Definitions

  • the present invention relates to a method for controlling the door position of an automatic door, the door position being controlled as a function of the presence or non-presence and the direction of movement of people present, the people present being illuminated with infrared light on the entrance area of the entrance, the infrared light being transmitted as an area beam the infrared light reflections originating from an illuminated person are recorded by an infrared camera and the temporal changes in the reflex images are shaped in a control and processing unit into signals for controlling an automatic door.
  • the CH patent 607 187 describes an optical-electrical device for monitoring certain areas, consisting of an objective, a prismatic grid moved in one or two axes, receiver groups and evaluation circuit.
  • the prismatic grid is the moving spatial filter, which alternately directs the light of the object pixels onto the recipient groups. Objects or people entering this sensor-swept room change zero interference and produce a signal that is above the zero level.
  • the system has the disadvantages that expensive optical parts are required, that a mechanical drive must be present and that difficult adjustments have to be made. Interfering light influences can impair the function.
  • Patent application GB 2 093 986 describes a similar system in which various optical components and an electronic evaluation are available.
  • One of the optical components is a spatial filter, which is shown as a faceted hemisphere.
  • individual sensors are arranged on the upper edge of a motor-operated door leaf and are directed towards the pivoting range of the door leaf.
  • the presence or absence of people in the swivel range can be determined on the basis of the reflections of emitted infrared light and, consequently, the door drive can be stopped in the presence of a person in this area.
  • a more differentiated detection of the objects in the anteroom and an equally differentiated interpretation of the reflections in the receiving part is required, which is why normal infrared motion or presence detectors of the type described above can no longer meet the high demands of a universal door control .
  • the range of movement of a high-speed folding door is monitored by means of an infrared transmitter and receiver.
  • IR transmitters and receivers attached to the left and right of a door opening form a vertical, triangular surveillance zone. Since the transmitter diodes have a beam scattering angle of approx. 20 °, the transmitter and receiver assigned to each other must be operated in a coded, pulsed manner.
  • the device optimally fulfills the function of a protective curtain, but is not suitable for the vestibule monitoring of an elevator door.
  • the present invention has for its object to provide a method and an apparatus which clearly shows the presence, quantity and intentions of people in the vestibule of an entrance and delivers logical signals to a door control.
  • FIG. 1 shows an elevator front level 11 with an elevator entrance 4 and a car 23 present.
  • a shaft door leaf is designated 22 and a car door leaf 21.
  • An infrared camera 1 with a lens 1.1 is installed in the cabin door fighter.
  • an infrared radiator 3 is installed below, which emit an infrared light 3.1 in the direction of the anteroom parallel to an anteroom surface 5.
  • FIG. 2 Above the elevator entrance 4, the infrared camera 1 is located on a camera holder 2 with a control and evaluation unit 10. On the anteroom surface 5 there is a person 7 with feet 6 and legs 6.1, who is in the X direction to the elevator front level 11 moved there.
  • the anteroom area 5 is divided into Y zones 8.1 to 8.4. 9 denotes a camera axis line.
  • X zones are denoted by 12 and an image edge by 13.
  • 1.1 denotes a photo lens
  • 1.2 an LCD microshutter and 1.4 an infrared filter.
  • the LCD microshutter 1.2 has vertical sealing columns 1.8 and a likewise vertically arranged CCD line image sensor 1.5 has sensor cells 1.7.
  • FIG. 5 shows a distorted image 18 of the antechamber surface 5 as it is projected onto the LCD microshutter 1.2.
  • Reflex images 14 originate from the feet 6 and legs 6.1 of the person 7.
  • the projection plane 17 is divided into a used area 15 and an unused area 16.
  • the area 15 used corresponds to the usable projection area on the LCD microshutter 1.2.
  • the images of the X zones 8.1 to 8.4 on the projection plane 17 are designated 8.11, 8.21, 8.31 and 8.41.
  • the infrared light 3.1 emitted by the infrared surface radiator 3 strikes the feet 6 and legs 6.1 of the person 7 located on the vestibule surface and is partially deflected from there towards the infrared camera 1 by reflection.
  • the infrared filter 1.4 only allows this reflected infrared light 3.1 to pass through, and consequently only the reflex images 14 are projected onto the front plane of the LCD microshutter 1.2.
  • the LCD microshutter 1.2 has, for example, 50 individually controllable columns 1.8, which are activated in sequence in a certain cycle and thus produce a periodically horizontally translucent vertical slot opening.
  • the sampling rate can be chosen to be very low because a flicker-free image does not have to be generated for a viewer and is, for example, at most 10 images per second, an image being understood as an entire horizontal pass through the LCD microshutter 1.2. This results in very small amounts of data, which a special processor system or a processor system in the elevator control system can process in parallel.
  • the image columns scanned in this way are focused by means of the cylindrical lens 1.3 and all on the same line projected onto the CCD line image sensor 1.5.
  • the CCD line image sensor 1.5 is continuously read out for each projected image column and switched on for the next image column.
  • the read values are buffered and processed according to the later description.
  • the image resolution in the X direction is at least five times greater than in the Y direction. This results in the fact that objects moving in the X direction towards the elevator front level 11 are detected at least five times more sharply than those which move in the Y direction, that is to say parallel to the elevator front level 11.
  • the reflex images 14 of an object moving in the Y direction are always projected onto the same sensor cells 1.7 in the CCD line image sensor 1.5, from which it can be clearly concluded that this object is not approaching the entrance.
  • the corresponding binary image data combined with the position of the current column opening, can be interpreted as a person's movement parallel to the entrance level 11.
  • FIGS. 2 and 3 A grid with Y zones 8.1 to 8.4 and X zones 12 is shown in FIGS. 2 and 3. This grid does not really exist and is only used to explain the image distortion and the effects derived from it.
  • Y zones closer to the photo lens for example zone 8.1, are shown larger on the projection plane 17 than more distant Y zones such as Y zone 8.4.
  • the practical effect is that a person 7 moving at a constant speed in the X direction towards the elevator front plane 11 generates reflex images 14 which, due to the image distortion on the projection line 17 or on the CCD line image sensor 1.5, decrease in distance from Elevator front level 11 has a continuously increasing speed corresponding to the distortion function.
  • the detection system also has a distance-dependent sensitivity. To a lesser extent, this is also available for object movements in the Y direction.
  • an image resolution or sensitivity that increases progressively with decreasing distance from the elevator front plane 11 is achieved. This is desirable because the urgency of a quick door response increases progressively as the distance of a person approaching the entrance decreases.
  • the infrared light 3. 1 emitted by the infrared surface radiators 3 is directed in such a way that the floor of the anteroom surface 5 is not touched by the latter and so that there are no floor reflections due to unevenness, such as carpet edges, etc.
  • the horizontal radiation angle is preferably 120 ° each and the vertical radiation angle is 10 °, for example.
  • the floor call panel 24 shown can also have a numeric keypad for destination call control. With this device, the elevator control knows how many waiting people are on each floor. It is therefore not necessary to monitor the anteroom outside the cabin on every floor with appropriate facilities.
  • the infrared camera 1 above the elevator entrance 4 is inclined downward, for example, at an angle of 45 °, which also corresponds to the image recording angle.
  • the camera holder 2 is of great importance insofar as it is used to set a certain angle to the anteroom area 5, which is both directly determining the degree of distortion and has an influence on the size and position of the antechamber area 5 to be monitored. that no existing vertical surfaces, such as those of an opposite wall, come into the picture.
  • Objects located in infrared light 3.1 completely reflect infrared light 3.2 with correspondingly inclined surface parts and partly with all other more or less perpendicular surface parts facing infrared light 3.1.
  • a partial reflection of the infrared light 3.1 / 3.2 from more or less perpendicular surface parts of a person to the camera is possible because the smallest roughness of a surface causes scattering reflections and therefore the entire surface part of an object located in the infrared light 3.1 and facing it is clearly depicted in the camera becomes.
  • no other light hits the LCD microshutter 1.4, which means that only two image signals, infrared light or nothing, i.e. binary image data, are available right at the start of image processing.
  • the sensitivity to infrared light can therefore be set to a very small threshold value, the wavelength of the infrared area emitters 3 in particular emitted infrared light 3.1 or 3.2 is taken into account.
  • the control and evaluation can take place in a special control and evaluation unit 10 or be carried out by a processor system available for the elevator control.
  • a continuously operating learning algorithm stores object-typical contours and temporal changes in the taken reflex images 14 and supplies in the form of binary image data the basis for comparison for the generation of the logical command signals to the elevator control system.
  • the door control receives information about the intentions of the people 7 who are on the anteroom surface 5 at a certain moment on the basis of their number and behavior and reacts accordingly by holding them open for a long time, closing them prematurely or reversing. Most of the time, the door can be opened before an otherwise usual one Door hold-open times are closed prematurely, which means an increase in elevator capacity.
  • the device also works independently of the existing light sources in the area of the anteroom area 5 and its surroundings.
  • the antechamber can be illuminated by artificial light of any kind, daylight, sunlight or mixed light. Any reflections of infrared light in the sensitivity range of the camera 1 from artificial or natural light sources are at most perceived by the device, but are also recognized as such by the evaluation because they do not form object-typical reflex images 14 and are accordingly ignored. This is possible, among other things, because they come from light sources that send their light from a different direction than that from the infrared surface radiators 3.
  • two different images are taken in rotation, alternately one with infrared light 3.1 and one without infrared light 3.1.
  • those with infrared light 3.1 illumination are compared with those without infrared light 3.1 illumination and then the difference image data is passed on for further processing.
  • This procedure allows an even better distinction between desired and undesired picture elements and the pulsed operation of the infrared surface radiator 3 enables an increased intensity of the infrared light 3.1.
  • the device can also be installed on both sides of an entrance or passage gate, i.e. in a double version apply. In such an embodiment, it is possible to only let people in or just let them out through a corresponding influence on a door motor control. In this version, it can also be used for counting entering and / or leaving people.
  • the device described can also be installed in rail and road vehicles and also serves as an optimal door control. Another application relates to the registration of the behavior of people in a room or area to be monitored.
  • two or more systems of the type described can be installed next to one another, in addition to the side infrared surface radiators 3 and other infrared surface radiators 3 installed in a lower threshold or embedded in the floor.
  • the infrared surface heaters can be installed at any height.
