Definitions

  • the invention relates to a group control for elevators with double cars, which are formed from two cars arranged in a common car frame, with car call memories and the 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, and 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 the passengers have short average waiting times and increasing the delivery rate, optimal results cannot be achieved.
  • 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 momentary 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.
  • a cost comparison cycle by means of a second scanner are compared with the operating costs of all lifts over the comparison means with each other, each in a Z uillers Grande of the elevator with the lowest operating costs of a Zuillersanwei Solution can be stored, which designates the floor to which the cabin in question is optimally assigned in terms of time.
  • 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 claims, 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 with If there are allocation instructions for rectified floor calls from two adjacent floors and / or coincidences between car calls and scanner positions, the operating costs to be saved are reduced.
  • the advantages achieved with 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, which means fewer stops, shorter waiting times and increased conveying capacity.
  • Another advantage is that the cab serves a single floor call with the lower operating costs. 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 a conveyor cable 3 in the elevator shaft 1 guided double car 4, formed from two cars 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 5, 6 is selected so that it corresponds to the distance between two adjacent floors.
  • the carrier 2 is controlled by a drive control known from the European patent application No.
  • 0026406 the setpoint generation, the control functions and the initiation of the stop being implemented by means of a microcomputer system 7, and with 8 the measuring and actuating elements of the drive control, which are symbolized by a first interface IF1 are connected to the microcomputer system 7.
  • Each cabin 5, 6 of the double cabin 4 has a load measuring device 9, a device 10 signaling the respective operating state Z of the cabin and cabin call transmitter 11.
  • the devices 9, 10 are connected to the microcomputer system 7 via the first interface IF1.
  • the car call transmitter 11 and the floor call transmitter 12 provided on the floors are connected to the microcomputer system 7, for example, via an input device 13 which has become known with European patent application No. 0062141 and a second interface IF2.
  • the microcomputer system 7 consists of a storey call memory RAM1, two of the individual cabins 5, 6 of the double 4 assigned car call memories RAM2, RAM3, one load memory RAM4 storing the current load P m of each individual car 5, 6, two memories RAM5, RAM6 storing the operating state Z of the cars 5, 6, two cost share memories RAM7, RAM8, one cost memory RAM9, one Allocation memory RAM10, a license memory RAM11 storing an identifier of the cabin 5, 6 with the lower service costs K, a program memory EPROM and a microprocessor CPU which is connected via a bus B to the memories RAM1 to RAM11, EPROM.
  • R1 and R2 denote a first and a second scanner of a scanner, the scanner R1, R2 being registers by means of which addresses corresponding to the floor numbers and the direction of travel are formed.
  • the cost share memory RAM7, RAM8 have two memory locations v, h for each scanning position, which are assigned to the two cabins 5, 6 of the double cabin 4.
  • 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.
  • a comparison circuit VS linked to the cost share memories RAM7, RAM8, the cost memory RAM9 and the identification memory RAM11 has, according to FIG. 2, two adders AD1, AD2 and a comparator KO.
  • 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 as well as 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 second sampler R2 After completion of the cost calculation cycle KBZ (time II) the second sampler R2 start at all lifts a, b, c at the same time one rotation, hereinafter referred to as K east CPC comparison cycle, starting from the first floor (time III).
  • K east CPC comparison cycle For example, the KVZ cost comparison cycles start five to ten times per second.
  • the operating costs K or K h contained in the cost memories RAM9 of the elevators a, b, c are fed to the comparison device 14 and compared with one another, wherein an allocation instruction in each case in the allocation memory RAM10 of the elevator a, b, c with the lowest operating costs K.
  • Form of a logical "1" can be stored, which designates the floor to which the elevator a, b, c in question is optimally assigned in time. For example, based on the comparison in the scanning position 9, a reassignment may take place by deleting an assignment instruction for elevator b and enrolling one for elevator a (FIG. 1). Since, according to the example for floor E9, a floor call is stored and the selector R3 points to this floor (FIG. 1), the delay phase could be initiated for elevator a if the criteria mentioned at the beginning were given.
  • the indicator "1" is present in the Indicator memory RAM11 predefines the destination path corresponding to the next selector position, so that the double cabin 4 would hold, for example, with the less loaded rear cabin 5 or 6 on floor E9.
  • a new cost calculation cycle KBZ is started for elevators a and b, and cost comparison cycle 5 is interrupted because the former has priority. While the cost calculation cycle KBZ of elevator b runs without interruption, that of elevator a may be suspended between times IV and V due to a drive control process.
  • the cost comparison is then continued from scanner position 10 in order to be interrupted again at scanner position 9 (downward) by the occurrence of an event in elevator c, for example a change in the selector position (time VI).
