  • operating parameters transmitted to the security node are also taken into account in the evaluation.
  • Operating parameters taken into account in the evaluation are in particular the speed of the car, the position of the car in the shaft system, the acceleration of the car, the load of the car and the condition of the brakes in the car.

  • the safety node assigned to a car advantageously knows, in addition to the stop points of this car, the stop points of the cars adjacent to this car in the respective direction of travel of this car.
  • the control unit of a safety node assigned to a car as a functional unit is designed to determine the distance from the first stop point of this car to the second stop point of the car adjacent in the first direction of travel. Furthermore, this control unit is advantageously designed to determine the distance from the second stop point of this car to the first stop point of the car adjacent in the second direction of travel.
  • the safety system of the elevator system is advantageously designed to bring the elevator system into a safe operating state at a determined negative distance.
  • a current stop point for a direction of travel of a car is, in particular, the distance that the car needs to stop in this direction of travel.
  • the distance is preferably applied by a safety distance, preferably a fixed safety distance, so that the stop point is correspondingly further away from the car.
  • the distance between the car and the stop point also changes for each direction of travel. In particular, the speed at which a car is moved also increases the distance of the corresponding stop point from the car.
  • the minimum distance between two adjacent cars can be dependent on several operating parameters, in particular the current position of the cars in the shaft system, the speeds of the cars, the accelerations of the cars, the payloads of the cars and / or the states of the brakes of the cars , These operating parameters are preferably only recorded individually for each car in order to use these operating parameters for each car for the at least one direction of travel to determine the respective stop point.
  • operating parameters are preferably only recorded individually for each car in order to use these operating parameters for each car for the at least one direction of travel to determine the respective stop point.
  • the elevator system is advantageously switched to a safety mode, in particular in the corresponding one neighboring cars, the stopping points of which are at a negative distance, are braked and thus brought to a stop, in particular by triggering safety devices in these cars.
  • negative distance denotes the case where the stop point of a car in question is further away from this car than the stop point of an adjacent car, in particular a car traveling ahead or behind. Whether the distance is actually negative in the sense of a negative number depends on the reference system used. For example, a "negative distance" in a corresponding reference system can also be expressed by a positive number.
  • Both horizontal and vertical movements of the cars can advantageously be taken into account and corresponding stop points can be predicted.
  • a rapid detection of possible collisions is advantageously provided.
  • the stopping point of each car is predicted, assuming that at least one safety device of the elevator system intervenes at the latest, the respective car is stopped.
  • the prediction is thus advantageously designed to be conservative.
  • Safety devices of the elevator system are, in particular, braking devices, such as safety devices for the cars and / or braking devices provided by the drive system. If the drive system of the elevator installation comprises at least one linear drive, the section-by-section shutdown of a line of the linear drive is also provided as intervention by at least one safety device.
  • a further advantageous embodiment of the invention provides that the stop points are each predicted on the assumption of a worst case scenario in order to reliably prevent a collision between adjacent cars in any case.
  • the stopping point is predicted by each car on the additional assumption that the respective car is accelerated with the maximum possible acceleration on the part of the elevator system before the at least one safety device of the elevator system intervenes.
  • the stopping point in the direction of travel "up” below is therefore more advantageous.
  • the assumption predicts that the car is first accelerated to the maximum in the direction of travel “above” and is then stopped by intervention of at least one safety device.
  • the stop point in the direction of travel "below” is advantageously predicted on the assumption that the car is first accelerated to a maximum in the direction of travel “below” and is then brought to a stop by intervention of at least one safety device. Due to the gravity acting on the car, which is advantageously taken into account in the prediction of the stop points, the distance of the stop point in the direction of travel "up” to the upper end of the car is less than the distance of the stop point in the direction of travel "down” to the lower end of the car.
  • an upper stop point and a lower stop point are continuously predicted for each car in a vertical shaft of the shaft system of the elevator installation, in which at least three cars are moved.
  • all of the cars thus have an upper adjacent car and a lower adjacent car.
  • the distance between the upper stop point of one car and the lower stop point of the upper adjacent car is determined.
  • the distance between the lower stop point of a car and the upper stop point of the lower adjacent car is also advantageously determined.
  • the stop points are advantageously defined using a grid that is permanently assigned to the shaft system.
  • a grid that is fundamentally suitable for this is, for example, from the publication EP 1 719 727 B1 known.
  • the stop points can be represented in particular as coordinates (x, y) or (x, y, z). Only the corresponding coordinate is preferably taken into account for a current direction of travel, for example only the coordinate x for direction of travel x. Particularly in the areas in which the direction of travel changes, for example from the direction of travel x to the direction of travel y, it is advantageously provided that more than one coordinate is taken into account here in each case for a corresponding section comprising the transition area, i.e. in relation to the example given above Coordinates (x, y).
  • the elevator system is switched to a safety mode, in particular by stopping at least one of the two cars. The same applies accordingly if the lower stop point of a car is smaller than the upper stop point of the car traveling below this car.
  • Possible collision risks of a car with an upper adjacent car and / or a lower adjacent car are thus reliably identified, namely by checking whether a determined distance is negative, that is to say the stop points compared with one another have an overlap area. If a negative distance is determined, the elevator system is advantageously switched from normal operation to a safety mode, in particular by stopping the affected cars.
  • the other cars are advantageously further moved in restricted operation, the stopped cars defining a restricted area to which the cars still operating may only approach up to a predefined distance.
  • the cars stopped during the transfer of the elevator system into a safety mode are preferably assigned fixed stop points, so that in particular a collision of cars with the stopped cars is further prevented using the same method.
  • Each control unit assigned to a car advantageously calculates the stop points for the at least one direction of travel of this car, in particular an upper and a lower stop point, and exchanges them with those of the control units of the adjacent cars. Instead of calculating the distances between adjacent cars, the stop points are advantageously compared with one another, as already explained above. As long as the stop points do not overlap, i.e. a negative distance is determined, there is no risk of collision.
  • the control unit of a car preferably triggers a securing device for this car when a negative distance between the stopping points is determined, it being provided in particular that triggering the securing device causes the car to stop.
  • the actuation of a brake of the car is provided as the triggering of a safety device of the car.
  • the control device assigned to one car is only responsible for the safety device of this car with regard to the triggering of safety devices and advantageously does not also have to brake other cars. As a result, the amount of data to be transmitted is advantageously further reduced.
  • the stop points are predicted from current operating parameters of the respective car. According to an advantageous embodiment variant, it is provided that stop points are predefined for all quantized combinations of operating parameters. According to an advantageous embodiment, the stop points are assigned to such a combination of operating parameters via a lookup table. In particular, according to a further advantageous embodiment variant, such an assignment is provided as a plausibility check of stop points predicted by real-time calculations. When a predefined deviation from assigned stop points and predicted stop points is ascertained, the elevator system is also advantageously switched to a safety mode.
  • the elevator system according to the invention in particular the respective components of the elevator system, is designed to carry out the method steps described in connection with the invention.
