Definitions

  • the invention relates to a method and system for modernizing an elevator system according to the definition of the preambles of the independent claims.
  • Elevators for the transport of persons / goods are relatively durable capital goods with lifetimes of 20 years and more. If after such a long time a major overhaul of an elevator system is pending, the components of the elevator system are technologically often obsolete, which makes a more or less complete replacement of the components necessary, which is called modernization below.
  • a disadvantage of this method of modernizing an elevator installation is that the transport capacity of the elevator installation is at best maintained during the modernization. If an elevator is exchanged in an elevator installation with, for example, three elevators, this means a temporary reduction of the transport capacity by 33%. Users, on the other hand, do not want to suffer comfort during modernization and continue to be promoted as quickly and directly as possible. Long waiting times or awkward transfers are perceived as unpleasant.
  • the object of the invention is to provide a method and a system in which waiting times or changes perceived as detrimental to the user during the modernization of an elevator installation are largely avoided.
  • This method should be cost-effective and compatible with established standards in mechanical engineering and the electronics industry.
  • an elevator system located in a building is modernized with several elevators in a building.
  • On at least one floor of the building is at least one floor terminal for entering a landing call.
  • the floor terminal is connected to a group controller for communicating an inputted floor call.
  • At least one elevator is controlled by the group control according to the communicated floor call.
  • At least one call detection unit is connected to the group controller for communicating an inputted floor call.
  • At least one new floor terminal will be installed on at least one floor for entering a landing call.
  • the new floor terminal is connected to the call detection unit for communication of an inputted floor call.
  • the existing floor terminals are made inaccessible.
  • a floor call is entered via a new floor terminal, which floor call is communicated to the call detection unit and from there is communicated directly or indirectly to the group control.
  • This has the advantage that on this floor a floor call can only be entered at a new floor terminal.
  • a user is prevented from entering a floor call several times, at an old floor terminal and at a new floor terminal.
  • Such a multiple entry of a landing call unnecessarily reduces the transport capacity of the elevator installation.
  • a new group control is installed. At least one elevator is relocated from the existing group control to the new group control. The suspended elevator is controlled by the new group controller and the call detection unit is connected to the new group controller for communication of an entered floor call.
  • the call detection unit not only communicates with the old group control, but also with the new group control.
  • the call detection unit may communicate with the group controllers in a direct or indirect manner. This makes it possible to adapt the traffic volume during modernization to the changing transport capacity of the elevator installation.
  • the call detection unit is an independent unit or component of a floor terminal.
  • several call detection units are mounted per floor.
  • floor calls entered on the new floor terminal are distributed according to at least one rule to the existing group control and to the new group control.
  • a random distribution or an alternating distribution or a performance-related distribution is used as a rule. This has the advantage that if the new group control is more efficient, ie has a higher capacity than the existing group control, entered floor calls will be specifically allocated to this more powerful new group control.
  • at least one floor, preferably on each floor is fitted with at least one new floor terminal for entering a floor call, and the new floor terminals are connected to the call detection unit for communication of an entered floor call.
  • the starting floor of the entered floor call is communicated by the call detection unit as a start signal to the group control, and the group control communicates the receipt of the entered landing call as an acknowledgment signal to the call detection unit.
  • the call detection unit detects the deactivation of the acknowledgment signal, whereupon the call detection unit communicates the destination floor of the entered floor call as the destination signal to the group control.
  • the new floor terminal is a start-up call terminal or a destination call terminal. If the new floor terminal is a destination call terminal, existing car terminals are made inaccessible. This also avoids multiple entry of a call, once as a destination call at the destination call terminal and then as a car call in the car terminal, which reduces the transport capacity of the elevator system.
  • the call detection unit is dismantled after transferring the last of the elevators from the existing group control to the new group control.
  • the call detection unit can thus be used again in further modernizations.
  • the call detection unit or a new floor terminal on an interface for picking up signals such as start signals, acknowledgment signals and destination signals.
  • signals can be easily and quickly tapped in future modernizations.
  • Fig. 1 shows a schematic view of a part of an elevator system to be modernized. More details are off Fig. 2 refer to.
  • Fig. 2 shows a view of a portion of a floor of the elevator to be modernized according to Fig. 1 .

  • a floor call indicates to the group controller 5 the start floor from which a user wants to be moved with a lift A, B, C in the building.
  • the elevators A, B, C are controlled by the group control 5 according to the communicated floor call.
  • this call is communicated as a start floor to the group control 5.

  • the input of a floor call in the start floor is done for example by closing an electrical contact at the output of the call button 22, 22 ', 22 ", 24, 24', 24", so that an electric current flows, which is detected by the group control 5 as a start signal.
  • the group controller 5 confirms receipt of the landing call by activating an acknowledgment lamp 21, 21 ', 21 ", 23, 23', 23" in the start floor.
  • the receipt of a landing call for an upward drive is confirmed with an acknowledgment lamp 21, 21 ', 21 "
