Abstract

A display device for a lift system with at least one lift shaft (1.1, 1.2), in which several lift cabins (2.1-2.4) travel, comprises an allocation manager, in order to allocate an identifier ("A1", "A2", "A3") to a lift cabin carrying out a transport job and a display (5.60, 5.70, 5.100), provided for a boarding location (4.6, 4.7, 4.10) for output of an identifier, wherein the display can simultaneously display the identifier for several lift cabins.

Description

Display device and communication method for an elevator system

The present invention relates to a display device for an elevator system and a method for communicating with such an elevator system.

To increase the transport capacity, it is known, for example from EP 1 046 605 Bl, to provide a plurality of elevator cars in an elevator shaft of a so-called multi-vehicle elevator. Advantageously, moreover, several such elevator shafts may be present. If a user enters a destination call, an elevator controller assigns a corresponding transport order to one of the existing elevator cars and informs the user which elevator car he should use. To this end, the controller informs the user of a specific identifier assigned to the elevator car carrying out his transport order and displays this identifier at a delivery location if the corresponding elevator car is available there.

Thus, in the exemplary embodiment of EP 1 046 605 B1, the elevator control informs a user of the designator "B3." If an indicator assigned to the elevator shaft "B" now outputs the designator "Bl", the user recognizes that the elevator car designated therewith does not Only when the display outputs the identifier "B3", the user knows that this elevator car will now carry out its transport order, and rises. Thus, the flow of people can be divided and thus optimizes the lift capacity. In the aforementioned embodiment, for example, the "Bl" cabin could travel without interruption to the top floors, while the "B3" cabin served only the lower floors.

In the method disclosed in EP 1 046 605 Bl, the user has no insight into the elevator system. In particular, he does not know in advance when "his" elevator car will be available at the boarding location, since only the identifier of the elevator car next to it or next to the floor will be output.The user is forced to wait for his Always be aware of the display of the place of shipment, there is therefore a considerable risk that the user may missed or erroneously gets into the wrong elevator car.

The object of the present invention is therefore to provide an improved display device or an improved communication method.

This object is achieved by a display device having the features of claim 1. Claim 10 protects the corresponding method.

According to the present invention, a display device for an elevator system is proposed which has at least one elevator shaft in which several

Move elevator cars. The display device comprises at least one identifier manager, which assigns a temporary identifier to an elevator car executing a transport request, and at least one display associated with a delivery address, preferably for visual output, of the allocated identifier, the display simultaneously outputting the identifiers of several elevator cars.

Preferably, the elevator cars thereby move autonomously, i. essentially independent of each other, of course, a collision of elevator cars must be excluded. Similarly, individual or all elevator cars can also move in a coupled manner.

The elevator cars can move only vertically or vertically and horizontally.

A horizontal movement allows the transfer of one elevator car to another

Elevator shaft or an intermediate storage, which advantageously allows the formation of pure up and down shafts. The division into up and down shafts is not necessarily fixed - so, for example, at the beginning of a working day, one or more elevator shafts can be used as upward shafts, which at the end of

Working days are used as downward shafts.

The identifiers manager associated with each submission location can be designed as part of a central elevator control which, according to certain criteria, for example the

Allocate capacity, the positions or the destinations of the cabins to a transport order of a specific elevator car, and at the same time allocate this identifier to its identifier.

Advantageously, the allocation of the identifier can be summarized in one place and Managed jointly and so the communication with independent systems are reduced. The concept of a central elevator control does not necessarily mean a physically centralized control - a central elevator control within the meaning of the present invention can equally be realized, for example, by elevator car controllers communicating with one another.

Alternatively, the identifier manager for each Zusteigeort be designed as a stand-alone system that the central elevator control that has registered the destination call of the user and has selected an elevator car to fulfill the transport order, the identifier that assigns the independent system of this elevator car for this Zusteigeort. This advantageously relieves the central elevator control. In this case, however, it should be ensured that the identifier managers never assign the same identifiers for different locations on one floor. Such an autonomous system can for example be integrated in a destination call station in which a user can place his destination call.

Also mixed forms are possible. For example, an identifier manager may be provided for each floor and assign identifiers to the elevator cars for that floor, notifying these identifiers to the central elevator controller. This combines the advantages of the solutions described above.

A Zusteigeort can be formed in particular by a hoistway door in a floor. Are accessible from a floor of elevator cabins in several, for example, side by side and / or oppositely arranged elevator shafts, so make their elevator shaft doors corresponding to several Zusteigeorte on this floor. If an elevator car is accessible on one floor from two or more hoistway doors, then equally each hoistway door or several, in particular all elevator hoistway doors, through which the elevator car is accessible on this floor, can jointly define a submission location.

If each elevator shaft door has its own forwarding location, different users of the same elevator car can be directed through the various elevator shaft doors by having their own elevator cabin for each location, ie for each elevator shaft door Identifier assigned and the different users each one of these identifiers is communicated. For example, an elevator car accessible through two hoistway doors "A" and "B" on the same floor may have a designator associated with the hoistway door "A" designating the identifier "AI", and a designator associated with the hoistway door "B" designating the identifier "Bl". to assign. If half of the users waiting on this floor who are to be transported with this elevator car are given the identifier "AI", the other half the identifier "Bl", then the users are split up onto the two elevator shaft doors, which considerably reduces the approach time ,

Alternatively, the hoistway doors leading on a floor to an elevator car can also form a common forwarding location, leaving it to the users which hoistway doors they use. In this way, fewer different identifiers must be managed and issued.

As a floor not necessarily vertically spaced levels are referred to herein. For example, the elevator shaft doors to several elevator shafts for structural reasons, be vertically spaced from each other, for example, in a hotel lobby. However, these elevator shaft doors can be assigned to the same floor, in this case the hotel lobby. For the division into floors, it is rather important whether different Zusteigeorte, especially elevator shaft doors, for a user equally reachable, so for example, are recognizable and can be kept in view.

Since a transport order in addition to the destination and the starting position, for example, the floor in which the user is located, the same elevator car can be assigned different identifiers on different floors to forward different users at different Zusteigeorten the same elevator car. For example, an elevator car in a floor in which only their elevator shaft has a Zusteigemöglichkeit assigned an identifier "2", in another

Floor, where several lift shafts each have a possibility to board, a designator "B2" to specify the lift shaft on this floor, Similarly, an elevator car can at a Zusmitigemöglichkeit the identifier "B2" be assigned to another Zusteigemöglichkeit the same cabin the identifier "B4" will be assigned.

For each Zusteigeort a separate identifier manager is preferably provided, which, as stated above, formed as an independent system, but can also be implemented in a system for several Zusteigemöglichkeiten, such as on a floor, or a central elevator control.

Each identifier manager includes a memory storing a number of identifiers which the identifier manager assigns to elevator cars selected by the elevator controller for a stop at the dispatch location associated with the identifier manager. The memories, which are preferably formed from electronic components, are designed in such a way that only identifiers that are not currently allocated are removed for the identifier manager for assignment to elevator cars. The number of identifiers stored in each memory is less than the number of elevator cars used for the

Execution of a transport request can be selected from a Zusteigeort assigned to this memory from. For the user of elevator systems with many elevator cars this has the advantage that he is not forced to memorize each one selected from a variety of different identifiers identifiers, but for example, only one of a selection of three possible identifiers.

In this way, a very simple and reliable display device is provided, which ensures that at a Zusteigeort an identifier never simultaneously designates two elevator cars, without requiring a complex management of the identifier, in particular their marking as free or reserved, would be required.

Such a memory may for example be designed as a first-in-first-out memory (FIFO memory). Stored identifiers are successively removed from the memory, allotted to the elevator cars provided for a stop at the assigned forwarding location and, at the latest when the corresponding elevator car leaves the Zusteigeort again supplied to the memory.

Also in an identifier manager for several Zusteigeorte, for example, on one Floor, or a central elevator control is thus preferably for each Zusteigeort a separate memory provided, however, must not be designed physically independent, but can also be represented for example by appropriate partitioning in the context of a larger physical memory.

A memory can also be designed by software. In this context, memory is referred to in the abstract as any memory management that outputs successive elements (identifiers), whereby it is ensured that each of the elements is only output if it is not already being used as an identifier, ie. H. if a particular element has been returned to memory after use or has been registered as no longer in use.

A display device according to the present invention includes a display for outputting one or more identifiers associated with a submit location. Preferably, the assignment is spatially, for example, by the display is arranged next to, above or in the vicinity of a hoistway door. Equally, however, the assignment can also be more abstract, for example by outputting identifiers for different hoistway doors of a floor on a central display. For this purpose, for example, in a site plan next to the individual hoistway doors the identifiers of the corresponding elevator cars are issued. A display in the sense of the present invention may be an identifier both optically, in particular in the form of alphanumeric characters, symbols and / or colors, acoustically, in particular in the form of spoken words, melodies or sounds, haptic, in particular in the form of braille characters, or in any other perceptible way.

Preferably, an identifier, as soon as the elevator car to which he has been assigned leaves the Zusteigeort, supplied to the memory and is thus available again. This makes it possible to notify an additional user later arriving at the elevator car still lingering at the point of arrival as an elevator car which also executes its transport order, if, for example, the transport orders are identical or can be reconciled with one another. Alternatively, the identifier can also be fed back to the memory as soon as the elevator car to which it has been assigned arrives at the forwarding location. Thus, this identifier is available again early for allocation, what the number of necessary identifiers and thus the capacity of the memory reduced. For example, according to another alternative, the identifier may be returned to the memory and the corresponding indicator cleared as soon as the hoistway door begins to close. This avoids too late and therefore dangerous boarding by late-arriving users. In any case, it is advantageous not to output the identifier on the associated display as soon as it is returned to the memory.

In particular, if several lift shafts offer a possibility of boarding on at least one floor, the identifier may comprise a shaft-specific share. This makes it possible to clearly instruct the user a specific elevator car in a particular elevator shaft. The display then preferably displays the entire identifier, including its shaft-specific portion, for example "U2", where "U" the hoistway "and" 2 "designate a particular car moving therein. This advantageously makes it possible to assign the designations of the elevator shafts dynamically and to designate the same elevator shaft, for example, once with "U" (for "Up"), at another with "D" (for "Down"), which increases the flexibility. In addition, such a uniform identifier can be provided, whose appearance on the display corresponds to the one that has been communicated to the user. This is particularly advantageous for illiterate or foreign users who do not understand the characters used for the identifier and merely compare them photographically. Alternatively, it is also possible to permanently display the shaft-specific portion not on the display but, for example, above the respective elevator shaft door. This reduces the display and thus the control, maintenance and production costs, but requires the user a greater transfer performance, since he now has to assign an identifier "U2" the elevator car, for example, on the display of marked with "U" elevator shaft with " 2 "is designated.

The identifiers can include a cabin-specific portion, which is used to distinguish the individual elevator cars within an elevator shaft. Preferably, the cabinet-specific portions are taken in order from a font and / or character set, for example, the natural numbers 1, 2, 3, ... in Arabic or Roman representation. This allows a particularly memorable representation of the identifier and also simplifies their management. According to the invention, a display device for an elevator system with at least one elevator shaft in which several elevator cars move, and which comprises an identifier manager for temporarily assigning an identifier to an elevator car executing a transport request, is assigned to a forwarding location

Display for the output of several elevator cars simultaneously, advantageously in the order in which they will arrive at Zusteigeort. This sequence can be represented by a spatial arrangement next to or above each other, for example. This gives the user an insight into the elevator system and thus can better estimate, for example, his waiting time. In addition, he can be signaled at an early stage that his transport order has been assigned to an elevator car - he can, so to speak, follow the path of his "elevator car." Preferably, at least the identifiers of the next two or three elevator cars will be displayed, which will stop at the forwarding location.

For example, if the memory contains the natural numbers 1, 2, 3, ... in chronological order

Sequence, possibly with the introduction of a shaft specific share in the form of a Latin capital letter "A", "B", "C", ..., then the first elevator car, which will stop at this Zusteigeort, the identifier "1" (or "AI", "Bl", ...), the next elevator car the identifier "2" (or "A2", "B2", ...) and so on. Once an elevator car has left the Zusteigeort, its identifier is returned to the memory so that it is again assigned as soon as all the identifiers stored back before it have been assigned. If the memory is executed as FIFO memory, the sequence "1", "2", "3" is cyclically repeated (or "AI", "A2", "A3", etc.), however, each elevator car will be displayed on the display of a particular location by the same identifier until it has reached or left that location, one by the initial occupancy of the FIFO memory presettable order de The identifier thus advantageously remains.

Preferably, the displays associated with each of the floors indicate the position of one or more elevator cars to which an identifier has been assigned for a stop on the associated floor. This can be done, for example, by displaying the identifiers associated with the arriving elevator cars in addition to a series of display elements depicting the floor positions. This improves For the elevator users, the overview of the elevator system, since now not only the order of the incoming elevator cars, but also of them still zurückzulegende way is known. A user can thus better estimate the waiting time until the arrival of "his" elevator car.

If the elevator cars are traveling upwards in a first elevator shaft and downwards in a second elevator shaft, an elevator car can already be displayed by an indicator assigned to one elevator shaft while the elevator car is still in the other elevator shaft. The position of such an elevator car can be either realistic, i. be displayed with in the opposite direction to the direction of travel of the elevator cars in the elevator shaft changing positions, or simplified, for example by static display elements, which are arranged before a first or after a last floor position indicator of a hoistway.

In a display device according to the present invention, the storage capacity of the memory may be less than the number of elevator cars maximally moving in an elevator shaft. As a rule, not all lift cabins that pass through a particular slip point also stop at this slip point. The non-persistent cabins do not need to be assigned identifiers for these locations, so the storage capacity of the storage can be reduced.

In a method for communication with an elevator system according to the present invention, a user is notified of the identifier of an elevator car carrying out his transport order in response to his destination call and displayed in a display associated with a delivery location before that elevator car arrives there and as long as it is available there. The destination call may be, for example, the user entering a desired destination floor, a specific room (for example, his room number), a specific destination (for example "hotel swimming pool") or a visitor (who is assigned to her office) or the like by means of an alphanumeric keyboard, voice recognition, touch screen. Pad, or the like to a destination station, a

Issue card reader, a mobile phone or the like or by wearing or activating a transmitter such as a hotel room key or ID card. The elevator control indicates the transport order, which apart from the destination also the starting point, For example, the floor in which the destination call was issued, may include a prioritization of the user and the like, according to certain criteria of a particular elevator car to.

An identifier manager assigns this elevator car for the Zusteigeort an individual identifier that is communicated to the user: For this purpose, the assigned identifier can be issued visually and / or acoustically, for example, at the destination station or the card reader or displayed on the mobile phone of the user.

The identifier is displayed at the delivery location when this elevator car is ready there. As a result, the user recognizes that this elevator car will execute its transport order and rises.

According to one embodiment of the present invention, the identifiers associated with a dispatch location are cyclically assigned to the elevator cars, preferably in the order in which they arrive and are available there. If a total of n identifiers are available, for example the natural numbers 1, 2,... N, then the first elevator car provided at the forwarding location is the identifier 1, the second elevator car is the identifier 2 and the nth elevator car is the identifier n allocated. The (n + 1) th elevator car is again assigned the identifier 1, the (n + 2) th elevator car the identifier 2 and so on.

According to the invention, several designators associated with a posting location are displayed simultaneously. Advantageously, the number of possible identifiers is greater than or equal to the number of identifiers selected, which are output as a maximum on the Zusteigeort associated display. If the number of possible identifiers corresponds to the number of maximum displayed ones, the memory space can be minimized. If the number of possible identifiers is greater than the number of identifiers maximally displayed, the identifier of an elevator car which has just left the submission location does not immediately appear as an identifier for the elevator car newly added to the display, so that the clarity of the display is improved.

Of course, even multiple users on a floor, their destination floors are identical or differ from each other, but can be reconciled with each other, be assigned the same elevator car. If, therefore, an identifier manager has already allocated a temporary identifier for a certain forwarding address as a result of a destination call of a first user of an elevator car and issued it to the first user, and the elevator control assigns the same elevator car to a second user in the same floor on the basis of whose destination call this is already issued identifiers also issued to this second user so that he uses the same elevator car.

For example, when a first user on the first floor calls an elevator to go to the third floor, an elevator car is assigned to this first user by the elevator controller, temporarily assigned to this elevator car by the first floor identifier manager the identifier "U2" and this identifier If a second user on the first floor calls an elevator to move to the second floor, the same elevator car is assigned to him by the elevator control, which was temporarily assigned the identifier "U2" by the identifier for the first floor. Accordingly, this identifier is also output to the second user. When a third user on the first floor calls an elevator to also drive to the third floor, the same elevator car assigned by the first level identifier manager to the identifier "U2" is assigned to him by the elevator control third user spent.

When this elevator car approaches or is ready for the first floor, the display displays this identifier "U2." From this display, both the first and second and third users recognize that this elevator car is serving their transport order and climbing The elevator car then sequentially moves to the second and third floors.

Other objects, advantages and features will become apparent from the dependent claims and the following embodiments. This shows, partially schematized:

1 shows a partial section through an elevator system with a display device according to an embodiment of the present invention in a first state. Figures 2A-2C are each a display of the elevator system of Figure 1, which is associated with a Zusteigeort.

Fig. 3 is a partial section through the elevator system of FIG. 1 in a second

Status; and FIGS. 4A-4C show a representation corresponding to FIGS. 2A-2C in a second state.

In Fig. 1, partially schematically, an elevator shaft 1.1 of an elevator system is shown in which elevator cabins 2.1-2.4 between floors 3, of which only the second to tenth floor 3.2-3.10 are shown, can move upwards autonomously. As indicated in Fig. 1, next to the elevator shaft 1.1, a further elevator shaft 1.2, which is preferably used for the downward movement of the elevator cars, and other elevator shafts, not shown, may be arranged. The elevator shafts 1 are not necessarily structurally separated from each other, but may for example be defined by guide rails for the elevator cars 2. The invention is explained below with reference to an elevator shaft 1.1, in which the elevator cars 2 only move upwards. The explanations also apply correspondingly to elevator shaft 1.2 in which the elevator cars only move downwards, and to elevator shafts (not shown) in which elevator cars can move both up and down autonomously. Also, the direction of movement in elevator shaft 1.1 and / or 1.2 can be reversed to provide, for example, at the beginning or end of a working day a higher transport capacity in the upward or downward direction available.

The elevator shaft 1.1 has on each floor an elevator shaft door 4, which forms a Zusteigeort. Above each hoistway door 4, a display 5 of the display device according to an embodiment of the present invention is arranged so that a user uniquely associates this display with the hoistway door located thereunder. FIGS. 2A-2C show, by way of example, the displays 5.60, 5.70 and 5.100 associated with elevator shaft doors 4.6, 4.7 and 4.10 in the sixth, seventh and tenth floor values 3.6, 3.7 and 3.10, respectively. The displays, not shown, for the remaining elevator shaft doors 4 to the elevator shaft 1.1 and the elevator shaft doors to the other elevator shafts are of identical construction.

Each display 5 comprises a floor strip 5.il and a position bar 5.12, where i = l, 2, ... denotes the floor.

In a first state shown in Fig. 1, the car 2.4 holds in the second and the cabin 2.3 on the fourth floor, while the cabins 2.2, 2.1 are moving straight from the sixth to the seventh and from the eighth to the ninth floor. In floor 3.6, two user groups have set down destination calls, in floors 3.7 and 3.10 three user groups each. As a user group, one or more persons are designated whose starting floor is identical and which are assigned to the same elevator car.

For this purpose, users have, for example, on the floor on which they want to board, entered their destination via a keyboard in the area of Zusteigeorte or sent via a mobile phone to a recipient. Alternatively or additionally, the users can also enter their destination via a destination dialing device assigned to the floor, which is not arranged directly in the area of the boarding locations. A central elevator controller (not shown) assigns the elevator cars 2 to the transport requests resulting from the destination calls according to predetermined criteria (for example, shortest waiting time for all users). An example of such assignments is shown in the following table:

After the central elevator control has assigned an elevator car 2 to a user group, an identifier manager of an elevator car 2 assigned to a location 4 with a display device 5 according to the invention assigns a temporary identifier to which it can refer to a memory, for example a FIFO memory.

In the first state shown in FIG. 1 and in the table, for example, in the sixth floor 3.6 the elevator car 2.3 was first assigned to the user group "1", then the elevator car 2.4 to the user group "2". Accordingly, the identifier manager for the floor 3.6 with the hoistway door 4.6 removes its memory first the identifier "AI" and temporarily assigns it to the elevator car 2.3, then it removes its memory from the following identifier "A2" and temporarily allocates it to the elevator car 2.4.

Similarly, an identifier manager, which is associated with the floor 3.7 with the hoistway door 4.7, first removes the identifier "AI" from its memory and temporarily allocates it to the elevator car 2.2, which was first assigned a transport order for the seventh floor, then removes it Memory the following identifier "A2" and temporarily assigns it to the elevator car 2.3, and finally it takes its memory the following identifier "A3" and temporarily assigns this to the elevator car 2.4, which was last assigned a transport order for the seventh floor.

An identifier manager associated with hoistway door 4.10 operates in an analogous manner to result in subsequent allocation of stall-specific temporary identifiers to the elevator cars:

As can be seen clearly from this, the same elevator car (for example, car 2.3) is assigned a different identifier each time by the identifier managers who are assigned to the pickup locations 4.6, 4.7 and 4.10 on the floors 3.6, 3.7 and 3.10. This is not a problem because the elevator car only on the floor 3 must be clearly identifiable. It also appears from the table that elevator cars which have not been assigned a transport order for the floor in question and which therefore do not need to be identified on this floor are not assigned an identifier. If such an elevator car, to which no identifier has been assigned in order to let users exit, then the missing display of an identifier signals that this elevator car is not intended for a transport order originating from this floor. However, in order to prevent confusion or misinterpretation of the lack of display as the user's failure to display, an identifier manager may also assign an identifier to those elevator cars whose transport request ends at the dispatch location associated with the identifier manager.

As can also be seen from the above table, a maximum of three elevator cars are assigned identifiers per elevator shaft by one identifier manager. Accordingly, the memories include three memory locations pre-assigned with the designators "AI", A2 "and" A3 "in this order.

The designators assigned to the individual elevator cars are output on the display 5 associated with the location 4, in accordance with the position of the elevator car to which they are assigned. For this purpose, the identifiers "AI", "A2" and "A3" on the position bar 5.i2 light up at the corresponding position below the floor strip 5.sl, as shown in FIGS. 2A-2C. i2 permanently as long as the associated elevator car approaches the respective forwarding location and begins to flash as soon as the elevator car initiates the braking process, which particularly clearly signals the elevator car currently arriving, in particular if a user does not know which floor it is on and mere position indication that an elevator car is on its floor would be of little significance to him.

Fig. 3 shows a second state, which temporally follows the first state described above. Figures 4A-C, in similar fashion in Figures 2A-C, show the displays associated with hoistway doors 4.6 (Figures 4A), 4.7 (Figures 4B) and 4.10 (Figure 4C), respectively.

In the second state, Cabin 2.1 has just operated the tenth floor 3.10 and left this. Accordingly, the associated identifier manager has returned the identifier "AI" assigned to the car 2.1 to its memory and deleted it from the display 5100. For example, if a destination call on the tenth floor is now assigned to the elevator car 2.4, the identifier manager will remove for the submission location 4.10 the next Identifier from his store. Since the memory has only three memory locations, the identifier "AI" currently being supplied is next extracted and now assigned to the elevator car 2.4 (see Fig. 4C).

Similarly, the identifier manager associated with the resort location 4.7 deletes the identifier "AI" from the display 5.7 as soon as cabin 2.2 leaves the seventh floor and returns it to its storage.

As is particularly clear hereby, the temporary identifiers allocated with respect to one respective transfer location remain assigned until the designated elevator cars have left the transfer location. The elevator car 2.3, for example, in the second state on the seventh floor continues to be referred to as "A2", although no "AI" is present.

Thus, the identifiers "AI", A2 "and" A3 ", as can be seen in particular on the display 5.100 in FIGS. 2C and 4C, are cyclically assigned to the elevator cars:

Elevator cabin with transport order 2.1 2.2 2.3 2.4

Identifier A1 A2 A3 A1 A2 A3

Accordingly, the identifier managers can be formed very easily and reliably, their memories requiring only a small capacity. The individual identifier managers and their memory can be implemented equally by independent systems assigned to the respective ports 4, by a system for an entire floor 3 or in a central elevator control. Accordingly, according to the present invention, a central display device may, for example, be implemented in the central elevator control and comprise the individual displays 5 associated with the respective ports 4. Alternatively, the central elevator controller may communicate with standalone display devices, each associated with a location 4.

A method of communication with the elevator system described above An embodiment of the present invention now proceeds as follows:

A user first issues a destination call. For this he gives, for example, his destination via a keyboard, which is centrally located for all Zusteigeorte on a floor. For example, in the first state of FIG. 1, a user entered the 11th floor as the destination on the seventh floor 3.7.

The central elevator control registers this destination call and assigns a corresponding transport order to an elevator car 2. In the first state according to FIG. 1, the transport order has been assigned, for example, to the elevator car 2.3, since the elevator car 2.2, which previously stopped on the seventh floor, should travel quickly and without stopping on the 11th floor to the 15th floor.

As soon as elevator car 2.3 has been assigned the seventh-floor transfer order, the identifier manager for submission 4.7 of this car temporarily allocates the next identifier from its memory. Since the identifier "AI" has already been taken and assigned to cabin 2.2, the next identifier "A2" is now removed and assigned to the elevator car 2.3 temporarily.

This identifier "A2" is communicated to the user in response to his destination call on a display next to the keypad for the destination call input.

As soon as the elevator car 2.3 is one of the next three elevator cars approaching the stop location 4.7 and stopping there, its identifier "A2" is displayed in the position 5.70 assigned to this location 4.7 on the position bar 5.72 at the corresponding location below the floor panel 5.71 (FIG 2B) The user recognizes on this display the identifier which has been given to him and moves to the elevator shaft door 4.7.

First, Cabin 2.2 stops on the seventh floor (state between first and second state). The user recognizes at the flashing display "AI" at the floor position "7" in the display 5.70 that this car 2.2 will not carry out its transport order (since this car is passed through without stopping on the 11th floor until the 15th floor). As soon as the car 2.2 has left the seventh floor (second state, Figure 3), the identifier "AI" disappears from the display 5.70 The user can follow the position of the identifier "A2" on the position bar 5.72 relative to the floor track 5.71. how "his" elevator car 2.3, to which the identifier "A2" has been assigned, is approaching the entry location 4.7. As soon as it has reached it, the display "A2" flashes below the floor level "7" and the user steps into the elevator car 2.3, to which his transport order has been assigned.

If users also enter transport orders in the downward direction and / or drive up elevator cabins in other elevator shafts (not shown), transport orders can also be assigned to elevator cabins in other elevator shafts. Thus, for example, in a manner not shown assigned to a destination call on the seventh floor with destination sixth floor of an elevator car in the hoistway 1.2 a corresponding transport order and this elevator car assigned by an identifier manager, which is assigned to the elevator shaft 1.2 elevator shaft door on the seventh floor, an identifier , for example, "B2", which is communicated to the user and displayed on a display associated with this hoistway door when the corresponding elevator car is on the seventh floor The user recognizes "his" elevator car in an analogous manner and can recognize this due to the shaft-specific part "B" in FIG Identifier "B2" distinguish from the designated "A2" elevator car 2.3.

For this purpose, it is necessary that the identifiers assigned to the elevator cars are each assigned only once at each floor at the same time. For the elevator cars that move inside an elevator shaft and therefore the same

Zusteigeort, for example, use a hoistway door, this ensures the above-described allocation of identifiers from the memory of the Zusteigeort associated identifier manager. For elevator cabins in various elevator shafts, this can advantageously be achieved by a shaft-specific portion in the identifier, for example the aforementioned Latin capital letters "A", "B" etc.

However, the present invention is not limited thereto. Thus, for example, a shaft-specific proportion and / or a cabin-specific proportion of an identifier can be defined by any alphanumeric characters, symbols and / or colors. In the exemplary embodiment, the individual user groups, which differ in their transport orders, are each assigned their own elevator cars. Of course, this does not have to be the case. Equally, for example, the same elevator car 2.1 could be assigned to the user groups 6 and 7 in the floor 3.10.

In this case, the identifier manager of the tenth floor elevator car 2.1 temporarily assigns the identifier "AI" after the destination call has been received from the user group 6, and informs it to the user who issued the destination call User group 7 received and this transport order was assigned by the elevator control in a modification of the embodiment of the same elevator car 2.1 recognizes the identifier manager that the elevator car 2.1 for the tenth floor has already been assigned a temporary identifier.He therefore does not assign a new identifier this cabin but also informs the user from the second user group who has issued this destination call, the identifier "AI". In the same way, the same elevator car 2.1 is also allocated to other users from the first or second user group on the basis of the identity or compatibility of their transport requests, and accordingly the already assigned identifier "AI" is communicated.

Due to the display 5,100, both the users of the first and second user groups recognize that they are to enter the cabin 2.1 if they are on the tenth floor. In this modification, the elevator car 2.2 is temporarily assigned to the first destination call from the third user group 8 corresponding to the next identifier "A2".
