Definitions

  • the invention relates to a group control for elevators with double cars, which are formed from two cars arranged one above the other in a common car frame, with car call memories and load measuring devices assigned to the cars, with floor call memories, with each elevator assigned to the group, each indicating the floor of a possible stopping as well as with a scanning device having at least one position for each floor, a control device being provided by means of which the double cabins of the elevator group can be allocated to the floor calls.
  • Such lifts can carry twice as many passengers on each trip as lifts with single cabins. Since less has to be held, the same number of floor calls can be serviced in a shorter time, so that the conveying capacity can be increased considerably.
  • the control of the elevator group works according to the system of dividing the travel path into zones, with cars and zones being assigned to one another and the cars being distributed over the entire travel path according to the position of the zones.
  • the allocation of the floor calls to the cars is only dependent on the position and direction of the calls, whereas other factors, such as the car load, are practically not taken into account in the allocation procedure.
  • a uniform distribution of the passengers to the individual cabins of the double cabins is therefore not possible during normal operation of the elevator system, so that optimal results cannot be achieved in relation to short average waiting times of the passengers and increase in the conveying capacity.
  • the assignments of the cabins to the floor calls can be optimized in terms of time.
  • a computing device in the form of a microprocessor, during a scanning cycle of a first scanner on each floor, whether there is a floor call or not, the distance between the floor and the car position indicated by a selector, the intermediate stops to be expected within this distance and the instantaneous cabin load is calculated as a sum proportional to the time lost by waiting passengers and the time lost by passengers in the cabin.
  • the cabin load at the time of the calculation is corrected in such a way that the expected boarding and disembarking operations, derived from the number of boarding and disembarking passengers in the past, are taken into account in future stops.
  • This total loss time also called operating costs, is stored in a cost memory.
  • an allocation instruction which designates the floor to which the relevant car is optimally assigned in time can be stored in an allocation memory of the elevator with the lowest operating costs.
  • the object on which the invention is based is to provide, by improving the group control described above, a group control for elevators with double cabins, by means of which the double cabins can be allocated to the floor calls in such a way that minimal average waiting times of the passengers are achieved and the conveying capacity is increased.
  • the invention proposes, with the features characterized in the independent claim, to calculate the operating costs for each of the two cabins of a double cabin and to compare them with one another by means of a comparison circuit, the lower operating costs being stored in the cost memory of the elevator in question and being present Allocation instructions for rectified floor calls of two adjacent floors and / or coincidences of car calls and scanner positions reduce the service costs to be saved.
  • the advantages achieved by the invention are, in particular, that stopping on adjacent floors with rectified floor calls and / or on floors with cabin and floor calls is promoted, as a result of which fewer stops occur, waiting times are reduced and the conveying capacity is increased.
  • Another advantage is that the cab serves a single floor call with the lower operating costs. To this In this way, the double cabins are filled more evenly and the delivery rate is increased.
  • 1, 1 denotes an elevator shaft of an elevator a of an elevator group consisting of, for example, three elevators a, b and c.
  • a conveyor machine 2 drives, via a conveyor cable 3, a double cabin 4, which is guided in the elevator shaft 1 and is formed from two cabins 5, 6 arranged in a common car frame, sixteen floors E1 to E16 being operated according to the elevator system chosen as an example.

  • R3 denotes a selector in the form of a further register which, when the car is moving, displays the address of the floor on which the car could still stop.
  • the selector addresses are assigned target paths which are compared with a target path generated in a setpoint generator. If the paths are identical and a stop command is present, the delay phase is initiated. If there is no stop command, the selector R3 is switched to the next floor.

  • the comparison circuit VS required for the operations described in more detail below is formed by the microprocessor CPU.
  • microcomputer systems 7 of the individual elevators a, b, c are connected to one another via a comparison device 14 known from European patent application No. 0050304 and a third interface IF3 and via a partyline transmission system 15 and a fourth interface IF4 known from European patent application No. 0050305 connected and in this way form the group control according to the invention.
  • the first scanner R1 assigned to the elevator concerned begins with one cycle, hereinafter referred to as the cost calculation cycle KBZ from the selector position in the direction of travel of the cabin, whereby the event may have occurred at elevator a (time I).
  • the microprocessor CPU of the microcomputer system 7 With each scanning position, the microprocessor CPU of the microcomputer system 7 now calculates for each individual cabin 5, 6 of the double cabin 4, in accordance with the formulas of claims 2 and 3, a sum proportional to the time lost by waiting passengers, also called operating costs K, the factors k, and k 2 as in one with European Patent Application No.
  • the total operating costs K " , K h then formed for each individual cabin 5, 6 of the double cabin 4 by means of the adders AD1, AD2 of the comparison circuit VS are compared with one another, and an identifier of the cabin 5 or 6 with the lower operating costs is stored in the identifier memory RAM11
