Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail:
Referring to Fig. 1, the present embodiment provides a kind of intelligent quilt of light-operated lamp dynamic induction method, and the method comprises:
Step 101 is arranged pyroelectric infrared sensor array;
Above-mentioned pyroelectric infrared sensor array is made up of the pyroelectric infrared sensor of multiple same model, and array format circularizes, and in pyroelectric infrared sensor array between each transducer spacing less, make their induction region basically identical.
Step 102 is installed Fresnel Lenses on pyroelectric infrared sensor;
Above-mentioned installation Fresnel Lenses adopts the Fresnel Lenses of same model, a Fresnel Lenses is installed on the each pyroelectric infrared sensor in described pyroelectric infrared sensor array, is converted to pulse signal after mobile human body signal is responded to by pyroelectric infrared sensor.
Step 103 adds up the output signal of each pyroelectric infrared sensor in pyroelectric infrared sensor array;
In above-mentioned pyroelectric infrared sensor array, each transducer all produces identical output signal according to the target conditions in induction zone, these output signals cumulative is exactly the enhancing signal about target, and as the output signal of described pyroelectric infrared sensor array.
Step 104 is amplified described cumulative signal;
Personnel leave, in induction zone, move, in induction zone, are still in the Ji induction zone, clear zone of Fresnel Lenses and are still in the dark space situation of Fresnel Lenses from induction zone, and amplifying signal is respectively referring to Fig. 2 a, Fig. 2 b, Fig. 2 c and Fig. 2 d.
Step 105 is differentiated to the signal after amplifying;
Personnel leave, in induction zone, move, in induction zone, are still in the Ji induction zone, clear zone of Fresnel Lenses and are still in the dark space situation of Fresnel Lenses from induction zone, and differential signal is respectively referring to Fig. 3 a, Fig. 3 b, Fig. 3 c and Fig. 3 d.
The signal after described differentiating is carried out rectification processing by step 106, and export the signal after rectification;
Signal rectification processing after above-mentioned differentiating comprises: directly rectification and first anti-phase rectification again.
Directly rectification: personnel leave, move in induction zone, are still in the clear zone of Fresnel Lenses in induction zone, are still in induction zone in the dark space situation of Fresnel Lenses from induction zone, and rectified signal is respectively referring to Fig. 4 a, Fig. 4 b, Fig. 4 c and Fig. 4 d.
Anti-phase rear rectification: personnel leave, move in induction zone, are still in the clear zone of Fresnel Lenses in induction zone, are still in induction zone in the dark space situation of Fresnel Lenses from induction zone, and anti-phase rectified signal is respectively referring to Fig. 5 a, Fig. 5 b, Fig. 5 c and Fig. 5 d.
The signal of exporting after rectification comprises direct rectified signal and anti-phase rectified signal.
Step 107 has driftlessness to enter induction zone according to the signal judgement of exporting after rectification.
The signal of exporting after above-mentioned rectification is pulse signal, judges and in induction zone, has or not personnel according to pulse amplitude and width.
In induction zone nobody time, the signal that above-mentioned steps 106 is carried out direct rectification and the first anti-phase output of rectification again to the signal after differentiating is close to 0; When personnel leave from induction zone, the amplitude of exporting pulse after the signal rectification after step 106 is differentiated diminishes gradually, pulsewidth is less; While having people to move in induction zone, the amplitude of exporting pulse after the signal rectification after step 106 is differentiated is large, pulsewidth is less; While having people to be still in the clear zone of Fresnel Lenses in induction zone, step 106 is exported after to the signal rectification after differentiating and in pulse, is occurred the pulse that a rising edge rising amplitude is large, pulsewidth is very large; While having people to be still in the dark space of Fresnel Lenses in induction zone, the amplitude of exporting pulse after the signal rectification after step 106 is differentiated is large, pulsewidth is less, and keeps output signal to approach 0 state after an in the end pulse.Therefore, when step 106 output signal is close to 0 or when output amplitude diminishes gradually, pulsewidth is less pulse, shown in induction zone or be about to unmannedly, in the time that step 106 output signal is other form, showing has people in induction zone.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
