BACKGROUNDCommercial aviation tends to be a very competitive industry vying for the consumer's dollar. To compete in the industry, airlines must strive to be efficient in all areas while offering passengers amenities that bring attention to the airlines and induce passengers to fly with a particular airlines. One area of interest to the passengers is the inflight experience, including the food and beverage service. Passengers want a variety of options for food and beverage, which is a challenge to the airlines who want to conserve weight and space. The conflict between passenger experience and airline economics is never more prominent than in in the aircraft's galley. An aircraft galley refers to the area of the vehicle that is used by the flight attendants to service the passengers, particularly the passengers' food and beverage needs. Due to constraints with space and weight, these areas are very ordered and efficient in all aspects of their construction and arrangement. One important consideration in the design of the galley is the power distribution and power consumption of the various equipment, or “inserts.” Inserts can be any power consumer such as a coffee brewer, an oven, a trash compactor, an overhead light, or any other electrical appliance that can be found in the galley area. Power on an aircraft is a limited and controlled commodity, and the control of the power is an important consideration in every galley.
The power arrangement of the aircraft galley is traditionally been a series of individual appliances connected to a main power supply, each appliance individually operated by its own controls, power switch, etc. Because power is limited on a flying aircraft, the management of this power is critical to the safe and reliable operation of the aircraft. However, with each individual appliance operating independently of the other appliances, control over the power structure is limited. Also, there is no easy way of discerning an overall health of the power system or run diagnostics of the system. Rather, each applicant must be polled individually to determine its health, operational condition, maintenance, etc. Because of the arrangement of some galleys, this can be labor intensive and expensive to conduct. What the art needs is a galley power system than can interface with all of the various equipment in the galley, run diagnostics and service inquiries, and control the galley through an interface that manages the power according to a hierarchy.
Another aspect of the efficiency of the galley is the communication between galleys, flight attendants, and passengers. The service and satisfaction of the passengers is of great concern to airlines, but there are challenges to attending to so many customers confined in such close quarters. Most communication is either vocal, or in some cases there is limited electronic communication between the passengers and the galley. However, the state of the art aircraft lacks a comprehensive communication system that links the passengers, galley, and flight attendants in an efficient manner.
SUMMARY OF THE INVENTIONThe present invention is an integrated galley and appliance operating system for use in an aircraft that consolidates the operation and power distribution of the galley to a single control panel. The integrated galley and appliance operating system provides a single operating interface for electrical appliances such ovens, coffee makers, toasters, refrigerators, lighting, etc., eliminating the need to control each appliance at its individual controls. A total system controller (TSC) is located remote from the individual appliances with sufficient capability to operate each one individual appliance or as combined functions. For example, using the system controller, two or more ovens could be started on similar cooking cycles starting at the same time. The result is that the meals are finished at the same time, reducing work load on the attendants. In addition, the controller monitors all of the appliances and prioritizes the power requirements. The total system controller also preferably monitors appliances for diagnostic purposes, and produces a system “health” status to aircraft maintenance personnel or maintenance communication systems. The integrated control system has the power controls built in and provides power management for optimizing power usage.
The galley control of the present invention includes an integrated communication system that links passengers, flight attendants, and galleys, through voice or electronic messaging. This allows passengers to communicate with the galley, and galleys to communicate with each other, in order to better service the passengers. Moreover, using handheld devices such as smart phones, PDAs, or other communication devices, the galley can also communicate with flight attendants throughout the aircraft. The communication system improves efficiency and allows for more expedient and better service to the passengers.
Other features and advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments in conjunction with the accompanying drawings, which illustrate by way of example the operation of the invention.
In operation, each GAIN requests power from the power control and distribution device 110, which allocates the available power from the main galley power unit 100 to the requesting GAIN based on a hierarchy in its control logic. Each of the various GAINs is assigned a priority, and the power control and distribution device maintains the priority in allocating the limited power available to the galley.
The integrated galley and appliance operating system of the present invention provides a single operating interface (control panel 30) for electrical appliances such ovens, coffee makers, refrigerators, etc., eliminating the need for individual controls at each appliance. A total system controller unit 40 is located remote from the appliances with sufficient capability to operate each one individually or as combined functions. For example, two or more ovens could be started on similar cooking cycles through the controller unit 40 starting at the same time. The result is that the meals are finished at the same time, reducing work load on flight attendants. In addition, the controller 40 monitors all of the appliances and prioritize work efforts. The total system controller 40 also preferably monitors appliances for diagnostic purposes, and produces a system “health” status to aircraft maintenance personnel or maintenance communication systems. The integrated control system has the power controls built in and provides power management for optimizing power usage. Thus, the integrated controller approach is a new concept that reduces overall parts and components in the galley, saving weight, costs, space, and time in the operation of the galley.
The capacity to start or operate multiple aircraft galley GAINs using a single, remote control panel is a useful feature of the present invention. For example, setting a temperature for all of the galley chillers at one time, or setting all of the oven temperatures from the control panel is not found in current systems. Moreover, the integrated approach allows for power allocation from a power control and distribution unit, which distributes power to the various equipment in the galley according to a predetermined protocol. This ensures that the power requirements of the galley are met and that certain lower priority GAINs do not usurp power from higher priority power clients. Moreover, the integrated galley includes a display panel that monitors the status functionality of the galley inserts. Monitoring the equipment is accomplished by scrolling or requesting the information from the control panel, which can access the status of each equipment and provide rapid response to the request for status of each individual apparatus.
Another preferred feature of the control panel 30 is a communication system that is established between galleys on the aircraft, passengers and the galley, and flight attendants interacting with both the galley and the passengers.
In addition to the passenger link 306, there is a galley-to-galley link 312. Display element 310 illustrates a list of other galleys on the aircraft (M1, M2, . . . M5). To establish a communication link between another galley, the desired galley designation within the list is depressed, illuminating the galley to be called. The attendant then presses the telephone icon, initiating a call to the requested galley. Speaker 320 relays the other party's voice to the galley, or a handset can be used. Alternatively, the voice mode can be replaced with a text mode, where communications are entered via a keyboard and a screen displays the communication, both to the passenger and the galley. In this manner, the galley can automatically create two way communication between galleys in the aircraft.
In a preferred embodiment, the galley can also be accessed by a hand-held communication device such as a smart phone, PDA, or other hand held communication device. Using an app or special function on the hand-held device, an attendant can press a button or sequence of buttons to initiate a call to the galley. This leads to further access and communication between the galleys, passengers, and flight attendants. In the case of the hand held device carried by the flight attendant, the screen may display a text of the communication rather than a voice communication in the alternate embodiment.
The following examples are illustrative of the advantages of the communication-linked galley of the present invention. A flight attendant is out on the floor conducting any number of meal services during the flight (see
In yet another example, the purser in the previous example realizes her galley is out of Passenger X's request, and presses the icon corresponding to the adjacent galley and presses the phone icon, initiating a call to the adjacent galley. A purser at the next galley hears a ring tone and quickly looks at the control panel in that galley to see who is calling. She sees that it is the adjacent galley and answers the phone, where the purser in the first galley asks if the product in question is in the adjacent galley. The purser responds that there is, and offers to take the product to Passenger X at his seat location. Thus, the galley to galley communication saves both time and effort in meeting the passenger's demands.
From the foregoing, it can be seen that the integrated galley and communication system can save time, weight, and costs in the galley. Although various embodiments have been described, it is to be understood that various modifications and substitutions would be appreciated by one of ordinary skill in the art, and the present invention is intended to include all such modifications and substitutions. Accordingly, nothing in this specification or the drawings should be construed as limiting or exclusive unless expressly indicated. Rather, the scope of the invention is measured by appended claims, using the plain and ordinary meaning of the words in view of, but not exclusive to, the description herein.
