Embodiment one

Fig. 1 is indoor anti-intrusion detection device structural representation in embodiment one of the present utility model, as Shown in Fig. 1, indoor anti-intrusion in the present embodiment detection device include first detector the 1, second detector 2, Control device 3, alarm device 4 and alarm set 5.Wherein, the first detector 1 is pre-in detecting chamber If human activity signal in region, such as, shown in Fig. 2, indoor anti-intrusion detection device is located at window frame internal upper part Or balcony door outer upper, window limit or the human activity signal on balcony doorway are arrived in the first detector 1 detection. Human activity signal outside second detector 2 is before detecting window or on balcony, its investigative range is visited with first Survey the non-overlapping covering of investigative range of device 1, so that it is guaranteed that user (owner) must from indoor activity to outdoor First detected by the first detector 1, the most just detected by the second detector 2.

First detector 1 and the second detector 2 are all connected with the input controlling device 3, control device 3 Outfan be connected with alarm device 4, alarm set 5 respectively.Control device 3 according to human activity signal's Identify that principle produces different reactions to the first detector 1 with the signal that the second detector 2 inputs and exports.When When first detector 1 detects human activity signal, control device 3 output trigger signal to alarm set 5, Alarm set 5 is made to enter the duty of preset duration.When the second detector 2 detects human activity signal Time, control device 3 and judge that alarm set 5 is the most in running order, the most then control device 3 and make to carry Device 5 of waking up goes successively to the duty of preset duration, if it is not, then control device 3 output to trigger signal extremely Alarm device 4, makes 4 alarm devices enter duty.The principle that is easily recognized of above-mentioned human activity signal can With reference to shown in Fig. 3.

Above-mentioned alarm set 5 can be various ways, and such as alarm set 5 is audio alert device, can lead to Crossing to send points out audio frequency to remind user, and alarm set 5 can also is that light alarm set, passes through User is reminded by flash of light.The most only illustrate as a example by audio alert device, but can not limit with this Make protection domain of the present utility model.

Concrete, with reference to shown in Fig. 3, preset duration is 10 seconds, and the first detector 1 measures physical activity letter After number, control device 3 output triggering signal, to alarm set 5, makes the work that alarm set 5 enters 10 seconds State, such as alarm set 5 first send the first prompting audio frequency, remind user to be in the exterior space, no Transfixion to be continued (dormancy of such as lying down) more than 10 seconds, makes alarm device 4 by control device 3 simultaneously Warning function be suppressed (being equal to withdraw a garrison).If hereafter user keeps interrupted activity in the external world, second When detector 2 detects human activity signal again, due to alarm set in working order, therefore only can cause Controlling device 3 and persistently export the duty triggering signal maintenance alarm set 5, in other words, second visits Surveying device 2 output signal makes indoor anti-intrusion detection device locate all the time during the activity of window or balcony user In exiting warning state on duty.It is also preferred that the left alarm set is triggered after work 7,8 seconds, can be because user exist Do not keep interrupted activity on window or balcony or returned to indoor, making the second detector 2 during this period Inside do not detect human activity signal and go to maintain the work of alarm set 5, and send the second prompting audio frequency, Inform that user indoor anti-intrusion detection device will proceed to find out at any time the warning state on duty of the outsider.

Assume that user stops action in the external world, and keep the time of resting state more than 10 seconds, so work as user Again during activity, the second detector 2 will detect human activity signal, and now alarm set 5 is not the most in work Making state, control device 3 by output triggering signal to alarm device 4, alarm device 4 receives after triggering signal Enter duty, perform alarm action.

The operation logic of circuit shown in Fig. 6 is described underneath with positive level logical signal, explains control with this The operation principle of device 3.In figure 6, signal VD1 refers in particular to microwave Doppler detector 23 in spy every time After measuring human activity signal, after its internal circuit calculation process, externally export the square wave of about 1 second about 3V Signal；In like manner, VD2 refers in particular to the first Infrared Detectors 21 after detecting human activity signal every time, through it The square-wave signal of about 1 second about 3V is externally exported after internal circuit calculation process；VD3 refers in particular to the second infrared spy Survey device 22, after detecting human activity signal, externally exports about 1 after its internal circuit calculation process every time The square-wave signal of second about 3V；VD4 refers in particular to curtain-type Infrared Detectors 11 and is detecting physical activity every time After signal, after its internal circuit calculation process, externally export the square-wave signal of about 1 second about 3V.As one Kind of optional embodiment, resistance R1, R5, R8 as current-limiting resistance, desirable 220K Ω, electric capacity C1, C2 all can be selected for ceramic condenser.

With reference to circuit shown in Fig. 6, first Infrared Detectors the 21, second Infrared Detectors 22, microwave in Fig. 6 Doppler detector 23, curtain-type Infrared Detectors 11, the running voltage of each inverter module, PNP are brilliant Body pipe emitter stage external voltage is V_DD.Optionally, V_DDFor 5V_。

Circuit work process shown in Fig. 6 is as follows:

If all nobody approaches window or enters balcony for indoor, outdoor, first detector the 1, second detector 2 is all Do not detect human activity signal, now VD1=VD2=VD3=VD4=0 (no-voltage), phase inverter list The output of unit U2, U5, U7 and U9 is all low level, and A, B, N, B each point current potential is all that electronegative potential (connects It is bordering on zero), inverter module U3 exports high level, thus switching transistor T1, T2 are all without switched on. Alarm device 4 and alarm set 5 there is no to power up and would not enter work.

Hereafter indoor before still nobody approaches window or enter balcony, the first detector 1 (curtain-type Infrared Detectors 11) output VD4 is 0.But the second detector 2 detects human activity signal, i.e. VD1 and VD2 Or VD3 successively becomes high level signal, and (as above-mentioned, VD1, VD2, VD3, VD4 are about 1 second here High level square-wave signal).

If first there being VD1 (microwave Doppler detector) that the high level square-wave signal of 1 second occurs, although Inverter module U2 can export high level immediately, but owing to the outfan of inverter module U5 is always low electricity Flat, through the clamping action of diode D4, A point can not be formed high potential by diode D1 charging, anti-phase Device unit U3 still exports high level, and PNP transistor T1 is still in cut-off state, and alarm device 4 is not Work.Owing to B point remains electronegative potential, thus N point is also electronegative potential, and NPN transistor T2 also will not Conducting, alarm set 5 also will not work.As can be seen here, the second detector 2 only has microwave Doppler to visit Surveying device 23 and detect human activity signal, indoor anti-intrusion detection device will not cause alarm.This can be avoided The outside wet clothes of dry in the sun, the wrong report caused of rocking etc. of leaves are misrepresented deliberately.

If also having VD2 or VD3 that high level side occurs in 1 second after high level square-wave signal occurs in VD1 Ripple (i.e. Infrared Detectors also has detection output), owing to the output of inverter module U5 transfers high level, P to Point becomes high potential (inverter module U8 exports high level always), and A point just can be rapidly by diode D1 Charging causes inverter module U3 to transfer low level at high potential making PNP transistor T1 turn on, alarm device 4 obtain work close to powering up of VDD (audible alarm, take pictures or launch wireless encoding signal call connection System etc.), and operating time have about 5 seconds (because resistance R3, electric capacity C1 constitute RC circuit time Between constant be 10 seconds, then) or longer (the second detector 2 persistently exports high level, alarm Device 4 will persistently alert).Otherwise, if first there being the high level side of (Infrared Detectors) VD2 or VD3 Ripple occurs, has again the high level square wave of (microwave Doppler detector) VD1 to occur, then phase inverter in 1 second Unit U3 can make PNP transistor T1 turn on along with the appearance of high level directly overturns for low level, drives Alarm device 4 works.

And if not having VD2, VD3 that high level square wave occurs after high level square wave occurs in VD1, no matter then The high level square wave of VD1 the most how long, and A point is electronegative potential all the time, and PNP transistor T1 does not turns on all the time Alarm device 4 is made to work.

Equally, if only VD2 or VD3 occurs that high level square wave does not has VD1 high level square wave occur, I.e. only having Infrared Detectors to be triggered, the high level of inverter module U5 output is due to by two poles as seen from Figure 5 Pipe D4 isolates, and causes P point, A point to remain within electronegative potential and makes inverter module U3 export high level, PNP transistor T1 can not turn on and make alarm device 4 work.This is equally avoided only infrared detector The wrong report that (the most interim thermal current, sunlight) etc. cause that is triggered is misrepresented deliberately.

The process (being exactly to control device 3 to trigger the process of alarm) more than making alarm device 4 work is the most multiple Miscellaneous be because that doppler detector the 23, first Infrared Detectors the 21, second Infrared Detectors 22 is constituted the Two detectors 2 have played the effect of dual technology detector herein, the most only meet doppler detector and infrared Detector is almost concurrently detected human activity signal just can carry out warning and treat.Such being applied in combination can Significantly reduce only bring by the infrared a kind of Detection Techniques of human body heat-releasing wrong report, misrepresent deliberately.Certainly, existing above Describing, the second detector can also use three mirror detectors or only with Infrared Detectors (single mirror detection), uses Single mirror detects this simplified way and can be used for the most external window etc..

If before indoor first have owner to approach window or enter balcony, as seen from Figure 6, because high electricity occurs in VD4 Square wave causes inverter module U7 output to transfer high level to, the RC loop that electric capacity C2, resistance R9 are formed The charging obtaining diode D7 makes inverter module U8 output low level at least 10 seconds.Due to diode The clamper of D6, P point would be at electronegative potential 10 seconds, would be impossible to during this trigger inverter module U3 Output low level makes the conducting of PNP transistor T1 cause alarm device 4 to work, and is namely equivalent to make room Interior anti-intrusion detection device exits warning state on duty 10 seconds.Inverter module U9 output simultaneously transfers height to Level also has 10 seconds, so that NPN transistor T2 conducting causes alarm set to work 10 seconds, and example As sent certain prompting sound with prompting user (owner) in outdoor, the most totally stationary motionless, otherwise The own activity occurred after more than 10 seconds will cause warning.

If hereafter user left window in 10 seconds or returns indoor, in circuit, the high potential of B point can not get Continued support and resistance R9 to electric capacity C1 electric discharge more than half after make phase inverter U8 export into high level, anti-phase Device U9 output low level makes NPN transistor T2 terminate conducting, and alarm set 5 will quit work.Simultaneously by Returning to high potential in P point, the second detector 2 is in again the state on duty that can cause alarm at any time.

If user continues at window or balcony after 10 seconds, so long as not totally stationary motionless, as above-mentioned, by Investigative range in the first detector 1 and the second detector 2 is mutually isolated does not intersects, and therefore owner is from indoor Must be to first result in VD4 high level square wave occurs to outdoor activity, make phase inverter U8 be output in low level About 10 seconds, when owner continues to stretch forward outside window or enters balcony, could be detected by the second detector 2, As long as hereafter there being continual human activity signal (high level square wave occurs in VD2 or VD3), B just can be made The high potential of point obtains continuous print and maintains, so that alarm set 5 continuous firing, is specifically shown in Fig. 5.Owner's Although continuation activity causes the second detector 2 to output again VD1, VD2 or VD3 of high level, but B point The low level that during maintaining high potential, inverter module U8 exports, through the clamper of diode D6, can make P point Become is electronegative potential always, even if thus inverter module U2, U5 all export high level and be also impossible to make anti-phase Device unit U3 tilts out low level and makes PNP transistor T1 turn on.Certainly, defeated at inverter module U5 When going out for low level, or due to the clamping action of diode D8 during inverter module U9 output low level, N point does not haves high level and goes to maintain that (in Fig. 5, resistance R7 is 10K Ω, resistance R9 to the charging of B point It is far smaller than resistance R9 for 10M Ω, resistance R7.) but as long as VD2 or VD3 of high level occurs (i.e. As long as there being the Infrared Detectors in the second detector 2 to detect the physical activity of user) inverter module U5 is just Can transfer to high level through diode D5, resistance R6, resistance R7 electric capacity C2 is persistently charged (in Fig. 5 electricity Resistance R6 is 220K Ω, is far smaller than resistance R9 equally).

Owner exceedes such as the 8th second in outdoor quiescent time in fact, and alarm set 5 will be at 10 seconds precedents As the 8th second sends the second information, user indoor anti-intrusion detection device is reminded to enter shape on duty of reporting to the police State, if user's just continuation activity after 10 seconds, first will be detected by the second detector 2, and A point will go out Existing high level causes the conducting of PNP transistor T1 to cause alarm device 4 to enter duty, thus causes announcement Alert.Regardless of whether user (owner) activity outside is how long, as long as returning indoor more than 10 seconds, due to C2 Losing charging to support, B point will turn into electronegative potential, and U8 output transfers high level to, just it has been observed that system is entered again Enter state on duty, as long as the second detector has output signal (VD1, VD2 or VD3 occur) with regard to energy T1 conducting is caused to cause alarm device 4 to work at any time.

The use sight occurred for many people, described above can have equifinality.

Device 3 is controlled it becomes clear from the above description that built by Digital Logical Circuits shown in Fig. 6, just can be to the The human activity signal that one detector 1 and the second detector 2 detect independently processes, and decision is to cause Alarm or entrance etc. are to be reminded, so can be achieved with owner user and do not find window and balcony in time in period The outsider of upper appearance, can persistently exit warning shape on duty in the active stage chien shih detection system that owner occurs again State, regardless of whether owner's activity on window or balcony is how long, anti-in leaving window or balcony of short duration time rear chamber Intrusion detection apparatus can enter again state on duty of reporting to the police.

In sum, this utility model utilizes the commercialized technology of noncontact detection physical activity, passes through curtain In the detectable indoor predeterminable area such as formula Infrared Detectors, first detector of human activity signal, detects master Before whether people enters balcony or approach window, by obtaining outdoor physical activity towards the second outdoor detector Signal, and by the first detector input control device together with the output signal of the second detector, control device According to not being owner occurs being exactly that the judgment principle of the outsider judges, during being in alarm set work The human activity signal that interior (in 10 seconds) are detected by the second detector does not the most do alarming processing, as long as The human activity signal that in not during alarm set works, all elder generations are detected by the second detector is carried out without exception Alarm, and by alarm set constantly point out user come window or enter continue after balcony the most static not Dynamic, just allow indoor anti-intrusion detection device move back before making user (owner) come window or after its entrance balcony temporarily Go out state on duty of reporting to the police, until owner window, balcony activity disappeared (without human activity signal) after, Make indoor anti-intrusion detection device proceed to report to the police on duty the most as early as possible, just can find in time to occur in afterwards window, The outsider of balcony also alerts it, thus realizes being not required to owner's manipulation and deploy troops on garrison duty or withdraw a garrison, and just can whole day independently transport OK, persistently carry out taking precautions against monitoring to window, balcony.

Each technical characteristic of embodiment described above can combine arbitrarily, for making description succinct, the most right The all possible combination of each technical characteristic in above-described embodiment is all described, but, if these skills There is not contradiction in the combination of art feature, is all considered to be the scope that this specification is recorded.
