Problems solved by technology

However, when any of the four output voltages of +5V, +3.3V, +12V and -12V is short-circuited in the existing computer power motherboard, as long as the ATX output power supply has +5VSB output, the computer motherboard will be locked. Dead, unable to reboot, until the +5VSB voltage output restarts before rebooting.
In this way, after any one of the four output voltages of the ATX output power supply +5V, +3.3V, +12V and -12V is short-circuited, it cannot be restarted or applied to a certain system without disconnecting the input voltage. In some unattended automatic startup occasions, the computer system cannot continue to work

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] In this embodiment, refer to figure 1 , a method for automatically restarting the output of an ATX power supply. In the case of keeping the input uninterrupted, the steps of the method are as follows: the first step, detection; the second step, trigger control without output; the third step, delay; the third step Four steps, the trigger control has an output.

[0024] The +5VSB output by the computer power supply is the auxiliary power supply of the computer power supply. It provides power for computer standby, mainly for chassis switches, network cards and other parts that need to wake up the functions required for computer startup. After the system is shut down, +5VSB still exists.

[0025] The first step is to detect, the detection circuit is to detect through the MCU I / O port or through the voltage monitoring chip,...

Abstract

The invention discloses a method for automatically restarting ATX (AT Extended) power supply output in the field of computer power supplies. Under a situation that input is kept without power failure, the method comprises the following steps: (1) detection, (2) trigger control without output, (3) delaying and (4) trigger control with output. Through the adoption of the method disclosed by the invention, under a situation that input is kept without power failure, the ATX power supply output +5VSB can be automatically restarted and a computer motherboard cannot be locked up after any output voltage of +5V, +3.3V, +12V and -12V output voltages of the ATX output power supply is short-circuited; therefore, the computer can be restarted without switching off the power supply again; and as a problem of lockup is solved and automatic restart is achieved, the method disclosed by the invention can be used in a plurality of unmanned automatic startup places, and the use range becomes wider.

Description

[0001] technical field [0002] The invention relates to the field of computer power supplies, in particular to a method for automatically restarting the output of an ATX power supply. [0003] Background technique [0004] In the prior art computer working power supply, when any one of the four output voltages of the ATX output power supply +5V, +3.3V, +12V and -12V is short-circuited, the + 5VSB is persistent, that is, there is +5VSB output when the power supply is input. However, when any of the four output voltages of +5V, +3.3V, +12V and -12V is short-circuited in the existing computer power motherboard, as long as the ATX output power supply has +5VSB output, the computer motherboard will be locked. Dead, unable to restart, until the +5VSB voltage output restarts before restarting, that is, you need to disconnect the power supply of the motherboard and then reconnect the power supply before restarting. In this way, after any one of the four output voltages of the AT...
