Definitions

  • the invention relates to an elevator with shaft equipment and an information device comprising at least one reading unit and at least one coding for generating shaft information for moving an elevator car and / or a counterweight in the elevator shaft, wherein the arranged on the shaft equipment, readable by means of the reading unit encoding information for generating provides the shaft information.
  • the invention as characterized in claim 1, solves the problem of providing an information device that is easy and installable with little effort.
  • the advantages achieved by the invention are essentially to be seen in the fact that the information device can be mounted in a shorter time.
  • the elevator installer only needs to attach the reading unit to the elevator car.
  • the coding necessary for information generation is already arranged at the factory, for example on guide rails.
  • Other shaft equipment such as a cable channel extending over the shaft height, consisting of individual cable duct elements, or extended door frames are also suitable as code carriers.
  • the factory, each guide rail or each cable channel element or each extended door frame over its length provided with the above coding, the coding of each guide rail, each cable channel element or door frame is constructed comparable.
  • the coding maps the length, for example 0 meter to 5.00 meters, of the guide rail or of the cable duct element or of the door frame, wherein in addition each guide rail or each cable duct element or each door frame is provided with an individual identification.
  • the associated reading device and control can due to the identification of the order of the mounted guide rails or the cable channel elements or Detect door frame.
  • the guide rails or the cable channel elements or the door frames can be mounted in any order and in any orientation. When the information device is put into operation, the sequence and the orientation are recorded and stored with a learning run.
  • the elevator car moves up and down, wherein in each case the completely overridden guide rails are detected by means of the respective identification and the position of the elevator car and / or the counterweight is determined within the incomplete overrun guide rail by means of coding.
  • the absolute cabin position is then calculated from the length of the completely overrun guide rails and from the overtraveled length of the incompletely overrun guide rail.
  • the speed of the elevator car is important, for example, as an additional signal for the speed control in the acceleration, in the constant speed and in the deceleration. Also of importance is the speed of the elevator car in the initiation of measures at overspeed of the elevator car. At overspeed, for example, the engine is switched off and the engine brake triggered. If these measures do not lead to a reduction in speed, for example, a rail brake is triggered.
  • the above information device can also be used to measure the speed of the elevator car. Each cabin position is determined from the coding and the speed calculated from the distance traveled and the travel time required for it.
  • Fig. 1 schematically shows a plan view of an elevator car 1 movable in a lift cage 2 and an information device 4.
  • the elevator car 2 is guided along a rail track 3 forming guide rails, wherein in Fig. 1 only one rail track 3 is shown. Another rail track is arranged on the opposite side.
  • An information device 4 generates shaft information for controlling the car movement and the car position or the counterweight movement and the counterweight position.
  • the shaft information includes, for example, the speed and / or the position in the elevator shaft 1 of the elevator car 2 and / or a counterweight.
  • the Information device 4 consists in the illustrated embodiment of at least one reading unit 5 and at least one of a shaft equipment 9 arranged coding 6.
  • a redundant information device 4 is provided, with a coding 6 on the rail track 3, for example on the rail foot 7 a guide rail and another Coding 6 is arranged on the free leg 8 of the guide rail and each coding 6 is assigned a reading unit 5.
  • the information device does not have to be redundant.
  • only one coding 6 and only one reading unit 5 are provided.
  • the coding 6 can also, as mentioned above, be arranged at another shaft equipment 9, such as at a cable channel extending over the shaft height, consisting of individual cable channel elements, or as mentioned above, for example, on extended door frames.
  • Fig. 2 schematically shows an arranged on a shaft equipment 9 coding 6 with two-dimensional code patterns 2D.
  • Each code pattern consists of a checkered array of fields, each field being black or white depending on the information content of the code pattern.
  • the checkered arrangement of the fields is similar to a checkered sheet of paper, in which each house can be filled in black or empty.
  • the reading unit 5 can recognize the image of black and white fields and determine the information content therefrom.
  • a first code pattern on the shaft equipment 9 is denoted by a 1 , for example the lowest code pattern of a guide rail 3.1
  • a second last code pattern is denoted by a n-1 , for example a second-highest code pattern of the guide rail 3.1
  • a last code pattern is attached to denotes, for example, a top code pattern of the guide rail 3.1.
  • the code patterns a 1 to are different because each code pattern has a different information content.
  • the code patterns between the lowest code pattern a 1 and the uppermost code pattern are arranged at a certain distance DS to the adjacent code pattern on the guide rail 3.1 and contain at least one piece of information about the respective position of the code pattern a 1 ... within the guide rail 3.1 or included a readable scale across the length in code form.
  • the information on the position of the code pattern can also be contained twice in each code pattern a 1 ..., once for the travel of the elevator car 2 upwards and once for the travel of the elevator car 2 downwards.
  • the guide rail 3.1 can be mounted with the first code pattern a 1 down or up.
  • At least the information ID for identification of the guide rail 3.1 can optionally be contained in all code patterns a 1 ...
  • the information device 4 the information ID for identification of the guide rail 3.1 and the relative Read or determine position immediately.
  • the information ID for identifying the guide rail 3.1 and the information for determining the relative position within a guide rail or other information may also be stored in a code.
  • the reading device 5 reads the code and the information device 4 further processes the different information one by one.
  • the total length of the guide rail 3.1 can be determined without code pattern at the rail 3.11. If the guide rail 3.1 stretches, the distance DS between the adjacent code patterns a 1 ... Changes or increases. Length errors due to elongation of the guide rail 3.1 are minimal and usually need not be corrected. Occasionally, however, a further learning run can be carried out by means of which the determined shaft positions are assigned to the door positions.
  • Fig. 3 shows an embodiment of a coding 6 with one-dimensional code patterns 1D. Each code pattern consists of a readable bar code. The comments on the code patterns of Fig. 2 also apply to the code patterns of Fig. 3 ,
  • each guide rail or cable duct element or extended door frame is provided with the above coding along its length, each guide rail having its own identification and its own, readable scale throughout its length and each cable channel element in the coding being its own Identification and its own, readable scale across its length or each door frame in its coding has its own identification and its own, readable scale across its length.
  • the coding 6 may for example be arranged as a band on the shaft equipment 9 or embossed on the shaft equipment 9 or stamped or lasered or nailed.
  • Fig. 4 shows an example for determining the position of the elevator car 2 and / or the counterweight in the elevator shaft 1.
  • the first guide rail 3.1 is connected to the second guide rail 3.2 and the second guide rail is connected to the third guide rail 3.3.
  • the distance between the last coding of a guide rail and the first coding of the other guide rail is known by the distance AS.
  • the information device 4 After mounting the factory-coded guide rails 3.1 ... 3.3 performs the elevator car 2 in the elevator shaft 1 through a learning trip.
  • the information device 4 stores the information readable by means of the at least one reading unit 5 from the coding 6.
  • the stored information is an image of the information contained in each code pattern. If, for example, a code pattern can not be read in when driving over because of damage or contamination from the reading unit 5, the missing information is replaced by the stored information and, for example, an error message or a maintenance message is issued.
  • the elevator car 2 moves with or without passengers from the bottom floor up.
  • the information device 4 knows the destination and the direction of travel. From a learning journey, the information device 4 also knows the individual guide rails 3.1... 3.3 due to their coding 6 and thus also the complete rail track 3. 3. 3. 3.3.
  • the information device 4 knows the first guide rail at the given travel destination 3.1 and the second guide rail 3.2 complete and the third guide rail 3.3 are only partially run over. While driving, only the identification of the first guide rail 3.1 and the identification of the second guide rail 3.2 are read. When driving over the third guide rail 3.3, each code pattern a 1 ... is read.
  • the above information device 4 can also be used to measure the speed of the elevator car 2.
  • the car position is determined at each code pattern a 1 ... on the rail track 3 and the speed calculated from the distance traveled and the travel time required for it.
