Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 2 is a schematic flow chart of a false triggering prevention method according to an embodiment of the present invention.
An embodiment of the present invention provides a method for preventing false triggering in motion detection, including:
and S10, acquiring the PIR amplitude.
The method for acquiring the PIR amplitude comprises the following steps: and acquiring PIR amplitude acquired by the infrared pyroelectric sensor.
It should be noted that the execution end of the false triggering prevention method for motion detection is preferably a false triggering prevention device for motion detection, and the false triggering prevention device collects the PIR amplitude in real time through the infrared pyroelectric sensor, draws the PIR waveform through the PIR amplitude, and further judges whether a moving object exists through the PIR amplitude.
S20, judging whether at least one PIR amplitude value is larger than any amplitude value in a preset first amplitude value interval and at least one PIR amplitude value is smaller than any amplitude value in a preset second amplitude value interval in a preset time interval.
It should be noted that, since the waveform of the human walking is a bidirectional pulse, a preset first amplitude interval and a preset second amplitude interval are set. In this embodiment, the PIR waveform is obtained by collecting the PIR amplitude in real time, and it can be understood that one of the first amplitude interval and the second amplitude interval is a positive interval and the other one is a negative interval, so as to determine whether the PIR amplitude within the preset time interval can form the bidirectional pulse. The trigger device may be set by the factory when the trigger device is triggered by mistake, or may be set according to a large number of experiments, which is not limited herein.
And S30, if yes, triggering the motion detection system to detect the motion of the moving object.
Specifically, when the PIR amplitude within the preset time interval forms a bidirectional pulse, it indicates that a moving object passes through, so as to perform motion detection. It should be noted that the moving object includes: human, animal, and the like.
S30', if not, the motion detection system is not triggered to perform motion detection.
Specifically, when the PIR amplitude within the preset time interval forms a bidirectional pulse, it indicates that no moving object passes through, and no motion detection is performed.
In summary, by determining whether at least one PIR amplitude is greater than any amplitude in the preset first amplitude interval and at least one PIR amplitude is less than any amplitude in the preset second amplitude interval within the preset time interval, if yes, the motion detection system is triggered to perform motion detection on the moving object, and if not, the motion detection system is not triggered to perform motion detection. Therefore, by setting the amplitude interval, the motion detection is performed only when the amplitude within the preset time interval is larger than any amplitude within the preset first amplitude interval and smaller than any amplitude within the preset second amplitude interval, so that the condition that the PIR motion detection system is frequently triggered by mistake is reduced, and the detection result of the PIR motion detection system is more accurate.
In one implementation, the first amplitude interval and the second amplitude interval are symmetric intervals.
Specifically, the first amplitude interval and the second amplitude interval are symmetrical intervals, so that the obtained waveform is closer to a symmetrical waveform, the waveform with smaller amplitude is filtered, and the probability of false touch can be reduced.
Referring to fig. 3-4, in an implementation manner, the determining whether at least one PIR amplitude is greater than any amplitude in a preset first amplitude interval and at least one PIR amplitude is smaller than any amplitude in a preset second amplitude interval exists in a preset time interval, and the step S20 specifically includes:
s200, judging whether at least one PIR amplitude value is larger than a preset third amplitude value threshold value and at least one PIR amplitude value is smaller than a preset sixth amplitude value threshold value in a preset time interval.
S201, judging whether at least one PIR amplitude value is larger than a preset fifth amplitude value threshold value and at least one PIR amplitude value is smaller than a preset fourth amplitude value threshold value in a preset time interval. The maximum value of the first amplitude interval is the fifth amplitude threshold, the minimum value of the first amplitude interval is the third amplitude threshold, the maximum value of the second amplitude interval is the fourth amplitude threshold, the minimum value of the first amplitude interval is the sixth amplitude threshold, the third amplitude threshold and the fourth amplitude threshold are opposite numbers, and the fifth amplitude threshold and the sixth amplitude threshold are opposite numbers.
It should be noted that, if it is only determined that at least the PIR amplitude is greater than the seventh amplitude threshold and at least one PIR amplitude is smaller than the eighth amplitude threshold, the false triggering condition is easily increased, and therefore, setting an amplitude range can reduce the false triggering condition and also reduce the false triggering condition.
In this embodiment, referring to graph X, the third amplitude threshold is + thethreshold _ low, the fourth amplitude threshold is-Therehold _ low, the fifth amplitude threshold is + Therehold, and the fifth amplitude threshold is Therehold. It can be understood that the third amplitude threshold, the fourth amplitude threshold, the fifth amplitude threshold, and the fifth amplitude threshold may be set when the false trigger-proof trigger device leaves a factory, or may be set according to actual needs, which is not limited herein.
Referring to fig. 5, in an implementation, after the obtaining the PIR waveform according to the PIR amplitude value, the method further includes:
when the PIR waveform only has a one-way peak, judging whether the PIR waveform in a preset time interval meets a preset detection system triggering condition; the detection system comprises a PIR waveform detection system, a PIR waveform detection system and a PIR waveform detection system, wherein the PIR amplitude of sampling points in the PIR waveform exceeds a preset amplitude threshold value in a slow-moving state, and the number of the sampling points is greater than the preset number of samples; in this embodiment, the preset number of samples is set to 5, and may also be other numbers, which is not limited herein. The amplitude threshold in the crawl state is set according to a number of experiments.
If yes, the mobile detection system is triggered to carry out mobile detection on the moving object.
If not, the mobile detection system is not triggered to carry out mobile detection.
Specifically, since the amplitude of the PIR waveform is small when a person is walking slowly, the motion detection system cannot be triggered. Therefore, when the PIR waveform only has a unidirectional peak, the PIR amplitude value of more than five sampling points exceeds the preset amplitude threshold value in the slow walking state, the situation that a pedestrian is in the slow walking state at present is indicated, and the mobile detection system is triggered at the moment, so that the situation of missing report is reduced.
