Second step, trigging control no-output, when testing circuit detects that above any one group of output voltage occurs short circuit, send trigger pip, and exported without ﹢ 5VSB output voltage by trigger control circuit control ATX power supply, make its no-output, when testing circuit can't detect above any one group of output voltage occur short circuit time, then do not send trigger pip;
3rd step, time delay, sets time delay, makes it occur of short duration time delay.
4th step, trigging control has output, exports ﹢ 5VSB output voltage after time delay by trigger control circuit control ATX power supply.
After above four steps complete, can realize when keeping inputting not power-off, reach when not disconnecting input voltage when any one group of output voltage of power supply ﹢ 5V, 3.3V, ﹢ 12V and ﹣ 12V tetra-road output voltage of ATX output has short circuit, computing machine can the object of boots.
Further, described testing circuit is for detect by MCUI/O mouth.
Further, described testing circuit is for detect by voltage checking chip.
Further, described testing circuit is for building voltage detecting by discrete component or Trigger Function detects.
In addition, this testing circuit all detects by alternate manner, the testing circuit of existing various detection mode has multiple, can use in this method as long as any one group of output voltage that can realize power supply ﹢ 5V, 3.3V, ﹢ 12V and the ﹣ 12V tetra-road output voltage detecting ATX output occurs short circuit.
Simultaneously, this trigger control circuit also can use various different firing control to realize, as long as can realize sending trigger pip after short circuit having been detected, and exported without ﹢ 5VSB output voltage by trigger control circuit control ATX power supply, make its no-output.
The beneficial effect that the present invention produces is: this method is when keeping inputting not power-off, detection, trigging control no-output, time delay and trigging control is adopted to have output four steps, can realize after any one group of output voltage of power supply ﹢ 5V, 3.3V, ﹢ 12V and ﹣ 12V tetra-road output voltage ATX output being detected occurs short circuit, the ﹢ 5VSB of ATX power supply output can be started automatically, computer motherboard can not be locked, and therefore computing machine does not need again deenergization then can again start shooting; Because solving it by locked problem, realize autoboot, can continuous service, thus some unattended robotization start occasion can be used in, usable range is more extensive, and intelligence degree is higher.
Accompanying drawing explanation
Fig. 1 is a kind of process flow diagram solving the locked method of motherboard power supply short circuit of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail.
The present embodiment, with reference to Fig. 1, a kind ofly solve the locked method of motherboard power supply short circuit, when keeping inputting not power-off, the step of the method is as follows: the first step, detects; Second step, trigging control no-output; 3rd step, time delay; 4th step, trigging control has output.
+ the 5VSB that computer power supply exports, be the accessory power supply of computer power supply, it is supplied to the power supply of computer standby, is mainly supplied to cabinet switch, and network interface card etc. need the energize portions waking computer booting required function up, and after system closedown ,+5VSB still exists.
The first step, detect, described testing circuit is for detect by MCUI/O mouth or by voltage monitoring chip, and whether any one group of output voltage arranging power supply ﹢ 5V, 3.3V, ﹢ 12V and ﹣ 12V tetra-road output voltage of testing circuit detection ATX output has short circuit;
Second step, trigging control no-output, when detecting that above any one group of output voltage occurs short circuit when testing circuit, send trigger pip, embodiment sends a high level or low level for controlling metal-oxide-semiconductor by MCUI/O mouth or by a certain PIN of voltage monitoring chip after circuit not time delay or time delay, triode, the components and parts such as optocoupler, or a certain PIN of MCUI/O mouth or other voltage monitoring chip sends a high level or low level for trigger control circuit after circuit not time delay or time delay, and exported without ﹢ 5VSB output voltage by trigger control circuit control ATX power supply, make its no-output, when testing circuit can't detect above any one group of output voltage occur short circuit time, then do not send trigger pip,
3rd step, time delay, sets time delay, makes it occur of short duration time delay.
4th step, trigging control has output, + 5VSB output voltage is exported by trigger control circuit control ATX power supply after time delay, its embodiment is identical with second step embodiment, namely after circuit not time delay or time delay, a high level or low level is sent for controlling metal-oxide-semiconductor by MCUI/O or by a certain PIN of voltage monitoring chip, triode, the components and parts such as optocoupler, or a certain PIN of MCUI/O mouth or other voltage monitoring chips sends a high level or low level for trigger control circuit after circuit not time delay or time delay, and export ﹢ 5VSB output voltage by trigger control circuit control ATX power supply.
After above four steps complete, can realize when keeping inputting not power-off, reach when not disconnecting input voltage when any one group of output voltage of power supply ﹢ 5V, 3.3V, ﹢ 12V and ﹣ 12V tetra-road output voltage of ATX output has short circuit, computing machine can the object of boots.
In addition, this testing circuit all detects by other modes, the testing circuit of existing various detection mode has multiple, can use in this method as long as any one group of output voltage that can realize power supply ﹢ 5V, 3.3V, ﹢ 12V and the ﹣ 12V tetra-road output voltage detecting ATX output occurs short circuit.
Simultaneously, this trigger control circuit also can use various different firing control to realize, as long as can realize sending trigger pip after short circuit having been detected, and exported without ﹢ 5VSB output voltage by trigger control circuit control ATX power supply, make its no-output.
This method is when keeping inputting not power-off, detection, trigging control no-output, time delay and trigging control is adopted to have output four steps, can realize after any one group of output voltage of power supply ﹢ 5V, 3.3V, ﹢ 12V and ﹣ 12V tetra-road output voltage ATX output being detected occurs short circuit, the ﹢ 5VSB of ATX power supply output can be started automatically, computer motherboard can not be locked, and therefore computing machine does not need again deenergization then can again start shooting; Because solving it by locked problem, realize autoboot, can continuous service, thus some unattended robotization start occasion can be used in, usable range is more extensive, and intelligence degree is higher.
Above content is in conjunction with concrete preferred embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as protection scope of the present invention.
