The present invention relates to a system for stock management for on-board catering for a vehicle.
Although the present invention can be used in a variety of applications, it is explained in more detail, along with the problems on which it is based, with respect to passenger aircraft. However, the described methods and devices can also be used in different vehicles and in all fields of the transportation industry, for example for road vehicles, for rail vehicles, for aircraft or for watercraft.
Galleys which are currently provided on board modern passenger aircraft usually comprise storage locations or slide-in unit compartments into which containers and/or roller containers (referred to in English as “trolley” or “galley cart”) can be inserted, said containers being loaded with supplies or service products such as e.g. food and/or drinks to be supplied to the passengers on board the aircraft. In order to indicate the contents of the trolleys or containers they are classically provided with labels which the catering company applies during the loading process. In addition, lists are produced from which the cabin crew obtain a breakdown of the available service products and their storage positions in the aircraft galley. Since these lists for the cabin crew only convey the initial loading state of the aircraft galley, it is difficult for the cabin crew to maintain an overview of the stock of the galley during the flight.
Document DE 10 2009 058 327 A1 discloses a system for stockkeeping in an aircraft galley, in which system receptacle devices such as standard units, slide-in units or trolleys or the like are provided with transponders which emit identification signals which are characteristic of the content thereof and are in turn read in by a transceiver unit of the galley in order in this way to determine the stock of the galley. As a result, the overview over the stock of the galley is to be improved.
Against this background, an aspect of the present invention relates to finding improved solutions for the stock management for on-board catering, in which at any time the overview over the stock is maintained while the products are being distributed.
Accordingly, a system for stock management for on-board catering for a vehicle is provided. The system comprises a galley which is provided with a control unit for controlling the galley, wherein the control unit is designed to make available stock management data of the galley; a service unit for transporting supplies within the vehicle, wherein the stock management data comprise a stock record of the supplies transported with the service unit; and at least one operator control element which is communicatively connected to the control unit of the galley via a wireless data connection and is designed to record removal of a supply item from the service unit and/or reception of a supply item by the service unit, and to bring about updating of the stock record of the transported supplies on the basis thereof.
Furthermore, an aircraft having the system according to an embodiment of the invention is provided.
A concept on which the present invention is based is to administer a stock record of the existing supplies or service products centrally in the galley and to keep said record up-to-date even if in the meantime individual supplies have been distributed to the passengers or the crew or issued in some other manner. For this purpose, aspects of the present invention makes available a wireless data connection which connects the galley to at least one operator control element. The operator control element or elements serves/serve to detect the issuing of a supply item from the service unit and to communicate this information to the galley via the wireless connection. On the basis thereof, the stock record is then correspondingly updated. The reception of a supply item by the service unit can also be correspondingly recorded and the stock record correspondingly updated. Therefore, the currently present stock of supplies can be called up in the galley at any time. Ultimately, an aspect of the invention provides the possibility of tracking present service products and monitoring their availability in an automated fashion, in particular in real time, in a cabin of a vehicle. For example, the at least one operator control element can communicate a current position, i.e. in which row of passengers and/or in which cabin section the controlling person, i.e. the operator control element, and/or the service unit are located. An aspect of the invention therefore makes available an automated merchandise management system for catering goods for a vehicle, in particular for a vehicle cabin, which system informs the cabin crew at any time in a dynamic fashion about the current stock of the goods and their order situation.
For example, personnel of a vehicle cabin can carry such an operator control element on their person, e.g. in the form of a portable computer, a mobile terminal or a smart mobile device. In another example, the operator control element can be arranged or mounted on a roller container which serves as a service unit and/or can be integrated therein in some other way. As soon as the cabin crew, e.g. flight attendants, remove a product from the roller container or some other service unit and issue it to a passenger, the removal of the product can be detected using the operator control element and the product can, if appropriate, be identified automatically, e.g. using a barcode scanner or the like. Subsequently, updating of the stock list or the stock record can be brought about by means of the operator control element, which list or record is assigned to this roller container or this service unit and comprises a listing of the products which are contained or transported therein.
A service unit according to an embodiment of the invention denotes, on the one hand, service vehicles, i.e. trolleys, food trolleys or the like. However, service units according to an embodiment of the invention also comprise general receptacle devices or transportation devices for supplies and/or service products such as, for example, containers, standard units or the like. Furthermore, a tray or a corresponding transportation device can also constitute a service unit according to an embodiment of the invention. In this case it is registered whether a supply item is removed from the tray or placed on said tray. Subsequently, the stock record of the tray is correspondingly updated. It will become clear here to a person skilled in the art that an aspect of the present invention basically permits the wireless connection of the galley with a multiplicity of such service units. A multiplicity of operator control units can also be provided.
The wireless connection according to an embodiment of the invention can be implemented, for example, by means of a wireless local network, e.g. a WLAN or the like. Different embodiments are conceivable for this purpose. For example, a wireless network which is already present in any case for other purposes in a passenger cabin can be used. On the other hand, it is conceivable to make available a separate wireless network specifically for this purpose. This may be, in particular, a secured network which can only be accessed by persons or devices with corresponding security authentication, e.g. the on-board personnel of the vehicle and/or corresponding electronic devices which are to be/can be operated only by the on-board personnel.
Advantageous refinements and developments emerge from the description with reference to the figures.
According to one development, the at least one operator control element can have an identification unit. The identification unit can be designed to identify a supply item on the basis of a label which is attached thereto. For example, optoelectronically readable text such as barcodes or the like can be attached to the outside of the supplies and can be recognized by the identification unit. The identification unit can correspondingly be embodied, for example, as a barcode scanner or the like. Barcodes according to an embodiment of the invention comprise here both unidimensional and linear barcodes, i.e. in particular barcodes as well as two-dimensional designs or matrix codes, e.g. QR codes, etc. Alternatively or additionally, the identification unit can be designed for general object recognition. For example, the identification unit can have a camera which can be used to capture shapes, colours, etc. of objects and/or surfaces and identify a supply item on the basis thereof.
According to one development the identification unit can be embodied as a barcode reader. The identification unit can therefore be embodied as a data acquisition device which can read and pass on various barcodes or the like. The barcode reader can be configured, for example, as a CCD scanner, laser scanner or the like. However, barcode readers according to an embodiment of the invention also comprise camera scanners or imagers, i.e. devices which capture a barcode using an, in particular optical, camera, and subsequently prepare the captured image by means of digital image processing, in order to capture the barcode in digital form.
According to one development, the at least one operator control element can be designed to display the stock management data. For example, the operator control element can have a display such as a screen or some other electronic optical display on which the stock management data can be displayed. In a specific example, the operator control element can be a smart mobile device, e.g. data glasses (smartglasses) which can project information onto one or both lenses of the glasses. The data glasses can also be equipped with a camera scanner which is designed to capture barcodes. Furthermore, the data glasses can be connected to a (secure) wireless network. The flight personnel can wear such data glasses, for example while serving food and/or drinks. The data glasses can capture and identify each service product which is served, so that the stock record of the service products can be kept up-to-date at all times by the transmission of data via the wireless network, without the usual catering operation being in any way impeded or adversely affected.
According to one development, stock management data can comprise catering data, passenger data and/or cabin data or the like. The stock management data therefore comprise in this development not only a stock record or a stock list of one or more service units or of the galley. Furthermore, various additional information items or data can be included. For example, the stock management data can contain catering data which is made available by a catering service provider and can contain, inter alia, information about the supplied on-board catering, i.e. which products are made available to what extent and in which form. Furthermore, the stock management data can contain passenger data which include e.g. data about which passengers have registered specific catering requests or options. Furthermore, the stock management data can contain cabin data. Cabin data can comprise, for example, a seating plan of the passengers.
According to one development, the at least one operator control element can comprise a first operator control element. The first operator control element can be embodied as a portable computer.
According to one development, the first operator control element can be a tablet computer, a smartphone, a smartwatch or data glasses (smartglasses).
According to one development, the at least one operator control element can comprise a second operator control element. The second operator control element can be integrated by the service unit. For example, the second operator control element can be attached to or (releasably or non-releasably) mounted on the outside of the service unit, for example in the form of a touchpad or a tablet computer. In another example, the second operator control element can be a touchscreen or electronic operator control pad which is embedded in a housing of the service unit. The second operator control element can also have an identification unit, e.g. a barcode reader by means of which supply products can be registered. For example, the operator control element can be integrated into a service trolley or roller container. Alternatively or additionally, the operator control element can, for example, also be integrated into a tray, which can therefore detect the placing of supplies thereon or removal of said supplies therefrom as a “smart tablet”.
According to one development, the second operator control element can be a touchscreen and/or an electronic operator control pad.
According to one development, the at least one operator control element can be designed to identify the service unit and to assign the stock record to the service unit on the basis thereof. In one embodiment, for example customary roller containers can be used without an electronic connection to the wireless network. The roller containers can be labelled, for example, with a barcode or some other labelling means. By means of the label it is possible in turn to assign a stock record unambiguously to the roller container in the existing stock management data, wherein the information can be made available, for example, as catering data by a catering service provider. The operator control element can have, for example, an identification unit, e.g. a barcode reader, which is used to identify the roller container. On the basis thereof, the assigned stock record can be updated centrally by means of the operator control element during subsequent service of food and/or drinks without the roller container itself having to be connected to the wireless network in any form. Alternatively or additionally, in addition to barcodes it is also possible to use other identification means. For example, the service unit can have an RFID tag or the like, which can be read out from a reading device or identification device provided in the operator control element.
According to one development, the at least one operator control element can be designed to authenticate itself with respect to the service unit, wherein access to the stock record of the service unit and/or the supplies of the service unit is enabled after successful authentication. In particular, the operator control element can be designed to administer the access to the supplies and/or the stock record of the service unit, i.e. enable or disable this access. In this development, it is possible, inter alia, to implement a digital lock system in which the on-board personnel must firstly authenticate themselves using the operator control element before said personnel receive access to the content and/or data of the service unit. The operator control element, e.g. a smartphone or a tablet computer, can comprise a software application which can be used to lock and unlock the service unit, in order to disable or enable the access to the transportation items and/or the data of the service unit. The locking means can be, for example, an electronic locking means which can be activated via a wireless data connection. For example, the service unit can be identified by means of a RFID tag attached thereto. Certified operator control elements can then authenticate themselves by means of corresponding software applications, and after successful authentication they can access the data and/or the supplies of the service unit. It will become clear to a person skilled in the art here that a lock system can also be implemented purely at the level of software, i.e. therefore only the access to the data of the service unit can consequently be administered. Likewise, combinations of hardware solutions and software solutions are possible.
According to one development, the service unit can comprise a data memory. The data memory can be designed to store the stock record. In principle, in this context different designs are conceivable. For example, the service unit can contain a data memory which can be written to once or re-written to and which can be written to exclusively by a catering service provider and can only be read by the flight personnel, e.g. by means of the at least one operator control element. In this case, the stock record can be updated centrally by means of the control unit of the galley for each service unit. However, it is also alternatively or additionally possible to provide that an active intervention in the data memory is enabled for the flight personnel, with the result that an updated version of the stock record can be produced directly on the data memory of the service unit.
According to one development, the at least one operator control element can be communicatively connected to the data memory of the service unit and be designed to read the stock record out of the data memory. For example, the service unit can be equipped with an active or passive RFID tag which comprises a corresponding transponder and an electronic data memory which can in turn be read by a suitable reading device which can be integrated into the at least one operator control element. For example, the stock record can already have been created by a catering service provider on the data memory in accordance with the supplied equipment of the service unit before the loading onto the vehicle occurs. The flight personnel can then identify the service unit and/or detect its contents using the operator control element before use occurs. The corresponding stock record is continuously updated during use in the customary way by using the operator control element to register each product which is given out.
According to one development, the at least one operator control element can be communicatively connected to the data memory of the service unit and be designed to bring about updating of the stock record on the data memory when a supply item is removed from the service unit and/or a supply item is input by the service unit. In this development, the service unit (or generally each service unit of a multiplicity of service units) therefore has a current version of its stock record. This can be read out and updated at any time by the flight personnel by means of an operator control element. At the same time, a central version of the stock record of this service unit can also be continuously updated.
According to one development, the service unit can comprise a service unit display. The service unit display can be designed to display the stock record. In one example, the service unit display can be made available in the form of an electronic optical display with an operator control function, e.g. as a touchscreen, via which additional inputs can be made and which serves at the same time as an operator control element of the system. In another example, the service unit can merely have a service unit display without further operator control functions, which service unit display is designed exclusively to output the stock record or other stock management data. In another example, the service unit can have a service unit display for displaying the stock record and additionally a separate operator control element which is coupled to the galley via the wireless connection.
According to one development, the galley can have a galley display. The galley display can be designed to display the stock management data. The galley display can be embodied in specific examples as an electronic optical display or display with or without operator control functions, e.g. as an LED, OLED, TFT or LCD screen or the like with or without background lighting and/or as a touchscreen, etc., which in addition to the outputting of information, also permits inputting via a screen which serves as a touchpad. The galley display can serve to monitor and/or control the galley. For this purpose, the galley display can be coupled to the control unit.
According to one development, the control unit of the galley can be communicatively connected to a cabin management system of the vehicle. For example, the control unit can be connected to a controller area network (CAN) of a cabin management system or the like, via which a connection to external catering service providers, airlines, etc. can also be possible.
The above refinements and developments can be combined with one another as desired where appropriate. Further possible refinements, developments and implementations of the invention also comprise non-explicitly specified combinations of features of the invention which are described above or below with respect to the exemplary embodiments. In particular, in this context a person skilled in the art can also add individual aspects as improvements or additions to the respective basic form of the present invention.
The present invention will be explained in more detail below on the basis of the exemplary embodiments specified in the schematic figures, of which:
The appended figures are intended to convey better understanding of the embodiments of the invention. They illustrate embodiments and serve to explain principles and concepts of the invention in conjunction with the description. Other embodiments and many of the specified advantages are apparent from the drawings. The elements of the drawings are not necessarily shown true to scale with respect to one another.
In the figures of the drawing, identical, functionally identical and identically acting elements, features and components are, unless stated otherwise, each provided with the same reference symbols.
The system 1 is provided in a vehicle cabin 14 of an aircraft 100, in particular of a passenger aircraft, as is illustrated by way of example in
The upper galley monument 18 comprises an integrated galley display 12. The galley display 12 can be, for example, a screen with OLED or LCD technology or the like, wherein the galley display 12 can be embodied in a touch-sensitive fashion as a touchscreen or touch display. In addition, the galley display 12 can be movably coupled to the galley monument 18. The galley display 12 serves in this exemplary embodiment as a monitoring and/or operator control device for the galley 2. For this purpose, the galley display 12 is connected to a control unit 3 which is designed to control the galley 2. The control unit 3 is in turn connected to a cabin management system 13, e.g. with a controller area network (CAN) or the like. The control unit 3 here can contain further components which are not illustrated, such as for example a microprocessor, a data memory, databases, etc.
The control unit 3 is also designed to make available stock management data of the galley 2, which data can be displayed via the galley display 12. The stock management data comprise, on the one hand, a stock record for each of the service units 4, i.e. for example for the roller container which is located on the left in
The system 1 additionally comprises a first operator control element 10 which is communicatively connected to the control unit 3 of the galley 2 via a wireless data connection 7, e.g. a secured WLAN network. In the exemplary embodiment in
The first operator control element 10 is also embodied as data glasses which display stock management data, e.g. on one of the lenses of the glasses (indicated by a dashed line on the first operator control element 10 in
In the illustrated embodiment of the system 1 there are multiple possible ways of also integrating the service units 4 into the system. In a simple embodiment, the service units 4 can merely be integrated passively into the system 1 without being able to communicate actively via the wireless network 7. Instead, the service units 4 can merely have identification labels, e.g. a barcode. In the exemplary embodiment in
The first operator control element 10 can also be designed to authenticate itself with respect to the service unit 4, wherein access to the stock record of the service unit 4 and/or the supplies 5 of the service unit 4 is enabled after successful authentication. The authentication can be carried out, for example, via the wireless network 7, e.g. by means of a corresponding software application which is stored on the first operator control element 10. It is possible to implement on this basis a lock system for the service unit 4 which can be used to unlock and lock the service unit 4 by means of the first operator control unit 10.
Alternatively or additionally, the service unit 4 can also comprise a data memory 6 on which, inter alia, the stock record can be stored. The first operator control element 10 can then be connected to the data memory 6, e.g. the data memory can be coupled to the RFID tag 17 and/or connected to the wireless network 7. In this way, the stock record can not only be stored locally on the service unit 4 (and for example already stored with the delivery of the service unit 4 by a catering service provider) but, moreover, updated at any time by means of the first operator control element 10. The service unit 4 can additionally comprise, for example, a service unit display 11 on which information about the stock record of the service unit 4 and/or about products can be displayed. In this way, the service unit display 11 can function, as it were, as an electronic label.
The system 1 can basically comprise, in addition to the first operator control element 10, further operator control elements which can be embodied differently. For example, in addition to data glasses it is also possible to use smartphones, smartwatches, tablet computers and/or other portable computers. In the embodiment in
Basically, the system 1 in
In this specific example, the service unit 4 carries a multiplicity of supplies 5 in the form of trays which are each pre-packed with a plurality of products, e.g. ready-made meals, drinks, etc. Each tray 5 is provided here with a label 9, e.g. a barcode (cf. the tray 5 top left in
Likewise there may be provision that the products which are located on the tray 5 are identified directly, e.g. likewise by means of barcodes or the like which are attached to the products. In alternative refinements, the identification unit 8 can also determine the external shape of the products and on this basis identify the products and/or the trays 5, e.g. by optically capturing the external shape, for example on the basis of object recognition algorithms, which are based on object models of the products. The identification unit 8 can be fixedly integrated into the service unit 4. Alternatively, the identification unit 8 can be part of a portable operator control element and/or can be coupled communicatively thereto.
In this case, the service unit 4 is embodied as an electronic tray which, by means of an operator control element 10′, detects the supplies 5 which have been placed on the tray and/or removed therefrom, and identifies said supplies by means of labels 9 which are attached to the supplies 5. For this purpose, the operator control element 10′ comprises an identification unit 8 which can be embodied, for example, as a barcode reader. In addition, the operator control element 10′ optionally has a service unit display 11 which can, for example, output information about the stock record. The tray is therefore embodied as a “smart tablet”, wherein the stock record is automatically updated.
In the exemplary embodiment in
The essential advantages of the described stock management for on-board catering can be summarized as follows:
