Definitions

  • the invention relates to an intrusion detector according to the preamble of patent claim 1.
  • intrusion detectors are known for example from DE-A-22'16'236. They consist of one Combination of a passive infrared detector and an ultrasound detector, which are combined in an AND circuit are connected. The infrared part reacts to the body radiation of a person in the infrared Spectral range and the ultrasound part on the frequency shift caused by the Doppler effect of ultrasound reflected from a moving intruder. By combining both principles prevents an unwanted intrusion of a person into a protected area with greater security and detect selectivity as using only a single detection method. A faulty one In this way, alarm signaling can be avoided with greater certainty.
  • Passive infrared intrusion detectors are known for example from EP-A1-0'189'536. You serve an object that has entered a monitored area, e.g. an intruder, by means of this Detect emitted infrared radiation and trigger an alarm signal via an evaluation circuit.
  • a corresponding number of spatially distributed sensitivity areas is formed, when they are penetrated by an intruder, a change in radiation of the sensor and thus a Alarm signal is generated.
  • the sensor can have a single sensor element, or it can be a Multiple or dual sensors can be designed with two or more separate sensor elements or flakes, whereby the number of sensitivity ranges is at least doubled.
  • the housing of the detector is closed in the direction of irradiation by a window, that for the infrared radiation to be detected, e.g. for the body radiation of a person in the area from about 5 to 15 ⁇ m, preferably between 7 to 12 ⁇ m, permeable, but for shorter-wave radiation is largely impermeable.
  • This window can in turn be optically bundled, e.g. as a Fresnel lens, which generates the desired sensitivity ranges, so that, if necessary, on mirror segments can be dispensed with.
  • ultrasonic intrusion detectors e.g. from CH-A-556'070 or EP-A1-0'158'022, known. These have an ultrasound emitter that emits ultrasound at a frequency of over 20 kHz monitored area in front of the detector, as well as an ultrasound receiver, which from the room records reflected ultrasound and feeds it to an evaluation circuit. While fixed objects only ultrasound reflect with the transmit frequency, a moving intruder causes a frequency shift after the Doppler effect. The evaluation circuit triggers an alarm signal when this frequency shift corresponds to values that are typical of a moving person and if so at the same time an infrared radiation is received, which is characteristic of human intruders.
  • the window is transparent to infrared radiation through an infrared radiation source attached to the outside of the housing, which passes through the window radiates on the sensor to monitor. If this radiation is absent or reduced, a Fault signals. In this way, however, only a radiopaque one lying directly on the window can Layer can be detected, but no objects just in front of the detector or at a certain distance of this.
  • infrared intrusion detector known from EP-A2-0'274'889 is an infrared sensor combined with a microwave system in a logic circuit that only triggers an alarm signal, when both systems emit a signal at the same time.
  • the infrared sensor between the microwave transmitter and receivers arranged immediately adjacent to them behind the entrance window.
  • One try, to cover the window or to provide it with a spray layer or to install a shield in front of the window, can be detected by the microwave part.
  • this can only be used to identify objects reflect or absorb the microwaves, i.e. preferably metallic conductive materials, but straight not many films that are opaque to infrared radiation and often used for sabotage attempts or paints.
  • the object of the invention is to overcome the above-mentioned disadvantages of the prior art eliminate and in particular to create a combined intrusion detector of the type specified at the outset, an attempt to sabotage or reduce functionality by using a shield Can detect and signal with greater security and with less effort.
  • Such a temporal change in the ultrasound field exists e.g. in a change in sound pressure or the duration of the ultrasound reflected by objects in the monitored room. As soon as such a measurand changed compared to an earlier point in time or to an average from previous measurements is an indication that a change has been made in the room, e.g. a shield in the room was placed.
  • a temporal parameter change of the sound field can easily be done by the Doppler frequency evaluation processed separately.
  • Ultrasonic emitters and receivers are preferably arranged on different sides of the entrance window, so that the ultrasonic field covers the window area. Instead, it can be beneficial Ultrasound emitter and receiver to be placed adjacent to the same side of the window and the ultrasound by means of reflectors, which are arranged on one or different sides of the window, over the window to lead.
  • the exit surface of the ultrasonic emitter and the entry surface of the ultrasonic receiver are particularly advantageous on both sides of a plane formed by the front wall of the housing at the location of the window arranged so that at least one acoustically effective surface of the ultrasonic components, e.g. Emitter, Receiver or a reflector lies within the recess. It is of particular advantage, for example in the Level the front wall in front of the window with fine openings, at least for the most part cover that is permeable to infrared radiation and ultrasound, e.g.
  • a fine-mesh grid or a perforated one Foil to be provided and arranged in such a way that the front surfaces of the ultrasound emitter and receiver lie on different sides of the cover and thus the cover from the ultrasound generated is irradiated. This will result in an attempt at impermeability, e.g. by spraying, supervised
  • the intrusion detector according to the invention has both an infrared part and an ultrasound part anyway it can advantageously be carried out without a significantly increased effort by means of a temporal ultrasound field evaluation, as well as an infrared window monitoring device known in principle, which optimizes security against sabotage and reduces the susceptibility to false alarms.
  • the infrared intrusion detector shown in Figure 1 has a housing 1, preferably made of plastic, on. Inside the housing 1 there is infrared radiation in the evaluated spectral range from 5 to 15 ⁇ m, in particular from 7 to 12 ⁇ m, highly reflective, preferably made of metal, mirror or reflector 2 arranged, for example, as described in EP-A1-0'189'536 or in another suitable manner can be designed as a segment mirror to cover a number of spatial sensitivity ranges form.
  • the part 3 adjoining the mirror segments is used to shield electromagnetic fields from the circuit board 4 arranged in front with the components of the evaluation circuit mounted thereon. This is set up so that one moves an intruder through a range of sensitivity generated radiation change of the sensor, i.e.
  • the infrared sensor 5 On the lower part of the board 4 is the infrared sensor 5 is attached, which is designed, for example, as a pyroelectric sensor and at least in the spectral range is sensitive to human body radiation This sensor 5 can be a single radiation-sensitive Have element or as a multiple or dual sensor with at least two neighboring Sensor elements are designed.
  • Shield 6 In front of the circuit board 4 there is another electromagnetic one Shield 6, e.g. from a suitable metal sheet.
  • an entry window 9 is provided in a recess 8 through which infrared radiation incident on the detector and pass through the reflector 2 onto the sensor 5 can reach.
  • the window 9 is off made of a material that is preferably for human body radiation, i.e. in the wavelength range of 5 to 15 ⁇ m, especially 7 to 12 ⁇ m, is permeable, e.g. from a suitable plastic such as polyethylene, Special glass or silicon.
  • the window also protects the inside of the detector, especially the optical one Reflectors 2 and the sensor 5 from damage and dust.
  • the window can also be used as an optical effective element, e.g. as a Fresnel lens in order to concentrate and generate radiation from separate sensitivity areas.
  • the detector is equipped with a device for detecting and signaling such a function-reducing Shield equipped
  • this consists of one provided on one side of the radiation entrance window 9 Ultrasound emitter 10 and an ultrasound receiver lying on the opposite side of the window 9 11.
  • the emitter 10 sends ultrasound in the frequency range slightly above the hearing range off, for example in the frequency range around 25 kHz.
  • An ultrasound field US1 is thus formed in front of the detector, which is present during the attachment a sound-shielding wall in front of the detector changes
  • the receiver 11 is connected to a suitable one Evaluation circuit connected, which triggers a fault signal when the one registered by the receiver 11 Ultrasound changes in a predetermined manner, as is the case for applying a shield in front of the detector is characteristic.
  • the intensity of the received ultrasound and its time course with the measurement results obtained at an earlier point in time or formed from previous measurements Averages were compared and deviations identified for changes in the monitored room are typical of the detector.
  • the intrusion detector contains an ultrasound device anyway, this can be surprising Advantages and without special additional effort for function monitoring of the infrared part of the intrusion detector be used. It is only necessary to do this on the front side 7 of the housing, as in Figure 2 and 3a shown to arrange the ultrasonic emitter 10, 12 so that the in the room in front of the detector emitted ultrasound forms an ultrasound field in front of the infrared window 9.
  • the evaluation circuit is then trained so that it triggers an alarm signal when the ultrasound reflected from a moving object a predetermined frequency shift corresponding to the moving speed of the object shows and at the same time the infrared part emits an output signal and a fault signal when the received Ultrasound shows a certain change compared to earlier times
  • the required for this Circuit can be integrated easily and without great effort into the existing evaluation circuit.
  • the described device is capable of providing an infrared shield in front of the detector in one determine large distance range with great certainty, a shield applied directly to the window 9 cannot be grasped easily.
  • a shield applied directly to the window 9 cannot be grasped easily.
  • the window could still be reached with a spray.
  • a fine mesh Act as it is used to protect screens or as an insect screen, or a film with fine holes, e.g. made of polyethylene.
  • the openings should be one size have at most in the range of tenths of a millimeter, so that they are closed by spraying and this makes the cover impermeable. If now, as shown in Figure 3b, the sound exit surface of the Ultrasonic emitter 10 is mounted inside the recess 8 behind the cover 14, the surface of the receiver 11, however, on the front 7 outside the cover 14, the ultrasound normally penetrates the cover 14 through the openings. However, it is sprayed on when the openings are closed Paint blocked so that a sabotage attempt is recognized and reported here too.
  • an infrared radiation source 15 can be provided, which through the window 9 through an optical Reflector 16 irradiates the sensor 5. If this radiation is absent or reduced, in itself generates a disturbance signal in a known manner.
  • Two ultrasound emitters and receivers can be provided However, as shown in FIG. 4, there can also be only a single ultrasound emitter 17 and a receiver 18 be attached to the same side of the window 9.
  • the ultrasound is here from the emitter 17 via one or several acoustic reflectors 19, e.g. Sheet metal strips, fed through the window 9 to the receiver 9.
