Problems solved by technology
However, most industrial control single-board computers or small computer motherboards are only powered by 4PIN or 2PIN, and the motherboard does not have a PS-ON feedback signal, so it is impossible to automatically switch the machine on and off and turn off the ATX power supply, only by manually shorting the GND and PS of the ATX power supply -ON signal to turn on the ATX power supply, manually disconnect the GND and PS-ON signals or turn off the ATX switch to turn off the ATX power supply

Embodiment 1
[0011] see figure 1 , the computer mainframe that can switch ATX power supply automatically, is characterized in that: comprise no PS-ON feedback signal mainboard, the ATX power supply that does not have PS-ON feedback signal mainboard power supply, manual press switch SB and relay; Said relay KM is connected on mainboard Above, when the main board is energized, the relay KM is energized and its normally open contact KM1 is closed; the manual push switch SB is electrically connected to the ATX power supply, and when the manual push switch SB is pressed, the ATX power supply starts and supplies power to the main board; The normally open contact KM1 is connected in parallel with the manual push switch SB.
[0012] In this embodiment, the relay KM is connected between the ground terminal GND1 of the motherboard and the positive terminal of the power supply. The manual push switch is connected between the PS-ON signal terminal of the ATX power supply and the ground terminal GND2....

The invention discloses a computer host capable of automatically switching on / off an ATX (advanced technology extended) power supply. The computer host comprises a mainboard free of PS-ON (power supply-on) feedback signal, an ATX power supply free of PS-ON feedback signal mainboard power supply, a manual pressing switch SB and a relay, wherein the relay KB is connected on the mainboard, when the mainboard is electrified, the relay KB is electrified and a normally-opened contact KM1 thereof is closed; the manual pressing switch SB is electrically connected with the ATX power supply, when the manual pressing switch SB is pressed, the ATX power supply is started to supply power to the mainboard; and the normally-opened contact KM1 is parallelly connected with the manual pressing switch SB. The computer host capable of automatically switching on / off the ATX power supply can realize automatic switching on and switching off of the ATX power supply of the mainboard free of the PS-ON feedback signal. When the manual pressing switch SB is pressed down by a user, the ATX is automatically switched on to supply power to the mainboard, and when an operation system is shut down by the user, the ATX power supply is automatically switched off.
Description
technical field [0001] The invention relates to an ATX power supply automatic switch device applied to a computer mainframe with no PS-ON feedback signal main board, in particular to a computer mainframe capable of automatically switching the ATX power supply. Background technique [0002] At present, most of the mainboards of personal computers on the market are 20PIN or 24PIN ATX power sockets, and the mainboards have PS-ON feedback signals and are connected to the power sockets. In this way, after the user presses the power-on button on the motherboard case, the motherboard will feed back a low-level PS-ON signal and hold it, thereby turning on the ATX power supply to supply power to the motherboard; when the user shuts down the computer operating system, the motherboard will feedback a high-level PS-ON signal signal, thereby turning off the ATX power supply. However, most industrial control single-board computers or small computer motherboards are only powered by 4PIN o...
