Definitions

  • the invention relates to a group control for elevators with immediate assignment of destination calls, with call registration devices arranged on the floors, by means of which calls for desired destination floors can be entered, with the storeys and car call store memories assigned to the elevators, which are connected to the call registration devices, in which case Input of calls on a floor a call characterizing the input floor is stored in the floor call memory and the calls characterizing the target floors are stored in the car call memory, and with load measuring devices provided in the cars of the elevator group, with each elevator assigned to the group, each indicating the floor of a possible stopping Selectors, assigned to each elevator of the group, having at least one position for each floor and having a device by means of which the calls entered enter the cars d he elevator group can be allocated, according to the preamble of claim 1.
  • the car call memory of an elevator of this group control consists of a first memory which already contains allocated car calls and further memories assigned to the floors, in which the calls which have been entered on the relevant floors for desired destination floors and have not yet been allocated to a car are stored.
  • a device by means of which the entered calls are allocated to the cabins of the elevator group has a computer in the form of a microprocessor and one Comparison device.
  • the computer calculates the time lost by waiting passengers from at least the distance between the floor and the cabin position indicated by a selector, the intermediate stops to be expected within this distance and the load in the cabin Total proportional to the floors and in the cabin. If the first scanner encounters an as yet unallocated floor call, then the calls entered on this floor for the desired destination floors and stored in the further memories of the cabin call memory must also be taken into account. An additional sum proportional to the time lost by the passengers in the cabin is therefore determined and a total sum is formed. This total, also called operating costs, is stored in a cost memory.
  • the operating costs of all elevators are compared with one another by means of the comparison device, an allocation instruction being stored in an allocation memory of the elevator with the lowest operating costs, which indicates the floor to which the relevant car is optimally assigned in terms of time.
  • the service costs are calculated immediately after the entry of a call for a desired destination floor, the subsequent assignment of the call to the cabin with the cheapest service costs being carried out by means of the subsequent comparison.
  • a call assigned to a particular car for the first time can be assigned to another car if it has not yet been transferred to the drive control of the elevator in question. This allows passengers waiting for a cabin on one floor Difficulties arise because it is not possible to signal the ultimately allocated cabin in good time.
  • the advantages achieved by the invention are that the relevant cabin can be signaled immediately after the first assignment of a call, so that there is sufficient time for the passengers waiting on one floor to recognize the display and to go to the signaled elevator in good time.
  • a and B designate two elevators of an elevator group, with each elevator driving a car 2 guided in an elevator shaft 1 by a conveyor 3 via a conveyor cable 4 and serving thirteen floors E0 to E12.
  • the carrier 2 is controlled by a drive control known from EP-B-0 026 406, the setpoint generation, the control functions and the start of the stop being implemented by means of a microcomputer system 5 which is connected to measuring and actuating elements 6 of the drive control.
  • the microcomputer system 5 also calculates from elevator-specific parameters a sum corresponding to the average waiting time of all passengers, also called service costs, which is used as the basis for the call allocation process.
  • the cabin 2 has a load measuring device 7, which is also connected to the microcomputer system 5.
  • Call registering devices 8 in the form of 10-keyboards are provided on the floors, by means of which calls can be entered for trips to the desired destination floors.
  • the call registration devices 8 are connected via an address bus AB and a data input conductor CRUIN to the microcomputer system 5 and to an input device 9 which has become known from EP-B-0 062 141.
  • the call registration devices 8 can be assigned to more than one elevator of the group, wherein, for example, those of the elevator A are connected to the microcomputer system 5 and the input device 9 of the elevator B via coupling links in the form of multiplexers 10.
  • the microcomputer systems 5 of the individual elevators in the group are connected to one another via a comparison device 11 known from EP-B-0 050 304 and a party line transmission system 12 known from EP-B-0 050 305 and form together with the call registration and input devices 8, 9 in this way a group control which structurally corresponds to a group control described in EP-A-0 246 395.
  • the microcomputer system 5 shown partially schematically in FIG. 2 has a floor call memory RAM1, a car call memory RAM2, a cost memory RAM4, an allocation memory RAM5, a first and second scanner R1 and R2 and a selector R3 on.
  • the car call memory RAM2 consists of a first memory RAM2 ', which has memory locations corresponding to the number of floors, in which calls which have already been allocated are stored.
  • the car call memory RAM2 also has further memories RAM2.0, RAM2.1 Vietnamese RAM2.12 assigned to the floors E0, E1 .... E12, which also have memory locations corresponding to the number of floors into which the calls entered into the relevant floors are transmitted which have not yet been assigned to a specific car.
  • the self-holding circuit 13 consists of a first, second, third and fourth AND gate 14, 15, 16 and 17 each having two inputs, a first OR gate 18 having two inputs, and a second, three inputs having OR gate 19 and two NOT gates 20 and 21.
  • 22 and 23 designate memory cells of the allocation memory RAM5 and the storey call memory RAM1, whose clock connections C, as is known, are connected via AND gates 24, 25 to write and address connections we, a are, the address port a with the second Scanner R2 (Fig.2) is linked.
  • the data outputs Q of the memory cells 22, 23 are connected via the NOT gates 20, 21 to the inputs of the first AND gate 14, the output of which via the one input of the first OR gate 18 to the data input D of the memory cell 22 of the allocation memory RAM5 and via one input of the second OR gate 19 is connected to the data input D of the memory cell 23 of the storey call memory RAM1.
  • the data output Q the memory cell 23 is also connected via the NOT gate 21 to one input of the fourth AND gate 17, the output of which is connected to the other input of the first OR gate 18.
  • the other inputs of the second and fourth AND elements 15 and 17 are supplied with an assignment instruction Co which can be generated during a comparison process in accordance with the aforementioned EP-B-0 050 304.
  • the output of the first AND gate 14 is also connected to one input of the third AND gate 16, the other input a 'of which is connected to the selector R3 (FIG. 2) and the output of which is connected to the drive control of the elevator in question.
  • the self-holding circuit 13 can be formed by the microprocessor of the microcomputer system 5 on the basis of a program at each position of the second scanner R2 (FIG. 2) for the floor in question.
  • a floor call for floor E5 is stored in the floor call memory RAM1 and the calls for the destination floors E7 and E9 are stored in the further memory RAM2.5. It may now be assumed that in the first comparison after the call input, the floor call E5 is assigned to the elevator A, the calls E7 and E9 stored in the further memory RAM2.5 being evident from the aforementioned EP-A-0 246 395 the first memory RAM2 'of the car call memory RAM2 are transferred.
