Definitions

  • the invention relates to a device for controlling and securing a motor-driven wing of a door, a window or the like with detection means for detecting the wing and / or the area to be secured, for example the movement area of the wing, with evaluation means and with control means, preferably for controlling the motor drive of the wing, and the use of an image capturing device as capturing means, as well as a method for controlling and securing a motor-driven wing of a door, a window or the like with detection means for detecting the wing and / or the area to be secured, for example the movement area of the wing, with evaluation means and with control means, preferably for controlling the motorized drive of the wing .
  • Devices of this type for controlling and securing a door, a window or the like generally use a plurality of sensors, each of which detects and secures a specific door area for itself.
  • sensors which are designed either as motion detectors or as status detectors based on the reflection principle.
  • Motion detectors usually work according to the Doppler principle, ie a signal is emitted in a certain detection range and the reflected radiation is received. If there is a moving object, such as a person, in the detection area, the frequency of the reflected radiation will be greater or less than the frequency of the emitted radiation, depending on the direction of movement. This principle is independent of whether you work with infrared radiation, with radar or with ultrasound.
  • a few individual sensors are arranged on the upper edge of a motor-operated door leaf, which essentially emit their radiation downwards. These sensors work in the infrared range and react to changes in the amount of light reflected. If there are people or objects in the swivel range of the door leaf, the door drive can be stopped using the sensors.
  • DE 30 20 483 C2 describes a photoelectric device for scanning objects.
  • the arrangement of the individual sensors creates a quasi-zigzag pattern that allows a homogeneous and controlled scanning area to be recorded in depth.
  • a sensor of this type is mounted horizontally on both sides of a swing door, one device being used for opening and the other for securing.
  • Another known sensor arrangement which is commercially available has a housing which extends over the entire width of the wing in the manner of a grip strip and in which light-emitting and light-sensitive elements are arranged linearly next to one another.
  • DE GM 73 04 821 shows a safety device for sliding doors, which is used in particular for elevator doors. A pulse generator sends out pulses that are received by a corresponding receiver on the same door leaf. If the transmitted pulses are not properly received at the receiving device, it is assumed that there is a person or an object in the safety-relevant area, ie on the edge of the wing. Due to this fact, the door leaf's travel movement is switched off.
  • the object of the invention is a device for control and / or Protection of a motor-driven wing of a door, a window or to develop something that creates the possibility that all relevant Area of the door such as the proximity area, the fixed field, as well as the main and Secondary closing edge better detected and processes and conditions in the detected areas are recognized and a corresponding control of the the wing is driven by a motor.
  • the recording should be as possible simple means, inexpensive and versatile.
  • one or more image capture devices are used to capture the areas to be monitored.
  • the camera is connected to an evaluation unit, preferably to an IC or ⁇ P, which detects processes and conditions in the areas detected by the camera and initiates a corresponding control of the motor drive. This results in increased protection and the possibility of detecting malfunctions in the system.
  • Advantageous applications for escape route doors are possible.
  • the camera is intended to monitor a room in the area of an automatic door. For this purpose, a camera with the smallest possible camera head is used. It can be installed directly in the drive. It is also conceivable that two cameras are used.
  • the evaluation electronics can divide the monitored space into three different sections, in which reaction to movement or standstill must be responded to in a defined form. The setting of the sections should be done largely fully automatically.
  • the adaptation to the different environmental conditions, in particular to the constantly changing lighting conditions, must take place automatically. Constantly existing objects should be automatically removed from the monitoring.
  • the evaluation electronics should provide one, a maximum of two, digital signals at the output. Objects with dimensions of at least 30 qcm should be able to be detected. The resolution should be as low as possible. Color evaluation is not absolutely necessary.
  • the rooms to be monitored add up to an area of at least 4 m by 4 m.
  • the image capturing device is mounted in the door plane on the door frame or the wall above the door, the capturing direction being oriented vertically or almost vertically downwards.
  • Figure 1 shows a room on one wall 2 is a two-winged Sliding door system 1 with two door leaves 1a and 1b is located.
  • the sliding door leaves 1a, 1b are each on two upper rollers 3 in one above the door 1 located track 4a out.
  • the running rail 4a is mounted in a stationary manner on the wall 2 horizontal carrier 4 arranged.
  • an electric motor 5 is arranged on the carrier 4, which does not have one illustrated timing belt cooperates with the rollers 3.
  • the device according to the invention has an image capturing device 6, which for detecting and securing the door area 9 (Fig. 3) in the middle of the carrier 4 is installed above the door leaf 1a, 1b.
  • the detection direction of the optics 61 is directed vertically or almost vertically downwards, towards the floor.
  • the image capture device 6 is a CCD camera of conventional design, which are read out electronically can.
  • This image capture device 6 is connected to an evaluation unit 7a, which evaluates the data captured by the image capturing device 6 and accordingly acts on the control unit 7b.
  • the control unit 7b in turn controls the motor drive 5 of the door leaf 1a, 1b and thus the opening and Door closing movement 1.
  • FIG. 5 A block diagram relating to the above relationship is shown in FIG. 5. It shows the image capture device 6, which is connected to the evaluation unit 7a. From the evaluation unit 7a there is in turn a connection to the control unit 7b and from there to the motor drive 5. This offers advantages, for example, when an already existing door system 1 with an existing control unit 7b is to be retrofitted with the image acquisition 6 according to the invention including the evaluation unit 7a.
  • the evaluation unit 7a and the control unit 7b are preferably an IC or a microcomputer.
  • An alternative arrangement is shown in FIG. 6.
  • a combined control and evaluation unit 7 is provided, which combines the functions of the separate evaluation unit 7a and the control unit 7b in one IC or ⁇ C.
  • the image capture device 6 can also be arranged on the wing itself, in or on the running rail 4a, or in the Carrier 4 can be integrated. It is also conceivable for the image capture device (6) to be vertical to be arranged above or below the range of movement of the wings (1a, 1b), or even completely outside the range of motion, for example at a distance from the Wing level immediately before or after this. Especially if that Image capture device is arranged at a different point in the room than Above the wing (1a, 1b), the detection direction can be horizontal, diagonally be directed upwards or diagonally downwards towards the door. Preferably however is the optics 61 of the image capture 6 in the vertical or almost vertical direction directed up or down.
  • the image capturing device 6 has a two-part Optics 61, so that one part of the optics 61 the detection area 9 on the secures a door side and the second part of the optics 61 covers the detection area on the opposite side of the door (not shown). Per Door system 1 then only one image capture device 6 is required. As another Possibility can also the direction of detection of the image capture device 6 Reach through the wing level, both the side in front of the wing level and the side behind the wing plane is detected. This configuration is suitable especially for sliding door systems with glass leaves.
  • Figure 2 shows an embodiment which is installed on an automatic swing door 1. Shown is the partially opened rotary door 1a, which is articulated on its left vertical edge via two door hinges 11 on the door frame 12.
  • a motorized door drive 8 is arranged above the door leaf 1 a and has a conventional structure, as described, for example, in DE OS 32 02 930.
  • the drive housing 81 is mounted on the frame in the illustration in FIG. 2.
  • the output shaft 82 is coupled to a force-transmitting slide arm 83 which is guided in a slide rail 84 arranged on the wing.
  • the door opener 8 contains an electric drive motor 5 for opening and closing the door 1 as well as the evaluation unit 7a and a control unit 7b.
  • the statements relating to FIGS. 1, 5 and 6 apply accordingly to their functioning.
  • An image capturing device 6, preferably a CCD camera, is also mounted above the door 1. Their direction of detection is directed vertically or almost vertically downwards. A representation of the detection area secured in this way can be seen in FIG. 4.
  • An application is also on Revolving doors or arched doors possible, as well as basically on all motor-driven wings, such as on windows or the like.
  • Figure 3 shows a section along the floor level in Figure 1, from the Viewing direction of the image capture device 6.
  • The is shown in dashed lines Detection area 9 of the image capture device 6, which extends from the wall 2 extends semicircularly into the space in front of the door leaves 1a, 1b.
  • Detection area 9 of the image capture device 6 which extends from the wall 2 extends semicircularly into the space in front of the door leaves 1a, 1b.
  • the Geometry of the surface depending on the optics 61 of the image capture device 6 and does not necessarily have to be semicircular.
  • the only decisive factor is that the Detection area 9 areas in the vicinity of door 1, in particular in the Includes range of movement of the door leaf 1a, 1b, which was previously usually by several sensors were recorded individually and are now explained in more detail below will.
  • this is also advantageous detects when a person approaches door 1 from the side.
  • One person in this area is recognized by the evaluation unit 7a and depending on it Direction of movement initiated an opening or closing of the door 1.
  • the evaluation means 7a control initiate door 1.
  • This object size is determined by the evaluation unit 7a Difference to conventional motion detectors also recognized. Leaves it derive a safety function that the door opening then, for example does not fire when an infant or animal approaches the door.
  • the area of the main closing edge 92 is also affected by the Image capture device 6 captured and secured.

  • the evaluation unit 7a can the presence of a person in the area of the main closing edge 92 to everyone Recognize when. In contrast to the usual contact strips or Hollow profiles, it is not necessary here that the door closes first and on the Obstacle hits to recognize it. It will be at a very early stage Avoid closing the door when a person or object is in the Area of the main closing edge.
  • the fixed field 93 is the area which the door leaves 1a, 1b pass over when they open. Since a small gap remains between the wing 1a, 1b and the wall 2, there is a risk of objects or a hand being caught.
  • This area is also protected by the image capturing device 6 and the evaluation unit 7a gives the control unit 7b a signal which prevents the door from opening when a person or an object is in the area of the fixed field. Alternatively, it is also possible that the door only opens and then stops shortly before the obstacle is reached. The current position of the door leaves 1a, 1b is also detected by the evaluation unit 7a at any time. It would be conceivable to equip the evaluation unit 7a or the control unit 7b with an acoustic, optical or electrical warning signal which is triggered when a person is in the area of the main closing edge 92 or the fixed field 93 for a longer period of time and thus closes or Preventing door 1 from opening.

Furthermore, the evaluation unit 7a detects the respective position, speed and acceleration of the wings 1a, 1b using the image capture device 6 and transfers the determined values to the control unit 7b. Finally, the evaluation means can learn the door type and the range of movement of the leaves 1a, 1b, in particular their end positions, in a self-learning manner during commissioning. In addition, the evaluation unit 7a can be connected to a central alarm system, which is used for security monitoring of the door.
