Definitions

  • the present invention relates to a method for operating an elevator system and a corresponding elevator system.
  • High-rise buildings and buildings with a large number of floors require complex elevator systems in order to handle all transport processes as effectively as possible.
  • a large number of users want to be transported from the ground floor of the building to the different floors of the building.
  • a large number of users should be transported from the different floors to the ground floor.
  • Elevator systems for such purposes are known.
  • Single-car systems or single-car systems have, for example, a car in an elevator shaft.
  • Double-decker car systems have two cars in one elevator shaft. These two cabins of a double-decker cabin system are mostly firmly connected to one another and can usually not be moved independently of one another.
  • Multi-car systems have at least two cars in an elevator shaft. These cabs in a multi-cab system can be moved independently of one another.
  • Such multi-car systems with two independent Cars which can be moved from one another in an elevator shaft are sold by the applicant under the name "TWIN".
  • a shaft-changing multi-car system comprises a plurality of cars that can be moved in a group of elevator shafts.
  • the cars can not only be moved back and forth vertically in the individual elevator shafts, but also horizontally between the individual elevator shafts.
  • Cars of a shaft-changing multi-car system are therefore not permanently tied to an elevator shaft, as is the case with single-car systems or conventional multi-car systems.
  • the cars of a shaft-changing multi-car system can switch between the elevator shafts at an upper and / or at a lower end of the elevator shafts.
  • Appropriate changer facilities are provided for this purpose.
  • the shaft-changing multi-car system comprises more than two elevator shafts, the individual cars can in particular switch between all of these elevator shafts.
  • Such a change of cars between elevator shafts can be carried out, for example, only between adjacent elevator shafts, or in particular also flexibly between non-adjacent elevator shafts.
  • an elevator system with several elevator cars which can be moved in three shafts. It is provided that if there is a high demand for journeys to the upper floors, two of the three shafts are assigned an upward direction of travel and one of the three shafts is assigned a downward direction of travel. If the demand changes so that there is a high demand for trips to the lower floors, the assigned direction of travel is reversed so that the two shafts that were previously assigned an upward direction are assigned a downward direction and the one shaft that was previously assigned a downward direction , an upward direction is assigned.
  • the present invention seeks to improve the effectiveness of shaft changing multi-car systems.
  • the directions of travel assigned to the individual elevator shafts are advantageously reversed.
  • a reversal of direction for the individual shafts thus advantageously takes place one after the other.
  • the direction of the individual cabins is advantageously reversed individually and one after the other.
  • the means are advantageously set up in such a way that the directions of travel assigned to the individual elevator shafts are successively reversed in order to get from the first operating state to the second operating state.
  • the means are advantageously designed in such a way that the direction reversal of individual cabins takes place individually and one after the other.
  • the direction of the individual shafts is correspondingly reversed one after the other.
  • an elevator system is enabled to switch between different operating states in a very effective manner.
  • cars that are located in a respective elevator shaft can only move in the upward or downward direction, includes that these cars also, for example in the case of a car call by a user, in one can stop corresponding floor. Only a movement of the car in the direction opposite to the assigned direction of travel is excluded.
  • control device can be integrated into the overall control of an elevator system, or it can also interact with a corresponding elevator control.
  • the invention enables an increase in the conveying capacity of an elevator system in a main direction of travel, to which the majority of the elevator shafts are assigned at a specific time, by minimizing the average cycle time of the cars in the main direction of travel.
  • Under the Average cycle time is understood to be the average time between the passage of two successive cars through a specific floor, for example a main stop such as the ground floor stop.
  • the cycle time depends mainly on the holding times of the cars on individual floors, the cycle time being increased in particular when different cars are to stop on the same floor.
  • the stopping times include in particular the time to open and close the respective elevator or car doors, as well as the time to get on and off passengers. Safety clearances between individual cabins must also be taken into account.
  • a plurality of elevator shafts is assigned an exclusive direction of travel UP and a minority of elevator shafts is assigned a direction of travel DOWN
  • a plurality of elevator shafts is assigned an exclusive direction of travel DOWN and a minority of elevator shafts has an exclusive direction of travel UP assigned, or vice versa.
  • the method according to the invention offers a very effective possibility of conversion.
  • a movement of cars between the elevator shafts is carried out in an upper and / or a lower area of the respective elevator shafts.
  • Appropriate changer facilities are provided for this purpose.
  • the method is particularly preferably used for operating an elevator system with at least one group of three elevator shafts, wherein in each of the at least one group in the first operating state two shafts are assigned an exclusive direction of travel UP and one elevator shaft is assigned a direction of travel DOWN, and in the second operating state two elevator shafts an exclusive travel direction DOWN, and an elevator shaft an exclusive travel direction UP is assigned.
  • information YES or NO is assigned to each cabin, such that in the event that information YES is assigned to a cabin, this cabin is available for the transport of passengers , and if NO is assigned to a cabin, this cabin is not available for the transport of passengers.
  • cabins which, in particular, are not moving in a current main direction of travel of the elevator system, can be blocked for use by passengers. In this way it can be ensured that such cars can be transported again particularly quickly into an elevator shaft to which the main direction of travel of the elevator system is assigned. The conveying capacity of the elevator system can thus be increased overall.
  • the assignment of the information YES or NO is also expediently carried out by the control device.
  • this car in the event of an assignment of NO to a car, this car can be moved in the upward or downward direction corresponding to a direction of travel assigned to a respective elevator shaft in which it is located, but not for the reception of passengers or users Available.
  • NO is assigned to a cabin, there will be no people or passengers in this cabin.
  • the status NO is only assigned to a car if it is located in an elevator shaft which belongs to a current minority of elevator shafts. This can ensure that the majority of the elevator shafts, which expediently move in the main direction of travel of the elevator system, can be used in an optimal way for passenger transport.
  • the recorded information can be, for example, an ascertained or forecast traffic volume, it being possible for this to be ascertained or forecast in different ways.
  • corresponding sensors can be provided for this purpose, which detect passengers in individual cabins and / or in the vicinity of the elevator system. Separation systems can also be used for this purpose be provided in the vicinity of the elevator system. It is also conceivable to provide a learning system in this context.
  • FIG 1 an elevator system having three elevator shafts (110, 120, 130) is shown schematically and denoted as a whole by 10.
  • the elevator system 10 is designed as a shaft-changing multi-car system. This means that cars that can be moved in the individual elevator shafts (110, 120, 130) can also be moved between the individual elevator shafts (110, 120, 130). To simplify the illustration, the individual cabins are shown in Figure 1 not shown.
  • the elevator system has a control device which is shown schematically and denoted by 160.
  • more cars than elevator shafts are typically provided.
  • two or more cars can be provided per elevator shaft, it being possible for more than two or less than two cars to be in a specific shaft at certain times, for example.
  • Such an elevator system 10 has at least two changer devices, by means of which the respective cars can be moved between the elevator shafts (110, 120, 130).
  • These changer devices are preferably provided in an upper area, in particular the top floor, and the lower area, in particular the lowest floor or the ground floor. However, it is also possible to provide such changer devices on any floors.
  • the elevator system 10 is able to assign a direction of travel in the upward direction to a plurality of elevator shafts (hereinafter referred to as the direction of travel UP) and a corresponding minority of elevator shafts to assign a direction of travel in the downward direction (hereinafter referred to as the direction of travel DOWN), or vice versa .
  • FIG. 1 State A shows a first operating state in which the two outer elevator shafts 110, 130 are assigned an UP direction of travel and the elevator shaft 120 located in the middle is assigned an DOWN direction of travel.
  • the cars located in the elevator shafts 110, 130 move in the upward direction, and when the top floor is reached, they are moved into the middle elevator shaft 120 by means of the corresponding changer device, and are moved in this in the downward direction.
  • the cars are in turn moved by means of a corresponding changer device into one of the outer elevator shafts 110, 130, where a renewed upward movement takes place.
  • the cars arriving on the lowest floor are expediently moved alternately into the (left) elevator shaft 110 and the (right) elevator shaft 130.
  • the first operating state shown as state A is particularly suitable for morning operation in which many passengers enter a high-rise building and have to move to different floors or, for example, also to an upper floor, for example a transfer floor.
  • This second operating state is particularly suitable for times when more passengers leave a high-rise building than new ones enter it, for example for after-work situations.
  • the invention proposes a successive reversal of the directions of travel assigned to the individual elevator shafts, as will be explained below.
  • State B can be brought about, for example, by informing passengers who are in a car in the elevator shaft 130 that they have to get off and their journey in another car, for example a car in the elevator shaft 110, have to continue.
  • State B can also be brought about by the fact that the assignment of the direction of travel in elevator shaft 130 is only canceled when all passengers who are in a car in elevator shaft 130 have reached their destination floors. This can in particular also take place successively, for example by blocking a car that has reached the destination floor of a passenger in elevator shaft 130 for further journeys until all passengers in cars that are located in elevator shaft 130 have reached their destination floor.
  • the elevator shaft 110 is available for upward travel and the elevator shaft 120 is available for downward travel.
  • the assignment of the direction of travel UP of the middle elevator shaft 120 is canceled. This is shown in state D. It can be seen that in this state the directions of travel assigned last to the elevator shafts 110, 130 are retained, in particular in this state D at least one elevator shaft is provided in which journeys in the upward direction and at least one elevator shaft in which journeys in the downward direction are possible, maintained. In state D it may be necessary to relocate or move cars between two non-adjacent elevator shafts. In a subsequent step, the direction of travel assigned to the middle shaft 120 is reversed, so that, according to state E, the elevator shaft 120 now has an assigned direction of travel UP.
  • control device 160 assigned to the elevator system can, for example, learn or optimize certain traffic patterns or profiles at certain times of the day and / or week by means of inputting or learning corresponding information relating to the main traffic volume or main directions of travel.
  • the elevator system can, for example, with sensors via which z. B. a number of passengers in a cabin or in a building can be determined, call input devices, or additional detection means for passengers, such as cameras, isolation devices, etc. can be equipped.
  • Corresponding main directions of travel predicted by a control device for example according to the first operating state (state A) in the upward direction, or according to the second operating state (state G) in the downward direction, can be learned or set accordingly by the elevator control so that the elevator control can determine Times the main direction of travel can reverse as referring to above Figure 1 explicitly shown.
  • Such a method or elevator system can be further optimized by using, for example, interfaces for user inputs, in particular call inputs, and / or display devices for displaying information for passengers. This makes it possible, for example, to identify or optimize passenger behavior at an early stage. Furthermore, a current operating state can be displayed in this way, for example. For example, it is also possible to specify expected arrival times and preferred cars or elevator shafts to be used to display the users or passengers, so that an efficient passenger transport can be provided.
  • a total of 11 cars 100 for three elevator shafts 110, 120, 130 are provided.
  • a total of 15 cars 100 for a total of five elevator shafts 110, 120, 130, 140, 150 are provided.
  • the allocation of the respective directions of travel UP and DOWN can be seen from the corresponding arrows.
  • Figure 2 is an operating state corresponding to the first operating state (state A) of the Figure 1 shown.
  • the main direction of travel is therefore the upward direction.
  • an average travel time of a car 100 in an elevator shaft 110 or 130 from the lowest floor 111 to the uppermost floor 121, where the car is moved horizontally into the elevator shaft 120 by means of a changer device is significantly longer than that Duration of a descent from the top floor 121 to the bottom floor 111.
  • the conveying capacity of the elevator system as a whole can be increased in that a portion of the cars 100 moving in the elevator shaft 120 in the downward direction is not available for passenger traffic.
  • each car 100 located in the elevator shaft 120 can be assigned YES or NO information by the elevator controller 160, the assignment of this information determining whether the respective car is available for passenger traffic or calls in a direction of travel AB.
  • the average cycle time or cycle time i.e. the time between two consecutive cars at one location, for example a main stop, is reduced, so that overall the time for an up and down movement of a car can be reduced . This increases the overall effectiveness or delivery rate of the system.
  • n of m cars (with n ⁇ m).
  • the decision about this can be made by the control system on the basis of various information, e.g. learning system, sensors, isolation systems, etc.
  • the method according to the invention can be used particularly advantageously in connection with so-called shuttle elevators.
  • shuttle elevators are used to transport passengers over a large number of floors without stopping.
  • Typical shuttle elevators run between a ground floor and a transfer floor in a higher area of a high-rise building. If, for example, the main direction of traffic is in the morning, the upward direction, it can be ensured according to the invention that cabins moving in downward movement can be returned to shuttle operation in the upward direction in a very effective manner.
