Abstract
A method for operating an elevator system with a car that moves in an elevator shaft may involve detecting an operating parameter related to a change in loading of the car, ascertaining whether a position of the car relative to a stopping floor needs to be adjusted based on the operating parameter, determining times at which the car is to be stopped and at which the adjustment is to be performed, stopping the car and blocking a flow of energy of a drive of the car and/or activating a service brake as the car is being stopped and/or while the car is stopped, and adjusting the position of the car if necessary. Further, whether the adjustment is necessary may be ascertained before the car is stopped.
Claims19
A method for operating an elevator system comprising a car that is moved in an elevator shaft, the method comprising:
- detecting an operating parameter related to a change in loading of the car;
- ascertaining whether an adjustment of a position of the car relative to a destination floor is necessary based on the operating parameter;
- if the adjustment is ascertained to be necessary, determining a first time at which the adjustment is to be performed;
- determining a second time at which the car is to be stopped;
- determining the first and second times before bringing the car to rest at the destination floor, wherein each of the first and second times is determined relative to an absolute time or relative to a time period during which the car is at rest at the destination floor;
- stopping the car at the destination floor by at least one of blocking a flow of energy of a drive of the car or activating a service brake;
- and
- if the adjustment is ascertained to be necessary, adjusting the position of the car to the destination floor whereby the position of the car in the elevator shaft relative to the destination floor is set,
- wherein whether the adjustment is necessary is ascertained before the car is stopped.
An elevator system comprising:
- a car that is movable in an elevator shaft;
- and
- a control unit that
- detects an operating parameter related to a change in loading of the car,
- ascertains whether an adjustment of a position of the car relative to a destination floor is necessary based on the operating parameter,
- if the adjustment is ascertained to be necessary, determines a first time at which the adjustment is to be performed,
- determines a second time at which the car is to be stopped,
- determines the first and second times before bringing the car to rest at the destination floor, wherein each of the first and second times is determined relative to an absolute time or relative to a time period during which the car is at rest at the destination floor,
- stops the car at the destination floor by at least one of blocking a flow of energy of a drive of the car or activating a service brake, and
- if the adjustment is ascertained to be necessary, adjusts the position of the car to the destination floor whereby the position of the car in the elevator shaft relative to the destination floor is set.
A method for operating an elevator system comprising a car that is moved in an elevator shaft,
- wherein the car is brought to rest at a destination floor;
- wherein the car is stopped at the destination floor, the stopping of the car involving a flow of energy being blocked and/or a service brake being activated, wherein in a case of the flow of energy being blocked a flow of energy of a drive of the car is blocked;
- wherein if adjustment is required a position of the car is adjusted to the destination floor, wherein the car position in the elevator shaft relative to the destination floor is set during a course of the adjustment;
- wherein at least one operating parameter that relates to a change in loading of the car is detected;
- wherein depending on the at least one operating parameter at least before the car is stopped, it is ascertained whether adjustment to the destination floor is required;
- wherein if it is ascertained that adjustment is required, a first time at which the adjustment is carried out is determined, and a second time at which the car is stopped is determined before bringing the car to rest at the destination floor, and
- wherein each of the first and second times is determined relative to an absolute time or relative to a time period during which the car is at rest at the destination floor.
