    Motion detector and light system with motion detector
    FIELD OF THE INVENTION
    The present invention relates to a motion detector. Furthermore, the present invention relates to a lighting system with such a motion detector and a method for controlling such a motion detector.
    TECHNICAL BACKGROUND
    Motion detectors are typically permanently installed devices that are designed to detect persons, animals or other objects within a sensitive area and based on a detection, for example, turn on a light or trigger an alarm. For example, a motion detector can be installed on a building and connected to a luminaire or an arrangement of luminaires. If the motion detector is activated and, for example, a person approaches the building, the motion detector detects the movement of the person and switches on the lights for a fixed period of time. If at the end of this time period no person moves in the sensitive area, the lights will be displayed again. Otherwise, the lights remain on for another period of time.
    Current motion detection systems often use either passive infrared sensors or active motion sensors with radar or ultrasound technology. While infrared sensors react sensitively to thermal radiation, active motion sensors use the Doppler effect. In the case of radar sensors, the sensor emits an electromagnetic wave, which propagates in space and is reflected by objects. The reflected electromagnetic wave is received by the sensor and compared with the emitted signal. If the situation in the room changes, for example as a result of the movement of a person, the received signal will also change according to the size and the direction of movement of the person. This change in the signal can be evaluated and recorded for the detection of the moving person.
    However, self-motion of such a sensor also causes a change in the received signal. For this reason, such systems must basically be permanently mounted, for example on a ceiling or on a wall. However, such a mounting structure may be subject to vibration, vibration or vibration caused, for example, by the closing of doors or the operation of motors, e.g. in elevators, be evoked. For example, gypsum plaster ceilings sometimes cause slight vibrations.
    The described disturbances can cause motion detectors to erroneously detect a movement. For many systems, it is therefore recommended to install them only in a vibration-free environment. Moreover, there are systems in which it is attempted to isolate the detector system from any form of external shock, for example by means of dampers or the like. Typically, however, such systems are elaborately designed, expensive and maintenance-prone. In each
    In this case, it has proved difficult to completely eliminate the influence of shocks and other disturbances.
    SUMMARY OF THE INVENTION
    Against this background, the present invention has the object to enable a simple movement detection, which works precisely even with external shocks and vibrations.
    According to the invention this object is achieved by a motion detector with the features of the main claim 1, a light system with the features of the independent claim 11 and / or a method having the features of the independent claim 12th
    The solution according to the invention provides a motion detector with a relative movement sensor for detecting a momentary relative movement of an object located in a sensitive area of the motion detector with respect to the motion detector. The motion detector further comprises a self-motion sensor for detecting a momentary self-motion of the motion detector and / or the relative motion sensor. Furthermore, the motion detector comprises a control unit for controlling the motion detector as a function of the instantaneous relative movement of the object detected by the relative motion sensor and the instantaneous movement of the motion detector and / or the relative motion sensor detected by the proper motion sensor.
    The solution according to the invention further provides a lighting system with a motion detector according to the invention. The
    Lighting system has at least one lighting unit, which is coupled to the motion detector such that the lighting unit can be controlled by the motion detector.
    The solution according to the invention also provides a method for controlling a motion detector. The method comprises the method step of detecting a momentary relative movement of the object with respect to the motion detector in a sensitive area of the motion detector by means of a relative movement sensor of the motion detector. Furthermore, the method comprises the method step of detecting a momentary inherent movement of the motion detector and / or the relative motion sensor by means of a self-motion sensor of the motion detector. Furthermore, the method comprises the method step of controlling the motion detector by means of a control unit of the motion detector as a function of the detected instantaneous relative movement of the object and the detected momentary proper motion of the motion detector.
    One idea underlying the present invention is to equip a motion detector with two separate sensors. The one sensor is in this case designed as in conventional motion detectors for detecting relative movements of objects with respect to the motion detector. In addition, in the solution according to the invention now a second sensor, which can detect the proper motion of the motion detector. The self-motion can be taken into account by the control unit to determine whether an actual movement of objects in the sensitive area of the motion detector is present or rather the motion detector is impaired by disturbing influences such as shocks.
    A particular advantage of the aspect of the inventive solution based on this idea is that potential interference influences of the motion detector, such as, for example, vibrations of the motion detector, vibrations or impacts or the like, can be explicitly taken into account. Unlike conventional motion detectors is not trying to mitigate or mitigate these effects more or less satisfactory. In the case of the present solution, on the contrary, these influences are in principle even measurable, so that proper movements of the motion detector can be determined.
    For example, a relative movement of an object is detected when the motion detector is activated, without at the same time a self-motion of the motion detector can be detected. In this case, it is the detection of an actual movement of an object in the sensitive area of the motion detector and the motion detector will consequently report a movement.
    In another example, when the motion detector is activated, a relative movement of an object is detected and, at the same time, a vibration of the motion detector. In this case, for example, in a simply designed embodiment of the invention, it could be determined that in principle no movement is reported. The motion detector is virtually unable to detect actual movement due to the detected vibration. If necessary, a magnitude of the shock could also be included by means of a threshold value. In this case, the motion detector would report, for example, only in the case of particularly strong vibrations beyond the threshold, no movement of the object.
    However, the present invention furthermore offers the possibility of determining, by a detailed comparison of the relative movement and the proper movement of the motion detector, whether the relative movement has arisen solely by the motion of the motion detector or if an object has actually moved in the sensitive area of the motion detector and Motion detector, for example, at the same time additionally experienced a shock.
    The motion detector according to the invention can be provided in a lighting system and, for example, turn on or off the lighting units located therein when detecting a moving object. In principle, basic other functions for controlling the lighting units are also provided, such as dimming, color changing or the like.
    The above description assumes that the motion detector forms a device which may, for example, be adapted for attachment to a wall, ceiling or floor of a building to which both the relative motion sensor and the intrinsic motion sensor are rigidly connected. In this case, it is expedient that the intrinsic motion sensor is designed to detect a momentary intrinsic movement of the motion detector per se. In principle, however, other embodiments of a motion detector or a motion detector system are possible in which the mentioned components are not rigidly connected together in a device, for example within a housing. Thus, the intrinsic motion sensor can in principle also be attached to a wall separately from the relative motion sensor, but nevertheless be coupled with it. In such more general cases, the intrinsic motion sensor can therefore be designed to detect a momentary intrinsic movement of the relative motion sensor, since this or its movement state is ultimately decisive for the detection of an actual movement of objects.
    Advantageous embodiments and further developments will become apparent from the other dependent claims and from the description with reference to the figures.
    According to a development of the motion detector, the relative movement sensor is designed for transmitting and receiving electromagnetic waves. In particular, the relative movement sensor can be designed for transmitting and receiving microwaves and / or radio waves. The relative motion sensor may include, for example, a radar module for detecting the instantaneous relative movement of an object by means of radar. The radar waves are radiated, for example continuously or pulsed in the sensitive area of the motion detector. The radar module can therefore be designed as a pulse radar o-the continuous wave radar. The waves are now reflected by objects in the sensitive area and then received back by the motion detector. If the arrangement of the objects in the sensitive area changes or if an object moves into or out of the sensitive area, the received wave spectrum changes. Based on this, relative movements between the motion detector and the objects can be detected.
    According to an alternative development, the relative motion sensor is designed for transmitting and receiving ultrasonic waves. According to the development by means of electromagnetic waves and ultrasonic waves, i. Sound waves, suitable for the determination of relative movements.
    Furthermore, the relative movement sensor can be designed to detect the instantaneous relative movement of an object by means of Doppler analysis of waves transmitted and received by the relative motion sensor. For example, radar waves are radiated into the sensitive area. The waves are reflected by objects, such as a moving person, and received again with a certain Doppler shift. The Doppler shift serves as a measure of the relative movement, for example, the relative speed of the person with respect to the motion detector. By contrast, static objects do not generate a Doppler shift, so that only moving objects are detected. By comparing the transmitted and the received frequency, in particular the radial velocity component of the moving object with respect to the motion detector can be determined. A motion detector based on the Doppler effect thus reacts particularly well to changes in distance between objects and the motion detector.
    Accordingly, in the step of detecting a momentary relative movement of the object with respect to the motion detector, the method may comprise the Doppler analysis of waves transmitted and received by the relative motion detector.
    In a development, the intrinsic motion sensor is designed to detect vibrations, shocks, and / or shocks. The self-motion sensor may include an acceleration sensor and / or vibration sensor for this purpose. Acceleration sensors exist in a variety of configurations. They are cheap and can be produced in miniaturized form. Miniaturized sensors are usually designed with piezoelectric elements or as MEMS (micro-electro-mechanical cal system). This makes them ideal for saving space in a motion detector.
    In a development, the intrinsic motion sensor is designed to detect changes in position. The self-motion sensor may include a gyroscopic sensor for this purpose. In this development, especially rotational movements, i. Angular changes, or more general changes in position of the motion and / or the relative motion sensor taken into account. In conjunction with an acceleration sensor, this development provides a more detailed picture of the proper motion of a motion detector.
    In a development, the control unit comprises a comparator circuit. In this development, the control unit may, for example, receive analog relative motion signals from the relative motion sensor and analogue eigenmotion signals from the intrinsic motion sensor, optionally filter them and subsequently link, digitize and further process them by means of the comparator circuit. As an alternative to a digital version, however, the control unit can also be present in an analogue manner. Depending on the applica tion purpose, this may be advantageous, since the motion may thus possibly cheaper or more durable, energy-efficient and robust.
    In a development, the control unit comprises a microcontroller. In this case, the control unit is designed to process digital data or signals. The control unit can thus be present as an integrated circuit in a highly miniaturized form. Both the relative motion sensor and the intrinsic motion sensor can each deliver analog or already digitized signals to the control unit. In the case of analog signals, the control unit digitizes the signals, for example by means of a comparator circuit following an upstream filter, before processing them further. In this development, the control unit can continue to be connected to data networks by means of a wireless connection. Thus, for example, a user could directly access the motion detector from a computer, for example for maintenance or updating purposes.
    In a further development of the method, this may include the method step of controlling at least one lighting unit coupled to the motion detector by means of the motion detector. For example, the driving may include turning on and / or off the lighting unit. In principle, complex controls of the lighting units are also provided, e.g. Up and / or down dimming. In particular, the motion detector may include a timer so that light units may be periodically turned on or off. For example, a counter can be started when motion is detected. When the motion detector detects a new movement, it can reset the counter to zero. The light units remain turned on until the meter reaches a certain duty cycle. This ensures that the light units are not turned off as long as an object is in the sensitive area. Alternatively, the lighting units can also be switched off after expiration of a switch-on period and, if necessary, switched on again, provided that a movement is still registered at this time.
    In a development of the motion detector, the control unit can be designed to determine an absolute movement of the object in the sensitive area of the motion detector. In a corresponding further development of the method, the method step of controlling comprises determining whether an absolute movement of the object is present in the sensitive area. In this development, therefore, in particular an absolute movement of objects within the sensitive area of the motion detector can be detected. In this case, not only, for example, would the presence of a shock be detected, but the actual proper motion of the motion detector could be used for the explicit determination of the absolute motion of the object in the sensitive area based on the relative motion of the object.
    The above embodiments and developments can, if appropriate, combine with each other as desired. Further possible refinements, developments and implementations of the invention also include combinations, not explicitly mentioned, of features of the invention described above or below with regard to the exemplary embodiments. In particular, the skilled person will also be individual aspects
    Add improvements or additions to the respective basic form of the present invention.

    DESCRIPTION OF EMBODIMENTS
    Fig. 1 shows a schematic representation of a lighting system according to the invention with a motion detector according to one embodiment.
    In Fig. 1, reference numeral 1 denotes the motion detector and reference numeral 8 denotes the lighting system. The motion detector 1 comprises a relative movement sensor 2 and a self-motion sensor 3. Both sensors are connected within the motion detector 1 to a control unit 4. The control unit 4 is in turn connected to a plurality of light units 9 of the light system 8.
    The motion detector 1 can be installed, for example, on a building wall (not shown). Alternatively, however, embodiments are provided in which such a motion detector 1 is mounted in a ceiling or in a floor of a building. In principle, however, a motion detector 1 according to the invention can also be installed inside buildings, in or on vehicles or other moving objects.
    In the illustrated embodiment, the motion detector 1 is configured to monitor a sensitive area 10 on the building. For this purpose, the motion detector 1 is equipped with a relative motion sensor 2, which is designed for transmitting and receiving radar waves. Accordingly, the relative motion sensor 2 may include, for example, a radar module having pulse radar or continuous wave radar technology (e.g., FMCW radar). Depending on the embodiment, the relative movement sensor 2 can therefore be designed to transmit and receive continuous or pulsed electromagnetic waves. When the motion detector 1 is activated, the relative motion sensor 2 transmits waves of a certain frequency, e.g. 24 GHz into the sensitive area 10. Since radar waves or microwaves penetrate matter, such a motion detector 1 can be made almost invisible behind a variety of non-metallic materials, e.g. Plastics, wood or ceramics. The radar waves are reflected by objects 11 in the sensitive area 10 and then received by the relative motion sensor 2. For example, the relative motion sensor 2 may be formed with separate transmitting and receiving antennas or modules.
    If one or more objects 11 moves within the sensitive area 10, the radar waves receive a Doppler shift. The Doppler shift serves as a measure of the relative movement, for example, the relative speed of a person with respect to the motion detector 1. Static objects 11, however, generate no Doppler shift and can be distinguished from moving objects 11. The relative movement sensor 2 is now designed to detect, with the aid of a Doppler analysis of the transmitted and received radar waves, whether objects 11 are currently moving in the sensitive area 10 relative to the motion detector 1.
    Furthermore, the motion detector 1 is equipped with a self-motion sensor 3. The self-motion sensor 3 is in this case designed to detect a momentary intrinsic movement of the motion detector 1. For example, the self-motion sensor 3 may be an acceleration sensor that can detect vibrations or other accelerations of the motion detector 1. Alternatively or additionally, however, it may also be a sensor which is specially designed for detecting vibrations.
    The relative movement sensor 2 detects the instantaneous relative movement in the form of relative movement signals 5, which are provided to the control unit 4. Likewise, proper motion signals 6 are transmitted to the control unit 4 by the self-motion sensor 3. The control unit 4 is designed to match the relative motion signals 5 with the intrinsic motion signals 6 and, based on this, to determine whether an object 11 moves in the sensitive area 10. Here, in principle, depending on the embodiment of the invention, an absolute movement of an object 11 can be determined and not, as in the case of conventional motion detectors, only a relative movement with respect to the motion detector. If the motion detector 1 vibration, vibration or the like to be exposed, so this is detected by the intrinsic motion sensor 3 and taken into account by the control unit 4 accordingly.
    The exact determination of the movement of objects 11 in the sensitive area 10 is carried out by a microcontroller 12 installed in the supply unit 10. The microcontroller 12 is further configured to control or control the lighting units 9 connected to the motion detector 1 within the lighting system 8. For this purpose, the control unit 10 sends control signals 7 to the respective lighting units 9. If, for example, a movement of an object 11 is detected, the control unit 10 causes the lighting units 9 to be switched on. However, the control unit 10 and the light system 8 are not limited to this minimum functionality, but modifiable in a variety of ways.
    For example, the motion detector 1 may include a timer (not shown) so that light units 9 can be periodically turned on or off. For example, a counter can be started when motion is detected. If the motion detector 1 then detects a new movement, he can reset the counter back to zero. The lighting units 9 remain in this case turned on until the meter reaches a certain duty cycle. This ensures that the lighting units 9 are not switched off as long as an object 11 moves in the sensitive area 10. Alternatively, the lighting units 9 can basically be switched off after expiry of a switch-on period and, if necessary, switched on again, provided that a movement is still registered at this time.
    Furthermore, the motion detector 1 may comprise a photosensitive twilight switch or the like. This can be made sensitive to the ambient brightness. With the help of such a twilight switch can be set, for example, that the motion detector 1 is automatically activated only from a certain darkness threshold. The light units 9 are thus only turned on when darkness prevails.
    In principle, the movement detector 1 according to the invention can also be coupled with an alarm or the like alternatively or in addition to lighting systems 8. In this sense, the motion detector 1, for example, be part of a burglar alarm system or the like.
    FIG. 2 shows a schematic representation of signals of the motion detector 1 from FIG. 1 according to an embodiment.
    In Fig. 2, output signals of the individual components of the motion detector 1 are schematically represented by output amplitudes as a function of time for two examples. The illustrated output amplitudes are to be seen here purely by way of example and may correspond, for example, to voltages or other suitable measured variable. The connection of the individual signals described below is purely exemplary in nature.
    The first example "person" corresponds to the detection of a person 11 who moves in the sensitive area 10 of the motion detector 1. The second example "vibration" corresponds to the detection of a vibration of the motion detector 1, without simultaneously a person 11 in the sensitive Area 10 moves.
    Among the reference numerals of the individual components of the motion detector 1, i. the relative motion sensor 2 and the self-motion sensor 3, 2 analog output amplitudes of the components for the two examples are shown in FIG. The relative motion sensor 2 detects in both examples, a relative movement, in the first example because a person 11 actually moves within the sensitive Be rich 10, in the second example due to the proper motion of the motion detector 1 by the vibration. The output amplitude of the relative motion sensor 2 is further processed in digital form as a relative motion signal 5 by the control unit 4. For example, the relative movement sensor 2 may be designed so that when a predetermined threshold value 13 is exceeded, a relative movement signal 5 is generated by the output amplitude of the relative movement sensor 2.
    The self-motion sensor 3 does not detect any self-motion of the motion detector 1 in the first example. In the second example, however, a vibration is detected so that an increased output amplitude of the self-motion sensor 3 occurs. The output amplitude of the eigenmotion sensor 3 is further processed in digital form as a proper motion signal 6 by the control unit 4. By way of example, the intrinsic motion sensor 3 can be designed such that a self-motion signal 6 is generated by the output amplitude when a predetermined threshold value 13 is exceeded or undershot. In the example of FIG. 2, the natural motion signal corresponds to a logical one, unless proper motion is detected with an output amplitude above / below the predetermined threshold 13, and a logical zero, if the output amplitude of the intrinsic motion is above / below the predetermined threshold 13. Conversely, the relative motion signal 5 corresponds to a logical one when a relative movement is detected.
    The relative movement signals 5 and the proper movement signals 6 are compared with each other by the control unit 4 and, based on this, a control signal 7 is generated. In the exemplary embodiment in FIG. 2, the relative movement signals 5 and the proper motion signals 6 are simply combined with each other with a logical AND operation. The control signal 7 thus always corresponds to a logical one when a relative movement is present, without at the same time a vibration has been detected.
    This means that the exemplary motion detector 1 only turns on the light units 9 coupled thereto when a relative movement of an object 11 is detected without a simultaneous vibration of the motion detector 1 being present. The lighting units are thus not turned on, in particular, if only one vibration of the motion detector 1 is present.
    This exemplary relative motion sensor 2 can not practically distinguish vibrations from moving persons 11. Thus, if a concussion is detected simultaneously with the detection of the relative movement of an object 11, this motion detector 1 basically does not signal any movement.
    In principle, however, significantly more complex signals and signal processing are provided according to the invention, so that, for example, even complex movement patterns of several objects 11 with simultaneous vibrations of the motion detector 1 can be handled. Furthermore, it can also be provided that absolute movements of objects 11 in the sensitive area 10 are determined. For this purpose, detailed information about the proper motion of the motion detector 1 and the relative movement of the objects 11 can be used.
    FIG. 3 shows a schematic representation of a method 20 according to the invention for the lighting system 8 from FIG. 1 according to one embodiment.
    The method 20 includes, under the reference numeral 21, the method step of detecting a momentary relative movement of an object 11 with respect to the motion detector 1 in a sensitive area 10 of the motion detector 1 by means of a relative motion sensor 2 of the motion detector 1. Further, the method 20 includes the method step of reference numeral 22 Detecting a current proper motion of the motion detector 1 and / or the relative motion sensor 2 by means of a self-motion sensor 3 of the motion detector 1. Furthermore, the method 20 includes the reference numeral 23, the method step of controlling the motion detector 1 by means of a control unit 4 of the motion detector 1 in response to the detected current Relative movement of the object 11 and the detected instantaneous natural motion of the motion detector 1 and / or the relative movement sensor 2 is compared.
    The method step of detecting a momentary relative movement of the object 11 relative to the motion detector 1 in this case comprises the Doppler analysis of waves transmitted and received by the relative motion detector 2. Furthermore, the method 20 includes by reference numeral 24 the method step of driving at least one light unit 9 coupled to the motion detector 1. The method step of controlling may include determining whether an absolute movement of the object 11 is present in the sensitive area 10.
