For capacitor C11.Schmidt circuit F11 is that it is same therefore, in embodiment to control pulse M1 and switching pulse P1 with phase Schmidt circuit
Phase.The input terminal of a termination Schmidt circuit of capacitor C11, i.e. the input terminal A3 of F11, other end are connected to publicly.
In Fig. 7 embodiment, Schmidt circuit F11 is to control pulse M1 (A4 point in Fig. 7) with phase Schmidt circuit and directly connect
It is connected to the enabled control terminal of tri-state gate T11, tri-state gate T12, tri-state gate T11, tri-state gate T12 are respectively that low level, high level make
It can be effective.The high and low level of control pulse M1 controls tri-state gate T12 respectively and is in working condition, is illegal state, controls pulse M1
High and low level control respectively tri-state gate T11 be illegal state, be in working condition.It is controlled the control of pulse M1, tri-state gate
In T11 and tri-state gate T12 always one in state is in working condition, it is illegal state state that another, which is in,.Work as tri-state
When door T11, tri-state gate T12 use the enabled effective or high level of low level to enable effective device simultaneously, one of them
It is controlled by the inversion signal of control pulse M1.
Fig. 8 is the switching pulse and control impulse waveform of anti-interference unit embodiment.In Fig. 8, P1 is switching pulse, and M1 is control
Pulse processed, when P1 low level is normal negative broad pulse, A3 point current potential is consistent with A1 point low level current potential in Fig. 7, and M1 is low
Level, tri-state gate T11 are in working condition, and the A1 level point of output is consistent with A0 point；T12 is illegal state, is exported as high resistant
State.The high level of positive burst pulse 11 charges to capacitor C11 by charging resistor R11, increase A3 point current potential；Due to burst pulse 11
Width be less than time T1, A3 point current potential is still below the upper limit threshold voltage of Schmidt circuit F11 at the end of burst pulse 11, because
This, M1 is maintained low level, and tri-state gate T11 maintenance is in working condition；At the end of burst pulse 11, A1 point become again low level and
Make capacitor C11 repid discharge by repid discharge diode D11, keep A3 point current potential consistent with A1 point low level current potential, restores extremely
Burst pulse 11 arrive before state, anti-interference ability restored rapidly, when followed by there is continuous positive narrow pulse interference
When signal, can equally it filter out.Positive burst pulse 12, positive burst pulse 13 width be respectively less than time T1, therefore, work as burst pulse
12, at the end of each of burst pulse 13, M1 is maintained low level, and A1 point becomes low level and again by repid discharge two
Pole pipe D11 makes capacitor C11 repid discharge, keeps A3 point current potential consistent with A1 point low level current potential.
Pulse 14 is normal positive broad pulse, and for P1 when maintaining high level time to reach T1 after rising edge 20, A1 point is high
Being charged by charging resistor R11 to capacitor C11 for level, makes A3 point current potential rise the upper limit threshold for reaching Schmidt circuit F11
Voltage, Schmidt circuit F11 output M1 become high level from low level at rising edge 25, make tri-state gate T11 illegal state,
T12 is in working condition, and the A2 level point of output is consistent with A0 point；The high level of A2 point is made by quick charge diode D12
Capacitor C11 quick charge keeps A3 point current potential consistent with A2 point high level current potential, and M1 is maintained high level.
The low level of negative burst pulse 15 discharges to capacitor C11 by discharge resistance R12, declines A3 point current potential；Due to narrow
The width of pulse 15 is less than time T2, and A3 point current potential is still higher than the lower limit threshold of Schmidt circuit F11 at the end of burst pulse 15
Voltage, therefore, M1 are maintained high level, and tri-state gate T12 maintenance is in working condition；At the end of burst pulse 15, A2 point becomes again
High level and capacitor C11 quick charge is made by quick charge diode D12, makes A3 point current potential and A2 point high level current potential one
Cause, restore to burst pulse 15 state before arriving, anti-interference ability restored rapidly, when followed by have continuously bear it is narrow
When pulse interference signal, can equally it filter out.Width when being respectively less than of negative burst pulse 16, negative burst pulse 17, negative burst pulse 18
Between T2, therefore, at the end of each of burst pulse 16, burst pulse 17, burst pulse 18, M1 is maintained high level, A2 point weight
Newly become high level and capacitor C11 quick charge is made by quick charge diode D12, makes A3 point current potential and A2 point high level electricity
Position is consistent.
P1 indicates that P1 has a normal negative broad pulse, A2 when maintaining low level time to reach T2 after failing edge 21
The low level of point discharges to capacitor C11 by discharge resistance R12, and the decline of A3 point current potential is made to reach the lower limit of Schmidt circuit F11
The output M1 of threshold voltage, Schmidt circuit F11 becomes low level from high level at failing edge 26, makes tri-state gate T11 work
Make state, T12 is illegal state；The low level of A1 point makes capacitor C11 repid discharge by repid discharge diode D11, makes A3
Point current potential is consistent with A1 point low level current potential, and M1 is maintained low level.19 width of negative broad pulse of P1 is greater than T2, in negative broad pulse
When maintaining high level time to reach T1 after 19 rising edge 22, M1 becomes high level from low level at rising edge 27.
Anti-interference unit is by the burst pulse 11 in P1 signal, burst pulse 12, burst pulse 13, burst pulse 15, burst pulse 16, narrow arteries and veins
Punching 17, burst pulse 18 all filter out, and positive broad pulse 14, negative broad pulse 19 can pass through, and make to occur accordingly just in M1 signal
Broad pulse 23 and negative broad pulse 24.The same phase of pulse M1 and switching pulse P1 is controlled, and 14 rising edge of broad pulse exported is than input
Broad pulse 14 rising edge lag time T1, failing edge lag time T2.
Burst pulse 11, burst pulse 12, burst pulse 13 are positive burst pulse, and wherein burst pulse 11 is disturbing pulse, burst pulse 12,
Burst pulse 13 is continuous switch contact Vibrating pulse.Time T1 is the positive narrow pulse width of maximum that anti-interference unit can filter.
T1 is by charge constant, the upper limit of the high level current potential that tri-state gate T11 is exported, low level current potential and Schmidt circuit F11
Threshold voltage joint effect.Under normal conditions, the high level current potential and low level current potential of tri-state gate T11 output are definite value, therefore,
The value for adjusting T1 can be carried out by changing the upper limit threshold voltage of charge constant or Schmidt circuit.In Fig. 7, fill
Electrical time constant is the product of charging resistor R11 and capacitor C11.The positive pulse signal that the anti-interference unit allows width to be greater than T1
Pass through.
