Definitions

  • the invention relates to a device for generating shaft information in an elevator, wherein an elevator car is connected to a position transmitter, by means of which positions of the elevator car that match at least certain shaft locations can be determined.
  • a memory is also provided, in which the location numbers identifying the specific shaft locations are stored.
  • a coded floor number transmitter and a corresponding code reader are installed on each landing on each landing door. In the event of asynchronism or data loss with a cabin on the floor, this facility reads in the floor number from the shaft door horizontally moving past the code reader.
  • the invention has for its object to provide a device of the type mentioned, the design effort is largely independent of the number of shaft information and floors and in which fewer shaft installations and fewer conductors are required in the hanging cable compared to the prior art.
  • a transmission element which transmits the elevator movements without slippage through a positive fit via the drive pulley to a pulse generator in the machine room.
  • a memory is provided in which, in a known manner, certain chimney locations are stored, which are successively transferred to a register in the course of a journey depending on the direction of travel.
  • the position transmitter has a counter, in which corresponding location numbers are formed during the journey of the respective position of the elevator car.
  • the register and the counter are connected to a comparator which, as usual, compares the local numbers. If they are identical, a signal representing shaft information is generated and a switching element assigned to the relevant shaft location is activated.
  • FIG. 1 denotes an elevator shaft in which an elevator car 4 driven by a conveyor machine 2 via a conveyor cable 3 is guided.
  • a pulse generator 5 in the form of a digital tachometer is coupled to a drive pulley 6 which can be driven by means of a belt 8 fastened to the elevator car 4 and guided over a deflection roller 7 arranged at the lower end of the shaft.
  • the torque is transmitted to the drive pulley 6 by means of a positive fit, which can be produced, for example, through holes provided in the band 8, into which teeth arranged on the drive pulley 6 engage.
  • the pulse generator 5 and a counter 9 form a position transmitter, the pulse generator 5 generating a pulse, for example, per 1 mm of travel of the elevator car 4, and the pulses in the counter 9 are summed up to local numbers which correspond to the respective car position and are based on a specific basis, for example cover the floor of the car when the elevator car 4 is in the lowest stop.
  • KUET, KSE1, KSE2 and KSE3 denote contacts of a safety circuit which can be actuated by means of switching elements 10, 11, 12, 13, for example in the form of relays, when the elevator car 4 drives past certain shaft locations.
  • the one contact is KUET a door bridging contact to be switched in the door area during travel and the other contacts KSE1, KSE2 and KSE3 shaft end contacts, by means of which the delay of the elevator car 4 when entering a final stop can be controlled.
  • the particular chute locations are identified by location numbers which are stored in a memory 14 which is connected to a register 15.
  • the register 15 and the counter 9 of the position transmitter are connected to a comparator 16, the register 15 and the counter 9 being the registers of a microprocessor 17, the arithmetic unit of which forms the comparator 16.
  • the memory 14 in the form of a read-write memory, the microprocessor 17 and a read-only memory 18 are connected to one another via a bus 19 and, together with a clock generator 20, form a microcomputer 21.
  • An address decoder 22 is connected to the inputs on the bus 19 and with an output a bus driver 23 connected.
  • the bus driver 23 is connected on the input side to the pulse generator 5 and on the output side to a data conductor of the bus 19.
  • Further outputs of the address decoder 22 are connected to further bus drivers 24, 25, 26 and 27, which are connected on the output side to the Realis 10, 11, 12 and 13.
  • the microcomputer 21 and the pulse generator 5 are connected to a buffered supply 28 connected to a three-phase network RSTO, so that the operation of the device is ensured in the event of a mains voltage failure and no data loss occurs.
  • the pulse generator 5 is set in synchronous motion by the belt 8 via the drive pulley 6 and the bus driver 23 is activated with the aid of the address decoder 22, so that the pulses generated by the pulse generator 5 are transmitted and summed up to local numbers in the counter 9 can.
  • the location number of the particular shaft location closest to the starting location of the elevator car 4 in the direction of travel is then transferred from the memory 14 into the register 15.
  • the location numbers of the counter 9 and the register 15 are now continuously compared with one another in the comparator 16.
  • the address of the location number of the relevant shaft location is decoded in the address decoder 22 and the assigned bus driver is activated, whereupon the downstream relay is excited and its contact is actuated. Thereafter, the location number of the next determined shaft location closest in the direction of travel is transferred to the register 15 and continued in the manner described above.
