The other end is grounded.
The specific course of work and principle are as follows:
MCU is protected to work normally.
It is whole by diode D5 as the b point of the position of magnetic pole rotation charge coil of flywheel also senses positive voltage
After shape, using in diode D6 energy storage to Ignition capacitor C3；The c point of trigger winding also induces voltage waveform at the same time,
After rectifier diode D2 rectification, then by the filtering processing circuit being made of R4, R5, C2, D4, by first voltage signal
A is input to the GP1 of MCU, and MCU revolves the waveform for the adjacent first voltage signal (Wave A in figure) sampled that turns around according to flywheel
Interval time knows that current flywheel revolves the periodic quantity T to turn around；
GP1 incudes wave A first, with the rotation of flywheel position of magnetic pole, finally incudes tertiary voltage signal (wave in figure
C)；With the rotation of flywheel, the d point of trigger winding also incudes positive second voltage signal B, after also passing through rectification and filtering
It is input to the GP5 foot (Wave B in figure) of MCU.
MCU is according to the interval received between input signal Wave B and Wave C, and acquisition time value t, then MCU is according to journey
Sequence setting needs ignition angle requirement, carries out calculating the acquisition correct igniting demand moment using t, when MCU internal clocking
The spark delay moment reach after, MCU by GP0 export ignition control signal, by resistance R6, R7 control Q1 be connected, at this time it
Before be stored in electric energy on capacitor C3 and carry out abrupt release, the curent change of moment passes through and generates high pressure after step-up coil group and use
In igniting, make engine operation.
The charge control module being wherein made of resistance R11, R12 and triode Q3, when flywheel rotation speed is lower,
The GP4 mouth of MCU exports low level signal, is not turned on Q3, and two voltage waveforms of charge coil a point induction are input to by Q2
C4 energy storage guarantees that MCU has enough voltage VDD when low speed, guarantees MCU reliably working.
When MCU recognizes revolving speed greater than 5000RPM, because the vdd voltage of MCU has guaranteed that MCU is worked normally enough,
GP4 exports high-level control signal (see the GP4 waveform of Fig. 3) in advance at this time, controls triode Q3 by resistance R11, R12 and leads
It is logical, to turn off triode Q2；So after charge coil a point inductive waveform arrives, because triode Q2 is in an off state,
So not to C4 charging energy-storing, so the induced voltage of coil a point does not reconnect the load circuit of charging C4, so that a point incudes
Waveform is in light condition, and the amplitude of induced voltage is promoted, and the voltage amplitude of the induction point b of corresponding charge coil is also mentioned
It rises, to increase the electric energy stored on capacitor C3, the ignition energy of high speed may finally be made to promote 10% or so.
After the first inductive waveform of charge coil a point, MCU exports low level control signal, shutdown three by GP4
Pole pipe Q3 charges to capacitor C4 by Q2 control so as to the subsequent induced voltage of charge coil a point, is guaranteeing MCU just
Normal operating voltage.
And the flywheel that above-mentioned T is represented rotates a circle 360 ° of times needed, above-mentioned t represents the flywheel for trigger winding
Upper magnetic pole rotates to the time that the pole S needs from the pole N, rotates to N ° of the rotation angle of the pole S mechanically generally 60 ° or so from the pole N,
So there are the phase ratios in actual machine, such as 60 °/360 °=1/6 by T and t, when flywheel subtracts when carrying out air inlet compression travel
Under speed very serious situation, instantaneous speed suppression ratio is more serious, and the value of t just will increase, so the ratio with T will become larger,
MCU can identify whether the current transient speed of flywheel sharply declines, and decline by the ratio comparison of the two time at this time
Amplitude exported by ignition control mouth GP0 without igniting, it is therefore prevented that flywheel rotation to start anti-recoil program setting
Abnormal ignition under abnormal conditions.
Compared to traditional circuit, the present invention is individually designed to be provided the power supply circuit of VDD for MCU and provides calculating input
Trigger circuit.Individually trigger winding design simultaneously, it is ensured that the input signal into MCU is more accurate, improves biography
The VDD that powers simultaneously on system circuit shine at phase offset, provide accurate benchmark for the high-precision ignition control of MCU control.
The present invention samples energy storage by the voltage waveform that charge coil incudes and provides the MCU VDD worked normally, because of charging
Coil-induced voltage energy is strong, it is ensured that magnetic flywheel can generate enough voltage when compared with low speed rotation to be ensured
The normal work of MCU.Simultaneously in magnetic flywheel high speed rotation, the normal work of the fully sufficient VDD of the voltage for induction of charging, at this time
MCU controls the on-off of triode Q3 by GP4, adjusts the voltage value of charge coil to VDD；
By controlling the charge closing of Q2, the energy that charge coil can be made to incude is used to generate by capacitor C3 energy storage high
Pressure point fire, test data show to be arranged when magnetic flywheel high speed rotation by the adjusting of MCU GP4, high-pressure side can be generated
Ignition energy promotes 10%, increasing ignition performance.
Cooperate the design of the control circuit, it is ensured that the good low-speed performance of igniter, the low speed for improving engine open
Dynamic performance, while high-precision ignition angle can guarantee the stability of engine idling.
