Description
Technical field
The utility model relates to electronic fields, and in particular to a kind of computer incoming call auto power on device.
Background technique
After current most of computer has a power failure, next caller computer will not Auto Power On, have part computer can send a telegram here from
Dynamic booting, but setting is complex, incoming call needs again after having a power failure for the computer that certain scenes need work for 365x24 hours
It to be manually switched on, such as server, monitoring computer, advertisement computer, data operation computer etc..
Utility model content
To solve the above-mentioned problems, next time, incoming call automatically opened electricity after computer being allowed to have a power failure the utility model proposes one kind
Brain does not need the opening device being manually switched on.
To achieve the goals above, the utility model is achieved through the following technical solutions:
A kind of computer incoming call auto power on device, including relay K1, relay K2, capacitor C1 and USB interface J1；It is described
USB interface J1 includes that power end, power ground, data line D+ and data line D-, the power end are connected with the input of diode D1
End, the output end of the diode D1 are connected with the input terminal of resistance R1, the output end of the resistance R1 be connected with capacitor C1 and
Resistance R2, the resistance R2 is in parallel with capacitor C1 and resistance R3 respectively, and the capacitor C1 connects with the resistance R3, the resistance
R2 and resistance R3 is connected on two ports of triode Q1, and the other end of the triode is connect with the relay K1, institute
It states relay K1 to connect with the relay K2, the relay K2 is connect with computer main board booting contact pin.
Further, the triode Q1 is NPN triode.
Further, the resistance R2 is connect with the ground level of the triode Q1, the collector of the triode Q1 and institute
Relay K1 connection is stated, the emitter of the triode Q1 is connect with the resistance R3.
It further, include switch in the relay K2, the switch is connect with relay K1.
It further, include diode D2 in the relay K1.
Further, the resistance value of the resistance R1 and resistance R2 is 1k Ω.
The utility model computer incoming call auto power on device, the beneficial effect is that:
(1) relay k1 defaults normally closed on state, be equivalent to after power failure mainboard booting contact pin be it is constantly on, when
After next time sends a telegram here, since booting contact pin is in short circuit state in advance, computer is with regard to Auto Power On；
(2) power end of USB interface J1 generates 5V after booting computer, charges to capacitor C1, when the voltage on capacitor reaches
After the conducting voltage of triode Q1, triode Q1 conducting, relay k1 is disconnected, and boot action is completed.
(3) next time, incoming call automatically opened computer after computer can be allowed to have a power failure, and did not needed manually to be switched on, pure hardware circuit, nothing
Software is needed to be arranged, plug and play.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
