Definitions

  • the invention relates to an absolute position measuring system for a revolving door for determining a path position of running on a circumference Wing.
  • the measuring system according to the invention is therefore with a in or on a rail extending on or on the circumference located Code band indicating an absolute position, in or on arranged on the wing (s) optical scanning system, which is the Code tape scans, and equipped with a decoder based on of a signal output by the optical scanning system is absolute Position of the wing (s) determined.
  • This will be a special Flexibility created because each position of each wing determined at any time without having to do a zero point indexing or provide other mechanical aids in addition to the measuring system.
  • the code band is not only has dashes at a certain distance in the process the wing lead to emitted by the sensor pulses, but indicates an absolute position, even after a power outage directly can be read and evaluated.
  • the code band is not only has dashes at a certain distance in the process the wing lead to emitted by the sensor pulses, but indicates an absolute position, even after a power outage directly can be read and evaluated.
  • only one wing is mentioned Understandably, revolving doors are always one Plurality of wings.
  • the decoder is preferably arranged in or on the wing.
  • This to the alternative embodiment of the arrangement of Decoders in a stationary, z. B. in a control unit arranged Decoder has the advantage that the signals output from the sensor not for B. on the rail, along which moves the wing transferred but an evaluation of the on or in itself moving wings generated sensor signal directly on or in the wing can be done. Now only a transmission of the evaluated absolute position to a stationary control required, however because of the simpler signal relative to the sensor output signal can also be transmitted more easily.
  • the code tape is preferably made of a self-adhesive strip.
  • the optical scanning system can for this purpose preferably together attached to the wing with the decoder as a unit and over the wing be powered.
  • the signals output by the decoder can then z. B. modulated on the power line or an additional Data rail to be transmitted to the stationary control and the otherwise difficult to assemble and adjust code strip can simply glued along the rail or on the rail become.
  • the code band preferably extends over the entire length of the rail. These are not just specific areas the rail, but the entire travel of the wings in terms of their absolute position detectable.
  • the code band contains continuous characters or character combinations.
  • In this embodiment is also an absolute position indicated by the code band easily identifiable for people without additional resources.
  • the characters or character combinations repeat over the length of the code tape not, so that of the code tape one absolute position unique and without evaluation of multiple characters or Character combinations is displayed. This means that the characters or character combinations only once over the entire length of the Rail are available.
  • the measuring system according to the invention can be used as an optical scanning system Include CCD camera.
  • this CCD camera can a in the first preferred embodiment described above the code band consecutive character combination easily detected and by a corresponding processing will be evaluated.
  • it is z. B.
  • the code tape from a self-adhesive tape measure exists that evaluated via an image capture using the CCD camera becomes.
  • At least one code band is preferred Adjustment strip provided.
  • an alignment strip can contiguous characters or character combinations provided on the code tape or other absolute position indicating elements more easily be identified because their relative position to the alignment strip is known.
  • the Code band on a binary code the further preferably a Gray code is.
  • the binary code is preferably dark stripes on a light background or non-reflective strips built on a reflective ground.
  • the binary code preferably from a bar of a certain point width, the farther is preferably arranged between two alignment strips.
  • the optical scanning system in this second invention Embodiment preferably a line sensor and more preferably an illumination source for illuminating the code band.
  • an optical low-cost linear sensor can be used according to the invention be, for each recording z. B. with a vertical bar z. B. reads 100 pixels and passes this data to a processor, from which determines the position.
  • FIG. 1 An exemplary embodiment of a measuring system is shown in FIG. 1 played.
  • Measuring system for the absolute measurement of the sash stands on one Circumference, on which the wings move, be applied. So It is also understandable that after a power outage the driven Wing over the turnstile do not need to perform a first learning trip, because due to the measuring system an absolute position of the wings at any time along the circumference can be determined.
  • FIG. 1 shows a schematic enlarged view of a measuring system. It is on or in a raceway (circumference) of the wings a code tape 5 arranged, which of the scanning system 6 on the wing is scanned.
  • the scanning system 6 consists of an optical lens 6b and an optical sensor 6a and is for transmitting data 15 with a decoder 7 connected to the z.
  • B. a signal processor for decoding the absolute position over hard-coded patterns or continuous ones Bar code can be.
  • the scanning system 6 receives a supply voltage 14 from a power supply / data exchange unit 10, disposed within the wing and with conductors 1, 2 is connected to these to those given by a control unit 8 Supply voltage 14 to be connected to the control unit 8 data 15 exchange.
  • the decoder 7 receives its supply voltage 14 also from a power supply / data exchange unit 10.
  • the trained here as a signal processor decoder 7th is connected to the controller 8 for the purpose of data exchange.
  • the code tape 5 is preferably made of a self-adhesive Strip containing continuous characters, such as numbers and / or letters, and which is mounted along the entire length of the trajectory.
  • the Character combinations are preferably not repeated.
  • FIG. 2 shows an alternative embodiment of the code tape 5, for which can be used as a sensor 6a a linear sensor, which is a binary code 5b scans the formed position information of the code tape 5.
  • the lens 6b z. B. be a Plexiglas optics that the code image centered on the sensor surface and achieved a certain focus, even at fluctuating distance of at least the sensor 6a and 6b carrying the reading head to the code tape 5 an exact Evaluation of the data allows.
  • Such a plastic optics can z. B. be clipped onto the linear sensor 6a.
  • the decoder 7 directly with the as a linear sensor trained sensor 6a connected.
  • the second preferred embodiment according to the invention shown in FIG is with respect to the first embodiment described above, which contains a CCD camera, cheaper, since a usable here optical low-cost linear sensor, z.
  • the code band 5 consists of a binary code, the z. With black Strip is constructed on a white background. As a relatively fault tolerant thereby the Gray code proved, in which pro progressive Value changes only 1 bit.
  • the code band 5 is preferably connected by means of a pair (not shown). Illuminated IR diodes, so anytime a defined amount of light on the Sensor is reflected. On both sides of the code, eg. B. under and above the code, alignment strips 5a are applied, the width and Distance allows accurate location of each bit.
  • the read-in data words are reduced to their minimum values from both sides examined to find the alignment strip 5a. This will at the same time the distance of the alignment strip 5a as a read pixel value and the remaining pixels detected can be determined by the number of bits used for encoding are shared, one at a time Determine bit associated pixels. The bit pixels become the two or four middle weighted and decrypts the corresponding bit from it.
  • the position word is z. B. via a data rail or z. B. modulated transmitted on the conductors 1, 2 to the controller 8.
