuit for detecting do not need to detect the state of this manual power switch 7, and finally just merely send starting-up signal and off signal yet, do not need to wait for the response of this computer A.Therefore, the structure of this electric switch circuit for detecting 3 and relevant part thereof is quite simple, has the unexistent advantage of former technology.
In addition, above-mentioned Basic Input or Output System (BIOS) can comprise further that a plurality of power on mode supply the user of this computer Λ to choose one of them, these a plurality of power on mode comprise a permanent on-mode, one permanent pass pattern, an and memory pattern, when this perseverance on-mode is selected, make this south bridge controller 110 when the starting-up signal of receiving from this electric switch circuit for detecting 3, just start this Basic Input or Output System (BIOS), when this perseverance pass pattern is selected, make this south bridge controller 110 only when the starting-up signal of receiving from this manual power switch 7, just start this Basic Input or Output System (BIOS), and when this memory pattern is selected, make this south bridge controller 110 according to last time power on mode start this Basic Input or Output System (BIOS).The start mode of this soft, hardware collocation of picture also is one of emphasis of technology before the present invention is better than.
In addition, above-mentioned power-switching circuit 2, electric switch circuit for detecting 3, and power switch circuit 4 can be integrated into a power supply changeover device, be used to connect the power supply 5 of these vehicles and a computer that matches.
