Definitions
- the present invention relates to a mobile device or a method for monitoring an elevator system in a multi-storey building and an elevator system that can be monitored by such a mobile device or method.
- Elevators serve to transport people through an elevator car within an elevator shaft of a building and between different floors.
- the elevator system In order to be able to ensure the safety of passengers or service personnel, the elevator system must be inspected and serviced regularly or periodically.
- an elevator installation In order to carry out an inspection and maintenance work, an elevator installation must be put into an inspection or maintenance operating mode, in which the elevator car may only move between certain positions at walking speed only by manual control.
- a service technician usually first has to get into the elevator shaft via a shaft door or maintenance hatch, because an inspection operating device is usually located in the shaft, namely on the roof the elevator car or in the shaft pit of the elevator system is arranged.
- a door contact switch is typically provided on each shaft door and the car door of an elevator installation, which is closed as long as the car door and/or the shaft door are closed and remains open as long as one or both doors are open.
- Such door contact switches are connected in series with other safety elements of the elevator installation, as a result of which a safety chain of the elevator installation as a whole is only closed when all door contact switches are closed.
- the safety chain is broken when a so-called "Contact Unlock Landing Door Switch" (KNET Switch) is unlocked outside of an elevator shaft, the KNET Switch typically being actuated by a triangular key.
- KNET Switch Contact Unlock Landing Door Switch
- the KNET switch is used for maintenance/inspection work for an elevator system in order to be able to open a shaft door of the elevator system on a floor manually, regardless of the current position of the elevator car. If the KNET switch is activated, the elevator car is moved beyond a permissible travel distance, for example in the direction of an elevator shaft ceiling or in the direction of an elevator shaft floor. In contrast to a door contact switch mentioned above, regardless of where the elevator car is located, a landing door can be opened manually by unlocking the KNET switch. If the shaft door is opened, the elevator car is stopped immediately because of the broken safety chain.
- the current position means above and below that the position of the elevator car displayed on the mobile device is precise, i.e. it appears to the viewer continuously and not discretely and at small time intervals, e.g. at a time interval of less than a millisecond, the position of the actual position adapted to the cabin.
- the displayed position corresponds to the actual position of the car at all times.
- the mobile device is designed in such a way that the current position of the elevator car in the elevator shaft can be displayed on the screen of the mobile device in relation to the respective positions of all floors of the building.
- the elevator car and the respective floors are advantageously displayed on the screen of the mobile device in proportion to their size.
- a maintenance stop position of the elevator car can be displayed on the screen, with the maintenance stop position already being predefined for a specific maintenance task, and with the maintenance task being able to be determined either by the mobile device or by a remote control center for the elevator system.
- a method for monitoring an elevator system in a multi-storey building is provided, with an elevator car being moved under the control of an elevator controller of the elevator system in an elevator shaft of the elevator system between the floors of the building.
- a mobile device as described above communicates continuously with the elevator system, in particular with the elevator controller or the elevator car, via the position data of the elevator car in such a way that the current position of the elevator car in the elevator shaft compared to the position of at least one floor of the building on the screen of the mobile device is continuously displayed becomes.
- an elevator installation is provided in a multi-storey building, with an elevator car being able to be moved in an elevator shaft of the elevator installation between the floors of the building under the control of an elevator controller of the elevator installation, with the elevator installation being able to be monitored by means of a mobile device mentioned and described above or by one illustrated above procedure is monitored.
- the current position of the elevator car in the elevator shaft compared to the respective positions of all floors of the building can be displayed continuously on the screen of the mobile device.
- the actual Position of the elevator car can be a stationary stop position or a current position that moves continuously during travel of the elevator car.
- a mobile device 2 for monitoring the elevator installation 1 is provided.
- the mobile device 2 is, for example, a smartphone or any portable communication device.
- wireless communication can be established with the elevator control 10 or the elevator car 5, so that the mobile device 2 can monitor and control the movement or the position of the elevator car 5 .
- the mobile device 2 can control the elevator system 1 accordingly. That is, a technician, ie the user (not shown) of the mobile device 2, can switch the elevator system 1 to the inspection mode or normal mode using the mobile device 2 both outside and inside the elevator shaft 6. It is then no longer necessary to arrange an inspection control panel 12 in the elevator shaft 6 , namely in the shaft pit and on the roof of the elevator car 5 .
- the functions of the inspection control panel 12 can be at least partially taken over by the mobile device 2 . Thus, it is no longer necessary for the technician to make an effort to first enter the elevator shaft 6 in order to switch the elevator installation 1 to the inspection mode before maintenance work is to be carried out.
- FIG. 2 shows a mobile device 2 according to the invention with a screen 4.
- an elevator system 1 which is shown for example in FIG the position of a floor 7 or the respective positions of several or all floors 7 of the building 3 can be continuously graphically displayed on the screen 4.
- the elevator car 5 and the respective floors are proportional to their size displayed.
- a highest 14a and/or lowest stopping position 14b in the elevator shaft 6, which the elevator car 5 can reach, can also be displayed on the screen 4.
- a destination floor for a trip of the elevator car 5 is given, a starting position and a destination position of the booked trip of the elevator car 5 can be displayed on the screen 4, such as, for example, the starting position or the destination position is indicated by a diagonally hatched area on the left or right .
- the display on the screen 4 can be zoomed in or out, so that the user of the mobile device 2 has a different or better perspective of the position of the elevator car 5 in relation to the respective floors 7 .
