Definitions

  • the invention relates to a method for access security, in which an access of authorized persons to a protected area allows and access by unauthorized persons is prevented.
  • the invention further relates to an apparatus for access control and an elevator car.
  • the known access control systems include a review of each individual person wishing to enter.
  • an elevator with access control is made possible by two spatially separated motion detectors with different reception field characteristics, with one motion detector on and the other outside the elevator.
  • the motion detectors are designed in such a way that a person passing through the reception field triggers a signal in the receiver of the motion detector.
  • the description of the European patent application EP 0 940 775 A2 discloses a passthrough lock and method for operating such a pass-lock.
  • the passage lock has a non-contact access control device based on a transponder system. Furthermore, sensors on the doors of the passage lock allow registration of the number of persons passing through the lock.
  • An elevator user carries an information provider, wherein the information provider transmits individual data such as weight and body dimensions of the elevator user and a desired destination floor to a detection device within the elevator.
  • the information transmitter described uses electromagnetic waves for information transmission.
  • the current weight of the elevator is determined by a separate unit.
  • the measured weight gain of the elevator is compared to the transmitted weight data of the ascent elevator user through a comparator unit. If there is a match between the measured weight increase of the elevator and the transmitted weight data, the comparator unit sends a release signal to an elevator control, so that the elevator is activated. Elevator users without information providers are determined by determining the weight increase of the elevator, wherein a determined increase in weight of the elevator to which there are no transmitted weight data lead to an interruption of the lift operation.
  • US 4,847,485 a device for determining the number of persons and the direction of movement within a space to be monitored or a transit lock.
  • a device for determining the number of persons and the direction of movement within a space to be monitored or a transit lock By means of at least two infra-red sensors fastened in a passage area at a fixed angle, temporal courses of the ambient temperature are measured.
  • the passage area can only be entered using a badge reader, so that it is checked by taking advantage of the specific temperature curves, whether the number of persons entering the transit area is equal to the number of badges detected by the badge reader.
  • the US patent US 5 555 512 discloses an image processing apparatus for processing infrared images measured with an infrared sensor.
  • the infrared image shows the heat distribution within a certain area.
  • the image processing apparatus also has an image processing unit for extracting personal data as well as environmental characteristics based on the infrared images. For this purpose, representative points of an area representing a person within the infrared image, a number of areas representing persons and a number of pixels within the areas are determined. In addition, average temperatures of the areas and positions of limbs of the persons are determined.
  • the invention has for its object to provide a generic method that is suitable for a fast and reliable determination of a number of persons and for an authorization check. Furthermore, the protection against ingress of unauthorized persons is further improved.
  • the invention is further based on the object to provide a generic device for carrying out the method.
  • the invention is also based on the object to provide an elevator car that allows a contactless and reliable determination of the number of persons located in the elevator car.
  • this object is achieved in that a generic method is developed so that, taking into account optical data and the detection of persons radiated heat radiation, a number of persons located in a check area is determined that the detected heat radiation compared with the optical data and that's the result of this Comparison in the determination of the number of persons is received, whereby a number of existing in the area credentials and the number of persons with the number of credentials is compared and that in the case that the number of people with the number of credentials matches, an access release signal is generated, and further wherein positions of the authorization cards are determined, so that by a comparison between a thermal image and the determined positions of the authorization cards (actually transponder), a determination of a position of a person who does not carry a badge takes place.
  • the access enable signal can be displayed, for example, optically or automatically unlock an access mechanism.
  • the invention uses the idea of not individually checking permissions of persons, but to detect a number of persons and a number of credentials and to compare these - preferably independently determined - numbers with each other.
  • the determination of the number of persons and the number of authorization cards preferably takes place substantially simultaneously in order to avoid manipulation.
  • the access release signal controls an access device, the access device enabling access of all persons located in the checking area.
  • the number of persons in the check area and the credentials in the check area are compared in a computer.
  • the term computer is in no way limiting. This may be any unit suitable for performing calculations, for example a workstation, a personal computer, a microcomputer or a circuit suitable for performing calculations.
  • An expedient embodiment of the invention is characterized in that the heat radiation emitted by the persons is detected to determine the number of persons.
  • This embodiment has the advantage that a count of other heat sources, such as cigarettes, is avoided as persons.
  • the detected thermal radiation is compared with the optical data and that the result of this comparison is included in the determination of the number of persons.
  • An expedient embodiment of the method is characterized in that electromagnetic radiation emitted from the inspection area is detected and that sources of electromagnetic radiation having a predetermined beam characteristic are recorded as authorization passes.
  • a particularly preferred embodiment of the invention provides that the inspection area substantially corresponds to an inner surface or the interior of an elevator car.
