The other end is grounded.
Specifically, the discrimination circuit in the present embodiment carries out DC bus-bar voltage using the circuit that resistance, capacitor are constituted
Be delayed sample detecting, and not only circuit structure is simple, but also low in cost.Wherein it should be noted that the capacitance of the second capacitor C2
Greater than the capacitance of first capacitor C1.Specifically, the second capacitor C2 is big capacitance capacitor, for example, the concretely μ F order of magnitude even F
The order of magnitude.Since the second capacitor C2 capacitance is larger, its electric discharge phenomena is significant after alternating current power-off, compared to DC bus
Voltage, the outage detection signal decline that discrimination circuit is exported is more slow, also, by the way that resistance and capacitor is rationally arranged

Often operation and monitoring.
In view of user using flash switch when touching by duration it is shorter, generally no longer than 5s, therefore, for flash
Switch carry out switch motion when appearance of short duration power-off, voltage value will drop to the model not less than a certain predetermined voltage threshold
In enclosing.Conversely, for powering off for a long time caused by grid cut-off, the voltage value of the output of discrimination circuit will be substantially less than should
Voltage threshold, or even close to zero.As a result, after detecting circut breaking using detection circuit, if discrimination circuit output is disconnected
The voltage swing of power detection signal is lower than the voltage threshold, then is determined as the long-time power-off of power grid；If discrimination circuit exports
Outage detection signal voltage swing be not less than the voltage threshold, then be determined as flash switch of short duration power-off.
Shown in Figure 5, the embodiment of the present application discloses another flash switch detection circuit；Including rectifying and wave-filtering electricity
Road, detection circuit, DC-DC converter, control circuit and discrimination circuit；
The input terminal of current rectifying and wave filtering circuit is used to switch by flash and connect with AC power source, the output of current rectifying and wave filtering circuit
End be all connected with the input terminal of detection circuit and the input terminal of DC-DC converter, for the alternating current of input carry out rectification with
Filtering is to export DC bus-bar voltage；The output end of detection circuit and the first AD input terminal of control circuit connect, for straight
Stream busbar voltage is sampled to detect the switch motion of flash switch, is generated and is exported flash and detects signal to control circuit；
The output end of DC-DC converter and the feeder ear of control circuit connect, for powering to control circuit；Control circuit is used for basis
Flash detection signal judges the switch state of flash switch；The input terminal of discrimination circuit and the output end of DC-DC converter connect,
The output end of discrimination circuit and the 2nd AD input terminal of control circuit connect, for DC bus-bar voltage carry out delay sampling with
The circut breaking for detecting alternating current generates and exports outage detection signal to control circuit, distinguishes alternating current by control circuit

Specifically, the present embodiment is also equipped with discrimination circuit, by prolonging to the supply voltage that DC-DC converter exports
When sample detecting come identify power grid long-time power-off, and will delay sampled signal, that is, outage detection signal export to control circuit
The 2nd AD input terminal, be AD converted by control circuit and analyzed with voltage swing, so that control circuit is by the long-time of power grid
Power-off with because flash switch progress switch motion caused by flash phenomenon distinguish.
It is easily understood that the supply voltage of DC-DC converter output is the pressure stabilizing via voltage regulator circuit inside converter
The burning voltage exported afterwards, compared with DC bus-bar voltage, fall off rate of the supply voltage after alternating current power-off is more slow.
Therefore, when flash, which switchs, to be carried out switch motion and lead to alternating current flash, inspection is powered off to the delay sampled value of supply voltage
The size for surveying signal will be not less than some voltage threshold；And when grid cut-off has cut off the power supply of entire circuit, to confession
Delay sampled value, that is, outage detection signal size of piezoelectric voltage will be significantly lower than the voltage threshold, thus can be realized to because
Flash switch carries out the differentiation of alternating current flash phenomenon and power grid long-time circut breaking caused by switch motion.
Shown in Figure 6, the embodiment of the present application discloses a kind of circuit structure diagram of the discrimination circuit in Fig. 5；The area
Parallel circuit includes 3rd resistor R3, the 4th resistance R4 and the second capacitor C2；One end of the 3rd resistor R3 and the DC-DC become
The output end of parallel operation connects, the other end respectively with one end of the 4th resistance R4, one end of the second capacitor C2 and described
2nd AD input terminal of control circuit connects；The other end of the other end of the 4th resistance R4 and the second capacitor C2 connect
Ground.
Similarly, the discrimination circuit in the present embodiment carries out DC bus-bar voltage using the circuit that resistance, capacitor are constituted
Be delayed sample detecting, and not only circuit structure is simple, but also low in cost.It is easily understood that the outage detection signal of output is
The both end voltage of 4th resistance R4, those skilled in the art can be arranged according to the actual application and rationally 3rd resistor R3 and
The resistance value of 4th resistance R4, to adjust the discharge time of the second capacitor C2.Particularly, 3rd resistor R3 and the 4th resistance R4 can be with
It is variable resistance, to facilitate adjusting resistance value.
In addition, the capacitance of the second capacitor C2 is greater than the capacitance of first capacitor C1, i.e. the second capacitor C2 is big capacitance capacitor, example
Such as, concretely the μ F order of magnitude even the F order of magnitude.Since the second capacitor C2 capacitance is larger, it is put after alternating current power-off
Electrical phenomena is significant, and compared to DC bus-bar voltage, the outage detection signal decline that discrimination circuit is exported is more slow, also,
Its fall off rate is adjusted by the way that resistance and capacitor's capacity is rationally arranged.
After exchanging electrically disconnected, DC bus-bar voltage rapid decrease, after dropping to a certain degree, under supply voltage just starts
Drop, when supply voltage is reduced to certain value, control circuit stops working, and the voltage at the second both ends capacitor C2 is begun to decline.If
Alternating current turn-off time is longer, and wireless module or microprocessor in control circuit etc. will restart, when alternating current re-powers
Afterwards, supply voltage is gradually increased to normal value, and wireless module or microprocessor in control circuit etc. start to work normally, control
Circuit processed continues with AD conversion function and carries out voltage analysis to outage detection signal.Therefore, for being opened because of flash
The alternating current flash of pass movement and generation, because alternating current power-off time is shorter, so circuit restores electricity rapidly after flash
When, the electricity of the second capacitor C2 is not let go also completely, i.e. for the second capacitor C2 still in discharge condition, voltage is higher；For electricity
Net powers off for a long time, because alternating current power-off time is longer, the electricity of the second capacitor C2 almost discharges completely, in circuit weight
The electricity of the second capacitor C2 has been zeroed when newly powering on, and voltage is lower, and preparation is started to charge.
As a result, after detecting circut breaking using detection circuit, if the outage detection signal that discrimination circuit is exported
Voltage swing is lower than preset voltage threshold, then is determined as the long-time power-off of power grid；If the outage detection of discrimination circuit output
