Definitions

  • the present invention relates to a method for operating a passenger transport system.
  • Passenger transport systems such as elevators, escalators or moving walks are used as permanently installed devices in buildings to transport people and/or objects.
  • Embodiments of the invention are described below primarily with reference to a passenger transport system designed as an elevator system. However, the embodiments described can also be implemented for other types of passenger transport systems.

  • safety-relevant functions can include, for example, measurement processes with which a current state or current conditions within the passenger transport system can be determined, so that information obtained can be taken into account when operating the passenger transport system.
  • a safety device in the form of a door sensor or door switch in an elevator system can be used to determine whether an elevator door is closed correctly, so that an elevator control can decide, based on the information transmitted by several such safety devices on different elevator doors of the elevator system, whether one Move elevator car or whether this is temporarily not permitted due to the fact that at least one elevator door is not closed correctly.
  • Other safety devices can be configured to provide information about the position at which an elevator car is currently located in an elevator shaft and/or how fast the elevator car is currently moving through the elevator shaft.
  • a sensor can be moved through the elevator shaft together with the elevator car and read out local information stored stationarily within the elevator shaft, from which conclusions can then be drawn about the current position of the elevator car and the current speed of the elevator car. Based on this information, an elevator control can precisely move the elevator car to the desired positions.
  • Another type of safety device can be used to detect whether an elevator car is within a tolerance range above and below a stop position on a floor. Based on this information, the elevator control can, for example, decide that elevator doors may be opened before the elevator car has actually reached a targeted stop position, i.e. while the elevator car is still moving within the tolerance range (so-called pre-opening).
  • an elevator control can exceptionally allow the elevator car to move slowly as long as the elevator car is within the tolerance range around the stop position, in order to thereby, for example, To be able to effect level adjustment (so-called releveling) when passengers enter or leave the elevator car and the load and ultimately the position of the elevator car changes.

  • the release can be viewed as a result of the comparison of the two parameters 43, 59.
  • the data processing device 21 can send a sealed signal 57 to the controller 11. Only when the controller 11 receives such a sealed signal 57 can it safely assume that the safety device 17 has been correctly configured and can then control a full range of functionalities of the passenger transport system 1 in a normal mode.

  • the configuration parameter 41 which was automatically read out of the database 37, with that of The configured parameters 43 transmitted back to the safety device 17 can be automatically compared. If both parameters 41, 43 match sufficiently, the sealed signal 57 can be transmitted to the controller 11. It may be possible to request approval from the authorized technician 23 before the sealed signal 57 is transmitted, for example by operating a control panel on the screen 25 of the smartphone 19.
