Abstract

The method involves controlling an elevator car by controllers (2,2',2''). A convenient call allocation is determined by target call controllers (3,3',3''), where incase the detected convenient call allocation is not fulfilled, an unallocation of the call allocation is carried out in an elevator call. An independent claim is included for a computer program product.

Description

The invention relates to a method for controlling an elevator installation according to the preamble of patent claim 1.

GB2276470A discloses a method for controlling an elevator installation. The elevator system includes several elevators with their own controls per elevator. A group control is superior to the controls of the elevators. While each control of an elevator drives an elevator drive and a door drive and thus moves an elevator car and opens and closes an elevator door, in a first step the group control sets up a batch call assignment for a plurality of floor calls and determines in a second step from this batch Call assignment using multiple optimization rules optimal call assignment. One of these optimization rules is the adherence to a given standard waiting time, ie the individual waiting times of the passengers should not exceed the standard waiting time. Another optimization rule is the prioritization of a particular passenger, ie this passenger is served very quickly by the elevator system. The optimal call assignment is implemented by the controls of the elevators.

Traditionally, in a landing call, an elevator car is first moved to the floor of the call input. Only after the passenger has entered the elevator car is a car call placed on a destination floor and the elevator car moved to this destination floor. In the case of a destination call, on the other hand, a designation of a desired destination floor already takes place when the call is entered, so that no more cabin calls are necessary. Thus, the destination call control already knows about the Call input the destination floor and can therefore optimize not only the approach of the call input floor but also that of the destination floor.

EP0891291A1 discloses another method for controlling an elevator installation, in which the controls of the individual elevators are destination call controls, and all destination call controls are combined into a common group control. For a destination call, the group control selects the cheapest elevator from all relevant elevators.

WO2007 / 130009A discloses an elevator system for carrying large articles. A passenger can enter on a destination call device that he is traveling with a large article. For this purpose, the system provides a call allocation to a cabin, which should have sufficient space for the article.

GB2216683A discloses an elevator system that conveys status from a first elevator car to a waiting passenger. If the passenger is not satisfied with the first elevator car, the passenger may request a second elevator car.

JP2002120976A discloses an elevator system for disabled passengers. The system communicates via a mobile phone.

EP0443188A discloses a method and apparatus for destination call allocation in elevator groups. Operating costs and variable bonus / penalty factors are used.

EP1880965A discloses an elevator system for disabled and non-disabled passengers. The system may allow or prohibit the cancellation of a car call.

The object of the present invention is to further develop these methods.

This object is achieved by the invention according to the definition of the characterizing features of independent claim 1.

In the inventive method for controlling an elevator installation with at least one elevator car, the elevator car is controlled by at least one control. At least one destination call control determines at least one cheapest call allocation for at least one destination call. If the determined most favorable call allocation does not fulfill at least one passenger-specific option, a non-allocation of the most favorable call allocation to an elevator car is made.

This has the advantage that a favorable call allocation is only assigned to the elevator car, if a passenger-specific option can also be guaranteed fulfilled. Suboptimal call allocations are thus avoided. Especially at peak times, an elevator system can reach its capacity limit. By avoiding suboptimal call allocation, the expectation of a passenger to the performance elevator system is not disappointed.

Advantageous developments of the invention are described in the dependent claims.

Advantageously, at least one most favorable call allocation is determined by the destination call control for the destination call and for at least one lift-station-specific parameter using at least one situation-specific parameter.

This has the advantage that, when determining the most favorable call allocation, the destination call and an elevator-specific parameter are specified as starting conditions and at least one situation-specific parameter is considered as a secondary condition.

Advantageously, at least a number of the elevator cars or at least one transport capacity of an elevator car or at least one equipment of an elevator car or at least one speed of an elevator car are used as elevator-specific parameters. Advantageously, the equipment of an elevator car refers to an elevator car with panoramic view or an elevator car with multimedia equipment or a particularly spacious elevator car or a particularly fast-moving elevator car or an elevator car with a particularly wide or large landing door or an elevator car with particularly fast schliessender / opening floor door or an elevator car that holds particularly well in one floor or an elevator car that is particularly quiet or an elevator car with an especially large number of floor doors or that uses an elevator car with an additional authentication device. Advantageously, the situation-specific parameter is at least one instantaneous transport volume of the elevator installation or at least one instantaneous distance away of a passenger from a lift cage.

This has the advantage that so a variety of aforementioned equipment a lift cage is specifically taken into account for the fulfillment of the passenger-specific option.

Advantageously, the destination call controller compares whether the determined favorable call allocation fulfills at least one passenger-specific option set as a secondary condition. Advantageously, the destination call controller compares whether the ascertained most favorable call allocation satisfies all passenger-specific options set as constraints.

This has the advantage that one or more passenger-specific option (s) is / are set as a secondary condition and can therefore be taken into account separately from given parameters of the elevator installation or from rapidly changing situations in the transport volume.

At least one waiting time or at least one destination time or at least one change of direction number or at least one transfer number or at least one intermediate number or at least one elevator car passenger number or at least one route distance or at least one way passenger number or at least one passenger pass number is advantageously used as a passenger-specific option an elevator cabin equipment or at least one start floor change number or at least one destination floor change number used.

This has the advantage that a large number of individual passenger-specific options can be taken into account, which are very different.

Advantageously, it is estimated by the destination call control whether the passenger-specific option can be fulfilled when determining the most favorable call allocation. If the estimate shows that at least one passenger-specific option can not be met when determining the most favorable call allocation, a Non-allocation of the cheapest call allocation made to an elevator car.

This has the advantage that it can be estimated before determining a favorable call allocation, whether a cheapest call allocation should be determined at all, so that in negative estimation no determination of a cheap call allocation is necessary, which saves resources and time and thus is cost.

Advantageously, if the estimate is that at least one passenger-specific option can be satisfied when determining the most favorable call allocation, the destination call controller determines at least one most favorable call allocation using at least one situation-specific parameter for the destination call and for at least one elevator-specific parameter.

This has the advantage that the determination of a favorable call allocation takes place only with a positive estimate, which saves resources and time and is therefore cost-effective.

At least one second least expensive call allocation is advantageously determined by the destination call controller for at least one elevator-specific parameter using at least one changed destination call or at least one changed passenger-specific option or at least one changed situation-specific parameter.

This has the advantage that a second least expensive call allocation is determined as a change of the most favorable call allocation. In the process, the destination call or a passenger-specific option or a situation-specific parameter is specifically changed.

Advantageously, the passenger-specific option or the changed passenger-specific option is met by the second-lowest call allocation.

This has the advantage that the change is a targeted requirement to fulfill the existing passenger-specific option or the modified passenger-specific option.

Advantageously, the destination call controller generates a modified passenger-specific option by lowering the quality rank of the passenger-specific option. Advantageously, a modified passenger-specific option with a comparison with the unchanged passenger-specific option longer waiting time or longer destination time or greater change of direction or larger transfer number or larger intermediate number or larger elevator car passenger number or further distance or distance greater route passenger or less luxurious elevator cabin equipment or larger number of start stock exchanges or larger number of destination stock exchanges.

This has the advantage that the second best call allocation for the passenger is understandable and easy to understand.

Advantageously, the destination call control generates an altered destination call by lowering the quality rank of at least one start floor change number or at least one destination floor change number of the destination call.

This has the advantage that the destination call itself, ie the call input floor and the destination floor, are changed in order to obtain a second best call allocation.

Advantageously, the destination call control waits until at least one situation-specific parameter changes. Advantageously, as modified situation-specific parameters, at least one lower instantaneous transport volume of the elevator installation or at least one shorter instantaneous distance away from a passenger to an elevator cabin is used.

This has the advantage that with rapidly changing arrival rates of passengers often a short wait is worthwhile to improve the situation.

Advantageously, a plurality of favorable call allocations are determined for the destination call or for a changed destination call and for at least one elevator-specific parameter using at least one situation-specific parameter or at least one changed situation-specific parameter. The destination call controller compares whether the determined most favorable call allocations fulfill at least one passenger-specific option set as a secondary condition or at least one changed passenger-specific option set as a secondary condition. Advantageously, the destination call control compares whether the ascertained most favorable call allocations fulfill all the passenger-specific options set as a secondary condition or all changed passenger-specific options set as a secondary condition.

This has the advantage that as soon as there is a destination call, several variations of the most favorable call allocations are determined, wherein in each case at least one of the initial conditions or at least one secondary condition is changed. Although this requires more resources and time, but offers the opportunity to give the passenger a selection of cheapest call allocations.

Advantageously, a call allocation is made to an elevator installation with several elevator cars.

This has the advantage that there is a larger selection of elevator cars or that a more flexible call allocation can be made. Especially in large buildings and at peak times can thus operate from a main floor of several elevator cars different building areas simultaneously.

Advantageously, the identification code with the address of the call input device to which the identification code was sent is transmitted to the destination call control or the identification code with the address of the mobile device is sent to the destination call control. Advantageously, the destination call control transmits at least one destination call acknowledgment signal to the address of the call input device to which the identification code has been sent, or at least one destination call acknowledgment signal is sent to the address of the mobile device from which the identification code was sent.

This has the advantage that the passenger receives a feedback from the destination call control in response to an identification code.

Advantageously, a determined most favorable call allocation is output as at least one destination call acknowledgment signal on at least one output device of the call input device or on at least one input / output device of the mobile device.

The call input floor is the floor S1 to S9 on which the call input device 4 is located in the building, or the floor S1 to S9, from which the mobile device 5 communicates with the destination call control 3, 3 ', 3 "The desired destination floor is that of the passenger desired destination floor.

• Die Wartezeit ist die Zeit zwischen Zielruf-Eingabe und Öffnen der Stockwerktür bei Ankunft der Aufzugskabine 1, 1', 1" auf dem Startstockwerk. Für eine Very Important Person (VIP) liegt eine VIP-Wartezeit bei fünfzehn Sekunden. Für eine Important Person (IP) liegt eine IP-Wartezeit bei 30 Sekunden. Für Standard Person (SP) liegt eine SP-Wartezeit bei 45 Sekunden.
• Die Zielzeit ist die Zeit zwischen Zielruf-Eingabe und Öffnen der Stockwerktür bei Ankunft der Aufzugskabine 1, 1', 1" auf dem Zielstockwerk. Eine VIP-Zielzeit liegt bei 45 Sekunden. Eine IP-Zielzeit liegt bei 90 Sekunden. Eine SP-Zielzeit liegt bei 150 Sekunden.

According to Fig. 5 to 7 In step A2, at least one passenger-specific option T2 such as waiting time, destination time, direction change number, transfer number, intermediate stop number, elevator car passenger number, route distance, route passenger number, elevator cabin equipment, start floor change number, destination floor change number, etc. is set as a secondary condition. Depending on the prioritization of the passenger, the passenger-specific options in the quality rank are different. For a medium-sized building with about 30 storeys, the passenger-specific options T2 are defined as follows:

• The waiting time is the time between the destination call entry and the opening of the landing door upon arrival of the elevator car 1, 1 ', 1 "on the starting floor. For a Very Important Person (VIP), a VIP waiting time is fifteen seconds. IP) there is an IP waiting time of 30 seconds, for standard person (SP) an SP waiting time is 45 seconds.
• The target time is the time between destination call entry and opening of the landing door upon arrival of the elevator car 1, 1 ', 1 "on the destination floor A VIP target time is 45 seconds An IP target time is 90 seconds An SP target time is 150 seconds.

The change of direction number is the number of changes in direction of the elevator car 1, 1 ', 1 "during the journey from the start floor to the destination floor A VIP change of direction number is 0. An IP direction change number is 0. An SP direction change number is one.

The transfer number is the number of changes between elevator cars 1, 1 ', 1 "in order to be moved from the start floor to the destination floor A VIP transfer number is zero An IP transfer number is one An SP transfer rate is two.

The intermediate stop number is the number of floor stops of the elevator car 1, 1 ', 1 "during the journey from the start floor to the destination floor A VIP intermediate stop number is zero, which corresponds to a direct drive ,

The elevator car passenger number is the maximum permissible number of passengers in the elevator car 1, 1 ', 1 "during the journey from the start floor to the destination floor A VIP elevator car passenger number is 20% of the transport capacity of the elevator car 1, 1', 1" , An IP elevator car passenger number is 80% of the transport capacity of the elevator car 1, 1 ', 1 ". An SP elevator car passenger number is 100% of the transport capacity of the elevator car 1, 1', 1".

The path distance is the distance from the location coordinate of the call input device 4 or the mobile device 5 to the elevator installation and from there to a destination. The destination can be predefined, for example, a specific building door 9 on the destination floor. The predefined destination is stored in the passenger profile together with the destination call and the passenger-specific option T2 and can be read out and / or transmitted just like the latter. The destination can also be entered on the input device 41 of the call input device 4 or on the input / output device 51, 52 of the mobile device 5 and transmitted exactly as an input destination T1 or a read identification code to the destination call control 3, 3 ', 3 " A VIP route distance is as short as possible both on the call input floor and on the destination floor: IP route distance is as short as possible only on the call input floor or on the destination floor.

The way passenger number is the number of other passengers on the way from the location coordinate of the call input device 4 and the mobile device 5 to the elevator installation and from there to the destination. For this purpose, the destination call control 3, 3 ', 3 "has frequencies of use on the paths of the building.The frequencies of use can vary depending on the time of day and the day of the week or public holiday.A VIP way passenger number is as low as possible both on the call input floor and on the destination floor An IP-way passenger number is as small as possible only on the call input floor or on the destination floor, and an SP-way passenger number is not so optimized in frequency of use.

The lift cage equipment indicates the equipment of an elevator car 1, 1 ', 1 "during the journey from the start floor to the destination floor A VIP lift cage equipment defines a specific, luxuriously or originally equipped lift cage 1, 1', 1". Thus, a VIP elevator car equipment can be a panoramic elevator car or an elevator car 1, 1 ', 1 "with multimedia equipment such as audio, video, etc. or an especially large elevator car 1, 1', 1" or an especially fast-moving elevator car 1, 1 ', 1 "or an elevator car 1, 1', 1" with a particularly wide or large landing door or an elevator car 1, 1 ', 1 "with a particularly fast closing / opening floor door or an elevator car 1, 1 ', 1 "with additional authentication device such as an iris scanner, fingerprint scanner, body scanner, etc. An IP elevator car equipment defines, for example, an elevator car 1, 1 ', 1 ", which holds particularly precisely in the floor S1 to S9, or an elevator car 1, 1', 1" or an elevator car 1, 1 ', 1 "which drives with particularly low noise An SP elevator car equipment defines an elevator car 1, 1 ', 1 "equipped according to the usual expectations.

The starting floor change number is the number of floors between the passenger's call input floor and the starting floor, from which the travel with the elevator car 1, A VIP start floor change number is zero, ie the travel of the elevator car 1, 1 ', 1 "begins on the call input floor. An IP start floor change number is one, ie call input floor and start floor can differ by +/- one floor. An SP start floor change number is two, ie call input floor and start floor can differ by +/- two floors.

The destination floor change number is the number of floors between the destination floor desired by the passenger according to the destination call and the destination floor of the journey with the elevator car 1, 1 ', 1. "A VIP destination floor change number is zero, ie the destination floor according to destination call corresponds to the actual destination floor at the end of the Drive the elevator car 1, 1 ', 1 ". An IP destination floor change number is one, ie the destination floor according to the destination call and the actual destination floor can differ by +/- one floor. A SP target floor change number is two, ie the destination floor according to the destination call and the actual destination floor may differ by + / two floors.

The described three-stage differentiation of the passenger-specific option T2 is exemplary and can of course also less than three stages, for example two stages or more than three stages, for example, five stages or continuously, for example, divided into second sections to be realized. Thus, the direction change number can be varied in three stages between a first direction change number zero and a second direction change number two. Thus, the elevator car passenger number can be varied in five stages in five 20% sections. Thus, the waiting time or the target time can be varied in seconds between a minimum and a maximum.

The passenger-specific option T2 is stored in at least one passenger profile and can be stored in a computer-readable data memory of the destination call control 3, 3 ', 3 "or the call input device 4 or in the mobile device 5 be. For example, the passenger-specific option T2 is read out during the call input of a destination call and transmitted together with the destination call from the call input device 4 or from the mobile device 5 to the destination call control 3, 3 ', 3 " Destination call control 3, 3 ', 3 "store and read when assigning an identification code to a destination call. For example, for each passenger with a mobile device 5 with identification code, there is a passenger profile which passenger profile has at least one predefined destination call T1 and at least one passenger-specific option T2. The passenger profile is generated by at least one building management and customized for each passenger. It is the building management, which arranges a division of passengers into VIP, IP and SP. The passenger or the destination call control 3, 3 ', 3 "can change a passenger-specific option T2, thus lowering or increasing a quality-ranked passenger-specific option T2 The reduction in the quality rank of the passenger-specific option T2 corresponds to a modified passenger-specific option T2 'and takes place, for example, by the passenger's confirmation of a corresponding second-best call allocation T4', conversely also an increase in the quality ranking of a passenger-specific option T2, if the elevator installation is not within the capacity limit and if the fulfillment of a passenger-specific option T2 increased in terms of quality can also be guaranteed Specific option T2 is carried out, for example, by confirming a corresponding most favorable call allocation T4 by the passenger. Several passenger-specific options T2 can be weighted, ie a passenger-specific option T2 can preferably be set or read out or transmitted. For example, the building management or the passenger sets a passenger profile Weighting of several passenger-specific options T2. Of course, this weighting can also be changed. The passenger-specific option T2 is output to the passenger as multimedia information that is part of the destination call acknowledgment signal. Thus, the passenger inputting a destination call T1 at the call input device 4 or sending an identification code is outputted as multimedia information a direction change number or a destination time of the transportation with the elevator car. The multimedia information may include a written text, a graphic, but also a spoken word and sentence and a video picture. Thus, the target time can be output as expiring time. With knowledge of the present invention, the skilled person can realize further passenger-specific options.

The elevator installation has at least one elevator-specific parameter such as the number of elevator cars 1, 1 ', 1 ", the transport capacity of an elevator car 1, 1', 1", the equipment of an elevator car 1, 1 ', 1 ", the speed of an elevator car 1, 1 ', 1 ", etc. on. The equipment of the elevator car 1, 1 ', 1 "with panoramic view of the building or in a courtyard of the building or an elevator car 1, 1', 1" with multimedia equipment such as audio, video, etc. or a particularly large amount of space offering elevator car 1, 1 ', 1 "or a particularly fast-moving elevator car 1, 1', 1" or an elevator car 1, 1 ', 1 "with a particularly wide or large landing door or an elevator car 1, 1', 1 "with an especially fast closing / opening landing door or an elevator car 1, 1 ', 1" or a particularly quietly moving elevator car 1, 1', 1 "or an elevator car 1, 1 'which holds particularly well in the floor S1 to S9. , 1 "with particularly many floor doors or an elevator car 1, 1 ', 1" with additional authentication device such as an iris scanner, fingerprint scanner, body scanner, etc. include.

According to Fig. 5 to 7 At least one situation-specific parameter T3, such as an instantaneous transport volume of the elevator installation, an instantaneous route distance of a passenger to an elevator car 1, 1 ', 1 ", etc., is taken into account in a step A3 It is also desirable to provide an elevator car 1, 1 ', 1 "on the start floor only at the time at which the passenger who is to be moved in the building according to the destination call T1 actually drives the elevator car 1 , 1 ', 1 "has reached.

The situation-specific parameter T3 is output to the passenger as multimedia information that is part of the destination call acknowledgment signal. Thus, the passenger is output as a multimedia information a current Wegentfernung. The path distance can be effected as a permanently updated distance specification, for example, the remaining distance from the current location coordinate to the elevator car 1, 1 ', 1 "in meters is output. [Bei Bei] With knowledge of the present invention, the person skilled in the art can realize further situation-specific parameters.

According to Fig. 5 to 7 In a step A4, the determination of at least one most favorable call allocation T4 is carried out for the unchanged destination call T1 and for the unchanged elevator-specific parameter using the unchanged situation-specific parameter T3.

In addition, according to Fig. 5 in a step A5, a comparison is made as to whether the determined favorable call allocation T4 fulfills the unchanged conditioner-specific option T2 set as a secondary condition. The steps A4 and A5 can take place at the same time or with a time delay.

According to Fig. 5 If fulfillment T5 of the unchanged passenger-specific option T2 for the most favorable call allocation T4, a destination call acknowledgment signal is generated in a step A6. For example Passengers are offered several possible cheapest call allocations T4, which differ in the unchanged passenger-specific option T2. Thus, the passenger can select whether he wants a cheapest call allocations T4 optimally with respect to an unchanged passenger-specific option T2 waiting time, finish time, direction change number, transfer number, intermediate number, elevator car passenger number, route distance, way passenger number, elevator cabin equipment, start floor change number, destination floor change number, etc. is.

The plurality of possible most favorable call allocations T4 are output with at least one multimedia information on the output device 42 of the call input device 4 or on the input / output device 51, 52 of the mobile device 5. The multimedia information indicates to the passenger which cheapest call allocation T4 is optimal with respect to which unchanged passenger-specific option T2. For example, a first most favorable call allocation T4 is optimal with respect to the waiting time, while another most favorable call allocation T4 is optimal with respect to the transfer time.

According to Fig. 5 If at least T5 'of the unchanged passenger-specific option T2 is not met, at least one change T7 is generated in a step A7. According to Fig. 6 At least one change 7 is generated for the destination call T1 or at least one unaltered passenger-specific option T2 or situation-specific parameter T3. The change T7 starts the generation of at least one changed destination call T1 'or starts the generation of at least one changed passenger-specific option T2' or starts the waiting for at least one situation-specific parameter T3 'to change. The change T7 is thus a targeted specification for the determination of a second least expensive call allocation T4 ', for which the passenger-specific option T2 or a modified passenger-specific option T2' can be guaranteed.

According to Fig. 5 to 7 At least one modified destination call T1 'is generated in a step A1'. The changed destination call T1 'has, for example, another call input floor or another destination floor. A modified destination call T1 'is generated in accordance with the passenger-specific option T2 start floor change number or destination floor change number. That is, for a VIP, the changed destination call T1 'can not be generated without previous change of the passenger-specific option T2 start floor change number or destination floor change number. For an IP or SP, however, the modified destination call T1 'can be generated by lowering the quality rank of the passenger-specific option T2 start floor change number or destination floor change number.

According to Fig. 5 to 7 At least one modified passenger-specific option T2 'is generated in a step A2'. For example, a waiting time is changed from an IP waiting time to an SP waiting time, so the passenger has to wait longer. For example, a target time is changed from a VIP target time to an IP target time, so the passenger needs more time to reach the target. For example, a direction change number is changed from a VIP direction change number to an IP direction change number, so the passenger must change the direction of travel when driving to the destination floor. For example, a transfer number is changed from an IP transfer number to an SP transfer number, so the passenger has to change frequently. For example, an intermediate stop number is changed from a VIP intermediate stop number to an SP intermediate stop number, so on the journey to the destination floor, the elevator car 1, 1 ', 1 "of the passenger inserts more intermediate stops, for example, an elevator car passenger number from an IP elevator car Passenger number changed into an SP passenger number, the passenger is thus in a fuller elevator car 1, 1 ', 1 "promoted. For example, a VIP route distance is changed to an IP route distance, so the passenger will have to travel another route to the destination. For example, a way passenger number becomes an IP way passenger number changed into a SP-way passenger number, so the passenger will encounter more passengers on his way to the destination. For example, an elevator car equipment is changed from a VIP elevator car equipment to an IP elevator car equipment, so the passenger is carried in a less luxurious elevator car 1, 1 ', 1 "For example, a start floor change number is changed from a VIP start floor change number to an IP start floor change number , the drive of the elevator car 1, 1 ', 1 "may therefore start from a different starting from the call input floor start floor. For example, a destination floor change number is changed from a VIP destination floor change number to an IP destination floor change number, the travel of the elevator car 1, 1 ', 1 "may therefore end on a destination floor that differs from the destination floor desired according to the destination call.

According to Fig. 5 to 7 is waited in a step A3 'that changes at least one situation-specific parameter T3'. For example, it is waited until the current transport volume of the elevator installation is, for example, a few percentage points lower. For example, it waits until the momentary distance of the passenger to the elevator car 1, 1 ', 1 ", which according to destination call T1 is to be moved in the building, is shorter.

According to Fig. 5 and 7 in a step A4 'for the predetermined elevator-specific parameters, the determination of at least one second least expensive call allocation T4' using at least one modified destination call T1 'or under the constraint of at least one modified passenger-specific option T2' or for at least one changed situation-specific parameter T3 '. According to Fig. 6 For example, steps A4 and A4 'are executed at the same time as steps A4, A4'.

According to Fig. 6 is compared in a step A5 'whether several determined cheapest call allocations T4, T4' as a constraint set unchanged passenger-specific option T2 or modified passenger-specific option T2 '. The steps A4, A4 'and A5' can take place simultaneously or with a time delay.

According to Fig. 5 and 7 In a step A6 'for the second least expensive call allocation T4' a destination call acknowledgment signal is generated. According to Fig. 5 A destination call acknowledgment signal is generated in step A6 'in the event of non-fulfillment T5' of the unchanged passenger-specific option T2.

The most favorable call allocation T4 or the second least expensive call allocation T4 'is output to the passenger as a destination call acknowledgment signal on the output device 42 of the call input device 4 or on the input / output device 51, 52 of the mobile device 5. Also, a non-allocation of the cheapest call allocation T4 is issued to the passenger as a destination call acknowledgment signal. A modified passenger-specific option T2 'or a modified situation-specific parameter T3' is also output to the passenger as multimedia information.

If, therefore, due to the non-fulfillment of the passenger-specific option T2 set as a constraint, a favorable call allocation T4 is not possible, the most favorable call allocation T4 is not assigned to an elevator car 1, 1 ', 1 ". which the passenger can confirm on the input device 41 of the call input device 4 or on the input / output device 51, 52 of the mobile device 5. For example, the passenger is offered a number of possible second least expensive call allocations T4 ', which differ in the change A7 of the passenger-specific option T2 Thus, the passenger may select to make a change A7 to the passenger-specific option T2 Waiting time, Finish time, Turning number, Interchange number, Intermediate stop number, Elevator car passenger number, Route distance, Way passenger number, Elevator cabin equipment, Start floor change number, Destination floor change number, etc. would like to. This confirmation is transmitted via the same communication path as the entered destination call or the sent identification code from the call input device 4 or from the mobile device 5 to the destination call control 3, 3 ', 3 ".

The passenger has several possibilities of executing the confirmation of a favorable call allocation T4 or a second-best call allocation T4 '. For example, the passenger operates a key of the input device 41 of the call input device 4 or touches a touch screen of the input / output device 51, 52 of the mobile device 5. The computer program means of the call input device 4 is configured such that upon outputting a destination call acknowledgment signal on the output device 42, a cursor is movable over a plurality of possible most favorable call allocations T4 or over several possible second least expensive call allocations T4 '. The cursor can automatically be movable at a predetermined clock rate via the call allocations T4, T4 ', for example, the cursor lingers on each call allocation T4, T4' for one second. As soon as the passenger actuates a key of the input device 41 or touches a touch screen of the input / output device 51, 52, the movement of the cursor is stopped and the call allocation T4, T4 'over which the cursor has been stopped is confirmed. However, it is also possible for the passenger to confirm without buttons or without contact. Thus, the passenger can move the mobile device 5 embodied as RFID into or out of the range of the radio network 7 and in this way move at least one cursor on the output device 42 of the call input device 4 via call allocations T4, T4 '. The computer program means of the call input device 4 is then designed such that when issuing a destination call acknowledgment signal on the output device 42, a cursor over several call allocations T4, T4 'is movable as long as the RFID is within range of the radio network 7, and that the movement of the cursor is stopped as soon as the RFID is no longer within the range of the radio network 7. With knowledge of the present invention, of course, a reverse configuration of the computer program means is possible, ie, the cursor is movable over a plurality of call allocations T4, T4 ', as long as the RFID is out of range of the radio network 7, and the movement of the cursor is stopped as soon as the RFID is within range of the radio network 7.

According to Fig. 7 in step A8, at least one estimation is made as to whether at least one unaltered passenger-specific option T2 can be fulfilled for the destination call T1 and for the elevator-specific parameter when determining at least one most favorable call allocation T4. In the case of a positive estimation T8, the determination of a most favorable call allocation T4 follows in step A4. In the case of negative estimation T8 ', at least one change T7 is generated in step A7.

In the understanding of the present invention, the conjunction "or" used in the sense of "and / or".
