Specific embodiment
Embodiment one
Screen cannot be put out for a long time after electricity in order to solve to pull out in the prior art, while being pulled out and being powered on long-time again after electricity and cannot open
The technical issues of machine, the embodiment of the present invention one provide a kind of processing method pulled out and quickly put out screen after electricity, referring to figure 2. shown in,
Specifically includes the following steps:
Step S21, when small household electrical appliance plug-in, i.e., when 220V is powered on, show that small household electrical appliance is energized, then enter just
Beginningization program.
Step 22, system initialization.
Initialization is exactly that some variables are arranged to default value, and some controls are arranged to default shape by such as register etc.
State, while entering preparation state, it is identical as step S23, S24, S27 and S28, it is the prior art.
S23, major cycle.
Major cycle is mainly used for calling some functions, and exits main circulating program in some special cases.Here it provides
A kind of specific implementation code of major cycle:
S24, general program setting.
General program setting mainly includes some specific parameters, such as the sampling time etc..
S25, zero cross signal detection.
It is detected by the zero cross signal to zero cross detection circuit, so that realization quickly puts out screen after pulling out electricity, is stood after energization
Self-test and normal function is executed, when zero cross signal is normal, successively execute step S26-S28, when no zero cross signal, successively executed
Step S29-S31.
Zero cross detection circuit is as shown in Figure 3 comprising zero cross detection circuit includes alternating current, auxiliary DC power supply, first point
The control terminal of volt circuit, the second bleeder circuit, third bleeder circuit and electronic switch, electronic switch passes through the first bleeder circuit
It is connected to alternating current, the input terminal of electronic switch is connected to auxiliary DC power supply VCC (such as 5V), electronics by the second bleeder circuit
The input terminal of switch also passes through third bleeder circuit output suspect signal, the output end ground connection of electronic switch.
As an implementation, the second bleeder circuit and third bleeder circuit are respectively resistance R5 and resistance R6, and first
Bleeder circuit includes resistance R1, resistance R2, resistance R3 and resistance R4, and one end of resistance R1 is connected to alternating current, and the other end successively passes through
By the control terminal for being connected to electronic switch after resistance R2 and resistance R3；One end of resistance R4 is connected to resistance R3 and electronic switch
Between control terminal, other end ground connection.Meanwhile the first filter capacitor C1 and the second filter capacitor C2 is set, wherein the first filtered electrical
One end of appearance is connected between resistance R3 and the control terminal of electronic switch, and one end of other end ground connection, the second filter capacitor C2 connects
It is connected between resistance R6 and the input terminal of electronic switch.Electronic switch is NPN triode Q1, the base stage of NPN triode Q1, current collection
Pole and emitter respectively correspond control terminal, input terminal and the output end of electronic switch.
When energized, i.e., alternating current side is connected, then when 220V positive half cycle passes through zero cross detection circuit, NPN triode Q1 is led
Logical, the suspect signal of output is low level；When 220V passes through zero cross detection circuit, NPN triode Q1 cut-off, the letter to be checked of output
It number is high level, that is to say, that be plugged into alternating current and realize that the suspect signal of output is alternate high level and low electricity when being powered
Flat, the frequency of the suspect signal of output is identical as mains frequency (50Hz or 60Hz), by taking 50Hz as an example, when low and high level is alternate
Between be 10ms.
When pulling out electricity, i.e. alternating current side is disconnected, then NPN triode Q1 is ended, and the suspect signal of output is continuously high level,
One threshold value, such as 30ms are set for its duration, if high level lasting time reaches 30ms, product is in and pulls out electric shape
State.
Successively, it is possible to determine that whether small household electrical appliance is pulled out electricity, if output suspect signal be high level, and continue when
Between more than 30ms, then be judged to being pulled out electricity, the suspect signal of output is alternate high level and low level, then is judged to being powered.
To determine whether zero cross signal is normal by the suspect signal of output, if suspect signal is that high and low level is pre- with third
If the time is persistently alternately present, then zero cross signal is normal, if suspect signal is continuously high level, no zero cross signal.
S26, zero cross signal are normal.
When zero cross signal is normal, i.e., suspect signal is that high and low level is (true according to mains frequency with third preset time
When being persistently alternately present calmly), step S27 is executed.
S27, power-on self-test.
When indicator light all light, alarm (buzzer) rings a sound, then self-test is completed, and is immediately performed step S28.
S28, normal function.
Oneself is completed, and normal functional state is immediately entered, and so-called normal functional state, i.e. key can be operated, and is shown
Display screen is lit, i.e., small household electrical appliance can enter working condition at any time.
S29, without zero cross signal.
If suspect signal is continuously high level and when high level lasting time reaches 30ms, it is identified as no zero passage letter
Number, execute step S30.
S30, etc. the second preset time buffering.
Second preset time is setting value, such as 1s or 2s, the buffer time are mainly used for filtering, to prevent from shaking.
After buffer time, it is immediately performed step S31.
Screen is put out in S31, shutdown.
At this point, circuit board still has electricity, but no matter whether circuit board has electricity, the detection module detected to zero cross signal
(such as single-chip microcontroller) controls display screen (or/and indicator light) and extinguishes, meanwhile, key cannot be operated, and flag bit is reset.
If S32, after zero cross signal normal (zero cross signal normal continuous regular hour) is converted to no zero cross signal
Why booting (limits in this way, is to exclude from unused situation, from being not used, then zero cross signal, circuit board are also impossible to
Have electricity), since the electricity on circuit board nowhere consumes, then the electricity on the circuit board always exists, at this point, if booting, shows
Presupposed information, such as presupposed information are E4, then show that alternating current has been unplugged, but circuit board still has electricity.
S33, no matter S31 or S32, as long as small household electrical appliance is constantly in shutdown and puts out screen state without zero cross signal.
I.e. S32 display screen puts out screen after showing presupposed information immediately.
Detection module persistently detects the zero cross signal of zero cross detection circuit, determines whether small household electrical appliance is energized
(step S34) is continued to test when out of power always (step S35), until powering on, when energized (step S36), is then powered on
Self-test simultaneously enters normal functional state.
The embodiment of the present invention one is by detecting the zero cross signal that zero cross detection circuit exports, so that after pulling out electricity, this
When put out at once screen shutdown, expression pulled out electricity, when powering on self-test and enter normal functional state, improve user experience.
