The circuit course of work shown in fig. 6 is as follows:
If it is indoor and outdoor all nobody approach window or enter balcony, the first detector 1, the second detector 2 all do not detect
To human activity signal, VD1=VD2=VD3=VD4=0 (no-voltage) at this time, the output of inverter module U2, U5, U7 and U9
It is all low level, A, B, N, B each point current potential are all low potential (close to zero), and inverter module U3 exports high level, thus opens
Closing transistor T1, T2 will not all be switched on.Alarm device 4 and alarm set 5, which there is no power-up, would not enter work.
Hereafter indoor still nobody approach before window or enter balcony, the first detector 1 (curtain-type infrared detector 11)
Exporting VD4 is 0.But the second detector 2 detects human activity signal, i.e. VD1 and VD2 or VD3 successively at high level signal (such as
Above-mentioned, VD1, VD2, VD3, VD4 are about 1 second high level square-wave signals here).
If it is the high level square-wave signal for first thering is VD1 (microwave Doppler detector) to occur 1 second, although inverter module
U2 can export high level immediately, but since the output end of inverter module U5 is always low level, by the clamper of diode D4
Effect, A point cannot charge by diode D1 and form high potential, and inverter module U3 still exports high level, PNP transistor T1 according to
Old to be in off state, alarm device 4 does not work.Since B point is still low potential, thus N point is also low potential, NPN crystal
Pipe T2 will not be connected, and alarm set 5 will not work.It can be seen that only having microwave Doppler detector in the second detector 2
23 when detecting human activity signal, and indoor anti-intrusion detection system will not cause alarm.This can be to avoid the tide of outside sunning
Wrong report caused by shaking of wet wash, leaf etc. is misrepresented deliberately.
If also thering is VD2 or VD3 (the i.e. infrared spy of high level square wave occur in 1 second after high level square-wave signal occurs in VD1
Surveying device also has detection to export), since the output of inverter module U5 switchs to high level, P point becomes high potential (inverter module U8
High level is exported always), A point can cause inverter module U3 to switch to low level by diode D1 charging in high potential rapidly to be made
PNP transistor T1 conducting, alarm device 4 obtain close to VDD power-up and work (audible alarm, take pictures or emit wirelessly compile
Code signal calling connection etc.), and operating time has about 5 seconds (because the time for the RC circuit that resistance R3, capacitor C1 are constituted is normal
Number is 10 seconds, then) or longer (the second detector 2 persistently exports high level, and alarm device 4 will continue to accuse
It is alert).Conversely, having (microwave Doppler detection in 1 second again if first there is the high level square wave of (infrared detector) VD2 or VD3 to occur
Device) VD1 high level square wave occur, then inverter module U3 also can with the appearance of high level directly overturn be low level and make
PNP transistor T1 conducting, drives alarm device 4 to work.
And if there is no VD2, VD3 high level square wave occur after high level square wave occurs in VD1, no matter the height electricity of VD1
Square wave continue how long, A point is low potential always, and PNP transistor T1 is not turned on always makes alarm device 4 work.
Equally, if high level square wave, which occur, in only VD2 or VD3 high level square wave occurs without VD1, i.e., only infrared
Line detector is triggered, and the high level of inverter module U5 output causes P point, A due to being isolated by diode D4 as seen from Figure 5
Point remains within low potential and inverter module U3 is made to export high level, and PNP transistor T1, which cannot be connected, makes 4 work of alarm device
Make.This can equally be triggered to avoid only infrared detector reports mistake by mistake caused by (such as interim thermal current, sunlight) etc.
Report.
Make above alarm device 4 work process (be exactly control device 3 triggering alarm process) it is complex be because
The second detector 2 that doppler detector 23, the first infrared detector 21, the second infrared detector 22 are constituted plays here
The effect of dual technology detector only meets doppler detector and infrared detector almost while detecting human activity signal
It just can be carried out alarm to treat.Such be applied in combination can significantly reduce only with a kind of infrared Detection Techniques bring of human body heat-releasing
It reports by mistake, misrepresent deliberately.Certainly, it has been described above, the second detector can also be using three heads detector or only (single with infrared detector
Mirror detection), detecting this simplified way using single mirror can be used for directly not external window etc..
If before interior first has owner to approach window or entering balcony, as seen from Figure 6, because high level square wave guide occurs in VD4
Inverter module U7 output is caused to switch to high level, the charging that the circuit RC that capacitor C2, resistance R9 are formed obtains diode D7 makes instead
Phase device unit U8 is exported low level at least 10 seconds.Due to the clamper of diode D6, P point would be at low potential 10 seconds, this
Period, which would be impossible to triggering inverter module U3 output low level, to be connected PNP transistor T1 and alarm device 4 is caused to work,
It is just comparable to that indoor anti-intrusion detection system is made to exit alarm state on duty 10 seconds.Inverter module U9 output simultaneously switchs to
High level also has 10 seconds, works 10 seconds so that NPN transistor T2 conducting be made to cause alarm set, such as issue certain prompt
The sound, should not be totally stationary motionless to remind user (owner) in outdoor, otherwise, more than 10 seconds after the own activity that occurs will
Alarm police can be caused.
Hereafter if user is in leaving window or retracting interior in 10 seconds, the high potential of B point cannot continue branch in circuit
It holds and makes phase inverter U8 output at high level after resistance R9 is more than half to capacitor C1 electric discharge, phase inverter U9 output low level makes NPN
Transistor T2 terminates to be connected, and alarm set 5 will stop working.Simultaneously because P point is restored to high potential, the second detector 2 is located again
In the state on duty that can cause alarm at any time.
It is such as above-mentioned only if it were not for totally stationary motionless if continued after user 10 seconds in window or balcony, it visits due to first
The investigative range of survey device 1 and the second detector 2 is mutually isolated not to intersect, therefore owner must be first from interior to outdoor activity
Cause VD4 high level square wave occur, phase inverter U8 made to be output in low level about 10 seconds, when owner continue to stretch forward outside window or into
Enter balcony, could be detected by the second detector 2, (height occur in VD2 or VD3 as long as hereafter there is continual human activity signal
Level square wave), the high potential of B point can be enabled to obtain continuous maintenance, so that alarm set 5 be made to continue working, be specifically shown in Fig. 5.,
Although the continuation activity of owner leads to the second detector 2 and outputs VD1, VD2 or VD3 of high level, but B point maintains high potential
The low level of period inverter module U8 output passes through the clamper of diode D6, and P point can be made to become low potential always, thus even if
Inverter module U2, U5 export high level and are also impossible to that inverter module U3 is made to tilt out low level and enable PNP transistor T1
Conducting.Certainly, due to diode when inverter module U5 output is low level or when inverter module U9 exports low level
The clamping action of D8, N point are not in that high level goes to maintain the charging to B point (resistance R7 is 10K Ω in Fig. 5, and resistance R9 is
10M Ω, resistance R7 are far smaller than resistance R9.But as long as) there is the VD2 of high level or VD3 (as long as there is the second detector 2
In infrared detector detect the physical activity of user) inverter module U5 will switch to high level through diode D5, resistance
R6, resistance R7 persistently charge (resistance R6 is 220K Ω in Fig. 5, equally far smaller than resistance R9) to capacitor C2.
Owner is more than such as 8 second second in outdoor quiescent time in fact, and alarm set 5 will be such as the 8th second in 10 seconds precedents
Clock issues the second prompt information, reminds anti-intrusion detection system in user room that will enter state on duty of alarming, if user is 10
Just continuation activity after second, will be detected first by the second detector 2, and high level, which will occur, in A point causes PNP transistor T1 to be connected
Cause alarm device 4 and enter working condition, to cause alarm.Regardless of user (owner) outside activity how long, as long as retracting
Supported that B point will turn into low potential, and U8 output switchs to high level, as preceding since capacitor C2 loses charging more than 10 seconds in interior
State, indoor anti-intrusion detection system enters alarm state on duty again, as long as the second detector have output signal (VD1, VD2 or
VD3 occurs) T1 can be caused to be connected at any time and cause the work of alarm device 4.
It is described above to have equifinality for the scene that uses of more people appearance.
It becomes clear from the above description that constructing control device 3 by Digital Logical Circuits shown in fig. 6, can be detected to first
The human activity signal that device 1 and the second detector 2 detect carries out from main process task, and decision is to cause alarm or mention into waiting
It wakes up, so can be achieved with owner user and do not find the outsider occurred on window and balcony in time in period, and can go out in owner
So that detection system is persistently exited alarm state on duty during existing activity, regardless of owner on window or balcony activity how long,
State on duty of alarming can be entered again by leaving anti-intrusion detection system in window or the of short duration time rear chamber of balcony.
In conclusion the present invention passes through curtain-type infrared acquisition using the commercialized technology of non-contact detection physical activity
Whether the first detector of human activity signal in the detectable indoor predeterminable area such as device enters balcony or approaches to detect owner
Before window, detected by obtaining outdoor human activity signal towards the second outdoor detector, and by the first detector and second
Input control device, control device foundation are not the judgment principle progress that owner's appearance is exactly the outsider to the output signal of device together
Judgement, to the human activity signal that is detected (in such as 10 seconds) by the second detector is not without exception during the alarm set work
Alarming processing is done, to all human activity signals one that all elder generations are not detected by the second detector during alarm set works
Rule is alerted, and should not be persistently stationary after constantly prompting by alarm set user to come window or entrance balcony,
Make user (owner) come before window or its enter balcony after just allow indoor anti-intrusion detection system temporarily to exit alarm state on duty,
Until owner window, balcony activity disappeared (no human activity signal) after, and make as early as possible indoor anti-intrusion detection system turn
Enter to alarm on duty, can find in time after appear in window, balcony the outsider and alert it, thus realize be not required to owner behaviour
Control deployment is withdrawn a garrison, and energy whole day autonomous operation persistently carries out prevention monitoring to window, balcony.
