Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, do not limit the present invention.
As shown in Figure 1, the embodiment of the present invention provides a kind of intelligent alarm method, comprising:
S11, every default assay intervals, receives the detection signal of self-detector;
S12, reports to the police when the instruction result of described detection signal meets alert if;
S13, adjusts described alert if according to the average alarm interval in preset period of time, reports to the police according to the described alert if after adjustment to make the new detection signal received.
The intelligent alarm method that the embodiment of the present invention provides, every default assay intervals, receive the detection signal of self-detector, report to the police when the instruction result of detection signal meets alert if, and, can also according to the average alarm interval adjustment alert if in preset period of time, report to the police according to the described alert if after adjustment to make the new detection signal received, thus can report to the police with optimal alert frequency, avoid the electric energy that frequent false alarm causes and consume excessively and bothering user.
It should be noted that, in Smart Home applied environment, need the position of carrying out alarm detection to have many places, such as courtyard front door, doorway, room, garage etc., can need the position of reporting to the police that detecting device is set respectively at these.Detecting device can utilize infrared acquisition principle, carries out periodic monitor and reports, namely carry out one-time detection every default assay intervals and testing result is passed to server the environment of these positions and flow of personnel situation.In step s 11, server can receive a series of detection signals that detecting device sends, this detection signal can indicate corresponding detecting device and whether target be detected, such as, if do not detect, echo signal can be high level, if detect, echo signal can be low level, specifically can carry out arranging and changing according to agreement.
In order to ensure accuracy of detection, detecting device is general higher to the detection frequency of surrounding environment, such as, will carry out one-time detection to surrounding environment every 10 seconds to 60 seconds and report testing result to server.The electric energy caused in order to avoid frequent false alarm consumes excessively and bothering user, in step s 12, suitable alert if can be set according to detection time, detection site and concrete testing result, report to the police when the detection signal that server receives meets this alert if.Such as, in one embodiment of the invention, suppose that infrared probe high level represents that surveyed area is unmanned, low level represents that surveyed area has people.Radio infrared module detected every 10 seconds state of once popping one's head in, and reports at once, arrive continuous 10 times afterwards and low level detected, then can think there is people at this region continuously active, now again report meaningless, so no longer report after low level being detected for the first time.Low level detected, or be again changed to low level after high level being detected, then think there is new activity, again report for 11st time.
In another embodiment of the present invention, alert if can also be set to: when described detection signal indicates first and target detected, report to the police; After reporting to the police first, when the described detection signal instruction of continuous k detects target, just again report to the police, wherein, k be greater than 2 integer.Like this, if detecting device detects and time interval of reporting is certain, so the value size of k just decides the minimum interval of once reporting to the police with another warning.The different working time section of the detecting device of diverse location, detecting device needs how to arrange alarm interval can by realizing the adjustment of k value.
Optionally, k value this how to adjust could adapt to current detection and report to the police needs, can by carrying out analysis to draw to the alert data of the nearest a period of time of just having pass by.
Such as, in step s 13, adjust described alert if according to the average alarm interval in preset period of time can comprise the steps:
Determine that the average σ-K width interval in described preset period of time equals, described preset period of time is divided by the alarm times in described preset period of time;
When k described default assay intervals is doubly greater than first threshold with the ratio of described average alarm interval, increase the value of k in described alert if;
When k described default assay intervals is doubly less than Second Threshold with the ratio of described average alarm interval, reduce the value of k in described alert if.
Illustrate, in one embodiment of the invention, if, household is successively from unit goes back home the quitting time in the afternoon.Before this, because whom family do not have, the possibility of false alarm is less, therefore by alarm interval set of time is: detection signal instruction detects target (namely k equals 3) to 3 times continuously, then once report to the police.If within every 10 seconds, carry out a target detection according to detecting device to calculate, if having exception in sensing range, so alarm is minimum just once reported to the police every 30 seconds.If when first kinsfolk returns, alarm just sent according to each 30 seconds originally and once reports to the police, and due to first kinsfolk frequent activities at home, alarm just may send and even more report to the police for more than 10 time within short a few minutes.
If after 10 minutes, second kinsfolk return, he would not cause alarm to report to the police so frequently.Because now, alert if is adaptive to be adjusted, and detailed process is as follows:
Determine that the average σ-K width interval in nearest 10 minutes in the past equals over nearest 10 divided by the alarm times in nearest 10 minutes of described past.Calculate according to having during this period to report to the police for 20 times, so, the average σ-K width interval in nearest 10 minutes of past just equals 10 minutes/20 times, namely 0.5 minute, 30 seconds.Like this, k described default assay intervals is doubly 3 × 10 seconds/30 seconds=1 with the ratio of described average alarm interval.That is, this alarm, in allowed band, farthest carries out having reported to the police, and in fact reports to the police without the need to so frequent, therefore, needs to adjust alert if, reduces alert frequency.
In the present embodiment, suppose that first threshold is 0.5, then this ratio 1 is greater than first threshold 0.5, so need to increase k value, such as k is become 36 from 3, so now alert if just becomes: detection signal instruction detects target continuous 36 times, just once reports to the police.Still once calculate to detect for 10 seconds, when second kinsfolk is to family, 360 seconds (6 minutes) are wanted interval in twice warning at least, therefore, avoid the electric energy that frequent false alarm causes and consume excessively and bothering user.
As a same reason, when k described default assay intervals is doubly less than Second Threshold with the ratio of described average alarm interval, can also reduce the value of k in described alert if, reason is similar to the above embodiments, repeats no more herein.
Optionally, first threshold can set according to the different of application scenarios from the concrete numerical value of Second Threshold, and accordingly, the strategy increasing k or reduction k also can change according to demand, and embodiments of the invention are not construed as limiting this.Such as, in one embodiment of the invention, when k described default assay intervals is doubly greater than 0.7 with the ratio of described average alarm interval, can by double for k value; When k described default assay intervals is doubly less than 0.1 with the ratio of described average alarm interval, then thinks and k can be made the activity do not continued in surveyed area to recover default value, such as, make k value equal 3.
Accordingly, as shown in Figure 2, embodiments of the invention also provide a kind of intelligent alarm device, comprising:
Receiving element 21, for every default assay intervals, receives the detection signal of self-detector;
Alarm unit 22, for reporting to the police when the instruction result of described detection signal meets alert if;
Adjustment unit 23, for adjusting described alert if according to the average alarm interval in preset period of time, reports to the police according to the alert if after adjustment to make the new detection signal received.
The intelligent alarm device that the embodiment of the present invention provides, receiving element 21 can receive every default assay intervals the detection signal of self-detector, and when the instruction result of detection signal meets alert if, alarm unit 22 can carry out reporting to the police with reminding user.And, adjustment unit 23 can also according to the average alarm interval adjustment alert if in preset period of time, report to the police according to the described alert if after adjustment to make the new detection signal received, thus can report to the police with optimal alert frequency, avoid the electric energy that frequent false alarm causes and consume excessively and bothering user.
