Be used to the 1ms that delays time, the step of time=time+1;
Be used to judge whether time equals the step of dyn;
If time is not equal to dyn, then return the described 1ms that delays time that is used to, the step of time=time+1;
If dyn equals time, then be used to close the step of oil sprayer;
Be used for the 1ms time-delay, the step of time=time+1;
Be used to judge whether time equals 8 step;
If time is not equal to 8, then return the described 1ms of being used for time-delay, the step of time=time+1;
If time equals 8, then be used for the step of Num=Num+1;
Be used to judge whether Num equals 1000 step;
If Num is not equal to 1000, then return the described oil sprayer that is used to open, the step of the counter time=0 during main control chip (U1) operation; Again carry out dynamic monitoring;
If Num equals 1000, then return described main control chip (U1) and judge the whether step of conducting of first switch (S1);
Described static monitoring comprises:
Be used for oil sprayer and open, the step of counter time=0;
Be used for time-delay in 1 minute, the step of time=time+1;
Be used to judge whether sta equals the step of time;
If sta is not equal to time, return described time-delay in 1 minute, the step of time=time+1 of being used for;
If sta equals time, be used for the step that oil sprayer cuts out;
Return the described whether step of conducting of first switch (S1) of judging.
