Definitions

  • the invention relates to a device for controlling the distribution traffic in a main stop for elevator groups, with cabins accessible via automatically operable doors and a group control device which has control programs for the door operation and the upward peak traffic, on the floors call registration devices for the input of calls for desired destination floors are arranged.
  • Elevators with control programs for upward peak traffic are e.g. used in tall office buildings or other commercial buildings, the intention being to fill the building as soon as possible when starting work.
  • the cabins are provided in the main stop, which in this case is the ground floor, and are sent upwards at full load or at certain intervals. After the highest call has been dealt with, the cabins return to the main stop, depending on the control program, any downward calls that are present are fully, reduced or not served at all.
  • the control program for the upward peak traffic can be triggered here by means of traffic monitoring devices, as known for example from CH-PS 342 352.
  • call buttons are arranged in the cabins of the lifts described above, it is ensured that the passengers boarded in the main stop reach the destination floor entered.
  • US-A-3 374 864 a group control has become known, in which the desired destination floor is already on the Entry floor can be entered.
  • call buttons for all other floors are arranged on the floors, while no call buttons are provided in the cabin.
  • the control system which is designed for three floors and two elevators, works in such a way that the cabin intended for a destination floor announces the destination floor in the form of the floor number by an optical display device when it arrives on the entry floor, so that passengers who want to go to other destination floors do not get in wrongly.
  • a locking circuit is provided, which ensures that only the doors of an elevator can be opened in the presence of several cabins at the main stop, the calls entered at the main stop being assigned to this elevator.
  • the call registration devices are activated at a time dependent on the start of the door closing or blocked after entering a certain number of calls by means of a blocking circuit and released again when the relevant cabin leaves.
  • a display element which signals the blocking and is arranged in a display field of the call registration devices is activated.

  • the group control device which is similar, for example, to the group control device proposed by EP 0 032 213, operates in normal operation in such a way that newly arriving calls are allocated to those cabins that can service these calls in the shortest possible time.
  • the group control device also has a control program for the upward peak traffic, which runs in a manner similar to the prior art described above.
  • the calls entered in the main bus stop E0 are allocated to the cabin that arrives first or that already exists with open doors.

  • the latch circuit 28 consists of a first to seventh AND gate 38-44, each having two inputs, an eighth, AND gate 45 having three inputs, a first and second AND gate 46, 47 and an OR gate 48
  • the first, second and third AND gates 38-40 are assigned to the shaft doors 10 of the elevators a, b, c, the inputs of the first AND gate 38 with the door information transmitters 26 of the shaft doors 10 of the elevators b, c, the inputs of the second AND element 39 are connected to the door information transmitters 26 of the shaft doors 10 of the elevators a, c, and the inputs of the third AND element 40 are connected to the door information transmitters 26 of the shaft doors 10 of the elevators a, b.

  • the call registration device 4 has a display field 50, in which the call acknowledgment appears in the form of a decimal number when calls are input using the call buttons on the 10-key keyboard 51.
  • the decimal number can be represented, for example, by display electronics in the form of a seven-segment display with light-emitting diodes.
  • 52 is another display element which signals the blocking of the call registration device 4 in the form of an XX symbol, which is likewise formed by light-emitting diodes and which can be activated by means of the blocking circuit 25 and lights up red in the process.
  • the blocking circuit 25 and the locking circuit 28 are activated and the cabins are called to the main stop E0 by simulated floor calls. It may be assumed here that the car of elevator a first arrives at the main stop E0 and opens the doors. According to the logic chosen, for example, the relevant door information transmitter 26 generates a door information associated with the open state logically "0", so that the microcomputer systems 5 of the elevators b and c via the AND gates 39, 41 and 40, 45 start the Door control program preventing locking information is supplied logically "0" and a later arriving cabin of these elevators does not open the doors.
  • the door control program is now such that the opening of the doors is initiated shortly before entering the main stop E0. After the doors are fully opened, they are kept open for a certain time, after which they are automatically closed and the relevant cabin can be driven down. It is now assumed that the calls entered by the passengers at the main stop E0 have been acknowledged in the display fields 50 (FIG. 3) of the call registration devices 4, which means that they are allocated to an arriving or already existing cabin. As initially assumed, for example, the car of elevator a arrives at the main stop E0, wherein according to the selected logic, the selector signal, the stop signal and the upward travel signal are logic "1".
  • the AND gate 20 since the door information of the elevators b and c supplied to the AND gate 21 is logic "1", the AND gate 20, the AND gate 13 and 16 of the signaling circuit 11 and the first input e1 of the indicator 12 will first display element activated (Fig. 1).
  • the up arrow of the indicator 12 of the elevator a lights up green, which indicates to the waiting passengers that they can get in, since the calls they have entered and acknowledged are served by this elevator.
  • the call can only be entered up to a point in time before the start of the door closing.
  • a pulse is generated by the pulse generator 27 of the shaft door 10 of the elevator a, which is fed via the OR gates 34 and 33 to the set input S of the RS flip-flop 30.
  • the XX symbol 52 (FIG. 3) which signals the blocking of the call registration devices 4 is activated, so that it lights up red.
  • the transistor switch 31 is controlled in the open state, whereby the supply of the call buttons is interrupted and no more calls are acknowledged.
  • the registered calls are now transferred to the cabin call memory 7 of the microcomputer system 5 of the elevator a and then deleted in the call registration devices 4 (FIG. 1).
  • the door information of all elevators is logic "1", so that logic "1" is present at the output of AND gate 36. Since the assigned car position transmitter 24 signals a logic "1" until the car of the elevator a leaves, the output of the OR gate 35 is also logic "1", so that a short pulse occurs at the output of the AND gate 37 and the RS Flip-flop 30 is reset. As a result, its output Q is logically "0" and the blocking of the call registration devices 4 is released again.
  • the number of calls entered corresponds to the maximum permitted number of boarders before the time determined by the pulse generator 27.
  • a signal "1" occurs at the carry output o of the counter 29, by means of which the RS flip-flop 30 is set via the OR gate 33 and the blocking of the call registration devices 4 described in more detail above is triggered. Because of the signal propagation times, the blocking is triggered with a delay, so that the call of the last passenger is still acknowledged before the XX symbol 52 indicating the blocking appears in the display field 50 (FIG. 3).
  • the reset pulse occurring at the output of the AND gate 37 is also fed to the counter 29, so that it is reset.
  • the cabin of elevator b with open doors is on the main stop E0 and the cabin of elevator a arrives with a passenger who wants to get out at the main stop E0.
  • the microcomputer system 5 of elevator a logically ignores the locking information "0", so that the doors are opened and, after the passenger has exited, are closed again immediately.
  • the selector signal, the stop signal and the output of the memory cell of the car call memory 7 assigned to the main stop E0 are logic "1".
