Description
Technical field
The present invention relates to a kind ofly prevent that maloperation from causing the method for main frame power-off illegally, specifically, but is to utilize the control circuit of a kind of prolongation switch key unused time of software setting to prevent that maloperation from causing the main frame power-off illegally.
Technical background
At computer host system and need come with electronic switch in all application of control system power supply, the point that all can need to use an impulse type touches switch and triggers start or shut down event.The shutdown mode of such switch is divided into two states at present: first kind is the shut down event that can make an immediate response behind the trigger switch, can trigger the ACPI event notice system simultaneously and carry out normal shutdown.Second kind is directly shutdown of hardware 4 seconds, promptly pins switch and can not send shutdown command to operating system after 4 seconds and directly cut off the power supply.
First kind is on-off mode the most commonly used, and this shutdown mode can trigger the shut down event reporting system of ACPI and normally close, and can not cause any infringement to system.If but in a single day this kind mode has triggered power switch unintentionally, then may cause system to close automatically, the current work of handling may be stopped by force.
Second kind is pure hardware switch, and this shutdown mode need be pinned power switch just can the Shutdown Hosts power supply after 4 seconds.Can not occur owing to triggering the situation that system that power switch causes closes automatically unintentionally.But this circuit can triggering system shutdown command, can't normally close by reporting system, but directly cut-out is cut off the power supply to main frame.This kind behaviour does and might cause the system crash thing to take place at any time.
Summary of the invention
The purpose that the present invention will solve provides and a kind ofly prevents that maloperation from causing the method and the device of host computer system power-off illegally; it can be in conjunction with the advantage of present two kinds of shutdown modes; satisfy and prevent that maloperation from causing the function of host computer system power-off illegally and protection system; utilize software to realize enabling or forbid this function, strengthened the practicality of this method and the design of hommization.

Above-mentioned power switch is that the point of impulse type touches switch.
Application prevents that maloperation from causing the method for the device of host computer system power-off illegally, and it mainly may further comprise the steps:
1. with the IO address space release of super input-output device; Enter the expanded function pattern;
2. select logical DOS drives;
3. will specify the pin function setting is general input/output function;
4. set and specify GPIO Pin functional definition to be output;
5. the IO interface with super input-output device links to each other with control circuit;
6. set the GPIO Pin output state of appointment; Forbid or enable this control circuit;
7. withdraw from the step of expanded function pattern.
After adopting said apparatus and method, advantage and effect that the present invention had are: method of the present invention is utilized delay circuit and the switching signal of outside input and the interrelated logics such as demand of software set, judge whether this time shutdown behavior is the normal shutdown behavior, thereby play the effect that prevents maloperation.The logic that powers on involved in the present invention can satisfy the switch control requirement of main flow main frame, can solve the problem that maloperation causes host computer system to shut down and cut off the power supply automatically effectively.But software is enabled or is forbidden and makes the hommization more of this function.

Embodiment:
But below in conjunction with accompanying drawing to a kind of software arrangements of the present invention, to prevent that maloperation from causing the method for host computer system power-off illegally to be elaborated as follows:
Input has certain requirement to switching signal at host computer system power switch control section commonly used, all is the safety shutdown that realizes host computer system with an impulse type level as the switching signal of host computer system, this signal can trigger host system software when host computer system was opened shut down event usually.
As shown in Figure 1, a kind ofly prevent that maloperation from causing the device of host computer system power-off illegally, comprise and cooperate host computer system 1 to use, wherein: it comprises software module 2, power switch 3 and control circuit 4, software module 2 is installed in the host computer system 1, this control circuit 4 is connected between host computer system 1 electronic switch input end and the power switch 3, and output terminal directly links to each other with the input end of host computer system 1 electronic switch.
Consult control circuit shown in Figure 2, above-mentioned 4 and comprise delay circuit 41 and logic judging circuit 42, it embeds Basic Input or Output System (BIOS) by software code or application software sets whether need to enable delay function.
The above-mentioned software module of passing through embeds BIOS (Basic Input or Output System (BIOS)) or application software and sets whether to need to enable delay function be that GPIO (general input and output) output able to programme that utilizes main frame I/O chip cooperates the logical and circuit.
Above-mentioned delay circuit needs the parameter regulation circuit of Closing Switch button time length for can realize shutting down the time.
Above-mentioned delay circuit 41 is 74LS 123 integrated circuit 411 and resistance 412 and electric capacity 413 formations for model.
The input end of above-mentioned logic judging circuit 42 links to each other with the general input/output port of host computer system Super IO (super input and output).
Above-mentioned logic judging circuit comprises the logical OR circuit that is used for judging whether into the shutdown behavior of normal running.
Above-mentioned power switch 3 touches switch for the point of impulse type.
The Soft_CRTL signal is Super IO GPIO output among Fig. 2; 5VSB is 5V standby (Standby) voltage, and VCC5 is the standard 5V voltage after host computer system powers on;
Start process: do not have only 5VSB that voltage is arranged before host computer system powers on, be defaulted as+5V, 5V is 0 current potential; When outside input was closed, so be 0 because VCC5 is the output of 0 current potential U1, U2 and Super IO, pulse signal that is equal to outside input of U3 logical OR output triggered host computer system and powers on, starts shooting;
Shutdown process: when outside input SW1 is closed, wait the U1 that coexists (delay circuit) A end (PWR_SW-), U1 Q end (DELAY_OUT) can be according to CEXT﹠amp simultaneously; Rectangle square wave of delay time output that REXT/CEXT RC value is set is that 5s is the upwards rectangle square wave of saltus step of an exportable 5s as setting value; Logic relation picture as shown in Figure 3.
GPIO Pin output that can be by software control main frame Super IO when software need be enabled this function, and be set and be " 1 " (high level); Need forbid this function when software is that the available software control GPIO that crosses is output as " 0 " (low level); The logical relation synoptic diagram is respectively as Enabled Delay Control among Fig. 4 and Disabled Delay Control.
But the complete function that the anti-misoperation of final realization software arrangements causes host computer system to be closed.The logical relation synoptic diagram is respectively shown in Fig. 5 (Enabled Delay Control) and Fig. 6 (Disabled Delay Control).
Fig. 7 is the compilation identifying code of the inventive method.
In actual applications can according to actual conditions adjust switch (SW) when closed the state and the output phase of U1 output terminal or starting-up signal (PWRBTN#) is carried out oppositely (logic NOT) processing satisfies actual requirement.
The above only is a kind of application mode of the inventive method, not in order to limit the inventive method.
