Description

The invention relates to a motion detector with integrated alarm device according to the preamble of claim 1 and to an alarm system with at least two motion detectors. The invention can be used in a motion detector to be mounted inside / outside a building.

From the DE19540299C2 an infrared detector with two connected to an evaluation circuit detectors is known, which are assigned to different to be monitored spatial angle ranges. If an object enters the monitored solid angle range, the change in the irradiance is detected by means of the evaluation circuit and a signal is passed on to an actuating device which switches a light source or an alarm signal.

From the DE10 2004 012 605A1 an interior light with interior monitoring device for vehicles is known, which has at least one connectable via an actuating device with the power supply of the vehicle illuminant for illuminating the vehicle interior and at least one IR motion detector for monitoring the vehicle interior. The IR motion detector has an alarm signal output connected to an alarmer and a control signal input connected to a vehicle interior interlocking device, via which the indoor monitoring device interrupts a monitor state in which the output of an alarm signal to the alarm signal output is enabled and an idle state in which the output the alarm signal is disabled, is switchable. The interior monitoring device is at least in idle state in control connection with the actuating device for the lighting means. In the idle state, the detection range of the IR motion detector is reduced in comparison to the monitoring state such that the IR motion detector can be used for non-contact optical actuation of the luminous means.

Prior art motion detectors with integrated alarm device for mounting inside or outside a building are flush or surface mounted motion detectors in passive infrared or radar technology. In addition to the usual main task of a motion detector, namely the automatic and motion-dependent switching on a lighting, there are also motion detectors with an integrated alarm device and motion detector for connection to separate alarm systems. Disadvantages of this prior art result from the fact that, depending on the application, a motion detector with different properties is to be used:

A) Motion detectors for lighting purposes:

• High detection sensitivity,
• - high detection range,
• - device with power supply connection for flush or surface mounting,
• - Probability of false trigger (= false triggering) is high.

B) Motion detector for alarm purposes:

• - lower detection sensitivity
• - lower detection range
• - Appliance with mains connection and / or battery supply / buffering, rather on-wall or "stand-alone" design usual,
• - Probability of false trigger is low.

The invention has for its object to provide an improved motion detector with integrated alarm device.

Furthermore, the invention has for its object to provide an alarm system with at least two motion detectors.

This object is achieved according to the invention in terms of the motion detector in conjunction with the Markmalen the preamble by the features specified in the characterizing part of claim 1.

The object is achieved with respect to the alarm system with at least two motion detectors by the features specified in claim 8.

The advantages achieved by the invention are, in particular, that a very cost-effective "mini alarm system" is created, their operation is very simple, since an "arming" of a single motion detector when leaving the building is sufficient. With little additional effort, an alarm system with two, three or more motion detectors can be created.

Further advantages will be apparent from the following description.

Advantageous embodiments of the invention are characterized in the subclaims.

The invention will be explained below with reference to the embodiments illustrated in the drawings. Show it:

1 a basic version of a motion detector with integrated alarm device,

2 . 3 two different ways of switching a motion detector for lighting and alarm purposes,

4 . 5 . 6 three different options for the alarm device,

7 . 8th . 9 three different options for forwarding an alarm,

10 a triggered "chain reaction" of alarm striking motion detectors.

In 1 is a basic version of a motion detector with integrated alarm device shown. It is a motion detector 1 shown, which by means of a switch 2 can be set in two different operating modes:

A) Mode I:

• • motion detector is activated for the lighting,
• • a high detection sensitivity is set,
• • a high detection range is set,
• • The probability of false triggering (false triggering) is high.

B) Mode II:

• • Motion detector is activated for alarm purposes (alarm mode, "arming")
• • a low detection sensitivity is set,
• • a low detection range is set,
• • the probability of false trigger is low.

As is apparent from the above explanations, the combined use of the motion detector for lighting purposes and for alarm purposes requires an adaptation of the device parameters to the different tasks. When activating the motion detector for alarm purposes, it is important to increase the number of required triggers per time interval for triggering the switching function. This is necessary to avoid malfunction and accidental high-security alarm triggering in "Alarm Mode".

Activation of the switch 2 takes place by means of a switching device 3 with a first deadtime member. By means of this first deadtime element is taken into account that after arming "leaving the monitored building within a predetermined period of time still must be possible without alarm triggering.

When a movement in mode I is detected, the motion detector is acted upon 1 a lighting 4 as is well known.

Upon detection of movement in mode II is via a drive circuit 5 with a second dead-time member an alarm device 6 (and possibly also the lighting 4 ) is activated. By means of this second deadtime element is taken into account that in a "armed" motion detector 1 It must be possible to enter the building within a predefined period of time without triggering the alarm in order to switch a "armed" motion detector into operating mode I.

In the 2 . 3 Two different ways of switching a motion detector for lighting and alarm purposes are shown. The under 1 explained admission of the switch 2 , ie switching between the two modes I and II is carried out according to embodiment according to 2 by an example manual switching device 7 (Including the above-mentioned first deadtime member). According to embodiment according to 3 In the case of a motion detector installed outdoors, the changeover switch is acted on 2 , ie switching between the two operating modes I and II, by a brightness sensor 8th with downstream evaluation unit 9 , This allows the motion detector 1 Automatically "armed" after prolonged darkness. The return to the mode I is z. B. depending on the signal of the brightness sensor 8th ,

• • Gemäß 4 beaufschlagt die Ansteuerschaltung 5 die Beleuchtung 4, wodurch die Beleuchtung 4 mit vorgegebener Frequenz (beispielsweise im Sekundentakt) zyklisch ein- und ausgeschaltet wird.
• • Gemäß 5 beaufschlagt die Ansteuerschaltung 5 einen vorzugsweise im Gehäuse des Bewegungsmelders 1 selbst integrierten Signaltonerzeuger („Buzzer”) 10, wodurch ein lauter und durchdringender Signalton vorgegebener Frequenz erzeugt wird.
• • Gemäß 6 beaufschlagt die Ansteuerschaltung 5 sowohl die Beleuchtung 4 als auch den Signaltonerzeuger 10 in vorstehend erwähnter Art und Weise.

In the 4 . 5 . 6 Three different options for the alarm device are shown:

• • According to 4 acts on the drive circuit 5 the lighting 4 , causing the lighting 4 is cyclically switched on and off at a predetermined frequency (for example, every second).
• • According to 5 acts on the drive circuit 5 a preferably in the housing of the motion detector 1 even integrated beep generator ("Buzzer") 10 , whereby a loud and penetrating beep of predetermined frequency is generated.
• • According to 6 acts on the drive circuit 5 both the lighting 4 as well as the beep generator 10 in the manner mentioned above.

In all cases it is expediently ensured with a (preferably electronic) interlock that a switching off of the alarm by actuation of the manual changeover device is suppressed for a predetermined period of time.

• • Gemäß 7 ist ein weiterer im Gebäude oder außerhalb des Gebäudes montierter Bewegungsmelder 11 vorgesehen, welcher über seinen Helligkeitssensor 12 mit nachgeschalteter Auswerteeinheit 13 die vom Bewegungsmelder 1 mit vorgegebener Frequenz zyklisch ein- und ausgeschaltete Beleuchtung 4 detektiert, hieraus den Alarmzustand ableitet und infolgedessen eine ihm zugeordnete Beleuchtung 14 ebenfalls mit einer vorgegebener Frequenz ein- und ausgeschaltet, um hierdurch einen Alarmzustand zu signalisieren.
• • Gemäß 8 ist ein weiterer im Gebäude oder außerhalb des Gebäudes montierter Bewegungsmelder 15 vorgesehen, welcher über ein Mikrofon 16 mit nachgeschalteter Auswerteeinheit 17 den vom Signaltonerzeuger 10 des Bewegungsmelders 1 produzierten Signalton detektiert, hieraus den Alarmzustand ableitet und infolgedessen einen in seinem Gehäuse integrierten Signaltonerzeuger 18 aktiviert, wodurch dieser seinerseits einen lauten und durchdringenden Signalton vorgegebener Frequenz erzeugt, um hierdurch einen Alarmzustand zu signalisieren.
• • Gemäß 9 ist ein weiterer im Gebäude oder außerhalb des Gebäudes montierter Bewegungsmelder 19 vorgesehen, welcher über seinen Helligkeitssensor 12 mit nachgeschalteter Auswerteeinheit 13 die vom Bewegungsmelder 1 mit vorgegebener Frequenz zyklisch ein- und ausgeschaltete Beleuchtung 4 detektiert, hieraus den Alarmzustand ableitet und infolgedessen eine ihm zugeordnete Beleuchtung 14 ebenfalls mit einer vorgegebener Frequenz zyklisch ein- und ausgeschaltet, um hierdurch einen Alarmzustand zu signalisieren, und/oder welcher über ein Mikrofon 16 mit nachgeschalteter Auswerteeinheit 17 den vom Signaltonerzeuger 10 des Bewegungsmelders 1 produzierten Signalton detektiert, hieraus den Alarmzustand ableitet und infolgedessen einen in seinem Gehäuse integrierten Signaltonerzeuger 18 aktiviert, wodurch dieser seinerseits einen lauten und durchdringenden Signalton vorgegebener Frequenz erzeugt, um hierdurch einen Alarmzustand zu signalisieren.

In 7 . 8th . 9 In order to create an alarm system, three different possibilities for forwarding an alarm are shown:

• • According to 7 is another motion detector mounted inside or outside the building 11 provided, which via its brightness sensor 12 with downstream evaluation unit 13 the motion detector 1 cyclically switched on and off with predetermined frequency lighting 4 detected, from this the alarm state derives and consequently an associated lighting 14 also turned on and off at a predetermined frequency to thereby signal an alarm condition.
• • According to 8th is another motion detector mounted inside or outside the building 15 provided, which via a microphone 16 with downstream evaluation unit 17 from the beep generator 10 of the motion detector 1 detected signal tone, thus deriving the alarm state and consequently a built-in beech sound generator in its housing 18 activated, which in turn generates a loud and penetrating beep of predetermined frequency, thereby signaling an alarm condition.
• • According to 9 is another motion detector mounted inside or outside the building 19 provided, which via its brightness sensor 12 with downstream evaluation unit 13 the motion detector 1 cyclically switched on and off with predetermined frequency lighting 4 detected, from this the alarm state derives and consequently an associated lighting 14 also cyclically switched on and off with a predetermined frequency to thereby signal an alarm condition, and / or which via a microphone 16 with downstream evaluation unit 17 from the beep generator 10 of the motion detector 1 detected signal tone, thus deriving the alarm state and consequently a built-in beech sound generator in its housing 18 activated, which in turn generates a loud and penetrating beep of predetermined frequency, thereby signaling an alarm condition.

• • ein weiterer Bewegungsmelder erkennt die mit vorgegebener Frequenz zyklisch ein- und ausgeschaltete Beleuchtung 4 und aktiviert daraufhin einen in seinem Gehäuse integrierten Signaltonerzeuger, wodurch dieser seinerseits einen lauten und durchdringenden Signalton vorgegebener Frequenz erzeugt, um hierdurch einen Alarmzustand zu signalisieren oder
• • ein weiterer Bewegungsmelder erkennt den vom Signaltonerzeuger 10 des Bewegungsmelders 1 produzierten Signalton und beginnt daraufhin, eine ihm zugeordnete Beleuchtung ebenfalls mit einer vorgegebener Frequenz ein- und ausgeschaltet, um hierdurch einen Alarmzustand zu signalisieren.

Of course, with regard to the alarm system, other alternative embodiments can be realized, for example

• • another motion detector detects the lighting cyclically switched on and off at the specified frequency 4 and then activates an integrated in its housing beep generator, which in turn generates a loud and penetrating beep of predetermined frequency, thereby signaling an alarm condition or
• • another motion detector detects the signal from the beep generator 10 of the motion detector 1 produced signal and then begins, a lighting assigned to him also with a predetermined frequency turned on and off, thereby signaling an alarm condition.

• • Bewegungsmelder 19 ein Lichtsignal und/oder einen Signalton des Bewegungsmelders 1 detektiert, hieraus einen Alarmzustand ableitet und daraufhin seinerseits ein Lichtsignal und/oder einen Signalton abgibt, um hierdurch einen Alarmzustand zu signalisieren,
• • Bewegungsmelder 20 ein Lichtsignal und/oder einen Signalton des Bewegungsmelders 19 detektiert, hieraus einen Alarmzustand ableitet und daraufhin seinerseits ein Lichtsignal und/oder einen Signalton abgibt, um hierdurch einen Alarmzustand zu signalisieren,
• • Bewegungsmelder 21 ein Lichtsignal und/oder einen Signalton des Bewegungsmelders 20 detektiert, hieraus einen Alarmzustand ableitet und daraufhin seinerseits ein Lichtsignal und/oder einen Signalton abgibt, um hierdurch einen Alarmzustand zu signalisieren.

In 10 is a triggered "chain reaction" of alarm striking motion detectors of an alarm system shown. There are four motion detectors 1 . 19 . 20 . 21 to recognize, where

• • Motion detector 19 a light signal and / or a signal tone of the motion detector 1 detects, then derives an alarm state and then in turn emits a light signal and / or a signal tone, thereby signaling an alarm condition,
• • Motion detector 20 a light signal and / or a signal tone of the motion detector 19 detects, then derives an alarm state and then in turn emits a light signal and / or a signal tone, thereby signaling an alarm condition,
• • Motion detector 21 a light signal and / or a signal tone of the motion detector 20 detects, thereby deriving an alarm state and then in turn emits a light signal and / or a signal tone, thereby signaling an alarm condition.

As explained above, results in an alarm forwarding the alarm system, wherein motion detector 1 acts as "master" and the other motion detectors 19 . 20 . 21 serve as a "slave". Several alarm-striking motion detectors, combined with many loud beeps and several asynchronously cyclically switching on and off lights inside and outside a building, alert neighbors to the alarm and reliably detonate burglars.

Advantageous (in all embodiments of the alarm system according to the 7 - 9 ) have to go through the first motion detector 1 triggered another motion detector 11 . 15 . 19 . 20 . 21 not yourself in "alarm mode". The detection of the motion detector 1 triggered alarm on the other motion detectors 19 . 20 . 21 is done in a simple manner by the frequency evaluation of the lighting on and off, since this is not a naturally occurring lighting condition and / or by detecting / evaluating the signal.

The reset of a motion detector in alarm condition (deactivation) takes place z. B. by a switching device whose switching function is not immediately recognizable.
