It is described further below in conjunction with working principle to shown in Fig. 8:
In the specific implementation process, after key switch SK is placed in the position ON and presses start button SP, the first triode
The base stage of Q1 can be connected to input dc power anode, since the emitter of the first triode Q1 connects DC power cathode, so
When the first triode Q1 base stage and the first triode Q1 emitter between form pressure drop, so that the first triode Q1 be made to lead
It is logical；It is connect later due to the grid of field-effect tube Q with the collector of the first triode Q1, the source electrode connection of field-effect tube Q is defeated
Enter the anode of direct current, therefore, forms pressure drop, field-effect tube Q conducting between the grid and source of field-effect tube Q at this time；On the spot
Be connected between the drain electrode of effect pipe Q and input dc power anode, thus be connected to field-effect tube Q drain electrode and input dc power it is negative
The equal work once electrified of all components between pole, and after the electrification of the coil-end of the first relay K1, the contact two of the first relay K1
End conducting (contact closure), therefore the work package of screening machine connects general supply, thus work once electrified.At this time screening machine integrally it is electric
It starts to work.Later, due to the output end of the first optocoupler U1 and the first triode Q1 collector and emitter and connect, Gu Chang effect
Should be after pipe Q conducting, the input anode end of the first optocoupler U1 is defeated by the 6th resistance R6, first resistor R1 and the first optocoupler U1's
Entering end and form pressure drop, and then makes the output end of the first optocoupler U1 that ground connection be connected, the grid end of field-effect tube Q continues to low level,
To make field-effect tube Q be continuously on state.
And when wanting shutdown, key switch SK is placed in OFF position, since key switch SK is connect with host computer 05, key
Spoon switch SK is placed in meeting after OFF position, and the level signal for being sent into host computer 05 is upper to inform for low level by high level jump
Machine 05 shuts down, and after host computer 05 receives skip signal, will be immediately performed corresponding shutdown programm, when delay procedure therein
Between arrive, can export close machine control signal VOFF, passs machine control signal be low level signal, in the pass machine control signal of host computer 05
After machine control signal is closed in output end output, close machine control signal drag down the first optocoupler U1 positive terminal voltage to 0V, so the
The output of one optocoupler U1 ends.Specific work process is, since field-effect tube Q drain electrode and the pressure drop of field-effect tube pipe Q source electrode are
Definite value, therefore after field-effect tube Q conducting, the voltage value of drain electrode is then fixed, and (field-effect tube conducting resistance is very low, so first end
Pressure drop with second end is almost that 0), the drain electrode of field-effect tube Q connect by concatenated first resistor R1 with the 6th resistance R6
The positive terminal of one optocoupler U1.Later, when host computer 05 exports the company of pass machine control signal to first resistor R1 and the 6th resistance R6
It is low level signal due to closing machine control signal, the positive terminal of the first optocoupler U1 is low level, at this time the first light after contact
Coupling U1 output cut-off, the grid of field-effect tube Q becomes high level from low level, between the grid and source electrode of field-effect tube Q pressure drop be
Zero and end, and then all components of rear end screening machine is made to have a power failure shutdown.
When needing motor 08 to rotate forward, the output of host computer 05 rotates forward control signal, and Vctrl1 is low level, i.e. in Fig. 8
Vctrl1 is low level, and host computer 05 does not export reverse control signal at this time, therefore Vctrl2 is high level.At this time due to
Vctrl1 is low level, therefore the base stage of the second triode Q2 is low level, the second triode Q2 conducting, the anode of the second optocoupler U2
It terminates into high level, the input terminal of the second optocoupler U2 forms pressure drop, the conducting of U2 output end, and the second optocoupler U2 will make the when being connected
One silicon-controlled SC1 conducting, the first silicon-controlled SC1 conducting motor 08 rotate forward, and control motor 08 rotates forward.That is the V1 and V2 in Fig. 8 are short
Connect conducting), control motor 08 rotates forward.Vctrl1, Vctrl2 are low level when host computer 05 exports reverse control signal, at this time
The positive terminal of second triode Q2 conducting, the second optocoupler U2 accesses low level, and the input terminal of the second optocoupler U2 is without pressure drop, the second light
The cut-off of coupling U2 output end, third optocoupler U3 positive terminal access high level, and the input terminal of third optocoupler U3 forms pressure drop, third optocoupler
The conducting of U3 output end, the conducting of third optocoupler U3 output end can make the second silicon-controlled SC2 conducting.Motor is connected in second silicon-controlled SC2
08 reversion.Twelfth resistor R12 and thirteenth resistor R13 is respectively two control machines current-limiting resistances.14th resistance R14
It is respectively two silicon-controlled anti-interference resistance with the 16th resistance R16.First capacitor C1 and the 15th resistance R15 composition point
Peak absorbing circuit come protect the first silicon-controlled SC1 not by spike damage to improve its reliability, similarly, the second capacitor C2 and the tenth
Seven resistance R17 composition circuit come protect the second silicon-controlled SC2 not by spike damage to improve its reliability.
Since in Fig. 8, field-effect tube Q is connected to input dc power V+, to be powered to host computer, detecting plate etc., when defeated
When entering direct current V+ generation short circuit, when short circuit occurs such as host computer, detecting plate, relay coil, the voltage of input dc power V+
What can be dropped is very low, and the voltage of the input terminal of the first optocoupler U1 reduces, so that the output end of the first optocoupler U1 ends, field-effect tube Q
Cut-off, field-effect tube Q stop connection input dc power V+, therefore realize the short-circuit protection effect of input dc power.
