Embodiment
For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that embodiment of the present invention is done to describe in detail further below:
Referring to Fig. 1, present embodiment provides a kind of intelligent quilt of light-operated light fixture dynamic induction method, and this method comprises:
Above-mentioned pyroelectric infrared sensor array is made up of the pyroelectric infrared sensor of a plurality of same model, and array format circularizes, and in the pyroelectric infrared sensor array between each transducer spacing less, make their induction region basically identical.
Above-mentioned installation Fresnel Lenses adopts the Fresnel Lenses of same model; A Fresnel Lenses is installed on each pyroelectric infrared sensor in said pyroelectric infrared sensor array, is converted into pulse signal after making the mobile human body signal by the pyroelectric infrared sensor induction.
Each transducer all produces identical output signal according to the target conditions in the induction zone in the above-mentioned pyroelectric infrared sensor array; These adding up of signal of output are exactly the enhancing signal about target, and as the output signal of said pyroelectric infrared sensor array.
Personnel leave from induction zone, in induction zone, move, in induction zone, are still in the clear zone of Fresnel Lenses and in induction zone, are still under the dark space situation of Fresnel Lenses, and amplifying signal is respectively referring to Fig. 2 a, Fig. 2 b, Fig. 2 c and Fig. 2 d.
Signal after the step 105 pair amplification is differentiated;
Personnel leave from induction zone, in induction zone, move, in induction zone, are still in the clear zone of Fresnel Lenses and in induction zone, are still under the dark space situation of Fresnel Lenses, and differential signal is respectively referring to Fig. 3 a, Fig. 3 b, Fig. 3 c and Fig. 3 d.
The signal of step 106 after with said differentiating carries out rectification to be handled, and the signal after the output rectification;
Signal rectification after above-mentioned the differentiating is handled and is comprised: directly rectification and first anti-phase rectification again.
Directly rectification: personnel leave from induction zone, in induction zone, move, in induction zone, are still in the clear zone of Fresnel Lenses, in induction zone, are still under the dark space situation of Fresnel Lenses, and rectified signal is respectively referring to Fig. 4 a, Fig. 4 b, Fig. 4 c and Fig. 4 d.
Rectification after the anti-phase: personnel leave from induction zone, in induction zone, move, in induction zone, are still in the clear zone of Fresnel Lenses, in induction zone, are still under the dark space situation of Fresnel Lenses, and the 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 the rectification comprises direct rectified signal and anti-phase rectified signal.
The signal that step 107 is exported after according to rectification is judged has driftlessness to get into induction zone.
The signal of exporting after the above-mentioned rectification is a pulse signal, according to having or not personnel in pulse amplitude and the width judgement induction zone.
In the induction zone nobody the time, the signal after 106 pairs of above-mentioned steps are differentiated carry out direct rectification and first anti-phase again the signal of rectification output approach 0; When personnel left from induction zone, the amplitude of exporting pulse behind the signal rectification after step 106 is differentiated diminished gradually, pulsewidth is less; When having the people to move in the induction zone, the amplitude of output pulse is big behind the signal rectification after step 106 is differentiated, pulsewidth is less; When having the people to be still in the clear zone of Fresnel Lenses in the induction zone, the pulse that a rising edge rising amplitude is big, pulsewidth is very big appears in the output pulse behind the signal rectification after step 106 pair is differentiated; When having the people to be still in the dark space of Fresnel Lenses in the induction zone, the amplitude of output pulse is big behind the signal rectification after step 106 is differentiated, pulsewidth is less, and keeps the output signal near 0 state after pulse in the end.Therefore, when step 106 output signal approaches 0 or during output amplitude diminishes gradually, pulsewidth is less pulse, shown in the induction zone or be about to unmannedly that when step 106 output signal was other form, showing had the people in the induction zone.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
