Embodiment
The PF signal is a discrete type control signal in this computing machine, and it has the effect of two aspects: the one, and the power supply that is used for this computing machine adds electric control; Another effect is to send the PF operational order.The present invention has utilized these two functions just and has innovated, and has formed a kind of signal processing system of PF operational order.
Referring to Fig. 1, the invention provides a kind of signal processing system of PF operational order, this system comprises PF signal input part, division module, filtration module, steering module and locking module; PF signal input part, division module, filtration module and steering module are connected successively; Steering module links to each other with the PF signal input part by locking module.Locking module is a field effect transistor, and filtration module is that the device that wave filter or some can be carried out filter function all is feasible; Steering module is a phase inverter; Division module is a divider resistance.
In addition, system provided by the present invention also can be used for outside X type computing machine is powered, this function is that the outside power supply control module by the signal processing system of PF operational order realizes, outwards power supply control module places between PF signal input part and the division module, and the PF signal input part, outwards power control module and division module connects successively.
Outwards the power supply control module comprises PF signal solid-state switch, relay and power supply; PF signal solid-state switch, relay and power supply connect successively; The PF signal input part inserts PF signal solid-state switch; By relay to externally fed.
Referring to Fig. 2, first effect of PF signal is control PF operation, and PF operation control is the major function of PF signal.The PF signal is connected to outside cabinet+28V, is high under the normality, draws with on+the 15V on the GPI module in X type computing machine, when the PF signal is effective, produces a low pulse that 1S is wide, sends the PF operational order.
Because the PF switch is the switching signal of momentary connection, need this computer-internal that this signal is carried out self-locking and removing, draw dividing potential drop on the PF signal warp+15V with divider resistance, after the dividing potential drop under the normality PF state be 13V, the RC circuit of rear end can be to the effective filtering of undesired signal, and field effect transistor realizes the auto-lock function of signal.
Referring to Fig. 3, the LPF# signal generates the BPF signal after anti-phase, the clear PF signal (CLRPF#) of the latter and software and put the output that PF signal (SETPF#) is controlled PONPF and PFCMD jointly.The logical relation of CPF and control signal PONPF and PFCMD is:
CPF＝！RES&(PFCMD#PONPF)
If when PF go up to produce an effective low pulse signal, LPF# signal step-down, BPF signal be (effectively high) effectively, by trigger control PFCMD signal, make CPF signal effectively (effectively high), the base stage of CCPF useful signal (effectively high) control field effect transistor realizes the self-locking of PF signal.
Put PF effectively when (SETPF#) when software, it is effective to put the PFCMD signal by trigger, this moment the BPF invalidating signal, the CPF signal is effective, the base stage of CCPF useful signal control field effect transistor realizes self-locking.
Putting the CPF signal has the hardware and software dual mode, and hardware produces effective impulse on PF, and software can produce by the mode of putting PF state (SETPF#).After the PF operation was finished, System Cleaning PF finished a PF control from lock signal.The clear CPF signal of software can only make the CPF invalidating signal, the PF state decision that the BPF signal condition is provided by the outside.CPF (CCPF) signal is in case effectively, has only by software and removes or reset, and just can become disarmed state.
Referring to Fig. 4, another effect of PF signal is that X type computing machine is powered.The PF signal is mutually crosslinked with the XX panel, and the PF signaling switch on the XX panel is a solid-state switch, and it is connected to this computing machine by two-wire.Relay conducting after the PF signaling switch closes powers on for this computing machine by external power source.This signal circuit is that the primary source of this computer-internal returns to ground with reference to ground wire.
According to the circuit working principle, adjust the resistance in the RC circuit and the appearance value of filter capacitor, all can change the filter capacity of circuit, capacitance is linearly proportional with the duration of the undesired signal that can filter.According to state among the figure, when electric capacity was 0.1uF, the undesired signal that can filter was the 140us effective width, and when electric capacity was 1uF, the undesired signal that can filter was the 1.5ms effective width.Adjust the width that size of current also can be controlled filtering signal by changing resistance value, but the adjustment of resistance to be considered the proportionate relationship of voltage, guarantees the validity of signal.
Adjust resistance value and filter capacitor value, the time response of adjustable circuit further improves its antijamming capability, but also can cause signal delay simultaneously, will consider to postpone whether can bring negative effect during use.
