Definitions

  • the invention relates to a group control for elevators with double cabins with immediate assignment of destination calls, the double cabins being formed from two cabins arranged in a common car frame, into which a main stop can optionally be entered, with call registration devices arranged on the floors, which have a keyboard for the Have input of calls for desired target floors, with the call memories assigned to the elevators, which are connected to the call registration devices, with the input storey and a call identifying the destination floor being stored when a call is input, with load measuring devices provided in the upper and lower cabin of the double cabin , which are operatively connected to load stores, with the elevators assigned selectors, each denoting the floor of a possible stopping, and with a device by means of which the entered calls are allocated to the elevators , according to the preamble of claim 1.
  • CH-PS 529054 has disclosed a control system for an elevator group with double cabins, in which the double cabins are designed in such a way that two adjacent floors can be operated simultaneously.
  • the filling of a building should be achieved in the shortest possible time with approximately even occupancy of the double cabins by the fact that on the ground floor the passengers board the even-numbered upper floors in the upper cabin and the odd-numbered ones in the lower cabin, whereby the cabin callers for those not the Storeys assigned to the cabin are locked.
  • the lock is released so that the boarding person can travel to any floor.
  • Such lifts can carry twice as many passengers on each trip as lifts with single cabins. Since less has to be kept, the same number of floors can be served in a shorter time, so that the conveying capacity is increased considerably. With this control, however, it can happen that passengers who do not pay attention to the division of the even and odd floors into the upper or lower cabin do not have to reach the desired floor and have to get off at another. It must also be considered a disadvantage that the compulsory use of boarding passengers at the main stop is to use the correct cabin, not only during the relatively short period of peak traffic, but also during the rest of the time.
  • call registration devices with keys for entering calls for desired destination floors are arranged on the floors, whereas no call buttons are provided in the elevator cars.
  • call registration devices with buttons for even-numbered destination floors are arranged on the access for the upper cabins of the double cabins, while the entry for the lower cabins of the double-cabins has call registration devices with buttons for odd-numbered destination floors.
  • EP-A 0 356 731 discloses a group control described for individual cabins, which uses the shortest waiting time of all passengers as a criterion for the assignment of the cabins to the calls entered. With this control, the travel destinations can also be entered on the floors, for example by means of call registration and display devices proposed with EP-A 0 320 583.
  • a computer in the form of a microprocessor determines an amount for each cabin, based on elevator-specific data, which corresponds to the waiting time, which corresponds to the waiting time for the passengers to service the call would arise.
  • the operating costs are transferred to a cost register immediately after the calculation and then immediately compared with the operating costs of the other elevators by means of a comparison device.
  • an allocation instruction that has the lowest operating costs is stored in an allocation memory of the elevator.
  • the elevator and its location in question are displayed in a display field of the activated call registration and display device, so that the passenger can go to the assigned landing door in good time.
  • the invention has for its object to improve the control devices initially mentioned in the prior art in such a way that both elevators and lower cabins of the double cabins can be used for trips to even and odd floors in elevators with double cabins in the main station.
  • a call memory is assigned to the upper and lower cabin of a double cabin, in which the calls entered at the main station and identifying the destination floors are stored.
  • the circuit On the input side, the circuit is connected to the call memories in such a way that, depending on an assigned call, the double cabin in question is defined as holding on even-odd or odd-numbered floor pairs.
  • the circuit On the output side, the circuit is connected to the comparison device via a switching device, so that depending on a further call that is yet to be allocated, either the double cabins on odd-numbered floors or those on odd-numbered floor pairs cannot participate in the comparison and allocation process.
  • a call is assigned immediately after the entry, the elevator in question and its position being displayed on a display panel of the activated call registration device.
  • 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. The distance between the two cabins is chosen so that it matches the distance between two adjacent floors.
  • a main stop E0 provided, for example, on the ground floor has a lower entrance L1 to the lower cabin 5 and an upper entrance L2 to the upper cabin 6 of the double cabin 4, the upper entrance L2 being connected to the lower entrance L1 by an escalator 7.
  • the carrier 2 is controlled by a drive control known from EP-B 0 026 406, the setpoint generation, the control function and the start of the stop being implemented by means of a microcomputer system 8 which is connected to measuring and actuating elements 9 of the drive control.
  • the microcomputer system 8 also calculates, as is known, for example, from EP-A 0 356 731, from elevator-specific data a sum corresponding to the waiting time of all passengers, also called service costs, which is used as the basis for the call allocation process.
  • the cabins 5, 6 have load measuring devices 10, which are also connected to the microcomputer system 8.
  • Call registers known from EP-A 0 320 583 are on the floors Display devices 11 are provided, which have 10-keyboards, by means of which calls can be entered for trips to desired target floors.
  • the call registration and display devices 11 are connected to the microcomputer systems 8 via serial interface modules (not shown) and a serial data conductor 12.
  • the microcomputer systems 8 of the individual elevators in the group are connected to one another via a comparison device 13 known from EP-B 0 050 304 and a party line transmission system 14 known from EP-B 0 050 305.
  • the call memories 20, 21 and allocation memories 22, 23 have memory locations corresponding to the number of floors for each direction of travel, only the memories associated with the upward direction of travel being shown.
  • the call memories 20, 21 each consist of a first memory 20.1, 21.1 and a second memory 20.2, 21.2, the calls characterizing the storey storeys in the first memories 20.1, 21.2 and the calls characterizing the destination floors being stored in the second memories 20.2 .
  • 24 denotes an operating cost register intended for storing the operating costs.
  • a first selector 25 assigned to the lower car 5 and a second selector 26 assigned to the upper car 6 in the form of further registers form addresses corresponding to the floor numbers, by means of which the memory locations of the memories 20, 21 can be addressed.
  • the selectors 25, 26 each show the floor on which the double cabin 4 with the lower or upper cabin 5, 6 could still stop, for which purpose the second selector 26 for the first and the first selector 25 for the downward travel the second by one floor.
  • the call memory 20, 21 and the allocation memories 22, 23 are read-write memories which, like also registers 24, 25, 26, are connected to the bus 27 of the microcomputer system 8. The calls stored in the call memories 20, 21 according to example FIG.
  • Load values are stored in the load memory 28 per floor in the form of a number of people who are at a future stop or when passing a floor in the respective lower or upper cabin 5, 6, and which are calculated on the basis of the calls entered. In this case, load values formed from incorrect call inputs can be corrected by comparison with the values determined by the load measuring devices 10.
  • the door opening and closing times of the elevator concerned are stored in the door time memory 29 for each floor, while the journey times of the relevant double cabin 4 between a particular floor and every other floor are stored in the travel time memory 30.
  • the service cost register 24 is connected to the comparison device 13 via a switching device 31 in the form of tristate buffers, the activation connections of the tristate buffers being connected to the output of a circuit 32 described in more detail below.
  • the circuit 32 consists of an OR gate 33, which has six inputs, each of which is assigned to six successive floors. In a first execution according to 2, three of the inputs are each connected to outputs of the memory cells of the second memory 21.2 of the upper cabin 6 which are assigned to the odd-numbered floors, and the other three inputs are each connected to the outputs of the memory cells of the second memory 20.2 of the lower cabin 5 which are assigned to the even-numbered floors connected. In a second embodiment, however, as shown in FIG.
  • three of the inputs of the OR gate 33 are each connected to outputs of the memory cells of the second memory 21.2 of the upper cabin 6 assigned to the even floors, and the other three inputs are each connected to the Outputs of the memory cells assigned to the odd-numbered floors of the second memory 20.2 of the lower cabin 5 are connected.
  • the output of the OR gate 33 is connected to the activation connections of the tristate buffers.
  • the circuit 32 formed by the microcomputer system 8, for example on the basis of a program, is activated in each case when a call to be allocated is stored. Depending on the target floor in question and the memory in which the call was transmitted, either the connections according to the first or second embodiment are established in such a way that the target floor is assigned to the middle of three floor pairs defined by the circuit 32.
  • FIG. 4 only the second stores 20.2, 21.2 of the lower and the upper cab 5, 6 of the respective double cab 4 are shown for three elevators A, B and C of an elevator group.
  • the distribution of the destination calls entered on the lower or upper access L1, L2 (FIG. 1) and marked with "1" between the second memories 20.2, 21.2 is explained in more detail using an example in the following functional description.
  • the double cabin 4 of elevator A on even-odd-numbered floor pairs and the double cabin 4 of elevator B on odd-numbered floor pairs are located in the area of three adjacent floor pairs holding fixed, while the double cabin 4 of the elevator C is not yet fixed.
  • the address of the call input storey and that of the destination storey are transmitted to the microcomputer systems 8 of all elevators via the serial data conductor 12, only one call registration and display device 11 being able to access the serial data conductor 12 at a time.
  • the microprocessors of the microcomputer systems 8 interpret the address of the call input storey in such a way that the call pair in question is either only written into the call memory of the upper or only the lower cabins (example Fig. 2, L2 / E8). Now it is assumed, for example, that calls for the floors E8 and E7 are entered on the upper entrance L2 and calls for the floors E5 and E6 on the lower entrance L1.
  • switching device 31 is conductive. After the call for floor E8 has been entered on the upper access L2, the call is transferred to the call memories 21 of all the elevators assigned to the upper cabins 6, the circuit 32 being activated in accordance with the first embodiment in FIG. 2. Since the output of the memory cell assigned to the floor E8 is not connected to an input of the OR gate 33 and no call may yet be stored in the call memories 20, 21 of all elevators for the floors E5-E8, the switching device 31 remains in the conductive state so that all elevators can take part in the comparison. Now the operating costs for the new call pair are calculated for all elevators in accordance with EP-A 0 356 731 already mentioned.
  • the service costs are transferred to the service cost register 24 and to one another using the comparison device 13 proposed, for example, in accordance with EP-B 0 050 304 compared. It may be assumed that elevator A has the lowest operating costs, so that an allocation instruction is written into its allocation memory 23 on floors L2 and E8 (FIG. 2). The new call pair is then deleted from the lifts without any assignment instructions. With the allocation of the call for floor E8, the double car 4 of the elevator A is fixed in the area of three adjacent even-odd-numbered floor pairs, each holding the upper car 6 on even-numbered floors.
  • elevator B cannot take part in the allocation procedure, the call being allocated to elevator A, for example (FIG. 2).
  • the call for floor E6 also entered on the lower entrance L1 has the effect that elevator A is excluded from the allocation. According to the example, this call may be assigned to elevator B (FIG. 3).
  • the passenger is shown the assigned call and its location in a display field of the activated call registration and display device. If a destination call is stored for a floor pair either only for the lower or only for the upper cabin of a double cabin, the first selector is used for initiating the stop in the first case 25 and in the second case the second selector 26 is effective (FIG. 4, elevator A, E5 / E6, E7 / E8).
  • optical display devices can be provided which signal the more advantageous cabins to the newly arriving passengers depending on the destination calls already allocated.
  • information boards can be arranged on the entrances L1 and L2, on which it is displayed whether certain target floors can be reached more quickly by using lower or upper cabins 5, 6.
