The storage end of piece machine control circuit is connected by cable with outer memory module U3, and the instruction warning end of single chip machine controlling circuit is led to
Cable is crossed with LED light to be connected.
In Fig. 1, bar 5 is passed through among induction coil 4, the binding post of induction coil 4 passes through two connecting line connection senses
Answer coil life tape deck 1.Induction coil life-span tape deck 1 is provided with serial ports touch-screen 2, potentiometer 3 is regulation current potential
Device R1.
In fig. 2, Hall current sensor CHK-Y4 samples primary current, obtains voltage signal DCIP, whole by waveform
Output is Vf voltage signals after shape circuit, and Vf voltage signals pass through single chip machine controlling circuit, and single-chip microcomputer determines whether effectively to add
Thermal signal, if effective heating signal, count value adds 1, writes memory module, send serial ports touch-screen to show, if count value exceedes
Induction coil life-span preset value, then lightening LED lamp prompted.
In figure 3, Hall current sensor CHK-Y4 is mounted in isolating transformer T1 primary sides, samples primary current ,+
15V, -15V leading-out terminal connection external power source+15V, -15V, the square wave that Hall current sensor output is rated value ± 4V, electricity
Pressure value size is proportional to the size of sampled current value.When power supply does not heat, transformer T1 primary currents are 0, and Hall sensor is defeated
It is 0 to go out voltage, and less than the reference voltage Vref of U1A negative input ends, Vf is low level always, and U2 captures frequency as 0；It is normal to add
When hot, primary current is symmetrical square wave, Hall current sensor DCIP leading-out terminals output symmetrical square wave voltage signal DCIP, is passed through

Only, no current flows through in coil, and Hall sensor output is that zero, U1 output signals Vf is low level always, and MCU captures frequency
For 0, once heating is completed, numeration plus 1, and is write in outer memory module U3, U2 and serial ports touch panel communication, updates screen
Show numerical value；If record numerical value keeps OFF state not less than preset value, holding U2 PC13 pin low levels, LED, if
Record numerical value exceedes preset value, then the pin of U2 the 4th output high level, lightening LED lamp, prompts user to change induction coil.To power supply
When carrying out small-power debugging, when Hall sensor output voltage values are less than the reference voltage Vref of U1A negative input ends, Vf is always
Low level, the frequency that MCU is captured are 0, are determined as invalid heating, without counting.After changing of coils, pass through serial ports touch-screen
The heating times stored in U3 are emptied, start to count the heating times of new coil.Such as change variety classes, different operating modes
Coil, serial ports touch-screen can be passed through and write new life expectancy value.
In Fig. 4, Ip is isolating transformer T1 primary current waveforms, and DCIP is Hall sensor output voltage waveforms, V+
