The invention provides the power on/off system that a kind of remote infrared is controlled, as shown in Figure 1, comprise that infrared light the infrared remote receiver 2 that produces the first low level signal, this first low level signal of reception that is connected with infrared remote receiver 2 that Infrared remote controller 1, reception Infrared remote controller 1 are sent latch and produce the latch 3 of latch signal, are connected according to this latch signal, control the power-supply controller of electric 4 of general supply and accessory power supply with latch 3.Wherein, comprise+12VSB of accessory power supply and by this+convert+5VSB of 12VSB and+3.3VSB.In addition, Infrared remote controller 1 is provided with and triggers the button (scheming not shown) that this Infrared remote controller 1 is sent infrared light.
In the power on/off system of controlling at remote infrared of the present invention, Infrared remote controller 1 is independent, and infrared remote receiver 2, latch 3 and power-supply controller of electric 4 are all arranged on computer main board.
As shown in Figure 2, be the infrared transmitting circuit figure of Infrared remote controller 1, Tx is push button signalling; Q2 is NPN triode; D1 is the infrarede emitting diode that sends infrared light; R2 and R3 are current-limiting resistance, for the protection of circuit; Vcc is power supply, for D1 provides power supply.This circuit is when pressing keys, is communicated with Tx and Vcc, and making Vcc is that D1 powers and sends infrared light.
As shown in Figure 3, be the infrared receiving circuit figure of infrared remote receiver 2, Q4 is phototriode, Q1 is PNP triode, plays on-off action; Q3 is NPN triode, plays the effect of amplification and switch; R4, R5, R6 are current-limiting resistance, for the protection of circuit; Rx sends the first low level signal for receiving after infrared.On Q4, receive infrared ray, Rx is dragged down into the first low level signal by original high level.
As shown in Figure 4, the circuit diagram of latch 3, the first low level signal by Rx, is latched on latch 3, and is exported by V_ON, and V_ON signal is stable electric signal, and every pulse of Rx, and V_ON changes once with regard to low and high level.Wherein, latch (Latch) is a kind of storage unit circuit of paired pulses level-sensitive, can be under the effect of specific input pulse level change state; Latch, exactly that signal is temporary to maintain certain level state.Detailed process is: the first low level signal receiving from Rx, and after latching, what V_ON exported is low level signal, what next V_ON exported is high level signal, according to this circulation.
As shown in Figure 5, the power control circuit figure of power-supply controller of electric 4, + VCC12IN_ADP is the input general supply of outer bound pair computer main board, + VCC12_IN is accessory power supply, + VCC12SB(+12VSB), accessory power supply+VCC5SB(+5VSB) ,+VCC3.3SB(+3.3VSB) all by+12VSB, converted; Whether the low and high level decision+VCC12IN_ADP of V_ON signal is communicated with+VCC12_IN; Q134 is P raceway groove mos pipe, and Q135 is N raceway groove mos pipe; L9 inductance is filtering clutter effect; PD1 is TVS pipe, plays static electricity on human body and the anti-lightning strike effect of preventing, protection mainboard.
As shown in Figure 6, the circuit diagram of time delay automatic boot circuit ,+VCC5AL is accessory power supply ,+VCC5VSB is converted by+VCC12_IN; PM_RSMRST_NR462 is the reset signal that south bridge sends, and after accessory power supply+VCC12_IN powers on, can send this signal, and this signal drags down AUTO_BOTTON_N signal, thereby completes Auto Power On.In addition, due to after+VCC12SB powers on, just can send PM_RSMRST_NR462 signal, therefore, also play the time delay from remote keying to shutdown; Q22 is N raceway groove mos pipe, and Q21 is NPN triode, is all the effect of playing switch.
Below in conjunction with Fig. 2-7, the start process of power on/off system of the present invention is described in detail.Because Intel has a successively requirement to electrifying timing sequence, in order to meet this requirement, power on/off system also comprises with power-supply controller of electric 4 and being connected for the time delay automatic boot circuit 5 of time delay Auto Power On.
At the button of pressing Infrared remote controller 1, arrive the first low level signal of the Rx generation of infrared remote receiver 2, switching on and shutting down process is just the same, and switching on and shutting down difference key is that latch 3 has received after the first low level signal, can produce high level signal and low level signal successively; As while being high level signal, power-supply controller of electric 4 is for opening general supply and accessory power supply; As while being low level signal, power-supply controller of electric 4 is for closing general supply and accessory power supply.Switching on and shutting down process specifically describes as follows:
The detailed process of start is: (1) presses the button in Infrared remote controller 1, and Tx and Vcc connect, the conducting of triode Q2 emitter and collector, and infrarede emitting diode D1 sends infrared light (shown in Fig. 2); (2) phototriode Q4 receives the infrared light that D1 sends, the base stage of PNP triode Q1 is dragged down, then the base stage of NPN triode Q3 is drawn high, and the collector and emitter of triode Q3 is switched on, and Rx is dragged down into the first low level signal (shown in Fig. 3) by original high level; (3) this first low level signal, after latch, is stable into high level signal always, and the name of this signal is shown in V_ON(Fig. 4); (4) V_ON is drawn as high level signal, and the drain electrode of Q135 is pulled to low, the drain electrode of Q134 and source electrode conducting, and+VCC12IN_ADP is communicated with+VCC12_IN, and adapter out-put supply is communicated with (shown in Fig. 5) with motherboard power supply; (5) as accessory power supply+VCC12_IN(+VCC12SB) power on after, south bridge energising, sends PM_RSMRST_NR462 high level signal, thereby make NMOS pipe Q22 conducting, NPN triode Q21 conducting, drags down (shown in Fig. 6) by AUTO_BOTTON_N signal, thereby completes start.
Below in conjunction with Fig. 2-5 and Fig. 8, the shutdown process of power on/off system of the present invention is described in detail.At this, power-supply controller of electric 4 is for closing general supply and accessory power supply.
Shutdown detailed process is: (1) presses the button in Infrared remote controller 1, and Tx and Vcc connect, the conducting of triode Q2 emitter and collector, and infrarede emitting diode D1 sends infrared light (shown in Fig. 2); (2) phototriode Q4 receives the infrared light that D1 sends, the base stage of PNP triode Q1 is dragged down, then the base stage of NPN triode Q3 is drawn high, and the collector and emitter of triode Q3 is switched on, and Rx is dragged down into the first low level signal (shown in Fig. 3) by original high level signal; (3) this first low level signal, after latch, is stable into low level signal always, and the name of this signal is shown in V_ON(Fig. 4); (4) V_ON is drawn as low level signal, the drain electrode of Q135 is pulled to height, the drain electrode of Q134 and source electrode cut-off, + VCC12IN_ADP and+VCC12_IN disconnect, be that adapter out-put supply and mainboard primary power disconnect, + VCC12SB ,+VCC5VSB, all power down of+VCC3.3VSB (shown in Fig. 5), thus reach the effect of closing general supply and accessory power supply.
