When input power under normal circumstances, be approximately equal to 1V as preferred optocoupler conducting voltage, thus arrange Vloin- Vloout voltage peaks are more than 1V, and Vhi in-Vhiout voltage peaks are less than 1V, now green indicating lamp work, and redness is indicated Lamp and buzzer (active buzzer BUZZER or passive buzzer BUZZER) do not work.

Resistance Rn2, resistance Rn3, resistance Rn4 are parallel with one another, and whether it is one group of detection input power less than predetermined input The circuit of power, the Vloout pressure drop waveforms of its input Vloin and outfan after resistance Rn2, resistance Rn3, resistance Rn4 are in parallel Consistent with input current waveform, with the change of input current, Vloin-Vloout voltage waveforms follow change, work as Vloin- Triggering alarm opens buzzer warning and display lamp abnormal work is indicated when Vloout voltage peaks are less than about 1V.

Resistance Rn6, resistance Rn7, resistance Rn8 are parallel with one another, and whether it is one group of detection input power more than predetermined input The circuit of power bracket, the Vhiout pressure drops of its input Vhiin and outfan after resistance Rn6, resistance Rn7, resistance Rn8 are in parallel Waveform is consistent with input current waveform, and with the change of input current, Vhi in-Vhiout voltage waveforms follow change, when Triggering alarm opens buzzer warning and display lamp abnormal work is indicated when Vhiin-Vhiout voltage peaks are greater than about 1V.

When optocoupler is not turned on, then Vloo is that R11 is equal to (VDC/ (R12+R11)) * R12 with R12 partial pressures, and same Vhio is R21 is equal to (VDC/ (R22+R21)) * R22 with R22 partial pressures；Two comparison voltages point that the feet of comparator U4 the 2nd and the 6th foot are introduced Wei not (VDC/ (R14+R13)) * R14, (VDC/ (R23+R24)) * R24；By the setting of resistance value so that (VDC/ (R12+ R11))*R12>(VDC/(R14+R13))*R14；(VDC/(R22+R21))*R22>(VDC/(R23+R24))*R24.The present invention In, the reference voltage at the foot of comparator the 2nd and the 6th foot is set to by 5.4V by the selection of resistance, Vloo when optocoupler is not turned on Voltage is set to 6V at place and Vhio.

Resistance R16, resistance R17, electric capacity C11, electric capacity C12 and intervalometer U5 constitute one group of delay circuit, same electricity Resistance R26, resistance R27, electric capacity C21, another group of delay circuit of electric capacity C22 and intervalometer U6, this delay circuit function is (containing anti- To function) it is, when input voltage is high, to be output as ground state；When input voltage is low, high-impedance state is output as；When input by Low when switching to high, output can keep the T=1.1*RC times to be then grounded for high-impedance state；So when input is every t (t<T) the time For it is low when, output can remain continuously high-impedance state.

When Vcontrol is low level, audion Q2, Q4 are not turned on, then Q5 conductings, active buzzer BUZZER not works Make, green indicating lamp work, while driving timing device U8 Enable Pins do not work for low, audion Q3 is not turned on, red led Do not work；When Vcontrol is high level, Vcontrol direct drive audion Q2, Q4 conductings, then Q5 is not turned on, active honeybee Ring device BUZZER starts working, and green indicating lamp does not work, while driving timing device U8 Enable Pins are driven for high output of starting working Galvanic electricity pressure drives audion Q3, red led flicker work.

Active buzzer BUZZER or passive buzzer BUZZER can be used with selection circuit in the present invention, only need to be according to tool Body situation selects the circuit matched with it.
