Definitions

  • the invention relates to a motion detector according to the preamble of claim 1.
  • PIR motion detector For the detection of heat radiation emitting, moving objects, in particular of people, passive infrared motion detectors are usually used (PIR motion detector). These are preferred in the room to be monitored installed on a wall and equipped with infrared light-sensitive sensor elements, to which the emitted heat radiation is fed via a receiving optic is that movements of heat-emitting objects on the sensor elements produce electrical signals. With these you can then use an electrical circuit a switching signal is generated, which is used to switch a lighting device or a warning system.
  • the switching signal returns to its initial state after a delay back as soon as no movement is detected. Does the device serve z. B. in one Office for switching the lighting, the lighting device is then also switched off, when the movements of an employee sitting in his office chair are so small that they can no longer be detected by the motion detector. Switching off the lighting on this is not only for the overlooked Employees unpleasant, but cost more energy, because then often with larger delay times must be worked. There is therefore a clear one Requirement for presence detectors, which may then also be used for purposes other than light switching could be used.
  • thermo- and pyroelectric infrared measuring system as well as an optoelectronic measuring system in connection with a Fuzzi logic processor.
  • the Fuzzi logic concludes on the basis of three measurement results and enables presence detection, however, only at short distances to the detector.
  • DE 36 16 374 A1 also discloses a pyrodetector which is suitable for motion and direction-selective detection.This sensor works with a number of individual sensor elements arranged as an array, but the known systems are either relatively complex to implement or are insufficient sensitive to capture even the smallest movements.
  • the object of the invention is therefore a motion detector according to the preamble of claim 1 to create that even very slight movements still reliably detect can.
  • the sensitivity of the sensor is significantly increased by the fact that one element array each is arranged in a confined space so that there is a radiation reception forms a suitable pixel, which is followed by its own signal processing stage. This arrangement is multiplied by that provided by several such pixels Pixel array is formed, which covers a radiation-sensitive receiving area, which has a predetermined reception structure. Because the individual element arrays are compensated with respect to constant light, which e.g. through a series connection opposite polarity sensor elements can happen, each pixel works with high sensitivity, but without being susceptible to constant light, so that even the smallest movements of a radiation object can be detected.
  • the signal processing stages assigned to the individual pixels together with a logic unit enable the signal evaluation according to a predefined or selectable algorithm in the desired one Way can be done.
  • a suitable switching signal can be identified by a Control circuit can be generated.
  • the Reception optics is constructed as a multi-lens or mirror optics.
  • the reception structure the pixel array depends on the arrangement of the individual pixels to each other.
  • a first option is to look at the individual pixels of the pixel array to arrange a flat surface next to each other like a chain.
  • Another possibility results when the individual pixels of the pixel array coaxially on a lateral surface a multi-lens or a mirror arrangement. According to each The selected arrangement results in different detection areas, however can also be influenced by the receiving optics.
  • a selection effect of the receiving device with which a location can be determined and have the direction of movement determined can be achieved that each pixel with the part of the receiving optics assigned to it points to a specific is delimited compared to other room areas.
  • Another expedient development of the subject matter of the invention provides that in the signal processing stage or the logic unit an evaluation of each Pixel emitted signal is such that the size of the radiating Object and / or its speed and / or its direction of movement can be determined is.
  • the logic unit only then the control circuit activated to switch off a lighting device if none of the pixels emits a signal within a predetermined period of time that exceeds a predetermined Threshold lies.
  • the reliability of the activation can be increased by that the logic unit only then the control circuit for turning on a lighting device activated if at least two of the pixels within a given Output a time period that is above a predetermined threshold.
  • the logic unit it is advantageous to build the logic unit using a microprocessor and in In terms of miniaturization, it is also expedient to use the pyroelectric as a pixel array Sensor, the signal processing stage and the logic unit in one Integrated circuit.
  • the signal processing stage and the logic unit can then manufactured in CMOS technology and the individual pixels as pyroelectric thin-film elements be carried out.
  • an object to be detected in particular one person to be detected, a heat radiation 1 from, via a receiving optics 2 to a pyroelectric sensor 3 arrives.
  • the receiving optics 2 exist in the present Example from a lens system, which is usually constructed as a multi-lens.
  • a mirror optic could replace the lens system, the mirror segments then facing each other because of their reflective effect the sensor 3 would be arranged differently accordingly.
  • the detection area defined by the lenses of the receiving optics 2 is divided to a large number of individual pixels 4, each of these pixels 4 thereby Compensated against constant light radiation is that at least two opposite poles in series switched sensor elements 5, 6 form a pixel 4.
  • the construction of the Pixel 4 from several Sensor elements 5, 6 is shown in FIGS. 3 and 5. Like the associated ones recognize opposite-pole series connections of the sensor elements 5, 6 in FIGS. 4 and 6
  • the pixel 4 is made up of two or four sensor elements 5, 6 formed, but a larger number can also be selected if a higher number Resolution within a pixel 4 is desired.
  • each pixel 4 is followed by its own signal processing stage 7, such that a plurality of signal processing stages 7 at a common Logic unit 8 ends. So it is possible for each individual pixel via its sensor elements 5, 6 differentially generated signals and then using the Logic unit 8 to summarize or to order and assign according to predetermined criteria weight in order to finally give a switching command via a control circuit 9, the z. B. switches a light source on or off.
  • Fig. 1 There are a large number of possible variants for the arrangement of the pixels 4.
  • the pixel array 3 by several on one flat surface lying pixels 4 formed. It is more appropriate for other applications to place the individual pixels 4 in the focal point of a lens assigned to them, so that in the case of a half-ring-like lens arrangement, the pixels 4 also on an arc would come. Accordingly, optics with spherically arranged lenses would have a corresponding arrangement of the individual pixels 4 results. These are easily overlooked Connections that do not need to be illustrated.
