Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail.
The present invention realizes the intelligent electric power management function in based on the embedded system controller of PXIe/CPCIe, by the signal that backboard provides for system controller, only carry out simple level and logical transition and realize.
Fig. 1 is PWRBTN# Signal Processing examples of circuits figure among the present invention.As shown in Figure 1, the PWRBTN# signal is the input signal of embedded system controller core processing module, for+3.3VCMOS level feature, the negative edge pulse is effective, promptly can realize that by driving this signal the embedded system controller starts from off-mode.The PWRBTN_C# signal is the signal that provides by in the cabinet back panel connector, and this signal connects the button of can upspringing on cabinet, is to produce the negative edge pulse by the button of can upspringing in the mode of open circuit-ground connection-open circuit at cabinet inside.
In the present embodiment, the PWRBTN_C# signal by resistance R 319 be pulled to+be connected to the PWRBTN# signal end of embedded system controller core processing module by build-out resistor R318 behind the 3.3Vaux, the PWRBTN_C# signal is also by filter capacitor C316 ground connection.Wherein+3.3Vaux is normal 3.3V power supply, its normal 5V power supply that provides by chassis power supply promptly+5Vaux changes generation.+ 5Vaux is the direct supply type that chassis power supply provides, and whether this direct supply is unlocked irrelevant as long as cabinet powers on and just begins to provide with the chassis power supply button.
This implementation has simply effectively satisfied cabinet switch key signal to the signal transmission between the core processing module.When the upspring button on the cabinet be pressed lift again after, trigger the embedded system controller and start from off-mode.Because the power supply of this function is provided by normal 3.3V power supply, as long as chassis power supply powers on and can realize.
Fig. 2 is the treatment circuit exemplary plot between SUS_S3# signal and the PS_ON# signal among the present invention.As shown in Figure 2, the SUS_S3# signal is the output signal of embedded system controller core processing module, for+3.3V CMOS level feature, low level is effective, when core processing module entered holding state, this signal was effective, exactly at the S3 state that uses a computer and use often, be Suspend to RAM (suspending to internal memory) state, be called for short STR.Core processing module only depends under this state+and 5Vaux (normal 5V) powers, power supply still continues as the most necessary power devices such as CPU, internal memory, guaranteeing that data do not lose, and other equipment (south bridge, north bridge etc.) all are in closed condition, and the power consumption of system is extremely low.When system just is waken up, for example the user presses the power knob on the lower case, the power module of cabinet begins to carry out power source conversion, when core processing module receives power source conversion and finishes (PWR OK) signal, learn that the power supply after the conversion has reached suitable operating conditions, this moment, core processing module was waken up, at once reading of data and return to duty before the STR from internal memory.The PS_ON# signal be provide in the cabinet back panel connector be used for enabling chassis power supply output+12V ,+5V ,+3.3V and-control signal of DC power supplys such as 12V, this signal is input signal on back panel connector, + 5V Transistor-Transistor Logic level feature, low level is effective, and chassis power supply just carries out AC except normal 5V to conversion and the output of DC during low level.
The SUS_S3# signal is by a triode device negate in the present embodiment, is pulled to+is connected to behind the 5Vaux signal end of the PS_ON_C# of cabinet backboard by resistance then.Specifically, in practice, three take over base stage connects the SUS_S3# signal by resistance R 312, grounded emitter, collector through connect+insert PS_ON# after drawing on the 5Vaux power supply, realize the function of core processing module managing electrical power, PS_ON# is further by capacitor C 321 ground connection.
After system hibernates, this function guarantees that by+5Vaux power supply this function also can normally realize after system hibernates.
Fig. 3 is PWR_OK Signal Processing examples of circuits figure among the present invention.As shown in Figure 3, the PWR_OK signal is the input signal of core processing module, for+3.3V CMOS level feature, high level is effective.Be exactly that notice core processing module power supply has reached suitable operating conditions when PWR_OK is effective, core processing module is given the power supply of correlation function power supply by power switch.The PWR_OK_C signal is the signal by reflection cabinet direct supply duty in the cabinet back panel connector, this signal is output signal in back panel connector, + 5V Transistor-Transistor Logic level feature, high level is effective, that is to say, when being output as high level, all are normal for the DC power supply that the expression chassis power supply provides, and core processing module can relievedly be used.
Adopt a duotriode in the present embodiment, draw on being undertaken by different power supply signals here and not only realized level conversion, guaranteed that also the signal logic relation remains unchanged, and has realized the function of power management effectively.Specifically, PWR_OK_C by resistance R 320 be pulled to+insert the two-way triode by build-out resistor R315 behind the 5V, carry out the level conversion of TTL by the two-way triode to CMOS, carry out the level conversion of TTL by the two-way triode to CMOS, the assurance logical relation is constant, and then by resistance R 313 be pulled to+be connected to the PWR_OK signal end behind the 3.3V.The collector C1 of first order triode inserts the base stage B2 of second level triode in the two-way triode, and the base stage B1 of first order triode meets PWR_OK_C, emitter E 1 ground connection, and the collector C2 of second level triode meets PWR_OK, emitter E 2 ground connection.In order to guarantee the stable of two-way triode signal, the collector of first order triode is pulled to+inserts behind the 5Vaux again the base stage of second level triode by resistance.The reason of the access+5Vaux of this place is that when guaranteeing that the main power supply of cabinet does not come up, the PWR_OK signal is low, i.e. disarmed state.
In sum, more than be preferred embodiment of the present invention only, be not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
