Abstract

Described are a system and method for monitoring pre-prepared meals which can be assembled as a plurality of portions. Assembled pre-prepared meals can be monitored starting from their assembly up to the ultimate consumption. Pre-prepared meals are arranged on tray-like containers and a data carrier is fastened which contains meal-specific data. These meal-specific data can be read out at at least two reading stations to be able to keep a record of the conditions of manufacture, storage and/or cooling.

Claims

1. A method for monitoring assembled pre-prepared meals which are arranged on a shelf such that the shelf supports both a meal to be heated and a meal or beverage not to be heated on said shelf, said method comprising the steps of:

(a) automatically storing meal-specific data on a data carrier which is coupled to the shelf;

(b) automatically reading out said data from said data carrier at at least one reading station; and

(c) heating the meal to be heated by controlling a device for heating the meal to be heated using said data stored on said data carrier and read out in a contactless manner, wherein said data carrier is configured for storage of data and for reading out of data at the at least one reading station, as well as the writing of data to the data carrier when the shelf is in a transport mode, said data comprising data on heating conditions and the respective position of the meal to be heated and of the meal or beverage not to be heated that are supported on the shelf, said heating device being controlled such that said heating device carries out heating only locally in a selective manner at a location of said shelf at which the meal to be heated is located and does not carry out heating at a location of said shelf at which the meal not to be heated or the beverage not to be heated is located, said meal specific data including data indicative of expiry of a maximum shelf life, said device further being controlled based on said meal specific data such that no heating of a meal can take place in said device after the expiry of the shelf life of the meal, and

wherein said method for monitoring further includes;

(i) automatically recording data at the reading station or at a central data processing unit on when the meal has been heated, such to update information by the reading station or at the central data processing unit as to which meals have already been heated, and

(ii) preventing any reheating of a previously heated meal, with updated status, while supported on the shelf.

2. A method in accordance with claim 1, wherein the step of automatically recording data comprises including an “

already heated”

record on the data carrier which is coupled to the shelf.

3. A method in accordance with claim 1, wherein said meal-specific data is stored in a wireless and contactless manner.

4. A method in accordance with claim 2, further comprising the steps of measuring temperature signals during said transportation and storage and storing said temperature signals as data on said data carrier.

5. A method in accordance with claim 1, further comprising the step of generating a warning signal in response to a recognition of an expiry of a maximum shelf life of a meal or beverage supported on the shelf.

6. A method in accordance with claim 1, wherein a wireless data transmission is carried out during the transportation in mobile means of transportation to a central reception system.

7. A method in accordance with claim 1, further comprising the step of transmitting said meal-specific data to and/or from said data carrier, said transmitting being carried out inductively or capacitively.

8. A method in accordance with claim 1, wherein said meal-specific data stored on said data carrier is made visually detectable from the outside on electronic display elements located on a meal trolley in which meals or a meal and a beverage arranged on the shelf are contained.

9. A method in accordance with claim 8, wherein said meal-specific data are displayed on said electronic display elements in plain text form.

10. A method in accordance with claim 8, wherein said meal-specific data are also displayed on display elements after deactivation of electrical energy.

11. A method in accordance with claim 1, wherein a multiplex data transmission and storage is realized at reading and/or transmitting units having a plurality of antennas for data.

12. A method for monitoring a pre-prepared meal assembly arranged on a shelf such that the shelf supports both a meal to be heated and a meal or a beverage not to be heated on said shelf, said method including:

(a) automatically storing meal-specific data on a data carrier which is coupled to the shelf;

(b) automatically reading out said data from said data carrier at at least one reading station; and

(c) heating the meal to be heated by controlling a device for heating the meal to be heated using said data stored on said data carrier and read out in a contactless manner, said data comprising data relating to heating conditions and the respective positions of the meal to be heated and of the meal or beverage not to be heated on the shelf, said heating device being controlled such that said heating device carries out heating only locally in a selective manner at a location of said shelf at which the meal to be heated is located and does not carry out heating at a location of said shelf at which is located the meal or the beverage not to be heated; and

(d) wherein said method further includes heating a plurality of said shelves each supporting a meal to be heated and a meal or beverage not to be heated, and said plurality of said shelves being positioned in a stack within a meal trolley positioned on a mobile means of transportation on which consumers of the pre-prepared meals are located; and

wherein, following heating;

(i) the data carrier of a respective, heated shelf is automatically adjusted to reflect an “

already heated”

state relative to a heated meal in the stack of container shelves in the meal trolley during transport on the mobile means of transportation;

or

(ii) a step of identifying with identification information the meal that went from a to-be-heated to a “

already heated”

state in the stack is carried out during transportation on the mobile means of transportation, and

(e) wherein the method further comprising preventing any heating of the already heated meal, while the already heated meal is supported on the shelf, based on an identification that the meal has achieved the “

already heated”

state.

13. The method of claim 12 wherein said meal trolley includes a display designation as to when there exists an “

already heated”

state for a specific heated meal in the shelf that has been heated with the heating device.

14. The method of claim 13 wherein the mobile means of transportation is one of an aircraft or rail vehicle, and heating is carried out during a first leg of travel and a writing of the “

already heated”

state to the data carrier avoids a re-heating on a subsequent, second leg of travel.

15. The method of claim 12 wherein the mobile means of transportation is one of an aircraft or rail vehicle, and heating is carried out during a first leg of travel and a writing of the “

already heated”

state to the data carrier avoids a re-heating on a subsequent, second leg of travel.

16. The method of claim 12 wherein there are plurality of meal trolleys on said mobile means of transportation, and wherein there is provided on said mobile means of transportation a galley, with said galley having a receiving and transmitting element as well as an intermediate data storage unit which stores data read relative to the shelves in said stacks of shelves stored in the meal trolleys.

17. The method of claim 16 wherein said intermediate data storage unit is positioned on said mobile means of transportation and is in wireless communication with a central data storage unit positioned at a location removed from said intermediate data storage unit.

18. The method of claim 16 wherein a storage device of a storage container of said galley also stores identification data for the respective meal trolleys.

19. The method of claim 12 wherein said meal trolley comprises two sides and said data carriers coupled to the shelves are configured to monitor for removal of a shelf through either of the two sides.

20. The method of claim 12 wherein said shelf includes a separate meal or beverage container supported on said shelf adjacent to a supported meal or beverage container also being supported by the shelf.

21. The method of claim 12 wherein the shelf is an aircraft food supply shelf.

22. The method of claim 12 comprising utilization of method step d(i).

23. The method of claim 12 comprising utilization of method step d(ii).
