DETAILED DESCRIPTION

(8) The illustration in FIG. 1 shows schematically and in simplified form an elevator installation 10 in a building, which is not itself shown, with at least one elevator car 14 movable in at least one elevator shaft 12 and an elevator control device 16 provided at a central point of the building. The elevator control device 16 is provided in a mode and manner known per se for control of the elevator installation 10. The or each elevator car 14 is movable in a mode and manner known per se in the elevator shaft 12 or in the respective elevator shaft 12 so that different floors 18 of the building are reachable.

(9) Different control panels 20, 22, namely at least one car control panel 20 as well as a respective control panel on each floor 18 (floor control panel 22), are usually provided for a user of the elevator installation 10. The user of the elevator installation 10 communicates a respective travel request to the elevator control device 16 in the course of control actions at a control panel 20, 22 and, as soon as the travel request can be fulfilled, the elevator control device 16 causes corresponding movement of the elevator car 14.

(10) With the increasing spread of mobile radios of all kinds, particularly so-called smartphones, netbooks, tablet computers, etc., which in the following are termed mobile radios in summary and without waiver of a wider generality, there is a wish for a user of an elevator installation 10 to be able to trigger floor and car calls even without use of normal control panels 20, 22 and instead thereof by means of his or her mobile radio 24 (FIG. 2).

(11) The illustration in FIG. 2 repeats, for further description of the approach proposed here, individual aspects of the illustration in FIG. 1, so that these do not have to be described again here. The number of depicted floors 18 has been reduced in the illustration in FIG. 2 by comparison with the illustration in FIG. 1 only for reasons of clarity. In fact, the approach proposed here is not restricted to an elevator installation 10 with a specific number of floors 18. Moreover, the approach proposed here is usable even in the case of an elevator installation 10 with several elevator cars 14.

(12) Shown in the illustration in FIG. 2 is a person 23 who is designated here and in the following as user and who wishes to use an elevator car 14 of the elevator installation 10 to go from a starting floor to a destination floor. The user 23 carries a mobile telephone 24. The mobile telephone 24 is connectible in terms of communication in a mode and manner known per se with a mobile radio network as well as the internet 26 and is so connected in the case of use in the context of the approach proposed here. A connection with an external server 28, for example a server 28 of the manufacturer or the operator of the elevator installation 10, can be produced by way of the internet 26.

(13) The elevator control device 16 or a further device (not shown) connected by a line or without a line with the elevator control device 16 at the location of the elevator installation 10 is itself connected by a line or without a line with the internet 26 and by way of the internet 26 with the server 28. The following description is continued, without waiver of a wider generality, by way of the example of an elevator control device 16 connected directly with the server 28 by way of the internet 26, thus without interposition of a further device. The possibility of interposition of such a device is, however, always to be read into the following. Insofar as such a unit is present, in the case of the method hereinafter described it is present in part at the place of the elevator control device 16. The following possibilities, in particular, can be considered for the non-wired or wired connection with the internet 26: LAN, WLAN/WiFi, PSTN, 2G, 3G, LTE, GPRS, etc.

(14) After placing the elevator installation 10 in operation, at the conclusion of maintenance of the elevator installation 10 or in accordance with additional or alternative predetermined or predeterminable rules (once per day, once per month, in the event of disruptions, in the event of exchange of components, etc.) the elevator control device 16 transmits to the server 28 an elevator installation data set 30 which describes the elevator installation 10, in a data telegram (termed telegram for short in the following). The elevator installation data set 30 is stored on the side of the server 28 in a database (not shown separately) provided for that purpose and can be called up at the server 28 from this database.

(15) The illustration in FIG. 3 shows one possible layout of the elevator installation data set 30 and individual items of data included in the elevator installation data set 30 in correspondence with the approach proposed here. Belonging to these data is an elevator installation identifier 32, which uniquely identifies the respective elevator installation 10 and which is indicated in FIG. 3 symbolically and by way of example as 200971. The data additionally included in the elevator installation data set 30 describe the elevator installation 10 by further details. To that extent, belonging to the data are a statement about the numbers of the floors 18 (floor number 34), a statement about the numbers of the elevator cars 14 (elevator number 36) and a coded statement about the kind of control (control type 38). The control type 38 encodes whether the respective functionality of the elevator control device 16 is a conventional control, a group control, a destination call control or a control with special functions. Special functions can be functions with access control possibilities as well as additionally or alternatively execution of a travel request appropriate to a handicapped person or an implementation which facilitates boarding by mothers or users with child carriages, shopping trolleys, etc., and which provides for that purpose a longer opening time of the car and floor doors.

(16) The elevator control device 16 in every instance transmits an elevator installation data set 30 with an elevator installation identifier 32 to the server 28. The respective elevator installation 10 is then known on the side of the server 28 and use of the elevator installation 10 is possible within the scope of the concept proposed here. The elevator control device 16 can transmit the above-mentioned further elevator-installation-specific data 34, 36, 38 together with the elevator installation identifier 32 in the elevator installation data set 30. Alternatively, there is also the possibility of the elevator control device 16 transmitting these elevator-installation-specific data 34, 36, 38 to the server 28 only when a request is made by the server 28 at the elevator control device 16.

(17) The interaction with the elevator installation 10, namely the elevator control device 16, by means of the mobile radio 24 in correspondence with the approach proposed here is described in the following:

(18) Transmitter units 40 (FIG. 2) at each floor 18, or at least at those floors 18 at which the approach described here is to be usable, belong to the elevator installation 10. At least one transmitter unit 40 is present on each floor 18 of that kind.

(19) The transmitter units 40 are not necessarily connected with the elevator control device 16. However, in all cases the transmitter units 40 are spatially associated with the elevator installation 10 and, for example, mounted in the vicinity of the floor doors (at the walls or at the floor ceiling). The transmitter units 40 permanently transmit, thus regularly at predetermined or predeterminable intervals, for example every second, a floor-specific identification code 42 in the form of a so-called broadcast. Because the identification code 42 is transmitted as a broadcast, every mobile radio 24 present in the transmission range of a transmitter unit 40 can receive the identification code 42. The range of the transmitter units 40 is in the region of 4 to 10 meters depending on the respective requirements. In the case of other building topologies, thus particularly in the case of especially large buildings, a greater range can also be provided as long as it is guaranteed that an identification code 42 transmitted by a transmitter unit 40 of a first floor 18 can be received only on this floor 18 and not also on another floor 18. The transmitter units 40 transmit the identification code 42 by means of WLAN, WiFi, WPNA, by way of Bluetooth or ZigBee or according to methods which are known or become known in the future for data transmission between apparatus over a short distance by radio. In principle, data transmission according to the NFC standard is also conceivable.

(20) If the transmitter units 40 are in communicating connection with the elevator control device 16 by line coupling or line-free coupling there is the possibility of using a variable identification code 42 predetermined or at least influenced by the elevator control device 16. In this way, a user can obtain on his or her mobile radio 24 in the context of receipt of an identification code 42 additional data about the elevator installation 10, for example information whether a specific elevator is out of operation. If the transmitter units 40 are independent of the elevator control device 16, these transmit a predetermined or predeterminable identification code 42 which, for example, is settable in each transmitter unit 40 either in the context of programming or, for example, by way of so-called DIP switches or the like.

(21) The illustration in FIG. 4 shows one possible layout of the floor-specific identification code 42 and individual items of data included in the identification code 42 in correspondence with the approach proposed here. Belonging to these data are an identification code prefix 44, an elevator installation identifier 46 uniquely identifying the respective elevator installation 10, a floor designator 48 and an optional transmission authentication code or message authentication code 50 provided for safeguarding the identification code 42 against falsification.

(22) The floor designator 48 comprises either the respective floor number or a coded form of the floor number. Due to the fact that the identification code 42 comprises the floor designator 48, the identification code 42 is floor-specific. In the case of the situation shown in FIG. 4, the identification code 42 is floor-specific and elevator-installation-specific because it includes, apart from the floor designator, also the elevator installation identifier 46.

(23) The respective value of the message authentication code 50 is determined by the transmitter unit 40 in correspondence with an algorithm implemented in the transmitter unit 40, for example as a coded hash message authentication code (HMAC).

(24) As soon as the user enters, by his or her mobile radio 24, the transmission range of a transmitter unit 40 the mobile radio receives an identification code 42 transmitted as a broadcast by the respective transmitter unit 40.

(25) The illustration in FIG. 5 shows for that purpose the mobile radio 24 with further details insofar as these are of significance for explanation of the approach proposed here. Accordingly, the mobile radio 24 comprises in a mode and manner known per se a transmitting and receiving unit 52, a memory 54 and a processing unit in the form of or of such a kind as a microprocessor 56. The transmitting and receiving unit 52 is here shownschematically simplifiedas a single functional unit. The transmitting and receiving unit 52 is arranged in any case for the purpose of transmitting and receiving data in accordance with the respective mobile radio standard as well as receiving data from the transmitter units 40 in accordance with the respective data transmission method used by these. To that extent an actual implementation of such a transmitting and receiving unit 52 can comprise a plurality of functional units, thus, for example, a functional unit for transmitting and receiving data in accordance with the respective mobile radio standard and one or more further functional units for transmitting and receiving Bluetooth data, ZigBee data, etc.

(26) An identification code 42 received by a transmitting unit 40 is evaluated by a software application 58 loaded in the memory 54 of the mobile radio 24 in a mode and manner known per se. The software application 58 is, in a mode and manner known per se, a computer program with program code instructions included therein. Under control of the software application 58, the mobile radio 24 transmits the received identification code 42 to the server 28 via the respective mobile radio network and the internet 26. The server 28, thus a server program running at the server, checks whether the thus-received identification code 42 is valid. For that purpose, at least the identification code prefix 44 and the message authentication code 50 are evaluated. The identification code prefix 44 respectively included in the identification code 42 can largely be selected as desired at the time of programming or configuration of the transmitting units 40 and shall at least ensure that the server 28 recognizes an identification code 42 entering thereat as relevant use data and these are distinguishable from other use data which in particular circumstances similarly enter the server 28.

(27) On receipt of a valid identification code 42 the server 28 transmits the associated elevator-specific data back to the respective mobile radio 24. For that purpose, the server compares the elevator installation identifier 46 included in the identification code 42 with the elevator installation identifier 32 of the elevator installation data sets 30 filed in its memory. As soon as a match is made, the data included in the respective elevator installation data set 30 or also the elevator installation data set 30 overall can be transferred as elevator-specific data to the mobile radio 24.

(28) The server 28 thus comprises means for retrievable storage of at least one elevator installation data set 30 received by an elevator control device 16, means for determining an elevator installation data set 30 matching a received identification code 42, and means for transmitting such a matching elevator installation data set 30 to a mobile radio 24. The means for retrievable storage of one or more elevator installation data sets 30 can be a memory in the form of a hardware memory and/or in the form of usual memory devices (hard discs and the like) as well as a software functionality for management of the memory content and for access to the memory content. The means for determining an elevator installation data set 30 matching a received identification code 42 can be a software functionality which runs at the server 28 and is intended and arranged for comparison of the elevator installation identifier 46which is included in the identification code 42with the elevator installation identifier 32 of the or each elevator installation data set 30 stored at the server 28. For transmission of such a matching elevator installation data set 30 to the respective mobile radio 24 the server 28 is connected with, for example, the internet 26 and by way of the internet 26 with the mobile radio network in which the mobile radio 24 is reachable.

(29) For simplification of the further description and the illustration in FIG. 2 it is assumed that the server 28 communicates to the mobile radio 24 on a valid identification code 42, which is obtained from a mobile radio 24, the respectively associated original elevator installation data set 30 obtained from the elevator control device 16. It can obviously also be provided here that only the still relevant data of the elevator installation data set 30, thus, for example, not the elevator installation identifier 32, are communicated to the mobile radio 24. Moreover, the data actually communicated to the mobile radio can also comprise additional data and accordingly extend beyond the data of the original elevator installation data set 30. All this is to be comprehended by the use of the term elevator installation data set 30, insofar as there is meant an elevator installation data set 30 communicated by the server 28 to the mobile radio 24, and accordingly is to be read into this at all times.

(30) The data communicated in the form of the elevator installation data set 30 from the server 28 to the mobile radio 24 can also be filtered at the server 28 on the basis of the floor designator 48 included in the identification code 42, for example if in the case of an elevator installation 10 with a plurality of elevator cars 14 individual elevator cars 14 are not usable at the floor 18 which is designated by the floor designator 48 and on which the user is currently present. Moreover, under control of the software application 58 and after receipt of the elevator installation data set 30 from the server 28 the floor 18 on which the user is present can be displayed on the display (image screen) of the mobile radio 24. Such a display is in principle possiblesimilarly under the control of the software application 58already after receipt of the identification code 42 from one of the transmitter units 40. If the display of the floor number on the display of the mobile radio 24 takes place only on receipt of the elevator installation data 30 from the server 28 the displaying of the floor number on the display of the mobile radio 24 is already a report to the user that a successful communication with the elevator installation 10 has taken place.

(31) The user now has the possibility by means of his or her mobile radio 24 and the software application 58 running thereon to undertake control actions with respect to the elevator installation 10. Such a control action is, for example, a travel request. If by means of the software application 58 the user inputs a travel request, for example from the floor with the number 5 (starting floor) to the floor with the number 2 (destination floor), a travel request transmission 60 automatically generated by the software application 58 on the basis of this travel request (FIG. 5, FIG. 6; first travel request transmission 60) is transmitted to the server 28.

(32) The illustration in FIG. 6 shows that the server 28 after receipt of such a travel request transmission 60 for its part transmits a corresponding travel request transmission 62 (second travel request transmission 62) to the elevator control device 16.

(33) To that extent, the server 28 comprises means for receiving and transmitting such travel request transmissions 60, 62. For that purpose, the server 28 is, for example, connected with the internet 26 in a mode and manner known per se, wherein the travel request transmission 60 originating from the mobile radio 24 is initially communicated by way of the respective mobile radio network to the internet 26 and passed by means of the internet 26 to the server 28 and wherein the travel request transmission 62 transmitted by the server 28 passes by way of the internet 26 to the elevator control device 16.

(34) The illustrations in FIG. 7 and FIG. 8 show in schematic, simplified form one possible layout of such travel request transmissions 60, 62. The travel request transmission 60 transmitted by the mobile radio 24 to the server 28 comprises at least a specification of the respective destination floor (destination floor specification 64). A specification of the respective destination floor is in principle sufficient here because the starting floor, thus the floor on which the user is present, is already known at the server 28 from the preceding communication of the identification code 42. The travel request transmission 62 transmitted by the server 28 to the elevator control device 16 comprises at least a specification of the respective starting floor (starting floor specification 66) as well as the respective destination floor specification 64.

(35) The elevator control device 16 executes in due course the journey specified in this way by means of the travel request transmission 62, i.e. the elevator control device 16 moves the elevator car 14 to the floor 18 on which the user is present and conveys the user, after boarding the elevator car 14, to the destination floor. When the elevator control device 16 can execute the travel request corresponding with the travel request transmission 62 it is preferably providedbut in principle optionalthat the elevator control device 16 automatically generates an acknowledgement transmission (not shown) and transmits it to the server 28. The server 28 returns such an acknowledgement transmission to that mobile radio 24 which has triggered the travel request on which the travel request transmission 62 is based. In this way, the user can be informed by way of the user interface of the software application 58 of his or her mobile radio 24 that his or her travel request can now be fulfilled. The data transmissible in this way to the mobile radio 24 can, however, also emanate from a simple readiness report and, for example, can comprise data about which elevator car 14 shall complete the travel request so that by means of the user interface of the software application 58 it is indicated to the user which elevator car 14 is to be used.

(36) It can be provided for the data transmissions exchanged between the mobile radio 24 and the server 28 on the one hand and the server 28 and the elevator control device 16 on the other hand, thus in particular the travel request transmissions 60, 62, that these each comprise an identifier in the manner of the elevator installation identifier 32, 46 and/or are secured in another mode and manner.

(37) In use of a method in accordance with the approach proposed here in railway stations, shopping centers, parking garages, apartment blocks and the like there is no communication, in the context of communication of the travel request transmissions 60, 62, of a user identifier identifying the respective user. This is nevertheless possible in special use situations and is embraced by the approach proposed here. It can then be additionally checked, for example, in an elevator installation 10 with access control whether the user is authorized for the requested journey. In a given case the travel request is then refused. There is then no communication of a travel request transmission 62 to the elevator control device 16. A report in the form of a data transmission, which appropriately informs the user, can optionally be automatically transmitted by the server 28 to the requesting mobile radio 24. Additionally or alternatively it can be provided that floors 18 which need special authorization are not even displayed by the software application 58 of the mobile radio 24 if a user identifier connected with a corresponding authorization for individual or all floors 18 is not transmitted by means of the travel request transmission 60 or in conjunction with the communication of the travel request transmission 60. Such a restricted display of specific floors 18 by the user interface represented by the software application 58 can be ensured by communication of appropriately restricted data from the server 28 to the software application 58 of the mobile radio 24, for example in that the server 28 communicates to the mobile radio 24 in a response transmission (not shown) on receipt of the travel request transmission 60 a list with the floors 18 accessible in correspondence with the communicated user identifier. Accessible and non-accessible floors 18 as well as optionally an authorization, which is necessary for a floor 18 not accessible without further measures, and the like can be filed at the server 28 in the database thereof and/or conjunctively notified to the server 28 by the elevator control device 16 with the elevator installation data set 30 or in connection with the communication of the elevator installation data set 30.

(38) The software application 58 can also graphically represent accessibility or non-accessibility to individual floors 18, for example in that only those floors 18 which can be travelled to by the user are displayed, for example, by the respective number thereof. Additionally or alternatively, by means of a user interface illustrated by the software application 58 it is possible for floor buttons or the like to appear in an active or an inactive form and/or be colored (for example green=accessible, red=blocked) and/or characterized by a readily understandable symbol (for example lock with closed yoke=blocked, lock with open yoke or illustration without such a symbol=accessible).

(39) The communicating connection between the server 28 and the elevator control device 16 is preferably designed, but in basically optional mode and manner, to be particularly secure. Coming into consideration here are coding and securing mechanisms known per se for securing the communication between the server 28 and the elevator control device 16, for example SSL, TSL, HTTPS, VPN and the like.

(40) The software application 58 makes possiblein a preferred, but basically optional, designuse of predetermined or predeterminable user profiles downloaded into the memory 54 of the mobile radio 24. A user profile can be directed to, for example, the requirement for an elevator car 14 appropriate to handicapped persons, to the requirement for a VIP elevator car 14, to longer opening times of the floor and car doors, to an optical and/or acoustic playing of special media and the like in the elevator car 14, etc. On the basis of such a user profile appropriate data are transmitted to the server 28, for example as a component of the travel request transmission 60, in connection with a travel request by the user by means of the software application 58. The server 28 checks the thus-obtained data and passes on these, for example as additional use data in the travel request transmission 62, to the elevator control device 16. Additionally or alternatively to such user profiles the software application 58 can offer, together with a specification of a travel request, thus at least the selection of a destination floor, further selection options by means of the user interface so that the user can more precisely formulate or additionally parameterize the respective travel request. It is thus possible, for example, for the user in order to fulfill his or her travel request to require a car appropriate to a handicapped person and/or for the user to book playing of a specific audio and/or video sequence for his or her travel request.

(41) The specification of a travel request can also be undertaken by the user before he or she is physically in the vicinity of the elevator installation 10. The user then undertakes specification of the respective destination floor, for example, when he or she is still present at his or her workplace and selects as destination floor, for example, the floor in which an underground garage is present. As soon as the user leaves his or her workplace and comes by his or her mobile radio 24 into the transmission range of a transmitting unit 40 the above-described data exchange with the server 28 and the elevator control device 16 takes place, in which case it is recognized on the part of the software application 58 running on the mobile radio 24 that a travel request is already present and the software application 58 accordingly automatically generates a travel request transmission 60 as soon as the identification code 42 has been received by a transmitter unit 40 and thus the data necessary for communication with a server 28 are present. In other words, the user can file a generic travel request in the mobile radio 24, which is communicated to the remote server 28 as soon as the mobile radio 24 comes into the receiving range of any, in particular undefined beforehand, transmitting unit 40. The starting floor can thus be dynamically determined by the identification code first received after activation of the generic travel request. Activation of the generic travel request can also take place on a time basis, for example every working day around 17.00 hours, and/or on a positional basis, for example by means of approach to the GPS position of the elevator location.

(42) Finally, the illustration in FIG. 9 shows from left to right snapshots of the user interface, which is represented by the software application 58 on the display of the mobile radio 24, in the case of use of the mobile radio 24 in the context of the approach described here.

(43) The illustration at the top left (display 24a) is one possibility for a representation such as is carried out when the mobile radio 24 is outside the transmission range of at least one transmitting unit 40. The software application 58 then seeks, so to speak, a building in which there is an elevator installation 10 to which access is possible in the above-described mode and manner by means of the software application 58.

(44) In the case of the illustration at the top right (display 24b) the software application 58 has received an identification code 42 from a transmitting unit 40 and in a given case has also already communicated this to the remote server 28 as well as received therefrom the elevator installation data set 30. A plain-text display of a designation of a respective building, here LucerneMain Station, can in principle take place already by virtue of the receipt of the identification code 42 by a transmitting unit 40. Equally, a representation of the respective floor 18 on which the user together with his or her mobile radio 24 is present, here EG for ground floor, can already take place by virtue of the receipt of the identification code 42.

(45) Preferably, but in principle optionally, it is provided that such displays take place only when the software application 58 has obtained the elevator installation data set 30 from the server 28. It is then guaranteed that the server 28 has checked the communicated identification code 42 and that the identification code 42 is a permissible identification code 42.

(46) The illustration at the bottom left (display 24c) is one possibility for design of the user interface for selection of the destination floor by the user. The software application 58 generates the travel request transmission 60 on the basis of such a selection.

(47) Finally, the illustration at the bottom right (display 24d) shows one possibility for design of the user interface for displaying that the travel request registered by the user can now be fulfilled and in the illustrated example also comprises information with respect to the elevator car 14 to be used, here an elevator car 14 denoted by the letter B.

(48) Although the invention has been more specifically illustrated and described in detail by the embodiment, the invention is not limited by the disclosed example or examples and other variations can be derived by the expert without departing from the scope of protection of the invention.

(49) Individual aspects, which are to the forefront, of the description filed here can thus be summarized briefly as follows: A method of operating an elevator installation 10, an elevator control device 16 and mobile radio 24 for carrying out the method as well as a system with such an elevator control device 16 and mobile radio 24 are indicated, wherein the control actions with respect to the elevator installation 10 can be undertaken by means of the mobile radio 24 and wherein the mobile radio 24 obtains relevant data, which enable immediate access to the elevator installation 10, initially in the form of an identification code 42 transmitted continuously or regularly by a transmitter unit 40 associated with the elevator installation 10.

(50) In accordance with the provisions of the patent statutes, the present invention has been described in what is considered to represent its preferred embodiment. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope.
